胃—食道返流是食道粘膜损伤最常见的原因,但仅有少数病人产生良性食道狭窄。食道粘膜损伤和胃—食道返流之间没有肯定的关系,这说明可能存在其它的触发因素。本文报道了是否服用过非类固醇抗炎药物(NSAI)的良性食道狭窄病人在年龄、性别上进行配对比较的结果.发现53例病人中的26例(49％),在产生吞咽困难就诊前一年服用了NSAI(如消炎痛、阿斯匹灵、炎痛喜康等)。10例(19％)在同一时间曾服用对食道疾病有影响的其 Gastro-oesophageal reflux is the most common cause of esophageal mucosal injury, but only a few patients have benign esophageal stenosis. There is no positive relationship between esophageal mucosal injury and gastro-oesophageal reflux, suggesting that there may be other triggers. This article reports the results of paired comparisons of age and sex among patients with benign esophageal stenosis who took non-steroidal anti-inflammatory drugs (NSAI). Found 26 (49%) of 53 patients before swallowing difficulty. She took NSAI (such as indomethacin, aspirin, and piroxicam, etc.). Ten patients (19%) had taken the same effect on esophageal disease at the same time.
