Analysis of Clinical Efficacy and Quality of Life of Braun Anastomosis in Gastrointestinal Reconstruction in Totally Laparoscopic Distal Gastrectomy: A Single-Center Retrospective Study.

OBJECTIVE: This study aimed to compare the clinical efficacy and quality of life of B-IIB (Billroth-II with Braun anastomosis) and B-II (Billroth-II anastomosis) in the alimentary tract reconstruction postoperative totally laparoscopic distal gastrectomy (TLDG) for gastric cancer. METHODS: From February 2016 to January 2022, 158 patients underwent totally laparoscopic distal gastrectomy and D2 lymphadenectomy in Northern Jiangsu People's Hospital, with Billroth-II with Braun anastomosis for 93 patients and Billroth-II anastomosis for 65 patients. The patients' data were collected prospectively and reviewed retrospectively. RESULTS: In this study, the post-op hospital stay of B-IIB group were shorter than B-II group (12.70 ± 3.08 days in the B-IIB group versus 14.12 ± 4.90 days in the B-II group, p < 0.05) and the first post-op flatus time of the B-IIB group were shorter than B-II group (3.49 ± 1.02 days versus 4.08 ± 1.85 days, p < 0.05). Two groups did differ significantly in hemoglobin on postoperative 3 months, albumin at 3 months after operation, and serum sodium on postoperative 3 days and 3 months (p < 0.05), and the B-IIB had an advantage; the complications incidence (Clavien-Dindo grade II or even a higher grade) of the B-IIB group and B-II group were 10.75% and 29.23%, respectively. There being a statistical difference between the two groups. The B-IIB group and the B-II group both had different degrees of weight loss at 3 months after operation compared with preoperative weight. The weight of B-IIB group was 4.04 ± 1.33 kg, which was less than B-II group (8.08 ± 1.47 kg). The difference was statistically significant (p < 0.05). According to the PGSAS (Postgastrectomy Syndrome Assessment Scale), the score of the B-IIB group is lower than that of the B-II group for esophageal reflux gastritis, dyspepsia, and dumping syndrome group (1.84 ± 0.92 VS 2.15 ± 0.85, P = 0.031; 1.86 ± 1.10 VS 2.22 ± 0.91, P = 0.034; 1.98 ± 1.06 VS 2.32 ± 0.94, P = 0.037, respectively). CONCLUSION: Totally laparoscopic distal gastrectomy with Billroth-II Braun reconstruction is a safe and technically feasible method for gastric cancer patients, which can reduce the incidence of postoperative reflux esophagitis and dumping syndrome. Compared with Billroth-II reconstruction, it has advantages in maintaining postoperative nutritional status and electrolyte balance and improving quality of life.

Choledochoduodenostomy combined with Billroth II procedure for extrahepatic biliary obstruction and duodenal perforation in a cat.

Case summary: A 5-year-old neutered Somali cat presented with a 2-week history of icterus. Diagnostic imaging revealed extrahepatic biliary obstruction (EHBO) due to a common bile duct (CBD) mass. During exploratory laparotomy, a duodenal perforation was discovered incidentally. Choledochoduodenostomy combined with the Billroth II procedure was performed after resection of the CBD mass and the proximal duodenum to treat the EHBO and duodenal perforation. Based on histological and immunohistochemical findings, the CBD mass was diagnosed as a neuroendocrine carcinoma with gastrin-producing cell differentiation. The cat recovered almost uneventfully and was discharged 11 days after surgery. The cat survived for nearly 100 days without recurrence of EHBO or duodenal perforation; however, intermittent vomiting and weight loss persisted despite supportive medications. Relevance and novel information: To the best of our knowledge, there is no detailed report on the application of choledochoduodenostomy combined with the Billroth II procedure in cats, as we used to treat the EHBO and duodenal perforation in the present case. As serum gastrin concentrations were elevated on the first day of hospitalisation, the CBD mass was diagnosed as a neuroendocrine carcinoma with gastrin-producing cell differentiation, which seemed to have caused not only EHBO but also duodenal perforation (Zollinger-Ellison syndrome). The cat survived for almost 100 days without any perioperative complications. However, this combined procedure might be considered as only a salvage option and not as a definitive treatment option in cats requiring simultaneous biliary and gastrointestinal reconstruction because postoperative supportive care could not improve the cat's condition or maintain its quality of life.

