Your surgeon at Mayo should be able to determine how much small intestine is left and whether a third pouch can be constructed. A definite diagnosis of Crohns may make construction of a j pouch or a BCIR unadvisable. In some cases, the current j pouch can be re-used to make a BCIR. Please send me a PM if your husband might be considering a BCIR as a option to an ileostomy and would like more information about it.
