Abstract
Nineteen patients with progressive systemic sclerosis (PSS) were studied by radionuclide esophageal transit (ET) and followed longitudinally for 3 to 5 years. Results were expressed as percent retention at 20 s and 10 min. There was gradual deterioration of ET at both 20 s and 10 min. When results were grouped into quartiles, deterioration occurred in 58.5% of followup studies in patients who initially had potential to deteriorate regarding 20 s retention and in 48% of similar patients regarding 10 min retention.
