With the development of science and technology, the treatment of liver cancer is also relatively strong there have been many new targeted therapy, laser treatment for liver cancer is a relatively strong for the HCC cell treatment.
1. Liver function principle of laser therapy
Of biological tissue with laser heat, pressure, light and the role of electromagnetic effects. By direct irradiation of high power focused laser foci, cancer can quickly become aerosol, thereby eliminating the cancer. At present, Qin Ji by high-power doped aluminum garnet (Nd: YAG) solid-state laser.
2. Hepatocellular carcinoma indication of laser therapy
(1) multiple liver nodules;
(2) with severe liver cirrhosis in the right Ye;
(3) smaller than the recurrence of liver cancer.
3. Hepatoma specific steps of laser therapy
Use non-explosive anesthetic. The first liver surgery in the first block the door, O.5-3cm in diameter around the cancer nodules by direct vaporization method. Lcm from the outer edge of vaporization at the beginning of nodules, were from outside to inside, to open the blood circulation throughout the nodules disappeared, the general diameter of 2mm thermal coagulation of blood vessels can be closed, the active bleeding wound re-defocusing photocoagulation 1 on the individual small arteries branch should be ligated to stop bleeding. Defects caused by vaporization, without bleeding, may not be dealing with "the cancer of diameter greater than 3cm, most people Liver laser cutting, the section dealing with larger vessels to stop bleeding and used car operation. Postoperative inflammatory reaction is not heavy.
