简要总结
The purpose of this investigation is validate a new bowel preparation scale and to compare it to existing bowel preparation scales.
详细描述
Early studies of bowel preparations for colonoscopy relied on scales to measure the cleanliness of the colon that were not validated or sensitive to differences in preparation quality. Often these scales would simply describe the bowel preparation as adequate or inadequate based on the endoscopist's judgment of quality of the overall preparation.
An ideal bowel cleanliness scale would:
- Produce a score that is reproducible from endoscopist to endoscopist (be validated).
- Be easy for the endoscopist to use.
- Produce a score that is easily converted into the poor/fair/good/excellent subjective rating scale that is often used by gastroenterologists in their colonoscopy reports.
- Produce a score that is easily converted into the adequate/inadequate subjective rating scale that is often used by gastroenterologists in their colonoscopy reports.
- Recognize truly outstanding preparations where 100% of the mucosa is well visualized without any cleaning required.
- Recognize adequate preparations (the ability to visualize the mucosa), but also measure the effort required to clean the colon of residual liquid.
In 2004, a study validating the Ottawa Preparation Scale (OPS) was published (Rostom, Jolicoeur, 2004). A description of the scoring system is below:
Ottawa Preparation Scale (OPS) rating for each colon segment 4=Inadequate (Solid stool not cleared with washing and suctioning) 3=Poor (Necessary to wash and suction to obtain a reasonable view) 2=Fair (Necessary to suction liquid to adequately view segment) 1=Good (Minimal turbid fluid in segment) 0=Excellent (Mucosal detail clearly visible) Ottawa Preparation Scale (OPS) rating for the amount of fluid in the whole colon 2=Lots of fluid

结局指标
主要结局
Correlation coefficient between the PA and physician ratings of bowel cleanliness
时间窗: During a Colonoscopy (about 20 min)
The quality of the colon preparation will be graded based on the OPS, BBPS, an adequate/inadequate scale and our new CBPS. The correlation between the endoscopist's cleanliness rating and the physician assistant's cleanliness rating will be calculated using the appropriate statistical measures. These statistical measures were chosen before the study began by our statistical consultant.
次要结局
- Correlation coefficient between the PA and physician ratings of total bowel fluid.(During a Colonoscopy (about 20 min))
