At present, laparoscopic cholecystectomy is the gold standard for cholecystectomy because laparoscopic surgery has the following advantages: 1, good surgical exposure, less trauma: the exposure of the surgical field is full and clearer than that of traditional surgery; surgical operation is less damaging, and parts outside the surgical area will not be subjected to unnecessary interference with the operation, and abdominal adhesions rarely occur after the operation. 2.Little pain, quick recovery: the surgical trauma is far less than open surgery, early postoperative activities can get out of bed and eat, the patient is generally 7 days after the operation to fully recover, and can be put into normal work, life. Short hospitalization time: patients can be discharged from hospital in 3-4 days after surgery. 4, good cosmetic effect: after the postoperative abdominal wall incision healing, the scar is not obvious, there is no open surgery as long as the surgical scar. Of course, open cholecystectomy still has its own necessity: for complex gallbladder surgery; in difficult laparoscopic surgery, timely transit can avoid the occurrence of side injuries; and in some areas where laparoscopic surgery is not carried out, open cholecystectomy still plays its role.
