title: Insertability and safety of a shape-locking device for colonoscopy.
abstract: BACKGROUND
  Loop formation during colonoscopy insertion results in patient pain and delays in advancement of the colonoscope tip.
  
  
  OBJECTIVE
  To assess the insertability and safety of a novel shape-locking guide (ShapeLock, USGI, San Clemente, CA) that resists looping during colonoscopy.
  
  
  RESULTS
  In 54 patients, both a disposable and a partly reusable version of the ShapeLock received high scores (mean scores >9.0 on 1-10 scale) for ease of insertion, and ability to maneuver the colonoscope through the shape locked device. No significant trauma resulted from use of the device.
  
  
  CONCLUSIONS
  A novel shape-locking device for colonoscopy can be readily and safely inserted into the colon and locked. The device warrants controlled evaluation to determine in which, if any cases, it may be useful for either experienced colonoscopists and/or those with less or minimal experience.
