Laparoendoscopic Single-Site Surgery (LESS) has made its fore ways into clinical practice, and allows foreseeing a less traumatic surgery without visible scar. Its development reminds the revolution associated with apparition of laparoscopy. Actual clinical experience gained showed that LESS is valid, seems as safe as conventional laparoscopy, while offering patients a surgery without trace. LESS development, which requires advanced laparoscopy training, has made surgeons and industry rethink surgical ergonomic thus allowing rapid technical innovations. These innovations will change minimally invasive surgery in a near future, if they did not already. We, now, have to control its evolution to build a safe and reasonable future for minimally invasive surgery combining patients' desire and safety, populations needs.
