MESE: International Study to Evaluate Outcomes and Safety of Patients Undergoing ERCP Using a Single-use Cholangioscope and Single-use Duodenoscope
Study Details
Study Description
Brief Summary
Since its introduction more than 40 years ago, endoscopic retrograde cholangiopancreatography (ERCP) has fundamentally changed the treatment of biliopancreatic diseases. Since late 1970s there have been sporadic reports of nosocomial infections linked to endoscopic procedures, the majority caused by inadequate reprocessing of endoscopes. Infections due to multidrug-resistant organisms (MDROs) however have increasingly become a concern in health care, including in gastrointestinal (GI) endoscopy. Since 2010, reports of individual cases and serial outbreaks of MDRO infections associated with ERCP have been published worldwide. This is because, unlike a gastroscope or colonoscope, the duodenoscope is a complex instrument with unique mechanical features incorporated at the distal tip. This includes a recessed space containing an elevator, a wire cable that moves the elevator, working channel, and most recently, a seal that prevents contamination of the elevator wire channel. This complex design creates hard-to-reach areas that make optimal mechanical cleaning and disinfection difficult. With the aim of overcoming these issues, a single-use duodenoscope (EXALT Model D, Boston Scientific Corporation, Marlborough, Massachusetts, USA) has been developed in the United States of America (USA) and approved by the United States Food and Drug Administration (FDA) for clinical use in December 2019. Different studies evaluating this new device, including randomized clinical trials (RCTs), have already been published, which have confirmed that single-use duodenoscopes represent an alternative to reusable duodenoscopes for performing low-complexity ERCP procedures in experienced hands.
Digital Single Operator Cholangioscopy (D-SOC) using the single use Spyglass DS II (Boston Scientific Corporation, Marlborough, Massachusetts, USA) is a diagnostic and therapeutic modality which allows for direct endoscopic visualization of the biliopancreatic ductal system.
The principal diagnostic indication of D-SOC are bile duct or pancreatic strictures and unclear filling defects, adding direct endoscopic appearance data to biopsy sampling or brush cytology in order to improve the diagnostic yield.
The major therapeutic indication for D-SOC is lithotripsy for difficult biliary and pancreatic stones.
However, cholangioscopy increased the risk of post ERCP cholangitis. Bacteremia was suggested to be specifically related to cholangioscopy in 13.9% of 72 patients, based on serial blood samplings, and to be associated with biopsy sampling and strictures.
For this reason, the recent European Society of Gastrointestinal Endoscopy (ESGE) guideline suggests that patients should be considered to be at high risk for post-ERCP cholangitis when cholangioscopy is performed.
Presently, there are very few clinical reports about technical and clinical outcome of ERCPs performed with single use duodenoscope and there is complete lack of data about efficacy, safety and adverse events of the combination of the new single-use duodenoscope and the Spyglass DS II.
The aim of this multicentric retrospective study was to evaluate the technical success, clinical outcome and rate of adverse events of this procedure.

Outcome Measures
Primary Outcome Measures
- Technical success [6 Months]
Technical success defined as the ability to successfully complete the entire procedure (completed without cross-over to a reusable duodenoscope) with the intended diagnostic or therapeutic maneuvers according to the clinical indication (i.e. stone fragmentation/removal, biopsies from the targeted tissue, etc)
- Clinical Outcome [6 Months]
Numbers of adverse events
