Multiple esophageal rings are a very unusual cause of dysphagia. We report a case of a 35-yr-old male with multiple esophageal rings and severe dysphagia, whose father had similar symptoms. Our patient underwent esophageal dilation on one occasion and is asymptomatic at 1-yr followup. We speculate that multiple esophageal rings may be of congenital origin.
多发性食管环是吞咽困难一种非常罕见的病因。我们报告一例35岁男性患者，患有多发性食管环并伴有严重吞咽困难，其父亲有类似症状。我们的患者曾接受过一次食管扩张术，在1年的随访中无症状。我们推测多发性食管环可能起源于先天性。
