To evaluate the mean transit time of a solid bolus in 17 patients with prolonged acid clearing, a scintigraphic non-invasive technique was used. Sticking of the bolus in the middle third of the oesophagus was a common feature in these patients as compared with normals. Thus, the deteriorated transport pattern of a solid bolus in patients with prolonged acid clearing is not acidification-dependent. The catheter-intubated oesophagus showed a significantly (p less than 0.01) lower tendency for sticking as compared with prior intubation, whereas acidification of the oesophagus increased the sticking tendency significantly (p less than 0.01) as compared with the intubated oesophagus without acid. The evaluation of mean transit times was of no value because of the frequency of sticking. The fact that intubation improves the passage must be kept in mind when studies of solid bolus are performed in intubated patients.
为评估17例酸清除时间延长患者中固体团块的平均通过时间，采用了一种闪烁扫描非侵入性技术。与正常人相比，团块在食管中三分之一处滞留是这些患者的一个常见特征。因此，酸清除时间延长患者中固体团块的运输模式恶化并非依赖于酸化。与插管前相比，插管食管的滞留倾向显著降低（p<0.01），而与未酸化的插管食管相比，食管酸化显著增加了滞留倾向（p<0.01）。由于滞留频繁，平均通过时间的评估没有价值。在插管患者中进行固体团块研究时，必须牢记插管可改善通过这一事实。
