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.
对19例进行性系统性硬化症（PSS）患者进行了放射性核素食管通过时间（ET）研究，并进行了3至5年的纵向随访。结果以20秒和10分钟时的滞留百分比表示。20秒和10分钟时的ET均逐渐恶化。当将结果分为四分位数时，在最初20秒滞留可能恶化的患者中，58.5%的随访研究出现恶化；在10分钟滞留方面，类似患者中有48%出现恶化。
