Nope. Colon is at the other end. :>) They go up your behind. Endoscopy is the one where they go down your throat. They do have something new on the market for colonoscopy that my doctor calls 'poop in a box'. It's a kit and you do it at home. You place something in your toilet, go number 2, take out the thing in toilet, pull out the bag, add these drops and tie it up and send it off to provided address. That's it. So much better than the whole colonoscopy process. And very accurate. So, that might be an option. good luck
