Dad had pancreatic surgery 1/16 and just these past two days have vomited?

See a doctor: Hi. What was the pancreatic surgery done for? His vomiting may be related or unrelated to his underlying pathology or consequences from the surgery. We out here in internet-land can't say. He should talk with his doctor, have appropriate tests done, and proceed accordingly. Good luck to him! I hope it's just a GI bug.

I don't know what: your question is and you haven't given enough information. If the vomiting continues, check w/your doctor.
