目的探讨利用窄带成像(NBI)联合放大内镜技术观察大肠息肉表面毛细血管形态对大肠息肉病理性质的诊断价值。方法选取我院2014-01-01-2014-03-31行大肠内镜检查患者652例,应用NBI放大内镜观察大肠息肉表面的微血管形态,根据Showa的分型方法对大肠息肉的肿瘤性及非肿瘤性病理类型进行预测,并与病理结果进行对照,判定其病理符合率、敏感性及特异性。结果有102例患者发现大肠息肉,共131枚,普通白光内镜对于大肠肿瘤性病变的病理符合率71.76%,敏感性56.82%,特异性79.31%;窄带成像联合放大内镜应用此CP分型法对于大肠肿瘤性病变的病理符合率为90.08%,敏感性为87.50%,特异性为91.21%,明显优于普通内镜,两种情况下总病理符合率差异有统计学意义,P<0.05。结论 NBI放大内镜观察大肠息肉表面微血管形态对于鉴别肿瘤性病变与非肿瘤性病变,内镜与病理有较高的符合率。
Objective To explore the diagnostic value of narrow-band imaging (NBI) combined with magnifying endoscopy on the pathological features of colorectal polyps by observing the capillary morphology of colorectal polyps. Methods 652 cases of colorectal endoscopy were selected in our hospital from January 2014 to January 2014, and the microvascular morphology on the surface of colorectal polyps was observed with NBI magnifying endoscopy. According to Showa’s classification method, Non-neoplastic pathological types were predicted and compared with the pathological results to determine the pathological compliance rate, sensitivity and specificity. Results A total of 131 colorectal polyps were found in 102 patients. The pathological coincidence rate of common white light endoscopy for colorectal neoplasia was 71.76%, the sensitivity was 56.82% and the specificity was 79.31%. The narrow band imaging combined with magnifying endoscopy was applied to this CP type The coincidence rate was 90.08%, the sensitivity was 87.50% and the specificity was 91.21%, which was significantly better than that of the ordinary endoscope. The total pathological coincidence rate of the two methods was statistically significant (P <0.05) . Conclusion NBI enlarged endoscopic observation of colorectal polyp surface microvascular morphology for the identification of neoplastic and non-neoplastic lesions, endoscopy and pathology have a higher coincidence rate.
