perineal rectosigmoidectomy
ProcedureIn an Altemeier perineal rectosigmoidectomy, a full-thickness circumferential incision is made in the prolapsed rectum about 1-2 cm from the dentate line (see the image below). The hernia sac is entered, and the prolapse is delivered. The mesentery of the prolapsed bowel is serially ligated until no further redundant bowel can be pulled down. The bowel is transected and either hand-sewn to the distal anal canal or stapled with a circular stapler. Before anastomosis, some surgeons plicate the levator ani muscles anteriorly, which may help improve continence.
