Video of How to Create Safe Pneumoperitoneum: Techniques and Precautions in Laparoscopic Surgery
In this essential video titled "How to Create Safe Pneumoperitoneum: Techniques and Precautions in Laparoscopic Surgery," we provide a comprehensive overview of the critical first step in any laparoscopic procedure—establishing pneumoperitoneum. Proper creation of pneumoperitoneum not only ensures optimal visualization and working space within the abdominal cavity but also minimizes the risk of serious complications such as vascular or bowel injuries. This tutorial is ideal for surgical trainees, operating room personnel, and practicing surgeons looking to reinforce best practices in safe laparoscopic access.
What Is Pneumoperitoneum and Why Is It Important?
Pneumoperitoneum refers to the insufflation of carbon dioxide (CO₂) into the peritoneal cavity to create a working space for laparoscopic surgery. It allows the surgeon to view and access internal organs with minimal trauma. However, incorrect technique or improper entry can result in life-threatening complications, making this step one of the most critical in the procedure.
Techniques for Creating Pneumoperitoneum (Explained in the Video)
Veress Needle Technique
This is the most commonly used closed method. After making a small infra- or supraumbilical incision, a spring-loaded Veress needle is inserted perpendicularly (or at a 45-degree angle in thin patients). Safety confirmation tests such as the hanging drop method, aspiration test, and initial intra-abdominal pressure check are performed before insufflation begins.
Open (Hasson) Technique
Often preferred in obese or previously operated patients, this technique involves a small infraumbilical incision to expose the fascia, which is incised under direct vision. A blunt-tipped trocar or Hasson cannula is inserted and secured. CO₂ is then insufflated to achieve the desired intra-abdominal pressure.
Optical Trocar Entry
Used with visual-entry trocars, this method allows the surgeon to see each tissue layer as the trocar passes, reducing blind entry risks. It is especially useful in patients with no prior surgeries.
Safety Precautions and Best Practices
Always insert the Veress needle or trocar in the correct anatomical location—usually 2 cm below or above the umbilicus depending on body habitus.
Confirm intra-abdominal placement by observing low initial pressure (<10 mmHg) and free gas flow.
Avoid high-pressure insufflation initially; begin with slow insufflation at low flow rates to prevent vascular compression and gas embolism.
In patients with prior abdominal surgeries, consider alternative access points like Palmer’s point (left upper quadrant) to avoid adhesions.
Be cautious with thin, pediatric, or cachectic patients where structures are closer to the abdominal wall.
Common Complications to Avoid
Preperitoneal insufflation leading to failed pneumoperitoneum
Injury to bowel or major vessels, especially during blind trocar insertion
Subcutaneous emphysema due to misplaced insufflation
Gas embolism, though rare, can be fatal if not managed promptly
Conclusion
Creating a safe pneumoperitoneum is the foundation of every successful laparoscopic surgery. The choice of technique should be tailored to the patient’s anatomy and surgical history, and each step must be carried out with precision, vigilance, and adherence to safety protocols. In this video, you’ll learn the practical techniques, intraoperative tips, and preventive strategies that can dramatically reduce complications and improve surgical outcomes.
