Abstract

PURPOSE
The residual intrahepatic stones with biliary strictures are difficult to remove percutaneously via T-tube tract after surgery in patients with recurrent pyogenic cholangitis. We evaluated the effectiveness of percutaneous balloon dilatation of benign biliary strictures.
MATERIALS AND METHODS
The balloon dilatations with 6-12mm angioplasty balloon catheter and stone extractions were performed via a T-tube tract after surgical treatment in 15 patients with recurrent pyogenic cholangitis. The balloons were inflated for 3-4minutes under 5 atm. until disappearance of waist of the stricture site, from one to seven session. After balloon dilatation, residual stones were extracted with saline irrigation or stone basket.
RESULTS
Among total 42 strictures, the balloon dilatation was succesful in 27 strictures(64.3%), partially successful in 12 strictures(28.6%), and failed in three strictures(7.1%). Single or central biliary strictures were dilated easily rather than multiple ductal strictures. Of 26 sites with residual intrahepatic stones, stone extraction was complete in 17 sites(65.4%), incomplete in seven sites(26.9%) due to impacted or large stone and acute ductal angulation, and failed in two sites(7.7%).
CONCLUSION
Percutaneous balloon dilatation of benign biliary strictures is an effective procedure for extraction of residual intrahepatic stones associated with recurrent pyogenic cholangitis.