Afferent loop syndrome 7-years post Roux-en-Y gastrojejunostomy: An often-forgotten pancreatitis cause. A case report.

Afferent loop syndrome is a rare post-operative complication following upper gastrointestinal bypass surgeries, usually occurring within the first two weeks post-operation. This case report, however, outlines afferent loop syndrome almost a decade post-surgery, which was managed conservatively. A 54-year-old woman presented with a few days' history of epigastric pain, vomiting, and constipation. She had undergone a sleeve gastrectomy and was converted to a Roux-en-Y gastrojejunostomy for weight loss 9 and 7 years ago, respectively. Serum lipase was elevated at 1410 IU/L. Computed tomography showed high-grade proximal small bowel obstruction, involving the efferent and afferent loops of the Roux-en-Y gastric bypass. The patient was given intravenous rehydration, electrolyte replacement and had a nasogastric tube inserted. She was discharged on day 5 of admission without significant sequelae. Afferent limb syndrome should be considered in patients with altered upper gastrointestinal anatomy who present with pancreatitis, regardless of the time period post-operatively. Future guidelines should further more outline the factors indicated for surgical versus conservative management.

Practical application of the modification in endoscopic retrograde cholangiopancreatography treated common bile duct stones in patients with Billroth II gastroenterostomy in Vietnam.

Objective: Endoscopic retrograde cholangiopancreatography (ERCP) in patients who have undergone Billroth II gastroenterostomy (B-II GE) has been challenging, requiring flexibility in technical approaches during execution. The study aims to assess the effectiveness of enhanced techniques in performing ERCP on this patient group in Vietnam. Method: A total of 42 Vietnamese patients with B-II GE performed an ERCP using a duodenoscope or a modification of ERCP equipment (a cap-fitted regular forward-viewing endoscope) if the former failed. The effectiveness and safety of the ERCP technique were assessed, particularly in patients who underwent the forward-viewing endoscope method. Result: A total of 39 out of 42 patients had the Vater's papilla identified, among whom 12 patients (30.8%) achieved successful cannulation into the bile duct using a side-viewing endoscope, significantly lower than the success rate using a forward-viewing endoscope (25/27, counted 92.6%, with p < 0.001). After successful cannulation, the rate of stone clearance, the procedural time, and the hospitalization duration of the patients were equivalent between the two methods and were not dependent on the number or size of the stones. On the other hand, post-ERCP complications in patients utilizing forward-viewing endoscopy included acute pancreatitis (22.2%), post-sphincterotomy bleeding (3.7%), septicemia (4.8%), and perforation (0%). These complications were mild and amenable to conservative endoscopic and medical management, and no mortality was observed. The rates of complications and adverse events after ERCP are comparable between the two treatment methods, even though the end-viewing endoscope is used after the failure of the side-viewing endoscope. Conclusion: Alter ERCP utilizing a cap-fitted forward-viewing endoscope can be a primary choice for treating common bile duct stones in patients with a Billroth II gastric resection history because of high efficacy and acceptable complications. It requires a high level of procedural expertise that requires multiple training sessions.

The promising change in the treatment approach for common bile duct stones in Vietnamese patients with a history of Billroth II gastrectomy Endoscopic retrograde cholangiopancreatography (ERCP) treating common bile duct stones in Vietnamese patients with a history of Billroth II gastrectomy is challenging due to changes in gastric anatomy and the limited visibility of the side-viewing endoscope. The researchers tried different techniques, including using a special type of forward-viewing endoscope with cap assistance. We found that using a forward-viewing endoscope was more successful in reaching certain areas compared to a side-viewing one. Although there were some complications, they were manageable, and the overall results were similar between the two methods. The study suggests that using a modified approach with a forward-viewing endoscope with cap assistance can be a good option for treating common bile duct stones in patients with a history of Billroth II gastric resection, but it requires skilled practitioners.

Billroth II anastomosis combined with brown anastomosis reduce reflux gastritis in gastric cancer patients.

