Roedner's knot is tied completely extrapoportally and then pushed down. It is used for which structures?

• A. Tied completely extrorporeally and then pushed down
• B. Tied in situ on tissue
• C. Tied with the needle in place
• D. Pushed through the tissue from inside

Answer: (A)

Roeder’s knot is an extracorporeal ligature technique used in laparoscopy. The knot is tied completely outside the abdomen and then pushed down into the operative field to secure the target structure. This approach provides a very secure ligature for pedicles or vessels that are large or awkward to tie from inside the cavity, such as ovarian or mesenteric pedicles and other sizable vascular pedicles. It isn’t formed in situ on tissue, isn’t tied with the needle in place, and isn’t pushed through tissue from inside—the knot is prepared outside and delivered down to encircle the structure.
