| Rehfuss stomach tube | A tube with a calibrated syringe, formerly used for aspiration of stomach contents in gastric analysis; replaced by plastic disposable stomach tube's. (05 Mar 2000) |

| Reichel-Polya stomach resection | Retrocolic anastomosis of the full circumference of the open stomach to the jejunum. (05 Mar 2000) |
| pavlov stomach | A Pavlov pouch fashionned surgically from part of the stomach (which is isolated from the rest of the stomach). The pouch opens through a fistula (canal) on to the abdominal wall and permits sampling of the gastric contents. See pavlov pouch. (12 Dec 1998) |
| chief cell of stomach | <pathology> Cells of the basal part of the gastric glands of the stomach. They contain extensive rough endoplasmic reticulum and zymogen granules and secrete pepsinogen, the inactive precursor of pepsin and rennin. (18 Nov 1997) |
| greater curvature of stomach | The border of the stomach to which the greater omentum is attached. Synonym: curvatura ventriculi major. (05 Mar 2000) |
| rugae of stomach | Characteristic folds of the gastric mucosa, especially evident when the stomach is contracted. Synonym: plicae gastricae, gastric folds, ruga gastrica. (05 Mar 2000) |
| miniature stomach | at different points along the dogs' digestive tracts, the russian physiologist ivan petrovich pavlov (1848-1936) surgically created pockets ( pavlov pouches ) from which he could obtain secretions, the aim being to study the physiology of the digestive tract. He did so from the salivary glands down to the stomach, liver and pancreas with considerable success and in 1904 (the 4th year it was awarded) he received the nobel prise for his work on the physiology of digestion, through which knowledge on vital aspects of the subject has been transformed and enlarged. (12 Dec 1998) |
| pit of stomach | The slight depression in the midline just inferior to the xiphoid process of the sternum. Synonym: fossa epigastrica, pit of stomach, scrobiculus cordis. (05 Mar 2000) |
| muscular coat of stomach | Muscular tunic of the stomach, consisting of smooth muscles arranged in three fairly well defined layers: an outer longitudinal layer, continuous with that of the oesophagus but dividing at the cardia into two bands which run along the greater and lesser curvatures, leaving the middle areas of the anterior and posterior walls devoid of longitudinal fibres, and then coalescing in the pyloric region into a complete layer which is continuous with the longitudinal coat of the duodenum. The middle circular layer is most complete and strongest, continuous with the circular layer of the oesophagus at the cardia; it thickens progressively toward the pylorus, ultimately forming the muscular ring of the pyloric sphincter. The inner, oblique layer is unique to the stomach and is most strongly developed in the fundic region and absent along the lesser curvature. This absence contributes to the formation of the "gastric canal." See: oblique fibres of stomach. Synonym: tunica muscularis gastrica, tunica muscularis ventriculi. (05 Mar 2000) |
| posterior wall of stomach | That part of the gastric wall that faces the omental bursa. Synonym: paries posterior gastris. (05 Mar 2000) |
| powdered stomach | The dried and powdered defatted wall of the stomach of the hog, Sus scrofa; it contains thermolabile factors including native vitamin B12 and intrinsic factor; has been used in the treatment of pernicious anaemia. (05 Mar 2000) |
| sclerotic stomach | leather-bottle stomach |
| hourglass stomach | A condition in which there is a central constriction of the wall of the stomach dividing it into two cavities, cardiac and pyloric. Synonym: bilocular stomach, ectasia ventriculi paradoxa. Leather-bottle stomach, marked thickening and rigidity of the stomach wall, with reduced capacity of the lumen although often without obstruction; nearly always due to scirrhous carcinoma, as in linitis plastica. Synonym: sclerotic stomach. (05 Mar 2000) |
| serosa of stomach | Serous coat of the stomach; the visceral peritoneum covering the outer surface of the stomach. Synonym: tunica serosa gastrica, tunica serosa ventriculi. (05 Mar 2000) |
| small bowel disease involving stomach | <radiology> Lymphoma, eosinophilic gastroenteritis, Zollinger-Ellison syndrome (12 Dec 1998) |
