YAG Laser Treatment for Stenosis due to Advanced Cancer of Esophagus and Stomach-Non-contact and Contact Irradiation
We have treated stenosis due to advanced cancer of esophagus and stomach, which has no indication of surgery, with Nd-YAG laser irradiation, endoscopically. Recently, we have applied new type of endo- probe, attached at the tip of quartz fiber, made by ceramic. With this endoprobe, contact irradiation to a target lesion becomes possible. Results of non-contact and contact irradiation for treating stenosis due to advanced cancer of esophagus and stomach were evaluated.
