I had takedown in March 2014 and I still have these from time to time, especially if I bend over at the waste.  I was told they are due to the numerous open surgeries I had and should subside with time.  

how is your hydration? I have noticed that one of the first places I draw a cramp is at my old stoma site when I have been overly active without proper hydration. I had this happen decades after my surgery. still happens on occasion.

As long as it is relatively fleeting and not constant, it should be OK. This seems likely to be some "kinking" of the intestine due to adhesions (internal scar tissue). The most common site for this is the stoma site. As your gut settles after surgery, this symptom should settle too. More than a year post op you probably as settled as you are going to get. 

Like Dewey said, be sure to stay well hydrated. It does make a difference. Otherwise, surgical release of adhesions are the remedy. Most surgeons don't want to go there, as more surgery may cause more adhesions.
