Direct inguinal hernias | Hernia sac doesnt enter canal but pushes through wall common in elderly males acquired |
femoral hernia | common in women very small, painful high chance of strangulation |
difference between inguinal and femoral | femoral-hernia sac located above and lateral to pubic tubercle inguinal-below and medial to pubic tubercle |
umbilical hernia | Congenital/Omphalocoele-failure of retraction of intestinal loops Acquired-breakdown of scar tissue |
Incisional | Follow surgery. Causes include infection, poor surgical repair, poor surgical incision |
