title: Refinement of ERCP by using the Olympus V-scope system with a 0.025 in. compatible and complete fixable Visiglide(®) guidewire.
abstract: OBJECTIVE
  Prospective evaluation of the new 0.025 in. Visiglide(®) guidewire to facilitate endoscopic retrograde cholangiopancreaticography using the Olympus V-scope.
  
  
  METHODS
  Interventional endoscopic retrograde cholangiopancreaticography was performed in 9 patients with the Olympus V-scope and the 0.025 in. Visiglide(®) guidewire (VS group), whilst 9 other patients underwent endoscopic retrograde cholangiopancreaticography with a conventional Olympus duodenoscope using 0.035 in. conventional guidewires (controls). Exchange time of accessories, X-ray time, dose and endoscopic retrograde cholangiopancreaticography examination time were investigated.
  
  
  RESULTS
  The VS group showed a significantly lower exchange time of endoscopic retrograde cholangiopancreaticography accessories (9; 4-10s, p<0.0001) than controls (29; 19-44s). The Visiglide(®) guidewire was complete fixable by the elevator in 35/36 instrument exchanges (97%) compared to 16/31 exchanges (52%) using conventional guidewires.
  
  
  CONCLUSIONS
  Single-centre study, small patient numbers, two investigators.
  
  
  CONCLUSIONS
  Endoscopic retrograde cholangiopancreaticography using the Olympus V-scope with the new 0.025 in. Visiglide(®) guidewire enables a 3-fold faster exchange of accessories due to a nearly complete fixation of the guidewire.
