Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to prospectively evaluate the frequency of bacteremia after ERCP/cholangioscopy using the Spyglass Direct Visualization System. In addition, the frequency of cholangitis/sepsis despite use of post procedural antibiotics will be studied.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Rates of bacteremia (bacterial seeding of the blood) following ERCP's range from 6.4% to 18.0%. However, infectious complications of cholangitis/sepsis occur in only 0.5%- 3.0% of patients undergoing this procedure. The Spyglass Direct Visualization System allows cholangioscopy with direct visualization of the bile duct during ERCP by using a specialized small caliber endoscope. During the Spyglass portion of the procedure, saline is introduced into the bile duct to to irrigate the biliary system, in order to distend the biliary ducts and to improve visualization by clearing contrast, pus and stone debris. Saline irrigation may increase intrabiliary pressures and may therefore theoretically increase the risk for bacteremia and infection.

The effect of Spyglass cholangioscopy and biliary irrigation on the frequency of bacteremia/post cholangioscopy infections is unknown and has not previously been studied.

The aim of this study is to prospectively evaluate the frequency of bacteremia after ERCP/cholangioscopy using the Spyglass system.
