In reality, we often see patients asking their doctors, or patients asking each other, whether the stones can be removed by laparoscopic surgery with only 3 small holes drilled in the abdominal wall? On the surface, it is true that it is difficult to remove all the stones by drilling only 3 small holes in the abdominal wall. However, if we understand the mystery of laparoscopic surgery, everything will be clear. The gallbladder holding forceps, flushing suction device, stripping hook, etc.; dissect the corner of the bile groin, free the gallbladder duct, place a titanium clip at 0.5 cm from the common bile duct, cut the gallbladder duct, separate and cut (electrocoagulation) the gallbladder artery, free the gallbladder with the stripping hook, free the gallbladder from the gallbladder bed, and electrocoagulate the wound to stop bleeding. Depending on the size of the gallbladder and the number of stones, different sites are selected and the gallbladder stump is grasped with teeth under television surveillance, the gallbladder is pulled into the trocar and removed along with the trocar. The abdominal cavity is inspected, drains are placed if necessary, the instruments are removed, and the abdomen is drained; the gas is then removed from each trocar, and the incision is closed with intradermal sutures or band-aids. From the whole procedure, laparoscopic cholecystectomy is the same as open cholecystectomy, except that the surgical method is different, and the whole gallbladder is also removed completely, so the stones can be removed.
