Sunday, May 2

  • Holmium Laser Lithotripsy Under Direct Cholangioscopic Guidance in Complicated Stone Cases: Long Term Experience (Poster Presentation featuring SpyGlass System)

This study, led by Bryan G. Sauer, M.D., found that laser lithotripsy using the Holmium laser under cholangioscopic guidance is safe and effective for treating complex biliary stones.

  • Does Contrast Affect Cholangioscope Image Quality? (Poster Presentation featuring SpyGlass System)

This multi-center study, led by Jeffrey T. Laczek, M.D., suggested that cholangioscope image quality is not different when immersed in normal saline, contrast or a mixture of normal saline and contrast, and that endoscopists should use intraductal contrast prior to cholangioscopy if needed for lesion localization.

  • SpyGlass Peroral Cholangioscopy System for Visual Differentiation and Optically Guided Tissue Sample Biopsy of Biliary Strictures: A Single-Center Preliminary Observational Study  (Poster Presentation featuring SpyGlass System)

This study, led by Dimitrios Xinopoulo, M.D., found that the SpyGlass System is a useful diagnostic tool when dealing with radiologically evident biliary strictures, and that tissue sampling under visual control is technically feasible and clinically safe.  

  • Cholangioscopic Characterization of Dominant Biliary Strictures in Patients With Primary Sclerosing Cholangitis (PSC) May Not Be Indicative of Malignancy  (Poster Presentation featuring SpyGlass System)

This study, led by Kalpesh K. Patel, M.D., demonstrated that dominant biliary strictures in PSC patients can be successfully visualized with the SpyGlass System, and adequate tissue can be acquired for biopsy sampling.

  • A Novel Biopsy Protocol for Assessment of Neosquamous Epithelium After Radiofrequency Ablation of Barrett's Esophagus With High Grade Dysplasia (Poster Presentation featuring Radial Jaw 4)

This study, led by Srinadh Komanduri, M.D., found that tissue acquisition with jumbo biopsy forceps facilitates assessment for buried glands after radiofrequency ablation.

  • Randomized Controlled Trial of Two Types of Biopsy Forceps for Polypectomy of Small Sessile Colorectal Polyps (Poster Presentation featuring Radial Jaw 4)

This study, led by Peter V. Draganov, M.D., demonstrated that Radial Jaw 4 Forceps are more effective for complete eradication of small sessile colorectal polyps than Radial Jaw 3 forceps.

Monday, May 3

  • The Utility of New Jumbo Biopsy Forceps for Tissue Acquisition of Gastric Subepithelial Masses (Oral Poster Presentation featuring Radial Jaw 4)

This study, led by Srinadh Komanduri, M.D., demonstrated the efficacy and safety of jumbo biopsy forceps in obtaining diagnostic tissue in gastric subepithelial masses, resulting in cost savings by reducing unnecessary referrals for endoscopic ultrasound and endoscopic surveillance.  Dr. Komanduri will present results of the study from 9:06 - 9:18 a.m.

Tuesday, May 4

  • Endoscopic Stenting Versus Surgical Gastrojejunostomy for Management of Malignant Gastric Outlet Obstruction: Comparison of Clinical Outcomes and Hospital Costs (Podium Presentation featuring WallFlex® Duodenal Stent)

This study, led by Shyam Varadarajulu, M.D., found that endoscopic stenting is associated with lower costs and shorter hospital stays than surgical gastrojejunostomy, which is considered the current gold standard for the relief of malignant gastric outlet obstruction.  Dr. Varadarajulu will present results of the study from 4:36 - 4:48 p.m.  The Company plans to issue a press release at that time.

The SpyGlass System is a single-operator system developed to overcome the challenges of traditional cholangioscopy systems and reduce the need for exploratory surgery. The SpyGlass System is designed to enable physicians to directly visualize the target site, obtain a diagnostic tissue sample with the disposable SpyBite® Biopsy Forceps, and deliver therapies such as laser and electrohydraulic lithotripsy.  The SpyGlass System can be used to guide visualization and accessory devices throughout the pancreatico-biliary system.  Accessory devices can be used to diagnose and treat diseases such as cholangiocarcinoma, pancreatic cancer or pre-cancerous tissues.  To date there have been more than 50 clinical studies published or presented on the SpyGlass System, and more than 15,000 cases have been performed with the device in the U.S. and Europe.

Radial Jaw 4 Biopsy Forceps are designed to enable collection of large, high-quality tissue specimens without the need to use large channel therapeutic endoscopes.  Acquiring tissue for diagnosis is the most frequently performed procedure by gastroenterologists, with approximately 7.15 million biopsy procedures performed in the U.S. in 2008(1).

The WallFlex® Duodenal Stent is a large diameter, radiopaque, flexible self-expanding metal stent designed to help maintain luminal patency in patients with gastroduodenal obstructions.  This stent has atraumatic looped ends and incorporates a flared design intended to reduce the risk of migration.  The low profile, reconstrainable delivery system features a tapered tip to support access and radiopaque markers to aid in placement accuracy.

The SpyGlass Direct Visualization System, Radial Jaw 4 Biopsy Forceps and WallFlex Duodenal Stent will be available for demonstration at Boston Scientific's booth (#935) at DDW.  The Company will also offer hands-on demonstration sessions in its Simulated Clinical Endoscopy Suites and at its booth.
