Surgery done in a clinic or a hospital without an overnight stay either before or after the operation. Improvements in surgery – especially the introduction of MINIMALLY INVASIVE SURGERY (MIS) – as well as more eﬀective methods of ANAESTHESIA have simpliﬁed many procedures and reduced the physical and mental stress on patients. Patients undergoing day surgery should be accompanied home by a friend or relative. Occasionally a patient may develop complications that require a post-operative stay in hospital.
