Efficacy of the Altemeier Procedure for Rectal Prolapse

Akiharu Kurihara, Yasuyuki Miura, Satoru Kagami, Tomoaki Kaneko et autres

目的：直腸脱に対するAltemeier法の有効性と安全性について検討した．方法：2009年12月から2024年12月までにAltemeier法を施行した120例を後方視的に解析した．また同時期に施行した直腸固定術（Rectopexy）と比較検討した．結果：平均年齢は81歳，女性は117例であった．Clavien-Dindo分類II以上の合併症はAltemeier法で4.2％，Rectopexyで6.8％に発生した．再発率はAltemeier法で38％，Rectopexyで6.8％であり，再度Altemeier法を受けた5例全員が再発した．再発のリスク因子は女性，手術時間，直腸脱の手術歴であった．結論：Altemeier法は低侵襲かつ安全な術式であるが，Rectopexyと比較して再発率が高い点が問題である．再発例には経腹手術の適応を考慮すべきである．
