Classification of Inguinal Hernias

Abstract

The results of inguinal hernia repair are related to the location of the hernial orifice and the size of the fascial defect. Recurrence rates after operation on a large direct hernia are about five times higher than those after repair of a small indirect hernia. Classification of inguinal hernias is a prerequisite for planning, conducting, and discussing clinical trials on this subject. Precise documentation of location and size of the defect of the abdominal wall is crucial information for critical analysis of recurrence rates when evaluating different surgical techniques. It serves the same purpose as the TNM classification of malignant tumors, making clinical studies reproducible and therapeutic regimens comparable.1
