[Duodeno-colic fistula due to cancer of the right colon].

The author presents a case of duodeno-colic fistula revealing carcinoma of the right hepatic flexure showing the difficulty of surgery. A right hemi-colectomy enlarged to the duodenum and pancreas is the ideal operation from a curative point of view, but rarely possible owing to the age of the patient and the constitutional background. The risk of breakdown of duodenal sutures, which is sometimes technically difficult after colonic removal, is far from negligible. The results of by-pass operations, with or without exclusion of the fistula, are poor and uncertain.
