ABSTRACT

INTRODUCCIÓN: La resección anterior ultrabaja interesfintérica (RAUBIE), permite preservar la función esfinteriana en pacientes seleccionados con cáncer de recto (CR). No obstante, puede producir alteraciones en la función evacuatoria y esfinteriana. OBJETIVO: Analizar los resultados oncológicos y funcionales luego de una RAUBIE. MATERIAL Y MÉTODO: Estudio observacional, analítico, transversal, durante el período 2007 a 2016. Criterios de inclusión: Pacientes sometidos a RAUBIE por CR con intención curativa. Todos los pacientes tuvieron un seguimiento el año 2017. Para la evaluación funcional se usó la escala de Jorge-Wexner, LARS y Kirwan. Análisis estadístico: Estadística descriptiva y método de Kaplan-Meier. RESULTADOS: De 21 pacientes; catorce (67%) fueron varones, edad promedio: 59 años. Ubicación tumoral: 4 cm (2-6 cm) del margen anal. Dieciocho (85,7%) pacientes recibieron neoadyuvancia. Todos los márgenes quirúrgicos distales y radiales fueron negativos. Un paciente (4,8%) tuvo metástasis a distancia y no hubo recurrencia locorregional. Con una mediana de seguimiento de 76,3 (9,8-126,8) meses, la sobrevida global y libre de enfermedad a 5 años fue de: 100% y 95% (IC: 90,1-99,9%), respectivamente. Con una mediana de seguimiento de 90 meses (21,7-124,2); se realizó la evaluación funcional a 15/21 pacientes. El puntaje de Jorge-Wexner tuvo una mediana de 13 (4-17) puntos, la escala de LARS de 34 puntos y en la escala de Kirwan, cuatro pacientes (26,7%) mostraron una buena función (Kirwan I-II). CONCLUSIÓN: Si bien los resultados oncológicos de los pacientes sometidos a una RAUBIE son satisfactorios, se debería tomar en cuenta los resultados funcionales al momento de proponer esta alternativa quirúrgica.

ABSTRACT

ABSTRACT Surgical treatment for low rectal cancer has changed dramatically during the preceding several decades, and the optimal surgical approach remains incompletely developed. Transanal total mesorectal excision is likely the most promising approach for the dissection of the distal part of the mesorectum in a manner that allows for a technically easy and oncologically safe operation. Long after it was first described, the Turnbull-Cutait abdominoperineal pull-through procedure has recently been reintroduced in surgical practice for the treatment of patients with complex anorectal conditions. The current report describes a case of distal rectal cancer involving successful surgical treatment with a combination of the two aforementioned methods and patient discharge without a diverting stoma.


RESUMO tratamento cirúrgico para o câncer de reto baixo mudou drásticamente durante as últimas décadas, mas uma abordagem cirúrgica de excelência ainda continua incompletamente desenvolvida. A excisão total do mesorreto por via transanal parece ser a abordagem mais promissora para a dissecção da parte distal do mesorreto de forma a assegurar uma cirurgia oncológicamente segura com uma técnica simples. Muito depois de sua descrição, o pull-through abdominoperineal de Turnbull-Cutait tem sido reintroduzido na prática cirúrgica para o tratamento de pacientes com enfermidades anorretais complexas. Este relato descreve um caso de câncer de reto baixo que se beneficiou de um tratamento cirúrgico bem sucedido a partir da combinação das duas técnicas supracitadas com o paciente recebendo alta hospitalar sem ostomia de proteção.

