作者将最大直径<5mm的胃癌称为微小胃癌。对1959～1981年在大阪成人疾病中心手术治疗的54例55个微小胃癌加以分析。15例为孤立性微小癌,39例为伴有较大癌的微小癌。前者称为“孤立性病例”,后者称为“多发性病例”。多发性病例的微小胃癌常在胃切除的标本中由组织学发现。根据内窥镜所见,将癌分为四型:(1)凹陷型伴皱襞聚集。(2)凹陷型无皱襞聚集。(3)扁平型。(4)凸起型,进而分析每一类型在内窥镜视诊及组织细胞学检查中的诊断准
The authors described gastric cancer with a maximum diameter of less than 5 mm as a tiny gastric cancer. We analyzed 55 small gastric cancers in 54 cases surgically treated at the Osaka Adult Disease Center from 1959 to 1981. 15 cases were isolated microcarcinomas and 39 cases were microcarcinomas with larger cancers. The former is called an “isolated case” and the latter is called a “multiple case.” Microscopic gastric cancers in multiple cases are often histologically discovered in gastrectomy specimens. According to the endoscopic findings, the cancers are divided into four types: (1) Indented corrugations gather together. (2) Indented type without wrinkle gathers. (3) Flat type. (4) Protrusion type, and analyze the diagnostic criteria of each type in endoscopic examination and histological examination
