Post Gastrectomy Diet

My wife has has had a "J" tube for feeding for the past 20 months.  This was the way of helping her past the removal of her entire stomach due to adenocarcenoma.  That system has failed and she has had the tube removed and will have to make do with not getting 1500 free calories that came with the formula through the tube.  Anyone who can help me with suggestions for her feeding?  We will go home from the hospital this week, where she is being fed intravenously, and be on our own.  Really need input.

Thanks
