Video Tutorial and Oral Explanation Vs Oral Explanation Alone in Colonoscopy Preparation

The quality of the colonic preparation is essential for the quality of the colonic examination: in one hand, a good preparation will allow the feasibility of the colonoscopy and will allow a complete examination. On the other hand, the presence of stercoral residues due to a bad colonic preparation reduces the sensitivity of the examination by hiding small lesions or with a very discreet relief. A poorer quality will also increase the length of the examination, which increase the risk of complications. However, in the literature, 20 to 30% of poor colonic preparation is found and 5% of colonoscopies are incomplete, including 42% due to poor preparation. The Pacôme survey, reveals that 6% of patients did not have prior consultation with the gastroenterologist. In addition, if 81% of patients were informed of the importance of the preparation, only 64% were aware of its practical modalities. Only 57% of patients were aware of the risks of inadequate preparation, despite the fact that doctors feel they have well informed their patients. It is also reported in "2 days of endoscopy 2008", that 8% of the information is given by someone other than the gastroenterologist himself. These data demonstrate that there is a heterogeneity in the explanatory content of the consultation prior to the colonoscopy examination. This can then explain the rate of poor quality colonic preparation and consequently the colonoscopy examination. The consultation must be a real therapeutic education and must be sufficiently informative to result in a colonic preparation of quality. We then hypothesize that an informative explanation in the form of a tutorial film would ensure homogeneous and standardized information between practitioners. In addition, the tutorial film will be available to be viewed at home several times by the patient, which may reduce the risk of misunderstanding.
