Endoscopic ultrasound (EUS)-guided biliary drainage via either gastrohepatostomy or choledochoduodenostomy are accepted and widespread procedures when endoscopic retrograde cholangiopancreatography (ERCP) fails. EUS guidewire insertion through a 19-G needle into a dilated biliary system is usually a straightforward maneuver. The drainage difficulty begins when the enterobiliary tract has to be dilated over the guidewire to allow the passage of the stent [1]. For this purpose, several dilation devices have been described; some of them employ electric current and others take advantage of the small tip of the device. Initial attempts to enlarge the enterobiliary tract with dilation balloons may fail due to a lack of sufficient stiffness in the tip of the balloon catheter or the inability to inflate the balloon in the middle of the tract. Therefore, another more rigid device needs to be employed prior to balloon dilation. In these situations, we have found the use of a cold needle-knife, without exposure of the wire or use of the electric current, to be helpful.

A 45-year-old man presented with jaundice due to carcinoma in the head of the pancreas and liver metastases. ERCP drainage failed because of disease infiltration into the papillary area. EUS-guided choledochoduodenostomy was attempted. After passing a 0.035-inch, straight-tip, guidewire (Jagwire, length 450 cm; Boston Scientific, Natick, Massachusetts, USA) into the common bile duct through a 19-G needle ([Fig. 1]), several devices were unable to follow the guidewire from the duodenal bulb to the common bile duct lumen. Therefore, a needle-knife papillotome (RX Needle Knife XL, triple lumen; Boston Scientific) with a 5.5-Fr tip (1.8 mm), was pushed firmly over the guidewire, traversing the duodenal and bile duct walls. After removing the needle-knife, a 7-Fr, 7-cm long, plastic biliary stent (Advanix; Boston Scientific) was inserted ([Fig. 2]). The plastic stent was exchanged 5 weeks later for a fully covered self-expanding metal stent, using a duodenoscope and following balloon tract dilation ([Fig. 3] and [Fig. 4]).
