This video demonstrate Totally Extra-peritoneal Hernia Surgery (TEP). A hernia is repaired generally using a synthetic mesh either with open surgery or increasingly using less invasive laparoscopic procedures. The most common laparoscopic techniques for inguinal hernia repair are transabdominal preperitoneal (TAPP) repair and totally extraperitoneal (TEP) repair.
Hernia repair is one of the most common surgical procedures performed worldwide, and with advancements in surgical techniques, extra-peritoneal hernia surgery has emerged as a safe and effective approach, especially for patients requiring minimally invasive repair. This technique focuses on placing the surgical mesh outside the peritoneal cavity, reducing complications and improving recovery.

What is Extra-Peritoneal Hernia Surgery?

Extra-peritoneal hernia surgery is a type of minimally invasive hernia repair where the mesh is placed in the space outside the peritoneal cavity (preperitoneal space) rather than inside it. This technique avoids direct contact of the mesh with abdominal organs, reducing risks such as adhesions, bowel obstruction, and chronic pain.

It can be performed via open surgery or laparoscopic/robotic approaches, depending on the surgeon's expertise and the patient's condition.

Indications for Extra-Peritoneal Hernia Surgery

This approach is commonly recommended in cases of:

Inguinal hernia (both unilateral and bilateral)

Recurrent hernia after previous anterior repair

Patients at high risk of intra-abdominal adhesions

Hernias requiring minimally invasive techniques for faster recovery

Types of Extra-Peritoneal Hernia Surgery

Totally Extra-Peritoneal (TEP) Laparoscopic Repair

A minimally invasive procedure using small ports.

The mesh is placed in the preperitoneal space without entering the abdominal cavity.

Benefits include less postoperative pain, shorter hospital stay, and quicker return to normal activity.

Open Extra-Peritoneal Repair (e.g., Stoppa or Rives-Stoppa technique)

Involves a larger incision but places the mesh in the extra-peritoneal space.

Often used for large or complex hernias, including bilateral cases.

Surgical Steps (Laparoscopic TEP Example)

Anesthesia and Positioning – Patient under general anesthesia, supine position.

Creation of Preperitoneal Space – Using balloon dissector or blunt dissection.

Port Placement – Typically 3 small incisions for laparoscopic instruments.

Hernia Reduction – Contents of the hernia sac are carefully reduced.

Mesh Placement – Pre-shaped mesh is placed over the defect in the extra-peritoneal space.

Fixation and Closure – Mesh may be fixed with tacks or left unfixed depending on the technique; ports are closed.

Advantages of Extra-Peritoneal Hernia Surgery

Reduced risk of intra-abdominal complications

Lower recurrence rates compared to some traditional techniques

Minimally invasive approach leads to faster recovery

Less postoperative pain

Safe for bilateral hernias

Recovery and Postoperative Care

Most patients can resume normal activities within 1-2 weeks.

Pain is generally mild and managed with oral analgesics.

Avoid heavy lifting for 4-6 weeks.

Follow-up is essential to monitor for complications such as seroma or mesh infection.

Conclusion

Extra-peritoneal hernia surgery represents a modern, patient-friendly approach to hernia repair. Whether performed laparoscopically or via open surgery, it provides a safe, effective, and low-risk option for both primary and recurrent hernias. With advancements in robotic surgery, this technique is becoming increasingly precise, offering better outcomes and improved quality of life for patients.
