Abstract

Introduction: Treatment of pancreaticobiliary pathology following Roux-en-Y gastric bypass (RYGB) poses significant technical challenges. Laparoscopic-assisted endoscopic retrograde cholangiopancreatography (LA-ERCP) can overcome those anatomical hurdles, allowing access to the papilla. Our aims were to analyze our 12-year institutional outcomes and determine the learning curve for LA-ERCP. Methods: A retrospective review of cases between 2007 and 2019 at a high-volume pancreatobiliary unit was performed. Logistic regression was used to identify predictors of specific outcomes. To identify the learning curve, CUSUM analyses and innovative methods for standardizing the surgeon’s timelines were performed. Results: 131 patients underwent LA-ERCP (median age 60, 81% females) by 17 surgeons and 10 gastroenterologists. Cannulation of the papilla was achieved in all cases. Indications were choledocholithiasis (78%), Sphincter of Oddi dysfunction/Papillary stenosis (18%), management of bile leak (2%) and stenting/biopsy of malignant strictures (2%). Median total, surgical and ERCP times were 180, 128 and 48 min, respectively, and 47% underwent concomitant cholecystectomy. Surgical site infection developed in 9.2% and post-ERCP pancreatitis in 3.8%. Logistic regression revealed multiple abdominal operations and magnitude of BMI decrease (between RYGB and LA-ERCP) to be predictive of conversion to open approach. CUSUM analysis of operative time demonstrated a learning curve at case 27 for the surgical team and case 9 for the gastroenterology team. On binary cut analysis, 3–5 cases per surgeon were needed to optimize operative metrics. Conclusion: LA-ERCP is associated with high success rates and low adverse events. We identify outcome benchmarks and a learning curve for new adopters of this increasingly performed procedure.