BACKGROUND: The surgeon performing a distal gastrectomy, has an arsenal of reconstruction techniques at his disposal, Billroth II among them. Braun anastomosis performed during a Billroth II procedure has shown evidence of superiority over typical Billroth II, in terms of survival, with no impact on postoperative morbidity and mortality. AIM: To compare Billroth II vs Billroth II and Braun following distal gastrectomy, regarding their postoperative course. METHODS: Patients who underwent distal gastrectomy during 2002-2021, were separated into two groups, depending on the surgical technique used (Billroth II: 74 patients and Billroth II and Braun: 28 patients). The daily output of the nasogastric tube (NGT), the postoperative day that NGT was removed and the day the patient started per os feeding were recorded. Postoperative complications were at the same time noted. Data were then statistically analyzed. RESULTS: There was difference in the mean NGT removal day and the mean start feeding day. Mean total postoperative NGT output was lower in Braun group (399.17 mL vs 1102.78 mL) and it was statistically significant (P < 0.0001). Mean daily postoperative NGT output was also statistically significantly lower in Braun group. According to the postoperative follow up 40 patient experienced bile reflux and alkaline gastritis from the Billroth II group, while 9 patients who underwent Billroth II and Braun anastomosis were presented with the same conditions (P < 0.05). CONCLUSION: There was evidence of superiority of Billroth II and Braun vs typical Billroth II in terms of bile reflux, alkaline gastritis and NGT output.

Italian Survey on Endoscopic Biliary Drainage Approach in Patients with Surgically Altered Anatomy.

Background and Objectives: Biliary drainage (BD) in patients with surgically altered anatomy (SAA) could be obtained endoscopically with different techniques or with a percutaneous approach. Every endoscopic technique could be challenging and not clearly superior over another. The aim of this survey is to explore which is the standard BD approach in patients with SAA. Materials and Methods: A 34-question online survey was sent to different Italian tertiary and non-tertiary endoscopic centers performing interventional biliopancreatic endoscopy. The core of the survey was focused on the first-line and alternative BD approaches to SAA patients with benign or malignant obstruction. Results: Out of 70 centers, 39 answered the survey (response rate: 56%). Only 48.7% of them declared themselves to be reference centers for endoscopic BD in SAA. The total number of procedures performed per year is usually low, especially in non-tertiary centers; however, they have a low tendency to refer to more experienced centers. In the case of Billroth-II reconstruction, the majority of centers declared that they use a duodenoscope or forward-viewing scope in both benign and malignant diseases as a first approach. However, in the case of failure, the BD approach becomes extremely heterogeneous among centers without any technique prevailing over the others. Interestingly, in the case of Roux-en-Y, a significant proportion of centers declared that they choose the percutaneous approach in both benign (35.1%) and malignant obstruction (32.4%) as a first option. In the case of a previous failed attempt at BD in Roux-en-Y, the subsequent most used approach is the EUS-guided intervention in both benign and malignant indications. Conclusions: This survey shows that the endoscopic BD approach is extremely heterogeneous, especially in patients with Roux-en-Y reconstruction or after ERCP failure in Billroth-II reconstruction. Percutaneous BD is still taken into account by a significant proportion of centers in the case of Roux-en-Y anatomy. The total number of endoscopic BD procedures performed in non-tertiary centers is usually low, but this result does not correspond to an adequate rate of referral to more experienced centers.

Optimal reconstruction methods after distal gastrectomy for gastric cancer: a protocol for a systematic review and network meta-analysis update.

BACKGROUND: Distal gastrectomy (DG) is a commonly used surgical procedure for gastric cancer (GC), with three reconstruction methods available: Billroth I, Billroth II, and Roux-en-Y. In 2018, our team published a systematic review to provide guidance for clinical practice on the optimal reconstruction method after DG for GC. However, since then, new evidence from several randomized controlled trials (RCTs) has emerged, prompting us to conduct an updated systematic review and network meta-analysis to provide the latest comparative estimates of the efficacy and safety of the three reconstruction methods after DG for GC. METHOD: This systematic review and network meta-analysis update followed the PRISMA-P guidelines and will include a search of PubMed, Embase, and the Cochrane Library for RCTs comparing the outcomes of Billroth I, Billroth II, or Roux-en-Y reconstruction after DG for patients with GC. Two independent reviewers will screen the titles and abstracts based on predefined eligibility criteria, and two reviewers will assess the full texts of relevant studies. The Bayesian network meta-analysis will evaluate various outcomes, including quality of life after surgery, anastomotic leakage within 30 days after surgery, operation time, intraoperative blood loss, major postoperative complications within 30 days after surgery, incidence and severity of bile reflux, and loss of body weight from baseline. ETHICS AND DISSEMINATION: The review does not require ethical approval. The findings of the review will be disseminated through publication in an academic journal, presentations at conferences, and various media outlets. INPLASY REGISTRATION NUMBER: INPLASY2021100060.

