Weston clinch knot
The Weston knot was described by Dr. Peter Weston, a gynaecologist working in San Antonio in Texas, USA in 1991. The knot was not originally designed to be used at laparoscopy, but has been adopted by endoscopic surgeons as a very elegant slip knot.
This video shows a Weston knot being tied. Note the double half-hitches at the beginning but we only use a single half-hitch at the end for locking. As with the Roeder knot, we usually use vicryl sutures (2/0 to 1) depending on the tissue being sutured. However, as the Weston needs a longer lengths of suture outside the abdomen, we tend to use it less than the Roeder knot.
