The latest treatment for choledochal stones is still based on surgery, which includes choledochotomy for stone removal, T-tube drainage, bile-intestinal anastomosis, and cholangiopancreatography for stone removal. Choledocholithiasis is a stone located in the common bile duct, i.e. extrahepatic choledocholithiasis, which can cause bile duct obstruction, recurrent episodes of abdominal pain, jaundice, and can cause secondary cholangitis. The treatment is still based on surgical treatment to remove the stones as much as possible and relieve the bile duct obstruction. Choledochotomy and lithotripsy + T-tube drainage is one of the common surgical methods, which is suitable for those with simple choledochal stones and patent lower end of bile ducts without stenosis or other lesions, and can be performed by laparoscopic surgery or open surgery. Bile-intestinal anastomosis, also known as internal bile drainage, is indicated for those who cannot release the obstruction caused by inflammatory stenosis at the distal end of the common bile duct, and who present with dilatation of the common bile duct. It is also indicated in cases of abnormalities at the confluence of the bile duct and the pancreatic duct, and in cases where the bile duct has been partially resected due to a lesion that prevents further anastomosis. Endoscopic retrograde cholangiopancreatography is also routinely performed. It is recommended to consult a doctor in a timely manner for standardized treatment under the guidance of a medical professional.
