ABSTRACT

Objective: To compare the Lichtenstein technique with an elliptical dome-shaped mesh (EDSM) in terms of post-surgical pain.
Setting: Ambulatory care medical unit #55 of the Mexican Social Security Institute (IMSS, for its initials in Spanish) of the city of Leon, Gto, Mexico.
Design: Controlled clinical randomized double-blind trial.
Statistical analysis: Chi square, Logrank-KaplanMeier test, variance analysis of repeated measures with grouping factor, Cox risk analysis.
Material and methods: Ninety patients with an inguinal hernia were randomly assigned to two groups: EDSM and Lichtenstein, Follow-up at the first week, and at one, three, and six months. Studied variables: pain intensity through a visual analog scale, pain frequency, use of analgesics, type of dysesthesias, complications, and recurrence at six months.
Results: Groups were similar in terms of general characteristics. We found a smaller proportion of patients with pain in group EDSM (χ2 = 7.28, p = 0.007). EDSM showed less pain intensity (F = 22.37, p = 0.000003). There were no differences in surgical time, use of analgesics or frequency of dysesthesias, except for the first week. The surgical technique proved to be determinant for pain in the risk analysis (p = 0.009). One recurrence occurred in the EDSM group.
Conclusions: EDSM is a surgical technique as effective as the Lichtenstein and produces less post-surgical pain.
