We utilized the reinfusion technique developed for treatment of intractable ascites in liver cirrhosis for treatment of intractable ascites in three patients with terminal gynecologic malignant tumor. The re-infusion of the cell-free, concentrated ascitic fluid was effective and the BUN, uric acid and excessive minerals were removed from the serum and yet the total protein was unchanged. This treatment leads to symptomatic relief and prolongs the survival time.
