"Spray and dye" colonoscopy - any experience of having this?

Hmm I never heard of this. I've had the injected contrast before - never had any issues but the oral contrast gives me D every time. So I would be interested to see if anyone has had this spray too!

It's a recent type of investigation for a particular type of precancer cell if I remember correctly.

I'm assuming your doc will still take biopsies throughout?

Keep us posted as to how it goes for you.

I had this done during my colonoscopy last year. I was in remission at the time and it did not change that status. I had some flat lesion polyps the previous year so he wanted to make sure none remained and the chromoendoscopy allowed him to be more thorough.

Sadly the biopsies are not appreciated by my colon and it takes almost two weeks for things to get back to the pre-colonoscopy state. I just had my yearly colonoscopy last week and although I was in remission beforehand, I had significant bleeding (toilet bowl water deep red) for four days before it stopped. I still have sensations of active inflammation but they usually subside completely after two weeks.

Were your flat lesions adenomas or inflamatory? Did the chromo find anything new?

I reviewed several years of my records and my polyps were noted as either inflammatory or hyperplastic.

I failed to answer the second part of your question so I have edited to add the following information. There were four lesions found in my rectum. The dye makes it much easier to see the flat lesions. I was mistaken in my previous comment in that the flat lesions were found as part of the chromoendoscopy not during the colonoscopy during the previous year.

I'm not sure why he wanted to do a chromoendoscopy because my previous year colonoscopy discovered no polyps but I do have a family history of colon cancer. I asked if he wanted to do it again this year and he did not recommend it.

Here is a quote from my procedure report last year describing the procedure in a little more detail:

Procedure Report said...
This procedure was performed using chromoendoscopy staining for a potentially dysplastic lesion. After initial white examination of the colon, a spray catheter was inserted through the colon and contrast dye was sprayed on the entire surface of the colonic mucosa. A repeat examination of the entire stained colon was performed with the targeted biopsy and removal of the potentially dysplastic lesions. The entire procedure was 40 minutes in duration, to allow additional time required for chromoendoscopy staining, over and above a normal colonoscopy exam.
