Liver

Abstract

The liver arises from the foregut-midgut junction. It is contained in the Glisson capsule, and the falciform ligament attaches the liver to the anterior abdominal wall. Hepatocytes perform approximately 500 functions. Chronic hepatitis C, alcoholic liver disease, and nonalcoholic steatohepatitis may cause cirrhosis and give rise to liver failure and potentially HCC. MRI, CT, and US are helpful for determining the extent of cirrhosis and detecting ascites, tumors, and blood flow. Fifty percent to 80% of the liver can be resected if the remainder functions well. Liver resections may bleed, leak bile, or lead to infection.
