The 4-S modification of the Roeder knot may be tied laparoscopically as a single-throw knot.
It is tied by adding a fourth wrap around the suture loop and securing the loop in place with a square knot rather than a single half-hitch.
We have used this knot in laparoscopic surgeries for more than 2 years and have not observed knot slippage.
This modification results in a knot comparable in strength to the strongest laparoscopic multiple-throw square knots.
Roeder结的4-S改良法可在腹腔镜下打成单结。
通过在缝线环上增加第四次缠绕并用方结而非单半结将环固定到位来打结。
我们在腹腔镜手术中使用这种结已超过2年，未观察到结滑脱。
这种改良产生的结在强度上与最强的腹腔镜多结方结相当。
