Complications of choledocholithiasis include bile duct obstruction, secondary infection, and biliary pancreatitis.
1. Bile duct obstruction: choledocholithiasis may lead to bile duct obstruction if it is large in size or due to changes in body position, etc. Bile duct obstruction will cause poor bile drainage and lead to bile stasis, resulting in impaired liver function.
2. Secondary infection: after the obstruction caused by choledocholithiasis, secondary infection may occur and acute obstructive cholangitis may occur.
3. Biliary pancreatitis: stones cause obstruction and stimulation of the lower Oddi sphincter of the common bile duct, which may lead to poor drainage of pancreatic fluid, leading to acute pancreatitis, and in severe cases, severe pancreatitis and life-threatening.
It is recommended to consult a doctor to determine the size and location of common bile duct stones, and the doctor will evaluate whether further treatment is needed.
