Wraps can look like a hernia, especially if you didn't tell the tech about it or the tech didn't bother to relay that message to whoever read the pictures. The doc you saw may not have even seen the CT personally, only read the report.
Get a copy of the CT on disc. They should give it to you free if you say it's for another doctor. Make a copy for yourself. Take the CD and the report to your regular gastro.
