Correlation between anatomical structure and recurrence of common bile dust stones after endoscopic choledochlithotomy

Abstract

Objective To investigate the correlation between anatomical structure and recurrence of common bile duct stones. Methods The clinical data of 195 patients with common bile duct stones were studied, including 37 patients with recurrent bile duct stones. The correlation between anatomical structure and the recurrence of common bile duct stones were analyzed by univariate and multivariate analysis. Results Univariate analysis revealed that history of cholecystectomy, choledocholithotomy, periampullar diverticulum, papilla hypertrophy or stenosis, intramural duodenal bile duct abnormalities, common bile duct stricture, choledochectasia and angulated common bile dust were risk factors of recurrence. Multivariate logistic regression analysis showed that past history of cholecystectomy, periampullary diverticulum, angulated common bile dust, choledochectasia were independent risk factors for the recurrence of common bile duct stones. Conclusion Patients with anatomical structure of past cholecystectom, periampullary diverticulum, choledochectasia, angulated common bile dust are prone to recurrence of common bile duct stones.
