Scott is right Dana,
Survival is rare when you hit Gangrene...especially internally...where you cannot see it to treat it...you have been through the trenches here, gangrene, mega doses of pain meds, surgery, resection of your small bowel (and no, they never take just a couple of inches, they do 'safety margins' to make sure that they did not miss anything...usually up to a foot on either side (depends on the surgeon)...Their job is to make sure that the disease does not return, you digestions is someone else's job...
So you are dealing with resection, dehydration (less bowel here to absorb), shock, anesthetic, yet another blockage...you are going to be in pain, sore, exhausted and just plain 'flat' for quite a while...so call in all of those chips & markers that you have out their...Get the neighbors to pitch in with the kids, grandmas if you've got them, friends, family and anyone but the milk man...you need help, now....
You can pay them all back once you are back on your feet but for now, use those that you can, and beg, borrow or steal sympathy and help from those less willing to pitch in...it will do them some good too.
PS...let those kiddies draw pictures on the floor beside your bed, fetch and carry for you and help you with whatever You need...They will stay busy and be thrilled to help mom.
