    Abstract:
    Colon complications are a potential source of serious morbidity to the immunosuppressed patient. Because of multiple predisposing factors, renal transplant patients are a high-risk group for the development of acute colonic pseudo-obstruction. During a recent 18-month period, 290 renal transplants (79 living, 211 cadaveric donors) were performed and prospectively analyzed for colonic dysmotility. A total of 34 episodes of acute colonic ileus (30 primary, 4 recurrent) occurred in 30 (10.3%) renal transplant recipients. Acute colonic ileus was more frequent after living-donor transplantation (19.0% vs. 7.1%, p = 0.006). Analysis of multiple variables revealed that the incidence of acute colonic ileus was directly related to mean cumulative prednisone dosage (p less than 0.05). Medical therapy (rapid steroid reduction, bowel rest) resulted in a 76.7% response, whereas 8 patients underwent colonoscopy because of progression to acute pseudo-obstruction. The success rate for colonoscopic decompression was 87.5%; in 1 patient cecal perforation developed after unsuccessful decompression. Overall, 33 of 34 (97.1%) episodes of acute colonic ileus were successfully treated. Steroid-induced ileus (pseudo-obstruction) is a potentially malignant early form of colonic dysmotility infrequently reported in transplant recipients. Successful management requires early clinical recognition, reduction in steroid dosage, bowel rest, and urgent colonoscopic decompression in select cases.
