[Endoscopic treatment of early gastric cancer with laser and laserthermia using Nd : YAG laser].

As a therapeutic modality for early gastric cancer, endoscopic laser treatment is indicated in cases where the tumor is an intramucosal carcinoma, the macroscopic type is either I, IIa, or IIc(Ul(-)), and the diameter of the tumor is less than 10 mm. Type I tumors with less than 15 mm diameter and type IIa tumors with less than 20 mm diameter can be included in this indication. Depressed lesions should be treated carefully. Endoscopic laser treatment may be considered for patients who are not candidates for surgery or who refuse surgery.
