The purpose of this paper is to study by means of intraoperative manometrics how to create the lower esophageal high pressure zone (HPZ). Sixteen patients with severe gastroesophageal reflux (two months to 15 years old) were selected and their esophagogastric junction were reconstructed by Boerema-Filler procedure. The lower esophageal HPZ were measured seven times before and during the operation, including after mobilizing the lower esophagus, after tying the right crus of the diaphragm, after fixing the lower esophagus to the anterior edge of the esophageal hiatus, after creation of His angle by Filler procedure, and so on. The following results were obtained: The tone of HPZ was mainly created by the mobilization of the lower esophagus and tying the right crus, and the lenght of HPZ was solely created by the mobilization and fixation of the lower esophagus.
