Video of Extra Corporeal Roeder's Knot: A Classic Technique in Laparoscopic Ligature
In this video, we will discuss that In the practice of laparoscopic surgery, secure knot-tying is a cornerstone for ensuring reliable tissue ligation and hemostasis. Among the earliest and most enduring extracorporeal knotting methods is the Roeder's Knot, a technique that has stood the test of time due to its simplicity, strength, and reliability. This video, titled "Extra Corporeal Roeder's Knot: A Classic Technique in Laparoscopic Ligature," presents a step-by-step demonstration of this essential surgical skill, emphasizing its practical applications and effectiveness in various laparoscopic procedures.
What Is the Roeder's Knot?
The Roeder’s Knot is an extracorporeal sliding and locking knot created outside the body and introduced into the abdominal cavity using a knot pusher. It consists of a combination of a base knot (typically a surgeon’s knot) followed by multiple locking throws that jam the knot securely upon tightening. The key advantage of the Roeder’s Knot lies in its ability to slide smoothly during deployment and lock firmly at the site, making it ideal for use on tubular or vascular structures.
Key Techniques Demonstrated in the Video
Knot Construction
The Roeder's Knot is built using one initial loop (a slip component), followed by two or more locking half-hitches in alternating directions. This configuration provides both mobility during placement and secure locking once positioned.
Deployment Using a Knot Pusher
After construction, the knot is loaded onto a standard laparoscopic knot pusher and guided through the trocar to the site of ligation. The video clearly shows the technique of tightening and locking the knot around the structure.
Practical Application Examples
Demonstrated on structures such as the appendix base, fallopian tubes, and cystic ducts, the video provides real-time examples of how the Roeder’s Knot performs in routine laparoscopic surgeries.
Common Applications in Laparoscopic Surgery
Laparoscopic appendectomy – securing the base of the appendix
Tubal ligation – occluding the fallopian tubes in sterilization
Cholecystectomy – ligating the cystic duct or artery
Small bowel resection – closing mesenteric vessels
Hernia repair – ligating hernia sacs or redundant tissue
Advantages of the Roeder’s Knot
Quick and easy to tie, especially for beginners
Secure and reliable, even under significant tension
Cost-effective, eliminating the need for expensive staplers or clips
Minimally invasive, deliverable through 5mm or 10mm ports
Versatile, applicable across a broad range of laparoscopic procedures
Conclusion
The Extra Corporeal Roeder’s Knot remains a classic, essential technique in the laparoscopic surgeon’s repertoire. Its dependable locking mechanism, ease of construction, and adaptability make it an ideal choice for safe and effective extracorporeal ligation. Whether in a high-tech OR or a resource-limited setting, mastering this knot enhances surgical confidence and improves procedural outcomes.
