[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 explore the clinical features of heterotopic gastric mucosa in the upper esophagus (HGMUE) with narrow band imaging (NBI) endoscopy in order to improve the detection rate of HGMUE. [Methods] Clinical, endoscopic and pathological findings of 113 patients with NBG endoscopic diagnosis of HGMUE were retrospectively analyzed. [Results] 113 of the 719 HGMUE patients were found, the detection rate of endoscopy was 2.39%. NBI endoscopic, lesions of the area of brown patches, with the surrounding normal esophageal epithelium clear boundaries, small concave shape to tubular (93.81%), no changes in surface microvascular dilatation. The clinical manifestations of some patients were retrosternal pain, burning sensation, swallowing difficulties, throat foreign body sensation and so on. The pathology was gastric epithelium and the gastric fundus (68.14%) was mostly. [Conclusion] NBI endoscopy can increase the detection rate of HGMUE, which can be helpful for clinical treatment.
