Roedner's knot is used for which structures?

• A. Blood vessels, appendix, fallopian tube, cystic duct
• B. Esophagus
• C. Ureter
• D. Larynx

Answer: (A)

Roeder’s knot is a sliding, self-tightening knot used in laparoscopic suturing to secure ligatures around tissue pedicles. It holds firmly as the free end is pulled, making it ideal for quickly and reliably tying off structures you plan to divide. In practice, this knot is commonly used to ligate vascular pedicles and tubular structures encountered in laparoscopy, such as blood vessels, the base of the appendix, the fallopian tube, and the cystic duct. These are the kinds of pedicles and ducts that require a secure, compact ligature in the limited laparoscopic field. Other structures like the esophagus or larynx aren’t typical targets for this knot in standard laparoscopic practice, and the ureter is usually managed with different techniques depending on the procedure.
