I am so sorry for what you are going through. I had a very short-term pouch twist. It had twisted up into a hernia and was removed surgically very quickly.
But I have had a lot of blockages due to a loop of bowel that causes problems (adhesions and stuck to the wall).
I bought myself an immersion blender. It is a handheld device that you can put directly into a pot or a jug.
I use it to make smoothies, soups, puréed vegetables and just about anything.
It is a godsend...it has allowed me to keep up my nutrition and eat a large variety of foods.
It is not a solution to the twist...it is just a safer way to eat if you have one.
