Abstract

Background: In contrast to open-surgery abdominoperineal excision (APE) for rectal cancer, postoperative perineal hernia (PPH) is reported to increase after extralevator APE and endoscopic surgery. In this study, therefore, we aimed to determine the risk factors for PPH after endoscopic APE. Methods: A total 73 patients who underwent endoscopic APE for rectal cancer were collected from January 2009 to March 2020, and the risk factors for PPH were analyzed retrospectively. Results: Nineteen patients (26%) developed PPH after endoscopic APE, and the diagnosis of PPH was made at 9–393 days (median: 183 days) after initial surgery. Logistic regression analysis showed that absence of pelvic peritoneal closure alone increased the incidence of PPH significantly (odds ratio; 13.76, 95% confidence interval; 1.48–1884.84, p = 0.004). Conclusions: This preliminary study showed that pelvic peritoneal closure could prevent PPH after endoscopic APE.
