In bile duct stone removal, no matter which option is applied, the first requirement is that the bile duct stones should not exceed 0.5 cm, because stones over 0.5 cm are often difficult to remove, especially stones of 0.5-1 cm, which can easily cause obstruction during stone removal, leading to acute cholangitis and acute pancreatitis, which are more dangerous complications. For the bile duct stones that meet the criteria of stone removal, generally consider drug stone removal or gastroscopic removal, etc.: 1. Drug stone removal: use ursodeoxycholic acid for bile treatment, which can effectively promote bile discharge, some relatively small stones or sediment-like stones, in the process of bile discharge together with the discharge to reach the intestine, so as to achieve the effect of stone removal. You can also use some proprietary Chinese medicines, including anti-inflammatory and bile tablets and gallstone tablets, which have a certain effect of bile and stone removal. You can also use some Chinese medicine preparations, such as lithotripsy soup. However, the prescription of such herbal preparations must be done under the guidance of a professional Chinese medicine practitioner, and the corresponding herbal medicine should be prescribed according to the characteristics of the individual disease for regulation. Regardless of the type of stone removal, it must first be performed in a safe manner. Because many stone removal may require long-term medication, and in the process of long-term medication medication may cause some liver and kidney damage, which needs to be taken seriously. In addition, lithotripsy is generally not recommended as the primary treatment option for bile duct stones, as it is prone to great complications and sequelae. Generally speaking, the first choice for bile duct stones is to remove the stones by endoscopic retrograde cholangiopancreatography (ERCP) or by surgical excision of the bile ducts, which is relatively safer.
