Why were the biopsies taken from the antrum?

As RUT results are significantly affected by the use of acid suppression and antibiotic therapies, biopsies for RUT should be taken from both the gastric antrum and body to minimise false negative results.

What is a biopsy of the antrum?

A gastric tissue biopsy and culture are laboratory tests that examine stomach tissue. These tests are typically carried out to determine the cause of a stomach ulcer or other troublesome stomach symptoms. “Gastric tissue biopsy” is the term used for the examination of tissue removed from your stomach.

What do biopsies from endoscopy show?

Your doctor may use an endoscopy to collect tissue samples (biopsy) to test for diseases and conditions, such as anemia, bleeding, inflammation, diarrhea or cancers of the digestive system.

What is the purpose of an antrum?

EXPERIMENTAL proof has been secured supporting the postulate of Edkins that the gastric phase of secretion is mediated by the antrum of the stomach, which functions as an endocrine organ, releasing the gastric secretory stimulant, gastrin, under appropriate conditions.

What is abnormal mucosa in the antrum?

These abnormalities are located at the antrum of the stomach at variable distances from the pylorus and are composed of mucosa which encloses a membrane of submucosa without involvement of muscularis or serosa. They may be congenital in origin or secondary to chronic peptic ulcer disease.

What does it mean if a biopsy is positive?

At the most basic level, these test results are expected to be one of two kinds: positive, meaning the condition (or cancer) being sought – or an abnormality – is present; or negative, meaning the condition has not been detected. Biopsies provide much more information than just the presence or lack of cancerous cells.

How many biopsies are taken during endoscopy?

Currently, 6 to 8 biopsies are recommended for diagnosis of a suspected malignant lesion. However, multiple biopsies may result in several problems, such as an increased risk of bleeding, procedure prolongation, and increased workload to pathologists.

What causes inflammation of the antrum?

They’re usually formed as a result of inflammation caused by the bacteria H. pylori, as well as from erosion from stomach acids. Peptic ulcers are a fairly common health problem.

What is the antrum in the stomach?

Antrum: the lower portion (near the small intestine), where the food mixes with gastric juice. Pylorus: the last part of the stomach, which acts as a valve to control the emptying of the stomach contents into the small intestine.
