Perineal hernias after proctectomy. A new approach to repair

Perineal herniation of pelvic organs rarely occurs after abdominoperineal resection of the rectum, but it does present a difficult surgical dilemma. The case of a patient with perineal herniation of the small bowel and urinary bladder into a proctectomy wound has been described. This was repaired using a transabdominal pelvic sling with Marlex followed by gracilis muscle transplantation. Review of the literature yielded 18 previous case reports of perineal hernia after proctectomy, and the results of various surgical approaches have been detailed and discussed. The technique of gracilis muscle transplantation offers a definite advantage when the hernia occurs in a contaminated perineal wound.
