Description

Changes of the vascular pattern were investigated in patients with chronic liver disease using magnifying laparoscope, and were compared with histological finding. The earliest vascular change observed on the liver surface was an increased number of portal veins, which, however, decreased with the progression of disease, particularly in advanced liver cirrhosis. By contrast, the portal vein increased in size in liver cirrhosis. The features of arteriole, such as an increase in number, tortuosity, and network formation, were characteristically seen in advanced cirrhosis. Increased number of portal veins with few arterioles were the principal laparoscopic finding in patients without esophageal varices, whereas decreased number of portal veins with increased arterioles were seen predominantly in patient with esophageal varices. It is concluded that capsular vasculature in chronic liver disease is closely related to the intrahepatic derangement, by means of which magnifying laparoscopic feature can be shown to be a highly relevant indicator to the diagnosis of chronic liver disease.
