I had Strictures and I had 5 ENDOSCOPES with 4 Dilations. I am here to say I COULD NOT hold down even Water!!! I had my RNY on July 2, 2013. Right away I started having problems but I thought it was just me learning how much to eat. It felt like the food set on top of my pouch but would go down after awhile. My first ENDO was Nov 2013, Dec 2013, Jan 2014, July 2013. With my last Endoscope and dilation was Jan 2015. I can tell you I NEVER ate anything off my program so it wasn't caused by what I ate. They explained it this way....Strictures are like scar tissue, and we just never know who will have a problem with them. They should have realized that I would be one to suffer with them because it took them 45 minutes to cut thru the scar tissue from past surgeries. So just to clear it up, I couldn't hold down even water.
