摘要
Duodenum mucinous carcinoma is very rare, and the prognosis of the patient is very bad, especially when the tumor is invasive to other organs. In this case, duodenum carcinoma was invasive to common bile duct and transverse colon. Mucinous fluid, which was secreted from a duodenum tumor, was found in the dilatated bile duct. The intraductal papillary neoplasm of the bile duct was considered a differential diagnosis. We performed aggressive resection and had a good prognosis. A 74-year-old woman received a diagnosis of cholangitis and was treated with antibiotic drugs. Endoscopic retrograde cholangiopancreatography revealed a defect in the lower common bile duct with the mucoid fluid. We suspected intraductal papillary neoplasm of the bile duct, but no malignant cells were detected. One year later, gastrointestinal fiberscopy revealed a villous tumor in the postbulbar portion of the duodenum; adenocarcinoma was detected in biopsy specimens. Computed tomography revealed dilatation of the duodenum with an enhanced tumor, and dilatation of both the common and intrahepatic bile ducts. Magnetic resonance cholangiopancreatography revealed that the duodenum was connected with the common bile duct and ascending colon. We resected the segmental duodenum, extrahepatic bile duct, left lobe of liver, a partial of the transverse colon, and associated lymph nodes. Although the advanced duodenal carcinoma had poor prognosis, the patient was alive, without recurrence, 5 years after the operation.
