A 78-year-old woman underwent cystectomy of left ovary 1 year ago. She came to our hospital with the chief complaint of bulging of the abdominal scar before 2 months. The bulging of 3×3 cm was recognized in the operation scar in a standing position. CT scan of the abdomen revealed incisional hernia in upper part of operation wound. The hernia orifice was 2.5×2.5 cm. A radical operation was therefore performed. Under local anesthesia, Ventralex was fixed by insertion, and the hernia was repaired. The adhesion between the omentum and the caudal part of operation scar was dissected. In the condition patch was inserted and made to adhere to abdominal wall, strap was fixed in the rectus sheath. The postoperative course was good. Repair of incisional hernia using Ventralex seemed to be useful operative method, which could enforce the tension free operation in the minimum invasion
