Endoscopic retrograde cholangiopancreatography (ERCP) is an effective technique for diagnosing and treating problems in the liver, gallbladder, and pancreas. The Olympus TJF-Q180V duodenovideoscope, designed exclusively for ERCP procedures and compatible with the new TJF-Q190V Duodenoscope, features a dual guidewire locking mechanism that works with dedicated Olympus V-System endoscopic devices for increased ERCP efficiency.
