Rectal prolapse: 17-year experience with the posterior repair and suspension.

Using a posterior repair and rectal suspension procedure for those patients who need surgical treatment of rectal prolapse, we have treated 46 patients over a period of 17 years at Children's Mercy Hospital in Kansas City, MO. One patient with caudal dysgenesis died of multiple congenital anomalies following two unsuccessful attempts at posterior repair and suspension. Four patients developed a recurrence afterwards, which was found to be due to sigmoid intussusception and, presumably, had played a major part in their original prolapse. Two of these required resection, one from the transanal approach and one from the transabdominal approach. One resolved spontaneously and another is as yet unresolved. Three patients had minor mucosal prolapse that was transient and two patients had extrusion of silk sutures but continued to have a very satisfactory result. Overall, 42 patients had satisfactory resolution of their rectal prolapse. Three of the four patients who had unsatisfactory results had associated anomalies that contributed to their poor outcome.
