​In this comprehensive lecture, Dr. R. K. Mishra explains the latest surgical innovations for managing Gastroesophageal Reflux Disease (GERD). This in-depth session covers Fundoplication, LINX, and Transoral Incisionless Fundoplication (TIF)—three advanced techniques that are transforming GERD treatment worldwide.

Introduction to GERD

Gastroesophageal reflux disease (Gastroesophageal Reflux Disease) is a chronic condition in which stomach acid frequently flows back into the esophagus, leading to symptoms such as heartburn, regurgitation, chest discomfort, chronic cough, and even damage to the esophageal lining. While lifestyle modifications and medications like proton pump inhibitors (PPIs) are effective for many patients, a significant number continue to experience persistent symptoms or complications, necessitating advanced surgical or endoscopic interventions.

In this lecture, we explore three cutting-edge treatment options—Fundoplication, LINX, and TIF (Transoral Incisionless Fundoplication)—as explained by Dr. R. K. Mishra, a globally recognized expert in minimally invasive and robotic surgery.

Understanding the Need for Advanced Treatment

When medical therapy fails or when complications such as Barrett’s esophagus, strictures, or severe regurgitation occur, surgical intervention becomes essential. The goals of advanced GERD treatment include:

• Restoring the function of the lower esophageal sphincter (LES)
• Preventing acid reflux
• Improving quality of life
• Reducing dependence on long-term medication

Overview

Laparoscopic fundoplication is considered the gold standard surgical treatment for GERD. It involves wrapping the upper part of the stomach (fundus) around the lower esophagus to reinforce the LES.

Types of Fundoplication

• Nissen Fundoplication (360° wrap) – Complete wrap
• Toupet Fundoplication (270° wrap) – Partial posterior wrap
• Dor Fundoplication (anterior wrap) – Partial anterior wrap

Procedure Steps

1. Creation of pneumoperitoneum
2. Dissection of the esophageal hiatus
3. Mobilization of the gastric fundus
4. Crural repair (if hiatal hernia present)
5. Formation of the fundoplication wrap

Advantages

• Highly effective long-term reflux control
• Durable results
• Suitable for severe GERD and large hiatal hernias

This lecture by Dr. R. K. Mishra provides a comprehensive explanation of how to use the Harmonic Scalpel in laparoscopic surgery. In this educational lecture, viewers will learn essential tips, correct techniques, and important safety measures for the effective and safe use of the Harmonic Scalpel during minimally invasive procedures.

The harmonic scalpel has become an indispensable energy device in modern laparoscopic surgery due to its precision, safety profile, and efficiency. Unlike conventional electrosurgery, the harmonic scalpel uses ultrasonic vibration to cut and coagulate tissues simultaneously, producing minimal lateral thermal spread. Under the guidance and teachings of Dr. R. K. Mishra, a pioneer in minimal access surgery, surgeons worldwide have adopted standardized techniques that emphasize safety, anatomical respect, and optimal outcomes.

The harmonic scalpel works by converting electrical energy into mechanical ultrasonic vibrations at approximately 55,500 Hz. These vibrations denature protein within tissue, leading to effective coagulation while allowing precise cutting. One of the major advantages of this technology is reduced smoke production, clearer laparoscopic vision, and minimal tissue charring, making it particularly useful in procedures such as laparoscopic cholecystectomy, hysterectomy, appendectomy, and colorectal surgery.

Proper use of the harmonic scalpel begins with correct port placement and ergonomic positioning. The surgeon should always maintain a clear view of the active blade and ensure that surrounding vital structures—such as bile ducts, ureters, bowel, and major vessels—are well identified before activation. As emphasized by Dr. R. K. Mishra, the scalpel should be used with gentle traction–countertraction to allow effective tissue sealing. Excessive force or prolonged activation must be avoided, as it can compromise hemostasis and increase the risk of thermal injury.

Technique plays a critical role in maximizing safety. The harmonic scalpel should be activated intermittently rather than continuously, allowing tissue cooling between activations. When sealing vessels, especially those up to 5 mm in diameter, the jaws must be fully closed and kept still until complete coagulation is achieved. Cutting should only be performed after visual confirmation of adequate sealing. Surgeons should also avoid contact of the active blade with metal clips or trocars to prevent instrument damage and energy dispersion.

