Fulminant amoebic colitis: a rare fierce presentation of a common pathology

Abstract

We conducted a retrospective study of patients with fulminant amoebic colitis (FAC) over a 20 year period in an urban tertiary care hospital in Pakistan. After consideration for inclusion and exclusion criteria 25 cases were identified as FAC with the most common presentations being abdominal pain (84%). Nineteen (76%) underwent laparotomy for peritonitis with evidence of: colonic perforation in 10 (40%); faecal peritonitis in eight (32%); bowel gangrene in one (4%); and intra-abdominal abscess in two (8%). Nine (36%) deaths were recorded in the series – eight (53%) in the operated group and one (16.6%) in the medically-treated group. The optimal outcome can be achieved in FAC with aggressive resuscitation, intravenous broad-spectrum antibiotics, including metronidazole, and total colectomy without anastomosis in patients with peritonitis.
