Video of Extra Corporeal Meltzer's Knot: A Time-Tested Technique in Laparoscopic Ligature
In this video, we will discuss that In the realm of minimal access surgery, the ability to secure tissues safely and efficiently is fundamental. Among the array of suturing techniques available, the Extra Corporeal Meltzer's Knot stands out as a reliable, easy-to-learn, and secure method of extracorporeal ligation. In this video titled "Extra Corporeal Meltzer's Knot: A Time-Tested Technique in Laparoscopic Ligature," we present a detailed, step-by-step demonstration of this classic knot used extensively in laparoscopic procedures around the world.
What is the Meltzer's Knot?
The Meltzer’s Knot is an extracorporeal slip knot designed to be tied outside the abdomen and delivered to the operative site using a knot pusher. Its core advantage lies in its ability to slide easily through a 5mm or 10mm port and lock securely upon final tightening. It is constructed with a series of loops and locking throws that, when properly formed, prevent slippage under tension, offering a firm and dependable ligature.
Key Features Demonstrated in the Video
Formation of the Knot
The knot begins with a base loop followed by a series of alternating half-hitches that create a sliding mechanism. This is followed by a locking configuration that jams the knot once secured at the target site.
Deployment with Knot Pusher
The knot is gently advanced through the laparoscopic port using a standard or dedicated knot pusher, with the surgeon maintaining control over tension to avoid premature locking.
Application on Tissue Structures
The video demonstrates the knot being deployed to ligate a tubular structure such as the appendicular base, fallopian tube, or mesenteric pedicle, showcasing its practical utility.
Clinical Applications of Meltzer's Knot
Laparoscopic appendectomy for base ligation
Tubal ligation during laparoscopic sterilization
Ligation of mesenteric or vascular pedicles
Closure of enterotomies in selected cases
Hernia sac ligation or intracorporeal anchoring where staplers are not used
Advantages of the Extra Corporeal Meltzer’s Knot
Quick and simple to learn, ideal for surgical trainees
Secure and reliable, with minimal risk of unraveling
Suitable for resource-limited settings where staplers or clips may not be available
Provides strong hemostasis and closure
Easily adapted to a wide range of laparoscopic procedures
Conclusion
The Extra Corporeal Meltzer’s Knot is a trusted, time-tested technique that every laparoscopic surgeon should master. Its simplicity, effectiveness, and adaptability make it a cornerstone in laparoscopic knotting, especially when intracorporeal options are limited. This video is a complete visual guide to understanding and applying the Meltzer’s Knot with confidence in clinical practice.
