Asa, I’m sorry you got disappointing news. After 21 years with UC colon cancer (and precancerous lesions) are very common. Others can recommend surgeons in the Connecticut/NYC area. I’d like to reassure you that for most J-pouchers with healthy pouches there is generally no urgency to find a toilet unexpectedly. Since my surgery I have taken up scuba diving, which is about as far from an accessible toilet as you can get. Good luck!
