Classification systems for groin hernias

Abstract

All groin hernia classifications are somewhat arbitrary and artificial. Currently, there is no consensus among either general surgeons or hernia specialists as to a preferred system. A survey by Zollinger in 1998 of hernia specialists in North American and Europe showed, that although the Nyhus, Gilbert, and Schumpelick-Arit systems were commonly used, the majority of these specialists still used the traditional classification for groin hernias. It is apparent that only the traditional classification of groin hernias has stood the test of time. As stated by Fitzgibbons, "the primary purpose of a classification system for any disease is to stratify for severity so that reasonable comparisons can be made between various treatment strategies." Given the multiplicity of operative techniques and approaches for the repair of groin hernias, it appears that no one classification system can satisfy all. With time, it is likely that we surgeons will settle upon a given operation for a specific type of inguinal hernia. For that given operation to be accepted as proven best, however, it is essential the competing operations be applied to simliar (classified) groups of groin hernia patients.
