The laser has established a strong position in the field of tumor surgery. The endoscopic modalities of tumor coagulation in particular have been developed so far, that in some cases even tumors in anatomically difficult locations or inoperable tumors can be coagulated interstitially. The Nd:YAG laser is well suited to this technique due to its good coagulation properties and the transmissiblity through flexible fibers. Application systems such as the bare fiber, the diffuse emitting fiber, the frosted sapphire tip and a newly developed circumferentially emitting fiber, the so-called ITT light guide, differ widely with respect to beam characteristics, power density at the fibertissue transition, maximum laser power, geometrical dimension, flexibility, adhesive properties and compatibility with MRI diagnostics and MRI therapy control. In vitro experiments as well as first results from animal trials and clinical experiments prove that the Nd:YAG laser and the new ITT light guide provide a simple and reliable technique for interstitial thermo therapy.
