Abstract

Objectives: To investigate the characteristics of biliary stricture through flexible cholangioscopy in patients with main bile duct stones at Military Hospital 103. Patient and methods: Descriptive, prospective, non-controlled research on patients with primary bile duct stones with biliary stricture treated by flexible cholangioscopy at the Abdominal surgery centre - Military hospital 103 from July 2021 to July 2024.  Results: Researched on 62 patients. Mean age: 60.1 ± 14.1; Female/male ratio = 1.69/1; 75.8% of patients had the history of biliary stone. Of these, 54.8% had biliary operations. Cholangioscopy detected 100% of stricture locations, so it was outstanding other diagnostic imaging methods. Most biliary stricture were in one position (90.3%), intrahepatic stricture (88.7%), and on the left hepatic duct (32.3%). Strictures were usually surrounded by stones. The stritrures were mostly ring-shaped (97.1%), 3mm - <4mm in diameter (52.2%), 2-5mm long (53.6%) and all of them were benign. The average length and diameter of the strictures werw: 3.9 ± 2.9 mm and 3.6 ± 0.7 mm, respectively. Classification: mild stricture accounted for the highest rate (85.5%), moderate stricture was the next one (8.7%). The number, diameter and length of stricture were factors related to the rate of biliary stone  and stricture clearance after surgery with p < 0.05. Conclusion: Flexible cholangioscopy was an effective method to investigate the characteristics of biliary stricture. In patients with primary bile duct stones, the majority of stricture were mild, ring-shaped and all benign. They mostly were in one position with moderate diameter and short length. The number, diameter and length of stricture were related to the rate of biliary stone  and stricture clearance after surgery
