Duplicación del colédoco asociado a unión biliopancreática anómala: Reporte de caso / Common bile duct duplication associated with anomalous biliopancreatic junction: A case report

Introducción. La duplicación del colédoco es una anomalía congénita poco frecuente. En la mayoría de los casos este defecto se asocia a cálculos en la vía biliar, unión pancreatobiliar anómala, pancreatitis, cáncer gástrico o colangiocarcinoma. Por esta razón, el diagnóstico y el tratamiento temprano son importantes para evitar las complicaciones descritas a futuro. Métodos. Se presenta el caso de una paciente de 30 años, con antecedente de pancreatitis aguda, con cuadro de dolor abdominal crónico, a quien se le realizaron varios estudios imagenológicos sin claro diagnóstico. Fue llevada a manejo quirúrgico en donde se documentó duplicación del colédoco tipo II con unión pancreatobiliar anómala. Resultados. Se hizo reconstrucción de las vías biliares y hepatico-yeyunostomía, con adecuada evolución postoperatoria y reporte final de patología sin evidencia de tumor. Conclusión. El diagnóstico se hace mediante ecografía endoscópica biliopancreática, colangiorresonancia o colangiopancreatografía retrógrada endoscópica. El tratamiento depende de si está asociado o no a la presencia de unión biliopancreática anómala o cáncer. Si el paciente no presenta patología neoplásica, el tratamiento quirúrgico recomendado es la resección del conducto con reconstrucción de las vías biliares.

Introduction. Double common bile duct is an extremely rare congenital anomaly. This anomaly may be associated with bile duct stones, anomalous biliopancreatic junction, pancreatitis, bile duct cancer, or gastric cancers. Thus, early diagnosis and treatment is important to avoid complications. Clinical case. We report a rare case of double common bile duct associated with an anomalous biliopancreatic junction in a 30-year-old female, with prior history of acute pancreatitis, who presented with chronic abdominal pain. She underwent several imaging studies, without clear diagnosis. She was taken to surgical management where duplication of the type II common bile duct was documented with anomalous pancreatobiliary junction. Results. Reconstruction of the bile ducts and hepatico-jejunostomy were performed, with adequate postoperative evolution and final pathology report without evidence of tumor. Conclusion. Diagnosis is usually performed by an endoscopic ultrasound, magnetic resonance cholangiopancrea-tography, or endoscopic retrograde cholangiopancreatography. Treatment depends on the presence of anomalus biliopancreatic junction or concomitant cancer. In cases without associated malignancy, resection of bile duct and biliary reconstruction is the recommended surgical treatment.

Comparison of long-term quality of life between Billroth-I and Roux-en-Y anastomosis after distal gastrectomy for gastric cancer: a randomized controlled trial / 中华医学杂志(英文版)

BACKGROUND@#The results of studies comparing Billroth-I (B-I) with Roux-en-Y (R-Y) reconstruction on the quality of life (QoL) are still inconsistent. The aim of this trial was to compare the long-term QoL of B-I with R-Y anastomosis after curative distal gastrectomy for gastric cancer.@*METHODS@#A total of 140 patients undergoing curative distal gastrectomy with D2 lymphadenectomy in West China Hospital, Sichuan University from May 2011 to May 2014 were randomly assigned to the B-I group ( N  = 70) and R-Y group ( N  = 70). The follow-up time points were 1, 3, 6, 9, 12, 24, 36, 48, and 60 months after the operation. The final follow-up time was May 2019. The clinicopathological features, operative safety, postoperative recovery, long-term survival as well as QoL were compared, among which QoL score was the primary outcome. An intention-to-treat analysis was applied.@*RESULTS@#The baseline characteristics were comparable between the two groups. There were no statistically significant differences in terms of postoperative morbidity and mortality rates, and postoperative recovery between the two groups. Less estimated blood loss and shorter surgical duration were found in the B-I group. There were no statistically significant differences in 5-year overall survival (79% [55/70] of the B-I group vs. 80% [56/70] of the R-Y group, P  = 0.966) and recurrence-free survival rates (79% [55/70] of the B-I group vs. 78% [55/70] of the R-Y group, P  = 0.979) between the two groups. The scores of the global health status of the R-Y group were higher than those of the B-I group with statistically significant differences (postoperative 1 year: 85.4 ± 13.1 vs . 88.8 ± 16.1, P  = 0.033; postoperative 3 year: 87.3 ± 15.2 vs . 92.8 ± 11.3, P  = 0.028; postoperative 5 year: 90.9 ± 13.7 vs . 96.4 ± 5.6, P  = 0.010), and the reflux (postoperative 3 year: 8.8 ± 12.9 vs . 2.8 ± 5.3, P  = 0.001; postoperative 5 year: 5.1 ± 9.8 vs . 1.8 ± 4.7, P  = 0.033) and epigastric pain (postoperative 1 year: 11.8 ± 12.7 vs. 6.1 ± 8.8, P  = 0.008; postoperative 3 year: 9.4 ± 10.6 vs. 4.6 ± 7.9, P  = 0.006; postoperative 5 year: 6.0 ± 8.9 vs . 2.7 ± 4.6, P  = 0.022) were milder in the R-Y group than those of the B-I group at the postoperative 1, 3, and 5-year time points.@*CONCLUSIONS@#Compared with B-I group, R-Y reconstruction was associated with better long-term QoL by reducing reflux and epigastric pain, without changing survival outcomes.@*TRIAL REGISTRATION@#ChiCTR.org.cn, ChiCTR-TRC-10001434.

Short-term outcomes and long-term quality of life after undergoing radical proximal gastrectomy with esophageal gastric tube anastomosis and total gastrectomy with Roux-en-Y anastomosis for Siewert type II and III adenocarcinoma of the esophagogastric junction: A propensity score matching analysis / 中华胃肠外科杂志

