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.
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.
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]
The following represent indications for ERCP, particularly if or when less invasive options are not adequate or definitive: Fluoroscopic image of common bile duct stone seen at the time of ERCP. The stone is impacted in the distal common bile duct. A nasobiliary tube has been inserted.
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.
The intravenous cholangiogram or IVC is a radiologic (x-ray) procedure that is used primarily to look at the larger bile ducts within the liver and the bile ducts outside the liver. The procedure can be used to locate gallstones within these bile ducts. IVC also can be used to identify other causes of obstruction to the flow of bile, for ...
Oral cholecystography is a radiological procedure used to visualize the gallbladder and biliary channels, developed in 1924 by American surgeons Evarts Ambrose Graham and Warren Henry Cole.
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 ...
