Day surgery, also known as outpatient surgery, is a medical procedure that allows patients to undergo surgery and return home on the same day. This type of surgery is typically less complex and involves shorter recovery times compared to traditional inpatient procedures. Common examples include arthroscopy, gallbladder removal, and cataract surgery. Patients usually arrive at the hospital or surgical center in the morning, receive anesthesia, and have their procedure performed. After a brief recovery period, they are monitored before being discharged. Day surgery is designed to minimize hospital stays, reduce costs, and enhance patient convenience.
