Surgical treatments were performed in 765 patients of the esophageal diseases at National Medical Center from 1959 to 1982. During these periods, we experienced 945 cases of the esophageal diseases. There were 401 males and 364 females and ranging from 4 days to 76 years of age and mean age was 32.4 years. The most highest mortality noted as 23.0% in esophageal perforation cases. In esophageal strictures cases, the rate of surgical mortality was 5.4%[21/386]. The over all mortality in esophageal surgical cases was 10.8%. We want to expressed about the incidence of Corrosion Carcinoma which developed from the benign esophageal stricture as 2.2%[12/550] of total stricture and as 4.9%[12/241] of total esophageal carcinoma. And the esophagoscopic biopsy must be done who had long standing history of esophageal stricture as a preoperative evaluation purpose.
