Incidence and risk factors for early gastrojejunostomy anastomotic stricture requiring endoscopic intervention following laparoscopic Roux-en-Y gastric bypass: a MBSAQIP analysis

Background and Aims. The insertion of the guidewires (GWs) into the pancreatic duct is technically difficult, and there is a risk of post-ERCP pancreatitis (PEP). The aim of this study was to evaluate the safety and efficacy of a small J-tipped guidewire for pancreatic duct endoscopic intervention. Methods. This single-site retrospective study was conducted to assess the procedural success rate and adverse events of endoscopic transpapillary interventions to the pancreatic duct in 114 cases using the small J-tipped GW and 180 cases using the angle-tipped GW. Results. The procedural success rate was significantly higher in the small J-tipped GW group compared with that in the angle-tipped GW group (76% versus 47%, P < 0.001). The procedural success-related factors were chronic pancreatitis (OR 0.43, 95% CI 0.22–0.82, P = 0.01), flexion angle of the pancreatic duct < 90° (OR 0.50, 95% CI 0.30–0.80, P = 0.01), and use of the small J-tipped GW (OR 4.63, 95% CI 2.61–8.20, P < 0.001). The rates of total post-ERCP pancreatitis were significantly lower in the small J-tipped GW group compared with that in the angle-tipped GW group (3.5% versus 12.2%, P = 0.01). Multivariate analysis of pancreatitis risk factors indicated that only the use of the small J-tipped GW was a factor in decreasing the risk of developing pancreatitis (OR 0.12, 95% CI 0.09–0.85, P = 0.02). Conclusions. Small J-tipped GWs increase the success rate of the pancreatic duct endoscopic intervention as well as a reduced risk of developing postoperative pancreatitis.

Abstract Background Patients who have undergone bariatric surgery are at risk for subsequent cholecystectomy. We aimed to identify risk factors for cholecystectomy after laparoscopic Roux-en-Y gastric bypass (LRYGB). Methods We conducted a retrospective case-control study of patients who underwent LRYGB between 2013 and 2015. Cases underwent cholecystectomy because of biliary symptoms after LRYGB. For each case, two controls were selected without subsequent cholecystectomy. Logistic regression analyses were used to identify risk factors. Results Between 2013 and 2015, 1780 primary LRYGBs were performed. We identified 233 (13.1%) cases who had undergone cholecystectomy after a median (IQR) of 12 (8–17) months, and 466 controls. Female gender (OR (95% CI) 1.83 (1.06–3.17)), Caucasian ethnicity (OR (95% CI) 1.82 (1.10–3.02)), higher percent total weight loss (%TWL) at 12 months (OR (95% CI) 1.06 (1.04–1.09)), and preoperative pain syndrome (OR (95% CI) 2.72 (1.43–5.18)) were significantly associated with an increased risk for cholecystectomy. Older age (OR (95% CI) 0.98 (0.96–0.99)) and preoperative statin use were associated with a reduced risk (OR (95% CI) 0.56 (0.31–1.00)). A dose-effect relationship was found between the intensity of preoperative statin and risk for cholecystectomy. Conclusions In our study, higher %TWL and preoperative pain syndrome were associated with an increased risk for cholecystectomy besides the traditional risk factors female gender and Caucasian ethnicity. These factors can be used to identify high-risk patients, who might benefit from preventive measures. Whether statins can protect bariatric patients from developing gallstones should be investigated prospectively.
