An Experience to Compare the Outcome of Sublay Versus Onlay Mesh Repair in Venteral Hernias

Abstract

Objective: To compare the recurrence and complication rates in subaly and onlay mesh repair in primary and secondary ventral hernias. Methods: This prospective randomized controlled comparative and interventional study was conducted at Surgical Unit 11I of Peoples University of Medical & Health Sciences for Women Nawabshah and Jinnah Medical Center Nawabshah, from January 2014 to December 2015. Sixty patients were randomly selected having paraumblical, epigastric hernia of different sizes and recurrent ventral hernias. Synthetic polypropylene mesh sublay and onlay was used to repair. Follow up time was about two years, monthly for six months and 6 monthly up to years. Results: In this study we include 60 patients: age range was 20 to 76. and mean age 46.2± 14.5 -years. Most of the patients ( 63.3%) having age of25 to 50 -years. 50 ( 83.3%) were female. Out of 60 patients 30 (50%) were included in both groups. Mean Age of patients was 45.25±6.45 and 42.30±5.46 years in group A and B respectively. Predisposing factors were overweight 28 (46.7%) and Obese patients 11 (18.3%) with a mean BNII 32.6±6.3, whereas 21 patients (35'h) were of normal weight with mean BIM 21.3±3.6 p-value of(<0.002 ). Conclusion: Sublay mesh repair is superior, in respect of recurrence rates, surgical site infection, and seroma formation as compared to Onlay mesh repair for ventral hernias. However the procedure is demanding and difficult to perform has excellent results and recommended to do this procedure.
