A 80-year-old woman with duplication of the common bile duct with retrograde endoscopic cholangiopancreatography (ERCP) who did not resolve the symptoms. Our case is a variant of type IV to the classification of DCBC. The MR cholangiography and presurgical ERCP allows assessment of the bile ducts, their caliber, and assessment of abnormalities. The treatment before DCBC will depend on the clinic and the type of opening of the CBCA. It is important to perform a pre-surgical study and during surgery with CIO.
