| gastric algid malaria | See: algid malaria. Induced malaria, malaria acquired by artificial means, e.g., via blood transfusion, common syringes, or malariotherapy.

| gastric analysis | Measurement of pH and acid output of stomach contents; basal acid output can be determined by collecting the overnight gastric secretion or by a 1-hr collection; maximal acid output is determined following injection of histamine; output is measured by titration with a strong base. (05 Mar 2000) |
| gastric area | One of a number of small polygonal area's, 1-6 mm in diameter, separated by linear depressions on the surface of the mucous membrane of the stomach; they contain the gastric pits, with several gastric glands opening into each pit. Synonym: area gastrica. (05 Mar 2000) |
| gastric arteries | Arteries supplying the stomach along the lesser curvature. See: left gastric artery, right gastric artery. (05 Mar 2000) |
| gastric atrophy | <gastroenterology> A condition in which the stomach muscles shrink and become weak. It results in a lack of digestive juices. Gastritis: Inflammation of the stomach. (12 Dec 1998) |
| gastric balloon | An inflatable device implanted in the stomach as an adjunct to therapy of morbid obesity. Specific types include the silicone Garren-Edwards gastric bubble (gegb), approved by the FDA in 1985, and the ballobes balloon. (12 Dec 1998) |
| gastric branches of anterior vagal trunk | Anterior gastric branches of the vagus; branches of the anterior vagal trunk to the anterior surface of the stomach. Synonym: rami gastrici anteriores nervi vagi. (05 Mar 2000) |
| gastric branches of posterior vagal trunk | Posterior gastric branches; branches of the posterior vagal trunk to the posterior surface of the stomach. Synonym: rami gastrici posteriores nervi vagi. (05 Mar 2000) |
| gastric bypass | Surgical procedure in which the stomach is transected high on the body. The resulting proximal remnant is joined to a loop of the jejunum in an end-to-side anastomosis. This procedure is used frequently in the treatment of morbid obesity. (12 Dec 1998) |

| gastric canal | Furrow formed temporarily between longitudinal rugae of the gastric mucosa along the lesser curvature during swallowing; observed radiographically and endoscopically, it is formed because of the firm attachment of the gastric mucosa to the muscular layer, which is devoid of an oblique layer at this site; said to form a passageway favoured by saliva and small quantities of masticated food and other fluids as they flow from cardia to gastroduodenal junction. Synonym: canalis gastricus, canalis gastrici, magenstrasse. (05 Mar 2000) |
| gastric cancer | Cancer of the stomach, the major organ that holds food for digestion. Stomach cancer (gastric cancer) can develop in any part of the stomach and spread to other organs. Stomach ulcers do not appear to increase a person's risk of developing stomach cancer. Symptoms of stomach cancer are often vague, such as loss of appetite and weight. The cancer is diagnosed with a biopsy of stomach tissue during a procedure. Called an endoscopy. (12 Dec 1998) |
| gastric carcinoma | <radiology> 3rd most common GI malignancy (after colorectal and pancreas), 95% adenocarcinoma (rarely squamous cell or adenoacanthoma), predisposing factors: pernicious anaemia (2X risk), chronic atrophic gastritis, adenomatous and villous polyp (7-27% are malignant), gastrojejunostomy types: polypoid / fungating, ulcerating / penetrating (70%), infiltrating / scirrous = linitis plastica, increase in fibrous tissue; aperistalsis; rigidity, superficial spreading carcinoma, confined to mucosa/submucosa; 95% 5-year survival, patch of nodularity; little loss of elasticity location: 60% lesser curvature, 30% GE junction, 10% greater curvature probability of malignancy of an ulcer: fundus 90%, greater curvature 70%, lesser curvature 10-15% (12 Dec 1998) |
| gastric cardia | The area of the stomach close to the oesophageal opening (cardiac orifice or cardia) which contains the cardiac glands. Synonym: pars cardiaca gastris, pars cardiaca ventriculi, cardia, gastric cardia. (05 Mar 2000) |
