As a type of stone disease, the incidence of common bile duct stones has been increasing. So how much do we know about it? What acts as a booster to push common bile duct stones to us? Let’s learn more about it together. Common bile duct stones are formed in the common bile duct, which is called primary common bile duct stones, and most of these stones are bile pigment stones. Because primary common bile duct stones can be produced in the bile duct, it is often less effective than secondary common bile duct stones. After surgery to remove the stones, sometimes the gallstones will recur, which often makes the treatment difficult. 2. Secondary common bile duct stones mean that the stones in the common bile duct were initially formed in the common bile duct by stones from the gallbladder entering the common bile duct through the gallbladder. Therefore, stones removed from the common bile duct and stones from the patient’s gallbladder are very similar in appearance and color and have the same chemical composition. However, not every patient with gallbladder stones has stones in the gallbladder that fall into the common bile duct and cause secondary common bile duct stones. If the stones in the gallbladder are small and the patient’s cystic duct is thick, the patient is more likely to develop secondary common bile duct stones. The risk of common bile duct stones depends on the degree of stone obstruction and the presence of a biliary tract infection, with attacks of abdominal pain, chills, fever and jaundice. However, if the biliary tract infection is severe and complicated by acute obstructive purulent cholangitis, the disease develops rapidly, and nearly half of the patients soon show signs of infectious shock such as irritability, delirium or drowsiness, coma and decreased blood pressure and acidosis, etc. If not treated in time, death often occurs within 1-2 days or even hours due to circulatory failure.
