27

What nerve is usually injured with laparscopic hernia repair?

genitofemoral

28

What are the two branches of the genitofemoral nerve and what do they do?

genital branch - cremasteric (motor) and scotum (sensory); femoral branch - uppler lateral thigh (sensory)

29

What is the tx for cord lipomas?

should be removed

30

What is in the trapezoid of doom in laparoscopic hernia repairs?

femoral branch of genitofemoral nerve, lateral cutaneous nerve and femoral artery

What are the boundaries of the femoral canal?

Cooper's ligament, inguinal ligament and femoral vein

5 years

37

Is the risk of incarceration of umbilical hernia in children or adults?

Adults

What type of hernia goes through the greater sciatic foramen and has a high rate of strangulation?

Sciatic hernia

43

What is the tx for obturator hernia?

operative reduction, may need mesh, check other side for similar defect. diagnosis usually made at the time of surgery for small bowel obstruction

44

What type of hernia is the most likely to recur? what is the most common cause of this hernia?

incisional, inadequate closure

45

What Fothergill's sign and what can it indicate?

abdominal wall mass more prominent and painful with flexion of the rectus muscle
