A comparison analysis of post-operative pain in 1 month after operation

Abstract

Objective : To compare post-operative pain in 1 month after operation between nonmesh
(Bassini) hernia repair and Prolene mesh primary hernia repair.
Material and Method : This research was a cohort study about the post-operative pain from
hernia repair from 162 patients who were operated by a single surgeon in a
Rural Hospital from 2007 to 2012. The patients was divided into 2 groups.
Each consisted of 81 patients. The first group received Bassini h e r n i a
repair while the latter received Prolene mesh. Spinal block was used to
reduce pain. Patients would receive NSAID to soothe post-operative pain.
A Visual Analogue Scale (VAS) was used to evaluate the severity of pain
one month after operation.
Result : Twenty nine point five percent of the patients who received Bassini operation
had VAS score of more than 5 (the average of VAS was 2.0) while only
24.6 percent of patients who received Prolene mesh had the same score (the average of 1.7). There was no statistical difference between these 2
groups (Chi-square, (p=0.32 ; 95% CI-0.08 - + 0.23).
Conclusion : There was no statistical difference in the severity of post-operative pain
between the 2 methods used in hernia repair. The choices of method is
not the main factor in determining the pain from operation but the control
of pain both pre and post operation was more significant.
