Prospective, multicenter study of laparoscopic ventral hernioplasty: Preliminary results

Background: A standard technique for laparoscopic ventral hernioplasty (peritoneal onlay using an expanded polytetrafluoroethylene [ePTFE] patch for hernias ≥4 cm²) is being used in a prospective, multicenter, long-term study. Methods: Demographic, operative, and postoperative data were collected and analyzed. Follow-up clinical evaluations were conducted 7-10 days, 4 weeks, 6 months, 1 year, and then annually after surgery in all patients. Results: In the first 2 years of the study, 144 patients were enrolled; nine were lost to follow-up. The mean operating time was 120 min. The mean follow-up was 222 days (range 5-731). Postoperative complications were five infections, three cases of prolonged ileus, one bowel obstruction, 23 seromas (15 resolved without intervention), and six hernia recurrences. Hospital discharge occurred a mean of 2.3 days after surgery and return to normal activity a mean of 15 days postoperatively. Conclusions: Laparoscopic prosthetic ventral hernioplasty avoids the large wound required in open repairs, with attendant complications and recurrences, and appears safe, especially if an ePTFE mesh is used. Compared with conventional open ventral hernioplasty, the laparoscopic technique may also allow shorter hospilalization and a quicker return to normal activities after surgery.
