paracentesis

paracentesis is a procedure in which a needle is inserted through the abdominal wall to remove fluid that has built up in the abdominal cavity (ascites). it may be used as a test (diagnostic paracentesis) or as a treatment (therapeutic paracentesis).

paracentesis may be done to:

  • collect a fluid sample from the abdominal cavity to help find out the cause of ascites (diagnostic).
  • diagnose infection in the ascitic fluid (diagnostic).
  • remove a large amount of fluid from the abdominal cavity when the fluid is causing discomfort or affecting the function of the kidneys or intestines (therapeutic).
