Colonoscopic decompression for pseudo-obstruction of the colon.

The purpose of this report was to review the authors' experience with colonoscopy as a method of treating patients with acute colonic distention. For the period 1981-1987, 19 patients at two teaching hospitals met the selection criteria for this study. In terms of measurable decompression of a colon distention, colonoscopy was successful in 89 per cent of patients, although 41 per cent required repeat endoscopic decompression during their hospital stay. The procedure failed in two patients (11%) and operative decompression was necessary. The authors have found that colonoscopy is a useful procedure for determining the cause of progressive colon distention and for providing safe and effective treatment.
