The oesophageal vestibule lies immediately above the stomach and during quiet respiration is located partly in the thorax, partly in the hiatus in the diaphragm, and partly in the abdomen. An analysis of some aspects of function of the vestibule in infants and children who have a non-contractile gullet above the vestibule is presented. Opening of the vestibule is related to deglutition and is independent of the oesophagus above. In its opening and closing the vestibule is shown to have the characteristics of a `muscle throttle'. The rapidity of the event of either opening or closing is accounted for. The important relationship of calibre of lumen of the vestibule to flow through it is analysed. The effect of the indentations of mucosa into the lumen when the vestibule is partially open is analysed from a theoretical standpoint, and it is inferred that the vestibule when only partially open has the characteristics of a highly efficient choke.
食管前庭位于胃的正上方，在安静呼吸时，部分位于胸腔，部分位于膈肌裂孔处，部分位于腹腔。本文对食管前庭上方食管无收缩功能的婴幼儿食管前庭功能的某些方面进行了分析。食管前庭的开放与吞咽有关，且独立于上方的食管。研究表明，食管前庭在开闭过程中具有“肌肉节流阀”的特性。阐述了其开闭过程的快速性。分析了食管前庭管腔直径与通过其中的流体流量之间的重要关系。从理论角度分析了食管前庭部分开放时黏膜向管腔内凹陷的影响，并推断食管前庭仅部分开放时具有高效节流器的特性。
