Comparison of Sublay and Onlay Mesh Repair in Ventral Hernia

This study is designed to compare two different surgical methods for repairing ventral abdominal wall hernias: sublay mesh repair and onlay mesh repair. Ventral hernias are common and occur when tissue pushes through a weak spot in the abdominal wall. Both sublay and onlay techniques involve placing a synthetic mesh to strengthen the abdominal wall, but the position of the mesh differs. This trial will evaluate postoperative outcomes, including surgical wound infections, seroma (fluid buildup), and hernia recurrence, over a six-month follow-up period. The findings are expected to help inform surgical decision-making, particularly in resource-limited hospitals.
