Core Tip
Core Tip: Double common bile duct (DCBD) is an extremely rare congenital biliary tract anomaly. We present herein, a rare case of DCBD manifesting as a recurrent pyogenic cholangitis. It is substantial to establish complete stone clearance during endoscopic retrograde cholangiopancreatography because residual stone is a probable risk factor for recurrent cholangitis. However, DCBD, an extremely rare anomaly, can completely mask the presence of remnant bile duct stones for biliary endoscopists. In this case, recurrent cholangitis, which occurred immediately after bile duct stone clearance was a clue to recognize DCBD. Although this is a rare condition, our case highlights the importance of recognizing DCBD because stones in the unrecognized bile duct could make the patient’s prognosis critical.
