In 12 patients the endoscopic examination raised the suspicion of Barrett's syndrome. By means of guided biopsies and static scintigraphy with gamma camera and 99m-technetium pertechnetate ectopic gastric mucosa was found in the esophagus of 5 of the patients. In one patient a Barrett's ulcer was found. The establishment of a focus of increased radioactivity proximal from the stomach by static scintigraphy is a proof for the presence of ectopic gastric mucosa in the esophagus. Because of the high risk of malignancy a systemic endoscopic biopsy control is necessary for the patients with proved columnar-cell metaplasia in the esophagus.
12例患者经内镜检查怀疑患有巴雷特综合征。通过引导活检以及使用伽马相机和高锝酸盐99m锝进行静态闪烁扫描，在5例患者的食管中发现了异位胃黏膜。1例患者发现了巴雷特溃疡。通过静态闪烁扫描在胃近端确定放射性增强的病灶，是食管存在异位胃黏膜的证据。由于恶性风险高，对于已证实食管存在柱状上皮化生的患者，必须进行系统性内镜活检控制。
