The problems of corrosive esophagitis and esophageal stricture are still prevelant, although recently their incidence has markedly decreased. A clinical and statistical analysis was made for the 141 cases of corrosive esophagitis and esophageal stricture who were admitted to the Seoul National University Hospital during 1962-1968. The total number of patients who visited the OPD decreased from 75 per year during the 1945-1949 period to 42 per year during the period from 1962-1968. The cases due to lye ingestion decreased from 93.75% to 73.10% but the cases due to acetic acid ingestion increased from 2.22% to 18.4%. Those patients under the age of five included 25.50% of the total cases seen. Of thses children under five, 80% of this group was male. While in the adult group female outnumbered the males by 71.20%. In comparison with the reports from Europe and America, the adult percentage and lye ingestion percentage are much higher in this study. The treatment used for corrosive esophagitis was based upon early bougination with Nelaton's urethral catheter and administration of cortisone and antibiotics. Out of 73 patients receiving therapy 8 cases developed esophageal stricture and 4 cases died during treatment. Out of 68 cases of esophageal stricture 45.6% received a successful dilatation while 20.6% of the cases resulted in permanent gastrostomy or dilatation failure.
