The diagnosis is confirmed with either a magnetic resonance cholangiopancreatography (MRCP), an endoscopic retrograde cholangiopancreatography (ERCP), or an intraoperative cholangiogram. If the patient must have the gallbladder removed for gallstones, the surgeon may choose to proceed with the surgery, and obtain a cholangiogram during the surgery.
Cholangiography is the imaging of the bile duct (also known as the biliary tree) by x-rays and an injection of contrast medium. [1] Types.
Biliary atresia requires urgent surgical intervention with intraoperative cholangiography. [4] A hepatoportoenterostomy (HPE) procedure is performed to restore the flow of bile from the liver to small intestine. [12] Neonatal cholestasis caused by alpha-1 antitrypsin deficiency does not have any specific treatment. Instead, children with alpha ...
Percutaneous transhepatic cholangiography, percutaneous hepatic cholangiogram (PTHC) is a radiological technique used to visualize the anatomy of the biliary tract. [1] A contrast medium is injected into a bile duct in the liver , after which X-rays are taken.
MRCP has been slowly replacing endoscopic retrograde cholangiopancreatography (ERCP) as investigation of choice. MRCP is highly accurate in diagnosing the biliary system, pancreatic duct and accessing surrounding solid organs.
CBDS are found in 10–15% of patients during cholecystectomy when intraoperative cholangiography (IOC) is routinely performed. [31] [32] There are several strategies to manage choledocholithiasis but the optimal method as well as the timing of treatment is still under debate. [33]
Endoscopic retrograde cholangiopancreatography (ERCP) is a technique that combines the use of endoscopy and fluoroscopy to diagnose and treat certain problems of the biliary or pancreatic ductal systems.
Failure of gallbladder visualisation during oral cholecystography when abnormal liver function returns to normal, or there is mild to moderate liver disease, maybe due to extrahepatic (outside the liver) causes. [4] Oral cholecystography can have better sensitivity and specificity in diagnosing acute and chronic gallbladder disease than ultrasound.
