In difficult cases like this, when different doctors give different opinions, it means that there is unlikely to be one right answer.
I cannot give further comment without examining the case. It is possible that the surgery is associated with the gastroparesis.
There are medications like Reglan or Cisapride (not available in the US) which may be of help.
More experimental therapies like gastric pacemakers have been used with variable success.
These options can be discussed with your personal physician or in conjunction with another GI opinion.
Followup with your personal physician is essential.
