In endoscopy, the doctor places a long, thin, flexible tube (called an endoscope) down the patient's throat and into the stomach and duodenum. A camera and light on the tip of the endoscope enables the doctor to check for abnormalities. Tiny samples may be taken to check for H. pylori bacteria, a cause of many peptic ulcers. If a bleeding ulcer is found, it may be sealed with a burning tool (cauterized) during the procedure.

Upper GI Series

An upper GI series was the standard method for diagnosing peptic ulcers until endoscopy and tests for detecting H. pylori were introduced. In an upper GI series, the patient drinks a solution containing barium. X-rays are then taken, which may reveal inflammation, active ulcers, or deformities and scarring due to previous ulcers. Endoscopy is more accurate than an upper GI series, although it is also more invasive and expensive.

Other Laboratory Tests

Stool tests may show traces of blood that are not visible to the naked eye, and blood tests may reveal anemia in those who have bleeding ulcers. If Zollinger-Ellison syndrome is suspected, blood levels of gastrin should be measured.
