Background And Aims:
Single-use/disposable duodenoscopes represent one strategy to decrease the risk of patient infection related to ERCP. A preliminary case series was performed to demonstrate the feasibility and performance of a new single-use duodenoscope in a real-world clinical setting.
Methods:
A single expert endoscopist performed ERCP for standard indications using a single-use duodenoscope.
Results:
Videos of several key steps of ERCP obtained from 4 patients are shown to demonstrate that these steps can successfully be performed using the new single-use device. Clip 1 shows a patient with a large pancreatic duct stone in whom the image quality and maneuverability are demonstrated. Clip 2 shows a patient with choledocholithiasis and demonstrates bile duct cannulation, cholangiography, and sphincterotomy. Clip 3 shows a patient with acute cholecystitis and choledocholithiasis who underwent bile duct cannulation, sphincterotomy, and balloon sweeps. Clip 4 shows a patient with a history of liver transplant and refractory biliary anastomotic stricture who presented with abnormal liver tests and fever and underwent removal of a metal stent and placement of plastic stents.
Conclusions:
A single-use duodenoscope can successfully accomplish fundamental steps of ERCP. This device can potentially eliminate the risk of patient-to-patient infections linked to contaminated instruments. Larger studies are required to assess device performance.
