Safe Veress Needle Intraperitoneal Placement and Safer Laparoscopic Entry

Area of Science:

• Minimally Invasive Surgery
• Surgical Techniques
• Patient Safety

Background:

• Laparoscopic bowel and vascular injuries are serious complications, often occurring during the initial entry phase.
• These injuries contribute significantly to patient morbidity and mortality.
• Current entry techniques require refinement to enhance safety.

Purpose of the Study:

• To demonstrate three novel techniques for minimizing injury risk during laparoscopic entry.
• To provide a reliable and safe method for achieving intraperitoneal access.
• To improve intraoperative recognition of potential complications.

Main Methods:

• Description of caudal umbilical displacement for safe Veress needle insertion.
• Guidance on using left upper quadrant entry in specific scenarios.
• Demonstration of visualized trocarless cannula for real-time injury recognition.

Main Results:

• Caudal umbilical displacement creates a 6 cm buffer from the common iliac vessels.
• Intraperitoneal entry is indicated by an entry pressure below 9 mm Hg.
• Visualized trocarless cannula converts linear force to radial torque, aiding injury detection.

Conclusions:

• The presented techniques effectively decrease the risk of bowel and vascular injuries during laparoscopy.
• These methods enhance intraoperative recognition of critical injuries.
• Implementation of these techniques contributes to improved patient outcomes in laparoscopic surgery.
