I have chron's with an ileostomy. i have been having bowel obstructions often that clear up on their own. having upper gi/small bowel series. what happpens if he finds a stricture or adhesion?

Depends: May benefit from surgical lysis of adhesion, or removal/opening of stricture.

Depends: If you have a symptoms with findings on a xray the explains it, treatment would depend on what's causing the stricture...If it is recurrent crohns disease treatment might consist of medical therapy with medication change. Occasionally with an ileostomy a stricture can be treated with balloon dilation and occasionally the best treatment is surgery. If your xray is normal other studies can be done.
