This video demonstrate For the surgeon to develop the same level of proficiency and dexterity in the endoscopic environment as he may possess in open surgery is not a simple matter. The use of proper Mishra's Knot, are essential.  Participating in an in-depth, systematic training program in a laboratory setting is essential before applying endoscopic Mishra's Knot techniques to humans. Successful acquisition of these Mishra's Knot skill requires that the surgeon be motivated to succeed and willing to invest the time and effort necessary to do so.

Laparoscopic appendicectomy is one of the most commonly performed minimally invasive surgical procedures for the treatment of acute appendicitis. Over the years, technological and technical innovations have improved the safety, affordability, and efficiency of this operation. One such important innovation is Mishra’s Knot, developed and popularized by Prof. Dr. R. K. Mishra at World Laparoscopy Hospital. This technique represents a major step toward cost-effective and reliable appendicular stump closure, especially in resource-limited settings.

Laparoscopic appendicectomy involves removal of the inflamed appendix using small incisions and a camera-guided surgical system. Typically, three ports are used: an umbilical camera port and two working ports in the suprapubic and left lower abdomen. This minimally invasive approach offers several advantages such as reduced postoperative pain, faster recovery, lower infection rates, and better cosmetic outcomes.

During the procedure, the appendix is identified, the mesoappendix is divided, and the appendicular base is securely ligated before removing the specimen. Traditionally, surgeons have used endoloops, staplers, or clips for stump closure, but these methods can increase procedural cost and dependence on disposable devices.

Concept of Mishra’s Knot

Mishra’s Knot is a specially designed extracorporeal sliding knot used in laparoscopic surgery for secure ligation of structures such as the appendicular base. It combines the strength of a surgeon’s knot with the sliding ability of a slip knot, allowing it to be tightened precisely around the target tissue.

This knot is widely recognized for:

• Strong holding power with low risk of slippage

• Cost-effectiveness by avoiding staplers and endoloops

• Ease of learning and reproducibility

• Versatility across multiple laparoscopic procedures

The technique is especially valuable in training environments and hospitals where cost containment is essential.

Surgical Technique of Laparoscopic Appendicectomy Using Mishra’s Knot

The procedure follows standard laparoscopic appendectomy principles with modification in stump closure:

1. Port Placement

A three-port technique is generally used:

• Umbilical port for camera

• Left lower abdominal working port

• Suprapubic working port

2. Identification and Mobilization of Appendix

The appendix is located and gently mobilized. The mesoappendix is dissected carefully using energy devices while preserving surrounding bowel and cecum.

3. Division of Mesoappendix

The mesoappendix is divided close to the appendicular base to achieve hemostasis and clear visualization.

4. Application of Mishra’s Knot

• A long suture is passed around the appendicular base.

• The extracorporeal sliding Mishra’s Knot is prepared outside the body.

• The knot is introduced through the trocar and tightened securely at the base.

• Often, a second knot is added for additional safety.

5. Division and Removal of Appendix

The appendix is divided distal to the knot and removed using an endobag or trocar.

Role of World Laparoscopy Hospital

World Laparoscopy Hospital has played a major role in training surgeons worldwide in advanced laparoscopic techniques. Dr. R. K. Mishra has trained thousands of surgeons and gynecologists, promoting standardized, safe, and cost-effective minimal access surgery.

The hospital integrates theoretical teaching, simulation training, and live surgical exposure, helping surgeons master advanced skills such as extracorporeal knotting and laparoscopic suturing.

Advantages of Mishra’s Knot in Appendicectomy

1. Cost Reduction
   Eliminates need for expensive staplers or endoloops, making surgery affordable.

2. High Safety Profile
   Provides secure stump closure with low risk of slippage.

3. Technical Simplicity
   Can be learned easily by laparoscopic trainees and practicing surgeons.

4. Versatility
   Useful in multiple laparoscopic procedures including cholecystectomy and gynecologic surgeries.

Clinical Significance

In developing countries and high-volume surgical centers, cost plays a major role in patient access to care. Mishra’s Knot ensures that laparoscopic appendicectomy remains accessible without compromising surgical outcomes. Clinical experiences show comparable safety and effectiveness when compared with traditional device-based stump closure methods.

Conclusion

Laparoscopic appendicectomy using Mishra’s Knot represents a perfect blend of surgical innovation, safety, and affordability. Developed at World Laparoscopy Hospital, this technique demonstrates how surgical skill and innovation can reduce dependence on expensive disposable devices while maintaining excellent patient outcomes. As minimally invasive surgery continues to evolve, techniques like Mishra’s Knot will remain essential tools in the armamentarium of modern laparoscopic surgeons.
