Nd : YAG laser has been used in the treatment of colorectal cancer since the 80 s. The first results were published in 1980 by Frank and company/li. Authors have been nade with the technique since 1986,when the first experinents with laser started/2/- In the 1986 the laser was worked on wavelenghts of 106 urn and 1319 unThe goal of these experiments was to setup an optimal usage of both wavelenghts, and to establish a safe schedule of outputs with the minimum of perforations of intestines- Since January 1988 our clinic has been using the laser in the therapeutic program. In clinical treatments laser with the wavelenght of 1064 urn and the power of 40 - 50 V is used. Only in rare cases we use the power over 50 V The ratio of energy for one treatment depends only on the clinical effect, there are no other limits In the first period of our clinical practice, from 1988 to 1991, all the laser treatments were held under a short-tine anestezy Our patients were hospitalized for 2 or 3 days- For the actual treatment.s, we used a rigid endoscopic technique and also a flexible technique (coloskop)- We preferred the flexible technique definitely Since January 1991 we have been practicing almost all treatments in ambulant schedule without general anestezia Only in the cases where treatments reach under linea dentata, we choose short-term inhale anestezia. The patients are hospitalized for one day In the actual treatments we take advantages of the Nd:YAG laser- We try to evaporize the most of the tumor masses during great hemostazis The hemostazis is defined by the zone of coagulation-
