Don't think you need a scope...they don't show small bowel anyway. A CT scan with contrast would do the trick. Fingers crossed for you that your travel can go ahead. Please read your travel insurance very well as if you did need to go into hospital for a SBO and your insurance company found out it was a "pre-existing condition" they may not cover you for any expenses....that being said, some countries don't charge much at all for hospital stays etc.
Best of luck and bon voyage.
