Biochemical, hematologic, and immunologic alterations following hepatic cryotherapy.
Hepatic cryosurgery causes hepatocellular damage primarily by inducing the formation of ice crystals. Cell necrosis is enhanced using two or more freeze-thaw cycles. The resultant damage to hepatocytes induces alterations in a number of biochemical and hematologic parameters, including hepatic function tests, serum bilirubin, serum and urine myoglobin, platelet count, and coagulation measures. Further, in experimental models, cryogenic surgery appears to stimulate the immune system of the host leading to an anti-tumor immune response. These perturbations in biochemical and hematologic parameters are usually transient, and long-term adverse sequelae are uncommon and preventable.
