There are laparoscopic minimally invasive surgery and traditional open surgery for gallstones. Laparoscopic minimally invasive surgery usually takes about half an hour to one hour, while traditional open surgery usually takes about one hour to two hours, with variations in the exact time, so it is recommended that you consult your local hospital. Currently, cholecystectomy is divided into laparoscopic cholecystectomy and open cholecystectomy, one is performed with the help of laparoscopy, which is less traumatic and painful, requires less anesthetic and quicker awakening, so the operation time is short. While open cholecystectomy is traumatic and painful, in addition to a high dose of anesthesia, the stitches take a long time to close, so the operation takes a long time. As each person’s specific condition is different, such as gallbladder with or without edema inflammation, adhesions, etc., the level of hospitals also differ, so the specific time for different patients is not consistent, it is recommended to consult the local hospital.
