Comparison of Onlay Mesh Repair and Sublay Mesh Repair in Umbilical Hernia Surgery

Umbilical hernia is a common condition that is frequently treated with surgical mesh repair to reduce recurrence rates. Among the commonly used techniques, onlay mesh repair and sublay mesh repair are widely performed; however, there is ongoing debate regarding their comparative effectiveness and safety. The aim of this study is to compare onlay mesh repair and sublay mesh repair in patients undergoing elective umbilical hernia surgery, with respect to postoperative complications, recurrence rates, operative outcomes, and length of hospital stay. By evaluating clinical outcomes associated with each technique, this study seeks to contribute evidence to guide the selection of the most appropriate surgical approach for umbilical hernia repair.
