  • Abstract
  • Look Inside

 Eighty four early gastric cancers were treated with endoscopic Nd-YAG laser irradiation therapy. Macroscopic type Ⅰ and Ⅱa less than 2.0 cm in size and type Ⅱc with Ul(-) less than 1.0 cm in size mucosal cancers are considered to be absolute indications for endoscopic therapy because of the minuscule possibility of lymph node metastasis.

 Absolutely indicated 40 lesions were treated with endoscopic laser irradiation and 38 of them showed no relapse of cancer over 6 months' period. Ralatively indicated 12 superficial elevated type lesions were also treated with laser therapy and 11 of them had no recurrence of cancer after more than 6 months'duration. However, laser treatment had poor efficacy in dealing with superficial depressed type lesions with submucosal invasion.

 Therefore it is suggested that endoscopic laser therapy could be highly effective, if it would be applied on absolutely indicated and protruding type lesions.
