Ambulatory surgery refers to the process of admitting patients, administering anesthesia and surgical care, and discharging patients home following an appropriate level of recovery on the same day. The word ambulatory is derived from the latin word ambulare, which means ''to walk''. This means that patients treated on an ambulatory basis do not require hospitalisation and achieve a level of postoperative 'home readiness' that allows them to go home within hours of procedure completion.
