PURPOSE: To report the authors' experience with percutaneous papillary balloon dilation for extrahepatic bile duct stone clearance to the duodenum in 300 patients.
MATERIALS AND METHODS: During a 16-year period, 300 patients with extrahepatic bile duct stones who underwent papillary balloon dilation were retrospectively evaluated. Two hundred eighty-six patients with retained extrahepatic bile duct stones were treated through a postoperative drain placed during cholecystectomy; 245 patients were treated through a T-tube route and 41 through a transcystic approach. In the remaining 14 patients, the procedure was performed through a newly created percutaneous transhepatic route. Success rates, technical features, reasons for failure, and complications were evaluated.
RESULTS: Biliary duct stone removal after papillary dilation was successful in 288 patients (96%). In 244 patients, the procedure was successfully completed on the first attempt. Forty-three patients needed two sessions, and in one patient it took three sessions. Stone diameters ranged from 4 mm to 18 mm (mean, 8 mm). Two hundred fourteen patients had four or fewer stones (mean, 2.3), and 86 patients had more than four (mean, 8.8; range, 5-25). Two patients required surgical intervention after loss of transcystic drainage, with subsequent development of peritonitis. During the follow-up period (mean, 26.6 months), no clinical or laboratory abnormalities were observed.
CONCLUSIONS: Percutaneous antegrade papillary balloon dilation and stone clearance is a safe and effective tool in removing common bile duct stones. Some technical issues should be considered to achieve complete stone removal while minimizing the incidence of complications.
