The aim of this study was characterized sin duodenum the heterotopic gastric mucosa.
The slides with the diagnosis of heterotopic gastric mucosa during 2014-2015, were reviewed, and clinical, histological and endoscopic data was to collected for every case.
45 cases of heterotopic gastric mucosa in duodenum were found, 91.1% were located in duodenum bulb and 73.2%, presenting as polyps in 73.2% of cases. In all cases, parietal cell was identified as main criteria for the diagnosis. Neither Helicobacter pylori nor dysplasia were identified.
Our data confirm its non neoplastic nature. Heterotopic gastric mucosa should be taken into account in diagnosis of duodenal polyps. Parietal cells identification in duodenal mucosa is essential in differential diagnosis with peptic duodenitis.
本研究旨在对十二指肠异位胃黏膜进行特征描述。
回顾2014 - 2015年诊断为异位胃黏膜的切片，并收集每例病例的临床、组织学和内镜数据。
发现45例十二指肠异位胃黏膜，91.1%位于十二指肠球部，73.2%表现为息肉。所有病例均以壁细胞作为主要诊断标准。未发现幽门螺杆菌和发育异常。
我们的数据证实了其非肿瘤性质。十二指肠息肉诊断时应考虑异位胃黏膜。十二指肠黏膜中壁细胞的识别对于与消化性十二指肠炎症的鉴别诊断至关重要。
