SP6.1.7 Meta-analysis of procedural outcomes of laparoscopic-assisted endoscopic retrograde cholangiopancreatography in patients with previous Roux-en-Y gastric bypass surgery

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