直腸カルチノイドの診断と治療

The Diagnosis and Treatment of Rectal Carcinoid

要旨　1957年より1989年4月までの32年4か月間に癌研付属病院で経験した41例の直腸カルチノイドにつき検討した．症状は排便時の出血が最も多く，腹痛がこれに次いだが，カルチノイド症候群を随伴するものはなかった．X線検査では，亜有茎性～無茎性の円形ないし楕円形の隆起性病変として診断された．大腸内視鏡では，淡黄～黄色の色調の無茎性～亜有茎性の隆起性病変として認められた．径の増大と共に中心陥凹ないし潰瘍を伴った．

　Forty-one cases with rectal carcinoid tumor were reviewed regarding its diagnosis and treatment. All cases were experienced at the Cancer Institute Hospital in a period of 32 years and 4 months. Anal bleeding was the most frequently encountered symptom followed by abdominal pain. There was no case with carcinoid syndrome. Radiographically the majority were recognized as having a subpedunculated or sessile polypoid lesion, round or oval in shape. Endoscopically, these subpedunculated or sessile polypoid lesions had yellowish to slightly yellowish hue. The frequency of observing a central depression was positively correlated with the size of carcinoid tumor.
