26
Q

What are the three indications for laparoscopic repair?

A
  • Bilateral inguinal hernias

- Comorbid umbilical hernias

27
Q

What are the indications for watchful waiting of inguinal hernias?

A

If pt has CV or pulmonary comorbidities, or lifts a lot for work

28
Q

When is open tissue repair indicated?

A

If infected field

29
Q

Where is the transversus abdominis muscle?

A

Deep to the internal oblique

30
Q

What happens to the posterior rectus abdominis sheath as you go inferiorly?

A

Disappears

31
Q

What are the four types of abdominal wall hernias?

A

Umbilical
Incisional
Epigastric
Spigelian

32
Q

Where do umbilical hernias occur?

A

Umbilical stalk

33
Q

What is the prognosis for congenital umbilical hernias in infants? Acquire in Adults?

A 
Children = will regress
Adults = progress and enlarge
34
Q

What are incisional hernias?

A

Failure of fascial healing

35
Q

What are the risk factors for incisional hernias?

A

Lifting and straining (6 weeks (2 weeks is weakest time)

36
Q

Why are epigastric hernias repaired much more often than other types?

A

These are usually painful

37
Q

Why do you need to mark epigastric hernias when pts are awake?

A

Pt will be too relaxed and it will be hard to find

38
Q

What are Spigelian hernias?

A

Hernias at vascular perforation of the inferior semilunar line

39
Q

What is the semilunar zone?

A

Area where there is no longer fascia behind the rectus abdominus

40
Q

What is a primary repair of an abdominal wall hernia? When are these appropriate (2)?

A

Suture repair of defect.

Good for small hernias and/or contaminated fields

41
Q

What is the problem with primary hernia repairs?

A

high recurrence rate

42
Q

When are mesh reinforced repair contraindicated?

A

Contaminated fields

43
Q

What part of the body do you want to scar over the mesh?

A

Abdominal fascia

44
Q

What is an inlay mesh?

A

Between borders of herniation

45
Q

What is an overlay mesh?

A

Lay over the hernia

46
Q

What is an underlay mesh?

A

Intraperitoneal–behind the hernia

47
Q

What is a retrorectus mesh lay?

A

Between rectus abdominus and its sheath

48
Q

What is the gold standard for mesh laying?

A

Retrorectus lay

49
Q

What are the three characteristics of an ideal hernia repair?

A
  1. Prevent recurrence
  2. Resist infection
  3. Resist intra-peritoneal adhesion
50
Q

What is Diastasis recti? Treatment?

A

Attenuation and widening of the linea alba

Reassure and strengthen

51
Q

What is the appropriate way to reduce the hernia?

A

Push from sides–not on top

52
Q

True or false: incarcerated hernias are not necessarily a surgical emergency

A

True, but should be fixed

53
Q

What are strangulated hernias?

A

Hernias with compromised blood flow

54
Q

What are incarcerated hernias?

A

Hernias that cannot be reduced

55
Q

What are the ssx of strangulated hernias?

A

Redness, warmth, TTP

56
Q

True or false: hernias rarely occur through mesh

57
Q

When should a BMP be ordered with a hernia? CBC? CT?

A 
BMP = If suspect obstruction
CBC = infx
CT = large or recurrent defects
58

derived from?
