为探讨早期胃癌的诊断和治疗,通过对53例病人的诊断、术中肉眼观察和病理相对照,结果:气钡造影确诊率44.5％,纤维胃镜64.2％,活组织切片92.5％。淋巴结转移率大弯侧3.8％,小弯侧17％,大网膜无转移。认为早期胃癌诊断主要靠活组织切片,胄切除范围距癌缘2cm是安全的,淋巴结清扫粘膜内癌R_1,粘膜下癌R_2为宜,保留大网膜是可行的。 In order to explore the diagnosis and treatment of early gastric cancer, 53 cases were diagnosed, compared with macroscopic observation and pathology. Results: The rate of diagnosis was 44.5% for gastritis, 64.2% for gastroscopy, and 92.5% for biopsy. The rate of lymph node metastasis was 3.8% in the greater curvature side, 17% in the minor curvature side, and there was no metastasis in the greater omentum. It is believed that the diagnosis of early gastric cancer mainly depends on biopsy. The range of fistula resection is 2cm from the cancer margin. It is advisable to remove intramucosal cancer R_1 and submucosal cancer R_2. It is feasible to retain omentum.
