Sedimentous gallbladder stones must be removed, which means that the gallbladder must be removed. Sedimentous gallbladder stones are stones inside the gallbladder that are very small, usually the size of a grain of rice or a green bean, or even smaller than a grain of rice in some cases. The main characteristic of mud-like gallbladder stones is that the stones may drain downward on their own, that is, along the cystic duct and common bile duct into the patient’s intestine, which may be dangerous or may have complications during the process of stone drainage, such as stone entrapment in the common bile duct, which may lead to acute cholangitis, manifested by increased abdominal pain, high fever, and jaundice. If the stone is in the duodenal papilla and obstruction occurs, it may lead to pancreatic inflammation, further aggravation of abdominal pain, and may even lead to infection around the pancreas and necrosis of the pancreas.