ABSTRACT

La derivación biliopancreática con cruce duodenal (BPD-DS) es el procedimiento bariátrico que ha mostrado los mejores resultados en cuanto a pérdida de peso y resolución de comorbilidades. Sin embargo, su adopción ha sido lenta, principalmente debido a sus complicaciones nutricionales y dificultad técnica. Dado esto, algunos autores han propuesto variaciones de este procedimiento. Estas están basadas en disminuir las anastomosis a solo una, y realizarla con un asa tipo loop (sin derivación biliopancreática). Estos cambios podrían reproducir las ventajas del BPD-DS, y eliminar algunas de sus desventajas. En este artículo, mostramos los resultados de estas variaciones comparadas con el BPD-DS, y cómo sus resultados prometedores pueden tener como consecuencia una nueva aproximación a la población que sufre de obesidad y sus comorbilidades


Biliopancreatic Diversion with duodenal switch (BPD-DS) is the bariatric surgery that has shown the better results regarding long-term weight loss and comorbidities resolution. Nevertheless, BPD-DS' adoption has been slow, mainly due to its nutritional complications, and technical complexity. Given this, some authors have proposed surgical variations of this effective procedure. These new procedures are based on reducing the anastomosis to only one, and doing it just a loop anastomosis (no biliopacreatic diversion). These changes might bring to us the advantages of BPD-DS, and eliminate some of its disadvantages. In this article, we show the results of these variations compared with BPD-DS, and how their promising results could be a new approach for obese population and bariatric surgery.

ABSTRACT

INTRODUCCIÓN: La dehiscencia anastomótica (DA) es una complicación severa en cirugía colorrectal con una incidencia que oscila entre 2 y 19%. La literatura internacional muestra numerosos estudios sobre la identificación de factores de riesgo (FR), mientras que en la nacional existen solo dos series que analizan esta complicación. OBJETIVO: Realizar una caracterización descriptiva de resultados institucionales y establecer la tasa de DA, sus factores de riesgo asociados y la mortalidad. MATERIALES Y MÉTODO: Serie de casos no concurrente, cuya muestra son pacientes consecutivos intervenidos de patología colorrectal con anastomosis primaria con o sin ostoma derivativo entre los años 2004 y 2016. Se realiza modelo de regresión logística univariable y multivariable. RESULTADOS: Se obtuvieron 748 pacientes, 50,5% mujeres, media de edad fue 56,2. Las indicaciones quirúrgicas más frecuentes fueron cáncer colorrectal en 381 (50,9%) pacientes y enfermedad diverticular en 163 (21,8%). La DA fue de 5,6% (42/748) y la mortalidad fue de 2% (15/748), siendo de 1% para los electivos (7/681). En el análisis univariado encontramos que los FR que tuvieron significancia estadística fueron la albúmina (p < 0,001), altura anastomosis (p < 0,001), transfusión (p < 0,001), localización (colon derecho > izquierdo) (p = 0,011), mientras que en el análisis multivariado fueron la albúmina (p = 0,002) con un OR 3,64 (IC 95% 1,58-8,35) y transfusión (p = 0,015) con un OR 7,15 (IC 95% 1,46-34,91). CONCLUSIÓN: Nuestra serie es la más grande reportada en Chile, con resultados similares a estudios internacionales y nacionales. Establecemos que la hipoalbuminemia y la presencia de transfusiones intraoperatorias se asocian a alta tasa de DA.


INTRODUCTION: Anastomotic leakage (AL) is a severe complication in colorectal surgery, its incidence ranges from 2 to 19%. In international literature, we found numerous studies on the identification of risk factors (RF), while in the national there are only two series that analyze this complication. AIM: Perform a descriptive characterization of institutional results and establish the AL rate, its associated risk factors and mortality. MATERIALS AND METHOD: Non-concurrent series of cases, whose sample is consecutive patients operated for colorectal pathology with primary anastomosis with or without a derivative ostoma between 2004 and 2016. Univariate and multivariable logistic regression model was performed. RESULTS: There were 748 patients, 50.5% women, mean age was 56.2. The most frequent surgical indications were colorectal cancer in 381 (50.9%) patients and diverticular disease in 163 (21.8%). The AL was 5.6% (42/748) and the mortality was 2% (15/748), being 1% for the electives (7/681). In the univariate analysis, we found that the RF that had statistical significance were albumin (p < 0.001), anastomosis height (p < 0.001), transfusion (p < 0.001), location (right colon > left) (p = 0.011), while that in the multivariate analysis were albumin (p = 0.002) with an OR 3.64 (IC 95% 1.58-8.35) and transfusion (p = 0.015) with an OR 7.15 (IC 95% 1.46-34.91). CONLUSION: Our series is the largest reported in Chile, with similar results to international and national studies. We establish that hypoalbuminemia and the presence of intraoperative transfusions are associated with a high rate of AL.

