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 (TcO-4). 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 TcO-4. In both, thyroid uptake was absent due to complete suppression of thyroid function by thyroid hormone supplements. TcO-4accumulated in thyroid glands of the other three patients, causing overlapping activity between the thyroid gland and HGM-UE. TcO-4scintigraphy is suitable for the detection of HGM-UE only in those patients who have had a total thyroidectomy or are on suppressive thyroid therapy. |
