Rationale and Trial Protocol for a Double-Blinded Randomized Controlled Trial to assess the Impact of a Concomitant Crural Repair during Laparoscopic Sleeve Gastrectomy in Patients with a Lax Gastroesophageal Junction without Frank Hiatal Hernia (REPAIR trial protocol).

INTRODUCTION: Laparoscopic sleeve gastrectomy (LSG) is associated with postoperative gastroesophageal reflux disease (GERD) and erosive esophagitis (EE). The role of crural repair during LSG is still controversial. The preoperative laxity of the gastroesophageal junction (GEJ), graded by the Hill's classification, is more predictive for postoperative GERD and EE after LSG than the presence of a hiatal hernia seen on endoscopy. Thus, the authors hypothesize that a concomitant crural repair in a specific subgroup of patients with a lax GEJ (Hill's III) may reduce the incidence of postoperative GERD and EE. METHODS: A double-blinded, randomized controlled trial of patients with Hill's III GEJ undergoing LSG will be randomized to a concomitant crural repair (experimental) versus LSG alone (control). Primary outcome measures will be presence of EE at 1-year. Secondary outcome measures will include proton pump inhibitor use, postoperative complications, operative time, blood loss, quality of life, GERD and gastrointestinal symptoms. CONCLUSION: Conflicting crural repair results may be explained by differences in preoperative GEJ laxity. Patients with a frank hiatal hernia and patulous GEJ (Hill's IV) have a very high, while patients with an apposed GEJ (Hill's I, Hill's II) have a low incidence of postoperative GERD and EE respectively. Thus, the authors hypothesize that patients with a lax GEJ without frank hiatal hernia (Hill's III), might benefit from a crural repair. This study results can potentially highlight the clinical importance of preoperative endoscopic evaluation of the GEJ in all patients planned for LSG, to determine which subgroup patients may benefit from a crural repair.

Effectiveness of sleeve gastrectomy plus fundoplication versus sleeve gastrectomy alone for treatment of patients with severe obesity: a systematic review and meta-analysis.

BACKGROUND: Laparoscopic sleeve gastrectomy (SG) is a widely performed bariatric surgery, but it is associated with an increased risk of gastroesophageal reflux (GERD) in the long term. The addition of fundoplication to laparoscopic SG may improve lower oesophageal sphincter function and reduce postoperative GERD. OBJECTIVES: This systematic review and meta-analysis aims to compare the efficacy and safety of SG plus fundoplication (SG + F) versus SG alone for the treatment of patients with severe obesity (≥35 kg/m2). SETTING: Meta-analysis. METHODS: Three electronic databases were searched from inception until January 2023. Studies were included if they compared outcomes of SG + F versus SG in patients with severe obesity (≥35 kg/m2). The primary outcome was remission of GERD postoperatively. Secondary outcomes were the percentage of excess weight loss, percentage of total weight loss, postoperative complication rate, operative time, and length of stay. RESULTS: A total of 5 studies with 539 subjects (212 SG + F and 327 SG alone) were included. The mean preoperative body mass index was 42.6 kg/m2. SG + F achieved higher remission of GERD compared with laparoscopic SG (odds ratio [OR] = 13.13; 95% CI, 3.54-48.73; I2 = 0%). However, the percentage of total weight loss was lower in the SG + F group (mean difference [MD] = -2.75, 95% CI, -4.28 to -1.23; I2 = 0%), whereas there was no difference in the percentage of excess weight loss (MD = -0.64; 95% CI, -20.62-19.34; I2 = 83%). There were higher postoperative complications in SG + F (OR = 2.56; 95% CI, 1.12-5.87; I2 = 0%) as well. There was no difference in operative time or length of stay between the 2 groups. CONCLUSION: SG + F achieved better GERD remission but is associated with lesser weight loss and increased postoperative complications compared with SG alone. Further studies are required to ascertain the overall clinical benefit of SG + F for patients with severe obesity.

Academy of Medicine, Singapore clinical guideline on endoscopic surveillance and management of gastric premalignant lesions.

Gastric cancer (GC) has a good prognosis, if detected at an early stage. The intestinal subtype of GC follows a stepwise progression to carcinoma, which is treatable with early detection and intervention using high-quality endoscopy. Premalignant lesions and gastric epithelial polyps are commonly encountered in clinical practice. Surveillance of patients with premalignant gastric lesions may aid in early diagnosis of GC, and thus improve chances of survival. An expert professional workgroup was formed to summarise the current evidence and provide recommendations on the management of patients with gastric premalignant lesions in Singapore. Twenty-five recommendations were made to address screening and surveillance, strategies for detection and management of gastric premalignant lesions, management of gastric epithelial polyps, and pathological reporting of gastric premalignant lesions.