Objective: To evaluate the effects on short-term clinical outcomes and long-term quality of life of laparoscopic-assisted radical proximal gastrectomy with esophageal gastric tube anastomosis versus total gastrectomy with Roux-en-Y anastomosis for adenocarcinoma of the esophagogastric junction. Methods: This was a propensity score matching, retrospective, cohort study. Clinicopathological data of 184 patients with adenocarcinoma of the esophagogastric junction admitted to two medical centers in China from January 2016 to January 2021 were collected (147 in the First Affiliated Hospital of Xiamen University and 37 in the Affiliated Hospital of Qinghai University). All patients had undergone laparoscopic-assisted radical gastrectomy. They were divided into two groups based on the extent of tumor resection and technique used for digestive tract reconstruction. A proximal gastrectomy with reconstruction by esophageal gastric tube anastomosis group comprised 82 patients and a total gastrectomy with reconstruction by Roux-en-Y anastomosis group comprised 102 patients. These groups differed significantly in the following baseline characteristics: age, preoperative hemoglobin, preoperative albumin, tumor length, tumor differentiation, and tumor TNM stage (all P<0.05). To eliminate potential bias caused by unequal distribution between the two groups, 1∶1 matching was performed by the nearest neighbor matching method. The 13 matched variables comprised sex, age, height, body mass, body mass index, preoperative glucose, preoperative hemoglobin, preoperative total protein, preoperative albumin, neoadjuvant radiotherapy, tumor length, degree of differentiation, and pathological TNM stage. Postoperative complications, postoperative nutritional status, incidence of reflux esophagitis 1 year after surgery, and quality of life were compared between the two groups. Results: After propensity score matching, 60 patients each were enrolled in the proximal gastrectomy with esophageal gastric tube anastomosis and total gastrectomy with Roux-en-Y anastomosis groups. The baseline characteristics were comparable between these groups (all P>0.05). There were no significant differences between the two groups in operative time, intraoperative bleeding, time to semifluid diet, postoperative hospital days, tumor length, and total hospital costs (P>0.05). Patients in the proximal gastrectomy with esophageal gastric tube anastomosis group had earlier postoperative gastric tube and abdominal drainage tube removal time than those in the total gastrectomy with Roux-en-Y anastomosis group (t=-2.183, P=0.023 and t=-4.073, P<0.001, respectively). In contrast, significantly fewer lymph nodes were cleared and significantly fewer lymph nodes were positive in the proximal gastrectomy with esophageal gastric tube anastomosis group than in the total gastrectomy with Roux-en-Y anastomosis group (t=-5.754, P<0.001 and t=-2.575, P=0.031, respectively). The incidence of early postoperative complications was 43.3% (26/60) in the total gastrectomy with Roux-en-Y anastomosis group; this is not significantly higher than the 26.7% (16/60) in the proximal gastrectomy with esophageal gastric tube anastomosis group (χ2=3.663，P=0.056). The incidences of pulmonary infection (31.7%, 19/60) and pleural effusion (30.0%, 18/60) were significantly higher in the total gastrectomy with Roux-en-Y anastomosis group than in the proximal gastrectomy with esophageal gastric tube anastomosis group (13.3%, 8/60 and 8.3%, 5/60, respectively); these differences are significant (χ2=8.711, P=0.003 and χ2=11.368, P=0.001, respectively). All early complications were successfully treated before discharge. The incidence of long-term postoperative complications was 20.0% (12/60) in the total gastrectomy with Roux-en-Y anastomosis group and 35.0% (21/60) in the proximal gastrectomy with esophageal gastric tube anastomosis group; this difference is not significant (χ2=3.386，P=0.066). The incidence of reflux esophagitis was 23.3% (14/60) in the proximal gastrectomy with esophageal gastric tube anastomosis group; this is significantly higher than the 1.7% (1/60) in the total gastrectomy with Roux-en-Y anastomosis group (χ2=12.876, P<0.001). Body mass index had decreased significantly in both groups 1 year after surgery compared with preoperatively; however, the difference between the two groups was not significant (P>0.05). The differences in hemoglobin and albumin concentrations between 1 year postoperatively and preoperatively were not significant (both P>0.05). Quality of life was assessed using the Visick grade. Visick grade I dominated in both groups. The percentage of patients with Visick II and III in the total gastrectomy with Roux-en-Y anastomosis group was 11.7% (7/60), which is significantly lower than the 33.3% (20/60) in the proximal gastrectomy with esophageal gastric tube anastomosis group (χ2=8.076, P=0.004). No patients in either group had a grade IV quality of life. Conclusions: Both proximal gastrectomy with esophageal gastric tube anastomosis and total gastrectomy with Roux-en-Y anastomosis laparoscopic-assisted radical surgery for adenocarcinoma of the esophagogastric junction are safe and feasible. However, both procedures have their own advantages and disadvantages in terms of postoperative complications. The incidence of reflux esophagitis is higher after proximal gastrectomy with esophageal gastric tube anastomosis, whereas the long-term quality of life is lower than that of patients after total gastrectomy with Roux-en-Y anastomosis.

Trauma hepático grave con compromiso vascular y fuga biliar. Reporte de dos casos / Severe liver trauma with vascular compromise and biliary leak. Report of two cases

Introducción: El hígado se lesiona con mayor frecuencia en un trauma de abdomen de alta energía, con una incidencia entre 1 % y 8 %. Las lesiones traumáticas de las vías biliares son muy raras. Casos clínicos: Presentamos dos pacientes con trauma hepático grave, y compromiso ex-trahepático vascular y de la vía biliar; y el abordaje quirúrgico para preservar funcional-mente ambos lóbulos: Masculino de 1 año, trauma hepático grado V, lesión incompleta de vena porta derecha, a nivel de la bifurcación y del conducto biliar hepático izquierdo. Se reparó el daño portal y de la vía biliar. Femenina de dos años, trauma cerrado de abdomen, lesión del parénquima de lóbulo derecho del hígado, sección total del conducto hepático izquierdo, y contusión pancreática asociada. En ambos casos se realizó una hepáticoyeyunostomía en Y de Roux y conservación de ambos lóbulos. Conclusión: En los traumas complejos hepáticos que involucran ambos lóbulos, la evolución depende de calidad de la masa residual. La cirugía conservadora con reconstrucciones vasculares y biliares, evita un fallo hepático agudo, permite ganar tiempo hasta la regeneración funcional del parénquima y proteger de una eventual insuficiencia hepática post-operatoria.

Introduction: The liver is more frequently injured in high-energy abdominal trauma, with an incidence between 1% and 8%. Traumatic injuries to the bile ducts are infrequent. Clinical cases: We present two patients with severe liver trauma and extrahepatic vascular and bile duct involvement and the surgical approach to preserve both lobes functionally: 1-year-old male, grade V liver trauma, incomplete injury to the right portal vein, at the level of the bifurca-tion and the left hepatic bile duct. The portal and bile duct damage was repaired. Two-year-old female, blunt abdominal trauma, injury to the parenchyma of the right lobe of the liver, whole section of the left hepatic duct, and associated pancreatic contusion. In both cases, a Roux-en-Y hepatic jejunostomy was performed, and both lobes were preserved. Conclusion: In complex liver trauma involving both lobes, the evolution depends on the quality of the residual mass. Conservative surgery with vascular and biliary reconstructions avoids acute liver failure, allows time to gain until the funct.

