For the first time patients underwent palliative operations or diagnostic laparotomy.

[Cryosurgery of hepatic tumors].

The work presents an experience with cryosurgical treatment of malignant and benign tumors of the liver in 110 patients. The cryosurgery was performed using an original apparatus. The methods of resection of the liver using cryosurgical instruments are described which reduce the intraoperative blood loss and facilitate visualization of the vascular-tubular structures along the resection line.
