To assess the relation of orifice orientation to recorded pressure within the lower esophageal high pressure zone (HPZ) in children, studies were performed on 12 normal subjects. Pressure was measured using a 3-lumen polyvinyl catheter. The lateral orifices of this catheter were uniformly spaced at every 120°interval at the same level of the circumference of the catheter. The catheter was continuously perfused with water by a constant infusion pump at the rate of 30 ml per hour. Resting pressure was recorded at the appropriate level by withdrawing the catheter from the stomach to the esophagus. There was a striking difference in these three recordings at the site of the entry into the HPZ, the point of the maxinum pressure of the HPZ, the maxinum pressure of the HPZ, and the total length of the HPZ, except the exit from the HFZ. The overall results of this study indicate clearly that the lower esophageal HPZ in children is not located in symmetrical position, and a catheter with side hole dose not record the overall intraluminal pressure within HPZ.
