At present, due to the limitation of instruments and experience, single-port laparoscopic surgery is still limited to traditional three-port laparoscopic surgery such as cholecystectomy, appendectomy, ovarian cyst debridement, adrenalectomy, etc. Few complex laparoscopic surgeries are involved, and there is a gap in the liver field. The single-port laparoscopic technique has more outstanding characteristics of minimally invasive, safety, economy, aesthetics and less postoperative pain than traditional laparoscopic surgery. The surgery is done by placing multiple adjacent trocar pins or a multi-channel Trocar in a single site with the help of laparoscopic instruments. Only a 1-2 cm incision is left in the abdominal wall after surgery, which is less traumatic, less painful after surgery, faster recovery, and significantly reduces the patient’s physical and mental burden in the perioperative period. Because the umbilical skin folds can cover the incision, the incision scar is almost invisible after transumbilical single-port laparoscopic surgery, so it is also called “scarless surgery”. Single-port laparoscopic surgery requires more skill from the operator and requires overcoming the challenges of linear field of vision, loss of operating triangle, fights with instruments, and difficulties in organ exposure.
