[Influence of proximal gastric vagotomy on the esophageal high pressure zone in dogs].
The influence of parietal cell vagotomy (PCV) on esophagogastric high pressure zone (HPZ) (pressure and length) was studied in 30 dogs. The animals were divided in 3 groups: group 1, 10 dogs submitted to PCV with gastric denervation until the esophagogastric junction; group 2, 10 dogs submitted to PCV with gastric denervation into esophagogastric junction and 3 cm above this; group 3 (control), 10 dogs submitted to laparotomy only. In the postoperative period (immediate and later) it wasn't observed any alteration of pressure and length of esophagogastric HPZ in three studied groups.
