Twenty six cases of corrosive esophagitis were studied clinically during the period of 1982 through 1988. The results obtained were as follows : 1) Acid corrosive agents were more common than alkaline agent. The most common corrosive agent was glacial acetic acid(46.2%). 2) Early esophagoscopy was performed in 18 cases in order to determine the extent of esophageal burns and to make a guidline of treatments. 3) Nasogastric tube was inserted for nutritional supply and maintenance of esophageal lumen. 4) Various treatments were done such as antibiotics, steroid, nasogastric tube, esophageal dilation and esophageal reconstruction. 5) Serious complications were esophageal stricture(7), esophageal perforation associated with empyema and sepsis(1), hypopharyngeal stenosis(1), nasopharyngeal stenosis(1) and 1 case was expired during treatment. 6) Among 26 cases of esophageal burn, 20 cases had favorable treatment result but 6 cases still have had esophageal stricture, failure of esophageal reconstruction, hypopharyngeal stricture and nasopharyngeal stricture.
