Nd-YAG laser for general surgery.

We report here our clinical experiences with Nd-YAG laser on general surgery, and evaluate the results of this procedure. From December 1979 to December 1981, we applied Nd-YAG laser to various operations as a hemostatic and cutting tool. For hemostasis, we used conventional quartz fiber which was covered with sterile tube, and hemostatic efficacy was examined especially in the subcutaneous bleeding and the bleeding from solid organs. For cutting, we used special devices, ie, Medilas YAG surgical probe (noncontact-type probe), and a laser blade (contact-type probe), and performed four liver resections. It is concluded that the hemostatic efficacy of Nd-YAG laser to various bleeders was proved in general surgical procedures, and furthermore this laser can cut tissue if we utilize these devices. When comparing these two devices, we would prefer the contact-type probe.
