Post-Op Endo- What to look for?

Hey guys,
I am almost 7 months out.  I had an RNY and a full gastrectomy due to a Carcinoid tumor.  My surgeon is 90 miles away in NYC and wants me to have another Endoscope to check for any new tumors in the newly constructed pouch.  I can have the endo done locally and will go to the same Dr. that found the tumor pre-op.
Since he is a gastroent., and not really associated with bariatric surgery, are there any specifics that he should be looking for while I am being scoped?  Having no stomach, should he be able to go through the stoma into the small intestine?

Thanks for your help.

Lou