ABSTRACT

ABSTRACT Background: Although herbal medicinal products are being used widely throughout the World, beneficial and harmful effects have not been well documented. Our aim was to evaluate the effects of Aloe Vera (AV) on colonic anastomosis healing. Material and methods: 112 albino Wistar rats were randomly assigned into five main groups: preoperative Aloe Vera Group (P), pre- and postoperative Aloe Vera Group (PP), Control Group (C), sham Aloe Vera Group (SA) and Sham Control Group (SC). Groups P, PP, and SA received 1.6 mL/kg per day Aloe Vera by orogastric feeding catheter for 1 month prior to the experiment. Groups P, PP, and C underwent anastomosis of the distal colon, and subgroups (n = 4) of each were sacrificed on postoperative day 3, 7, 14 and 21. Anastomotic bursting pressure, perianastomotic collagen content and histopathological changes were studied. Results: The SC Group had significantly higher ABP when compared with the SA Group (p = 0.0002), although hydroxyproline content showed no difference. When ABP was compared between anastomosis groups, it was found significantly lower in Aloe Vera groups on Day 3 (P3 vs. C3, p = 0.003 and PP3 vs. C3, p = 0.007). Hydroxyproline content was significantly lower in Group PP than Group C, also on Day 3 (p = 0.05). Significant difference was not detected after Day 3 in any of the study parameters. Conclusion: Aloe Vera decreased tissue collagen content in the early postoperative period. It is advisable to call into question the concomitant usage of conventional medicine and the herbal supplements for the surgeons in their clinical practice.


RESUMO Fundamentação: Embora os medicamentos à base de plantas sejam amplamente utilizados no mundo inteiro, seus efeitos (benéficos e prejudiciais) não estão bem documentados. Este estudo teve como objetivo avaliar os efeitos da Aloe vera (AV) na cicatrização de anastomoses colônicas. Material e métodos: 112 ratos Wistar albinos foram distribuídos aleatoriamente em cinco grupos principais: AV pré-operatório (P), AV pré e pós-operatório (PP), controle (C), sham AV (SA) e sham controle (SC). Os grupos P, PP e SA receberam AV em uma dose de 1,6 mL/kg por dia por sonda de alimentação orogástrica por 1 mês antes do experimento. Os grupos P, PP e C foram submetidos a anastomose do cólon distal. Subgrupos (n = 4) de cada grupo foram sacrificados no terceiro, sétimo, 14° e 21° dias pós-operatórios. Os seguintes parâmetros foram avaliados: pressão de ruptura anastomótica (PRA), conteúdo de colágeno perianastomótico e alterações histopatológicas. Resultados: O grupo SC apresentou PRA significativamente maior quando comparado ao grupo SA (p = 0,0002), embora o conteúdo de hidroxiprolina não tenha apresentado diferença. Ao comparar a PRA entre os grupos de anastomose, ela foi significativamente menor no terceiro dia nos grupos que usaram AV (P3 vs. C3, p = 0,003 e PP3 vs. C3, p = 0,007). No terceiro dia, o teor de hidroxiprolina foi significativamente menor no grupo PP do que no grupo C (p = 0,05). Após o terceiro dia, não se observou diferença significativa em nenhum dos parâmetros do estudo. Conclusão: O uso de AV diminuiu o conteúdo de colágeno tecidual no período pós-operatório imediato. É aconselhável questionar o uso concomitante da medicina convencional e suplementos fitoterápicos na prática clínica.

