We have experienced 61 early gastric cancer cases (inpatients, 64 lesions) using endoscopic YAG laser, I type: 1.0 cases, IIa type: 32 cases, IIc type: 21 cases,IIa+IIc type: lease. All patients have not taken surgical Operation due to some kinds of reason.
We could observed 23 cases of no relapse over 5 years.
Small size (below 2cm) elevated losion (IIa type) is good indication for laser therapy. IIc type of size below 1cm and no ulces is treated completedly. Histologically well-differentiated adenocarcinoma is good indicaked.
Laser therapy combined another endoscopic therapy is effective for improving the quality of life in patients with nonresectable advanced cancer of the G. I tract. We will describe several advantages of laser ballon for clinical cases.
