Symptoms and complications of cholelithiasis result when stones obstruct the cystic duct, bile ducts or both. Temporary obstruction of the cystic duct (as when a stone lodges in cystic duct before the duct dilates and the stone returns to gallbladder) results in biliary pain but is usually short-lived. This is known as cholelithiasis. More persistent obstruction of cystic duct (as when a large stone gets permanently lodged in the neck of the gallbladder) can lead to acute cholecystitis. Sometimes a gallstone may get pass through the cystic duct and get lodged and impacted the common bile duct, and causes obstruction and jaundice. This complication is known as choledocholithiasis
