Gastroesophageal reflux (GERD) is consequence of failure of the normal antireflux barrier of the lower esophageal sphincter system Hiatus hernia impairs the function of lower esophageal sphincter and has been implicated as causative factor in patients with severe GERD. Spectrum of GERD varies from mild heartburn with normal endoscopic findings and no esophageal mucosal disease to esophageal ulcerations, bleeding, stricture and dysphagia. Prolonged GERD can lead to Barrett’s esophagus which is risk factor for esophageal dysplasia and cancer
