Barretts oesophagus

Hi, just had colonoscopy. The endoscopic diagnosis was Barrett's oesophagus-potential microsegment. Does anyone know what this means. I'm waiting to speak with my consultant to find out more. Just a bit worried, as you do...

I know this is 3 months old, did you get a biopsy done?  That wil corfirm if you have Barretts or not.  You should know by now, if not please reply so I can advise. ;-)
