 Many flat esophageal superficial cancers have been detected since the 1980s by chromoendoscopy using iodine solution, and surgical resection has made it possible to obtain definite cure of cancer. However, risks of complication and the appearance of organ dropout symptoms are inevitable, and from the clinicopathological viewpoint, a cure obtained by excessive invasion is a problem. For this reason, various techniques were devised to perform endoscopic resection safely and easily in the esophagus, and esophageal EMR became popular. Furthermore, the expectation for expansion of adaptation of endoscopic resection has increased as the esophageal ESD procedure was established. In addition, it is recognized that precise diagnosis of depth of tumor invasion is indispensable for EMR/ESD adaptation judgment, so ultrasonic diagnosis by high-frequency thin probe and magnified image enhanced endoscopy have been actively used for diagnosis of depth of tumor invasion. With regard to extended indication of endoscopic resection, ESD has largely solved the technical constraints, but there is still a big barrier to metastasis diagnosis. In addition to the hardware development, a breakthrough from the viewpoint of software in how to combine established technologies is ongoing.
