小さなⅡc型早期胃癌症例―内視鏡所見と切除胃所見とを正確に対比させる方法としての点墨

A Case of Ⅱc Type Early Gastric Cancer with Special Reference to Ink Spot Method as a Means to Correlate Findings of Endoscopy with Those of Resected Stomach

　わが国における近年の胃診断学の進歩はいちじるしく，小さな病変でも発見できるようになった．早期胃癌の診断学的問題点は，大きさから言えば1.0cm以下の小さな病変の診断，型から言えばⅡb型の胃癌の診断に努力がなされている．それ故病巣が小さくなればなる程，また病変の凹凸が低くなればなる程，内視鏡所見と切除胃所見との正確な対比が要求される．

　今回，手術前の点墨により病巣の範囲に関して切除胃肉眼所見（新鮮および半固定），病理組織学的所見および内視鏡所見を正確に対比できた，小さなⅡc型早期胃癌を経験したので報告する．

　In a man 47 years of age a Ⅱc early gastric cancer was found on the anterior wall at the level of the angle, associated with depressed atypical epithelium. Before the operation ink spots had been made around the lesions, so that we were able to correlate exactly the findings of the resected stomach with those of endoscopy and histopathology. Our ink spot method proved to be of great help in endoscopy for the detection of Ⅱb or other small early gastric cancer.
