Advice: If you are going to have an endoscopy to check for Barretts, make sure it's done by a GI specialist who knows what areas to biopsy. I was diagnosed with Barretts after I had an endoscopy by a family practice doctor because I was having stomach pain. One of the biopsies showed Barretts (found early with no pre-cancer cells) so I was referred to a GI dr who prescribed Pantoprazole. After a year, my GI dr did another endoscopy and found no Barretts. He said the dr who did my first endoscopy may have biopsied too close to my stomach and picked up some of those cells in error, meaning I never actually had Barretts, or a year on Pantoprazole may have cleared it up. He said I could wean off the Pantoprazole, but I wasn't able to do so without acid reflex so I'm on the lowest dose available, 20mg. My GI dr said Barretts is monitored so closely it rarely progresses to esophageal cancer. At this point, my GI Dr said I don't need another endoscopy for three years.
