Pronunciation: less

Also written as: LESS — Laparoendoscopic Single-Site surgery

Laparoendoscopic Single-Site surgery, minimally invasive technique using a single incision point.

Full Definition

LESS (Laparoendoscopic Single-Site surgery) is an advanced minimally invasive surgical technique that performs laparoscopic procedures through a single incision, typically at the umbilicus. This approach uses specialized multichannel ports or multiple individual trocars placed through the same incision to accommodate the laparoscope and surgical instruments. LESS offers potential cosmetic advantages with virtually scarless surgery, though it presents technical challenges including instrument crowding and loss of triangulation.

Usage

Usage note: Written in all capitals; distinguish from the common English word 'less' in surgical contexts.
