1

What is an abnormal protrusion of a viscus outwith its normal body cavity?

Hernia

2

Name 4 hernias, most common first?

1. Inguinal
2. Umbilical
3. Incisional
4. Femoral

3

What may arise from natural openings or weak areas, caused by stretching or surgical inscision?

Abdominal wall hernias

4

What type of hernias are inguinal, femoral, umbilicus, oesophageal hiatus and obturator?

Natural abdominal wall hernias

5

What are incisional, parastomal, epigastric and paraumbilical herias a type of?

Weak area abdominal wall hernia

6

What is the physiological predisposing factor of abdominal hernias?

Raised intra-abdominal pressure

7

What can pregnancy and obesity lead to?

Abdominal hernias

8

What predisposing factor of abdominal hernias can leads to bilateral inguinal hernia?

Prostatism

9

Can constipation, coughing and heavy lifting cause abdominal hernias?

Yes

10

What may hernias be classified as?

Reducible or irreducible

11

If the hernia is irreducible, what may happen to its contents?

Incarcerated or strangulated

12

What denotes compromise of the blood supply of the contents and its development increases morbidity and mortality?

Strangulation

13

With strangulation hernias, what system is occluded first?

Low pressure venous system, then arterial supply

14

When the arterial supply of a hernia becomes occluded, what can develop?

Gangrene

15

In predisposed patients, to prevent an incisional hernia, what surgical measures are taken?

Tension sutures plus "mass closure" of the linea alba

16

If you have a malignancy are you more likely to develop an incisional hernia?

Yes

17

What two aetiological causes related to after an operation can be predisposing factors for incisional hernias?

Post-operative wound infection
Post-operative wound haematoma

18

What does an ileus do that increases the chance of an incisional hernia?

Raises the intra-abdominal pressure

19

What class of drug can be a predisposing factor for incisional hernias?

Steroids

20

Is a vertical or transverse incision more likely to cause an incisional hernia?

Vertical

21

What type of hernia is common in adult, obese patients?

Paraumbilical

22

What to epigastric hernias arise from?

Congenital weakness of the linea alba

23

What type of hernia usually contains extraperitoneal fat?

Epigastric

24

What type of hernia has a male:female ration of 3:1 and occurs usually in late teens/early adult hood?

Epigastric hernia

25

How do you repair an epigastric hernia?

With sutures or mesh

26

What type of hernia is an umbilical hernia?

Congenital

27

By what age has an umbilical hernia usually resolved, and what action is taken if it hasn't by then?

Age 3, if > 3 operate

28

What male:female ratio does a paediatric inguinal hernia have?

9:1

29

What type of hernias are more common in pre-term and low birth weight infants?

Paediatric inguinal hernias

30

What side are paediatric inguinal hernias commonly found on and what is there a 20% chance of developing?

Right side, developing a contralateral hernia
