The incidence of gallbladder stones and gallbladder polyps is increasing year by year. If the stones in the gallbladder block the gallbladder duct and make the bile drainage poor, it will cause secondary bacterial infection and form cholecystitis. Some gallstones may also cause pancreatitis when they are dislodged into the common bile duct, which can lead to death in serious cases if not treated in time. In addition, repeated irritation of gallbladder by stones may also lead to cancer. Therefore, it is important to remove stones and polyps from the gallbladder as early as possible. At present, the widely adopted method is to cut out the whole gallbladder. However, the gallbladder is an important digestive organ of the human body, and after removal, it will affect the digestive function and easily cause digestive symptoms such as diarrhea, abdominal pain and loss of appetite, and even increase the incidence of colorectal cancer. At present, with the help of advanced electronic choledochoscopy technology, a small hole can be made in the abdominal wall to enter the gallbladder to remove the stones; for gallbladder polyps, all polyps can be removed under direct vision, preserving the gallbladder, and for malignant cases, radical surgery for gallbladder cancer can be performed. In this way, we can kill two birds with one stone, not only can we get rid of the disease, but also preserve the gallbladder, so that you will always have “liver and gallbladder”. The recurrence rate of stones after surgery is 1%-5%, and the recurrence rate of polyps is 1%. Of course, for atrophied gallbladder, suspected malignancy, gallbladder wall thickness greater than 5mm, and intraoperative choledochoscopic confirmation of loss of normal anatomy of the gallbladder should be removed.
