RESUMO
Twenty three cases of colorectal carcinoma with partial or complete obstruction were managed by laser ablation of tumour tissue. There were 14 males and 9 females with a mean age of 63 years (30-87). Nineteen cases (82.6%) were in the rectosigmoid while two cases each were in the anal canal and descending colon. Fifteen (65.2%) were proliferative growths and the remaining (8, 34.7%) were circumferential growths. Prior dilatation under fluoroscopic control was done where required. Lumen was achieved in a single sitting in 14 (60.8%) cases, while in the others two to five sittings were required. None of the patients required colostomy. Thirteen (56.5%) of these patients have died during the follow up period, lasting from 4 to 27 months (mean 10.4 months). There were no major complications related to the procedure.
