Abstract

Introduction: Biliary stricture is a common disease in Vietnam. However, there were very few authors who have researched about the results of biliary stricture’s treatment. The purpose of this study was to evaluate the results of biliary dilation by balloon dilator via flexible cholangioscopy for treatment of primary bile duct stricture. Patient and methods: Descriptive, prospective, non-controlled research on patients with biliary stones and primary bile duct strictures treated by balloon dilator via flexible cholangioscopy at the Abdominal surgery centre - Military hospital 103 from July 2021 to July 2024. Results: Mean age: 60.1 ± 14.1; Female/male ratio = 1.69/1; 75.8% of patients had the history of biliary stones. Most biliary strictures were in 1 position (90.3%). The strictures mostly were 2mm - 5mm long (53,6%), 3-<4mm in diameter (52.2%) and were all benign. Surgical methods were choledochotomy with intraoperative flexible cholangioscopy (90.3%) and percutaneous flexible cholangioscopy (9.7%). Biliary strictures were taken by balloon dilation; then, biliary-cutaneous stents were placed in 64.5% of cases. Intraoperative complications: 16.1%, postoperative complications: 12.9%. The rate of stone stricture clearance after surgery was 87.1%. Rechecked at 1, 3, and 6 months after operation, the ratio of recurrent biliary strictures was 1.9%, 7.4%, and 11.1%, respectively. Conclusions: Biliary dilation by balloon dilator via flexible cholangioscopy was a safe and effective method for the treatment of primary bile duct strictures in biliary stones’ patients.
