One thousand consecutive cinefluorographic examinations of the hypopharynx and cervical esophagus were reviewed to determine the incidence of webs in a population routinely referred for upper gastrointestinal examination. The age, sex, and incidence of iron deficiency anemia in patients with webs were compared with those of the controls, and dysphagia and associated diseases were noted. 5.5% of the patients had one or more webs; these patients had a similar sex distribution to the control group but were generally older. Both groups had the same incidence of iron deficiency anemia. None of the patients with webs met the criteria for Plummer-Vinson syndrome. The authors believe that most cervical esophageal and hypopharyngeal webs are of no clinical significance.
回顾了1000例连续的下咽和颈段食管的荧光电影造影检查，以确定在常规接受上消化道检查的人群中网织的发生率。将有网织的患者的年龄、性别和缺铁性贫血发生率与对照组进行比较，并记录吞咽困难及相关疾病。5.5%的患者有一个或多个网织；这些患者的性别分布与对照组相似，但年龄普遍较大。两组缺铁性贫血的发生率相同。没有一个有网织的患者符合普卢默-文森综合征的标准。作者认为，大多数颈段食管和下咽网织无临床意义。
