Purpose
To investigate the procedural outcomes of laparoscopic-assisted endoscopic retrograde cholangiopancreatography (ERCP) in patients with previous Roux-en-Y gastric bypass (RYGB) surgery.
Materials and Methods
We performed a systematic review in accordance with PRISMA statement standards to identify all studies reporting procedural outcomes of laparoscopic-assisted ERCP in patients with previous RYGB. The ROBINS-I tool was used to assess the risk of bias of the included studies. Fixed-effect and random-effects models were applied to calculate pooled outcome data.
Results
A total of 17 case series, enrolling 256 patients, were included. The mean age of included patients was 49. The mean procedure time was 137 min (95% CI 102–172). In terms of procedural success rates, the overall technical success was 95.3% (95% CI 92.5–97.5, I2 = 0%), papillary access success was 95.3% (95% CI 92.5–97.5, I2 = 0%), cannulation success was 95.3% (95% CI 92.5–97.5, I2 = 0%), sphincterotomy success was 96.1% (95% CI 93.5–98.1, I2 = 0%), and stone removal success was 95.9% (95% CI 92.4–98.4, I2 = 0%). Conversion to open was required in 4.7% (95% CI 2.5–7.6, I2 = 0%). In terms of complications, pancreatitis occurred in 4.7% (95% CI 2.3–8, I2 = 17%), cholangitis in 1.7% (95% CI 0.5–3.6, I2 = 0%), and perforation in 3.7% (95% CI 1.8–6.3, I2 = 0%). The length of hospital stay was 3 days (95% CI 2–4).
Conclusions
Laparoscopic-assisted ERCP seems to be feasible, effective, and a safe method to access the biliary tract in patients with previous RYGB as indicated by high technical success rates and low complication rates. There is a need for comparative evidence regarding outcomes of laparoscopic ERCP in comparison with alternative treatment options.
