A 69-year-old man visited our emergency department because of the intermittent passage of tarry stool. At endoscopy, an ulcerated, oozing mass was found in the third portion of the duodenum (●" Fig.1). Furthermore, abdominal computed tomography revealed multiple hepatic tumors and a duodenal tumor (●" Fig.2, arrow). Biopsy specimens from both sites revealed adenocarcinoma, and a diagnosis of duodenal cancer with multiple hepatic metastases was established. Despite the parenteral administration of proton pump inhibitor therapy, the passage of tarry stools persisted, and the patient was dependent on transfusions. Four attempts at endoscopic therapy, including argon plasma coagulation and epinephrine injection, all failed to control the bleeding. The patient was not considered for surgery because of unresectable malignancy. He was put on parenteral nutrition, but the bleeding continued for a month. Because of the persistent bleeding with a requirement for daily transfusion, it was decided to use a Niti-S Comvi stent (TaeWoong Medical, Gyeonggi-do, South Korea) for tamponade of the bleeding tumor (●" Fig.3). Three days following placement of the metal stent, the passage of tarry stool started to decrease, and the patient resumed an oral diet. He was discharged 37 days after admission without further bleeding. The use of an enteralmetal stent is indicated mainly for the palliative management of malignant intestinal tract obstruction in patients with advanced malignancy of the esophagus, duodenum, stomach, pancreas, or colon [1]. Fully covered metal stents have also been used to treat esophageal perforation [2] and variceal bleeding [3]. The present case demonstrates that a fully covered metal stent can be a salvage tool [4] for the management of bleeding duodenal cancer when conventional endoscopicmeasures fail.
