This study, evaluating the effects of hyperthyroidism (HT) in oesophageal motility, depended on an oesophageal radionuclide transit test. A modified standard method was used to calculate: (a) total mean transit time (MTT), (b) residual fraction (RF) and (c) retrograde index (RI) in a supine position. Eighteen untreated patients with HT and 25 normal volunteers (NV) with a similar age distribution were included in this study. The results showed that oesophageal motility in patients with HT was worse than in the normal controls (P < 0.05 by Student's t-test). The correlation of MTT, RF and RI with size and function of thyroid glands in the patients with HT were calculated to explain the effects of HT in oesophageal motility. The results showed that neither the size nor the function of the thyroid glands in HT affected oesophageal motility.
本研究通过食管放射性核素转运试验评估甲状腺功能亢进症（HT）对食管动力的影响。采用改良的标准方法计算仰卧位时的：（a）总平均转运时间（MTT）、（b）残留分数（RF）和（c）逆行指数（RI）。本研究纳入了18例未经治疗的HT患者和25例年龄分布相似的正常志愿者（NV）。结果显示，HT患者的食管动力比正常对照组差（Student t检验，P < 0.05）。计算HT患者MTT、RF和RI与甲状腺大小及功能的相关性，以解释HT对食管动力的影响。结果显示，HT患者甲状腺的大小和功能均不影响食管动力。
