This video demonstrate Cholecystectomy with Mishra's Knot at World Laparoscopy Hospital, Gurgaon. No other operation has been so profoundly affected by the advent of laparoscopy as cholecystectomy.

Laparoscopic cholecystectomy is the gold standard surgical procedure for the treatment of gallbladder diseases such as symptomatic gallstones and chronic cholecystitis. Over the years, advances in minimally invasive surgery have focused not only on reducing incision size but also on improving safety, efficiency, and cost-effectiveness. One such innovation is the use of Mishra’s Knot, a specialized extracorporeal knotting technique developed by Prof. Dr. R. K. Mishra and widely taught and practiced at World Laparoscopy Hospital.

Laparoscopic cholecystectomy involves removal of the gallbladder using small abdominal incisions and laparoscopic instruments. A crucial step during the surgery is secure ligation of the cystic duct and cystic artery to prevent bile leakage and hemorrhage. Traditionally, surgeons used metallic clips, staplers, or energy devices. However, these options can be expensive and occasionally associated with complications such as clip migration or slippage.

Mishra’s Knot provides an alternative by offering strong ligation using suture material rather than metallic clips. It is a self-sliding extracorporeal knot that combines the simplicity of extracorporeal knotting with the security of intracorporeal suturing.

What is Mishra’s Knot?

Mishra’s Knot is a modified extracorporeal sliding knot designed specifically for laparoscopic surgery. It is known for its strong holding capacity, resistance to slippage, and ability to be applied quickly and reliably. The knot is tied outside the body and then pushed inside the abdomen using a knot pusher to ligate structures such as ducts, vessels, or pedicles.

The knot configuration involves sequential hitches, winds, and half knots to create a stable structure that can secure tissues even up to relatively large diameters.

Role of Mishra’s Knot in Laparoscopic Cholecystectomy

During laparoscopic cholecystectomy, once the critical view of safety is achieved, the cystic duct and cystic artery must be ligated securely before division. Mishra’s Knot is applied around these structures and tightened using a knot pusher, ensuring firm closure.

Step-by-Step Surgical Application

1. Dissection and exposure of cystic duct and artery.

2. Formation of Mishra’s Knot extracorporeally.

3. Introduction of knot through trocar.

4. Placement around cystic duct or artery.

5. Sliding and tightening of knot using knot pusher.

6. Division of ligated structures followed by gallbladder removal.

This technique allows precise ligation with excellent control over tissue handling.

Clinical Advantages

1. Cost Effectiveness
Mishra’s Knot eliminates dependence on expensive disposable clips and staplers, making it highly beneficial in resource-limited settings.

2. Safety and Reliability
Studies have shown it to be feasible and safe with low postoperative complication rates such as bile leak or infection.

3. Strong Ligation and Reduced Slippage
The sliding-locking mechanism provides superior holding strength compared to many traditional extracorporeal knots.

4. Reduced Operative Cost and Time
Extracorporeal knotting is easier and faster for many surgeons compared to complex intracorporeal suturing.

5. Faster Recovery for Patients
Because it is part of minimally invasive surgery, patients usually experience less pain, smaller scars, and quicker return to normal activity.

Scientific Evidence

Clinical studies evaluating clipless laparoscopic cholecystectomy using Mishra’s Knot show promising outcomes. In one prospective study, operative time averaged about 62 minutes with low complication rates and very low material cost (around $10–14 for suture). This demonstrates the feasibility and economic advantage of the technique.

Importance at World Laparoscopy Hospital

World Laparoscopy Hospital has played a major role in teaching and global dissemination of Mishra’s Knot technique. Thousands of surgeons and gynecologists have been trained in advanced laparoscopic suturing and knotting techniques under expert guidance.

The technique is now used worldwide in procedures such as cholecystectomy, hernia repair, gynecologic surgeries, and appendectomy, highlighting its versatility and clinical importance.

Future Perspective

With the increasing focus on cost-effective and safe surgery, clipless laparoscopic techniques like Mishra’s Knot are gaining global acceptance. As training improves and laparoscopic suturing skills become more widespread, such techniques will likely reduce dependence on disposable surgical devices.

Conclusion

Laparoscopic cholecystectomy using Mishra’s Knot represents a significant advancement in minimally invasive surgery. It offers a safe, reliable, and economical method for ligating the cystic duct and artery. The technique reflects the philosophy of modern laparoscopic surgery—precision, safety, and affordability. Through institutions like World Laparoscopy Hospital, this innovative method continues to improve surgical outcomes and expand access to high-quality minimally invasive surgery worldwide.