Short- and long-term outcomes of Roux-en-Y and Billroth II with Braun reconstruction in total laparoscopic distal gastrectomy: a retrospective analysis.

BACKGROUND: The controversy surrounding Roux-en-Y (R-Y) and Billroth II with Braun (BII + B) reconstruction as an anti-bile reflux procedure after distal gastrectomy has persisted. Recent studies have demonstrated their efficacy, but the long-term outcomes and postoperative quality of life (QoL) among patients have yet to be evaluated. Therefore, we compared the short-term and long-term outcomes of the two procedures as well as QoL. METHODS: The clinical data of 151 patients who underwent total laparoscopic distal gastrectomy (TLDG) at the Gastrointestinal Surgery Department of the Second Hospital of Fujian Medical University from January 2016 to December 2019 were retrospectively analyzed. Of these, 57 cases with Roux-en-Y procedure (R-Y group) and 94 cases with Billroth II with Braun procedure were included (BII + B group). Operative and postoperative conditions, early and late complications, endoscopic outcomes at year 1 and year 3 after surgery, nutritional indicators, and quality of life scores at year 3 postoperatively were compared between the two groups. RESULTS: The R-Y group recorded a significantly longer operative time (194.65 ± 21.52 vs. 183.88 ± 18.02 min) and anastomotic time (36.96 ± 2.43 vs. 27.97 ± 3.74 min) compared to the BII + B group (p < 0.05). However, no other significant differences were observed in terms of perioperative variables, including blood loss (p > 0.05). Both groups showed comparable rates of early and late complications. Endoscopic findings indicated similar food residuals at years 1 and 3 post-surgery for both groups. The R-Y group had a lower occurrence of residual gastritis and bile reflux at year 1 and year 3 after surgery, with a statistically significant difference (p < 0.001). Reflux esophagitis was not significantly different between the R-Y and BII + B groups in year 1 after surgery (p = 0.820), but the R-Y group had a lower incidence than the BII + B group in year 3 after surgery (p = 0.023). Nutritional outcomes at 3 years after surgery did not differ significantly between the two groups (p > 0.05). Quality of life scores measured by the QLQ-C30 scale were not significantly different between the two groups. However, on the QLQ-STO22 scale, the reflux score was significantly lower in the R-Y group than in the BII + B group (0 [0, 0] vs. 5.56 [0, 11.11]) (p = 0.003). The rest of the scores were not significantly different (p > 0.05). CONCLUSION: Both R-Y and B II + B reconstructions are equally safe and efficient for TLDG. Nevertheless, the R-Y reconstruction reduces the incidence of residual gastritis, bile reflux, and reflux esophagitis, as well as postoperative reflux symptoms, and provides a better quality of life for patients. R-Y reconstruction is superior to BII + B reconstruction for TLDG.

Billroth-I anastomosis in distal subtotal gastrectomy for non-early gastric adenocarcinoma.

BACKGROUND: Billroth-I (B-I) anastomosis is known as a simple and physiological reconstruction method after distal subtotal gastrectomy for early gastric cancer. Yet its role and oncological validity in non-early gastric adenocarcinoma (NEGA) remain unclear. PATIENTS AND METHODS: Patients with NEGA without distant metastases operated between May 2004 and December 2020 were included. Surgical and oncologic outcomes of distal subtotal gastrectomy were studied in patients with B-I and Billroth II (B-II) anastomoses. Propensity score matching (PSM) was used to adjust for age, gender, tumor size, location, resection type, pT and pN stages. RESULTS: A total number of 332 patients underwent distal subtotal gastrectomy for NEGA followed by B-I and B-II anastomoses in 165 (49.7%) and 167 (50.3%) cases, respectively. B-I was applied in patients with smaller tumor size, less advanced pT stage and tumor location in the gastric antrum. The former was also associated with lower proportion of multiorgan resections and shorter operative time. After PSM, these differences became statistically non-significant, except operative time. Postoperative outcomes were similar before and after PSM. Greater lymph node yield was observed in patients with B-I anastomosis. The incidence of recurrence, specifically local recurrence was lower in patients with B-I anastomosis. However, this association was not statistically significant in the multivariable model. Median overall survival was 38 months, without significant differences between the groups. CONCLUSIONS: The use of B-I anastomosis after distal subtotal gastrectomy for NEGA is associated with satisfactory surgical and oncologic outcomes. B-I anastomosis should be considered as a valid reconstruction method in these patients.

