What is Choledocholithiasis?
Choledocholithiasis is the presence of a gallstone in the common bile duct. The stone may consist of bile pigments or calcium and cholesterol salts.
Introduction
Bile formed by the hepatocytes about 800~1000 ml per day is important for digesting food intestine, particularly fat. The gallbladder stores and concentrates bile. Bile passes through bile ducts and releases into the intestines when you eat. Choledocholithiasis may form anywhere when there is bile in the gallbladder, cystic ducts, hepatic ducts, and common bile ducts.

Diagnosis
-
Abdominal sonography: the initial diagnostic test of choice in the workup of gallstone disease.
-
CT scan: an excellent method to demonstrate CBD stones, especially those with calcium.

Endoscopic Retrograde Cholangiopancreatography (ERCP): a technique that combines the use of endoscopy and fluoroscopy to diagnose and treat certain problems of the biliary or pancreatic ductal systems.
Treatment
Percutaneous Transhepatic Cholangiography and Drainage (PTCD)
PTCD is a way of examining the bile duct system in the liver. During the exam, a thin needle is inserted through the skin and through the liver into a bile duct. Then dye is injected, and the bile duct system is outlined on X-rays. This procedure is done under local anesthesia by a radiologist.
Before the procedure
do not eat anything 4 hours before the examination
Sign a consent form
After the procedure
The patient should stay in bed for at least six hours after the test, lying on the right side to prevent bleeding from the injection site. The patient may resume normal eating habits and gradually resume normal activities. The doctor should be informed right away if pain develops in the right abdomen or shoulder or in case of fever, dizziness, or a change in stool color to black or red.
Percutaneous Transhepatic Bile Duct Stones Removal(PBSR)
Dilatation of a pre-existing tract created by a previous percutaneous transhepatic biliary drainage (PTCD) procedure is performed, so that the tract can be used to crush and remove the stone inside the gallbladder or in the common bile duct with a basket inserted through the tract.
