現在広く普及している内視鏡下体内結紮法としてsquare knotがあるが,さらに迅速簡便に男結びが可能となる新しい結紮法を提案する.本法は既知のslip knotからヒントを得た方法で,対称的な糸のループを形成しておき,その中に糸の一端を通すことで,1回の操作にて迅速簡便に男結びが可能となる結紮法である.当院の5人の外科医の結紮所要時間は,square knotが41.7±9.41秒(平均±SD)に対し,新法が26.2±4.60秒(同)と有意な所要時間の短縮を認めた.基本であるsquare knotを習得したうえで新しい方法を身に付け,結紮のバリエーションを増やすことは有用であり,また臨床応用上も有用な方法であると考える.
The square knot, which is advocated by Zoltan Szabo, is a popular method for intracorporeal knot tying in endoscopic surgery. We propose a new knot tying method. We invented this method from the slip knot. The tail of the thread is passed through a symmetrical loop, and an opposite half knot is made rapidly and easily in one action. The mean knot tying time of five surgeons in our hospital was 41.7 sec. (square knot)and 26.2 sec. (new method). We were able to shorten the knot tying time by using this method. In addition to mastering the basic square knot, it is valuable to learn new method. Moreover, this method is useful in clinical application.
