摘要 目的探讨放大内镜结合窄带成像下微血管密度对胃早期肿瘤性病变的诊断价值。方法选择回顾性分析经血管与表面结构分型和微血管密度评估的100例意思胃早期肿瘤性病变者资料。比较单纯经血管与表面结构分型、微血管密度评估及二者联合诊断的准确性。结果 100例患者中肿瘤性病变46例,非肿瘤性病变54例。肿瘤性病变中不规则的黏膜微血管、不规则的表面腺管、分界线、黏膜微血管密度增加案例数均高于非肿瘤性病变,差异有统计学意义(P<0.05)。血管与表面结构分型的诊断准确率为85%,微血管密度评估的诊断准确率为64%,二者联合诊断准确率为95%,均高于单一诊断,差异有统计学意义(P<0.05)。结论放大内镜结合窄带成像下获得的微血管密度定性评估可作为血管与表面结构分型评估办法的补充内容,显著提高胃早期肿瘤性病变的诊断准确性。
