At present, the types of day surgery are mainly limited to small and medium-sized elective surgeries with relatively controlled risk and mature technology. The most common surgery in general surgery, inguinal hernia surgery, including open surgery with local anesthesia and laparoscopic surgery for inguinal hernia, can be included in the day surgery categories. They also include thyroid and breast tumors and tumor removal on the body surface. Each hospital will choose the type of day surgery that fits the hospital’s specialties and technical advantages. In other words, the types of day surgery are different in each hospital. For example, our hospital focuses on inguinal hernia, thyroid, breast, and varicose veins. For patients with inguinal hernia, thyroid and breast benign masses, the day surgery program is started immediately after the patient arrives, and the relevant preoperative tests are completed quickly for accurate preoperative evaluation. If the patient can be included in day surgery and is physically fit, the specialist will immediately contact the operating room and perform the day surgery, with enhanced postoperative follow-up to ensure medical safety, so that the patient can complete the entire process of hospitalization, admission assessment, surgery, postoperative observation and discharge within 1-2 working days.
