Purpose: The incidence of complications after colonoscopy is very low. The complications after colonoscopy that are of clinical concern are bleeding and perforation. The present study was conducted to determine the clinical outcomes and the risk factors of a colostomy or a colectomy after colonoscopic colon perforation.

Methods: From March 2009 to December 2012, the records of all patients who were treated for colorectal perforation after colonoscopy were reviewed retrospectively. The following parameters were evaluated: age, sex, purpose of colonoscopy, management of the colonic perforation, and interval from colonoscopy to the diagnosis of a colonic perforation. A retrospective analysis was performed to determine the risk factors associated with major surgery for the treatment of a colon perforation after colonoscopy.

Results: A total 27 patients were included in the present study. The mean age was 62 years, and 16 were males. The purpose of colonoscopy was diagnostic in 18 patients. The most common perforation site was the sigmoid colon. Colonic perforation was diagnosed during colonoscopy in 14 patients, just after colonoscopy in 5 patients, and 24 hours or more after colonoscopy in 8 patients. For the treatment of colonic perforation, endoscopic clipping was performed in 3 patients, primary closure in 15 patients, colon resection in 2 patients, Hartmann’s procedures in 4 patients, and diverting colostomy in 3 patients. If the diagnosis of perforation after colonoscopy was delayed for more than 24 hours, the need for major treatment was increased significantly.

Conclusion: Although a colonic perforation after colonoscopy is rare, if the morbidity and the mortality associated with the colonic perforation are to be reduced, prompt diagnosis and management are very important.
