Fleet Phosphosoda & Colonoscopy Results - Pinworms I can't get rid of

I used the Fleet Phosphosoda laxative on Monday to clean out my colon before a colonoscopy. Is that the same thing as a bowel cleanse? The colonoscopy pictures showed the colon to be light yellow in color. Would that mean that I don't have any mucoidal plaque? I went for the colonsocopy to try to find out why I haven't been able to get rid of pinworms, which I've been treating for 1 1/2 years, including 5 months using Clear & Experience, and several doses of prescription and OTC worm medicine (Vermox & Pin-X). Very frustrating as I followed all the Clear/Experience instructions to a T.

Thanks,
Rose
