Posterior plication of the rectum for rectal prolapse in children.

Fourteen patients with rectal prolapse (age range, 1 to 12 years) underwent posterior plication of the rectum for rectal prolapse. The procedure consisted of (1) natal cleft incision, (2) midline separation of the levator muscle, (3) dissection of two thirds of the circumference of the rectum, (4) plication of the posterior wall of the rectum using U-shaped mattress sutures, and (5) fixation of the sutures of the rectal wall to the coccyx. There has been no recurrence of prolapse in any of the patients. The authors' experience suggests that an elongated rectum is responsible for prolapse. This simple but definitive technique is recommended.
