随着诊断工具的改善,现在大多数胃癌治疗前可获正确的诊断,然而对直径小于或等于1cm的早期胃癌,诊断仍有困难。本文对28例病人中32个直径等于或小于1cm的早期胃癌的诊断特征进行探讨。“微癌”系指最大直径等于或小于5 mm的早期胃癌。“小胃癌”乃指直径在6～10mm之间的早期胃癌。材料和方法;本文以日本1972～1983年224例胃切除标本中28例直径小于1cm的早期胃癌为分析材料。术前曾经上消化道钡透(包括加压法和双重对比法),常规使用侧视,必要时也用前视胃镜检查。有
With the improvement of diagnostic tools, most gastric cancers can now be diagnosed correctly before treatment. However, diagnosis of early gastric cancer with a diameter of 1 cm or less is still difficult. This article discusses the diagnostic characteristics of 32 early-stage gastric cancers with a diameter equal to or less than 1 cm in 28 patients. “Micro-cancer” refers to early gastric cancer with a maximum diameter of 5 mm or less. “Small gastric cancer” refers to early gastric cancer with a diameter of 6-10 mm. Materials and methods; 28 cases of early gastric cancer with a diameter of less than 1 cm in 224 gastrectomy specimens from 1972 to 1983 in Japan were used as the analysis materials. Before the operation, the upper digestive tract was penetrated (including the pressurization method and the double contrast method), and the side view was conventionally used. If necessary, front view gastroscopy was also used. Have
