Heterotopia is understood as the occurrence of locally atypical tissue. Heterotopic gastric mucosa may occur throughout the whole GI-tract. In an unselected series of upper GI-endoscopies 6.3% of heterotopic gastric mucosa could be detected. Main localisation was the upper esophagus with 70%, followed by the duodenal bulb with approximately 25%. In 86% histological proof of ectopic mucosa was possible. In the esophagus the lesion looks like a red spot, in the duodenal bulb in contrast more like polypoid formations without discoloration. In our experience there is no significant relation of heterotopic mucosa to clinical symptoms. The clinical significance of heterotopic gastric mucosa however may be underscored by its possible complications.
异位是指局部出现非典型组织。异位胃黏膜可出现在整个胃肠道。在一组未经筛选的上消化道内镜检查中，可检测到6.3%的异位胃黏膜。主要定位在食管上段，占70%，其次是十二指肠球部，约占25%。86%的病例可通过组织学证实异位黏膜。在食管中，病变表现为一个红色斑点，相比之下，在十二指肠球部更像是无变色的息肉样结构。根据我们的经验，异位黏膜与临床症状之间没有显著关系。然而，异位胃黏膜的临床意义可能因其可能的并发症而得到凸显。
