Background: Onlay and Sublay Hernioplasty for
ventral hernias are commonly performed techniques. However, it remains unclear
which technique is better.
Aim: To compare the outcome of
on-lay versus sublay hernioplasty in ventral hernia presenting in our setup.
Methods: This randomized controlled trial was done at surgical unit IV of Services Hospital Lahore. The duration of this study
was on year i.e., from Feb, 2017 till Jan 2019. An approval was taken from hospital ethical
committee. Consecutive sampling technique was used. Patients were randomly divided
in two equal groups using random number tables in Group A: Onlay hernioplasty and
Group B: Sublay hernioplasty. All
procedures were performed by a single operating team to control bias. Patients
were followed up 1st, 2nd, and 4th weeks for
mean age of cases in this study was 39.47±11.24 years and there were 33(55%)
male and 27(45%) female cases with higher male to female ratio. During first
week after surgery in On-lay and Sub-lay group seroma was seen in 9(30%) and
2(6.7%) respectively, p-value = 0.020. After 2nd week post
operatively seroma was seen in 6(20%) of the cases in onlay group and 1(3.3%)
of the sublay group, p-value = 0.044. And at 4th week follow up, seroma
was seen in 6(20%) of the cases in Onlay mesh group and 1(3.3%) of sublay mesh group,
Conclusion: In the light of results, we found that Sublay mesh repair has better compliance
as lesser seroma formation and low recurrence rate.
