Challenges and lessons learned from NOTES cholecystectomy initial experience: a stepwise approach from the laboratory...

Area of Science:

• Minimally Invasive Surgery
• Surgical Innovation
• Gastroenterology

Background:

• Natural orifice transluminal endoscopic surgery (NOTES) aims for incisionless procedures.
• NOTES cholecystectomy represents a significant technological advancement.
• Extensive laboratory work in animal models preceded human application.

Purpose of the Study:

• To evaluate the feasibility and outcomes of NOTES cholecystectomy in human patients.
• To build upon laboratory findings from extensive pig model studies.
• To advance the development of incisionless surgical techniques.

Main Methods:

• Over 250 cholecystectomies were performed in pig models.
• Ten transvaginal and six transgastric human cholecystectomies were conducted between May 2007 and November 2008.

Main Results:

• All human procedures were successful with a mean operative time of 120 minutes.
• No intraoperative or postoperative complications were observed.
• Patients experienced prompt recovery, minimal postoperative pain, and were discharged on postoperative day two.

Conclusions:

• NOTES cholecystectomy enhances laparoscopic advantages, offering reduced pain and scarring.
• This experience is a crucial step toward developing incisionless NOTES surgery.
• Further research and comparative studies are necessary to broaden patient applicability.
