摘要 目的观察内镜阴性的胃食管反流病即非糜烂性反流病(NERD)患者食管黏膜鳞状上皮细胞间隙的宽度及食管下段黏膜固有肌层中肥大细胞的数量,并探讨其意义。方法 43例NERD患者(NERD组),同时将健康体检者10例作为阴性对照组,两组在胃镜下取黏膜活组织标本(包含黏膜下固有肌层),用固定液固定,经病理学常规取材、切片、染色等方法处理后,在光学显微镜下测量食管黏膜鳞状上皮细胞间隙的宽度,计数食管下段黏膜固有肌层中的肥大细胞,并对两组进行比较。结果 NERD组、阴性对照组食管黏膜鳞状上皮细胞间隙分别为(1.38±0.16)、(0.84±0.04)μm,肥大细胞数量分别为(3.24±0.67)、(1.32±0.29)个,两组比较,P均<0.01。NERD患者食管黏膜鳞状上皮细胞间隙与肥大细胞数量呈正相关(r2=0.576,P<0.01)。结论 NERD患者食管黏膜鳞状上皮细胞间隙增宽,食管下段黏膜固有肌层中肥大细胞数量增多。
