Choledochal stone 0.5cm is not that big, if there is no obvious abdominal pain and other clinical symptoms, you can take conservative treatment without surgical removal.
Choledochal stones are one of the most common digestive diseases and can be categorized into primary and secondary stones. Biliary tract infection, bile duct stenosis, and sphincter of Oddi dysfunction are all predisposing factors for choledochal stones. Choledochal stones usually have no obvious symptoms and sometimes only manifest as upper abdominal discomfort.
For asymptomatic choledocholithiasis patients, if the diameter of the stone is <3.5mm, most of the stones can be discharged by themselves without surgical treatment. If the diameter of the stone is more than 3.5mm, it cannot be expelled by itself, but conservative treatment can still be taken, and regular checkups can be performed without surgery.
For symptomatic choledocholithiasis patients, laparoscopic surgery is recommended to remove the stones to prevent them from blocking the bile ducts, causing biliary stasis and even more serious complications. Meanwhile, patients should pay attention to a light diet, eat more foods rich in vitamin A, and undergo regular checkups.
