Clinical Trial Summary

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.

Clinical Trial Description

The ERCP procedure enables the study doctor to examine regions of the digestive system called the pancreas and bile ducts. After a patient is sedated, a bendable tube with a light (called an endoscope), is inserted through the mouth and into the digestive system. Within the digestive system, the doctor is able to identify the opening to where the gallbladder drains into the small bowel called the ampulla. Using the endoscope, a small plastic tube is then placed in the opening and dye (also called contrast material) is injected into the bile duct (area where bile leaves the liver). X-ray pictures can then be taken to provide further information to the doctor. During the procedure, it is necessary to make a cut to enlarge the opening to allow easier removal of stones from the bile duct or to place plastic tubes (stents) in the bile duct. To make this cut, there are two different approaches that the doctor can take: 1. The standard way of making the cut is referred to as a "sphincterotomy". Using this method, a heated metal wire cuts the opening to the bile duct after a wire has been passed into it. 2. The second way of making the cut is referred to as a "pre-cut". There are various types of "pre-cut" techniques; the technique being evaluated in this study is called the "needle knife fistulotomy". When using this technique, the doctor makes a cut directly into the bile duct using a tiny knife called a "needle knife". Currently, the doctor determines which cutting technique to use. The decision is entirely up to the individual doctor. The purpose of this study, called a randomized, controlled trial, is to compare the safety and effectiveness of the two different approaches to the ERCP. This type of study involves a large number of participants and the results may answer the question as to which approach should be used for patients having the ERCP procedure. The results may change the standard way that doctors conduct this procedure. ;
