Once a common bariatric procedure, laparoscopic adjustable gastric band (LAGB) is more frequently the subject of conversion procedures, particularly to laparoscopic sleeve gastrectomy (LSG), due to failure of weight loss, weight regain, and band intolerance. Staple line reinforcement (SLR) in primary LSG has been studied extensively, but has not been evaluated in revision procedures. The aim of this study is to investigate commonly used SLR techniques and their effects on morbidity and mortality in single-stage bands converted to sleeves. The Metabolic and Bariatric Surgery Accreditation Quality and Improvement Program (MBSAQIP) Participant Use Data Files (PUF) for 2015–2016 were utilized to assess data for single-stage bands converted to sleeves based on CPT codes, and records were stratified by technique of staple line reinforcement. The database contained all the defined variables utilized for analysis with the exception of leak rate and overall morbidity, which had to be derived. Thirty-day outcomes were analyzed using multiple bivariate analyses and Bonferroni corrections were applied. Of the 6,286 patients who underwent single-stage bands converted to sleeves for whom SLR data is available, 56.9% of surgeons utilized SLR only, 21.3% chose no reinforcement technique (No SLR), 13.4% chose SLR plus over-sewing of the staple line (SLR+OSL), and 8.4% chose OSL alone. There were no statistically significant differences in rates of death, reoperation, readmission, reintervention, number of bleeding events, and staple line leaks across groups. Choice of SLR does not affect number of bleeding events or staple line leak rate.

Background Anastomotic leaks and strictures of the gastrojejunostomy are a cause of major morbidity following laparoscopic Roux-en-Y gastric bypass (LRYGB). Reported rates of leaks vary between 0 and 5.2 %. This has led bariatric surgeons to use a variety of intraoperative methods to detect incompetent suture lines. The aim of the study was to evaluate the role of intraoperative endoscopy in reducing the rate of postoperative anastomotic complications. The setting of this study is in a community teaching hospital. Methods Medical records of 2,311 patients who underwent a LRYGB from 2002 to 2011 were retrospectively reviewed utilizing the hospitals’ bariatric surgery database. Demographics, weight, body mass index, intraoperative endoscopy results, and postoperative outcomes within 90 days after surgery were analyzed. Results Endoscopy was attempted in 2,311 patients and completed in 2,308 (99.9 %). Intraoperative leak was detected in 80 (3.5 %) patients; suture line was reinforced in 46 patients (2 %), while in the other 34 patients the leak was transient at only high insufflation pressure. Postoperative clinical leaks were detected in four cases (0.2 %) two of which had initial leaks intraoperatively. In two cases, the anastomosis was too tight and required reconstruction. Twenty-five patients (1.1 %) developed early postoperative strictures requiring endoscopic dilatation within 90 days. Three patients (0.1 %) had iatrogenic injury at the time of intraoperative endoscopy, all three healed without delayed morbidity. Conclusions The routine use of intraoperative endoscopy in LRYGB with the linear stapler anastomosis technique is associated with a complication/failure rate of 0.3 % and low gastrojejunostomy-related morbidity after LRYGB within 90 days (leak rate of 0.2 % and stricture rate of 1.1 %).
