When I read this post the first time I went to google and searched 'ileocecal valve' and I cam eacross bunches of photos, real photos taken internally, of ileocecal valve problems... and, now I could be wrong, but it looked to me like the photos showed excessive waste in the colon causing the ileocecal valve problems. All the photos showed a lot of poop directly behind the valve making it difficult for the valve to stay closed.

Which leads me to wonder if you have ever considered a colon cleanse routine to help resolve these problems. Parasites also seem to be indicated in these situations.
