Laparoscopic Mesh Repair for Perineal Hernia after En Bloc Resection of an Aggressive Angiomyxoma Using a Modified Sacral Colpopexy Technique.

ABSTRACT

STUDY OBJECTIVE: To demonstrate laparoscopic mesh repair of perineal hernia (PH) by a modified sacral colpopexy technique. DESIGN: Step-by-step demonstration of the technique used for the surgical repair of PH after gynecologic surgery. SETTING: PH is defined as a pelvic floor defect through which the intra-abdominal viscera may protrude [1]. The reported incidence of PH ranges from 0.6% to 3%, and it generally occurs after rectal or prostate surgery [2]. Owing to its low incidence, there is no standard procedure to treat PH [3]. Herein, we demonstrate a successful case of PH treatment with a composite mesh (Dual Mesh; W. L. Gore & Associates, Newark, DE) after gynecologic surgery by a modified laparoscopic sacral colpopexy technique, which was approved by our institutional review board. INTERVENTIONS: The patient had undergone extralevator abdominoperineal excision for an aggressive angiomyxoma and developed a sigmoid colon-protrudent PH after the surgery [4]. The patient suffered from defecatory dysfunction and dysmenorrhea. A total laparoscopic hysterectomy, bilateral salpingo-oophorectomy, and mesh repair of the PH were performed at 2 years after the primary surgery, and they were successful without any intra- or postoperative complications. Because the pelvic floor defect was too large to secure the mesh by a simple placement, we applied the modified sacral colpopexy technique using 2-0 proline (ETHICON, Tokyo, Japan) to cover and support this defect. At 12 months after the second surgery, there was no sign of recurrence of PH and aggressive angiomyxoma, and the preoperative symptoms had diminished. CONCLUSION: Laparoscopic mesh repair by the modified sacral colpopexy technique is safe and effective to manage PH.
