Rectal prolapse that is intractable to the usual medical therapy was successfully managed without significant complications in 10 patients by simple subcutaneous encirclement of the anus with a heavy nonabsorbable suture, which was in place until the suture was removed or broke after 4 to 6 months. Four patients required two sutures and one needed a third insertion. Since this procedure is simple, has no serious complications, and controls rectal prolapse, it is recommended as the preferred initial surgical treatment of this condition.
