Paper Abstract

This study compared the laser tissue effect of the Dornier FiberTomeTM system, the conventional Nd:YAG and the KTP laser on the stomach and liver. The cutting capabilities, thermal effects of the laser systems, as well as their dependence on power output and tissue type, were evaluated. A motorized fiber holder to maintain constant conditions (cutting speed fiber angle, and pressure) was developed. The results show that the cutting depth and cutting width are inversely proportional to the output level. The thermal damage remained constant as the output increased. Use of the FiberTomeTM system appears to be more advantageous than the conventional Nd:YAG laser in pigmented tissues, in the range of the parameters tested.
