Boston Scientific SpyGlass® Direct Visualization System Demonstrates High Procedural Success Rate in Published Study Multi-center study published in Gastrointestinal Endoscopy is largest ever reported on peroral cholangioscopy
NATICK, Mass., Nov. 2, 2011 /PRNewswire/ -- Boston Scientific Corporation (NYSE: BSX) welcomes study results published in the October issue of Gastrointestinal Endoscopy showing an overall procedural success rate of 89 percent for the SpyGlass® Direct Visualization System, a single-operator cholangioscopy (SOC) device. The Boston Scientific-sponsored study followed nearly 300 patients at 15 centers in the U.S. and Europe and is the largest ever to report on peroral cholangioscopy (POC), a procedure that provides imaging and examination of the bile ducts.
Direct visualization of the bile ducts by POC can be valuable in diagnosing biliary abnormalities, obtaining biopsy specimens and guiding stone therapy. Although POC was first introduced four decades ago, adoption was slowed in part by technological limitations of the cholangioscope. The Boston Scientific SpyGlass System was designed to overcome those limitations, allowing physicians to directly visualize the pancreatico-biliary system through a robust, single-operator system permitting use of diagnostic and therapeutic devices while providing color images from a 6,000-pixel fiber optic camera.
Data from the published study show the SpyGlass System technology can be safely used for both diagnostic and therapeutic procedures of the bile duct. In nearly two-thirds of diagnostic cases, procedure results prompted clinicians to make informed changes in disease management. In addition to an 89 percent overall procedural success rate, the study revealed:
- 64 percent of diagnostic procedures resulted in altered patient management
- 88 percent of collected biopsies were adequate for histology
- 66 percent accuracy in identifying a malignancy
- 92 percent procedural success for stone management
- 71 percent of patients achieved complete stone clearance in one session
The study authors conclude that evaluation of bile duct disease and biliary stone therapy can be safely performed with a high success rate by using the SpyGlass System.
"Study results reinforce what I have experienced in my own GI practice," said study author Douglas Pleskow, M.D., Beth Israel Deaconess Medical Center in Boston. "The SpyGlass System is a versatile and beneficial technology for a variety of diagnostic and therapeutic needs in endoscopic procedures. Having direct visual access to the bile ducts and pancreas allows physicians to deliver effective treatment in one procedure, thus improving patient care and potentially reducing costs."
"Findings from this clinical study continue to support previously published data and validate the safety and efficacy of the SpyGlass System as a leading diagnostic and therapeutic endoscopy solution," said David Pierce, President of Boston Scientific's Endoscopy Division. "We are committed to continuously developing innovative treatment options for patients with biliary and pancreatic disease that improve outcomes and advance the standard of care."
Launched worldwide in 2007, the SpyGlass System has been used in approximately 25,000 patient procedures at more than 700 facilities. For more information, visit Boston Scientific's Endoscopy Channel at www.youtube.com/bostonscientificendo.
