Kate- it's in my signature. J Pouch created in 1992. I had dissolving staples, to my knowledge of what my surgeon told me. I am not buying that theory. I have been told by 3 different GIs that its due to backsplash stool and I think they are likely right. The inflammation is also in the neoterminal ileum where the stool is backsplashing- and I have NOTHING at the outlet- which was also stapled BTW. It's backsplash stool and wear and tear on the inlet over 30 years. Should I or anyone else be surprised, no. Of course, that is not any more fixable than the staplers issue. Any J Pouch is gonna backsplash stool as long as it is in your body, because they do not have backsplash valves like our colons did. These are just anatomical facts. And the anatomical facts combine with wear and tear. The same principles require car tires to be changed every 40,000 miles or so.
Just like some tires wear better than others, some 30 year J Pouchers don't have strictures, and they backsplash and had the same staplers. Their pouches perhaps adapted better to dealing with the bad bacteria that pools above the J Pouch inlet.
