In this retrospective study, the investigators evaluate the relationship of post-ERCP-choledocholithiasis(PEC ) and the gallbladder status as a risk factor.
When patients have common bile duct(CBD) stones, ERCP is widely used for stone extraction instead of clinical operation. ERCP has many advantages like less injury or faster recovery. However, according to literature, ERCP will has a mostly 10% possibility to get an acute purulent cholecystitis, which often requires emergency intervention, therefore, it is necessary to know if the gallbladder status(chronic disease) is one of the important risk factors of PEC like the gallbladder wall thickness, chronic cholecystitis, polyps,crudely or calculus.