ABSTRACT

With the promotion of transanal total mesorectal excision (taTME) nationwide, transanal endoscopic surgery has become more and more widely used. However, at present, there is still a situation in the domestic colorectal surgery community that is not uniform, in-depth and not standardized in the understanding of the issues related to transanal endoscopic surgery. In order to clarify the key issues of transanal endoscopic surgery, including definition, indications, contraindications, surgical classification, basic principles of surgery, prevention and treatment of complications, the experts of the writing committee based on the existing evidence combined with clinical practice to verify the definition of transanal endoscopic surgery, indications, contraindications and surgical classification, by means of voting for key issues such as intraoperative sterility, no tumor principle, surgical quality control, specimen removal method, digestive tract reconstruction, how to solve intraoperative pressure instability, how to ensure the safety of anastomosis, and prevention and treatment of complications, aiming at providing guidance for transanal endoscopic surgery in China.

ABSTRACT

Characterizing inflammation and fibrosis in Crohn's disease (CD) is necessary to guide clinical management, but distinguishing the two remains challenging. Novel ultrasound (US) techniques: contrast-enhanced US (CEUS) and shear wave elastography (SWE) offer great potential in evaluating disease activity in pediatric patients. Three patients ages 16 to 20 with known CD underwent CEUS and SWE to characterize bowel wall inflammation and fibrosis. Magnetic resonance enterography, endoscopy, or surgical pathology findings are also described when available. The patients' disease activity included acute inflammation, chronic inflammation with stricture formation, and a fibrotic surgical anastomosis without inflammation. CEUS was useful in determining the degree of inflammation, and SWE identified bowel wall fibrosis. Used together these techniques allow for better characterization of the degree of fibrosis and inflammation in bowel strictures. With further validation CEUS and SWE may allow for improved characterization of bowel strictures and disease flares in pediatric patients suffering from CD.

ABSTRACT

Abstract Purpose: To develop a new low-cost, easy-to-make and available training model using chickens' intestine for infant intestinal anastomosis. Methods: Segments of chicken intestine were used to create an intestinal anastomosis simulator. We tried to perform an end-to-end, end-to-side and side-to-side anastomosis. Handsewn sutured anastomosis were performed in single layered with interrupted prolene 5-0 suture. The parameters analyzed were cost, intestine's diameter and length, anastomosis patency and flow-through and leakage amount. Results: In all cases it was possible to make the anastomosis in double layered without difficulties, different from the usual ones. There was a positive patency at all anastomoses after the end of the procedure, with no need for reinterventions. Conclusion: The new training model using chickens' intestine for infant intestinal anastomosis is low-cost, easy-to-make and easy available.

ABSTRACT

RESUMO Objetivo: identificar fatores preditivos da síndrome da ressecção anterior do reto (SRAR) que podem contribuir para o seu diagnóstico e tratamento precoces. Métodos: estudo de coorte retrospectivo de pacientes submetidos à ressecção anterior do reto entre 2007 e 2017 no Serviço de Coloproctologia do Hospital de Clínicas da Universidade Federal do Paraná. Foram realizadas análises de curva ROC (Receiver Operating Characteristic Curve Analysis) ou COR (Característica de Operação do Receptor) para identificar os fatores preditivos da SRAR. Resultados: foram incluídos 64 pacientes com dados completos. A idade dos homens foi de 60,1±11,4 anos e 37,10% eram do sexo masculino. Vinte pacientes (32,26%) apresentaram SRAR. Os sintomas mais relatados foram evacuação incompleta (60%) e urgência (55%). Na análise univariada, a distância da anastomose à margem anal (p<0,001), terapia neoadjuvante (p=0,0014) e confecção de ileostomia no momento da ressecção (p=0,0023) foram preditivos da SRAR. Análise da curva ROC mostrou um ponto de corte de 6,5cm na distância da anastomose à margem anal como preditor da SRAR. Conclusão: distância entre anastomose e margem anal, história de terapia neoajuvante e confecção de estoma são condições que podem ajudar a predizer o desenvolvimento da SRAR. A orientação e o envolvimento na educação do paciente, bem como, o manejo precoce podem reduzir potencialmente o impacto desses sintomas na qualidade de vida dos pacientes.


