Abstract
Described herein are methods and devices for performing endoscopic retrograde cholangiopancreatography (ERCP). A system comprising an elongate body housing a front-viewing endoscope and a tissue grasping instrument can be used to facilitate the insertion of a catheter into the ampulla of Vater. The distal end of the elongate body can be positioned such that the operator of the system can view the ampulla while manipulating the surrounding tissue to ease cannulation of the opening with the catheter. As a result, the procedure can be performed faster and more reliably than in the past.
