n a narrowing or restriction of the lumen of the esophagus that slows or impedes the passage of fluid and foods from the oral cavity to the stomach.

stenosis

narrowing or contraction of a body passage or opening. See also specific anatomical sites.

aortic stenosis
obstruction to the outflow of blood from the left ventricle into the aorta. May be due to an anomaly of the valves (valvular), an obstruction in the ascending aorta (supravalvular), or an obstruction in the left ventricular outflow tract (subvalvular). See also aortic subvalvular stenosis, aortic valvular disease.
esophageal stenosis
a common cause of esophageal obstruction, caused commonly by esophageal trauma; congenital stenosis often associated with tracheoesophageal fistula.
left atrioventricular stenosis
see mitral stenosis (below), valvular stenosis.
mesonephric duct stenosis
occurs as stenosis of the ductus deferens or epididymis; may be associated with renal aplasia.
mitral stenosis
a narrowing of the left atrioventricular orifice. See also mitral commissurotomy.
nasopharyngeal stenosis
an acquired disorder in cats, usually following chronic upper respiratory infection, which causes upper airway obstruction with mucopurulent nasal discharge and a wheezing respiration, which is relieved with open mouth breathing.
paramesonephric duct stenosis
focal defects in the duct lead to segmental aplasia or stenosis of the uterine tube or horn.
pulmonary artery stenosis
the commonest cardiac defect in dogs; it is a narrowing of the pulmonary outflow tract and may occur in any one of a number of common sites including infundibular, valvular and subvalvular.
rectovaginal stenosis
see rectovaginal constriction.
right atrioventricular stenosis
see tricuspid stenosis (below).
subepiglottic stenosis
has the effect of reducing air flow into and out of the lungs.
tricuspid stenosis
narrowing or stricture of the tricuspid orifice of the heart.

Although peptic strictures are common, progression to complete esophageal stenosis in the upper esophagus occurs rarely.
5) In our elderly patient, additional factors besides GERD--such as the use of medications that may decrease lower esophageal sphincter pressure, disturbance in esophageal motility from aging, and absence of the typical symptoms of heartburn that delayed adequate diagnosis--likely contributed to esophageal stenosis.
