SECONDARY outcome

Timeframe: 25 minutes

Boston Bowel Preparation Scale (BBPS): scale that rates the quality of the colon preparation based on the amount of stool present. 0:solid stool that cannot be cleared; 1:areas not well seen due to residual stool and/or opaque liquid; 2:small fragments of stool and/or opaque liquid, but mucosa seen well; 3:no residual stool or opaque liquid seen. Score determined by adding the score of each individual segment of the colon (right side, transverse and left side). Scores range from 0 to 3 in each segment, therefore, a total composite score ranges from 0 (poor) to 9 (excellent). Bubble Score (BS): scale that rates the amount of bubbles present in the colon. 0:no or minimal bubbles; 1:bubbles covering up to half the luminal diameter; 2:bubbles covering the circumference of the lumen; 3:bubbles filling the entire lumen. Score determined the same way as BBPS score but in this case a total score of 0 is excellent and 9 is poor.
