Bile duct stones are stones that form in the bile ducts inside and outside the liver and are the most common biliary system disorder. Stone obstruction of the bile ducts causes bile stagnation and secondary bacterial infection leading to the occurrence of acute cholangitis. Repeated inflammation of the bile ducts can cause local wall thickening or scarring stenosis, and bile duct inflammation and stenosis can promote stone formation. The proximal end of the bile duct stenosis is passively dilated and the internal pressure is increased. Clinically, patients often present with right upper abdominal cramps, chills and fever, and jaundice Charcot’s (charcot) triad. Severe infection may result in shock and psychiatric abnormalities (Reynokds five signs), and recurrent symptoms may result in biliary cirrhosis followed by portal hypertension over time. China is a region with high incidence of biliary tract diseases, many patients suffering from gallbladder stones, biliary tract stone disease, misdiagnosed themselves as “stomach disease”, and take conservative treatment with Chinese medicine at the village doctor, often only when the biliary tract obstruction, liver function damage is serious; and more patients, even in the hospital for ultrasound examination of their own gallbladder stones, due to They do not know enough about the disease and do not seek medical treatment in time, and take oral Chinese medicine or proprietary Chinese medicine for the so-called “stone removal” treatment, hoping to remove gallbladder stones from the body, which not only does not remove the stones, but also leads to gallbladder stone patients with bile duct stones. Therefore, bile duct stones are a common and frequent disease in our city. Moreover, bile duct stones are very likely to induce biliary pancreatitis and acute obstructive suppurative cholangitis (AOSC), so patients with bile duct stones should be treated with surgery as early as possible!
