Abstract

Purpose

We are to describe the incidence and accordance rate of hernia type in synchronous bilateral and metachronous contralateral inguinal hernia.

Methods

We retrospectively reviewed the medical records of 625 adult patients who underwent inguinal hernia repair by a single surgeon at our institute between November 2001 and October 2008. We divided the patients into 3 groups; Synchronous bilateral inguinal hernia group (SH), Metachronous contralateral inguinal hernia group (MH) and Unilateral inguinal hernia group (UH) and analyzed patients' general clinical features and outcomes.

Results

Male patients numbered 578 (92.5%) and female patients numbered 47 (7.5%), so the male to female ratio was 12.3:1. Each number of SH and MH were 49 (7.8%) and 59 (9.4%). In MH, the mean interval of counterlateral hernia development following ipsilateral hernia repair was 8.9 years and 20 (33.9%) were developed in a 3-year period. And the incidence of right hernia development after repair of left hernia predominated over left hernia development after repair of right hernia by a ratio of 1.27:1. Accordance rate of hernia type in both sides was 83.8% in SH and 91.2% in MH.

Conclusion

The incidence of SH and MH were each 7.8% and 9.4% and accordance rate of hernia type is very high in SH and MH. In MH, many patients (33.9%) developed in 3 years after ipsilateral hernia repair. In this study, patients have high accordance rate of hernia type in both sides and indirect type is dominant, especially in MH.
