Straight leg raise (SLR) while supine increases intra‐abdominal pressure. We hypothesized that elevations in intra‐abdominal pressure would transmit into the thoracic cavity if the esophagogastric junction (EGJ) was disrupted.

在直腿上经食管胃交界处的压力梯度提高了高分辨率测压的动作，并伴有较大的裂孔疝。

直腿抬高（SLR），而仰卧则增加腹腔内压力。我们假设如果食管胃交界处（EGJ）破裂，腹腔内压力的升高将传导到胸腔。
