gasless laparoscopy
A laparoscopic technique that creates working space through mechanical abdominal wall retraction rather than gas insufflation.
Full Definition
Gasless laparoscopy is an alternative approach to conventional pneumoperitoneum-based surgery that uses external mechanical devices to lift and retract the abdominal wall, creating surgical working space without gas insufflation. This technique employs specialized retractors, lifting devices, or subcutaneous wires to elevate the anterior abdominal wall. Benefits include elimination of CO2-related complications, maintenance of normal respiratory physiology, and suitability for patients with severe cardiac or pulmonary disease. However, visualization and working space are typically more limited compared to conventional insufflation techniques.
Usage
Usage note: Hyphenate when used as a compound adjective (gasless-laparoscopy technique).
