Clinical Information for Other diseases of stomach and duodenum (K31)

Gastroparesis - Chronic delayed gastric emptying. Gastroparesis may be caused by motor dysfunction or paralysis of STOMACH muscles or may be associated with other systemic diseases such as DIABETES MELLITUS.

Achlorhydria - A lack of HYDROCHLORIC ACID in GASTRIC JUICE despite stimulation of gastric secretion.

Gastric Fistula - Abnormal passage communicating with the STOMACH.

Pyloric Stenosis - Narrowing of the pyloric canal with varied etiology. A common form is due to muscle hypertrophy (PYLORIC STENOSIS, HYPERTROPHIC) seen in infants.

Pyloric Stenosis, Hypertrophic - Narrowing of the pyloric canal due to HYPERTROPHY of the surrounding circular muscle. It is usually seen in infants or young children.

Stomach - An organ of digestion situated in the left upper quadrant of the abdomen between the termination of the ESOPHAGUS and the beginning of the DUODENUM.

Hypertrophy - General increase in bulk of a part or organ due to CELL ENLARGEMENT and accumulation of FLUIDS AND SECRETIONS, not due to tumor formation, nor to an increase in the number of cells (HYPERPLASIA).
