z-line barretts

with the finding of z-line barretts in a a short salmon-colored segment with sliding hiatal hernia, having biopsied in each quadrant of the gastro-esophageal junction and same per each 1 cm of a 2 cm segment, with findings of goblett cells only at the GEJ, what is the lilklyhood that the sliding hernia introduced gastric cardia tissue with concomittant goblett cells at the z-line causing  the pathologist to infer barretts, without barretts (other than its clinical determination) actually, per clearly definable histology representative of esophageal  as opposed to gastric tissue, being positively determinable?  What percentage of the the total set of pathology proven barretts esophagus are strictly z-line compared to biopsy proven short and long segment barretts?
