3 nerves -
3 other things - vas, pampiniform plexus, lymphatic
risk factors for hernia
fat
age
chronic cough
collagen disorder
inguinal hernia can be either direct or indirect, outline each
indirect - through deep inguinal ring
direct = through anterior surface (ligaments)
indirect hernia would be medial to inferior epigastric vessels
false
medial = direct
lateral = indirect

indirect
t/f all hernias will require surgery
false
most likely to frail for surgery
30% postop develop chronic pain

anterior - internal oblique/ apponeurosis of external oblique
posteior -transversalis fascia and conjoint tendon
superior - internal oblique and transveruss abdominis

2 types of epigastric hernias
paraumbilical (just beside umbilicus)
