Epigastric pain typically before meals or at night.
Relieved by eating or drinking milk.
50% are asymptomatic - others experience recurrent episodes.

22

24

What must be stopped 2 weeks before an upper GI endoscopy.

PPIs.

25

When must you measure gastrin concentrations when off of PPIs.

If you suspect Zollinger-Ellison syndrome.

30

What are the symptoms of gastric ulcers. (4)

Asymptomatic.
Epigastric pain.
Pain related to meals and relieved by antacids.
Weight loss.

31

How do you diagnose gastric ulcers. (4)

Upper endoscopy to exclude malignancy.
Multiple biopsies from ulcer rim and base (histology, H.pylori).
Brushings (cytology).
Repeat endoscopy (eg if perforation or bleeding) to check healing.

32

What aspects are involved in the treatment of PUD. (4)

Lifestyle changes.
H. pylori eradication.
Drugs to reduce acid.
Drug-induced ulcer treatment.

33

What are the lifestyle changes in the treatment of PUD. (4)

Stress control.
Reduce alcohol.
Stop smoking.
Avoid aggravating foods.

34

How is H.pylori eradicated.

Triple therapy is effective in 80-85% of cases.

35

What drugs are used to reduce acid. (2)

PPIs (lansoprazole).
H2 antagonists (ranitidine).

36

How do you treat drug induced ulcers. (2)

Stop drug if possible.
PPIs may be best for treating and preventing GI ulcers and bleeding in patients on NSAID or antiplatelet drugs.
