Fistulotomy as the Primary Cannulation Technique for All Patients Undergoing ERCP: A Randomized, Controlled Trial

Participants in this study will be undergoing a procedure called an endoscopic retrograde cholangiopancreatography (ERCP). This procedure is most commonly performed to help treat conditions affecting specific areas of the digestive system called the pancreas and bile ducts. Patients will consent to allow the study physician to access these areas of the digestive system by either making a cut called a needle-knife fistulotomy or a sphincterotomy.
