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 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)
retrospective (up to 8 years)
The association between common bile duct angle and existence of recurrent CBD stone
retrospective (up to 8 years)
The risk factors for the development of recurrent CBD stone
retrospective (up to 8 years)
Periampullary diverticulum has been postulated as risk factor of recurrent CBD stone.
Narrow CBD angle has been postulated as risk factor for the development of recurrent CBD stone
Patients who were diagnosed as CBD stone or calculous cholangitis will be enrolled. These patients will be divided by patienst with recurrent CBD stone (devlopment of CBD stone after 1 year from the first development of CBD stone) or not .
