Randomized prospective comparison of long-term results of onlay and sublay mesh repair techniques for incisional hernia

Özet

Objective: Incisional hernia is a significant problem after laparotomy, and there is still no consensus on an idealtreatment method. The aim of this study was to compare the results of onlay and sublay mesh repair techniques.Material and Methods: In this randomized prospective trial, 100 patients were divided into two groups: onlay andsublay groups. Recurrences were evaluated by performing a physical examination.Results: The median follow-up was 37.1 (26.6 to 46.5) months. In the onlay group, the mean operation time wassignificantly shorter. However, in terms of postoperative pain and wound complications, the sublay group had significantlybetter results. The recurrence rates were found to be similar in both groups (6% in the onlay group and2% in the sublay group).Conclusion: In the treatment of incisional hernia, sublay mesh repair is superior to onlay mesh repair in terms ofpostoperative pain and wound complications. Both techniques have similar recurrence rates.
