胃—食道反流(flu GER)在较早文献上称贲门—食道松弛,裂孔疝及先天性食道过短。近年来国外文献关于GER报告颇多,它可引起频发呕吐,慢性再发性肺炎,哮喘,呼吸困难、猝死等。国内对此报道尚少,本文目的在于提起人们对本病的认识与注意。一、定义远端食道功能异常,引起胃内容物经常反流入食道。二、GER发生机制(一) 食道低位括约肌(下称LES)为食道压力增高区,长约1～3cm。正常低位食道括约肌压力(下称LESP)为15～30mmHg,它在防止胃内容物反流入食道所起的重要性互有争论,1981年Ahtaridis对此进行研究,将研究对象分为三组:
Gastro-esophageal reflux (flu GER) in the earlier literature called cardia - esophageal laxity, hiatal hernia and congenital esophagus is too short. In recent years, foreign literature on the GER report quite a lot, it can cause frequent vomiting, chronic recurrent pneumonia, asthma, dyspnea, sudden death and so on. Domestic reports on this is still small, the purpose of this paper is to bring people’s awareness of the disease and attention. First, the definition of distal esophageal dysfunction, causing the stomach contents often reflux into the esophagus. Second, the mechanism of GER (a) esophageal low sphincter (hereinafter referred to as LES) esophageal pressure increase zone, about 1 ~ 3cm. Normal low esophageal sphincter pressure (LESP) of 15 ~ 30mmHg, its importance in preventing the reflux of gastric contents into the esophagus have been controversial, Ahtaridis in 1981 to study this research will be divided into three groups:
