Steve,
I don't have any experience/recommendation regarding the Drs. or hospitals that you mention. However, several of the individuals on the Forum may be able to provide further information.
What type of diversion are you considering? If you haven't made a decision on the type of diversion that you are considering, now's the time. As you can probably image, no doctor can guarantee that you'll be able to receive a more complicated diversion like one of the continent diversions. There are pre-operative considerations that could drive the decision, but there are also issues encountered during the operation that could impact type of diversion. Have you discussed post-operative quality of life issues with both doctors? If you have, are you satisfied with their answers and their commitment to addressing any of your concerns?
If you have made a decision on the type of diversion that you are considering, then an obvious question would be how many types of a particular diversion has each candidate surgeon/hospital performed. If their statistics are similiar, then your decision becomes more difficult, but you might want to consider the support services offered by the hospital. Do they have a specific floor or wing for your recovery?
Will you have a private room? Will family members be allowed to stay with you (beyond normal visiting hours) following your operation? Is one hospital more convenient for your family?
Regardless of your decision, you'll be in our thoughts for a successful operation and full recovery. Please keep us posted and consider participating in one of the weekly chats; the Sunday chat is a very good forum for real time information exchange.
