We analyzed from the both clinical and pathological viewpoints. 206 cases operated on for early gastric cancer during the period between 1975 and 1987. The incidence of lympn node metastasis was 4% from m cancer and 11.9% from sm cancer. Lymph node metastasis occurred in differentiated type and elevated types. In clinicopathological analysis, we considered that limited gastrectomy for early gastric cancer was indicated n type I and type IIa tumors less than 2 cm in diameter. IIc without a co-existing ulcer was also indicated. Endoscopic ultrasonography was used to determine the depth of early gastric cancerous invasion. The correct diagnostic rate was 100% for IIc without co-existing ulcer and elevated type of m cancer less than 2 cm in diameter. The rate for IIc type sm cancer was 71.4%. We concluded that eadoscopic ultrasonography pattern analysis was useful for diagnosing the depth of cancerous invasion in limited gastrectomy for early gastric cancer.
