Stomach biopsy, to test for gastritis and other conditions [27] The OLGA staging frame of chronic gastritis on histopathology. Atrophy is scored as the percentage of atrophic glands and scored on a four-tiered scale. No atrophy (0%) = score 0; mild atrophy (1–30%) = score 1; moderate atrophy (31–60%) = score 2; severe atrophy (>60%) = score 3.
Atrophic gastritis is a process of chronic inflammation of the gastric mucosa of the stomach, leading to a loss of gastric glandular cells and their eventual replacement by intestinal and fibrous tissues. As a result, the stomach's secretion of essential substances such as hydrochloric acid, pepsin, and intrinsic factor is impaired, leading to ...
267,500 (2015) [6] Peptic ulcer disease is a break in the inner lining of the stomach, the first part of the small intestine, or sometimes the lower esophagus. [1][7] An ulcer in the stomach is called a gastric ulcer, while one in the first part of the intestines is a duodenal ulcer. [1] The most common symptoms of a duodenal ulcer are waking ...
Gastric antral vascular ectasia. Gastric antral vascular ectasia (GAVE) is an uncommon cause of chronic gastrointestinal bleeding or iron deficiency anemia. [1][2] The condition is associated with dilated small blood vessels in the gastric antrum, which is a distal part of the stomach. [1] The dilated vessels result in intestinal bleeding. [3]
Helicobacter pylori colonizes the stomach for decades in most people, and induces chronic gastritis, a long-lasting inflammation of the stomach. In most cases symptoms are never experienced but about 10–20% of those infected will ultimately develop gastric and duodenal ulcers, and have a possible 1–2% lifetime risk of gastric cancer.
Stomach diseases include gastritis, gastroparesis, Crohn's disease and various cancers. [1] The stomach is an important organ in the body. It plays a vital role in digestion of foods, releases various enzymes and also protects the lower intestine from harmful organisms. The stomach connects to the esophagus above and to the small intestine below.
Gastroenterology. Ménétrier disease is a rare, acquired, premalignant disease of the stomach characterized by massive gastric folds, excessive mucus production with resultant protein loss, and little or no acid production (achlorhydria). The disorder is associated with excessive secretion of transforming growth factor alpha (TGF-α). [1]
Cancer. Esophagitis, also spelled oesophagitis, is a disease characterized by inflammation of the esophagus. The esophagus is a tube composed of a mucosal lining, and longitudinal and circular smooth muscle fibers. It connects the pharynx to the stomach; swallowed food and liquids normally pass through it.