Safety is paramount when using any energy device. Although the harmonic scalpel has a lower lateral thermal spread compared to monopolar cautery, inadvertent injury can still occur if basic principles are ignored. Dr. R. K. Mishra strongly advocates structured training, simulation practice, and adherence to energy safety protocols. Surgeons must always deactivate the device before removing it from the abdominal cavity and remain vigilant about insulation integrity and instrument positioning.

In conclusion, the harmonic scalpel is a powerful and versatile tool in laparoscopic surgery when used with proper knowledge and technique. Following the tips, operative principles, and safety guidelines taught by experts like Dr. R. K. Mishra ensures reduced complications, improved surgical precision, and better patient outcomes. Mastery of the harmonic scalpel is not just about technology, but about disciplined surgical practice and respect for tissue biology.

Extracorporeal knot tying is a fundamental skill in laparoscopic surgery and plays a vital role in achieving secure ligation, hemostasis, and tissue approximation during minimally invasive procedures. Mastery of this technique is especially important for surgeons in training, as it offers efficiency, reliability, and ease of learning compared to intracorporeal knot tying. Under the guidance of Dr. R.K. Mishra, a pioneer in laparoscopic surgery and founder of World Laparoscopy Hospital, this article outlines the principles and step-by-step method of extracorporeal knot tying in laparoscopy.

What Is Extracorporeal Knot Tying?

Extracorporeal knot tying refers to the formation of a surgical knot outside the patient’s body, which is then advanced into the abdominal cavity using a knot pusher through a laparoscopic port. This technique is widely used for ligating pedicles, closing defects, and securing sutures in various laparoscopic procedures such as cholecystectomy, hernia repair, appendectomy, and gynecological surgeries.

Advantages of Extracorporeal Knot Tying

Extracorporeal knot tying offers several advantages, especially for beginners:

• Easier to learn and perform than intracorporeal knots

• Requires less advanced hand-eye coordination

• Saves operative time

• Provides strong and reliable knot security

• Useful in deep or narrow operative fields

Dr. R.K. Mishra emphasizes that proper technique and knot selection are crucial to prevent loosening or slippage after placement.

Instruments Required

To perform extracorporeal knot tying effectively, the following instruments are commonly used:

• Laparoscopic needle holder

• Knot pusher (metallic or plastic)

• Laparoscopic grasper

• Appropriate suture material (e.g., Vicryl, PDS, or silk)

Step-by-Step Technique of Extracorporeal Knot Tying

Step 1: Placement of the Suture

The needle is introduced into the abdominal cavity through a trocar, and the target tissue is sutured using laparoscopic instruments. Both free ends of the suture are brought outside the abdomen through the port.

Step 2: Knot Formation Outside the Body

Outside the patient, a secure surgical knot is formed manually. Commonly used knots include the square knot or surgeon’s knot, depending on the tissue tension and suture material.

Step 3: Loading the Knot Pusher

One limb of the suture is passed through the eye or channel of the knot pusher. The knot is positioned close to the tip of the knot pusher to ensure smooth advancement.

Step 4: Advancing the Knot into the Abdomen

The knot pusher is gently introduced through the trocar and advanced along the suture toward the target tissue under direct laparoscopic vision.

Step 5: Securing the Knot

Once the knot reaches the desired position, steady pressure is applied using the knot pusher while maintaining tension on the standing end of the suture. This ensures proper seating of the knot without tissue damage.

Step 6: Additional Throws

Additional knot throws may be applied in the same manner to enhance security. After confirming adequate tension and hemostasis, excess suture is cut.

Common Mistakes and How to Avoid Them

Dr. R.K. Mishra highlights common errors such as:

• Inadequate knot tightening

• Excessive tension leading to tissue necrosis

• Poor knot positioning

• Slippage due to incorrect knot type

These can be avoided through regular practice, correct suture selection, and strict adherence to laparoscopic principles.

Training and Skill Development

Extracorporeal knot tying is an essential component of laparoscopic training programs at World Laparoscopy Hospital. Surgeons are encouraged to practice on box trainers and simulators before performing the technique in live surgery. Consistent practice improves precision, speed, and confidence.

Conclusion

Extracorporeal knot tying is a cornerstone skill in laparoscopic surgery that combines simplicity with effectiveness. When performed correctly, it ensures secure suturing while minimizing operative time and complications. Under the expert guidance of Dr. R.K. Mishra, surgeons can develop proficiency in this technique, contributing to safer and more efficient minimally invasive surgeries.
