Abstract

The Roeder knot is commonly used during laparoscopic suturing because it may be tied extracorporeally and slid down to the target tissue with a single pass of a knot pusher. However, it is significantly weaker than extracorporeally tied knots with several throws. We compared the usual Roeder knot to one that was modified by adding a fourth loop around the standing end of the suture and a second half-hitch to the completed knot. The modified knot (26.6 newtons ± 15.3) was significantly stronger (p < 0.05) than the standard Roeder knot (18.0 newtons ± 12.1). If a single-pass extracorporeal knot is to be used, we recommend a modified Roeder knot when ligating pedicles at laparoscopy.
