Gastric Antral Vascular Ectasia
|
D020252 |
[A distinct vascular lesion in the PYLORIC ANTRUM that is characterized by tortuous dilated blood vessels (ectasia) radiating outward from the PYLORUS. The vessel pattern resembles the stripes on the surface of a watermelon. This lesion causes both acute and chronic GASTROINTESTINAL HEMORRHAGE.

Gastric Artery

|
Gastric Balloon
|
D015905 |
[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.

|
Gastric Bypass
|
D015390 |
[Surgical procedure in which the STOMACH is transected high on the body. The resulting small proximal gastric pouch is joined to any parts of the SMALL INTESTINE by an end-to-side SURGICAL ANASTOMOSIS, depending on the amounts of intestinal surface being bypasses. This procedure is used frequently in the treatment of MORBID OBESITY by limiting the size of functional STOMACH, food intake, and food absorption.
, A small proximal gastric pouch is created by double stapling that excludes the distal STOMACH. The pouch is connected to the JEJUNUM using a roux-en-Y gastrojejunal anastomosis.

|
Gastric Dilatation
|
D013271 |
[Abnormal distention of the STOMACH due to accumulation of gastric contents that may reach 10 to 15 liters. Gastric dilatation may be the result of GASTRIC OUTLET OBSTRUCTION; ILEUS; GASTROPARESIS; or denervation.
] |
|
Gastric Emptying
|
D005746 |
[The evacuation of food from the stomach into the duodenum.
] |
|
Gastric Fistula
|
D005747 |
[Abnormal passage communicating with the STOMACH.
] |
|
Gastric Fundus
|
D005748 |
[The superior portion of the body of the stomach above the level of the cardiac notch.
] |
|
Gastric Hypothermia
|
D050786 |
[A method of lowering core BODY TEMPERATURE by filling the STOMACH with chilled fluids.
] |
|
Gastric Inhibitory Polypeptide
|
D005749 |
[A gastrointestinal peptide hormone of about 43-amino acids. It is found to be a potent stimulator of INSULIN secretion and a relatively poor inhibitor of GASTRIC ACID secretion.
] |
|
Gastric Juice
|
D005750 |
[The liquid secretion of the stomach mucosa consisting of hydrochloric acid (GASTRIC ACID); PEPSINOGENS; INTRINSIC FACTOR; GASTRIN; MUCUS; and the bicarbonate ion (BICARBONATES). (From Best & Taylor's Physiological Basis of Medical Practice, 12th ed, p651)
] |
|
Gastric Lavage
|
D005751 |
[Medical procedure involving the emptying of contents in the stomach through the use of a tube inserted through the nose or mouth. It is performed to remove poisons or relieve pressure due to intestinal blockages or during surgery.
] |
|
Gastric Mucins
|
D005752 |
[Mucins that are found on the surface of the gastric epithelium. They play a role in protecting the epithelial layer from mechanical and chemical damage.
] |
|
Gastric Mucosa
|
D005753 |
[Lining of the STOMACH, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. The surface cells produce MUCUS that protects the stomach from attack by digestive acid and enzymes. When the epithelium invaginates into the LAMINA PROPRIA at various region of the stomach (CARDIA; GASTRIC FUNDUS; and PYLORUS), different tubular gastric glands are formed. These glands consist of cells that secrete mucus, enzymes, HYDROCHLORIC ACID, or hormones.
] |
|
Gastric Outlet Obstruction
|
D017219 |
[The hindering of output from the STOMACH into the SMALL INTESTINE. This obstruction may be of mechanical or functional origin such as EDEMA from PEPTIC ULCER; NEOPLASMS; FOREIGN BODIES; or AGING.
] |
|
Gastric Stump
|
D018530 |
[That portion of the stomach remaining after gastric surgery, usually gastrectomy or gastroenterostomy for cancer of the stomach or peptic ulcer. It is a common site of cancer referred to as stump cancer or carcinoma of the gastric stump.
] |
|
Gastrin-Releasing Peptide
|
D019886 |
[Neuropeptide and gut hormone that helps regulate GASTRIC ACID secretion and motor function. Once released from nerves in the antrum of the STOMACH, the neuropeptide stimulates release of GASTRIN from the GASTRIN-SECRETING CELLS.
] |
|
Gastrin-Secreting Cells
|
D019863 |
[Endocrine cells which secrete GASTRIN, a peptide that induces GASTRIC ACID secretion. They are found predominantly in the GASTRIC GLANDS of PYLORIC ANTRUM in the STOMACH, but can also be found in the DUODENUM, nervous and other tissues.
] |
|
Gastrinoma
|
D015408 |
[A GASTRIN-secreting neuroendocrine tumor of the non-beta ISLET CELLS, the GASTRIN-SECRETING CELLS. This type of tumor is primarily located in the PANCREAS or the DUODENUM. Majority of gastrinomas are malignant. They metastasize to the LIVER; LYMPH NODES; and BONE but rarely elsewhere. The presence of gastrinoma is one of three requirements to be met for identification of ZOLLINGER-ELLISON SYNDROME, which sometimes occurs in families with MULTIPLE ENDOCRINE NEOPLASIA TYPE 1; (MEN 1).
