Objective: To evaluate the results of biliary dilatation and stone removal via flexible cholangioscopy for the treatment main bile duct strictures (BS) and stones.
Patients and methods: Descriptive, prospective research on patients with BS and stones treated by biliary dilatation and stone removal via flexible cholangioscopy at Military hospital 103 from July 2021 to July 2024.
Results: Research on 62 patients. Mean age: 60.1 ± 14.1; Female/male ratio = 1.69/1; Multiple stones were the majority (79%), both choledocholithiasis and hepatolithiasis (83.9%). BS were mostly in one location (90.3%), intrahepatic strictures (88.7%), and were all benign. Surgical methods were choledochotomy with intraoperative cholangioscopy (90.3%) and percutaneous cholangioscopy (9.7%). Stone removal was taken by baskets, electrohydraulic or/and holmium laser lithotripsy. Biliary stricture was taken by balloon dilatation; then, biliary-cutaneous stents were placed in 64.5% of cases. Intraoperative complications: 16.1%, postoperative complications: 12.9%. The rate of stone clearance and stricture dilatation after surgery: 83.9% and 87.1%. Rechecked at 1, 3 and 6 months after operation, the ratio of recurrent BS and stones was 1.9%, 7.4%, 11.1% and 0%, 0%, 5.8%, respectively.
Conclusion: Stone removal and stricture dilatation by flexible cholangioscopy was a safe and effective method for the treatment of main bile duct strictures and stones.
