Endoscopic examination of corrosive injuries of the upper gastrointestinal tract

The authors present the case histories of five patients who have sustained corrosive injuries of the upper gastrointestinal tract. Flexible endoscopic examination was successfully carried out in each patient to assess the extent of the injury and anticipate further therapeutic needs. Three patients sustained major gastric lesions, i.e., strictures or bleeding following the ingestion of alkali, acids, or phenol, and one instance of esophageal stricture was recognized. The endoscopic observation of antral gangrene was inexorably followed by antral stricture requiring surgical management. One fatality followed rigid esophagoscopic examination which resulted in esophageal perforation.
