下食管环(Schatzki氏环)是一种薄的环状嵴,位于食管下端胃与食管间鳞-柱状上皮交界处。作者通过十年间18例住院病人的分析观察,发现这些病人的反流性食管炎与食管环的存在之间有着密切的联系。这些环经放射线检查与Schatzki,Gary所描述的相同:在食管下端有一薄的(≤4mm)多少有些对称性的膈样狭窄,其根部与食管长轴垂直,伴有食管裂孔疝,位于膈上5cm以内处。每个手术病例均能清楚显示在胃食管鳞-柱状上皮交接处有一个薄环。食管镜检查为食管炎表现:如粘膜有易脆性、红斑、表浅糜烂或平坦溃疡。上皮层内有白细胞则为具有组织学证据的食管炎。反流性食管炎与下食管环间的关系在过去是有争异的。有人认为反流与食管炎有时可以共 The lower esophageal ring (Schatzki’s ring) is a thin annular ridge located at the junction of the lower esophagus stomach and esophageal squamous-columnar epithelium. Through an analysis of 18 in-patient patients during the decade, the authors found a close relationship between reflux esophagitis and the presence of esophageal rings in these patients. These rings are the same radiographs as those described by Schatzki and Gary: A thin (<4 mm) somewhat symmetrical diaphragmatic stenosis at the lower end of the esophagus, with its root perpendicular to the long axis of the esophagus, with esophageal hiatal hernia, located on the diaphragm Within 5cm. Each surgical case clearly shows a thin ring at the junction of the gastroesophageal squamous-columnar epithelium. Esophagoscopy for esophagitis performance: such as mucosal fragility, erythema, superficial erosion or flat ulcers. Epithelial leukocytes are histologically proven esophagitis. Reflux esophagitis and the relationship between the lower esophageal ring in the past is controversial. Some people think that reflux and esophagitis can sometimes be total
