Description |
1 |
Indirect hernia with normal internal ring; typically seen in infants, children, and small adults |
2 |
Indirect hernia in which the internal ring is enlarged without impingement on the floor of the
inguinal canal; hernia does not extend to scrotum and inferior epigastric vessels are not displaced |
3A |
Direct inguinal hernia; size is not taken into account |
3B |
Indirect hernia that has enlarged enough to encroach on the posterior inguinal wall; indirect
sliding or scrotal hernias are usually placed in this category because they are commonly
associated with extension to direct space; these also include pantaloon hernias |
3C |
Femoral hernia |
4 |
Recurrent hernia; modifiers A, B, C, and D are sometimes added to type 4, corresponding
to direct, indirect, femoral, and combined |
