Value of narrow-band imaging technique combined with staining magnifying endoscopy in the diagnosis of early colorectal cancer

目的探讨窄带成像技术(NBI)联合染色放大内镜诊断早期大肠癌的价值观察。方法选取2018年4月~2019年9月于我院内镜中心行内镜检查发现有结肠肿瘤样病变的患者67例入组,对入组患者的86枚肿瘤样病变行NBI+染色放大内镜观察腺管及血管分布情况,记录诊断结果;同时行活组织病理检查,比较NBI+染色放大内镜检查结果与病理结果,分析两组数据的一致性。结果NBI联合染色放大内镜诊断早期大肠癌的灵敏度、特异度、检出正确率、阳性预测值和阴性预测值分别为94.44%、90.32%、92.54%、91.89%和93.33%,两种诊断结果Kappa值为0.850。结论采用NBI联合染色放大内镜诊断结肠肿瘤样病变与活组织学病理检查诊断结果具有一致性,对早期大肠癌病变的诊断具有临床应用价值。

Objective To investigate the value of narrow-band imaging(NBI)combined with staining magnifying endoscopy in the diagnosis of early colorectal cancer.Methods Sixty-seven patients with colonic tumor-like lesions under undoscopy examination were enrolled in the endoscopy center of our hospital from April 2018 to September 2019.Glandular and vascular distributions of 86 tumor-like lesions in enrolled patients were observed by NBI+staining magnifying endoscopy.The diagnostic results were recorded.At the same time,biopsy pathology was performed.The results between NBI+staining magnifying endoscopy and pathological results were compared.The consistency of the two groups was analyzed.Results The sensitivity,specificity,detection accuracy,positive predictive value and negative predictive value of NBI combined with staining magnifying endoscopy in the diagnosis of early colorectal cancer were 94.44%,90.32%,92.54%,91.89%and 93.33%,respectively.The kappa value of two diagnostic results was 0.850.Conclusion The use of NBI combined with staining magnifying endoscopy to diagnose colonic tumor-like lesions is consistent with biopsy pathological findings.It has clinical value for the diagnosis of early colorectal cancer lesions.
