OBJECTIVE: The purpose of this study was to evaluate ERCP and CT findings
of ectopic drainage of the common bile duct into the duodenal bulb.
CONCLUSION: Although rare, the diagnosis of ectopic drainage of the common
bile duct into the duodenal bulb is important to prevent inadvertent damage
during biliary tract or gastric surgery and to clarify the cause of chronic
peptic ulcers.
