Incisional hernia is the most common complication of laparotomy that requires reoperation. The present study was conducted to compare composite versus prolene mesh in intraperitonealonlay repair for ventral hernia. Materials & Methods:50 patients of ventral hernia of both genders were divided into 2 groups. In group I, patients underwent intraperitonealonlay mesh repair for ventral hernia using composite mesh and in group II, patients underwent intraperitonealonlay mesh repair for ventral hernia using prolene mesh. Time taken for surgery was measured. Post op pain was assessed by visual analogue scale. Post op complications like hematoma, seroma, bleeding, and suture site infection etc. was recorded. Results: Group I had 15 males and 10 females and group II had 13 males and 12 females. The duration of surgery was 131.2 minutes in group I and 124.2 minutes in group II, hospital stay was 5.7 days in group I and 6.5 days in group II and post- operative pain was 4.8 in group I and 5.3 in group II. The difference was significant (P< 0.05). Complications were suture site infection in 1 in group I and 2 in group II, seroma 2 in group I and 1 in group II, hematoma 1 in group I and 4 in group II and bleeding 3 in group I and 5 in group II. The difference was significant (P< 0.05). Conclusion: The onlay mesh repair for ventral hernia using the composite mesh was found to be superior to the prolene mesh.