ABSTRACT Objective: to identify predictors of low anterior resection syndrome (LARS) that can contribute to its early diagnosis and treatment. Methods: we conducted a retrospective cohort study of patients undergoing anterior resection of the rectum between 2007 and 2017 in the Coloproctology Service of the Federal University of Parana Clinics Hospital. We performed Receiver Operating Characteristic Curve (ROC) analysis to identify LARS predictive factors. Results: we included 64 patients with complete data. The men's age was 60.1±11.4 years and 37.10% were male. Twenty patients (32.26%) had LARS. The most reported symptoms were incomplete evacuation (60%) and urgency (55%). In the univariate analysis, the distance from the anastomosis to the anal margin (p<0.001), neoadjuvant therapy (p=0.0014) and ileostomy at the time of resection (p=0.0023) were predictive of LARS. The ROC curve analysis showed a 6.5cm cut-off distance from the anastomosis to the anal margin as a predictor of LARS. Conclusion: distance between the anastomosis and the anal margin, neoadjuvant therapy history and preparation of stoma are conditions that can help predict the development of LARS. Guidance and involvement in patient education, as well as early management, can potentially reduce the impact of these symptoms on patients' quality of life.

ABSTRACT

Surgical therapy for adenocarcinoma of the esophagogastric junction II requires distal esophagectomy, in which a transhiatal management of the lower esophagus is critical. The ‘dorsal track control’ (DTC) maneuver presented here facilitates the atraumatic handling of the distal esophagus, in preparation for a circular-stapled esophagojejunostomy. It is based on a ventral semicircular incision in the distal esophagus, with an intact dorsal wall for traction control of the esophagus. The maneuver facilitates the proper placement of the purse-string suture, up to its tying (around the anvil), thus minimizing the manipulation of the remaining esophagus. Furthermore, the dorsally-exposed inner wall surface of the ventrally-opened esophagus serves as a guiding chute that eases anvil insertion into the esophageal lumen. We performed this novel technique in 21 cases, enabling a safe anastomosis up to 10 cm proximal to the Z-line. No anastomotic insufficiency was observed. The DTC technique improves high transhiatal esophagojejunostomy.

ABSTRACT

Totally laparoscopic distal gastrectomy (TLDG) frequently involves the use of delta shaped gastroduodenostomy (DSG) for intracorporeal anastomosis. However, DSG has some drawbacks, and the book binding technique (BBT) was developed as a new technique to overcome these drawbacks. Subsequently, this technique was further improved with the development of modified book binding technique (MBBT). This study evaluated the safety and feasibility of MBBT in patients undergoing TLDG. Thirty-three patients who underwent TLDG with MBBT were retrospectively evaluated. The mean operation time was 277.6±37.1 minutes, including 51.9±15.7 minutes for reconstruction. Two patients had anastomosis-related complications, one patient with stricture after leakage and 1 patient with stenosis. The former patient was treated with endoscopic balloon dilatation, and the latter was managed conservatively; neither required re-operation. MBBT is a safe and feasible technique, with acceptable surgical outcomes. It may be a good alternative option for the treatment of intracorporeal anastomosis in patients undergoing TLDG.

