I have colonic inertia and like you, constipation got progressively worse over the years. I'm 63 and knew I had to exhaust all the medication routes and whatnot before what I thought might be a colon "resection". As it turned out, because of the pelvic floor problems and whatnot, I had to have an ileostomy. I was to the point that I wasn't having a BM but every 10 days or 2 weeks at which time I was miserable. The sitz marker test showed that what should have gone through my system in 34 hours, took over 135 hours.
I had the surgery on 2.2.17. They left the large bowel/colon in place. I have a loop ileostomy which theoretically could be reversed, but with the pelvic floor issues, I am sure it won't be. I was released after 3 days but had to be readmitted two days later because of projectile vomiting, pain and dehydration... I guess due to an ileus. There were blockages in each bend of the small intestine. The surgeon was concerned that the slow/inertia might also be in the small intestine but it may be because of the time it takes for everything to wake up. Getting everything under control was pretty miserable but two weeks later I was finally able to come home and recuperate. I'm already very happy with the surgery... in fact, I'm astounded to realize what should have been going through my digestive system, including toxins. Likely because of age and whatnot, the recovery is taking a little longer that I originally thought. Still, so grateful to not have to do so many enemas, suppositories etc.. It's quite a learning curve and a new way of life but I'm looking forward to being able to be even more active that I was before the surgery.
I hope you're able to find some relief. I have met some amazing people and have been humbled by the help and support I've received. If I can do even a part of the same for you, I'd be delighted.
