Abstract
Poor perineal healing is a major complication of total or partial pelvic exenteration especially when the pelvis and perineum have previously been irradiated. Perineal, vulval or vaginoperineal reconstruction was performed in five women using the inferiorly based rectus abdominis myocutaneous flap. Primary perineal wound healing occurred in all patients and no flap-related complications developed. Primary healing of abdominal wall wounds occurred in all patients without incisional hernia. Three of the patients had an anterior or total pelvic exenteration with continent urinary diversion by the Mitrofanoff technique. Two of the patients had complete vaginal reconstruction and one patient had after-loading catheters inserted for postoperative interstitial irradiation. The patients were in hospital for 42, 28, 21, 17 and 15 days respectively. The longest stays were associated with training for self-catheterization of the continent urinary diversion. Median follow-up was 9 months. One patient developed two perineal recurrences at 16 months which were resected, and she remains disease-free 6 months later.
