All are true regarding Barrett's oesophagus except
Epidermal growth factor from saliva is found to be protective against the damage of esophageal mucosa due to reflux based on various studies Duodenogastric reflux increases biliary exposure of lower esophagus and it has been found biliary reflux causes more damage than gastric reflux Decreased clearance of esophagus by peristalsis and retention of acidic contents (lowpH) in lower esophagus causes more damage
Over production of epidermal growth factor from saliva
Decreased esophageal pH
Decreased esophageal motility
Duodenogastric reflux
