[Partial liver resections with various laser types. Functional and morphologic results of an experimental study].

In an experimental study, partial liver resections were performed with a Nd-YAG-laser as well as with the combination of a CO2- and Nd-YAG-laser to prove the simultaneous cutting and hemostatic effect. Sufficient cutting efficiency could be achieved with a high power Nd-YAG-laser providing a mean output of more than 70 W; especially with a Nd-YAG-laser working with an unstable resonator due to a decreased spot size as used in the combined laser system.
