A 47-year-old man was diagnosed with chronic pancreatitis and stones in the main pancreatic duct. The patient was referred to our hospital with an enlarged pancreatic pseudocyst caused by a pancreatic stone and obstructive jaundice due to bile duct compression. Endoscopic retrograde cholangiopancreatography was performed for main pancreatic duct stenosis and obstructive jaundice. However, tapered cannulas and conventional stenosis-dilating devices cannot pass beyond the stenosis because of severe stenosis of the pancreatic duct. Therefore, we used a new drill dilator that does not require a pushing operation. The main pancreatic duct was straightened and passed over the stenosis without resistance by rotating the handle clockwise. We successfully implanted 5 Fr pancreatic duct and 7 Fr bile duct stents. Here, we describe a case in which a novel drill dilator was used for the dilatation of a severely stenotic main pancreatic duct with stones.
