[The changes in the treatment of early gastric cancer--endoscopic mucosal resection and limited (nerve preserving) operation].
We have been trying to perform endoscopic mucosal resection (ER) since 1987, and limited operation since 1985 (nerve preserving operation since 1991) for early gastric cancer. 205 patients were performed ER from 1978 to 1990, 78 patients were performed limited operation from 1985 to 1993. We perform ER according to the indication as follows: 1) differentiated IIa type, size approximately 2 cm, 2) differentiated IIc type, size approximately 1cm, Ul(-), 3) undifferentiated IIc type, size approximately 5mm, Ul(-). And the indication of limited operation is the patients with intramucosal cancer and tumor size approximately 2cm. Up to date, we have never experienced recurrence of these patients undergone ER or limited operation. As to QOL, these therapy will be expected to improve QOL of early gastric cancer patients, especially per os and body weight loss after surgery.
