作者在390例X线显示的下食管粘膜环中,通过其中经内窥镜证实,并有1—5年X线随访资料的22例观察,探讨下食管粘膜环的产生和自然发展变化规律及有关因素。结果表明;22例中有2例原为正常,4年后出现下食管粘膜环;3例复查中粘膜环口变小;8例由粘膜环发展为食管下段狭窄。其余9例粘膜环无明显变化。发生变化的13例中,10例有不同程度的返流性食管炎(轻度2例,中度5例,重度3例)。粘膜环无明显变化的9例中,仅
In 390 cases of lower esophageal mucosal rings, the authors observed 22 cases of endoscopically confirmed X-ray follow-up data for 1 to 5 years to investigate the production and natural development of lower esophageal mucosal rings. Related factors. The results showed that 2 of the 22 cases were normal, and the lower esophageal mucosal ring appeared 4 years later. In 3 cases, the mucosal ring opening became smaller; 8 cases developed from the mucosal ring into the lower esophageal stenosis. The remaining 9 cases had no significant changes in the mucosal rings. Among the 13 cases that had changed, 10 cases had different degrees of reflux esophagitis (mild 2 cases, moderate 5 cases, severe 3 cases). In 9 cases with no significant changes in mucosal rings, only
