【摘要】：目的通过比较分析放大胃镜和普通胃镜下胃癌及癌前病变的胃黏膜病变的形态特征,评价放大胃镜对胃黏膜隆起病变定性诊断的临床价值。方法将2014年3月-2015年3月符合要求的291例患者分成两组。其中,148例行放大胃镜检查,观察胃小凹及微血管形态,指导靶向活检;143例行普通胃镜下的常规黏膜活检。结果放大胃镜组检出胃黏膜上皮内瘤变25例(16.9%),其中高级别瘤变1例(0.7%),早期胃癌5例,早期胃癌检出率3.4%,总的胃癌及癌前病变的检出率20.3%;与普通胃镜组比较差异具有统计学意义(P0.05);癌变胃小凹分型为Ⅲ、Ⅳ、Ⅴ型;微血管形态主要为C型和D型。结论放大胃镜有助于发现早期胃癌及癌前病变。
[Abstract]:Objective to evaluate the clinical value of magnifying gastroscopy in the qualitative diagnosis of gastric mucosal eminence by comparing and analyzing the morphologic features of gastric cancer and precancerous lesions under magnifying gastroscope and general gastroscopy. Methods 291 patients who met the requirements from March 2014 to March 2015 were divided into two groups. One hundred and forty-eight cases were examined by magnifying gastroscopy, and the morphology of gastric fovea and microvessel were observed, and 143 cases of routine mucosal biopsy under general gastroscope were guided by targeted biopsy. Results 25 cases (16.9%) of gastric mucosal intraepithelial neoplasia were detected in magnified gastroscopy group, including 1 case (0.7%) of high grade neoplasia and 5 cases of early gastric cancer. The detection rate of early gastric cancer was 3.4. The detection rate of total gastric cancer and precancerous lesions was 20.3.The difference was statistically significant compared with the common gastroscopy group (P0.05); the type 鈪，
