My daughter has been on a similar "journey" for the past year, only in her case the cause is cndometriosis spread to the bowel and intestines. She is scheduled for surgery in Feb., but in the meantime, she regularly winds up in the ER for pain. And because she is a young woman with a psych history (like your wife, as I read on the report), she is suspected of drug- seeking and basically ignored...But bless you for being a supportive husband. (My SIL, not so much.) Hang in there, and keep fighting for her!
