Video of Extra Corporeal Dundee Jamming Knot: A Reliable Technique in Laparoscopic Suturing
In this video, we will discuss that In laparoscopic surgery, secure knot tying is fundamental to ensuring the integrity of closures, especially when dealing with hollow organs, bleeding pedicles, or mesh fixation. The Extra Corporeal Dundee Jamming Knot is one such reliable suturing technique that provides strong, secure, and slip-resistant ligation. In this educational video titled "Extra Corporeal Dundee Jamming Knot: A Reliable Technique in Laparoscopic Suturing," we demonstrate the step-by-step formation, application, and clinical relevance of this knot in various laparoscopic procedures.
What Is the Dundee Jamming Knot?
The Dundee Jamming Knot is an extracorporeal knot—formed outside the body—that is pushed into the abdominal cavity using a knot pusher. It is a modified slip knot with a locking mechanism that prevents loosening under tension. The design of this knot makes it especially useful in situations where tissue approximation must be tight and secure, and where intracorporeal knotting may be challenging due to space constraints or limited visibility.
Key Steps Demonstrated in the Video
Creating the Base Loop
The knot starts with a simple overhand loop followed by additional locking throws, strategically placed to prevent the knot from unraveling once tightened.
Locking Configuration
The knot includes 2–3 half hitches with alternating directions, converting the slip knot into a jamming, secure configuration that stays in place when pushed down.
Extracorporeal Application and Delivery
Once the knot is formed, it is loaded onto a knot pusher and advanced into the peritoneal cavity under direct laparoscopic vision to secure the targeted structure.
Tension and Tightening
The final pull locks the knot into place with minimal risk of slippage, ideal for ligating vascular pedicles or closing enterotomies.
Clinical Applications of the Dundee Jamming Knot
Appendiceal stump closure
Tubal ligation in sterilization procedures
Hernia sac ligation during TAPP or TEP repair
Bowel or bladder defect approximation
Ligation of cystic duct or artery in cholecystectomy (when clips are not preferred)
Advantages of the Technique
Simple to learn and teach
Time-efficient compared to complex intracorporeal techniques
Strong knot security with minimal slippage
Versatile application across a wide range of laparoscopic surgeries
Useful for surgeons in training or in low-resource settings where staplers or advanced energy devices may be unavailable
Conclusion
The Extra Corporeal Dundee Jamming Knot remains a cornerstone of laparoscopic suturing—balancing efficiency, safety, and reliability. Its ease of formation and dependable hold make it an essential skill for every laparoscopic surgeon. This video offers a clear, practical demonstration to help viewers master the technique and apply it confidently in clinical practice.
