Q

Epigastric hernias are not commonly large defects in the linea alba and generally only contain abdominal fat. What stops the bowel being present in epigastric hernias?

1 - xiphoid process
2 - rectus abdominus
3 - falciform ligament
4 - pancreas

A

3 - falciform ligament

17
Q

Epigastric hernias can be symptomatic of asymptomatic, depending on the size of the defect. If a patient presents with symptoms, which of the following is NOT a common symptom?

1 - bowel obstruction
2 - palpable lump
3 - pain

A

1 - bowel obstruction

  • bowel not generally involved due to falciform ligament
18
Q

Which of the following is NOT commonly included as a differential in patients with a suspected epigastric hernia?

1 - divarication of the rectus / diastsis
2 - intra-abdominal mass
3 - bowel obstruction
4 - skin lesion

A

3 - bowel obstruction

19
Q

Generally epigastric hernias are managed conservatively unless they enlarge or become symptomatic

A
20
Q

How big are epigastric hernias generally?

1 - <0.5cm
2 - <1cm
3 - <2cm
4 - <4cm

A

1 - <0.5cm

21
Q

What is an incisional hernia?

1 - a patients abdomen is punctured with a sharp object
2 - congenital weakness in linea alba
3 - weakness of abdomen due to previous surgery
4 - defect causes during embryological development

A

3 - weakness of abdomen due to previous surgery

22
Q

Following surgery to the abdominal wall the strength of the abdominal wall is always reduced. What % of the original wall strength is the abdomen following surgery?

1 - 0.7%
2 - 7%
3 - 37%
4 - 70%

A

4 - 70%

  • sutures can cut through tissue leaving a defect
23
Q

Wounds closed under tension is a risk factor for an incisional hernia. Why does closing under tension increase the risk of an incisional hernia?

1 - damages peritoneum
2 - cause necrosis of tissue and tissue weakens
3 - can damage organs
4 - skin is unable to heal properly

A

2 - cause necrosis of tissue and tissue weakens

24
Q

In addition to closing a wound under tension, there are multiple risk factors for an incisional hernia. Which of the following is NOT a risk factor?

1 - wound infections
2 - gender
3 - diabetes
4 - immunosuppression (including steroids)
5 - obesity
6 - midline incisions (up to 20% for midline laparotomies)
7 - smoking

A

2 - gender

  • diabetes and immunosuppression (including steroids) can cause poor wound healing and increase risk of infection
