Percutaneous transhepatic cholangiography with the ''skinny'' needle. A rapid, simple, and accurate method in the diagnosis of cholestasis
1977
: One hundred thirty-one cases of cholestasis were evaluated by "skinny" needle percutaneous transhepatic cholangiography. The biliary tree was seen in 129 patients (98.5%). When the biliary tree was dilated, a success rate of 100% was obtained. In the 45 patients with nondilated ducts, visualization was achieved in 95.6%. There was no mortality, early operation, or transfusion requirement associated with the procedure. This form of cholangiography is a simple, reliable, and extremely high-yield technique for evaluating patients with cholestasis.
