Upper oesophageal webs or rings have rarely been reported in association with heterotopic gastric mucosa (HGM).
To describe the finding of oesophageal webs in association with HGM.
Small case series.
Patients presenting with dysphagia to an open access hospital dysphagia clinic.
Six cases were found.
Symptomatic improvement is demonstrated with oesophageal dilatation in symptomatic patients.
Symptomatic improvement.
The six cases which are described here demonstrate that a web or ring exactly matches the distribution of the heterotopic mucosa, can occur at both proximal and distal squamo-columnar junctions and the inlet patches may be multiple with multiple rings. A radiological double web sign is described.
A rare condition with a small number of patients.
Effective treatment can be by oesophageal dilatation and acid suppression. The cause of web formation is thought to be due to heterotopic acid production and is analogous to the Schatzki ring.
上食管蹼或环与异位胃黏膜（HGM）相关的报道很少。
描述与HGM相关的食管蹼的发现。
小病例系列。
在一家开放式医院吞咽困难诊所就诊的吞咽困难患者。
发现6例。
有症状的患者通过食管扩张症状得到改善。
症状改善。
这里描述的6例病例表明，蹼或环与异位黏膜的分布完全匹配，可发生在近端和远端鳞状柱状交界处，入口斑可能有多个且伴有多个环。描述了一种放射学双蹼征。
一种罕见疾病，患者数量少。
有效的治疗方法可以是食管扩张和抑酸。蹼形成的原因被认为是由于异位酸的产生，类似于沙茨基环。
