Summary
New surgical tools enable gasless laparoscopy by displacing the abdominal wall. This technique allows standard instruments via small incisions, avoiding pneumoperitoneum risks and improving surgical options.
Area of Science:
- Minimally Invasive Surgery
- Surgical Technology Development
Background:
- Pneumoperitoneum in laparoscopy presents technical and physiological challenges.
- Carbon dioxide insufflation can lead to complications.
Purpose of the Study:
- To introduce a novel fan retractor and mechanical lifting arm system.
- To enable gasless laparoscopic procedures via planar abdominal wall displacement.
Main Methods:
- Development of a fan retractor and mechanical lifting arm.
- Application in gynecologic, general surgical, and trauma procedures.
- Utilized minilaparotomy incisions for instrument access.
Main Results:
- Successful completion rate of 86.5% in 104 patients.
- Facilitated use of conventional open surgical instruments.
- Enabled laparoscopy without pneumoperitoneum.
Conclusions:
- The developed system offers a viable alternative to gas insufflation.
- Further research is needed to fully establish benefits.
- Potential to overcome limitations of traditional laparoscopic insufflation.
