查阅近期国内外文献,各国纤维胃镜(下称胃镜)对早期胃癌的检出率差异很大,日本称冠(有者高达50%),我国却徘徊在5%左右。究其原因,不少诊出的进行期病例,是前不久胃镜未查出病变者,说明操作胃镜尚缺乏经验,对早期恶性病变形态缺乏认识。本文拟就早期胃癌和微小胃癌的胃镜肉眼观察的形态描述,如何与一些胃内良性小病变的区分,胃溃疡与溃疡恶变或溃疡型癌的镜下认识,以及癌前期病变有无可能恶变的镜下形态改变等进行分析。一、如何及时、正确的诊断早期胃癌1962年4月日本的田坂定孝氏提出了早期胃癌的
Looking at the recent domestic and foreign literature, the detection rate of gastric cancer in various countries is very different from that of the gastroscope (hereinafter referred to as gastroscope). Japan is known as the crown (some as high as 50%), but our country suffers from 5% or so. The reason for this is that many of the consultation cases are short-lived gastroscopes that have not been diagnosed, indicating that surgical gastroscopy is still inexperienced and lacks knowledge of the morphology of early malignant lesions. This article intends to describe the morphological description of the gastroscope for early gastric cancer and small gastric cancer, how to distinguish it from some small benign lesions in the stomach, the microscopic understanding of gastric ulcer and ulcer malignant transformation or ulcer cancer, and whether the precancerous lesions may be malignant. Microscopic changes in morphology were analyzed. First, how to promptly and correctly diagnose early gastric cancer in April 1962, Japan’s Tajima Tatsushi proposed early gastric cancer
