Rectal perforation during barium enema. Report of a case.

Perforation of the colon or rectum during the course of barium-enema examination is estimated to occur in approximately 500 patients annually in the United States. It has been over 30 years since the last collective review on this subject reported a prohibitively high mortality and morbidity. Since that time, much has been learned about the treatment of patients with peritonitis and bowel perforation, many new and more effective antibiotics have become available, and the management of shock has become infinitely more sophisticated. A review of recently reported cases suggests that the mortality rate and possibly the early morbidity have fallen markedly. Late complications such as adhesive small-bowel obstruction and retroperitoneal fibrosis with ureteral stenosis are well described, but data on the incidence of these long-term sequelae are still not available.
