Abstract

症例は55歳,女性.検診にて便潜血反応陽性を指摘され,本院を受診.注腸,大腸内視鏡検査にて,直腸S状部に9×7mm大の中央に陥凹を伴う広基型の隆起型病変を認め,内視鏡的切除術が施行された.その病理組織学的検査では切除断端にまで癌細胞が認められ,追加腸切除を施行した.切除腸管の病理組織学的検査にて癌の壁深達度はssで,リンパ節にも転移を認めた. 10mm未満の大腸進行癌の本邦報告例は10例であり,大腸の小病変に対するポリペクトミーには慎重である必要があると思われた.

A 55-year-old woman was seen at the hospital because her stools were positive for occult blood at medical checkup. Barium enema study revealed a polyp about 10mm in diameter in the rectosigmoid. Colonoscopy demonstrated a 9× 7mm sessile poly with central depression at the same portion and a polypectomy was carried out. Since histological examination of the polypectomy specimen showed adenocarcinoma with positive polypectomized stump, high anterior resection was performed. Resected specimen revealed moderately differentiated adenocarcinoma which remained in the colonic wall and invaded the subserosal layer with vessel invasion and lymph node metastasis. Eleven cases of small advanced colorectal cancer under 10mm in size have been reported in Japan including our case. We should take a careful attitude to apply the polypectomy for small colorectal lesions.
