Abstract

Application of a new coaxial needle for percutaneous biliary drainage is described. The 22 gauge inner needle is used to select the most appropriate bile duct entry. After cholangiography a 0.018'' guidewire is inserted through the 22 gauge needle. Then a 19 gauge cannula covered with a 5F Teflon sheath is passed coaxially over the 22 gauge needle just into the bile duct. While the 19 gauge cannula is held steady the 5F sheath is advanced over the guidewire. The sheath allows decompression of the ductal system and insertion of a 0.038'' guidewire. Over 50 biliary drainages have been performed successfully with this needle, which is easy to handle, does not require needle exchange, has an optimised length for biliary access, and avoids a secondary 18 gauge needle puncture.