The Hill's Classification Is Useful to Predict the Development of Postoperative Gastroesophageal Reflux Disease and Erosive Esophagitis After Laparoscopic Sleeve Gastrectomy.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is one of the commonest bariatric procedures. However, it is associated with postoperative gastroesophageal reflux disease (GERD) and erosive esophagitis (EE). This study aims to assess the impact of various preoperative clinical and endoscopic characteristics on the development of postoperative GERD and EE. METHODS: This study is a single-institution retrospective cohort study involving all patients who underwent LSG. A univariate and multivariate analysis was performed to identify preoperative parameters that were significantly associated with the development of postoperative GERD and EE, at up to 1-year follow-up. RESULTS: At up to 1-year follow-up, out of 127 patients, only preoperative endoscopic presence of a hiatal hernia noted on axial length (p=0.024) and the Hill's classification of the gastroesophageal junction (p<0.001) were significantly associated with the development of postoperative GERD. Similarly, at 1-year follow-up endoscopy, the presence of a hiatal hernia (p=0.041) and the Hill's classification (p=0.001) were associated with postoperative EE. On the multivariate analysis, compared to patients with a Hill's I flap valve, Hill's II patients were more likely to develop postoperative GERD (OR 7.13, 95% CI: 1.69-29.98, p=0.007), and Hill's III patients were more likely to develop postoperative GERD (OR 20.84, 95% CI: 3.98-109.13, p<0.001) and EE (OR 34.49, 95% CI: 1.08-1105.36, p=0.045). All patients with Hill's IV developed postoperative GERD and EE in this study. CONCLUSION: Postoperative GERD and EE remain an important limitation following LSG. Proper preoperative assessment using the Hill's classification can help to accurately predict patients at risk of postoperative GERD and EE.

Endoscopic internal drainage with double pigtail stents for upper gastrointestinal anastomotic leaks: suitable for all cases?

BACKGROUND/AIMS: Surgeons and endoscopists have started to use endoscopically inserted double pigtail stents (DPTs) in the management of upper gastrointestinal (UGI) leaks, including UGI anastomotic leaks. We investigated our own experiences in this patient population. METHODS: From March 2017 to June 2020, 12 patients had endoscopic internal drainage of a radiologically proven anastomotic leak after UGI surgery in two tertiary UGI centers. The primary outcome measure was the time to removal of the DPTs after anastomotic healing. The secondary outcome measure was early oral feeding after DPT insertion. RESULTS: Eight of the 12 patients (67%) required only one DPT, whereas four (33%) required two DPTs. The median duration of drainage was 42 days. Two patients required surgery due to inadequate control of sepsis. Of the remaining 10 patients, nine did not require a change in DPT before anastomotic healing. Nine patients were allowed oral fluids within the 1st week and a soft diet in the 2nd week. One patient was allowed clear oral feeds on the 8th day after DPT insertion. CONCLUSION: Endoscopic internal drainage is becoming an established minimally invasive technique for controlling anastomotic leak after UGI surgery. It allows for early oral nutritional feeding and minimizes discomfort from conventional external drainage.

Kamikawa Double-Flap Reconstruction After Minimally Invasive Ivor-Lewis Esophagectomy.

Despite the high incidence of reflux esophagitis, there are few reports of antireflux modifications for minimally invasive Ivor-Lewis esophagectomy. We present the case of a 63-year-old man with mid-thoracic esophageal squamous cell carcinoma who underwent minimally invasive Ivor-Lewis esophagectomy after neoadjuvant chemoradiotherapy. Laparoscopic dissection, gastric tube creation, and mobilization was performed. Thoracoscopic esophageal dissection, subcarinal, paraesophageal and diaphragmatic lymphadenectomy were performed, followed by esophagogastric anastomosis with double seromuscular flap reconstruction to recreate the lower esophageal sphincter. The operation was completed in 618 minutes with 200 mL blood loss and the patient recovered uneventfully. A morphologic sphincter was seen on postoperative contrast study.

Laparoscopic D2 total gastrectomy and en-mass splenectomy and distal pancreatectomy for locally advanced proximal gastric cancer.

BACKGROUND: Safety and efficacy of laparoscopy surgery in locally Advanced Gastric Cancers (AGC) have not been proven by randomized control trials. Therefore, standard of care for AGC is still open surgery. Here, we are presenting a 64-year-old female with proximal gastric adenocarcinoma (close to cardio-oesophageal junction) adherent to tail of pancreas, who underwent D2 total gastrectomy en-mass distal pancreatectomy and splenectomy. METHODS: Five ports are entered into the peritoneal cavity (Three 10-12 mm and two 5 mm ports). Another 5 mm stab incision is made in the epigastrium for Nathanson Liver retractor. Standard D2 Gastrectomy was performed with en-mass removal of the spleen and body and tail of the pancreas. Roux-en-Y oesophago-jejunostomy (Hand sewn) and Jejuno-Jejunostomy reconstruction were performed laparoscopically. Hereby, we present a video of the above procedure. RESULTS: Total Operating time was 235 min. Post-operatively the patient was able to mobilize independently. Total Parenteral Nutrition (TPN) was started and continued until post-operative day (POD) 7 once gastrografin test and blue dye test both showed no anastomotic leak. Patient started on oral feeding and was discharged home well on POD 9. Histology showed poorly differentiated adenocarcinoma with pT3N3b (17 nodes out of 62 positive). CONCLUSION: Although laparoscopic D2 gastrectomy and en-mass distal pancreatectomy and splenectomy are feasible and safe in advanced gastric carcinoma, its oncological value has yet to be determined.
