Five patients with patches of gastric fundal type columnar epithelium in the proximal esophagus at the level of the upper esophageal sphincter diagnosed by upper endoscopy underwent 99mTc-pertechnetate scintigraphy (TcO4-). In all instances, the patches contained both chief cells and mucus-secreting cells. One patient had dysphagia localized to the area of columnar epithelium. Two cases of heterotopic gastric mucosa in the upper esophagus (HGM-UE) were demonstrated by TcO4-. In both, thyroid uptake was absent due to complete suppression of thyroid function by thyroid hormone supplements. TcO4- accumulated in thyroid glands of the other three patients, causing overlapping activity between the thyroid gland and HGM-UE. TcO4- scintigraphy is suitable for the detection of HGM-UE only in those patients who have had a total thyroidectomy or are on suppressive thyroid therapy.
通过上消化道内镜检查诊断为食管上段括约肌水平近端食管有胃底型柱状上皮斑的5例患者接受了99m锝高锝酸盐闪烁扫描（TcO4-）。在所有病例中，这些斑片均含有主细胞和黏液分泌细胞。1例患者吞咽困难局限于柱状上皮区域。通过TcO4-证实了2例食管上段异位胃黏膜（HGM-UE）。在这2例中，由于甲状腺激素补充剂完全抑制了甲状腺功能，甲状腺摄取不存在。TcO4-在其他3例患者的甲状腺中积聚，导致甲状腺与HGM-UE之间出现重叠活性。TcO4-闪烁扫描仅适用于那些接受了甲状腺全切术或正在接受甲状腺抑制治疗的患者来检测HGM-UE。
