New Methods for Diagnosis and Research PERCUTANEOUS TRANSHEPATIC CHOLANGIOGRAPHY
نویسنده
چکیده
This is an evaluation of percutaneous transhepatic cholangiography, a technique of over eight years' standing, previously considered by many authorities as both unrewarding and dangerous. The value and risks of the procedure have been examined in 20 patients with obstructive jaundice of uncertain origin and in one further patient with a post-cholecystectomy syndrome. The presence and the nature of extrahepatic obstructive lesions was correctly diagnosed in 10 of 11 patients shown to have this cause for jaundice. The failure to obtain cholangiograms in the remaining 10 patients was correctly correlated with the presence of intrahepatic obstructive disease due to hepatitis or primary biliary cirrhosis. The risks of percutaneous cholangiography seem over-rated, biliary peritonitis occurring in under 5% of patients submitted to the procedure.

Grey-scale ultrasonography and percutaneous transhepatic cholangiography in biliary tract disease.
Fifty-one patients with suspected obstructive jaundice and 14 without jaundice in whom disease of the biliary tract was suspected but infusion cholangiography had been unhelpful were examined by grey-scale ultrasonography and percutaneous transhepatic cholangiography and the findings analysed retrospectively. Grey-scale ultrasonography distinguished between obstructive and hepatocellular jaundi...

Direct examination of the biliary tree with endoscopes has been a challenge since endoscopists began performing endoscopic retrograde cholangiopancreatography (ERCP) in the late 1960s. Previously, surgeons had used rigid instruments intraoperatively, which made examination difficult. The first direct cholangioscopy performed by an endoscopist was likely unintentionally done in a patient with po...

Chemical and histological studies are often unable to differentiate chronic extrahepatic obstructive jaundice (due to calculi, neoplasia, or stricture) from chronic intrahepatic obstructive jaundice (caused by primary biliary cirrhosis or by drugs, notably anabolic steroids and phenothiazine derivatives). Oral and intravenous cholangiography are also ineffective when the serum bilirubin is grea...

OBJECTIVE To evaluate the prognosis of different ways of drainage for patients with obstructive jaundice caused by hilar cholangiocarcinoma. MATERIALS AND METHODS During the period of January 2006- March 2012, percutaneous transhepatic catheter drainage (PTCD)/ percutaneous transhepatic biliary stenting (PTBS) were performed for 89 patients. According to percutaneous transhepatic cholangiogra...
