Recurrent common bile duct stone is one of the risk factors of recurrent cholangitis. However, the exact pathophysiology or mechanism of recurrent cholangitis has not been established. Periampullary diverticulum and narrow angle of common bile duct have been postulated as risk factors of recurrent common bile duct stone. The aim of this study was to evaluate the association between periampullary dierticulum, angle of common bile duct and recurrent common bile duct stone.

The aim of this study was to evaluate the association between periampullary dierticulum, angle of common bile duct and recurrent common bile duct stone. This study is patient-control setting study. Firstly, from July 2007 through February 2014, all the patients who were performed ERCP will be enrolled. The inclusion criteria is the patients with common bile duct stone. The exclusion criteria is patients with biliary stenosis, PSC, retained GB stone, or who were lost to follow-up. The main outcome is the association between periampullary diverticulum, common bile duct angle, and recurrent CBD stone. This will be evaluated by univariate and multivariate analyses.

RECRUITINGThe association between existence of periampullary diverticulum and recurrent CBD stone
The association between existence of periampullary diverticulum and recurrent CBD stone will be assessed by univariate analysis.(unit of analysis: odds ratio, statistical method: Fisher's exact test)
Time frame: retrospective (up to 8 years)
The association between common bile duct angle and existence of recurrent CBD stone
The association between common bile duct angle and recurrent CBD stone will be assessed by univariate analysis (unit of analysis: angle, statistical method: student's t test)
Time frame: retrospective (up to 8 years)
