Complication Rate of Onlay vs Sublay Mesh Repair in Incisional Hernia

This randomized controlled trial was conducted at the Department of Surgery, Hayatabad Medical Complex, Peshawar. Eligible patients with incisional hernia were randomized into two parallel groups: sublay mesh repair and onlay mesh repair. Procedures were performed by a single experienced general surgeon. Postoperative complications were assessed by an independent surgeon blinded to the type of procedure. Patients were followed for a period of three months to evaluate safety and recurrence outcomes.
