What does a robotic low anterior resection (LAR) involve?

Robotic LAR is a minimally invasive surgery for rectal cancer that uses the Da Vinci surgical system. The surgeon operates from a console, controlling robotic arms with high-definition 3D visualization and wristed instruments. This allows precise removal of the diseased rectal segment while preserving the anal sphincter, following total mesorectal excision (TME) principles to ensure complete cancer clearance.
