High-resolution ultrasound (US) showed that initial peristalsis propelled ingested soda smoothly and rapidly in 20 volunteers without symptoms who met both manometric and radionuclide esophageal scintigraphic (RES) criteria for normal motility. Twenty-eight patients with progressive systemic sclerosis were classified according to results of RES as follows: group 1, normal esophageal motility (three patients [11%]); group 2, hypomotility of the esophagus, excluding the cervical esophagus (18 patients [64%]); and group 3, hypomotility of the cervical esophagus (seven patients [25%]). In the seven patients of group 3, US demonstrated that an incomplete peristalsis sequence or a feeble peristalsis propelled the soda in a slow and/or to-and-fro motion with low velocities. In the other 21 patients (75%), the soda passed through the esophagus smoothly and rapidly. Retention of soda in the cervical esophagus was not limited to patients with hypomotility of the cervical esophagus. It is concluded that US is useful in evaluation of cervical esophageal motility.
高分辨率超声（US）显示，在20名符合测压和放射性核素食管闪烁显像（RES）正常蠕动标准且无症状的志愿者中，最初的蠕动能顺利且快速地推动摄入的苏打水。28例进行性系统性硬化症患者根据RES结果分类如下：第1组，食管蠕动正常（3例[11%]）；第2组，食管动力减退，不包括颈段食管（18例[64%]）；第3组，颈段食管动力减退（7例[25%]）。在第3组的7例患者中，超声显示不完全蠕动序列或微弱蠕动以缓慢和/或来回运动且速度较低的方式推动苏打水。在其他21例患者（75%）中，苏打水顺利且快速地通过食管。苏打水在颈段食管的潴留并不局限于颈段食管动力减退的患者。结论是超声在评估颈段食管蠕动方面有用。