ABSTRACT

PURPOSE: There is no consensus on the optimal method for intracorporeal esophagojejunostomy (EJ) in laparoscopic total gastrectomy (LTG). This study aims to compare 2 established methods of EJ anastomosis in LTG. MATERIALS AND METHODS: A total of 314 patients diagnosed with gastric cancer that underwent LTG in the period from January 2013 to October 2016 were enrolled in the study. In 254 patients, the circular stapler with purse-string “Lap-Jack” method was used, and in the other 60 patients the linear stapling method was used for EJ anastomosis. After propensity score matching, 58 were matched 1:1, and retrospective data for patient characteristics, surgical outcome, and post-operative complications was reviewed. RESULTS: The 2 groups showed no significant difference in age, body mass index, or other clinicopathological characteristics. After propensity score matching analysis, the linear group had shorter operating time than the circular group (200.3±62.0 vs. 244.0±65.5, P≤0.001). Early postoperative complications in the circular and linear groups occurred in 12 (20.7%) and 15 (25.9%, P=0.660) patients, respectively. EJ leakage occurred in 3 (5.2%) patients from each group, with 1 patient from each group needing intervention of Clavien-Dindo grade III or more. Late complications were observed in 3 (5.1%) patients from the linear group only, including 1 EJ anastomosis stricture, but there was no statistical significance. CONCLUSIONS: Both circular and linear stapling techniques are feasible and safe in performing intracorporeal EJ anastomosis during LTG. The linear group had shorter operative time, but there was no difference in anastomosis complications.

ABSTRACT

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.

ABSTRACT

With the development of laparoscopic skills and instruments,totally laparoscopic gastrectomy for gastric cancer has become widely used in the clinic,mainly including totally laparoscopic proximal gastric reconstruction,distal gastrectomy for gastric cancer and total gastrectomy. Digestive tract reconstruction is the key procedure of totally laparoscopic gastrectomy for gastric cancer. Totally laparoscopic surgery has less trauma and better visualization than reconstruction in a small incision. At present,feasibility and safety of totally laparoscopic gastrectomy for gastric cancer have been preliminarily confirmed. However,higher level of evidence is needed for the evaluation of long-term oncologic efficacy. In the future,it is possible for patients to best benefit from totally laparoscopic surgery with minimal trauma,safe anastomosis under the principle of radical resection of gastric cancer. The digestive tract reconstruction includes Delta anastomosis (Billroth I),Billroth II anastomosis,and gastrojejunal Roux-en-Y anastomosis in totally laparoscopic distal gastrectomy (TLDG). Billroth I with delta anastomosis has strict indications in TLDG. Gastrojejunal Roux-en-Y anastomosis is now more popular. Billroth II with Braun anastomosis and uncut Roux-en-Y anastomosis is technically easier to carry out in TLDG than Roux-en-Y. Totally laparoscopic proximal gastric reconstruction includes esophagogastric stump anastomosis,esophagogastric tubular anastomosis and interposition jejunostomy. The digestive tract reconstruction includes anastomosis using linear stapler and circular stapler in totally laparoscopic total gastrectomy (TLTG). In order to better serve the clinic,we review the progress of different endoscopic anastomotic techniques and digestive tract reconstruction.

ABSTRACT

Colorectal anastomosis remains a key aspect in mid- and lower-rectal surgery, particularly in patients who are male, obese, status post neoadjuvant chemoradiation, or possess narrow pelvic anatomy. Transanal total mesorectal excision (taTME) and transabdominal total mesorectal excision (TME) both primarily allow position of the tumor to dictate whether circular stapling or hand-sewing is utilized to achieve anastomosis. Given that taTME only requires a single circular stapler to achieve anastomosis, it consequently decreases the risk of jeopardizing blood supply to the anastomotic site. Should transanal hand-sewing be pursued, numerous points in performing the purse-string suture warrant particular attention: (1) Before suturing, separate the distal rectum to be anastomosed from the surrounding tissues, and ensure the full-layer suture of the distal purse-stitched suture. (2) It is recommended that beginners complete the suturing process under direct visualization without removing the transanal platform. (3) Commonly used anastomosis designs include end-to-end, side-to-end, J-pouch, or coloplasty, depending on patient characteristics and surgeon preferences. Our single-institution clinical experience suggests that taTME patients who underwent neoadjuvant chemoradiation or transanal hand-sewn anastomosis should still have a temporary colostomy created. To date, literature has yet to demonstrate the superiority of taTME anastomosis outcomes. This publication aims to point out anastomosis techniques and safety pointers, as well as clinical experiences.