Side-Viewing Duodenoscope versus Forward-Viewing Gastroscope for Endoscopic Retrograde Cholangiopancreatography in Billroth II Gastrectomy Patients.

Introduction: Endoscopic retrograde cholangiopancreatography (ERCP) in patients with Billroth II gastrectomy is still a challenging procedure. The optimal approach, namely the type of endoscope and sphincter management, has yet to be defined. Aim: To compare the efficacy and safety of forward-viewing gastroscope and the side-viewing duodenoscope in ERCP of patients with Billroth II gastrectomy. Methods: We conducted a retrospective, single-center cohort study of consecutive patients with Billroth II gastrectomy submitted to ERCP in an expert center for ERCP between 2005 and 2021. The outcomes assessed were: papilla identification, deep biliary cannulation, and adverse events (AEs). Multivariate analysis was performed to evaluate potential associations and predictors of the main outcomes. Results: We included 83 patients with a median age of 73 (IQR 65-81) years. ERCP was performed using side-viewing duodenoscope in 52 and forward-viewing gastroscope in 31 patients. Patients' characteristics were similar in the two groups. The global rate of papilla identification was 66% (n = 55). The rate of deep cannulation was 58% considering all patients and 87% in the subgroup of patients in which the papilla major was identified. Cannulation was performed with standard methods in 65% of cases and with needle-knife fistulotomy in 35%. AEs occurred in 4 patients. There was no difference between duodenoscope and gastroscope in papilla identification (64% [95% CI: 51-77] vs. 71% [55-87]). Although not statistically significant, duodenoscope had a lower deep cannulation rate when considering all patients (52% [15-39] vs. 68% [7-35]) and a higher AEs rate (8% [1-15] vs. 0% [0-1]). In a multivariate analysis, the use of gastroscope significantly increased the deep cannulation rate (OR = 152.62 [2.5-9,283.6]). Conclusion: This study demonstrates that forward-viewing gastroscope is at least as effective and safe as side-viewing duodenoscope for ERCP in patients with Billroth II gastrectomy. Moreover, our study showed that gastroscope is an independent predictor of successful cannulation.

Introdução: Colangiopancreatografia retrógrada endoscópica (CPRE) em doentes submetidos previamente a gastrectomia com reconstrução Billroth II é ainda um exame desafiante. A melhor abordagem, nomeadamente o tipo de endoscópio e a técnica de canulação biliar, ainda não está definida. Objectivo: Comparar a eficácia e segurança do gastroscópio de visão frontal e do duodenoscópio de visão lateral na CPRE de doentes com gastrectomia com reconstrução Billroth II. Métodos: Conduzimos um estudo de coorte retrospectivo e unicêntrico que incluiu consecutivamente doentes com gastrectomia com reconstrução Billroth II submetidos a CPRE num centro de referência para CPRE entre 2005 e 2021. Os outcomes avaliados foram: identificação da papila, canulação biliar profunda e efeitos adversos (EAs). Regressão logística foi realizada para avaliar possíveis associações e preditores dos outcomes. Resultados: Incluímos 83 doentes com uma idade mediana de 73 (IIQ 65­81) anos. A CPRE foi realizada usando duodenoscópio em 52 doentes e usando o gastroscópio de visão frontal em 31 doentes. As características dos doentes foram semelhantes entre os dois grupos. A taxa global de identificação da papila foi de 66% (n = 55). A taxa de canulação profunda foi de 58% considerando todos os doentes e de 87% considerando apenas o subgrupo de doentes nos quais a papila major foi identificada. A canulação foi realizada usando métodos convencionais em 65% e usando fistulotomia com faca em 35% dos doentes. EAs ocorreram em 4 doentes. Não houve diferenças entre duodenoscópio e gastroscópio relativamente à identificação da papila [64% (95% CI: 51­77) vs 71% (55­87)]. Apesar de estatisticamente não significativo, o uso de duodenoscópio teve uma menor taxa de canulação profunda quando considerados todos os doentes [52% (15­39) vs 68% (7­35)] e uma maior taxa de EAs [8% (1­15) vs 0% (0­1)]. Na regressão logística, o uso de gastroscópio significativamente aumentou a taxa de canulação profunda [OR = 152.62 (2.5­9,283.6)]. Conclusão: Este estudo demonstra que o uso de gastroscópio de visão frontal é pelo menos igualmente eficaz e seguro ao duodenoscópio na CPRE de doentes com gastrectomia com reconstrução Billroth II. Para além disso, o nosso estudo demonstrou que o uso de gastroscópio é um predictor independente para canulação.

