| gastric mucosa | Surface epithelium in the stomach that invaginates into the lamina propria, forming gastric pits. Tubular glands, characteristic of each region of the stomach (cardiac, gastric, and pyloric), empty into the gastric pits. The gastric mucosa is made up of several different kinds of cells.

| gastric narrowing | <radiology> Neoplastic, carcinoma (linitis plastica), lymphoma, metastases, inflammatory, caustic, radiotherapy, granulomatous disease: Crohn disease, TB, sarcoidosis, eosinophilic enteritis see: gastric outlet obstruction (12 Dec 1998) |
| gastric neurasthenia | A condition marked by vague epigastric atony and distention, and mild neurasthenic symptoms. (05 Mar 2000) |
| gastric outlet obstruction | <paediatrics, surgery> A congenital disorder in which the pylorus is thickened causing obstruction of the gastric outlet (to the duodenum). More common in males, pyloric stenosis. Symptoms of projectile vomiting begin several weeks after birth. Incidence: approximately 1 in 4,000 live births. (27 Sep 1997) |
| gastric pit | One of the numerous small pits in the mucous membrane of the stomach that are the mouths of the gastric glands. Synonym: foveola gastrica. (05 Mar 2000) |

| gastric smear | A group of cytologic specimens containing material from the mouth (oral smear), oesophagus and stomach (gastric smear), duodenum (paraduodenal smear), and colon, obtained by specialised lavage techniques; used principally for the diagnosis of cancer of those areas. (05 Mar 2000) |

| gastric ulcer | <gastroenterology> An ulcer in the mucosal lining of the stomach. Ulcer formation results from gastric inflammation that may be triggered by the use of alcohol, aspirin or non-steroidal anti-inflammatories agents. Symptoms include recurrent abdominal pains (may be relieved by antacids), nausea, vomiting, weight loss and fatigue. Complications include GI bleeding, obstruction, perforation and ulcer penetration into surrounding tissues. Treatment includes the avoidance of alcohol, smoking, aspirin, anti-inflammatories and caffeine. Medications such as antacids or H2 antagonists (for example cimetidine, ranitidine) or proton pump inhibitors (omeprazole) have been shown to be effective treatment. (27 Sep 1997) |
| gastric ulcers | <radiology> Criteria for benignity: projection beyond luminal contour, depth greater than width, smooth fading of gastric folds, lesser curvature (not reliable), concomitant duodenal ulcers, Hampden's line (1-mm lucent line), persistent pooling of barium in crater see also: Carman meniscus sign (12 Dec 1998) |
| gastric varices | <radiology> Usually associated with oesophageal varices (due to portal hypertension), if WITHOUT oesophageal varices most likely to be consider splenic vein thrombosis due to: pancreatitis / panc carcinoma, increased clotting tendency (polycythemia, etc.) Differential diagnosis: thick gastric folds (12 Dec 1998) |
