腹腔鏡下に作成する結紮の工夫：slip knot 内無双

抄録

  To enhance one's skills in laparoscopic surgery, it is essential to learn and master the technique for tying laparoscopic knots. A knot that is made laparoscopically tends to loosen, and the loosened knot is known as an air knot. Once an air knot is formed, it is difficult to untie and then to re-tie it appropriately. The slip knot is an alternative and useful knot to prevent the formation of air knots. We present a newly developed knot tying technique, termed as the Uchimuso slip knot technique. The Uchimuso slip knot technique consists of two throws. The formation of the first single wrap throw is similar to that of the conventional instrument tie technique. The second throw is crucial to forming the new slip knot. This second single wrap throw is formed via a sequential movement by simulating a winning technique in sumo wrestling, known as Uchimuso. The Uchimuso slip knot is easy to learn and master, particularly in the case of laparoscopic intracorporeal knot tying.
