Endoscopic Ultrasonography Used to Evaluate Indcations for Limited Gastrectomy in Early Gastric Carcinoma

We analyzed from the both clinical and pathological viewpoints. 206 cases operated on for early gastric cancerduring 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 clinicopathologicalanalysis, we considered that limited gastrectomy for early gastric cancer was indicated n type I and type IIa tumorsless than 2 cm in diameter. IIc without a co-existing ulcer was also indicated. Endoscopic ultrasonography was usedto determine the depth of early gastric cancerous invasion. The correct diagnostic rate was 100% for IIc withoutco-existing ulcer and elevated type of m cancer less than 2 cm in diameter. The rate for IIc type sm cancer was71.4%. We concluded that eadoscopic ultrasonography pattern analysis was useful for diagnosingthe depth ofcancerous invasion in limited gastrectomy for early gastric cancer.
