Transumbilical single-hole laparoscopic cholecystectomy: It is a new procedure with a transumbilical approach. The incision is made at the navel, and the incision can be covered by the umbilical crease, which has a satisfactory cosmetic effect. The postoperative recovery is fast, the hospital stay is short, and the hospital costs are reduced, and patients can generally be discharged on the second day after surgery. Transumbilical single-port laparoscopic surgery is the most cutting-edge minimally invasive technology in the world, in which surgical instruments and equipment enter the abdominal cavity through the umbilical port and use the umbilical crease wall to cover the surgical incision. The transumbilical single-hole laparoscopic technique is a traditional laparoscopic surgery from four-hole, three-hole, two-hole to one-hole after the angle becomes zero, which poses a new challenge to the main surgeon in terms of experience and skills, and only a few hospitals in China can master this technique in a mature way transumbilical single-hole laparoscopic minimally invasive technique. Compared with traditional laparoscopic abdominal minimally invasive surgery, it uses a one-hole laparoscopic system device, which enters through the navel opening and automatically builds a cavity to reveal the operative field; you can eat and get out of bed 8~10 hours after surgery; the wound does not need to be removed. The operation is simple, safe and reliable, with short hospitalization time and low medical cost. The umbilical incision of single-hole laparoscopic surgery is only 1~2 cm, because the skin folds at the umbilicus can cover the incision, thus achieving the purpose of scarless surgery. Single-port laparoscopic cholecystectomy has outstanding characteristics of minimally invasive, safety, economy, aesthetics, and less postoperative pain.
