Alternative Colonoscopy Prep: Colon Hydrotherapy (Irrigation)

Hi Everyone. I have a colonoscopy every two years, and as a result, I have built up a very bad intolerance to the oral preps of any kind. I simply cannot keep enough solution down to adequately clean myself out for the procedure.

I have been researching Colon Hydrotherapy (Irrigation) as an alternative to the oral prep for colonoscopy. Has anyone used this method, and how well did it work? Has it become more widely accepted as a prep for colonoscopy than it was a few years ago?

I am only considering this for colonoscopy prep, not as something I would do on a regular basis. My system is in good shape with no flares recently. Thanks in advance for your replies.

I suspect most GI's would be reluctant to endorse this for anyone with existing bowel issues. If you have IBD a colonic irrigation could possibly lead to perforation and the need for emergency colectomy.

I know someone who had an naso gastric tube to administer the prep as they couldn't keep it down.
Last time I didn't keep even one drop down I vomited each sip and than each time I vomited I tasted it again so it kept triggering more and more vomitting after 3-5 rounds I just stopped the prep. but I had not eaten in weeks and was having terrible Ds so my colon was cleared anyway.
For my next scope I will have to have it administered via nasogastric tube as I cannot drink the prep
I could do the tablets but they say they are not good for kidneys. Thankfully I have several years to figure it out😁
