Abstract
RECENT reports from Japan describing percutaneous transhepatic cholangiography (PTC) with a new, thin needle have suggested this technique to be unusually reliable and safe.1We have performed PTC with the "Chiba needle" in 40 patients with suspected biliary tract obstruction or jaundice of uncertain cause. Procedure The needles used in this procedure were developed at Chiba University, Chiba, Japan. This very flexible needle with stylet is made of steel, 15 to 17 cm long and 0.7 mm in diameter.
