- Accuracy of transabdominal ultrasound in evaluating bowel preparation adequacy before colonoscopy as assessed by the Boston Bowel Preparation Scale (BPPS) [ Time Frame: 4 months ]
The BBPS was developed to limit interobserver variability in the rating of bowel-preparation quality, while preserving the ability to distinguish various degrees of bowel cleanliness. The points are assigned as follows:
- 0 - unprepared colon segment with mucosa not seen because of solid stool that cannot be cleared.
- 1 - portion of mucosa of the colon segment seen, but other areas of the colon segment are not well seen because of staining, residual stool, and/or opaque liquid.
- 2 - minor amount of residual staining, small fragments of stool, and/or opaque liquid, but mucosa of colon segment is seen well.
- 3 - entire mucosa of colon segment seen well, with no residual staining, small fragments of stool, or opaque liquid.
The correlation between ultrasound score and BBPS score will be evaluated.
