This radiography shows the result of a corrosive injury which is stricture formation
This occur due to acids or alkalies. Alkalies are odourless and tasteless so they are more likely to be ingested. The effects of alkalies are liquefaction, dehydration, and thrombosis of blood vessels and they usually lead to fibrous scarring. While Acids can cause coagulative necrosis with eschar formation. The best way to diagnose these conditions is by skilled early endoscope, deep ulcers and lesions will most likely perforate the wall of esophagus, but if there is only edema of the mucosa then eventually it will heal. The most important complication which is seen in this photography is stricture formation and it requires regular endoscopy to be assessed. Note that corresives such as sodium hydroxide or sulphuric acid are used for suiciding purpose, and accidental ingestion might be seen in children.
