The relationship between the diaphragmatic hiatus, the infra-diaphragmatic esophagus and a manometric tube were examined in 10 patients not suffering from hiatal hernia or gastroesophageal reflux. During surgery, two metal markers were attached to the diaphragmatic hiatus and two others were fixed at the vertex of the angle of His. X-ray examinations were taken during manometric recordings of the high pressure zone (HPZ) both at rest and during relaxation. Comparison between the radiographs showed that during swallowing the manometric tube did not move with respect to the vertebral bodies; contraction of the esophagus caused complete disappearance of the infra-diaphragmatic esophagus. It was also observed that during pressure drop in the HPZ (so-called lower esophageal sphincter relaxation), the manometric recording site is located below the vertex of the angle of His, i.e. in the gastric cavity. These findings provide the basis for a hypothesis to explain the passage of a solid bolus through the lower esophagus into the stomach.
在10例未患食管裂孔疝或胃食管反流的患者中，研究了膈裂孔、膈下食管与测压管之间的关系。手术过程中，在膈裂孔处附着两个金属标记物，另外两个固定在希氏角顶点。在静息和放松状态下对高压区（HPZ）进行测压记录时进行X线检查。X线片对比显示，吞咽时测压管相对于椎体没有移动；食管收缩导致膈下食管完全消失。还观察到，在HPZ压力下降（即所谓的食管下括约肌松弛）期间，测压记录部位位于希氏角顶点下方，即在胃腔内。这些发现为解释固体食团通过食管下段进入胃内的过程提供了假设依据。
