I didn't need to think about such a surgery, I was only offered a temp. ileostomy because none of the meds worked. Until I found chronic antibiotics to be a solution for me.
Short-chain fatty acids are inside the stool moving through the bowel. They nourish the mucosa. They are also built by some bacteria. It is those fatty acids missing when the last part of the bowel or pouch is disconnected what can cause colitis-like inflammation problems.
