Roentgenography of the bile ducts.

Cholangiography

 

roentgenographic examination of the gallbladder and bile ducts after the introduction (orally or intravenously) of an iodine-containing contrast agent that is excreted with bile. The procedure is not applied in the case of pronounced jaundice. Cholangiography yields a clear picture of the anatomical structure and functioning of the gallbladder and bile ducts; it reveals the presence of calculi, or gallstones (cholelithiasis), inflammatory changes (cholecystitis or cholangitis), and disruption of the emptying mechanism of the bladder (dyskinesia).

Although, as reported above, Y-shaped SEMS are effective and safe in MHS treatment, some possible problems should be discussed: (1) insufficient opening of the central portion of the first stent which can be solved with balloon dilation, (2) inaccurate release of the central open mesh at the hilar bifurcation which can be improved by closing and repositioning the stent, and (3) stent occlusion which can be treated with balloon extraction (in case of sludge or stones), with biliary drainage through percutaneous transhepatic cholangiography or with new plastic or metallic stent placement, or.

Various techniques, including laparoscopic trans-cystic common bile duct exploration, endoscopic ultrasound guided trans-hepatic ERCP, laparoscopic choledochoduodeonoscopy, percutaneous transhepatic cholangiography, balloon enteroscopic ERCP, and laparoscopic transgastric ERCP (LTER-CP), are used to access the biliary tree in patients with altered gastrointestinal anatomy (6).
Percutaneous transhepatic cholangiography showed stent occlusion.
Patients under went trans-abdominal ultrasonography, computed tomography, endoscopic retrograde cholangiopancreatography with or without percutaneous transhepatic cholangiography and magnetic resonance imaging as required.
The choices of treatment methods of biliary casts are quite varied and includes choledochoscope, ERCP and percutaneous transhepatic cholangiography drainage.
Medical College, Udaipur, the present study was undertaken to know the cause, site and extent of biliary tract obstruction with the help of various investigations especially ultrasonography, CT scan and percutaneous transhepatic cholangiography (PTC): extent of liver damage through biochemical tests and feasibility of surgery.
Patients with jaundice due to irresectable hilar cholangiocarcinoma underwent percutaneous transhepatic cholangiography (PTC) and biliary stenting as the initial procedure, while those with bile duct obstruction below the hilum had endoscopic retrograde cholangiopancreatography (ERCP) and stenting as the initial procedure.
(8) Percutaneous transhepatic cholangiography (PTC) also has the potential to both diagnose and treat biliary disease; however, it, too, suffers from significant morbidity and mortality--up to 2.5% of patients.
Known today as percutaneous transhepatic cholangiography (PTC), this procedure successfully demonstrates the biliary ducts, but requires passing a needle through the abdominal wall into the liver.[3]
Different diagnostic tools are available for preoperative imaging, all with their own strengths and weaknesses: endoscopic retrograde cholangiography (ERC), magnetic resonance imaging (MRI) with cholangiography (MRC), computed tomography (CT), or percutaneous transhepatic cholangiography (PTC) [10].