Afferent Loop Syndrome as Second Presentation of Gastric Outlet Obstruction in Patient With Billroth II Anatomy.

Afferent loop syndrome can result from both benign and malignant strictures of the biliary limbs of patients with surgically altered anatomy. Afflicted patients accumulate intestinal and pancreaticobiliary secretions, which leads to bowel distention and pain. We describe the endoscopic management of a 52-year-old woman with a history of Billroth II gastrojejunostomy due to gastric cancer who developed malignant gastric outlet obstruction and subsequently malignant afferent loop syndrome, using lumen-apposing metal stents.

Laparoscopic-assisted robotic distal gastrectomy for gastric cancer by Billroth II reconstruction.

BACKGROUND: There are several reconstructions in distal gastrectomy for gastric cancer, and there is no clear definition regarding the method selection. The optimal reconstruction is likely to vary according to the surgical setting, and the optimal reconstruction for robotic distal gastrectomy is urgently needed. In addition, as robotic gastrectomy is getting popular, cost and operative time are pressing issues of robotic gastrectomy. METHODS: Gastrojejunostomy was planned with Billroth II reconstruction using a linear stapler arranged specifically for a robotic approach. After firing the stapler, the common insertion orifice of the stapler was closed using a 30 cm long non-absorbable barbed suture, and continuously, the afferent loop of the jejunum was lifted to the stomach with the same barbed suture. In addition, we introduced laparoscopic-assisted robotic gastrectomy, using extracorporeally inserted laparoscopic devices from the assistant port. Scissors, clips, and linear staplers were all laparoscopic tools inserted extracorporeally. RESULTS: Twenty-one gastric cancer patients underwent laparoscopic-assisted robotic distal gastrectomy by Billroth II reconstruction with our modifications. There were no anastomosis-related complications such as leakage, stenosis, or bleeding. There were 2 cases of aspiration pneumonia (Clavien-Dindo grade 2), 1 case of pancreatic juice leakage (grade 3a), and 1 case of delayed gastric emptying (grade 1). CONCLUSION: We successfully arranged Billroth II reconstruction for robotic distal gastrectomy with fewer operative and postoperative complications. Laparoscopic-assisted robotic gastrectomy using extracorporeally inserted devices, and continuous suturing using a barbed suture will reduce the time and cost of robotic gastrectomy.

Comparison of endoscopic retrograde cholangiopancreatography outcomes between cap-fitted forward and side viewing endoscopes in patients with Billroth II anastomosis.

