[Synchronous Triple Malignant Tumors (Hilar Cholangiocarcinoma, Ascending Colon Cancer, Liposarcoma) Resected in a Two-Stage Procedure--A Case Report].
2015
Abstract A 70-year-old man with a history of myocardial infarction (MI) and taking 2 antiplatelet drugs was diagnosed with anemia his 6-month post-MI checkup. A lower gastrointestinal endoscopy detected ascending colon cancer, and contrast-enhanced a computed tomography scan revealed hilar cholangiocarcinoma as well as lesions suspicious for gastrointestinal stromal tumors of the small intestine. The patient was given a preoperative diagnosis of synchronous triple malignant tumors. The decision to perform a two-stage procedure was made for the following reasons: the impossibility of discontinuing antiplatelet drugs 6 months after drug-eluting stent placement, continuous bleeding due to colon cancer and the possibility of suffering severe stress from surgery while at high risk for diseases such as hepatic failure. In the initial procedure, a right hemicolectomy and surgical resection of the mesenteric tumor (later diagnosed as a liposarcoma) were performed after portal vein embolization. Confirmation of an enlarged residual liver was confirmed 2 months after the initial procedure. The patient underwent right hepatectomy and resection of the extrahepatic bile duct and the biliary tract was surgically reconstructed. Safe resection of tumors was successfully performed by choosing a two-stage procedure for triple malignancy, including hilar cholangiocarcinoma, ascending colon cancer, and liposarcoma, in a single patient.
