目的 探讨食管除蠕动外还具有的“即时功能”。方法 对110名成人进行钡丸加水冲服试验,在X线透视下测定钡丸通过食管全程至入胃时间。结果 ≤2S13例,占11.8％;2～3S 92例,占83.7％;>3S5例,占4.5％。结论 吞咽后食管具有瞬间全程开放及其在开放时所产生的负压对食团的内吸作用。
Objective To investigate the “immediate function” of esophageal peristalsis besides peristalsis. Methods A total of 110 adults were treated with barium balls and water, and the barium pellets were passed through the esophagus and into the stomach under fluoroscopy. Results ≤ 2S 13 cases, accounting for 11.8%; 2 ~ 3S 92 cases, accounting for 83.7%;> 3S5 cases, accounting for 4.5%. Conclusions After swallowing, the esophagus has an instant full opening and the negative pressure exerted by the esophagus on opening the bolus.
