Loop formation during colonoscopy insertion results in patient pain and delays in advancement of the colonoscope tip.
Dr Rex and colleagues assessed the insertability and safety of a novel shape-locking guide (ShapeLock, San Clemente, California) that resists looping during colonoscopy.
The researchers used both a disposable and a partly reusable version of the ShapeLock in 54 patients.

Both the disposable and reusable version of ShapeLock received high scores or mean scores of more than 9 on a scale of 110.
The research team allocated scores for ease of insertion, and ability to maneuver the colonoscope through the shape locked device.
The team reported that no significant trauma resulted from use of the device.
Dr Rex’s team concluded, “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.”
