Kết quả nội soi tán sỏi đường mật trong gan qua đường hầm Kehr bằng ống soi mềm với năng lượng điện thủy lực tại Bệnh viện Trung ương Quân đội 108

Abstract

Objective: To evaluate the results of treatment of residual bile duct stones in the liver using a soft endoscope through the Kehr tunnel for electrohydraulic lithotripsy. Subject and method: 76 patients were diagnosed with residual intrahepatic bile duct stones by ultrasound or magnetic resonance, and still had Kehr drainage. Endoscopically using a flexible endoscope for electrohydraulic lithotripsy through the Kehr tunnel at 108 Military Central Hospital from January 1, 2022 to January 1, 2024. Method: A cross-sectional, retrospective, prospective, non-controlled study. Result: 100% of patients had stones left in the liver and had a history of bile duct stone surgery. Female/male ratio=1.81. The rate of stones in the liver on both sides was the highest: 44.74%. Access to stones reached 97.5%. The stone-free rate was 88.16%, while the stone-free rate was 11.84%. Biliary stenosis accounted for 19.74%, mainly intrahepatic biliary stenosis. The average number of flirting times was 1.05 ± 0.22, at least 1 time, at most 2 times. The time for 1 lithotripsy through the Kehr tunnel was 61.02 ± 32.46 minutes, the shortest was 15 minutes, the longest was 160 minutes. Complications (1.32%) (Kehr tunnel rupture) were treated medically after 3 days of stable discharge from the hospital. Days of treatment after surgery: Average 1.77 ± 0.82 days, shortest was 01 day, longest was 04 days. Conclusion: Endoscopic soft tube through Kehr electrohydraulic lithotripsy is a safe and highly effective method in treating residual bile duct stones in the liver
