摘要
目的探讨窄带成像放大内镜和共聚焦激光显微内镜在诊断胃肿瘤性病变中的价值。方法选择2015年1月~2016年12月在我院就诊的疑似胃部恶性病变的患者100例为研究对象。所有患者均行常规白光内镜、窄带成像放大内镜、共聚焦内镜检查。以病理检查结果为金标准,分析窄带成像放大内镜、共聚焦内镜检查敏感度、特异度、阳性预测值、阴性预测值,并分析与病理检查结果的一致性。结果窄带成像放大内镜诊断敏感度91.1%;特异度96.3%;阳性预测值93.2%;阴性预测值92.9%。与病理诊断的一致性分析结果显示κ=0.85。共聚焦内镜诊断敏感度91.1%;特异度90.9%;阳性预测值89.1%;阴性预测值92.6%。与病理诊断的一致性分析结果显示κ=0.82。窄带成像放大内镜与共聚焦内镜在诊断胃肿瘤性病变中的敏感度、特异度、阳性预测值以及阴性预测值比较差异无统计学意义(P>0.05)。结论窄带成像放大内镜和共聚焦激光显微内镜诊断胃肿瘤性病变与病理结果具有较高的一致性。
Objective To discuss the value of narrow band imaging magnifying endoscope and confocal laser scanning microscopy in the diagnosis of gastric lesions. Methods 100 cases with gastric lesions from Jan 2015 to Dec 2016 were selected as subjects. All cases were detected with conventional white light endoscopy, narrow band imaging magnifying endoscope and confocal laser scanning microscopy. The gold standard was based on the pathological examination re- sults, and sensitivity, specificity, positive predictive value, negative predictive value of narrow band imaging magnifying endoscope and confocal laser scanning microscopy were analyzed. Uniformity was analyzed between the results with pathological examination results. Results Narrow band imaging magnifying endoscope： sensitivity was 91.1%, specificity was 96.3%, positive predictive value was 93.2%, negative predictive value was 92.9%, and the results of uniformity was K=0.85. Confocal laser scanning microscopy： sensitivity was 91.1%, specificity was 90.9%, positive predictive value was 89.1%, negative predictive value was 92.6%, and the results of uniformity was K=0.82. The sensitivity, specificity, pos- itive predictive value, negative predictive value of narrow band imaging magnifying endoscope and confocal laser scan- ning microscopy were compared, the differences were no statistically significant （P〉0.05）. Conclusion Narrow band imaging magnifying endoscope and confocal laser scanning microscopy in the diagnosis of gastric lesions are with high consistency with pathological examination results.
