[Transcatheter arterial embolization for the continuous bleeding from duodenal carcinoma--a case report].

We report a case of duodenal carcinoma with continuous bleeding that was successfully treated with transcatheter arterial embolization using gelatin sponge particles. The case was a woman in her 70's who had a curative surgical resection for sigmoid colon cancer with liver and lung metastases, hepatic arterial infusion chemotherapy and radiofrequency ablation for liver metastasis in the past. She was admitted to our hospital because of liver abscess and anemia. Upper gastrointestinal endoscopy revealed active bleeding from a duodenal tumor. The biopsy of the specimens was made and showed duodenal adenocarcinoma. The patient was considered to be inoperable because of the liver abscess and transcatheter arterial embolization of an anterior superior pancreaticoduodenal artery through an inferior pancreaticoduodenal artery was performed for the continuous bleeding from duodenal carcinoma not completely treated by endoscopic hemostasis or frequent transfusion. After the tumor embolization anemia was improved and partial response was obtained by systemic chemotherapy of mFOLFOX6. Transcatheter arterial embolization for a continuous bleeding from duodenal carcinoma is a feasible and effective method as a noninvasive therapy when it is unabled to be treated by surgical resection or endoscopic therapy.
