Researchers developed new technologies for endoscopic colorectal resections, including a novel anvil insertion device and cable binding technique. This enabled a new combined laparoscopic-rectoscopic procedure, successfully tested in animals before clinical trials.

Area of Science:

  • Gastroenterology and Surgical Innovation
  • Minimally Invasive Surgery Technologies

Background:

  • Endoscopic colorectal resections require advanced technologies and refined surgical procedures.
  • Existing methods may present challenges in transanal anvil insertion and stump closure.

Purpose of the Study:

  • To develop novel technologies and a surgical procedure for endoscopic colorectal resections.
  • To establish a standardized animal model for evaluating a new combined laparoscopic-rectoscopic technique.

Main Methods:

  • Development of an air-proof transanal device for stapler anvil insertion.
  • Creation of a cable binding technique for colonic and rectal stump closure.
  • Performance of a combined laparoscopic-rectoscopic procedure in 32 animals, with 15 successful definitive cases.

Main Results:

  • Successful development of a new air-proof transanal anvil insertion device.
  • Successful development and implementation of the cable binding technique for stump closure.
  • Demonstration of a feasible and reproducible combined laparoscopic-rectoscopic procedure in an animal model.

Conclusions:

  • Technological innovations facilitate a novel combined laparoscopic-rectoscopic approach for colorectal surgery.
  • The developed procedure and technologies represent a standardized animal trial prior to human clinical investigation.
  • This research paves the way for advancements in minimally invasive colorectal surgery.
