Hoarseness After Endoscopic Retrograde Cholangiopancreatography

Question: An 84-year-old man presented with obstructive jaundice owing to an ampullary tumor. An endoscopist, with about 1500 endoscopic retrograde cholangiopancreatography (ERCP) experiences, performed ERCP using a duodenoscope (JF260V, Olympus, Tokyo, Japan) under conscious sedation with 3 mg of midazolam and 15 mg of pentazocine. The duodenoscope was inserted into the duodenum without any issues, such as false insertion into the trachea. After cholangiopancreatography, intraductal ultrasound examination of the bile duct, ampullary biopsy, bile and pancreatic juice cytology, and placement of plastic stent in the bile duct were performed.
