From November 1, 1992 to January 31, 1997, we treated 189 pts: 113 males and 76 females, of mean age 67 yrs. 148 pts were affected with colo-rectal cancer and 41 pts with extensive carpet benign tumors. Tumor location was: rectum in 115 pts, recto-sigmoid joint in 31 pts, colo-rectal anastomosis in 25 pts, sigmoid colon in 15 pts, descending colon in 2 pts and cecum in 1 pt. 26 pts were treated with diathermo-therapy, 15 pts with dilatation, 12 pts with radiotherapy, 5 pts with chemotherapy, 1 pt with chemotherapy and radiotherapy. Yag-laser palliation gave good results in 90% (170 - 189) with an average survival of 24 weeks; there were complications due to the treatment in due pts (1%) without hospital mortality.
