Malignant duodeno-colic fistula is a rare complication of advanced colon cancer. The right colon cancer adjacent to the hepatic flexure can occasionally invade into the pancreas or duodenum, but the formation of fistula between the duodenum and colon is very rare. The patients usually complain chronic diarrhea, vomiting and belching of foul smelling gas. This results in physiologic complications such as weight loss, malnutrition, and electrolyte imbalance. It is well known that the barium enema is the most useful diagnostic procedure. We experienced the case of duodeno-colic fistula that arose from the right colon cancer, and the fistula was directly confirmed by an endoscopic examination.
