Description

<p>A 58-year-old man presented to a hospital with general fatigue and lower leg edema. He was referred to our hospital because of anemia and a gallbladder tumor. As a result of close examination, he was diagnosed as having gallbladder bleeding associated with gallbladder cancer (Gf, papillary-expanding type, hep, 50×40mm, cT2b, cPV0, cA0, cN0, cM0, Stage II B). In addition, endoscopic retrograde cholangiopancreatography (ERCP) performed preoperatively revealed association of pancreaticobiliary maljunction without bile duct dilatation, and duplication of the common bile duct which is a rare morphological abnormality. Extended cholecystectomy and lymphadenectomy were performed. This patient has been alive as of 24 months after surgery without any signs of recurrence. Duplicated bile ducts are extremely rare congenital malformations of the biliary tract, defined as “congenital anomalies in which two patent bile ducts open separately into the gastrointestinal tract.”. Only a few dozen cases have been reported in the past. We report a rare case of gallbladder cancer with duplication of the bile duct and pancreaticobiliary maljunction without bile duct dilatation, which presented with gallbladder bleeding.</p>
