Abstract
This study aimed to determine the outcome for patients who had undergone perineal hernia repair, via a perineal approach, using a biological mesh post-abdominoperineal excision (APE) for anorectal cancer. All consecutive patients having undergone perineal hernia repair involving an extracellular matrix of porcine small intestinal submucosa at our hospital between 2015 and 2018 were included. Follow-up clinical examinations and computed tomography scans were performed. Six patients were treated surgically for symptomatic perineal hernia after a median of 31 months from APE. The median follow-up after hernia repair was 11 months (interquartile range [IQR], 6-35 months). Three patients (50%) developed a recurrent perineal hernia after a median interval of 6 months. Perineal hernia repair using a biological mesh resulted in a high recurrence rate in patients who had undergone APE for anorectal cancer.
