ME-NBI在早期胃癌中的应用

目的分析放大内镜结合窄带成像(ME-NBI)技术在早期胃癌筛查中应用价值。方法选择早期胃癌高危风险患者96例,无论是门诊还是住院患者需接受消化内镜检查并诊断明确,白光镜(WLE)观察,识别胃腔病灶,再行ME-NBI检查,局部取样做病理检查。结果8例患者在WLE下即发现有恶性肿瘤病灶,分别为胃上皮内瘤变及早期胃癌。16例患者在ME-NBI模式下于胃中发现上述病变。两种检查准确率比较,ME-NBI(81.25%)比WLE(58.33%)更高(P<0.05)。结论在早期胃癌检测方面ME-NBI优势更为明显,其检测结果与病理结果较符合。

Objective To analyze the application value of magnifying endoscopy combined with narrow-band imaging(ME-NBI)in early gastric cancer screening.Methods Patients at high risk of early gastric cancer were selected as the research object.Both outpatients and inpatients needed to undergo digestive endoscopy and the diagnosis was confirmed.A total of 96 patients were enrolled.Results Eight patients were found to have malignant tumors under white light microscope,including gastric intraepithelial neoplasia and early gastric cancer.These lesions were found in the stomach in the ME-NBI mode in 16 patients.The accuracy of the two tests was compared,indicating that the ME-NBI(81.25%)was higher than the WLE(58.33%)for the above malignant lesions,with statistical significance(all P<0.05).Conclusion ME-NBI has more obvious advantages in the detection of early gastric cancer,and its detection results are consistent with pathological results.