Terapia de presión negativa para el manejo de abdomen catastrófico secundario a íleo biliar / Negative Pressure Therapy for Managing Catastrophic Abdomen following Gallstone Ileus

Introducción: El abdomen catastrófico o abdomen hostil es una entidad quirúrgica de gran importancia por la pérdida de los distintos espacios entre los órganos de la cavidad abdominal y las estructuras de la cavidad abdominal. Estas alteraciones producen cambios anatómicos grandes por un síndrome adherencial severo. Objetivo: Demostrar la presentación de un abdomen catastrófico posterior a manejo de íleo biliar en un paciente adulto. Caso clínico: Paciente masculino de 43 años que producto de un abdomen agudo obstructivo por íleo biliar evolucionó tórpidamente en otra casa asistencial. Se realizaron 3 intervenciones quirúrgicas, hasta llegar a nuestra casa asistencial donde se le trata de manera multidisciplinaria e integral. Estuvo 120 días hospitalizado y se le realizó 5 intervenciones quirúrgicas para aplicación y recambio de terapia de presión negativa abdominal abierta (ABThera). Durante la última intervención al encontrar una cavidad limpia y sin fugas se realiza gastroentero anastomosis en Y de Roux con una buena evolución clínico-quirúrgica hasta el alta, con seguimiento dos meses posteriores por consulta externa. Conclusiones: El abdomen catastrófico es un reto para el manejo por los cirujanos porque se requiere aparte de un vasto conocimiento también el apoyo de otras especialidades para poder combatir esta entidad(AU)

Introduction: Catastrophic abdomen or hostile abdomen is a surgical entity of great significance due to the loss of the different spaces between organs and the structures of the abdominal cavity. These alterations produce major anatomical changes due to a severe adhesive syndrome. Objective: To show the presentation of a catastrophic abdomen following gallstone ileus management in an adult patient. Clinical case: A 43-year-old male patient who, as a consequence of an acute obstructive abdomen due to gallstone ileus, had a torpid evolution into another care facility. Three surgical interventions were performed before he arrived at our care facility, where he was treated in a multidisciplinary and comprehensive way. He was hospitalized for 120 days and underwent five surgical interventions for application and replacement of the open abdomen negative pressure therapy (ABThera). During the last intervention, upon finding a clean cavity without leaks, a Roux-en-Y gastroenteric anastomosis was performed, with a good clinical-surgical evolution until discharge and follow-up of two months thereafter in the outpatient clinic. Conclusions: Catastrophic abdomen is a challenge to be managed by surgeons because it requires, apart from vast knowledge, the support of other specialties to combat this entity(AU)

Complicaciones nutricionales de la cirugía bariátrica / 9 NUTRITIONAL COMPLICATIONS OF BARIATRIC SURGERY

La cirugía bariátrica es reconocida como una terapia altamente efectiva para la obesidad, ya que logra una pérdida de peso sostenida, una reducción de las comorbilidades y la mortalidad relacionadas con la obesidad; además mejora de la calidad de vida de los pacientes. Sin embargo, las deficiencias nutricionales son un problema inherente en el período postoperatorio y, a menudo, requieren una suplementación de por vida. Los tipos de desnutrición después de la cirugía incluyen desnutrición proteico-energética y deficiencias de micronutrientes, como hierro, ácido fólico, vitamina A y vitamina B12. Lamentablemente, no existen regímenes estandarizados de cuidados posteriores, y los costos de los suplementos nutricionales los pagan los propios pacientes. Esta revisión se enfoca en el estudio de la desnutrición poscirugía bariátrica, recorriendo las principales deficiencias y sus causas

Bariatric surgery is recognized as a highly effective therapy for obesity, as it achieves sustained weight loss, a reduction in comorbidities and obesity-related mortality; It also improves the quality of life of patients. However, nutritional deficiencies are an inherent problem in the postoperative period and often require lifelong supplementation. Types of malnutrition after surgery include protein-energy malnutrition and micronutrient deficiencies, such as iron, folic acid, vitamin A, and vitamin B12. Currently, there are no standardized aftercare systems, and the costs of nutritional supplements are paid by the patients themselves. This review focuses on the study of malnutrition after bariatric surgery, covering the main deficiencies and their causes.

Efficacy of laparoscopic proximal gastrectomy with double-tract reconstruction versus laparoscopic total gastrectomy with Roux-en-Y reconstruction for early upper gastric cancer / 中华胃肠外科杂志

Objective: To compare clinical efficacy between laparoscopic radical proximal gastrectomy with double-tract reconstruction (LPG-DTR) and laparoscopic radical total gastrectomy with Roux-en-Y reconstruction (LTG-RY) in patients with early upper gastric cancer, and to provide a reference for the selection of surgical methods in early upper gastric cancer. Methods: A retrospective cohort study method was carried out. Clinical data of 80 patients with early upper gastric cancer who underwent LPG-DTR or LTG-RY by the same surgical team at the Department of General Surgery, the First Affiliated Hospital of Xi'an Jiaotong University from January 2018 to January 2021 were retrospectively analyzed. Patients were divided into the DTR group (32 cases) and R-Y group (48 cases) according to surgical procedures and digestive tract reconstruction methods. Surgical and pathological characteristics, postoperative complications (short-term complications within 30 days after surgery and long-term complications after postoperative 30 days), survival time and nutritinal status were compared between the two groups. For nutritional status, reduction rate was used to represent the changes in total protein, albumin, total cholesterol, body mass, hemoglobin and vitamin B12 levels at postoperative 1-year and 2-year. Non-normally distributed continuous data were presented as median (interquartile range), and the Mann-Whitney U test was used for comparison between groups. The χ(2) test or Fisher's exact test was used for comparison of data between groups. The Mann-Whitney U test was used to compare the ranked data between groups. The survival rate was calculated by Kaplan-Meier method categorical, and compared by using the log-rank test. Results: There were no statistically significant differences in baseline data betweeen the two groups, except that patients in the R-Y group were oldere and had larger tumor. Patients of both groups successfully completed the operation without conversion to laparotomy, combined organ resection, or perioperative death. There were no significant differences in the distance from proximal resection margin to superior margin of tumor, postoperative hospital stay, time to flatus and food-taking, hospitalization cost, short- and long-term complications between the two groups (all P>0.05). Compared with the R-Y group, the DTR group had shorter distal margins [(3.2±0.5) cm vs. (11.7±2.0) cm, t=-23.033, P<0.001], longer surgery time [232.5 (63.7) minutes vs. 185.0 (63.0) minutes, Z=-3.238, P=0.001], longer anastomosis time [62.5 (17.5) minutes vs. 40.0 (10.0) minutes, Z=-6.321, P<0.001], less intraoperative blood loss [(138.1±51.6) ml vs. (184.3±62.1) ml, t=-3.477, P=0.001], with significant differences (all P<0.05). The median follow-up of the whole group was 18 months, and the 2-year cancer-specific survival rate was 97.5%, with 100% in the DTR group and 95.8% in the R-Y group (P=0.373). Compared with R-Y group at postoperative 1 year, the reduction rate of weight, hemoglobin and vitamin B12 were lower in DTR group with significant differences (all P<0.05); at postoperative 2-year, the reduction rate of vitamin B12 was still lower with significant differences (P<0.001), but the reduction rates of total protein, albumin, total cholesterol, body weight and hemoglobin were similar between the two groups (all P>0.05). Conclusions: LPG-DTR is safe and feasible in the treatment of early upper gastric cancer. The short-term postoperative nutritional status and long-term vitamin B12 levels of patients undergoing LPG-DTR are superior to those undergoing LTG-RY.

