nor do I know about CA doctors. some ideas, however, to share with you.
first check the master list on this site for a doctor that you can get to. btw, help out by updating with any new info.
second, the longest I ever had a blockage was less than a week. by day five I'm vomiting along w pain and eliminating only liquids. is this the case? if not, how do you know there is still a blockage?
finally, the blockage is in the small bowel (of course) and a regular gi doc should be able to determine what to do. one time I was conveniently in hospital when a blockage occurred. prior to X-ray, which determines blockage location, I drank a barium type solution. it happened to move the blockage along. however, at that time I had a J pouch and another GI doctor managed the situation.
another thought, especially if blockages are a regular occurrence, which hopefully it is not. during the K surgery, from the J, dr. Dietz (then at Cleveland clinic, now at university hospital in Cleveland) also removed extensive adhesions on my small intestines. In the seven years since I went from weekly to very few blockages. point is, at least in my case, there might be a problem that can be resolved.
keep us posted as the more info the better. hope you get this resolved asap! jan
