Steady performance across all ERCP complexity grades1,2,3,4,5,6,7
EXALTTM Model D case studies*
EXALT Model D is the first marketed single-use duodenoscope for endoscopic retrograde cholangiopancreatography (ERCP) procedures and was found to be usable across all ERCP complexity grades in 1,100 patients from seven trials.1,2,3,4,5,6,7 Explore the case studies and watch the footage below to see how EXALT Model D offered maneuverability, stability, and control in a wide variety of ERCP procedure cases.
ERCP with plastic stent placement*
Dr. Sumit Singla, the Chief of Gastroenterology at Henry Ford Health in Detroit MI, shares his strategy for placing a plastic stent with EXALT D after an attempt with a reusable scope was unsuccessful. Using EXALT offered maneuverability that allowed him to efficiently visualize the ampulla and gain access for a successful plastic stent placement.
Ampullectomy with EXALT™ Model D Single-Use Duodenoscope*
Dr. Bhavesh Shah, Chief of Endoscopy, Director of Advanced Endoscopy at MetroHealth Medical Center, explains how ERCP with endoscopic ampullectomy was performed using EXALT™ Model D in a 78-year-old patient with a polypoid lesion at the ampulla, which pathology diagnosed as tubular adenoma.
