Cameraless peritoneal entry in abdominal laparoscopy.

Area of Science:

• Minimally Invasive Surgery
• Surgical Access Techniques
• Patient Safety in Laparoscopy

Background:

• Peritoneal access in laparoscopy carries risks of intra-abdominal structure injury.
• Current methods for peritoneal access lack consensus on the optimal technique.
• A simplified, safe technique could reduce the learning curve for surgeons.

Purpose of the Study:

• To evaluate the safety and efficacy of the fluid-based peritoneal entry indication technique (C-PET) for laparoscopic surgery.
• To assess the complication rate and time required for peritoneal access using C-PET.
• To determine the applicability of C-PET across diverse patient populations.

Main Methods:

• Prospective review of 99 consecutive patients undergoing upper-abdominal laparoscopic surgery.
• Utilized the fluid-based peritoneal entry indication technique (C-PET) with EndoTIP trocar for peritoneal access.
• Data collected on successful entry, time to access, and any associated injuries.

Main Results:

• Successful peritoneal access was achieved in 90.9% of patients (90/99).
• No trocar-related or other injuries occurred during peritoneal access.
• Mean time to peritoneal access was 21.4 seconds; fewer failures occurred with experience.

Conclusions:

• C-PET is a simple, safe, and effective method for peritoneal access in laparoscopic surgery.
• The technique demonstrated no complications and was effective in obese and previously operated patients.
• C-PET's ease of use and lack of reliance on visual layer identification suggest potential for broader application, including by non-surgeons.
