Gastrointestinal on PLAB 1
Gastrointestinal questions follow patients from the GP surgery to the surgical take: dyspepsia, change in bowel habit and jaundice in primary care, then GI bleeding, pancreatitis and the acute abdomen in hospital. Many questions test the urgent referral rules for suspected cancer.

- Learn the NICE suspected-cancer referral criteria by age and symptom. Questions often hinge on whether a patient meets the two-week pathway.
- For the acute abdomen, know the first-line imaging for each presentation.
- Pair each liver test pattern (hepatitic or cholestatic) with its likely causes.
Common questions
Is surgery tested on PLAB 1?
Yes, at the level of a Foundation doctor: recognising surgical emergencies, choosing the first investigation, resuscitation, and knowing when to call the surgical team. You are not asked to perform operations.
How do I revise suspected cancer referral?
Use the NICE guideline on suspected cancer (NG12). Learn the age and symptom thresholds for each GI cancer, then test yourself with scenario questions where the patient only just meets, or only just misses, the criteria.
