Purpose: Laparoscopic ventral hernia repair with mesh versus laparoscopic ventral hernia defect closure with mesh reinforcement. The primary end-point was recurrence.
Methods: Retrospective review of patients who underwent laparoscopic ventral hernia repair for small- and medium-sized hernias between July 2000 and September 2011. These patients were divided: (1) repair with mesh alone (non-closure group) and (2) those with hernia defect closure and mesh reinforcement (closure group). The closure group was further divided by technique: percutaneous versus intracorporeal closure of the defect.
Results: 128 patients were studied: 93 patients (72.66 %) in the non-closure group and 35 patients (27.34 %) in the closure group. Follow-up was available in 105 patients (82.03 %) at a mean of 797.2 days (range 7-3,286 days). In the non-closure group there were 14 patients (15.05 %) with postoperative complications and 8 patients (22.86 %) in the closure group, four of which were seromas. Fourteen patients (19.18 %) developed recurrent hernias in the non-closure group with an average time to presentation of 23.17 months (range 5.3-75.3). Two patients (6.25 %) developed recurrent hernias in the percutaneous group with an average time to presentation of 12.95 months (range 9.57-16.33). There have been no recurrences in patients whose defect was closed intracorporeally.
Conclusion: Although our study demonstrated a difference in recurrence rates of 19.18 % in the non-closure group versus 6.25 % in the closure group, the difference did not reach statistical significance. A larger series with longer follow-up may demonstrate clinical significance.
