Abstract

Background and aims: The obesity epidemic has led to increased use of Roux-en-Y gastric bypass (RYGB). These patients have an increased incidence of pancreaticobiliary diseases, yet standard ERCP is not possible because of surgically altered gastroduodenal anatomy. Laparoscopy-assisted ERCP (LA-ERCP) has been proposed as an option, but supporting data are derived from single-center small case series. Therefore, we conducted a large multicenter study to evaluate the feasibility, safety, and outcomes of LA-ERCP.

Methods: This is a retrospective cohort study of adult patients with RYGB who underwent LA-ERCP in 34 centers. Data on demographics, indications, procedure success, and adverse events were collected. Procedure success was defined when all the following were achieved: reaching the papilla, cannulating the desired duct, and providing endoscopic therapy as clinically indicated.

Results: A total of 579 patients (median age, 51; 84% women) were included. Indication for LA-ERCP was biliary in 89%, pancreatic in 8%, and both in 3%. Procedure success was achieved in 98%. Median total procedure time was 152 minutes (interquartile range [IQR], 109-210), with a median ERCP time of 40 minutes (IQR, 28-56). Median hospital stay was 2 days (IQR, 1-3). Adverse events were 18% (laparoscopy related, 10%; ERCP related, 7%; both, 1%) with the clear majority (92%) classified as mild/moderate, whereas 8% were severe and 1 death occurred.

Conclusions: Our large multicenter study indicates that LA-ERCP in patients with RYGB is feasible with a high procedure success rate comparable with that of standard ERCP in patients with normal anatomy. The ERCP-related adverse events rate is comparable with conventional ERCP, but the overall adverse event rate was higher because of the added laparoscopy-related events.
