Abstract
A 90-year-old man underwent laparoscopic abdominoperineal resection (APR) for rectal cancer. The tumor was fstage II (T2N0M0) according to the UICC classification. He was discharged on the 18th postoperative day with no complications. About 6 months after the APR, he was aware of distension in the perineum. He complained of pain and an unpleasant feeling when he walked for a long time. Abdominal MRI showed that the small intestine protruded from the pelvic area to the perineum. A secondary perineal hernia was diagnosed. Repair of the perineal hernia was performed with Composix mesh. There has been no recurrence of the hernia. A secondary perineal hernia is rare. Excluding those presented in conference proceeding, 23 cases have been reported in Japan. The present case is described, and the clinical features are reviewed based on the relevant literature.
