Endoscopic threaded imaging port (EndoTIP) for laparoscopy: experience with different body weights.

Area of Science:

• Minimally Invasive Surgery
• Surgical Access Techniques
• Laparoscopy

Background:

• A novel trocar-less laparoscopic access cannula was developed for primary port insertion.
• The system features a threaded cannula with a blunt tip, enabling radial fascial and muscle fiber spreading for insertion.
• Magnified visualization is provided during insertion and exit.

Purpose of the Study:

• To evaluate the safety and efficacy of a new trocar-less laparoscopic access cannula.
• To assess the device's performance across various patient weight categories, including obesity.

Main Methods:

• The cannula was utilized in 234 consecutive patients undergoing laparoscopic procedures.
• Patient cohorts included normal weight, mildly obese, moderately obese, and markedly obese individuals (BMI ≥35).

Main Results:

• No instrument-related or insertion-related complications occurred.
• Insertion was successful in all cases, with slightly longer times in morbidly obese patients with prior umbilical surgery.
• No port-site hernias were observed during 6-48 months of follow-up.

Conclusions:

• The reusable, trocar-less cannula is a safe and effective method for laparoscopic primary port insertion.
• The device is suitable for patients of all body weights, including those with obesity.
