Surgeons: if a patient who had a subtotal colectomy w/ileostomy placement 13yrs ago, resulting in short bowel syndrome & frequent loose bowels, but was wanting an ileostomy reversal, what would do & y?

Difficult question: to answer without knowing much more details. Why was that surgery done? What is the remaining anatomy? Remaining colon or rectum in place? Reconnecting an ileostomy after 13 years might not be well tolerated with resulting frequent diarrhea, poor anal muscle control, anal irritation & the surgery would not correct a short bowel condition. Need many more details to try to answer this question.
