[Case of Intraductal Papillary Neoplasm of Bile Duct with Invasive Carcinoma after Choledochoduodenostomy for Intrahepatic Duct Stones].

Abstract

Endoscopic retrograde cholangiopancreatography or percutaneous techniques are performed for bile drainage and removing bile duct stones. Nevertheless, surgical stone removal can be performed in cases where cholelithiasis with concomitant choledocholithiasis is checked. While forming an anastomosis for bile drainage, the anatomical structure may change from its normal state. Choledochoduodenostomy is one classical and commonly used method for bile drainage anastomosis. The data on long-term complications, including malignancy, associated with this method are limited. Some reports suggest that choledochoduodenostomy may be linked to the development of bile duct cancer. This paper presents a case of intraductal papillary neoplasm of a bile duct (a rare neoplasm of a bile duct) with invasive carcinoma that developed a long time after performing lateral sectionectomy, cholecystectomy, and choledochoduodenostomy due to intrahepatic stones and gallbladder stones.
