  • Title: [Research on intrazygoportal disconnection by use of Vosschulte's ring. Experimental study in the dog].
    Author: Germain M, Martin E.
    Journal: J Chir (Paris); 1976 Mar; 111(3):377-88. PubMed ID: 956293.
    Abstract:
    The disappointing results of porta-caval anastomosis in the treatment of portal hypertension have led surgeons to treat directly oesphageal varices by interazygoportal disconnection through Vosschulte's ring. An experimental study on 29 dogs, permitted the authors to make several discoveries. The ring introduced through the pylorotomy should have a caliber identical to that of the oesphagus. The course of the stricture then occurs towards mutilant annular fibrosis of all the oesphageal wall. The marked morbidity due to regurgitation linked to stenosis, may be reduced by early instrumental dilatation.
