Narrowing of the oesophagus that can bring swallowing difficulties, pain, weight loss, and regurgitation of food.
Oesophageal stricture can be caused by cancer of the oesophagus, or due to any various noncancerous causes. These include constant reflux oesphagtitis, in which persistent irritation from gastric acid creates swelling and inflammation followed by the appearance of fibrous scar tissue and narrowing. In Plummer-Vinson syndrome, a web of tissue forms in the upper oesophagus in association with iron deficiency anaemia . A schatzki ring (a non-cancerous fibrous ring found in the lower oesophagus) can also cause problems in swallowing. Overextended use of a nasogastric tube can inflame the oesophagus, causing a stricture, as can consuming a corrosive liquid.
