Abstract
A 67-year-old man was admitted for abdominoperineal resection with lateral lymph node dissection for rectal cancer. The final diagnosis was rectal carcinoma, Rb, type2, moderately differentiated tubular adenocarcinoma, MP, N1 (1/28), M0, cStage IIIa (post-therapeutic). Twelve months after the operation, bulging of the perineum appeared and gradually enlarged with discomfort. Computed tomography showed the small intestine was eventrating the subcutis of the perineum over the pelvic floor. Repair of the perineal hernia with artificial mesh was performed under laparotomy. Almost all perineal hernias occur after abdominoperineal resection and total pelvic exenteration. A transabdominal approach has the advantage of a good view of the pelvic floor and stable technique for mesh repair.
