目的:探讨窄带成像(NBI)技术在喉部肿瘤中的应用。方法:选取2014-04-2016-10期间就诊于我院门诊,怀疑喉部恶性肿瘤或癌前病变的312例患者,每位患者均用白光和NBI模式的电子鼻咽喉镜进行观察,以病理结果为诊断金标准,判断白光模式和NBI模式电子鼻咽镜对喉部肿瘤诊断的敏感性、特异性和准确性。结果:白光模式对喉肿物诊断的敏感性、特异性和准确性分别为77.17%、62.07%和74.36%;NBI模式对喉肿物诊断的敏感性、特异性和准确性分别为92.91%、77.59%和90.06%;NBI模式对喉肿物诊断的敏感性和准确性均高于白光模式,差异有统计学意义(P<0.05,),但两者对喉肿物诊断的特异性差异无统计学意义(P>0.05)。结论:电子鼻咽喉镜NBI技术不仅发现喉癌早期病变,而且可以提高喉部肿瘤诊断的敏感性和准确性,有着广阔的应用前景。
Objective: To investigate the application of narrow-band imaging (NBI) technique in laryngeal neoplasms. Methods: A total of 312 patients with out-patient in our hospital, suspected of laryngeal malignancy or precancerous lesions were enrolled during the period of 2014-04-2016-10. Each patient was observed by electronic nasopharyngoscope with white light and NBI mode. Results for the gold standard of diagnosis, to determine the white light mode and NBI mode electronic nasopharyngeal laryngeal cancer diagnosis of tumor sensitivity, specificity and accuracy. Results: The sensitivity, specificity and accuracy of the white model for the diagnosis of laryngeal tumor were 77.17%, 62.07% and 74.36% respectively. The sensitivity, specificity and accuracy of NBI for the diagnosis of laryngeal tumor were 92.91% 77.59% and 90.06%, respectively. The sensitivity and accuracy of NBI for the diagnosis of laryngeal tumor were higher than those of white light (P <0.05, P <0.05), but there was no difference between the two methods in the diagnosis of laryngeal tumor Statistical significance (P> 0.05). Conclusion: The electronic rhinolaryngoscope NBI technique not only detects early lesions of laryngeal cancer, but also can improve the sensitivity and accuracy of laryngeal cancer diagnosis and has broad application prospects.
