gastrogafin? what mechanism? gastrogaffin is HIGHLY water soluble which is why you get such poor images with it. as soon as it is infused it dilutes out?

aortic aneurysm in the stomach? you mean an abdominal aortic aneurysm? maybe there is a damaged nerve or the graft is compromising some arterial outlet. an aretriogram would show vascular cmpromise and a barium study woudl show level of problem. if either show block at level of aneurysm he may need a gastrectomy or bowel ressection eventually. maybe putting a jejunostmy feeding tube letting the upper bowel rest for a while then seeing if function returns would work?
for now TPN and NG suction is all you can do since there is no way to speed up bowel recovery.

that is my take based on my limited knowledge base. anyone else?

and the answer is E