Choice of digestive tract reconstruction in upper gastric cancer / 中华胃肠外科杂志

With the increasing incidence of upper gastric cancer and early gastric cancer, surgeons have gradually paid attention to the selection of appropriate digestive tract reconstruction methods. At present, the safety of surgery is no longer the main aim pursued by surgeons, and the focus of surgery has gradually changed to postoperative quality of life. Surgical procedures for upper gastric cancer include total gastrectomy (TG) and proximal gastrectomy (PG). Roux-en-Y anastomosis is recommended for digestive tract reconstruction after TG. The classic method of digestive tract reconstruction after PG is distal residual stomach and esophageal anastomosis. However, to prevent esophageal reflux caused by PG, a lot of explorations have been carried out over the years, including tubular gastroesophageal anastomosis, double-flap technique (Kamikawa anastomosis), interposition jejunum, double-tract reconstruction and so on. But the appropriate method of digestive tract reconstruction for upper gastric cancer is still controversial. In this paper, based on literatures and our clinical experience, the selection, surgical difficulties and techniques of digestive tract reconstruction after PG are discussed.

Technical difficulties and countermeasures of digestive tract reconstruction in robotic radical gastrectomy for gastric cancer / 中华胃肠外科杂志

There still remain some problemsin digestive tract reconstruction after robotic radical gastrectomy for gastric cancer at present, such as great surgical difficulties and high technical requirements. Based on the surgical experience of the Gastric Surgery Department of Union Hospital, Fujian Medical University and the literatures at home and abroad, relevant issues are discussed in terms of robotic radical distal gastrectomy (Billroth I, Billroth II, and Roux-en-Y gastrojejunostomy), proximal gastrectomy (double-channel and double-muscle flap anastomosis), and total gastrectomy (Roux-en-Y anastomosis, functional end-to-end anastomosis, FEEA, π-anastomosis, Overlap anastomosis, and modified Overlap anastomosis with delayed amputation of jejunum, i.e. later-cut Overlap). This article mainly includes (1) The principles of digestive tract reconstruction after robotic radical gastrectomy for gastric cancer. (2) Digestive tract reconstruction after robotic radical distal gastrectomy: Aiming at the weakness of traditional triangular anastomosis, we introduce the improvement of the technical difficulty, namely "modified triangular anastomosis", and point out that because Billroth II anastomosis is a common anastomosis method in China at present, manual suture under robot is more convenient and safe, and can effectively avoid anastomotic stenosis. (3) Digestive tract reconstruction after robotic proximal gastrectomy: It mainly includes double channel anastomosis and double muscle flap anastomosis, but these reconstruction methods are relatively complicated, and robotic surgery has not been widely carried out at present. (4) Digestive tract reconstruction after robotic total gastrectomy: The most classic one is Roux-en-Y anastomosis, mainly using circular stapler for end-to-side esophagojejunal anastomosis and linear stapler for side-to-side esophagojejunal anastomosis, for which we discuss the solutions to the existing technical difficulties. With the continuous innovation of robotic surgical system and anastomosis instruments, and with the gradual improvement of anastomosis technology, it is believed that digestive tract reconstruction after robotic radical gastrectomy for gastric cancer will have a good application prospect in gastric cancer surgery.

Experience and thoughts on digestive tract reconstruction after radical resection of adenocarcinoma of the esophagogastric junction / 中华胃肠外科杂志

In the surgical treatment of adenocarcinoma of the esophagogastric junction (AEG), the scope of lymph node dissection, surgical approach selection, extent of tumor resection and digestive tract reconstruction have always been controversial, with the digestive tract reconstruction in AEG facing many challenges especially. The digestive tract reconstruction is related to the extent of resection. At present, the digestive tract reconstruction after total gastrectomy includes Roux-en-Y anastomosis, jejunum interposition and its derivatives. According to different reconstruction methods, they can be divided into tube anastomosis, linear anastomosis and manual anastomosis. Anti-reflux digestive tract reconstruction after proximal gastrectomy mainly includes esophagogastric anastomosis, interposition jejunum and double channel anastomosis. At present, double channel anastomosis is the most common reconstruction method in China. Based on the concept of interposition tubular stomach and reconstruction of gastric angle for anti-reflux, we propose "Giraffe" anastomosis, which moves artificial fundus and His angle downward to retain more residual stomach, showing good gastric emptying and anti-reflux effect. In this paper, combined with our clinical experience and understanding, we discuss the selection and technical key points of digestive tract reconstruction methods in AEG, and suggest that composite anti-reflux mechanism design may be the development trend of anti-reflux reconstruction in the future. The composite mechanism includes the retention of gastric electrical pacemaker in greater curvature of the middle part of gastric body to increase the emptying capacity of residual stomach, the reconstruction of gastric fundus and His angle anti-reflux barrier, and the establishment of an interposition tubular stomach acting as a buffer zone in Giraffe construction, and so on.

Comparison of clinical efficacy and quality of life between uncut Roux-en-Y and Billroth II with Braun anastomosis in laparoscopic distal gastrectomy for gastric cancer / 中华胃肠外科杂志

