摘　　要：我国是胃癌高发国家,据不完全统计,其年发病率约35-40/10万,男性高于女性。就世界范围而言,胃癌高发国家集中在东亚国家,其中韩国、日本及我国占全球胃癌发病的60%,其中我国是韩日中的40%以上[1-2]。胃癌占我国全身恶性肿瘤发病率的第3位,病死率约14.33%,农村远高于城市,占第1位[3]。癌组织浸润仅限于黏膜层及黏膜下层者均属早期胃癌（early gastric carcinoma,EGC）。The highest incidence of gastric cancer occurs in the East Asia（China,Korea,and Japan）.The overall prognosis of gastric cancer is dismal.The average 5-year survival rate is less than 20%,and early gastric cancer（EGC） is often clinically silent.However,if the cancer is detected and endoscopically resected prior to invasion into the muscularis propria,the 5-year survival rate can reach 90%.Thus,the early detection of EGC is important.Image enhanced endoscopy（IEE） involves the use of dyes,optical methods（by manipulation of the light source）,and electronic methods（by manipulation of captured light）,to increase the contrast of surface structure,and thus improve visualization and diagnostic accuracy.Endoscopic resection using endoscopic mucosal resection（EMR） technique or endoscopic submucosal dissection（ESD） is potentially curative for the patients without nodal metastasis,and can avoid the morbidity associated with gastrectomy.Thus it is important to strengthen the understanding and increase endoscopic skills of EGC to improve the diagnosis and treatment.
