Surgery is recommended for sedimentary gallstones because they are small and may drain down the cystic duct into the middle of the common bile duct. During the drainage process, the patient may have abdominal pain, fever, transient jaundice, and sometimes hospitalization in severe cases. If the stone has drained into the intestinal tract, the patient’s abdominal pain and jaundice may be relieved. If the stone becomes lodged or obstructed in the common bile duct or in the duodenal papilla, it may lead to severe cholangitis and pancreatitis, which is very serious. Surgery is recommended after a clear diagnosis of sedimentary gallstones. After the patient’s gallstones have been in the gallbladder for a long time, they may affect the gallbladder mucosa, such as inducing chronic cholecystitis or acute cholecystitis, and once the patient has an acute inflammatory attack on the gallbladder, the difficulty of surgery may increase and there may be certain risks.
