Detection and Diagnosis of Early Gastric Cancer【電子版】

Having already gained some experience in endoscopy before I joined the Cancer Institute Hospital of JFCR, I was under the misapprehension that upper GI endoscopy was easy. At the Cancer Institute Hospital of JFCR, however, I saw lesions I had never seen before-such as gastritis-resembling cancer, minute gastric cancer, and 0-IIb lesions-being detected one after the other. I was astonished by the difference between my competence and that of the doctors at the Institute. When I asked one of them what the secret to finding gastric cancer was, he said that the lesion looked luminous. At first, I didn’t understand what he meant. But once I had looked at enough lesions to get used to them, lesions started jumping out at me. And I understood it was what he meant when he said the lesion looked luminous. (from "Afterword")
