This video demonstrate laparoscopic veress needle. Dr R K Mishra explaining veress needle. A Veress needle is a spring-loaded needle used to create pneumoperitoneum for laparoscopic surgery. Of the three general approaches to laparoscopic access, the Veress needle technique is the oldest and most traditional and most widely used technique of access. Veress needle access is most commonly used access in Minimal Access Surgery.
Laparoscopic surgery has revolutionized modern surgical practice by minimizing tissue trauma and improving patient recovery. One of the most critical initial steps in laparoscopy is the creation of pneumoperitoneum, and the Veress needle remains one of the most commonly used instruments for this purpose. Introduced by the Hungarian physician Dr. János Veress, this needle has become a cornerstone of safe and effective minimally invasive surgery.
What Is a Veress Needle?
The Veress needle is a spring-loaded, hollow needle designed to safely access the peritoneal cavity. It consists of a sharp outer cannula and a blunt inner stylet that retracts during tissue penetration and springs forward once the peritoneal cavity is entered. This safety mechanism helps reduce the risk of injury to intra-abdominal organs and blood vessels.
Design and Components
A standard Veress needle typically measures 12–15 cm in length and 2 mm in diameter. Its key components include:
-
Sharp beveled outer needle for tissue penetration
-
Blunt inner stylet that advances automatically after entry
-
Spring mechanism to control the movement of the stylet
-
Luer-lock connector for attachment to CO₂ insufflation tubing
This simple yet effective design allows surgeons to establish pneumoperitoneum with precision.
Technique of Insertion
The Veress needle is commonly inserted through the umbilicus, where the abdominal wall is thinnest. After lifting the abdominal wall, the needle is advanced at an appropriate angle until a characteristic “click” is felt, indicating entry into the peritoneal cavity. Correct placement is then confirmed using methods such as:
-
Saline drop test
-
Aspiration test
-
Initial low-pressure CO₂ insufflation
Once proper placement is confirmed, carbon dioxide is insufflated to create adequate working space for laparoscopic instruments.
Advantages of the Veress Needle
The Veress needle offers several benefits:
-
Quick and minimally invasive access
-
Reduced tissue trauma
-
Widely available and cost-effective
-
Familiarity among surgeons worldwide
It is especially useful in primary laparoscopic procedures where adhesions are unlikely.
Limitations and Complications
Despite its advantages, Veress needle insertion is a blind technique and may be associated with complications such as:
-
Preperitoneal insufflation
-
Bowel or vascular injury
-
Failure to achieve pneumoperitoneum
These risks can be minimized through proper patient selection, correct technique, and adequate surgical training.
Veress Needle vs Open (Hasson) Technique
The Veress needle technique is faster and less invasive, while the open (Hasson) technique offers direct visualization and is preferred in patients with previous abdominal surgeries or suspected adhesions. Both methods have their place in laparoscopic practice, and the choice depends on surgeon experience and patient factors.
Conclusion
The laparoscopic Veress needle remains a vital instrument in minimally invasive surgery. When used with proper technique and caution, it allows safe and efficient creation of pneumoperitoneum, paving the way for successful laparoscopic procedures. Mastery of Veress needle insertion is an essential skill for every laparoscopic surgeon.