Objective: To compare the clinical efficacy and quality of life between uncut Roux-en-Y and Billroth II with Braun anastomosis in laparoscopic distal gastrectomy for gastric cancer patients. Methods: A retrospective cohort study was performed. Inclusion criteria: (1) 18 to 75 years old; (2) gastric cancer proved by preoperative gastroscopy, CT and pathological results and tumor was suitable for D2 radical distal gastrectomy; (3) postoperative pathological diagnosis stage was T1-4aN0-3M0 (according to the AJCC-7th TNM tumor stage), and the margin was negative; (4) Eastern Cooperative Oncology Group (ECOG) physical status score <2 points, and American Association of Anesthesiologists (ASA) grade 1 to 3; (5) no mental illness; (6) able to answer questionnaires independently; (7) patients agreed to undergo laparoscopic distal gastrectomy and signed an informed consent. Exclusion criteria: (1) patients with severe chronic diseases and American Association of Anesthesiologists (ASA) grade >3; (2) patients with other malignant tumors; (3) patients suffered from serious mental diseases; (4) patients received neoadjuvant chemotherapy or immunotherapy. According to the above criteria, clinical data of 200 patients who underwent laparoscopic distal gastrectomy at the Department of General Surgery of the First Affiliated Hospital of Army Medical University from January 2016 to December 2019 were collected. Of the 200 patients, 108 underwent uncut Roux-en-Y anastomosis and 92 underwent Billroth II with Braun anastomosis. The general data, intraoperative and postoperative conditions, complications, and endoscopic evaluation 1 year after the surgery were compared. Besides, the quality of life of two groups was also compared using the Chinese version of the European Organization For Research and Treatment of Cancer (EORTC) quality of life questionnaire-Core 30 (QLQ-C30) and quality of life questionnaire-stomach 22 (QLQ-STO22). Results: There were no significant differences in baseline data between the two groups (all P>0.05). All the 200 patients successfully underwent laparoscopic distal gastrectomy without intraoperative complications, conversion to open surgery or perioperative death. There were no significant differences between two groups in operative time, intraoperative blood loss, postoperative complications, time to flatus, time to removal of gastric tube, time to liquid diet, time to removal of drainage tube or length of postoperative hospital stay (all P>0.05). Endoscopic evaluation was conducted 1 year after surgery. Compared to Billroth II with Braun group, the uncut Roux-en-Y group had a significantly lower incidences of gastric stasis [19.8% (17/86) vs. 37.0% (27/73), χ(2)=11.199, P=0.024], gastritis [11.6% (10/86) vs. 34.2% (25/73), χ(2)=20.892, P<0.001] and bile reflux [1.2% (1/86) vs. 28.8% (21/73), χ(2)=25.237, P<0.001], and the differences were statistically significant. The EORTC questionnaire was performed 1 year after surgery, there were no significant differences in the scores of QLQ-C30 scale between the two groups (all P>0.05), while the scores of QLQ-STO22 showed that, compared to the Billroth II with Braun group, the uncut Roux-en-Y group had a lower pain score (median: 8.3 vs. 16.7, Z=-2.342, P=0.019) and reflux score (median: 0 vs 5.6, Z=-2.284, P=0.022), and the differences were statistically significant (all P<0.05), indicating milder symptoms. Conclusion: The uncut Roux-en-Y anastomosis is safe and reliable in laparoscopic distal gastrectomy, which can reduce the incidences of gastric stasis, gastritis and bile reflux, and improve the quality of life of patients after surgery.

Effect of duodenal stump reinforcement on postoperative complications in patients undergoing laparoscopic radical gastrectomy / 中华胃肠外科杂志

Objective: To evaluate the influence of duodenal stump reinforcing on the short-term complications after laparoscopic radical gastrectomy. Methods: A retrospective cohort study with propensity score matching (PSM) was conducted. Clinical data of 1204 patients with gastric cancer who underwent laparoscopic radical gastrectomy at the First Affiliated Hospital of Army Medical University from April 2009 to December 2018 were collected. The digestive tract reconstruction methods included Billroth II anastomosis, Roux-en-Y anastomosis and un-cut-Roux- en-Y anastomosis. A linear stapler was used to transected the stomach and the duodenum. Among 1204 patients, 838 were males and 366 were females with mean age of (57.0±16.0) years. Duodenal stump was reinforced in 792 cases (reinforcement group) and unreinforced in 412 cases (non-reinforcement group). There were significant differences in resection range and anastomotic methods between the two groups (both P<0.001). The two groups were matched by propensity score according to the ratio of 1∶1, and the reinforcement group was further divided into purse string group and non-purse string group. The primary outcome was short-term postoperative complications (within one month after operation). Complications with Clavien-Dindo grade ≥ III a were defined as severe complications, and the morbidity of complication between the reinforcement group and the non-reinforcement group, as well as between the purse string group and the non-purse string group was compared. Results: After PSM, 411 pairs were included in the reinforcement group and the non-reinforcement group, and there were no significant differences in baseline data between the two groups (all P>0.05). No perioperative death occurred in any patient.The short-term morbidity of postoperative complication was 7.4% (61/822), including 14 cases of anastomotic leakage (23.0%), 11 cases of abdominal hemorrhage (18.0%), 8 cases of duodenal stump leakage (13.1%), 2 cases of incision dehiscence (3.3%), 6 cases of incision infection (9.8%) and 20 cases of abdominal infection (32.8%). Short-term postoperative complications were found in 25 patients (6.1%) and 36 patients (8.8%) in the reinforcement group and the non-reinforcement group, respectively, without significant difference (χ2=2.142, P=0.143). Nineteen patients (2.3%) developed short-term severe complications (Clavien-Dindo grade ≥IIIa), while no significant difference in severe complications was found between the two groups (1.7% vs. 2.9%, χ2=1.347, P=0.246). Sub-group analysis showed that the morbidity of short-term postoperative complication of the purse string group was 2.6% (9/345), which was lower than 24.2% (16/66) of the non-purse string group (χ2=45.388, P<0.001). Conclusion: Conventional reinforcement of duodenal stump does not significantly reduce the incidence of duodenal stump leakage, so it is necessary to choose whether to reinforce the duodenal stump individually, and purse string suture should be the first choice when decided to reinforce.

Limb length in bariatric surgery of Roux-en-Y gastric bypass (RYGB): An integrative review / Longitud del asa intestinal en la cirugía bariátrica de bypass gástrico en Y de Roux (BGYR): Una revisión integradora

Introduction: Roux-en-Y gastric bypass is considered the gold standard surgical technique for obesity. The variation in limb length may be related to metabolic improvement and nutritional deficiencies. However, the ideal measurement still a controversial subject in the literature. This study aims to perform an integrative literature review and associate the optimal limb length, considering the maximum weight loss with the minimum nutritional complications. Methods: Integrative literature review conducted using electronic searches (1992 - 2020) in databases MEDLINE/Pubmed and BVS (Biblioteca Virtual da Saúde)/LILACS, through the terms "(bariatric surgery) AND (limb length)".A total of 340 articles were found, 26 articles were included in this review. Results: Current evidence supports using shorter limb lengths in patients with BMI < 50 kg/m2, and longer limbs in patients with severe type 2 diabetes mellitus and/or dyslipidemia or superobese patients (BMI >= 50 kg/m2), considering the benefits in comorbidities resolution. A shorter common limb increases the inci-dence of nutritional disorders. There is a wide variation in jejunoileal length among patients. Conclusion: Measuring the intraoperative jejunoileal length and individualizing the surgery may bring benefits in weight loss, comorbidities resolution, and reduce the incidence of nutritional disorders. However, more randomized controlled trials are needed on this topic.

