Transvaginal endoscopic cholecystectomy using a simple magnetic traction system.

Area of Science:

• Minimally invasive surgery
• Surgical innovation
• Gastroenterology

Background:

• Natural orifice transluminal endoscopic surgery (NOTES) faces limitations due to instrument constraints.
• Advancements in surgical instrumentation are crucial for expanding NOTES applications.

Purpose of the Study:

• To evaluate the feasibility of a novel magnetic traction system for transvaginal NOTES cholecystectomy.
• To assess the efficacy of magnetic retraction in achieving adequate surgical exposure.

Main Methods:

• Transvaginal endoscopic cholecystectomies were performed in a porcine model (n=4).
• A magnetic traction system, utilizing an endoscopic clip and external magnet, was employed for gallbladder retraction.
• Gallbladder dissection and retrieval were conducted using the magnetic system.

Main Results:

• Successful transvaginal NOTES cholecystectomies were achieved in all subjects.
• The magnetic traction system provided effective, multi-axial retraction for gallbladder exposure.
• Minor liver bed bleeding was the only complication; mean procedure time was 133.8 minutes.

Conclusions:

• The magnetic traction system is feasible and effective for transvaginal NOTES cholecystectomy.
• This innovative system overcomes key limitations in current NOTES procedures.
• Further development holds promise for advancing NOTES surgery.
