作者研究了胃手术后病人的胃癌发生率,并分析了作为一种恶变前病变的上皮细胞生长异常与手术的关系。对71例1964年前因良性消化性溃疡而行胃手术的病人作纤维内窥镜检查,同时多处刷取脱落细胞作细胞学检查,5～10％的病例并活检作组织学检查。71例年龄为50～75岁,首次手术分别在15～35年前。 The authors studied the incidence of gastric cancer in patients after gastric surgery and analyzed the relationship between abnormal growth of epithelial cells as a premalignant lesion and surgery. 71 cases of patients undergoing gastrectomy due to benign peptic ulcer before 1964 were subjected to fiber endoscopy. At the same time, exfoliated cells were brushed at multiple sites for cytological examination, and 5 to 10% of cases were examined by biopsy for histological examination. 71 cases were 50 to 75 years old and the first operation was 15 to 35 years ago.
