Brief Summary:
In France, nearly 1.3 million colonoscopies are performed each year. Colonoscopy is the gold standard in France for colorectal cancer screening in populations at risk. However, it has a number of limitations. The quality of the bowel preparation is a critical step for the successful completion of this examination. The occurrence of interval cancers raises the problem of missed lesions. A literature review showed that there were differences between the endoscopy units on quality standards for bowel preparation. The rate of unprepared colonoscopy is estimated between 20 to 40% . In a recent cohort study, 28% of 2516 colonoscopies had a score of Boston of less than or equal to 6. These colonoscopies generate substantial additional costs to redo colonoscopies, estimated at 35 million euros in 2008. The establishment a predictive score for quality of bowel preparation based on a self-administered questionnaire completed by patients during the pre-colonoscopy consultation, would help identify patients at risk of poor preparation in order to optimize the prescribed preparation in this consultation.

patients undergoing colonoscopy Other: Questionnaire
Self administered questionnaire to evaluate the preparation quality of colonoscopy

Primary Outcome Measures :
  1. Score performance [ Time Frame: within 6 month ]
    score performance to predict a poor bowel preparation (defined by a score of Boston inferior or equal to 7 and / or a segment equal to 1)

Secondary Outcome Measures :
  1. acceptability of questionnaire [ Time Frame: end of study ]
    Acceptability of the questionnaire evaluated by the rate of return of the questionnaires and the rate of well completed questionnaires

  2. Adenoma detection [ Time Frame: within 6 month ]
    adenoma detection rate compared to Boston score
