Perforation of the large bowel during colonoscopy in Singapore.

The management of seven patients with colonoscopy-related perforations is described. This study demonstrates the need for an early laparotomy. A high index of suspicion is required to reach an early diagnosis. Patients with no preexisting medical problems who underwent early surgery recovered with little morbidity. In elderly patients (greater than 75 years), colonoscopic perforation can be fatal. Endoscopy should be performed with special care in such patients.
