Shunt surgery for treatment of portal hypertension in children

Shunt surgery in children suffering from portal hypertension (PH) is considered as an immediate and definite mode of prevention of recurrent gastrointestinal hemorrhage. Certain conditions must be met: (a) normal liver; (b) normal veins available within the portal system; (c) a sufficient portosystemic gradient of pressure; and (d) a surgical team with experience in portal venous surgery. In patients in whom PH is an epiphenomenon of severe liver disease, other means of hemostasis for bleeding esophageal varices should be sought. The difficult decision is in the child with specific liver alterations without major hepatocellular dysfunction but in whom the prognosis cannot be precisely foreseen. A few more years will be needed before one can tell if shunt surgery is the best choice for this category of patient.
