COMPARISON OF ONLAY AND SUBLAY MESH HERNIOPLASTY IN PATIENTS WITH VENTRAL HERNIA IN TERMS OF SURGICAL SITE INFECTION AND SEROMA FORMATION

Abstract

Objective: To compare and sublay mesh hernioplasty in patients with ventral hernia in terms of surgical site infection and seroma formation.

Study Type: Randomized Controlled Trail

Study Place and Duration: From January 2024 to June 2024. Department of General Surgery, Combined Military Hospital, Lahore

Material and methods: There were 76 individuals who participated in the study, of both sexes, ranging in age from 18-70 years, undergoing surgery to correct a ventral hernia. After informed written consent, demographic data was recorded. Group 1 and Group 2 were equal in number. Thirty-eight patients in Group 1 underwent onlay mesh technique, while thirty-eight patients in Group 2 underwent sublay method of hernia repair. A number of outcomes, including wound infection and seroma development were noted in order to compare the two groups' performance. SPSS 25.0 was used to analyze the data. Mean and Standard Deviation was calculated for quantitative variables and frequency and percentage was calculated for qualitative variables. The Chi-square and student t-tests were used. The threshold for a meaningful difference was set at p ≤0.05.

Results: Both groups were comparable in terms of age, BMI and gender. During follow up, surgical site infection was observed in 26.3% patients of group A and 5.3% patients of group B (p=0.47). Seroma formation was observed in 21.1% patients of group A and 2.6% patients of group B (p=0.028).

Conclusion: In comparison to on-lay mesh, surgery done by the sub-lay mesh method for repair of ventral hernias was proved to be more safe, effective, and required a shorter hospital stay in terms of wound infection, seroma formation, and discomfort following the procedure.