BACKGROUND: There have been no previous studies that directly compared outcomes between cap-fitted forward-viewing and side viewing endoscopes (SE). This study aimed to compare the technical success rate and occurrence of adverse events between the side viewing and cap-fitted forward-viewing endoscope (CE) groups among patients with Billroth II anatomy who underwent ERCP. METHODS: The medical records of patients with a previous history of subtotal gastrectomy using Billroth II reconstruction who underwent ERCP at Yeungnam University Hospital between January 2004 and December 2020 were reviewed retrospectively. The patients were divided into CE and SE group. Propensity score matching analysis was performed to minimize selection bias. RESULTS: Propensity score matching resulted in 55 matched pairs for further analysis. Patients' characteristics were comparable in the matched cohorts. Final success rate of selective bile duct cannulation was not significantly different between the SE and CE groups (98.2% vs. 94.5%, p = 0.308). The complete CBD stone removal rate in CBD stone and successful biliary drainage rate in malignant biliary obstruction were not significantly different between the two groups. The rate of total ERCP-related adverse events was higher in the CE group than in the SE group, but the difference was not statistically significant (10.9% vs. 7.3%, p = 0.507). Among adverse events, the rate of post-ERCP pancreatitis showed higher tendency in the CE group than in the SE group (10.9% vs. 5.5%, p = 0.297). CONCLUSION: In conclusion, CE seems to be equally effective as SE for ERCP in patients with Billroth II anatomy. However, attention should be paid to development of post ERCP complications, especially pancreatitis, when performed by CE.

[Reconstruction and functional results after gastric resection]. / Rekonstruktionen und funktionelle Ergebnisse nach Magenresektion.

Depending on the extent of gastric resection, namely total, proximal or distal gastrectomy, different methods of reconstruction are available. These reconstructive procedures have not changed with the implementation of minimally invasive or robotic techniques in general but the spectrum of possible anastomotic techniques has been substantially expanded. Functional, in particular nutritional disorders with subsequent impairment of the health-related quality of life, are often diagnosed after gastric resections. The partial preservation of a gastric reservoir has a positive impact on the extent of these disorders. After total gastrectomy, the placement of a jejunal pouch significantly reduces the incidence of postoperative dumping symptoms. Following proximal gastrectomy, double-tract reconstruction offers certain functional advantages as compared to the simple Roux­Y reconstruction. In Germany, these reconstructive techniques are only used to a low extent and should be include in the repertoire of oncological gastric surgery with appropriate indications.

Does the addition of Braun anastomosis to Billroth II reconstruction on laparoscopic-assisted distal gastrectomy benefit patients?

BACKGROUND: Operation is the primary therapeutic option for patients with distal gastrectomy. Braun anastomosis is usually performed after Billroth II reconstruction, which is wildly applied on distal gastrectomy because it is believed to benefit patients. However, studies are needed to confirm that. AIM: To identify whether the addition of Braun anastomosis to Billroth II reconstruction on laparoscopy-assisted distal gastrectomy benefits patients. METHODS: A total of 143 patients with gastric cancer underwent laparoscopy-assisted distal gastrectomy at Centre 1 of PLA general hospital between January 2015 and December 2019. Clinical data of the patients were collected, and 93 of the 143 patients were followed up. These 93 patients were divided into two groups: Group 1 (Billroth II reconstruction, 33 patients); and Group 2 (Billroth II reconstruction combined with Braun anastomosis, 60 patients). Postoperative complication follow-up data and relevant clinical data were compared between the two groups. RESULTS: There were no significant differences between Group 1 and Group 2 in postoperative complications (6.1% vs 6.7%, P = 0.679), anal exhaust time or blood loss. The follow-up prevalence of reflux gastritis indicated no significant difference between Group 1 and Group 2 (68.2% vs 51.7%, P = 0.109). The follow-up European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 scores revealed no evident difference between Group 1 and Group 2 as well. Group 1 had a shorter operating time than Group 2 on average (234.6 min vs 262.0 min, P = 0.017). CONCLUSION: Combined with Billroth II reconstruction, Braun anastomosis has been applied due to its ability to reduce the prevalence of reflux gastritis. Whereas in this study, the prevalence of reflux gastritis showed no significant difference, leading to a conclusion that under the circumstance of Braun anastomosis costing more time and more money, simple Billroth II reconstruction should be widely applied.

Comparison of gastric-jejunum pouch anastomosis and Billroth-II reconstructions after distal gastrectomy: a propensity score matching analysis.

