【摘要】：目的评价虚拟色素内镜在小肠黏膜病损成像中的应用价值。方法采用单中心回顾性研究方法,将白光胶囊内镜获取的49例100处小肠病损图像,由两位内镜专家分别在FIC E1、FIC E2、FIC E3及BF 4种条件下重建病损图像,并与白光胶囊内镜获取图像进行比较。K appa系数评价两位专家判别结果的一致性。100处小肠病损包括39处血管病损、49处溃疡(糜烂)病损及12例处水肿(萎缩)病损。结果采用FIC E1、FIC E2、FIC E3和BF图像重建条件后,小肠黏膜病损图像质量提高率分别为77%(77/100)、74%(74/100)、41%(41/100)和39%(39/100),两位专家之间评价一致性程度分别为89%[k=0.833(P0.001),95%C I:0.741~0.925]、85%[k=0.764(P0.001),95%C I:0.654~0.874]、66%[k=0.486(P0.001),95%C I:0.345~0.627]及79%[k=0.593(P0.001),95%C I:0.438~0.748]。结论在常规SBC E-W L对小肠病损成像与表征不直观情况下,可使用虚拟色素内镜检查(尤其是FIC E1),可将虚拟色素内镜检查作为常规白光SBC E检查的补充,用以评估难以解读的内镜图像。
[Abstract]:Objective to evaluate the value of virtual pigment endoscopy in the imaging of intestinal mucosal lesions. Methods the images of 100 small bowel lesions in 49 cases of 100 cases obtained from Baiguang capsule endoscopy were reconstructed by two endoscope experts under four conditions of FIC E1FIC E2FIC E3 and BF, respectively. In comparison with the image obtained from the endoscopy of Baiguang capsule, the .K appa coefficient was used to evaluate the consistency of the two experts' discriminant results. There were 39 vascular lesions, 49 ulcers (erosion) and 12 edema (atrophy) lesions. 缁撴灉閲囩敤FIC E1,FIC E2,FIC E3鍜孊F鍥惧儚閲嶅缓鏉′欢鍚，
