Carcinomas of the esophagus have a higher degree of malignancy than gastric carcinomas. Likewise, the therapeutic response of esophageal cancer patients to radical surgery has been poor because a thoracotomy and/or laparotomy are required. Since the advent of the iodine staining technique for the detection of esophageal carcinoma, the diagnosis of small, thin lesions limited to the mucosa ha become endoscopically possible. Progress in diagnostic techniques has thus resulted in the detection of increasing numbers of early carcinomas. Recent advances in techniques for the endoscopic mucosectomy of early esophageal carcinomas have similarly contributed to an increasing trend towards early detection and endoscopic resection. As mucosectomy is indicated for the treatment of small, thin lesions without lymh node metastases, a new endoscopic classification system has become necessay, to insure improved diagnostic accuracy.
