It has been shown that the ACAP causes significant increases in the LES pressure of supine primates which are maximal when properly placed at the EGJ. This effect appears to be due to posterior padding of the EGJ in supine animals and can be reproduced by dowel rods or Maloney dilators. Further studies to evaluate the contribution of this effect to the prevention of acid reflux are underway.
研究表明,气囊抗反流假体(ACAP)可使仰卧位灵长类动物的下食管括约肌(LES)压力显著升高,当正确放置于食管胃连接部(EGJ)时压力达到最大。这种效应似乎是由于仰卧位动物的EGJ后部有衬垫,并且用定位棒或马洛尼扩张器也可重现这种效应。目前正在进行进一步研究,以评估这种效应对预防胃酸反流的作用。
