目的探讨窄带成像(NBI)结肠镜对结肠息肉样病变的病理组织类型的预测能力.方法 125例患者接受结肠镜检查诊断结肠息肉样病变173个,根据腺管开口形态及NBI下血管分型判定该病变为肿瘤性病变(结肠腺瘤、结肠癌)或非肿瘤性病变,并与病理结果对照,判定各种方法的敏感性、特异性及准确率.结果 NBI下血管形态鉴别肿瘤性或非肿瘤性病变的敏感性、特异性及准确率(94.83%、91.23%、93.64%)以及隐窝形态结合血管形态鉴别肿瘤性或非肿瘤性病变的敏感性、特异性及准确率(95.69%、96.49%、95.59%)显著高于常规内镜(80.17%、84.21%、81.50%)(P<0.05).血管形态鉴别腺瘤与结肠癌的敏感性、特异性、准确率为86.90%、100.00%、87.93%.结论 NBI模式下结肠镜检查对息肉样病变的肿瘤性、非肿瘤性,结肠腺瘤、结肠癌的鉴别优于常规内镜检查,接近病理学检查.

Objective To investigate the value of colonoscopy with narrow band imaging (NBI) in predicting the histology of colorectal polypoid lesions. Methods A total of 173 colorectal polypoid lesions from 125 patients were included in the study. The lesions were diagnosed as neoplastic (adenoma or cancer)or non-neoplastic based on pit patterns and/or capillary patterns (CP), which was compared with the results of pathology, and the sensitivity, specificity and accuracy of each method were evaluated. Results In differentiation between neoplastic and non-neoplastic lesions, the sensitivity, specificity and accuracy of CP (94. 83% , 91. 23% and 93.64% , respectively), and those of CP combined with pit patterns (95. 69% ,96.49% and 95. 59% , respectively) were significantly higher than those of conventional colonoscopy (80. 17% , 84.21% and 81.50% , respectively, P<0.05). In differentiation between adenoma and cancer,the sensitivity, specificity and accuracy of CP were 86.90% , 100.00% and 87.93% , respectively.Conclusion NBI is superior to conventional colonoscopy in differentiation between neoplastic and non-neoplastic lesions, as well as in differentiation between adenoma and carcinoma.
