A Prospective Comparative Clinical Trial of Onlay versus Sublay Mesh Repair for Treatment of Ventral Hernia

Abstract

Introduction: This randomized clinical study was done at Sharda Hospital on patients admitted to the Surgery ward with Ventral hernias after taking an Informed consent. Patients were investigated as a part of the pre-operative evaluation and Hernia Repair surgery is done as planned. Aims & Objective: To compare the onlay vs sublay mesh repair techniques for ventral hernias in patients coming to Sharda hospital for 1) post-operative pain (vas) 2) Duration of hospital stay, 3) Time required to return to work 4) Complications (Seroma, Hematoma, Wound Infection, Recurrence.) Materials and Methods: Patients reporting to General surgery OPD of SMS&R, S. hospital, G. N. with Ventral hernia were included in the study. Patients will be randomized into two groups: -group A, patients operated upon by Onlay mesh repair, and group B, patients by Sublay component separation repair. Patients followed up for- 1) post-operative pain (day 2, day 7, 1 month, and 3 months) using VAS, 2) mean hospital stay (in days), 3) return to basic activity (in days), and 4) complications including Seroma, Hematoma, SSI and recurrence. Result: Data collected and entered in the proforma, tabulated and analyzed using software package for statistical analysis (SPSS2015). Seroma, hematoma, superficial skin necrosis, SSI, hospital stay, & return to normal activities was more in onlay than in sublay repair. Conclusion: Sublay mesh repair was found to be excellent in terms of short-term results with minimal morbidity. It resulted in fewer complications and no recurrence was noted. Seroma, hematoma, superficial skin necrosis, SSI, hospital stay, & return to normal activities was relatively more in onlay mesh repair than sublay mesh repair.
