Gastro-oesophageal reflux disease (GORD)

Definition

  • Passage of gastric content into the oesophagus due to relaxation of the lower oesophageal sphincter
  • Acid or bile causes mucosal irritation


Aetiology

  • Ineffective lower oesophageal sphincter
  • Hiatus hernia
  • Obesity
  • Alcohol (increased acid secretion)
  • Oesophageal dysmotility
  • Pregnancy
  • Drugs: nifedipine / isosorbide mononitrate


Clinical features

  • Retrosternal burning pain (heartburn)
  • Often during the night or when bending over
  • Associated bitter taste in the mouth
  • Sore throat / dysphonia
  • Excessive salivation (water-brash)
  • Nocturnal cough or bronchospasm (aspiration)
  • Dysphagia (difficulty in swallowing)
  • Peptic stricture


Investigations

  • Trial of antacid / proton pump inhibitor
  • Upper GI endoscopy
  • Oesophageal pH studies and manometry


Management

  • Lifestyle changes: reduce smoking / alcohol
  • Lose weight
  • Antacids
  • Histamine2-receptor blocker, e.g. ranitidine
  • Proton Pump inhibitors, e.g. omeprazole
  • (Laparoscopic) Nissen fundoplication


Complications

  • Peptic oesophageal strictures
  • Barrett's oesophagus
  • Oesophageal adenocarcinoma
