I think that the point is that there is no need for the 6 foot hose any more, not that you do not need further surveillance.
Of course, not only is there no colonoscopy, they do not use a colonoscope. It is a sigmoidoscope, just the short guy. But, whatever you call it, we still need the occasional looky-loo. They keep changing their minds on what is proper protocol, and of course, it should be tailored on your own personal case. Obviously, if you had cancer or even dysplasia, or FAP, you would need closer monitoring than someone who just had colonic inertia and never even had IBD. So, if you have IBD, but no problems, then somewhere in the middle.
