This video demonstrates the Dundee Jamming Knot, a reliable and secure surgical knot widely used in laparoscopic and open procedures. In this educational video, you will learn the step-by-step technique of creating the Dundee Jamming Knot, its clinical importance, and tips to ensure maximum knot security during surgery. Watch this video to enhance your surgical knot-tying skills and improve operative efficiency.

Dundee Jamming knot is very good starter knot which is prepared outside the abdomen and then dropped inside the abdomen through one of the port to tie intracorporeal continuous suturing.

The Dundee Jamming Knot is an important surgical knot widely used in laparoscopic and minimally invasive surgery. It is primarily used as a starter knot for continuous suturing, especially when surgeons want to begin suturing efficiently without first tying a complex intracorporeal knot. With the advancement of laparoscopic and robotic surgery, specialized knot-tying techniques like the Dundee Jamming Knot have become essential for safe and effective tissue approximation.

The Dundee Jamming Knot is usually formed outside the body (extracorporeally) and then introduced into the abdominal cavity through a laparoscopic port. After the first tissue bite is taken, the suture is passed through the loop of the knot and tightened, allowing the knot to “jam” against the tissue and secure the starting point of the suture line. This design helps the knot lock firmly and maintain tension, which is essential in laparoscopic procedures where tactile feedback is limited.

Structurally, the knot is created using a slipping loop with an additional loop formation, often resembling a figure-of-eight configuration. The tail is passed through loops and tightened to form a locking structure. Once tightened and positioned properly, additional knots or hitches can be applied for extra security if required.

One of the main advantages of the Dundee Jamming Knot is that it simplifies the start of continuous suturing. Surgeons often prefer it because it allows smooth introduction into the operative field and provides reliable fixation once tension is applied. It is commonly used in laparoscopic tissue closure, anastomosis suturing, and other procedures where continuous suturing is required. In some cases, it may also be used for interrupted sutures, although extra hitches are recommended to prevent slippage.

In modern laparoscopic practice, the Dundee Jamming Knot is considered one of several intracorporeal knotting techniques, alongside surgeon’s knot, square knot, tumble square knot, and Aberdeen termination knot. Mastery of these knots is crucial because laparoscopic knot tying is technically challenging due to limited space and reduced tactile sensation.

In conclusion, the Dundee Jamming Knot plays a significant role in minimally invasive surgery by providing a reliable and efficient way to start continuous suturing. Its extracorporeal preparation, secure locking mechanism, and ease of introduction into the operative field make it a valuable technique for laparoscopic surgeons. As surgical technology continues to evolve, knowledge of such specialized knots remains fundamental to achieving safe surgical outcomes and improving patient care.
