Types of hernia
Usually hernias are described by where the hole is in the abdominal wall. So an inguinal hernia occurs in the inguinal or groin region. An umbilical hernia – at the umbilicus or navel, and an epigastric hernia occurs in the upper abdomen – known as the epigastrium.
Inguinal hernias are the commonest type of hernia. They occur in the groin (or inguinal region), mainly in men. They are much less common in women.
“Ventral hernias” – this term is used a lot in America. Anatomically our front is the ‘ventrum’ and our back is our ‘dorsum’ (dorsal fin of a shark). So epigastric hernias, on the front of the abdomen, are also called ventral hernias. It can get a bit confusing when some doctors refer to diastasis or divarication, or incisional hernias as ventral hernias – and I will explain more later.
A hernia that has never been operated on before is a primary hernia.
Recurrent hernias are hernias that have come back after a previous repair
An incisional hernia is a hernia through a previously made incision ( for another reason – eg an abdominal operation fro something else).
And note – if a previous hernia repair opens up again it is called a recurrent hernia not an incisional hernia.
2) Diastasis (not a true hernia)
3) Supra-umbilical hernia
4) Umbilical hernia
5) Incisional hernia
6) Scar (previous inguinal hernia op)
7) Recurrent inguinal hernia
8) Spigelian hernia (rare)
9) Inguinal hernia
10) Femoral hernia
11) Pubic bone
12) Inguinal ligament – groin skin crease
Two confusing hernias :-
1. A hiatus* hernia is where the stomach moves upwards, out of the abdomen, through a normal hole in your diaphragm into the chest cavity. The normal hole is where the oesophagus (gullet) passes from your mouth into your stomach.
* (hiatus = hole in Greek)
2. Confusingly, (particularly in continental Europe) the word hernia is used to describe a slipped disc in the back. That’s because the word hernia really means something popping out of the space where it is supposed to be, into another area or space. So in the back, the inside of one of the cushions or discs that lie in between the individual vertebrae (bones of our spine) slips (or ‘herniates’) through its covering, and presses on a nerve. NOTHING at all to do with the hernias we are talking about.
