3- Umbilical hernia.
4- Other abdominal hernia.
Internal:
1- Diaphragmatic hernia.
2- Hernia in lesser sac.

31. External Hernia
1- Inguinal (indirect & direct).
2- Femoral hernia.
3- Umbilical hernia (congenital,
infantile and adult paraumbilical).

2- Weakness of abdominal wall
(obesity, pregnancy, scar & nerve
injury).
3- Increased intra-abdominal pressure
(chronic straining & Abdominal
swelling).

peritoneum and organs except
pancreas).
4- Coverings differs according
type of hernia.
