Bilateral vocal cord paresis as a rare complication of endoscopic retrograde cholangiopancreatography: a case report for the attention of endoscopist

Vinota Paniselvam, Ahmad Nordin


Bilateral vocal cord paresis is an extremely rare complication of endoscopic retrograde cholangiopancreatography (ERCP) with no case reported prior to this. We present a case of a 38 years old gentleman who suddenly developed aphonia and aspiration symptoms following ERCP. A rigid laryngoscopy done showed adductor paresis of bilateral vocal cords causing his symptoms, which was presumed to be a complication of the ERCP. He was treated conservatively and clinically improved with time. The present case report emphasizes that bilateral vocal cord paresis could occur as a complication of ERCP.
