特集 前立腺全摘除術後の合併症―予防と対処
文献概要
要旨 リンパ節郭清を施行した前立腺全摘除術後の約半数の症例にリンパ囊腫が発生する。症候性リンパ囊腫では感染・疼痛を認め，再入院・外科的処置を要することが多い。リンパ囊腫の予測因子として，リンパ節郭清数，低分子ヘパリンの使用，年齢が挙げられている。リンパ囊腫の予防に関しては，リンパ節郭清を施行する症例の選別と緻密なリンパ管の結紮・シーリングが重要である。症候性リンパ囊腫を認めた場合は，CTを用いて診断して超音波ガイド下ドレナージを施行する。今後，拡大リンパ節郭清の導入によって，症候性リンパ囊腫の発生頻度の上昇が懸念される。リンパ囊腫の予防および対策はますます重要な問題となるであろう。
