Paracentesis is a Hepatology procedure during which fluid from the abdomen is removed through a needle. There are two reasons to take fluid out of the abdomen. One is to analyze it. The other is to relieve pressure. Liquid that accumulates in the abdomen is called ascites. Ascites seeps out of organs for several reasons related either to disease in the organ or fluid pressures that are changing.
