Abstract
Purpose: Laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography (LAERCP) is an alternative for the anatomically challenging conventional ERCP in patients with a Roux-en-Y gastric bypass (RYGB) as it allows access to the biliary tree via the gastric remnant. We investigated the efficacy and safety of LAERCP. Material and Methods: We retrospectively reviewed all charts from RYGB patients who underwent a LAERCP between January 2009 and August 2019 in a non-academic referral center for bariatric surgery. Patients who underwent pancreatic therapy were excluded. We collected demographic, clinical, and outcome data. An adverse event was defined as any complaint related to the LAERCP up to 30 days after the procedure and graded according to the ASGE lexicon. Results: We identified 100 LAERCP in 86 patients with RYGB (70% female, median age 54 years). Same-session cholecystectomy was performed in 35 LAERCP (35%). The papilla of Vater was visualized in 100% of LAERCP with a therapeutic success rate of 94%. Stone extraction succeeded in 88.8% and sphincterotomy was performed in 96.7%. We identified 30 adverse events in 28 procedures, of which eight endoscopy-related, 14 laparoscopy-related, and eight non-specified (f.i. fever, allergic reaction). In total, six severe adverse events were reported concerning post-ERCP pancreatitis (n = 2), laparoscopy-related hemorrhage (n = 1), abscess (n = 1), shock (n = 1), and pneumonia (n = 1). No patient died due to LAERCP. Conclusion: LAERCP is an effective and relatively safe procedure for biliary diseases in patients with RYGB.
