Intraductal papillary-mucinous carcinoma penetrating into the common bile duct and duodenum. : a case report

Abstract

A 77-year-old male was admitted to our hospital with a chief complaint of jaundice. Abdominal computed tomography scans showed a cystic lesion containing some enhanced parts in the pancreas head and dilated main pancreatic duct. Endoscopy showed an enlarged orifice of the papilla of Vater with mucous secretion and fistula formation between the duodenum and the cystic lesion. Endoscopic retrograde cholangiopancreatography showed a filling defect in the common bile duct and contrast medium flowing into the cystic lesion from the common bile duct via a fistula. He was diagnosed with intraductal papillary-mucinous carcinoma (IPMC) penetrating into the common bile duct and duodenum. It was difficult to control the obstructive jaundice, but after a fully covered self-expandable metallic stent was placed in the lower common bile duct there was a good clinical outcome.
