Absolutely yes Vanessa.
After suffering miserably in the "care" of my local so-called expert GI for 6months post takedown, I got myself to Dr. Shen. Dr. Shen figured out what was wrong with my pouch almost immediately.
But you really must prepare for his visit. You should have your records and tests all sent in advance as well as hand carry them with you. Hopefully you can bring somebody with you. He is a very fast thinker and sometimes is hard to understand. As you have a lot of problems and complicated history, having someone with you to help decipher and process would be advantageous. Also be sure to schedule an extra day(s) there so he has time to scope and do other tests he may deem necessary. And start working on your list of questions.
pm me if I can guide you any more in the CC and preparing for your appt. with Dr. Shen.
