Gastro-duodenal ulcer (or peptic ulcer) is a lesion, located on the digestive mucosa that is in contact with gastric acid secretions, localized to the stomach or duodenum. This same type of ulcer can be found on the lining of the esophagus.
The three diagnosis and results are:
1. Upper digestive endoscopy confirms the diagnosis of ulcer of the stomach or duodenum
Performed under local or general anesthesia by a gastroenterologist doctor, upper gastrointestinal endoscopy can visualize the inside of the stomach and duodenum using a small camera.
If an ulcer is present in one of these organs, it appears as a crater with regular, raised, and red edges. This crater is dug in the mucosa and reaches the muscular layer in depth.
2. A marked urea breath test may be useful for the diagnosis of <em>H Pylori </em>infection, but is primarily used to control the eradication of the bacterium after treatment. A positive marked urea breath test means that there's still <em>H pylori</em> producing urease to degrade urea.
3. when the patient has already taken antisecretory drugs (proton pump inhibitors) or has recently taken antibiotics that distort the results of respiratory tests or biopsy tests, a blood test of specific antibodies is very useful to diagnose Helicobacter Pylori infection. If it's positive it means that the immune system is still active against <em>H pylori.</em>
