Objective: To evaluate the treatment outcomes of common bile duct stones by stone extraction using endoscopic retrograde cholangiopancreatography at Trung Vuong Hospital.
Subjects and methods: This uncontrolled clinical interventional study included 109 patients with common bile duct stones who were indicated for endoscopic retrograde cholangiopancreatography at Trung Vuong Hospital.
Results: The rate of complete stone clearance was 89.9%, effective biliary drainage was achieved in 97.2%, and favorable overall treatment outcomes were recorded in 92.7% of patients. The rate of intra-procedural or post-procedural complications was 4.6%. After 72 hours, the proportion of patients with fever decreased from 52.3% to 2.8%, and the visual analogue scale pain score decreased from 56.7 ± 19.5 to 20.2 ± 12.9. Total bilirubin decreased from 52.2 µmol/L to 31.0 µmol/L, and white blood cell count decreased from 9.79 G/L to 8.47 G/L. All changes were statistically significant, with p < 0.001. Patients with unfavorable outcomes had a higher pre-procedural white blood cell count than those with favorable outcomes.
Conclusion: In this study, stone extraction for common bile duct stones using endoscopic retrograde cholangiopancreatography achieved a high success rate, early improvement in clinical symptoms and laboratory parameters after intervention, and a low complication rate during in-hospital follow-up.
