Cholecystitis and gallbladder stones are common hepatobiliary surgical diseases, and currently more than 95% of them are removed by less invasive laparoscopic cholecystectomy, but the patient will be left with 3-4 small scars on the upper abdomen. With the increasing demand for beauty from patients, “scarless” cholecystectomy surgery has emerged. A 1-2 cm size incision is made from the patient’s umbilicus, the gallbladder is removed from the umbilicus using conventional laparoscopic instruments, and the umbilical incision is sutured in one stage, which is a minimally invasive and cosmetic surgery. Therefore, the procedure is minimally invasive and cosmetic, also known as “scarless cosmetic surgery” for gallbladder removal.
