Learn the step-by-step technique of the Extra Corporeal Dundee Jamming Knot in this detailed video. Perfect for surgeons, medical students, and anyone interested in advanced surgical suturing techniques. Watch this video to master the knot and improve your surgical skills.

The ability to suture in laparoscopic surgery is necessary less frequently than in conventional surgery, yet this ability is essential in certain critical situations, such as providing tissue support, maintaining tissue closure, and in creating certain surgical anastomoses. Although the principles of suturing and tying knots in endoscopic surgery are identical to those in conventional surgery, major modifications in technique are necessary as a result Extra Corporeal Dundee Jamming Knot is very useful. It can be prepared outside and then it can be introduced inside the abdomen to use as continuous suturing. The termination of this knot is by Aberdeen termination.

Secure knot tying is a fundamental skill in minimally invasive surgery. Among the various extracorporeal knotting techniques, the Extra Corporeal Dundee Jamming Knot is widely used due to its simplicity, reliability, and effectiveness in laparoscopic procedures. This knot allows surgeons to maintain consistent tension while ensuring a firm and secure ligature, making it especially useful in confined operative fields.

What Is the Extra Corporeal Dundee Jamming Knot?

The Extra Corporeal Dundee Jamming Knot is a sliding extracorporeal knot that is tied outside the body and then advanced into the operative site using a knot pusher. Once positioned, the knot is “jammed” securely against the tissue, preventing slippage. Its design provides excellent holding strength while minimizing tissue trauma.

Indications and Clinical Applications

This knot is commonly employed in a variety of laparoscopic and minimally invasive procedures, including:

• Ligation of vessels and pedicles

• Securing sutures during laparoscopic hernia repair

• Gynecological surgeries such as hysterectomy and ovarian cystectomy

• General surgical procedures requiring controlled tension

• Urological and pediatric laparoscopic surgeries

Step-by-Step Technique

1. Suture Placement – Pass the suture through the target tissue using laparoscopic instruments.

2. Exteriorization – Bring both ends of the suture outside the trocar.

3. Knot Formation – Create the Dundee knot extracorporeally with appropriate loops and throws.

4. Sliding the Knot – Advance the knot into the abdomen using a knot pusher.

5. Jamming – Apply steady tension to seat and jam the knot firmly against the tissue.

6. Securing – Add additional half-hitches if required for extra security.

Advantages of the Dundee Jamming Knot

• Provides strong and reliable knot security

• Easy to learn and reproduce

• Maintains consistent tension during knot advancement

• Suitable for beginners and advanced laparoscopic surgeons

• Reduces operative time compared to intracorporeal knotting

Common Mistakes and Tips

• Ensure equal tension on both suture limbs while sliding the knot

• Avoid excessive force to prevent tissue damage

• Use a proper knot pusher for accurate placement

• Practice the technique in dry lab or box trainers before clinical use

Educational Importance

The Extra Corporeal Dundee Jamming Knot is an essential part of laparoscopic skill training programs. Mastery of this knot enhances a surgeon’s confidence and efficiency, especially in situations where intracorporeal suturing may be challenging.

Conclusion

The Extra Corporeal Dundee Jamming Knot remains a cornerstone technique in minimally invasive surgery. Its strength, simplicity, and versatility make it an invaluable tool for laparoscopic surgeons across multiple specialties. Regular practice and proper technique ensure optimal surgical outcomes and patient safety.