Introducción: el bypass gástrico en Y de Roux se considera la técnica quirúrgica estándar de oro para la obesidad. La variación en la longitud del asa intestinalpuede estar relacionada con la mejora metabólica y las deficiencias nutricionales, sin embargo, la longitud ideal sigue siendo un tema controvertido en la literatura. El objetivo de este estudio es realizar una revisión integradora de la literatura y asociar la longitud ideal del asa intestinal, considerando la máxima pérdida de peso con las mínimas complicaciones nutricionales. MaterialesyMétodos: revisión bibliográfica integradora realizada mediante búsquedas electrónicas (1992 - 2020) en bases de datos MEDLINE/Pubmed y BVS (Biblioteca Virtual da Saúde) / LILACS, a través de los términos "(bariatric surgery) AND (limb length)". Se encon-traron un total de 340 artículos, 26 artículos fueron incluidos en esta revisión.Resultados: la evidencia actual respalda el uso de asas intestinales más cortas en pacientes con IMC < 50 kg/m2 y asas intestinales más largas en pacientes con diabetes mellitus tipo 2 grave y/o dislipidemia o pacientes superobesos (IMC > = 50 kg/m2), considerando los beneficios en la resolución de comorbilidades. La asa común más corto aumenta la incidencia de trastornos nutricionales. Existe una amplia variación en la longitud yeyunoileal entre los pacientes. Conclusiones: la medición de la longitud yeyunoileal intraoperatoria y la individualización de la cirugía pueden traer beneficios en la pérdida de peso, la resolución de comorbilidades y reducir la incidencia de trastornos nutricionales. Sin embargo, se necesitan más ensayos controlados aleatorios sobre este tema.

Shorten preoperative fasting and introducing early eating assistance in recovery after gastrojejunal bypass? / Abreviar jejum pré-operatório e introduzir alimentação precoce auxiliam na recuperação após bypass gastrojejunal?

ABSTRACT Rational: The metabolic response to surgical trauma is enhanced by prolonged preoperative fasting, contributing to increased insulin resistance. This manifestation is more intense on the 1st and 2nd postoperative days and is directly proportional to the size of the operation. Aim: To compare whether preoperative fasting abbreviation and early postoperative refeeding associated with intraoperative and postoperative fluid restriction interfere in the evolution of patients undergoing gastrojejunal bypass. Methods: Eighty patients indicated for Roux-en-Y gastrojejunal bypass were selected. They were randomly divided into two groups: Ringer Lactate (RL) group, who underwent a 6 hours solids fasting, with the administration of 50 g of maltodextrin in 100 ml of mineral water 2 hours before the beginning of anesthesia; and Physiologic Solution (PS) group, who underwent a 12 hours solids and liquids fasting. Anesthesia was standardized for both groups. During the surgical procedure, 1500 ml of ringer lactate solution was administered in the RL and 2500 ml of physiological solution (0.9% sodium chloride) in the PS. In both groups, the occurrence of bronchoaspiration was analyzed during intubation, and the residual gastric volume was measured after opening the abdominal cavity. In the postoperative period in Group RL, patients started a liquid diet 24 hours after the end of the operative procedure; whilst for PS group, fasting was maintained for the first 24 hours, it was prescripted 2000 ml of physiological solution and a restricted liquid diet after 36 hours. Each patient underwent CPK, insulin, sodium, potassium, urea, creatinine, PaCO2, pH and bicarbonate dosage in the immediate postoperative period, and 48 hours later, the exams were repeated. Results: There were no episodes of bronchoaspiration and gastrojejunal fistulas in either group. In the analysis of the residual gastric volume of the PS and RL groups, the mean volumes were respectively 16.5 and 8.8, which shows statistical significance between the groups. In laboratory tests, there was no difference between groups in sodium; PS group showed a higher level of serum potassium (p=0.029); whilst RL group showed a higher urea and creatinine values; CPK values were even for both; PS group demonstrated a higher insulin level; pH was higher in PS group; sodium bicarbonate showed a significant difference at all times; PaCO2 values in RL group was higher than in PS. In the analysis of the incidence of nausea and flatus, no statistical significance was observed between the groups. Conclusions: The abbreviation of preoperative fasting and early postoperative refeeding of Roux-en-Y gastrojejunal bypass with the application of ERAS or ACERTO Project accelerated the patient's recovery, reducing residual gastric volume and insulin level, and do not predispose to complications.

RESUMO Racional: A resposta metabólica ao trauma cirúrgico é potencializada pelo jejum pré-operatório prolongado que contribui para o aumento da resistência à insulina. Esta manifestação é mais intensa no 1º e 2º dias de pós-operatório e é diretamente proporcional ao porte da operação. Objetivo: Comparar se a abreviação do jejum pré-operatório e a realimentação precoce no pós-operatório associado à restrição hídrica no trans e pós-operatório interferem na evolução dos pacientes submetidos ao bypass gastrojejunal. Métodos: Foram recrutados 80 pacientes indicados ao bypass gastrojejunal em Y-de-Roux. Eles foram distribuídos randomicamente em dois grupos: ringer lactato (RL) que fizeram jejum de 6 h para sólidos, administrando 50 g de maltodextrina em 100 ml de água mineral 2 h antes do início da anestesia e de soro fisiológico (SF) que fizeram jejum de 12 h para sólidos e líquidos. A anestesia foi padronizada para os dois grupos. Durante o procedimento operatório no RL foi administrado 1500 ml solução de ringer lactato e no SF 2500 ml de soro fisiológico (0,9% de cloreto de sódio). Em ambos os grupos foram analisados durante a intubação a ocorrência ou não de bronco-aspiração e mensurado o volume gástrico residual após abertura da cavidade abdominal. No pós-operatório do Grupo RL, os pacientes iniciaram dieta liquida após 24 h do término do procedimento operatório; no Grupo SF foi mantido jejum nas primeiras 24 h, prescrição de 2000 ml de soro fisiológico e início da dieta líquida restrita com 36 h. Cada paciente realizou no pós-operatório imediato, ainda na sala de cirurgia, a dosagem de CPK, insulina, sódio, potássio, ureia, creatinina, PaCO2, pH e bicarbonato e em 48 h repetiu-se a coleta destes exames. Resultados: Não houve episódios de broncoaspiração e fístulas gastrojejunais em ambos os grupos. Na análise do volume residual gástrico dos grupos SF e RL, as médias de volume foram respectivamente 16,5 e 8,8 apresentando significância estatística entre os grupos. Nos exames laboratoriais não houve diferença entre os grupos no sódio; nível sérico de potássio no SF foi maior (p=0,029); ureia e creatinina maiores no RL; CPK não apresentou diferenças; insulina no grupo SF foram maiores; pH foi maior no SF; bicarbonato de sódio evidenciou diferença significativa em todos o momentos; PaCO2 no RL foi maior. Na análise de incidência de náusea e flatos não foram observados significância estatística entre os grupos. Conclusões: A abreviação do jejum pré-operatório e a realimentação precoce no pós-operatório de bypass gastrojejunal em Y-de-Roux com a aplicação de programas como ERAS ou Projeto Acerto aceleram a recuperação do paciente, diminuindo o volume gástrico residual e o nível de insulina, e não predispõem complicações.

