[Cardial function after a proximal gastric vagotomy].

We realize this study with the purpose of verifying if the cardias is affected or not by the proximal gastric vagotomy. Thirty six (36) patients suffering from chronic recurrent duodenal ulcer without complications were examined in sucession immediately before the operation and also three and twelve months after operation. The PGV was carried out without drainage. Only two cases needed pyloroplasty (Finney Type) due to stenosis of the pylorus. The completeness of the vagotomy was comprobated through the insulin test which was made three months postoperatively. This was obtained in 89% of the cases. We took 12 volunteers that they were not suffering from known disease of esophagus or stomach. The tests made to observe the function of the cardias after the proximal gastric vagotomy (PGV) were: Manometry, pH metry and Endoscopy/Histology. The obtained results are established. The conclusions of this work are drawn.
