The era of minimally invasive colorectal surgery has spurred the development of novel vessel-sealing and suture devices. This is in part due to the increased technical demand of performing minimally invasive surgery. Novel technology benefits the surgeon and at times reduces operating time, but does increase the cost of the operation. We describe the application of the extracorporeal Roeder knot in advanced laparoscopic and transanal procedures, which is a highly cost effective tool to add to the minimally invasive colorectal surgeon’s armamentarium.

The original Roeder’s knot was first described by Hans Albert Röder in 1931 [1], and it has a 1:3:1 formula—i.e. one half hitch, three winds, and one locking hitch. Its use in laparoscopic surgery was pioneered by Semm in 1981 when the knot was tied extracorporeally to ligate a vessel before transecting it [2]. This has also allowed approximation of tissue laparoscopically, used in earlier procedures such as laparoscopic...
