Amoebic perforation of the bowel: Experiences with 26 cases

Abstract

Abstract Over a period of 14½ years, 26 instances of amoebic perfoation of the bowel occurring in 25 patients were treated surgically. Nineteen perforations occurred in males and 7 in females, whose ages ranged from 3 to 74 years. The duration of symptoms varied from 12 h up to 5 months (average 15 days). All patients were toxic and a right lower quadrant mass was present in 14. The correct diagnosis was made or suspected in 14 (54 per cent). Amoebic perforation of the bowel should be suspected in patients presenting with an acute abdomen if a past history of fever, pain and diarrhoea is obtained, particularly if a large tender mass is present in the right iliac fossa. Resctional surgery was performed in 7 patients, with a mortality of 71 per cent, whereas procedures designed to divert the faecal stream were carried out in 19, with a mortality of 43 per cent. All 6 patients with concomitant liver absesses died. If these patients are excluded, the mortality from resections was 60 per cent and from faecal diversion 27 per cent. Faecal diversion with wide drainage is the treatment of choice for amoebic perforation of the colon.
