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。
Objective To compare the role of narrow band imaging (NBI) and white light endoscopy (WLE) in the diagnosis of gastroesophageal reflux disease. Methods A total of 159 patients with gastroesophageal reflux disease were treated with WLE and then switched to NBI mode to observe mucosal damage near the columnar epithelium. Results The diagnostic rate of non-erosive reflux disease was lower than that of WLE (54.72%) (P <0.05). The diagnostic rate of LA-A reflux esophagitis was 33.33% higher than that of WLE (20.13% (P0.05). The diagnostic rates of LA-B, LA-C and LA-D reflux esophagitis were 9.43%, 1.87% and 0.63% respectively in NBI and 5.66%, 1.87% and 0.63% , There was no significant difference (P> 0.05). Conclusion NBI is superior to WLE in diagnosing LA-A reflux esophagitis.
