Peptic ulcer disease
Pathophysiology
Most peptic ulcers are in the duodenum.[1]
Diagnosis
History and physical examination
One study found that the best predictions of abnormal investigations were: history of an ulcer, age 50 or more, pain better with food or milk, pain occurs < one hour after eating. [2]
If the ulcer is in the duodenum, the pain may be relieved by eating; whereas eating may exacerbate the pain of a gastric ulcer.[3][4][1][2] As most ulcers are duodenal, in general eating relieves ulcer pain.
Some patients may have chest symptoms such as heartburn or reflux.[5][6]
On physical examination, pallor of conjunctiva, nail-bed or palmar crease, or the absence of nail-bed blanching are predictive of significant anemia (hemoglobin less than 12 gm/dl).[7]
Laboratory testing
The accuracy of the H. pylori breath test for detecting peptic ulcer disease is:[8]
- sensitivity 93%
- specificity 60%
Prevention
Users of nonsteroidal anti-inflammatory (NSAID) medications
Patients with a history of bleeding ulcer have a 26% rate of ulcers with NSAIDs.[9] Patients with H. pylori have 2.5 risk of an ulcer on NSAIDs.[10]
For patients starting long-term NSAIDs, screening for H. pylori with a breath test among patients with prior ulcer or dyspepsia and treating positive patients reduced subsequent rate of ulcers.[11] [12]
For patients who must take NSAIDs, proton pump inhibitors may be effective in preventing dyspepsia.[13]
