A comparison between single-use (A,C,E) and reusable duodenoscope (B,D,F) in terms of the degree of lifting of the elevator with an inserted device. (A,B) represents the procedural cholangiograms of a male patient with a cystic duct syndrome with the SpyScope introduced in the cystic duct in A, and a diagnostic catheter in B. (C-F) represent the procedural cholangiograms of a male patient with chronic pancreatitis and benign distal biliary duct stenosis. C-D reflect the introduction of diagnostic catheter in the main pancreatic duct, while E-F show the insertion of the catheter in the common bile duct
