内容紹介
Summary
A 77-year-old man presented with biliary colic and was diagnosed with descending colon cancer and cholelithiasis. During the surgery, a mass was detected in the upper jejunum, located 5 cm from the Treitz ligament on the anal side. Open left hemicolectomy with partial jejunal resection was performed. The mass in the small intestine was diagnosed as solitary small intestinal metastasis of colon cancer through immunohistopathological examination. Isolated intestinal metastases of colorectal cancers are rare. Furthermore, synchronous metastases are rare among these cases. A previous study reported poor prognosis in patients with small intestinal metastasis; therefore, more studies on the small intestinal metastasis of colorectal cancer are necessary.
要旨
症例は77歳,男性。胆石発作の精査目的で当院紹介となったが,精査にて下行結腸癌を指摘され,手術を施行した。術中所見にてTreitz靭帯より5 cmの部位に空腸腫瘍が認められ,開腹下左半結腸切除術に加え空腸部分切除術を施行した。術後病理組織学的検査および免疫病理学的検査所見より空腸腫瘍は孤立性小腸転移と診断された。大腸癌の孤立性小腸転移は比較的まれであり,なかでも同時性転移は極めてまれである。小腸転移は予後不良と報告されており,治療法などさらなる症例の集積が必要である。
