Abstract
The incidence of carcinoma of the esophagus among patients with chronic esophageal stricture caused by ingestion of corrosive agents is reported to be significantly higher than that of the general population. The question of whether or not a resection of the diseased esophagus should be included in the surgical reconstruction procedure of the undilatable esophageal stricture continues to be a controversial. During the 12 year period from 1988 to 1999, a total of 54 consecutive patients with caustic stricture of the esophagus were treated in our department. We retrospectively reviewed these cases and analyzed the incidence of cicatrical carcinoma among the patients and the risk of esophagectomy according to the procedures performed. We found seven cases of esophageal cancer among these patients. There was no significant increase in mortality or morbidity related to esophagectomy. Considering the high incidence of cicatrical carcinoma from the stricture sites as well as the possible chance of hidden malignancy, we concluded that the simultaneous resection of the esophagus with reconstruction for patients with chronic intractable caustic stricture would give the patients a better probability of being completely cured of the disease.
