The Role of Hepatic and Splanchnic Lymphatic System in Portal Hypertension and Ascites.

Purpose of Review: The lymphatic network plays a major role in maintaining tissue fluid homeostasis. Therefore, several pathological conditions associated with edema formation result in deficient lymphatic function. However, traditionally, the lymphatic system has been underestimated until recent years when it has been noticed the importance of this system in chronic liver disease. This review highlights the knowledge of lymphatic biology in the context of portal hypertension and liver cirrhosis. Recent Findings: Among different roles of lymphatic system in liver disease, two remarkable ones are the contribution in ascites accumulation and the hepatic lymphangiogenesis in portal hypertension which is regulated by sympathetic nerves. Summary: The identification of novel pathological mechanisms has focused efforts into correction of structural changes and function affecting lymphatic vessels in liver disease. Despite the knowledge gained, we still have to face many unresolved questions concerning the role played by the lymphatic system in chronic liver disease and the design of therapeutic targeting.
