Colonoscopic decompression for acute pseudoobstruction of the colon (Ogilvie's syndrome). Report of 22 cases and review of the literature.

This report has described a series of 22 patients who underwent colonoscopic decompression for acute pseudoobstruction of the colon and summarizes those cases previously reported in the literature. Twenty of the 22 patients (91 percent) were successfully treated by decompression initially. Fifteen patients (68 percent) were cured with the initial procedure, and 4 patients (18 percent) experienced recurrence. Overall, in 17 patients (77 percent), the pseudoobstruction resolved completely with colonoscopic decompression. Three patients (14 percent) underwent operation because of cecal dilatation refractory to colonoscopic decompression, and in one patient (4.5 percent), the colonic dilatation resolved spontaneously after a failed colonoscopy. Complications resulted in the death of one patient (4.5 percent). Our data are similar to those in the literature and indicate that colonoscopic decompression is a safe and efficacious first line of treatment for acute pseudoobstruction of the colon.
