Choledochal stones basically require surgical treatment. Choledochal stones can be treated appropriately depending on the number of stones as well as their size. If the choledochal stone is a single stone or 2-3 stones with diameter less than 15mm, transduodenal endoscopy can be chosen to remove the stone. Multiple stones with a diameter greater than 15mm require surgical treatment such as choledochotomy and T-tube drainage. It is suitable for those who have simple common bile duct stones and the upper and lower ends of the bile duct are clear. When the obstruction caused by inflammatory stenosis at the distal end of the common bile duct cannot be relieved, or when the bile duct cannot be reanastomosed due to partial resection of the lesion, then bile-intestinal anastomosis is feasible. The onset of choledocholithiasis is relatively acute, and it is recommended to go to the hospital for treatment under the guidance of a doctor in order to avoid delaying the condition.
