[Cryosurgery of the healthy rat liver]

Cryosurgical treatment was applied to normal liver tissue of 13 clinically intact rats, with a view to investigating effects of freezing temperatures upon normal liver tissue. The animals were sacrificed after different intervals from surgery, and their liver tissue was macroscopically and histologically examined. Major postoperative complications were not observed but for one animal which died of wound healing disorder. The method seems to be suitable also for treatment of liver cell carcinoma or liver metastases.
