【摘要】：目的通過比較分析放大胃鏡和普通胃鏡下胃癌及癌前病變的胃黏膜病變的形態(tài)特征,評價放大胃鏡對胃黏膜隆起病變定性診斷的臨床價值。方法將2014年3月-2015年3月符合要求的291例患者分成兩組。其中,148例行放大胃鏡檢查,觀察胃小凹及微血管形態(tài),指導(dǎo)靶向活檢;143例行普通胃鏡下的常規(guī)黏膜活檢。結(jié)果放大胃鏡組檢出胃黏膜上皮內(nèi)瘤變25例(16.9%),其中高級別瘤變1例(0.7%),早期胃癌5例,早期胃癌檢出率3.4%,總的胃癌及癌前病變的檢出率20.3%;與普通胃鏡組比較差異具有統(tǒng)計學(xué)意義(P0.05);癌變胃小凹分型為Ⅲ、Ⅳ、Ⅴ型;微血管形態(tài)主要為C型和D型。結(jié)論放大胃鏡有助于發(fā)現(xiàn)早期胃癌及癌前病變。
[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，
