Roeder slip knot

The Roeder is the first and still one of the most well known slip knots used at laparoscopy. Originally, the Roeder knot was used by ENT surgeons for tonsillectomy. It was adapted for laparoscopy by the pioneering Professor Kurt Semm in the late 1970s.

This video shows a Roeder knot being tied. Note the double half-hitches at the beginning and the end, the latter being used to lock the suture. We usually use vicryl sutures (2/0 to 1) depending on the tissue being sutured.
