Barium enema studies revealed that postoperative mucosal prolapse in patients with ano-rectal abnormalities is entirely due to abnormaly elongated distance of the anal canal between the attachment of the puborectal sling and that of the external anal sphincter. Anoplasty for these patients was done to remove the elongated portion of the anal canal and to approximate the distance between the puborectal sling and the external anal sphincter muscle, without use of sliding skin graft methods. Our anoplasty was used 23 times in 19 patients, and gave satisfactory results.
