The optimal management of the perineal defect following abdominoperineal excision for anorectal malignancy remains a source of debate. The repopularization of extralevator resection means colorectal surgeons are confronted with larger perineal wounds. There are several surgical options available—primary perineal closure and drainage, omentoplasty, biological or synthetic mesh placement, musculocutaneous flap repair, and negative wound pressure therapy. These options are discussed along with the potential benefits and complications of each. There remains no consensus on which management strategy is superior; thus, each case must be tailored for each individual patient. Surgical expertise and availability of a multidisciplinary team approach are important considerations.
