Ten patients presenting with central chest pain and/or dysphagia were diagnosed to have oesophageal motility disorders (OMD) with an incoordinate motor function using computerised radionuclide oesophageal transit study (RT). The criteria for diagnosis of OMD with incoordination using RT were: an 'incoordinate' or 'to and fro' pattern characterised by multiple peaks of activity, prolonged total transit time or radionuclide bolus through entire length of oesophagus and a significant portion of bolus entering the stomach. These features are characteristic but not pathognomonic of diffuse oesophageal spasm (DES) as they are also seen in non-specific motility disorders (NSMD) and occasionally in order oesophageal motility disorders. Mechanical obstruction in the oesophagus and coronary artery disease were excluded appropriately in these patients. When manometry is not available, RT is a sensitive, safe, simple, rapid and non-invasive alternative modality in confirming certain oesophageal motility disorders.
10例表现为中央胸痛和/或吞咽困难的患者经计算机放射性核素食管通过研究（RT）诊断为食管动力障碍（OMD）且运动功能不协调。使用RT诊断不协调型OMD的标准为：“不协调”或“来回”模式，其特征为多个活动峰值、总通过时间延长或放射性核素团块通过食管全长以及相当一部分团块进入胃内。这些特征是弥漫性食管痉挛（DES）的特征性表现，但并非特异性表现，因为它们也可见于非特异性动力障碍（NSMD），偶尔也可见于有序性食管动力障碍。这些患者已适当排除食管机械性梗阻和冠状动脉疾病。当无法进行测压时，RT是确认某些食管动力障碍的一种敏感、安全、简单、快速且无创的替代方法。
