Brief Summary

Abdominoperineal resection leaves an empty space to be filled by mesh or musculocutaneus flap. Several studies have reported over 30% morbidity with perineal wound healing after abdominoperineal resection. Preoperative radiotherapy is a strong predictor for perineal complications. Musculocutaneus flaps and use of biological mesh seem to minimize perineal morbidity. The role of omentoplasty at APR is controversial. Previous studies on synthetic mesh repair on perineum are almost lacking.

Study Arms (1)

Mesh group

After resection, pelvic floor is reconstructed by synthetic composite mesh (Symbotex, Medtronic) and covered with subcutaneous flap.

Device: Composite mesh

Interventions

Pelvic floor is reconstructed by synthetic composite mesh (Symbotex, Medtronic) to improve healing and prevent perineal herniation.
