**Abstract**

Corrosive ingestion is an important health problem and medical emergency worldwide. It occurs by accident or by intention. Acids cause coagulation necrosis, and alkalis cause liquefaction necrosis. In the acute period, stabilization of the patient is most important. Airway assessment and prompt management are a priority for severe cases. Caustic substance reflux into the esophagus resulting in further damage should be prevented. The initial evaluation should be performed by endoscopy and graded according to the Zargar classification. Computed tomography (CT) should be used to assess injury to the esophagus because CT is noninvasive. For Zargar 3b injuries, views from both endoscopy and CT scans should be considered. Post-corrosive esophageal stricture is a complication that responds poorly to treatment. Research and development for stricture prevention are ongoing, especially for Zargar 2b and 3a cases.
