<unk> , also known as ambulatory surgery, day surgery, day case surgery, or same-day surgery, is surgery that does not require an overnight hospital stay. The term<unk> ” arises from the fact that surgery patients may enter and leave the facility on the same day. The advantages of<unk>  over inpatient surgery include greater convenience and reduced costs.<unk>  may occur in an inpatient facility, in a self-contained unit within a hospital (also known as a hospital<unk>  department), in a freestanding self-contained unit (also known as an ambulatory surgery center), or in a physician's office-based unit. Between the late 20th century and early 21st century,<unk>  has grown in popularity in many countries. In the United States, 65% of surgeries at hospitals in 2012 were conducted on an<unk>  basis, compared with 54% in 1992. Studies have shown that<unk>  is as safe as or safer than inpatient surgery. For instance, complication rates and post-surgical hospitalization or readmission rates are comparable, and pain and infection rates are lower after<unk>  than inpatient surgery. Nevertheless, articles in the newsmedia (such as some discussing the 2014 death of Joan Rivers after an<unk>  procedure) have questioned the safety of<unk>  performed at ambulatory surgery centers.
