Overview: Transumbilical single-port laparoscopic surgery is the most cutting-edge international minimally invasive technique in which surgical instruments and equipment enter the abdominal cavity through the umbilical orifice and use the umbilical crease wall to obscure the surgical incision. The transumbilical single-hole laparoscopic technique is a new challenge to the surgeon in terms of experience and skills, as the angle becomes zero after the traditional laparoscopic surgery is changed from four-hole, three-hole or two-hole to one-hole. Advantages: Minimally invasive transumbilical single-hole laparoscopic technique has more outstanding characteristics of minimally invasive, safety, economy, aesthetics and less postoperative pain compared with traditional laparoscopic abdominal minimally invasive surgery. Minimally invasive: The single-hole method is used to enter through the navel opening; no additional incision is made. Safety: The operation is performed under dual vision, i.e., direct and screened three-dimensional spatial view, with hand-eye operation; no pre-operative gastric tube or urinary catheter is required; the operation is less traumatic. It is as safe as traditional surgery. Economical: You can eat and get out of bed in 8~10 hours after surgery; the wound does not need to be removed. The operation is easy, safe and reliable, with a short hospital stay and low medical costs. Cosmetic: The umbilical incision of single-port laparoscopic surgery is only 1~2 cm, because the skin folds of the umbilicus can cover the incision, thus achieving the purpose of scarless surgery. With the above advantages, single-port laparoscopic minimally invasive surgery has occupied a place in the fields of cholecystectomy, fundoplication, appendectomy, bariatric surgery, etc. Meanwhile, it has been applied in urological surgeries such as prostatectomy, cystectomy, donor nephrectomy and gynecological surgeries such as hysterectomy, thus being recognized by more and more surgeons and welcomed by patients.
