[A fine-needle puncture set for percutaneous bile duct drainage (author's transl)].

A new instrument for percutaneous bile duct drainage has been employed on 30 patients with obstructive jaundice. The instrument consists of a 28 cm. long needle of 0.7 mm. diameter placed inside a 15 cm. long Teflon sheath of 1.4 mm. external diameter. This permits fine-needle cholangiography and biliary duct drainage as a single procedure. It causes little trauma and speeds up and simplifies the examination. The instrument is also suitable for transhepatic portal vein puncture.
