Video of Extra Corporeal Weston Knot: A Versatile and Secure Technique in Laparoscopic Surgery
In this video, we will discuss that In the field of laparoscopic surgery, knot security and ease of application are crucial, particularly in procedures requiring extracorporeal ligation. The Extra Corporeal Weston Knot is a time-tested technique known for its simplicity, strength, and minimal risk of slippage, making it a preferred method for ligating tubular and vascular structures. This video, titled "Extra Corporeal Weston Knot: A Versatile and Secure Technique in Laparoscopic Surgery," provides a comprehensive demonstration of this knot, offering viewers a valuable addition to their minimally invasive suturing skillset.
What is the Weston Knot?
The Weston Knot is an extracorporeal slip and lock knot designed to be tied outside the abdominal cavity and introduced intra-abdominally using a laparoscopic knot pusher. It is constructed with a sliding loop and locking throws, which allow for controlled tightening and firm closure once deployed over the target structure. This configuration makes it particularly effective in achieving tension-free, secure ligation with minimal technical complexity.
Video Highlights and Technical Breakdown
Step-by-Step Construction
The video shows how to form the Weston Knot with a long suture using a looped slip knot base followed by alternate locking half-hitches, which ensure that the knot locks effectively once tightened.
Controlled Deployment Using a Knot Pusher
The constructed knot is pushed into the peritoneal cavity via a 5mm or 10mm trocar, and guided over the target structure—such as the appendicular base, fallopian tube, or mesenteric pedicle.
Live Surgical Applications
Real-time examples demonstrate the Weston Knot’s versatility in appendectomy, tubal ligation, cholecystectomy, and bowel resections, proving its adaptability in both routine and complex laparoscopic cases.
Clinical Applications
Laparoscopic appendectomy – secure ligation of the appendicular stump
Tubal ligation – occlusion of fallopian tubes during sterilization
Cholecystectomy – ligating the cystic duct and artery
Bowel resection – mesenteric pedicle ligation
Hernia surgery – sac or vascular structure closure
Advantages of the Weston Knot
Simple and quick to learn and perform
Secure locking mechanism, reducing knot failure risk
Cost-effective, eliminating the need for clips or staplers
Ideal for low-resource environments
Compatible with standard laparoscopic ports (5mm or 10mm)
Conclusion
The Extra Corporeal Weston Knot is a versatile and dependable technique in laparoscopic surgery, offering strength, reliability, and ease of application. Its effectiveness in a wide range of procedures makes it an essential knot for any laparoscopic surgeon's repertoire. Whether you're a novice building your foundational skills or an experienced surgeon refining your technique, mastering the Weston Knot enhances both surgical safety and procedural efficiency.
