title: [Toxic megacolon secondary to ischemic colitis. Report of a case].
abstract: We report a 67 years old male that consulted due to bloody diarrhea of several months of evolution and emaciation. According to endoscopic and radiological findings, the diagnosis of severe ulcerative colitis was made. Fifteen days after admission, the patient was subjected to an emergency total colectomy due to a toxic megacolon. The pathological study showed an ischemic colitis with extensive longitudinal ulcers in the antimesenteric border, presence of granulation tissue with inflammation and transmural fibrosis. Intestinal transit was reconstituted six months later and after 12 months of follow up the patient is in good conditions.
