Sublay or Onlay? A Comparative Evaluation of Mesh Placement Techniques in Ventral Hernia Repair
Abstract: Background: Ventral hernia repair is a common surgical procedure. Prosthetic mesh reinforcement has substantially reduced recurrence rates. However, the optimal anatomical plane for mesh placement- onlay versus sublay- remains controversial. This study aimed to compare surgical outcomes and complication rates between onlay and sublay mesh repair in ventral hernia at Dr. Vithalrao Vikhe Patil Foundation Medical College and Hospital. Methods: A prospective comparative study was conducted over 6 months with 20 adult patients diagnosed with uncomplicated ventral hernias. Participants were randomly allocated into two groups: Group A (Onlay mesh repair) and Group B (Sublay mesh repair), with 10 patients in each. Primary outcomes included operative time, postoperative pain (VAS score), hospital stay duration, wound complications, seroma/hematoma formation, and early recurrence within 6 months. Results: The mean operative time was significantly longer in sublay compared to onlay repairs. Sublay repair demonstrated lower rates of wound infection and seroma formation. Hospital stay was shorter in sublay group. Recurrence at 6 months was zero in both groups. Overall complication rates were higher in the onlay group. Statistical significance was analyzed using chi-square and t-tests, with p-value <0.05 considered significant. Conclusion: Sublay mesh repair offers superior surgical outcomes with lower postoperative complications and shorter hospitalization compared to onlay mesh repair for ventral hernia. Based on this comparative analysis, sublay technique may be recommended as a preferred approach in elective ventral hernia repairs.
