Robot-assisted sleeve gastrectomy (rSG) is a modern form of laparoscopic (keyhole) weight-loss surgery, using the latest technology to achieve even greater precision than traditional technique. During the procedure, 60–80% of the stomach is removed, and the remaining part is shaped into a narrow "sleeve" that limits food intake.
