'''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==

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.
