ULCERATIVE COLITIS COMPLICATED BY INTERNAL FISTULA : REPORT OF A CASE

Abstract

We reported a case of ulcerative colitis with a rare and unique complication. The case was a 50 year-old man with a history of ulcerative colitis for three years, who complicated internal fistula between the transverse and descending colon at the colonic splenic flexure. There was neither clinical nor pathological evidence of Crohn's disease. The presence of a internal fistula in the colon, which is characteristic in Crohn's disease, is distinctly unusual in ulcerative colitis, and has never been reported in the literature.
