Laparoscopic and robotic specimen retrieval system (Modified Nadiad Bag): Validation and cost-effectiveness study...

Area of Science:

• Urology
• Minimally Invasive Surgery

Background:

• Effective specimen retrieval is crucial in minimally invasive urology.
• Existing retrieval systems can be costly or complex.

Purpose of the Study:

• To construct and validate a cost-effective, indigenously made retrieval system (Modified Nadiad bag) for minimal access urology.

Main Methods:

• The Modified Nadiad bag was constructed using polyethylene roll, fishnet thread, and a ureteral catheter.
• It was utilized for organ retrieval in 50 Robot Assisted Radical Prostatectomies, 50 laparoscopic radical nephrectomies, 50 laparoscopic simple nephrectomies, and 18 laparoscopic adrenalectomies.
• Retrieval times were compared between expert and novice surgeons.

Main Results:

• No significant difference in retrieval times was observed between expert and novice surgeons (p=0.29).
• Organ size (p=0.83) and specimen weight (p=0.99) also showed no significant difference based on surgeon expertise.
• The system demonstrated efficacy across various laparoscopic and robotic procedures.

Conclusions:

• The Modified Nadiad bag is a cost-effective, easy-to-make retrieval solution.
• It minimizes the risk of tumor seeding and eliminates the need for a separate access sheath.
• The system's efficacy is independent of surgeon experience in laparoscopic and robotic procedures.
