question: My mom has hada sudden onset of mottling on her abdomen. I am curious what the cause is. Her back story is as follows: she is 3 weeks post op from a modified Whipple( removed body and tail of pancreas, instead of the head) she went to surgeon s office on a Wednesday to have JP drain removed. Started vomiting about 4-5 hrs after getting home. Continued vomiting until she went to ER sunday. Saturday night her abdomen was normal. Sunday when she was in ER her abdomen now has mottling across the whole thing. I didn t see her surgeon in ER. When I did see him on Monday, I asked about and he has no idea what has caused it. Any ideas????
