The bile duct is connected to the gallbladder. In patients with bile duct stones, the function of the gallbladder is also affected to a certain extent, so usually the gallbladder is also removed for bile duct stones. Bile is secreted by the liver and stored in the gallbladder. After the body has eaten, bile is discharged through the cystic duct to the common bile duct and then to the small intestine, between which it is also stored in the gallbladder. Bile duct stones are categorized as intrahepatic bile duct stones, and extrahepatic bile duct stones. Extrahepatic bile duct stones are further divided into primary and secondary. 1. If stones form in the bile ducts, the gallbladder that is connected to them may be involved in the formation of the stones, and there may also be stones in the gallbladder, so usually, the gallbladder will be removed at the same time. 2. After the bile duct is diseased, the function of the gallbladder will be affected to a certain extent, and its function of storing bile will be reduced or even disappeared, and the gallbladder will become a diseased gallbladder at this time, therefore, the gallbladder will be removed when bile duct stone extraction is performed. 3. In addition, after bile duct surgery (especially choledochotomy and lithotripsy), the gallbladder as a storage organ, the possibility of cholecystitis rises, and in the future, there is a need for surgery due to gallbladder stones, cholecystitis may need to be operated. If you suffer from bile duct stones, you should consult your doctor to determine the surgical plan for early treatment.