Purpose: Our study aimed to make a propensity score matching (PSM) analysis on the clinical application of gastric-jejunum pouch anastomosis (GJPA) and Billroth-II anastomosis after distal gastrectomy. Methods: We collected clinical data from 249 patients who received distal gastrectomy from January 2016 to July 2020. According to the reconstruction method used, all patients were divided into the Billroth-II group and the GJPA group. Clinical data and operation complications were analyzed. Results: The clinical characteristics of the 2 groups were comparable after PSM. In the Billroth-II group, the incidence rate of delayed gastric emptying was higher than that in the GJPA group. Fewer patients suffered reflux gastritis in the GJPA group. The RGB (residue, gastritis, and bile) scores related to the severity of bile reflux into the remnant stomach, gastritis, and residue were higher in the Billroth-II group. Postoperative nutritional status and Visick classification demonstrated that postoperative subjective feelings in the GJPA group were improved significantly. Conclusion: The application of GJPA in reconstruction after distal gastrectomy is safe, economical, and reliable. This reconstruction improved the quality of life of patients. It is worth popularizing widely in clinical settings.

Comparison between laparoscopic uncut Roux-en-Y and Billroth II with Braun anastomosis after distal gastrectomy: A meta-analysis.

BACKGROUND: Conventional Billroth II (BII) anastomosis after laparoscopic distal gastrectomy (LDG) for gastric cancer (GC) is associated with bile reflux gastritis, and Roux-en-Y anastomosis is associated with Roux-Y stasis syndrome (RSS). The uncut Roux-en-Y (URY) gastrojejunostomy reduces these complications by blocking the entry of bile and pancreatic juice into the residual stomach and preserving the impulse originating from the duodenum, while BII with Braun (BB) anastomosis reduces the postoperative biliary reflux without RSS. Therefore, the purpose of this study was to compare the efficacy and safety of laparoscopic URY with BB anastomosis in patients with GC who underwent radical distal gastrectomy. AIM: To evaluate the value of URY in patients with GC. METHODS: PubMed, Embase, Web of Science, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang, Chinese Biomedical Database, and VIP Database for Chinese Technical Periodicals (VIP) were used to search relevant studies published from January 1994 to August 18, 2021. The following databases were also used in our search: Clinicaltrials.gov, Data Archiving and Networked Services, the World Health Organization International Clinical Trials Registry Platform Search Portal (https://www.who.int/clinical-trials-registry-platform/the-ictrp-search-portal), the reference lists of articles and relevant conference proceedings in August 2021. In addition, we conducted a relevant search by Reference Citation Analysis (RCA) (https://www.referencecitationanalysis.com). We cited high-quality references using its results analysis functionality. The methodological quality of the eligible randomized clinical trials (RCTs) was evaluated using the Cochrane Risk of Bias Tool, and the non-RCTs were evaluated using the Newcastle-Ottawa scale. Statistical analyses were performed using Review Manager (Version 5.4). RESULTS: Eight studies involving 704 patients were included in this meta-analysis. The incidence of reflux gastritis [odds ratio = 0.07, 95% confidence interval (CI): 0.03-0.19, P < 0.00001] was significantly lower in the URY group than in the BB group. The pH of the postoperative gastric fluid was lower in the URY group than in the BB group at 1 d [mean difference (MD) = -2.03, 95%CI: (-2.73)-(-1.32), P < 0.00001] and 3 d [MD = -2.03, 95%CI: (-2.57)-(-2.03), P < 0.00001] after the operation. However, no significant difference in all the intraoperative outcomes was found between the two groups. CONCLUSION: This work suggests that URY is superior to BB in gastrointestinal reconstruction after LDG when considering postoperative outcomes.

An Exceptionally Rare Primary Epithelioid Rhabdomyosarcomas of the Stomach: A Case Report.

Rhabdomyosarcoma (RMS) is a common soft tissue tumor in adults, but RMS's causes and risk factors are unknown. We present a case of a 62-year-old man with RMS who presented with feelings of fullness after meals and vomiting for the previous five months with anorexia and weight loss for four months. He reported feeling a rolling mass in his belly that moves from left to right. He was initially diagnosed with gastric outlet obstruction due to stomach carcinoma. During the surgical operation, we noted the gross appearance was unlike typical adenocarcinoma or lymphoma of the stomach. Histopathological evaluation of the specimen confirmed a diagnosis of primary epithelial RMS of the stomach. When treating RMS, expertise in immunohistochemistry, molecular biology, genetics, or ultrastructure may be necessary. Information on the appropriate laboratory investigations and management protocol is limited, but an early diagnosis can change the course of treatment and improve patient outcomes.