Aspectos da hipertensão arterial sistêmica antes e após a cirurgia bariátrica do tipo Fobi capella com desvio de y de Roux / Aspects of systemic arterial hypertension before and after fobi capella with deviation Roux-en-y bariatric surgery

A obesidade é uma doença crônica multifatorial que desencadeia diversas comorbidades, sendo a hipertensão arterial uma das principais complicações, tornando-se um risco para o desenvolvimento das doenças cardiovasculares e mortalidade precoce. Assim, este estudo objetivou abordar os aspectos da hipertensão relacionada à obesidade antes e após a realização de cirurgia bariátrica. Tratou-se de um estudo descritivo, envolvendo indivíduos de ambos os gêneros, com idade superior a 18 anos submetidos à cirurgia bariátrica pelo método Fobi Capella com desvio de Y de Roux na cidade de Toledo-PR. Para tanto, 30 participantes responderam um questionário semiestruturado investigando dados sobre a pressão arterial. Os resultados demonstraram que no pré-operatório 66,66% dos avaliados apresentavam hipertensão, sendo os gêneros igualmente afetados, 46,66% referiram três ou mais sintomas da comorbidade e escore de saúde mental (40,8 ±16,7) com repercussão relevante. No pós-operatório os parâmetros de normalidade da pressão arterial foram evidenciados em todos os participantes, 57,14% deixaram de necessitar de medicação de controle e houve uma melhora exponencial do escore de saúde mental (81,9 ±21,7). Concluindo que a cirurgia bariátrica compõe um tratamento altamente eficaz para perda ponderal de peso corroborando para normalização da pressão arterial, redução dos sintomas da hipertensão, da necessidade de tratamento medicamentoso para essa finalidade e melhora da saúde geral do indivíduo.

Obesity is a chronic multifactorial disease that triggers several comorbidities, with arterial hypertension being one of the main complications, becoming a risk for the development of cardiovascular diseases and early mortality. Thus, this study aimed at addressing aspects of hypertension related to obesity before and after bariatric surgery. This is a descriptive study, involving individuals of both genders, aged over 18 years submitted to bariatric surgery by the Fobi Capella method with deviation of Roux-en-Y in the city of Toledo, in the state of Paraná, Brazil. For that purpose, 30 participants answered a semi-structured questionnaire investigating blood pressure data. The results showed that in the pre-surgery period, 66.66% of the patients had arterial hypertension, and the genres were equally affected; 46.66% reported three or more symptoms of comorbidity and mental health score (40.8 ± 16.7) with relevant repercussions. In the post-surgery period, normal blood pressure parameters were evident in all participants, 57.14% no longer required control medication and there was an exponential improvement in the mental health score (81.9 ± 21.7), thus concluding that bariatric surgery is a highly effective treatment for weight loss, corroborating blood pressure normalization, reduction of symptoms of hypertension, the need for drug treatment for this purpose and improvement of the individual's general health.

Gastrectomía vertical versus by-pass gástrico en Y de Roux: resultados a corto y medio plazo / Sleeve gastrectomy vs gastric bypass: results in the short and medium term

Resumen Introducción: La gastrectomía vertical (GV) y el by-pass gástrico (BPG) son los procedimientos más utilizados en el tratamiento de la obesidad. El objetivo de este trabajo es comparar ambas técnicas tanto en pérdida ponderal como en mejoría de las comorbilidades asociadas. Materiales y Método: Estudio observacional ambispectivo de los pacientes sometidos a BPG y GV desde enero de 2011 hasta diciembre de 2013. Se ha analizado la pérdida de peso y de IMC, la tasa de éxito, la reganancia de peso, el impacto en las comorbilidades asociadas y la morbimortalidad de ambas técnicas. Resultados: 172 pacientes fueron intervenidos (92 BPG y 80 GV). El BPG presenta mejores resultados en cuanto a pérdida de peso y mejoría de las comorbilidades. El grupo GV presenta mayor reganancia de peso. Ambos procedimientos presentan resultados similares en cuanto a morbimortalidad.

Introduction: Sleeve gastrectomy (SG) and gastric bypass (GBP) are the most commonly used procedures in the treatment of obesity. The objective of this paper is to compare these two techniques in regard to weight loss and improvement of the associated comorbidities. Material and Method: An ambispective observational study of patients undergoing GBP and SG from January 2011 to December 2013. Weight loss, BMI, success rate, weight regain, impact on associated comorbidities and morbimortality of both techniques were analysed. Results: 172 patients underwent operations (92 GBP and 80 SG). GBP had better results in regard to weight loss and improvement of comorbidities. The SG group had greater weight regain. The two procedures had similar results in regard to morbimortality.

Failure after fundoplication: re-fundoplication? is there a room for gastrectomy? in which clinical scenaries? / Falha após fundoplicatura: re-fundoplicatura? existe oportunidade para gastrectomia? em quais cenários clínicos?

ABSTRACT Background: Re-fundoplication is the most often procedure performed after failed fundoplication, but re-failure is even higher. Aim: The objectives are: a) to discuss the results of fundoplication and re-fundoplication in these cases, and b) to analyze in which clinical situation there is a room for gastrectomy after failed fundoplication. Method: This experience includes 104 patients submitted to re-fundoplication after failure of the initial operation, 50 cases of long segment Barrett´s esophagus and 60 patients with morbid obesity, comparing the postoperative outcome in terms of clinical, endoscopic, manometric and 24h pH monitoring results. Results: In patients with failure after initial fundoplication, redo-fundoplication shows the worst clinical results (symptoms, endoscopic esophagitis, manometry and 24 h pH monitoring). In patients with long segment Barrett´s esophagus, better results were observed after fundoplication plus Roux-en-Y distal gastrectomy and in obese patients similar results regarding symptoms, endoscopic esophagitis and 24h pH monitoring were observed after both fundoplication plus distal gastrectomy or laparoscopic resectional gastric bypass, while regarding manometry, normal LES pressure was observed only after fundoplication plus distal gastrectomy. Conclusion: Distal gastrectomy is recommended for patients with failure after initial fundoplication, patients with long segment Barrett´s esophagus and obese patients with gastroesophageal reflux disease and Barrett´s esophagus. Despite its higher morbidity, this procedure represents an important addition to the surgical armamentarium.

