title: Hood colonoscopy in trainees: a useful adjunct to improve the performance.
abstract: BACKGROUND
  The use of a transparent hood to improve colonoscopic performance has recently been proposed.
  
  
  OBJECTIVE
  The purpose of this study was to evaluate whether using the hood might improve the cecal intubation rate, cecal intubation time, number of attempts needed to intubate the ileo-cecal valve, and polyp detection rate in trainees.
  
  
  METHODS
  Patients undergoing colonoscopy (n = 378) were randomized in two groups, one studied with hood colonoscopy (n = 179) and the other (n = 199) with standard examination.
  
  
  RESULTS
  No differences were found between hood and standard colonoscopy with respect to cecal intubation rate (95 vs 92 %), whereas hood colonoscopy significantly shortened the cecal intubation time, the number of attempts needed to intubate the ileo-cecal valve, and the overall polyp detection rate (p < 0.01 for all these variables).
  
  
  CONCLUSIONS
  Hood colonoscopy might represent a useful adjunct to standard colonoscopy, especially improving the performance of endoscopic trainees.
