barrett's esophagus

Have had 4 endoscopies over the past 4 yrs. Taking PPI...

First one: Positive for Barretts - No Dysplasia
2nd one 1 yr later: Positive for Barretts - No Dysplasia
3rd one 3 yrs after 2nd one: NO Barretts - No Dysplasia
4th one 3 yrs after 3rd one: NO Barretts - No Dysplasia

I did not think Barretts could be cured. Wondering if I have 2 false positives, or 2 false negatives... Any comments?

Next one is scheduled for 3-5 yrs out. (I guess it's my call)

I also have Barretts, with no dysplasia. I have a hiatal hernia, and GERD. I will be having a full Nissan Fundoplication next month. Hoping to heal up and start having a normal life.
