Characteristics of severe forms of gastro-oesophageal reflux disease and risk factors of progression of Barrett’s oesophagus

Abstract

1. To investigate the prevalence of erosive esophagitis and its complication -precancerous disease, Barrett‘s oesophagus, in patients referred to upper diagnostic endoscopy with upper gastrointestinal and/or „alarm“ symptoms. 2. To establish clinical, endoscopic and morphological signs associated with severity of gastro-oesophageal reflux disease. 3. To establish clinical, endoscopic and morphological signs associated with precancerous disease - Barrett‘s oesophagus. 4. To determine morphological alterations of stomach, gastro-oesophageal junction and oesophagus mucosa of different severity of GORD and Barrett‘s oesophagus. 5. To analyse clinical, endoscopic and morphological peculiarities of long and short segments of Barrett’s oesophagus. 6. To investigate risk factors associated with progression of precancerous disease, Barrett‘s oesophagus, during two years follow-up period
