1

What is the aim of population screening?

To detect pre-malignant adenomas/early cancers in the general population

2

What two modalities of testing are most commonly used to screen populations for bowel cancer?

Faecal occult blood test (FOBT)
Faecal immunochemical test (FIT)

3

Other than the general population, what groups would screening regularly take place in?

High risk groups

4

Give an example of a group with a high risk of developing colorectal cancer

Heritable conditions e.g. FAP/HNPCC
Inflammatory bowel disease
Family history
Previous adenomas/colorectal cancer

5

Give two types of colorectal problems which might require surgery

Tumour
Inflammation
Degeneration
Abnormal function
Congenital

6

Give an example of an inflammatory colorectal condition which might require surgical treatment

Ulcerative colitis
Crohn's disease

7

Give an example of a degenerative colorectal condition which might require surgical treatment

Diverticular disease

8

Give an example of a colorectal condition causing abnormal function which might require surgical treatment

Constipation
Incontinence
IBD

9

Give an example of a congenital colorectal condition which might require surgical treatment

Atresia
Hirschsprung's disease

10

What investigations would you do if suspecting a colorectal condition?

Endoscopy
Colonoscopy and biopsy
Cross sectional imaging - CT/CT colonography
MRI

11

What should be considered before surgery is carried out to correct a colorectal condition?

Resection
Restoration of continuity
Preservation of function
Faecal diversion

12

What peri-operative care should be given to a patient undergoing colorectal surgery?

Informed consent
DVT prophylaxis
Antibiotics prophylaxis
Possible bowel preparation

13

What properties doe the bowel anastomosis need to have in order for surgery to be successful?

Tension free
Well perfused
Well oxygenated
Clean surgical site
Acceptable systemic state

14

What are the surgical options for colorectal conditions?

Faecal diversion
Ileal pouch

15

What is involved in a faecal diversion surgery?

Colostomy/ileostomy - stoma created

16

What is involved in ileal pouch surgery?

Creation of a pouch of small intestine, following surgical removal of colon and rectum, to recreate the removed rectum - 2 or more loops of small intestine sutured or stapled together to form a reservoir for stool which is then attached to the anus.

17

What are the possible complications of colorectal surgery?

Anaesthetic related
Bleeding
Sepsis
Venous thromboembolism
Anastomotic breakdown
Small bowel obstruction
Wound hernia
