Abstract

Malignant duodenocolic fistula is a rare complication of colon cancer, and this usually develops as the right-side colon cancer that invades the duodenal bulb. The fistula often results in watery diarrhea, weight loss and feculent vomiting. A barium enema or duodenography have been the most useful diagnostic procedures, and the fistula is directly confirmed by an endoscopic examination. Curative resection is not possible in many cases due to metastasis or local invasion, so a palliative operation can be performed to relieve symptoms, but it cannot completely prevent the vomiting or diarrhea. Seven Korean cases of malignant duodenocolic fistula have been previously reported on, and an operation was performed in six cases. We report here on a case of duodenocolic fistula with intestinal obstruction that arouse from a right-side colon cancer, and this was successfully managed by placing covered metallic stents at the duodenum and hepatic flexure.
