窄带成像内镜诊断食管上段胃黏膜异位症的临床分析

Clinical analysis of heterotopic gastric mucosa in the upper esophagus diagnosed by narrow band imaging endoscopy

[目的]探讨窄带成像(narrow band imaging,NBI)内镜诊断的食管上段胃黏膜异位症(heterotopic gastric mucosa in the upper esophagus,HGMUE)的临床特点,以提高HGMUE的检出率。[方法]回顾性分析NBI内镜诊断为HGMUE的113例患者临床、内镜、病理表现。[结果]4 719例患者中发现HGMUE患者113例,内镜检出率为2.39%。NBI内镜下,病变区域为棕褐色斑块,与周围正常食管上皮界限清晰,小凹形态以管状(93.81%)为主,未发现表面微血管扩张变异。部分患者临床表现为胸骨后疼痛、烧灼感、吞咽困难、咽部异物感等,病理为胃上皮组织,胃底型(68.14%)居多。[结论]NBI内镜可提高HGMUE的检出率,从而为临床治疗提供帮助。

[Objective]To investigate the clinical features of heterotopic gastric mucosa in the upper esophagus（HGMUE）diagnosed by narrow band imaging（NBI）endoscopy.[Methods]The clinical manifesta‐tions ,endoscopic features and the histological characteristics of HGM UE patients in the Wuhan central hospital from 2013 to 2014 were retrospectively analyzed.[Results]Total 113 cases were diagnosed HG‐MUE by NBI endoscopy in 4 719 patients.The detection rate of HGMUE was 2.39%.Some patients had the clinical symptoms of retrosternal pain ,heartburn ,dysphagia ,globus sensation ,hoarseness ,et al.The pa‐thology of tissues was gastric epithelium.Fundic‐type gastric mucosa（68.14% ）constituted the most com‐mon histology.[Conclusion]The use of NBI endoscopy can improve the detection rate of HGMUE which may help the secondary step of clinical treatment.
