I absolutely would NOT consider a continent or end ileostomy as a solution to end obstructions. ANY further bowel manipulating surgery could result in more adhesions and even more obstructions. Unfortunately, once you are known to be an adhesion former, you always will be.
The only surgery I would consider is repeat lysis of adhesions when necessary. Even that should be a last resort.
You can try restricting very fibrous foods, and increasing fluids, but there is no guarantee that it would help that much (besides sticking with a liquid diet).
Some people use deep tissue massage to break up adhesions, but it seems scary to me.
