Scintigraphic technique was used to study esophageal transport of a solid bolus in 16 patients with dysphagia but with normal manometry, and negative acid perfusion tests, acid clearing tests, and pH reflux tests. Radiology performed on 14 of the 16 patients showed no evidence of organic lesions. Half the patients had abnormal findings at scintigraphy, with either bolus retention in the upper part of the esophagus or prolonged transit time as compared to a group of 20 asymptomatic subjects. Scintigraphy can be regarded as a valuable complement in the objective documentation of dysphagia when other diagnostic methods fail.
采用闪烁扫描技术对16例吞咽困难但测压正常、酸灌注试验、酸清除试验及pH反流试验均为阴性的患者进行固体食团食管转运研究。16例患者中的14例进行的放射学检查未发现器质性病变证据。与20名无症状受试者相比，一半的患者闪烁扫描有异常表现，表现为食管上部食团滞留或转运时间延长。当其他诊断方法失败时，闪烁扫描可被视为吞咽困难客观记录中有价值的补充手段。
