title: Oesophageal motility disorders: rapid functional diagnosis using computerised radionuclide oesophageal transit study.
abstract: 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.
