窄波成像与白光内镜在胃食管反流病诊断中作用比较

目的比较窄波成像（narrow band imaging,NBI）与白光内镜（white light endoscopy,WLE）在胃食管反流病诊断中的作用。方法 159例胃食管反流病患者,先应用WLE然后切换到NBI模式,观察鳞柱状上皮结合处附近黏膜破损情况。结果非糜烂性反流病诊断率NBI（54.72%）低于WLE（71.70%）（P〈0.05）;LA-A级反流性食管炎诊断率NBI（33.33%）高于WLE（20.13%）（P〈0.05）;LA-B、LA-C、LA-D级反流性食管炎诊断率在NBI分别为9.43%、1.87%、0.63%,在WLE分别为5.66%、1.87%、0.63%,差异均无统计学意义（P〉0.05）。结论 NBI用于LA-A级反流性食管炎诊断优于WLE。

Utility of white light endoscopy and narrow-band imaging in the endoscopic diagnosis of gastroesophageal reflux disease

Objective To compare narrow-band imaging（NBI）with white light endoscopy（WLE）in the diagnosis of gastroesophageal reflux disease.Methods A total of 159 patients with gastroesophageal reflux disease were firstly examined by WLE,followed by NBI mode to evaluate the mucosal break at squamous columnar junction（SCJ）.Results The diagnosis rate of nonerosive reflux disease by NBI was 54.72%,significantly lower than that by WLE（71.70%）（P〈0.05）.The diagnosis rate of reflux esophagitis by NBI was 33.33%,significantly higher than that by WLE（20.13%）（P〈0.05）.There were no significant differences in the diagnosis rates of LA-B,LA-C and LA-D reflux esophagitis by NBI（9.43%,1.87%,0.63%）in comparison with those by WLE（5.66%,1.87%,0.63%）（P〉0.05）.Conclusion NBI is superior to WLE for LA-A reflux esophagitis.
