Magnifying endoscopy with narrow-band imaging is helpful in the differential diagnosis between low-grade adenoma and early cancer of superficial elevated gastric lesions

目的研究放大内镜结合窄带成像(M-NBI)对胃浅表隆起性低级别腺瘤与早期胃癌的诊断价值。方法选取2016-09~2018-05于郑州大学第二附属医院行无痛胃镜检查的53例胃浅表隆起性病变的患者,分别采用白光成像(C-WLI)和M-NBI对同一患者进行诊断,分析和比较两种方法的灵敏度、特异度和准确度。结果C-WLI的诊断灵敏度、特异度和准确度分别为64.0%、90.0%、72.0%;M-NBI的诊断灵敏度、特异度和准确度分别为94.0%、90.0%和93.0%。结论M-NBI有助于鉴别浅表隆起性胃癌和腺瘤。

Objective To study the diagnostic value of magnifying endoscopy and narrow-band imaging(M-NBI)in diagnosis of low grade adenoma and early carcinoma of gastric superficial elevated gastric lesions.Methods From September 2016 to May 2018,53 cases of superficial protuberance lesions of stomach were examined by painless gastroscopy in the Second Affiliated Hospital of Zhengzhou University,who were selected into this study.Diagnostic tests were performed on a patient using white light imaging(C-WLI)and M-NBI,and we determined the sensitivity,specificity and accuracy of C-WLI and M-NBI.Results The sensitivity,specificity and accuracy of C-WLI were 64.0%,90.0%and 72.0%,respectively.The sensitivity,specificity and accuracy of M-NBI were 94.0%,90.0%and 93.0%,respectively.Conclusion M-NBI is helpful in differentiating cancerous superficial elevated lesions of the stomach from adenoma.
