[Surgical treatment of portal hypertension in children (author's transl)].

Various operative techniques are employed for the surgical treatment of portal hypertension in children. Operations to reduce oxygen supply are briefly described, followed by a more detailed study of procedures for azygoportal disconnection which include endoscopic sclerosis, direct varices ligature, transection of the oesophagus and stomach, or gastro-oesophageal resection. Operations to obtain a portal vein blood shunt by portosystemic anastomosis are described more fully, these including radicular shunts involving capillary anastomoses between the portal and systemic systems, radicular shunts and more particularly splenorenal and mesentericocaval anastomoses, and those employing an interposed graft. Truncal shunts have also been employed in the different types of portocaval anastomoses, and those employing an interposed graft. Truncal shunts have also been employed in the different types of portocaval anastomosis. So-called mixed operations concern either oesophageal devascularisation procedures or radicular anastomosis, the prototype for the latter being Warren's operation.
