摘要 目的:通过分析放大胃镜结合窄带成像技术(NBI)在早期胃癌中的诊断价值。方法:我院胃镜室自2011年2月至2013年5月经普通白光内镜检查4206例,发现疑似早期胃癌的患者49例,分别进行放大内镜、NBI放大内镜检查,对疑似病灶的胃粘膜在形态、色泽及微血管形态的清晰度进行比较,并对疑似部位进行活检送病理学检查。结果:49例患者中经病理组织学检查诊断为早期胃癌26例。NBI放大内镜与电子放大内镜在观察粘膜腺管结构显示方面无统计学意义(P>0.05)。在观察微血管形态方面,NBI放大内镜明显好于电子放大内镜。在诊断早期胃癌的敏感度、特异度以及病理组织学的符合率方面,NBI放大内镜分别为91.6%(11/12)、94.6%(35/37)、95.9%(47/49),电子放大内镜分别为58.3%(7/12)58.3%(29/37)78.4%(37/49)。NBI放大内镜诊断早期胃癌的准确性明显高于电子放大内镜。结论:电子放大内镜是早期胃癌筛查首选的检查方法,对疑似病变进一步进行NBI检查可以更方便地提供清晰的血管图像,有助于早期胃癌的诊断,提高检出率。
