Abstract

OBJECTIVE:

Endoscopic sphincterotomy plus large-balloon dilatation (ESLBD) has an efficacy equal to or higher than that of endoscopic sphincterotomy alone for biliary lithiasis extractions. Our purpose was to evaluate the feasibility, efficacy and morbidity of large-balloon dilatation of the sphincter of Oddi after sphincterotomy or infundibulotomy for large or multiple common bile duct stones.

MATERIAL AND METHODS:

Retrospective analysis.

RESULTS:

A total of 64 ESLBD procedures were performed in 62 patients: 57 after sphincterotomy and 7 after infundibulotomy. The feasibility was 100%, and full clearance of the common bile duct was achieved in a single session without using mechanical lithotripsy in 95.3% of cases. Short-term complications were observed in 9 patients (14%). There were no perforations. The most frequent complication was delayed bleeding (7.8%). There was no significant difference of overall complications after sphincterotomy or after infundibulotomy (12.3% vs. 28.6%, p = 0.25). The incidence of acute pancreatitis was significantly higher after infundibulotomy than after sphincterotomy (28.6% vs. 0%, p = 0.01).

CONCLUSIONS:

ESLBD after endoscopic sphincterotomy or infundibulotomy is a simple, reproducible and effective technique, associated with a low morbidity rate and helps in avoiding mechanical lithotripsy in 95.3% of cases for the endoscopic extraction of large or multiple common bile duct stones.
