経腹的後腹膜リンパ節吸引生検法

Abstract

泌尿性器腫瘍の21例に経皮的後腹膜リンパ節吸引生検をおこない, 20例に充分な生検材料を得た.リンパ管造影で転移を診断できたのは1例のみであったが, リンパ節吸引生検により, 先の例を含め6例にリンパ節転移を証明しえた.後腹膜リンパ節吸引生検法は前立腺癌のstaging lymph node dissectionにかわりうる検査法であり, また, 膀胱癌に対する手術方法の決定に重要な検査法となる

Percutaneous fine needle aspiration of retroperitoneal pelvic and abdominal lymph nodes was done in 21 patients with clinically localized bladder, prostate, or penile cancers. A diagnosis of metastases to regional lymph nodes was detected by this method in 6 patients, but only one case could be diagnosed by bipedal lymphography. Positive aspiration results may spare the patient with prostatic or bladder cancer an unnecessary radical operation. This method also enables the detection of micrometastasis of lymph node which can not be detected by lymphography. No complications were seen in this series.
