Conference paper


Surgery is the best available choice of treatment for the malignant gastrointestinal tumor. But in later stages of advanced obstructive cancer of the G-I tract most individuals are not good candidates for operation or irradiation. Implantation of endoprotheses for the stenotic G-I tumor has limiting factors that result in adverse conditions for some patients. Laser therapy is a palliative treatment in a lumen narrowing by G-I cancer by correcting obstruction and improving the patient’s nutrition. Nd:YAG laser and electrocoagulation can both arrest G-I bleeding in the earlier years.(1–5) In 1982, Fleischer first tried using the Nd:YAG laser to treat 5 patients with advanced obstructive esophageal cancer and their dysphagia was significantly improved.(6) A 63% effective palliative rate for the malignant tumor by Nd:YAG laser therapy was reported by Kobayashi in 1983.(7)
