The effect of nutrition status and arginin on liver hypertrophy after portal vein embolization

Background/Purpose: In patients with various kinds of liver tumors resection is the only treatment method, which can provide long term survival. If the residual liver (future liver remnant-FLR) after the planned resection is less than 30–40% (normal liver-cirrhosis) of the total liver, portal vein occlusion of the tumorous liver lobe can hypertrophise the contralateral lobe. A key step in this process is nitrogen monoxide (NO), which origins from L-arginine through NO synthase. The effect of nutritional status, body composition and arginine supplementation of normal feeding on the liver hypertrophy after portal…
