Islets of heterotopic gastric mucosa can occur in the whole alimentary tract as well as in the gallbladder, the extrahepatic bile ducts and the pancreatic tissue. In most cases they have incidentally been discovered in autopsies and surgical specimens. Ectopic gastric mucosa is known to cause gastrointestinal bleeding in Meckel's diverticulum and duplications of the intestine, and, in exceptional cases may show a malignant transformation. In endoscopy of the gastrointestinal tract ectopic gastric epithelium can often be conjectured from certain morphological phenomena. In this paper we review pathogenesis, localization, clinical significance as well as diagnostic and therapeutic aspects of heterotopic gastric mucosa.
异位胃黏膜岛可出现在整个消化道以及胆囊、肝外胆管和胰腺组织中。在大多数情况下，它们是在尸检和手术标本中偶然发现的。已知异位胃黏膜会导致梅克尔憩室和肠道重复畸形出现胃肠道出血，在极少数情况下可能会发生恶性转化。在胃肠道内镜检查中，常可根据某些形态学现象推测出异位胃上皮。本文将对异位胃黏膜的发病机制、定位、临床意义以及诊断和治疗方面进行综述。
