Abstract

Background and Aim: Endoscopic papillary balloon dilatation (EPBD) and endoscopic sphincterotomy (EST) are two common nonsurgical treatments endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis. The aim of this study was to compare the efficacy and safety of EPBD and EST in the treatment for choledocholithiasis, confining the analysis to work reported in the last decade.

Methods: The rate of overall postoperative complications was chosen as the primary outcome, and 10 other outcomes were secondary outcomes. Relative risk (RR) or Peto odds ratio (OR) were computed as the measures of pooled effects. We planned sensitivity analyses a priori for examining the change in robustness of the sensitivity to excluding studies with some inappropriate objects, technique defects or without full-text acquisition.

Results: For complete stone removal, EPBD was similar to EST (95% vs. 96%, P = 0.36) and overall postoperative complications (14.0% vs. 11.7%, P = 0.53). The incidence of post-ERCP cholangitis (2.5% vs. 1.8%, P = 0.40), basket impaction (0.9% vs. 0%, P = 0.16) and perforation (0.0% vs. 0.4%, P = 0.17) were equivalent between EPBD and EST. On the other hand, EPBD caused more post-ERCP pancreatitis (PEP) (9.4% vs. 3.3%, P < 0.00001), but less hemorrhage (0.1% vs. 4.2%, P < 0.00001). People undergoing EPBD required more use of endoscopic mechanical lithotripsy (35.0% vs. 26.2%, P = 0.0004). The results of sensitivity analyses showed no substantial change.

Conclusion: EPBD is comparable to EST for stone extraction, though it requires more endoscopic mechanical lithotripsy (EML). EPBD may outweigh EST for patients with coagulopathy; however, it may cause more PEP.
