PURPOSE: This study was designed to describe and evaluate the efficacy of sutured perineal omentoplasty on perineal wound healing after abdominoperineal resection for adenocarcinoma of the lower rectum. METHODS: Charts of patients who underwent abdominoperineal resection for adenocarcinoma of the rectum from June 1995 to December 2001 were reviewed for mortality, morbidity, and perineal healing. Abdominoperineal resection was accomplished according to Miles combined with total mesorectal excision. The omentum was pediculized on the left gastroepiploic artery and tightly sewn to the subcutaneous fatty tissue. The perineal skin was then closed primarily. RESULTS: A total of 104 patients were included in the study. The mean age at surgery was 65 (range, 13–91) years. The distance of the tumor from the anal sphincters was 0.45 ± 0.9 mm (range, 0–50). During the study period, 92 patients (88 percent) had sutured perineal omentoplasty. The rate of primary perineal wound healing was 80 percent. Postoperative perineal wound complications consisted of perineal abscess in seven patients. Six of these patients had a sutured perineal omentoplasty (6 percent). Only four patients required a surgical drainage. Minor perineal suppuration occurred in four patients (4 percent), whereas partial perineal wound dehiscence occurred in eight patients (8 percent). All wounds healed completely at three months. Intestinal obstruction occurred in three patients (3 percent). No complication of the pedicled omentoplasty was observed. CONCLUSIONS: This study demonstrated that sutured perineal omentoplasty is possible in the majority of patients after abdominoperineal resection for adenocarcinoma of the lower rectum with excellent primary perineal wound healing.
