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.
In cases where a patient is not a suitable candidate for surgery, an endoscopic stent can be placed. [111] If this is not possible or successful, a percutaneous transhepatic cholangiogram and percutaneous biliary drainage can be used to visualize the blockage and re-establish bile flow. [112]
However, with gallbladder cancer's extremely poor prognosis, most patients will die within a year of surgery. If surgery is not possible, endoscopic stenting or percutaneous transhepatic biliary drainage (PTBD) of the biliary tree can reduce jaundice and a stent in the stomach may relieve vomiting.
Percutaneous transhepatic cholangiography (PTC): Examination of liver and bile ducts by x-rays. This is accomplished by the insertion of a thin needle into the liver carrying a contrast medium to help to see blockage in liver and bile ducts. Endoscopic retrograde cholangiopancreatography (ERCP). Although this is a form of imaging, it is both ...
Cholecystostomy or (cholecystotomy) is a medical procedure used to drain the gallbladder through either a percutaneous or endoscopic approach. The procedure involves creating a stoma in the gallbladder, which can facilitate placement of a tube or stent for drainage, first performed by American surgeon, Dr. John Stough Bobbs, in 1867.
Other procedures associated with ERCP include the trawling of the common bile duct with a basket or balloon to remove gallstones and the insertion of a plastic stent to assist the drainage of bile. [11] Also, the pancreatic duct can be cannulated and stents be inserted. The pancreatic duct requires visualisation in cases of pancreatitis.
Placement of catheters in the biliary system to bypass biliary obstructions and decompress the biliary system. Placement of permanent indwelling biliary stents. Cholecystostomy : Placement of a tube into the gallbladder to remove infected bile in patients with cholecystitis, an inflammation of the gallbladder, who are too frail or too sick to ...
As an alternative to ERCP, percutaneous transhepatic cholangiography (PTC) may be utilized. Magnetic resonance cholangiopancreatography (MRCP) is a non-invasive alternative to ERCP. [ 56 ] [ 57 ] [ 58 ] Some authors have suggested that MRCP should supplant ERCP in the diagnosis of biliary cancers, as it may more accurately define the tumor and ...
