preparation failure for multiple colonoscopies
I had two failed preps for follow-up colonoscopies, as part of on going follow-up for colorectal cancer (resection removed tumor, and now involved in extended follow-up). Followed the prep directions to the letter (PEG and one other); both failed and there was initial blame on me for not following directions. Believe me, since I did have a very large, malignant tumor removed, the LAST thing I would do is compromise the bowel prep process. Am set to have my 3rd colonoscopy in 24 hours, and am worried if this one also fails, what options are there for screening?
I am 67 yo, 165lbs, 5'11"; ride a bicycle at 120-150 miles per week at about 16-18 mph. I eat very healthy; was treated for GERD that eventually resulted in a subtotal gastrectomy with roun-y (?spelling?)–ie, stomach has been removed except for a small pouch about the size of a tangerine. What options are available to continue my follow up if this upcoming colonoscopy also fails?
