Question 3 of 10

3. Question
With reference to the patient described in the previous question, which initial action is the best option?
- Insert an NG tube and aspirate through it to confirm whether the source is upper or lower GI
- Insert a large bore IV cannula and immediately transfuse two units O negative blood
- Insert a large bore cannula and transfuse 1L of gelofusin over 2h
- Insert a large bore cannula and immediately infuse a fluid bolus of saline with a view to arranging blood transfusion
- Arrange urgent colonoscopy

- Upper GI endoscopy
- Colonoscopy
- Nuclear scan
- Capsule enteroscopy
- Angiography
Correct

Incorrect

8. Question

- Colonoscopic therapy will control bleeding in 20% of patients

- Colonoscopy should be delayed until 24h after the acute bleed
- Angiography should be performed prior to colonoscopy to identify the bleeding point
Correct

Incorrect
Question 9 of 10

9. Question
Colonoscopy fails to identify and control the bleeding in the patient from the previous question.

Which is the next best option?
- Systemic vasopressin infusion
- Angiography with super-selective embolisation of bleeding point
- IV pantoprazole 40mg
- Total colectomy
- Technetium labelled red blood cell scanning
Correct

Incorrect
Question 10 of 10

Angiography and super-selective embolisation is performed in the patient from the previous question. Unfortunately, on the following day the bleeding restarts and the patient again becomes unstable.

A decision is made to take the patient to theatre: which one of the following is true regarding surgery in a lower GI haemorrhage?
- Up to 50% of patients require surgery
- Generally surgery is not required even if massive transfusions of red cells are required
