The lower esophageal ring, or Schatzki's ring, consists of a thin, submucosal, circumferential scar which forms a thin incomplete diaphragm in the lower esophageal lumen. The symptoms may be either episodic aphagia or progressive dysphagia, and the severity of symptoms is related to the diameter of the ring. Between 1970 and 1978, we saw 24 patients with lower esophageal rings and complaints of episodic aphagia or progressive dysphagia. Symptoms of esophagitis were present in 20 of the 24. Twenty were treated surgically by interrupting the rings and repairing the sliding hiatal hernias. Two were treated by dilatation and two received no treatment to the ring. Hiatal hernias have recurred in two patients. In one, there is a recurrent ring and in the other, an acid peptic stricture. The ring has responded to dilatation and the peptic stricture to dilatation and repair of the recurrent hernia. Two patients without symptoms of esophagitis, treated by dilatation, are doing well but the follow-up period is so far too short to draw any conclusion.
食管下环，即沙茨基环，由一层薄的黏膜下环形瘢痕组成，在食管下段管腔内形成一个薄的不完整隔膜。症状可能是发作性吞咽困难或进行性吞咽困难，症状的严重程度与环的直径有关。1970年至1978年期间，我们诊治了24例有食管下环且有发作性吞咽困难或进行性吞咽困难主诉的患者。24例中有20例存在食管炎症状。20例接受了手术治疗，切开环并修复滑动性食管裂孔疝。2例接受了扩张治疗，2例未对环进行治疗。2例患者出现食管裂孔疝复发。其中1例复发了环，另1例出现了酸性消化性狭窄。环对扩张治疗有反应，消化性狭窄对扩张及复发性疝的修复有反应。2例无食管炎症状且接受扩张治疗的患者情况良好，但随访期至今过短，无法得出任何结论。
