title: Push enteroscopy has a 96% cecal intubation rate in colonoscopies that failed because of redundant colons.
abstract: BACKGROUND
  Performing a complete colonoscopy to the cecum is important for ruling out malignancy and other lesions, but failure rates are significant with a standard colonoscope. A previous study using a push enteroscope for failed colonoscopies had a completion rate of 68.7%.
  
  
  OBJECTIVE
  To improve the cecal intubation rate by using a newer version of a push enteroscope.
  
  
  METHODS
  Retrospective study at first, then a prospective study.
  
  
  METHODS
  Single-center veterans health care system.
  
  
  METHODS
  A total of 47 patients in whom the cecum was not reached with a regular adult colonoscope between January 2007 and December 2010 were included. Those with poor bowel preparation were excluded.
  
  
  METHODS
  Repeat colonoscopy using a new version of a push enteroscope.
  
  
  METHODS
  The rate of cecal intubation and additional pathological findings.
  
  
  RESULTS
  The cecum or terminal ileum was reached in 45 patients (96%). Additional significant pathological findings in the previously unexamined colon were seen in 18 patients (38%).
  
  
  CONCLUSIONS
  Small sample size, lack of comparison with other endoscopes.
  
  
  CONCLUSIONS
  Colonoscopy with a push enteroscope could be advanced to either the terminal ileum or cecum in 96% of patients, which is one of the highest known completion rates in patients in whom colonoscopy failed. Clinical management changed in all patients with additional findings.
