Generally speaking, surgical treatment is preferred for choledochal stones, and commonly used surgical procedures include choledochotomy and stone extraction combined with biliary T-tube drainage and bilioenteric anastomosis.
Choledochal stones are mainly characterized by clinical symptoms related to choledochal obstruction, including abdominal cramps, high fever, chills, jaundice, etc., and there is a possibility of recurrent attacks.
When complete obstruction of the lower end of the common bile duct causes hepatocellular damage and cholestasis, it can be accompanied by biliary bacterial infections, which will progress to a severe stage where symptoms such as shock, apathy, lethargy, confusion and even coma can occur, posing a serious threat to life.
Therefore, removing the stone through surgery can directly contact the obstructing factor and significantly improve the clinical symptoms caused by biliary obstruction.
