Ileoanal Reservoir Guide (29 pages) – published by the United Ostomy Associations of America (UOAA). This is an up-to-date (revised in 2018) and very comprehensive guide to J-Pouches. It covers how it works, why it may (and may not) be an option, and what the alternatives are.
Patient & Family Guide to Ileal J-Pouch Anal Anastomosis (IPAA) Surgery (23 pages) – This guide, written by the Colon & Rectal Surgery Division of the University of Pennsylvania Health System, is specifically designed for people who will be having a J-Pouch. But because most of it is about living with and caring for a temporary ileostomy created before the J-Pouch, it’s really more of an intro guide to ileostomies. It’s done in note form, with lots of good photos, so it’s easy to read and understand.