RESUMO Racional: Re-fundoplicatura é o procedimento mais frequentemente realizado após falha na fundoplicatura, mas neste caso a falha é ainda maior. Objetivo: a) discutir os resultados da fundoplicatura e re-fundoplicatura nesses casos; e b) analisar em que situação clínica há espaço para gastrectomia após falha na fundoplicatura. Método: Esta experiência inclui 104 pacientes submetidos à re-fundoplicatura após falha da operação inicial, sendo 50 casos de esôfago de Barrett de segmento longo e 60 pacientes com obesidade mórbida, comparando-se o resultado pós-operatório em termos de pH clínico, endoscópico, manométrico de 24 h de monitoramento. Resultados: Em pacientes com falha após a fundoplicatura inicial, a re-fundoplicatura mostra os piores resultados clínicos (sintomas, esofagite endoscópica, manometria e pHmetria 24 h). Em pacientes com esôfago de Barrett de segmento longo, melhores resultados foram observados após fundoplicatura com gastrectomia distal em Y-de-Roux e em pacientes obesos resultados semelhantes em relação aos sintomas, esofagite endoscópica e monitoramento de pH 24 h foram observados após fundoplicatura com gastrectomia distal ou ressecção com bypass gástrico laparoscópico, enquanto que em relação à manometria, a pressão normal do EEI só foi observada após a fundoplicatura e gastrectomia distal. Conclusão: A gastrectomia distal é recomendada para pacientes com falha após a fundoplicatura inicial, pacientes com esôfago de Barrett de segmento longo e obesos com doença do refluxo gastroesofágico e esôfago de Barrett. Apesar de sua maior morbidade, esse procedimento representa um importante acréscimo ao arsenal cirúrgico.

Application of intracorporeal uncut Roux-en-Y anastomosis in digestive tract reconstruction after laparoscopic total gastrectomy / 中华胃肠外科杂志

OBJECTIVE@#To explore the safety, feasibility and short-term efficacy of intracavitary uncut Roux-en-Y (URY) anastomosis in digestive tract reconstruction following laparoscopic total gastrectomy (LTG).@*METHODS@#From November 2015 to January 2018, 67 gastric cancer patients underwent intracavitary URY following LTG to reconstruct the digestive tract at Oncological Surgery Department of Fujian Provincial Hospital. There were 41 males and 26 females with age of 50 to 81 (61.9±7.4) years and body mass index (BMI) of (23.4±3.2) kg/m². Among 67 patients, 19 were gastric cardia carcinomas, 33 were gastric body carcinomas, and 15 were gastric fundus carcinomas; tumor size was (3.4±2.3) cm; 22 were Borrmann type I, 15 were type II, 21 were type III, and 19 were type IV; 29 were highly or moderately differentiated adenocarcinoma, 23 were lowly differentiated adenocarcinoma, and 15 were signet-ring cell carcinoma. After conventional laparoscopic D2 radical gastrectomy, the duodenum was closed and dissociated at 2 cm below the pyloric ring using the Echelon-flex endoscopic articulated linear Endo-GIA stapler, and the esophagus was dissociated above the esophagogastric junction (EGJ).URY and digestive tract reconstruction were performed under the direct vision of laparoscope: (1) Side-to-side esophagojejunostomy: An incision of 0.5 cm was made in the left lower edge of the esophageal closed end; jejunum about 25 cm distal away from the Treitz ligament was elevated to the lower end of esophagus; another incision of 0.5 cm was made in the contralateral of mesenteric side; both arms of the linear Endo-GIA stapler were inserted into the windows opened through esophagus and jejunum respectively to complete side-to-side anastomosis. The common opening of esophagus and jejunum was closed to complete esophagojejunostomy, forming the chyme outflow tract. (2) Side-to-side Braun jejunojejunostomy: Incisions of 0.5 cm were made in the proximal jejunum about 10 cm away from the esophagojejunal anastomosis and 35-40 cm away from the contralateral of mesenteric side of distal jejunum respectively for proximal-distal side-to-side jejunojejunostomy. The common opening was closed to form the biliopancreatic duodenal juice outflow tract. (3) Closure of the input loop jejunum in the esophagojejunal anastomosis: The input loop jejunum 2-3 cm away from the esophagojejunal anastomosis was closed using the non-blade linear stapler (ATS45NK), and the biliopancreatic duodenal juice reflux was blocked. Clinical data of these patients were collected for retrospective case series study. Surgical and digestive tract functional recovery, perioperative complications, as well as postoperative nutritional status were observed. Moreover, related indexes, such as anastomosis function and tumor recurrence were evaluated through endoscopic and imaging examinations during postoperative follows-up.@*RESULTS@#All the 67 patients completed the surgery successfully. The mean operative time was (259.4±38.5) minutes, digestive tract reconstruction time was (38.2±13.2) minutes, intraoperative blood loss was (73.4±38.4) ml, and number of harvested lymph node was 36.2±14.2. The mean distance from upper resection margin to upper tumor edge was (3.3±1.2) cm, distance from upper resection margin to dentate line was (1.2±0.7) cm, and 1 case had positive upper incisal margin, which became negative after the second resection. Moreover, the average length of the auxiliary incision was (3.2±0.4) cm. The mean postoperative intestinal exhaust time was (52.8±26.4) hours, time to liquid diet was (64.8±28.8) hours, and postoperative hospital stay was (8.4±2.5) days. The morbidity of postoperative complication was 10.4%(7/67). Among these 7 cases, 4 cases were grade IIIa of Clavien-Dindo classification, including 2 with esophagojejunal anastomosis leakage, 1 with duodenal stump leakage, and 1 with abdominal infection, and all these patients were recovered after conservative treatment. All the 67 patients were followed up. The mean nutrition index 12 months after surgery was 53.4±4.2, diameter of esophagojejunal anastomosis was (3.9±0.6) cm, the incidence of Roux-en-Y stasis syndrome was 3.0% (2/67), and the incidence of reflux esophagitis was 4.5% (3/67). No patient had recanalization of the closed input loop of esophagojejunal anastomosis, anastomotic stenosis, obstruction, or tumor recurrence at anastomosis.@*CONCLUSION@#Intracavitary URY anastomosis following LTG for digestive tract reconstruction is safe and feasible, leading to fast postoperative recovery of digestive tract function and favorable short-term efficacy.
