Abstract
Experience with 28 patients with toxic dilatation of the colon is reviewed. The operative mortality in this series was 32% (9/28). Eight of the 9 patients who died were found to have colonic perforations at operation; in contrast, the group of patients with no perforations had a mortality rate of only 6%. Colonic perforation and sepsis were the most significant factors contributing to mortality and morbidity in this series. A review of the literature showed an overall operative mortality rate of 19.5% for patients with toxic megacolon; the mortality rate was 41% for patients with perforations and 8.8% for patients without perforations. It appears that the keystone to successful management is the avoidance of colonic perforation and sepsis; protracted medical management of toxic megacolon seems to have been at least partly responsible for these complications. Sixteen of the 18 survivors following subtotal colectomy required removal of the rectum within 9 months because of continued symptoms and disease in the rectal stump.
