I am scheduled for endoscopy appointments every six months. My prep for pouch scopes and previously for colonoscopy procedures: Soft foods three or four days in advance, such as fish, egg, tofu. Foods that are easily digested and pass through cleanly. No red meat, or seeds or grains, no corn or peas, no insoluable food. Twenty four hours before the procedure I have only clear liquids and clear broth. No cranberry juice or anything with colour. I bring a thermos of warm broth so I can have something to drink right after the procedure when I am usually loopy and tired (I always ask to be sedated for endoscopy or any procedures happening back there!) I try to ease back into solid food afterward. Good luck. I hope your results are clear.
