The stone was impacted in the distal common bile duct and was crushed with intracorporeal [[lithotripsy]].]] '''Choledocholithiasis''' is the presence of [[gallstone]]s in the [[common bile duct]]. This condition causes [[jaundice]] and [[liver]] cell damage, and is a [[medical emergency]], requiring the [[ERCP|endoscopic retrograde cholangiopancreatography]] (ERCP) procedure or [[surgery|surgical]] treatment. A tendency for this disease can be inherited. ==Cause== While stones can frequently pass through the common bile duct into the [[duodenum]], some stones may be too large to pass through the CBD and may cause an obstruction. ==Complications== This obstruction leads to jaundice, elevation in [[alkaline phosphatase]], increase in conjugated bilirubin in the blood and increase in [[cholesterol]] in the blood. It can also cause acute pancreatitis and [[ascending cholangitis]]. ==Diagnosis== [[Image:CBD stones.JPG|thumb|right|MRCP image of two stones in the distal [[common bile duct]]]] Doctors can use a blood test of alkaline phosphatase, bilirubin and cholesterol to diagnose choledocholithiasis. However, [[ultrasound]] demonstrating an enlarged common bile duct is the test of choice. ==Treatment== Treatment involves removing the stone using ERCP. Typically, the gallbladder is then removed to prevent a future occurrence of common bile duct obstruction. {{Gastroenterology}} [[Category:Gastroenterology]] [[Category:Hepatology]] {{disease-stub}} [[pt:Coledocolitíase]]
