Physical examination and
patient history The diagnosis of peptic ulcers is rarely made on the basis of a physical examination alone. The only significant finding may be mild soreness in the area over the stomach when the doctor presses (palpates) it. The doctor is more likely to suspect an ulcer if the patient has one or more of the following risk factors: Male sex Age over 45 Recent weight loss, bleeding, recurrent vomiting, jaundice, back pain, or anemia History of using aspirin or other NSAIDs History of heavy smoking Family history of ulcers or stomach cancer. Endoscopy and imaging studies An endoscopy is considered the best procedure for diagnosing digestive ulcers and for taking samples of stomach tissue for biopsies. An endoscope is a slender tube-shaped instrument that allows the doctor to view the tissues lining the stomach and duodenum. Duodenal ulcers are rarely malignant. If the ulcer is in the stomach, however, the doctor will take a tissue sample because 3–5% of gastric ulcers are malignant. Radiological studies are sometimes used instead of endoscopy because they are less expensive, more comfortable for the patient, and are 85% accurate in detecting malignancies. Laboratory tests Blood tests Blood tests usually give normal results in ulcer patients without complications. They are useful, however, in evaluating anemia from a bleeding ulcer or a high white cell count from perforation or penetration. Serum gastrin levels can be used to screen for Zollinger-Ellison syndrome. Tests for Helicobacter pylori It is important to test for H. pylori because almost all ulcer patients who are not taking NSAIDs are infected. Noninvasive tests include blood tests for immune response and a breath test. In the breath test, the patient is given an oral dose of radiolabeled urea. If H. pylori is present, it will react with the urea and the patient will exhale radiolabeled carbon dioxide. Invasive tests for H. pylori include tissue biopsies and cultures performed from fluid obtained by endoscopy. |
