LESS technique
Also written as: LESS — Laparoendoscopic Single-Site Surgery
A surgical approach using a single incision, typically at the umbilicus, for all instrument access during laparoscopy.
Full Definition
LESS technique represents an evolution in minimally invasive surgery toward scarless procedures, utilizing a single umbilical incision for camera and instrument insertion. This approach requires specialized multichannel ports and articulating instruments to overcome the technical challenges of instrument collision and limited triangulation. While offering superior cosmetic outcomes, LESS demands advanced laparoscopic skills and is associated with longer operative times and learning curves for most procedures.
