Undoing the Nissen Wrap

I recently had a Nissen Fundoplication done.  I have been experiencing severe dysphasia to some liquids and most solid foods.   I have had an upper endoscopy done and they said everything looked good internally.  They were supposed to dilate and they did not due to not finding strictures.   Now I am signed up for a barium swallow test, manometry, and gastric empting test.  It seems like they are trying to determine if the wrap needs to come down.

Has anyone had similar problems after a nissen wrap?

Has anyone had wrap taken down?

Did this solve the dysphasia?

I have not eaten solid food in 8 weeks.  I have lost over 20 lbs.  Any info may help...
