Abstract
Endoscopic mucosectomy was done for sixty-six lesions of early gastric cancer which were diagnosed well to moderately-differentiated adenocarcinoma during a period from 1999 to 2002 at Ibaraki Prefectural Central Hospital&Cancer Center. The depth of the cancerous invasion in the gastric wall limited to the mucosa and the lesion was not accompanied with fold convergence and ulcer. A single fragment mucosectomy was carried out in 70% of the lesions of 21 to 30mm diameter. But it was performed in 72.2% of the lesions smaller than 10mm diameter, 60% for the lesions 11 to 20mm diameter which was lower than the result of EAM (endoscpoic aspiration mucosectomy) (84.3% Ref.1) .
Endoscopic mucosectomy using insulation-tipped diathermic knife for early gastric cancer was recommendable especially for the lesion larger than 21mm diameter. EAM is rather thought to be adequate for the lesion less than 20mm diameter. Recently we use hyaluronic acid sodium for lifting submucosa, which we hope, makes the result of a single fragment mucosectomy improved.
