A Survey of 366 Sites of Inguinal Hernia Based on the Japanese Hernia Society (JHS) Classification in Kameda General Hospital

In 2009, The Japanese Hernia Society (JHS) classification was revised. We surveyed 366 patients who underwent surgery for inguinal hernia in three years in our hospital. (Methods) We analyzed the date based on a frequency of each classification type of all sites, male and femal, and the recurrence cases. (Results) We show below a number and frequency of the JHS classification type of all sites. Ⅰ-1 : 48 sites (13.1%),Ⅰ-2 : 177 sites (48.4%), Ⅰ-3 : 39 sites (10.7%), Ⅱ-1 : 25 sites (6.8%), Ⅱ-2 : 12 sites (3.3%), Ⅱ-3 : 18 sites (4.9%), Ⅲ : 33 sites (9.0%), Ⅳ : 13 sites (3.6%), Ⅴ : 0 sites(0%). Ⅰ-1 ratio was higher than expected because it included a judgment mistake. In the recurrence case, Ⅱ-1 types and type Ⅲ were observed a lot. In the woman case, type Ⅲ accounted for about 40%. For type Ⅰ, it is necessary that the revised contents will be clearly known . TypeⅡ-1 and Ⅲ are important classification types from the viewpoint of prevention of the recurrence. In female cases, we should al-ways check for the presence of enlarged femoral ring because the type Ⅲ is often in the female inguinal hernia.
