[Application of biological mesh for reconstruction of pelvic floor in patients with perineal hernia].
摘要
OBJECTIVE: To investigate the effectiveness of repair procedure using biological mesh with Onlay-Reinforce technique in patients with perineal hernia. METHODS: Between January 2005 and December 2012, 9 patients with perineal hernia after laparoscopic abdominoperineal resection for rectal cancer (Miles operation) were treated. There were 3 males and 6 females with a mean age of 70 years (range, 61-78 years). The disease duration was 1-9 months (mean, 4.5 months). The most beginning symptom was distending pain in perineal region, and then reducible mass was found without bowel incarceration. All patients underwent hernia repair using biological mesh with Onlay-Reinforce technique through original perineal incision. RESULTS: The hernial size was 9.8-20.5 cm2 (mean, 16.0 cm2); the size of biological mesh was 58-80 cm2 (mean, 70.2 cm2); and the intraoperative blood loss was 10-80 mL (mean, 50.5 mL). All of the patients underwent repair operation successfully. The operation time was 45-90 minutes (mean, 60.6 minutes); and the hospitalization time was 4-7 days (mean, 5.9 days). One patient had urine retention, which was relieved after 7 days indwelling catheter. All the wounds healed by first intention without infection. The patients were followed up 14.5-60.7 months (mean, 37.8 months). No chronic pain, obvious foreign body sensation, or hernia recurrence developed. CONCLUSION: Use of biological mesh with Onlay-Reinforce technique for the repair ofperineal hernia after Miles operation is safe and effective.
