Comparison of two layered prolene mesh hernia repair versus conventional lichtenstein mesh repair for postoperative pain in inguinal hernias: a randomized control trial

Abstract

Background: Inguinal hernia surgery is the most frequently performed operation in general surgery and so even modest improvements in clinical outcomes are important. This study has been taken as an initiative to compare the post-operative pain after conventional Lichtenstein’s meshplasty against two layered prolene mesh Hernia repair. Methods: This is a randomized control study done in our hospital over period of one year between December 2014 to December 2015. In this study out of 60 patients who underwent mesh repair 30 underwent two layered prolene mesh Hernia repair and 30 underwent conventional Lichtenstein mesh repair. All collected was tabulated and statically analyzed by using SPSS software. Results: All patients in both groups were male patients. Majority of the hernias were of the right side. Maximum pain score was seen at 2 weeks and minimum pain at 12 weeks. Pain at 2 weeks was 5.7±0.56 in MPHS group and 5.9±0.69 in CLMR group. At 12 weeks it was 1.0±0.30 and 1.1±0.35 respectively in both groups. The mean reduction of pain from 2 nd to 12 th week was 4.8±0.47 in TLPMR group and 4.7±0.70 in CLMR group. No statistical significant difference was noted as demonstrated by Mann Whitney U test. Wilcoxon signed ranks test also demonstrated that there was no statistically significant difference between the 2 groups. Conclusions: There is apparent advantage in the use of two layered prolene mesh repair over other conventional mesh repairs.
