I have a hiatial Hernia but I can't have the Nissen Fundoplication (NF)since I have Barrett's Esophagus in the area of the hernia that needs to be monitored. Having the NF would hide the area of Barrett's and wouldn't allow for treatment. There are a # of members here that have had a NF and should give you input. If I remember correctly the most common problem is making the wrap too tight causing difficulty swallowing and burping. I am traveling to Mayo tomorrow for a scope on my Barrett's on Tuesday. Good luck on your problem & hopefully you get a lot of answers.
