The oesophagus serves as the vital conduit between the mouth and stomach, and disorders affecting this organ can significantly impact swallowing, comfort, and quality of life. Understanding these conditions enables early recognition and appropriate treatment.
• Gastro-Oesophageal Reflux Disease (GORD)
Understanding GORD
Gastro-oesophageal reflux disease occurs when stomach acid frequently flows back into the oesophagus, causing irritation and inflammation of the oesophageal lining. This common condition affects millions of people worldwide and can range from mild discomfort to severe complications.
Symptoms
The hallmark symptoms of GORD include persistent heartburn, particularly after meals or when lying down, and regurgitation of acid or food. Additional symptoms may include difficulty swallowing, chronic cough, hoarseness, and the sensation of a lump in the throat. Some patients experience atypical symptoms such as chest pain or dental erosion.
Diagnosis
GORD diagnosis often relies on characteristic symptoms and response to treatment. When further evaluation is needed, gastroscopy can assess oesophageal inflammation and complications. Ambulatory pH monitoring provides objective measurement of acid exposure, while barium swallow studies can identify anatomical abnormalities.
Treatment
Treatment typically begins with lifestyle modifications including dietary changes, weight loss, elevation of the head of the bed, and avoidance of trigger foods. Pharmacological therapy includes proton pump inhibitors as first-line treatment for moderate to severe GORD, with H2 receptor antagonists and antacids providing additional symptomatic relief.
Surgery for Gastro-Oesophageal Reflux Disease
Surgical Indications
Anti-reflux surgery is considered for patients with severe GORD who have inadequate response to medical therapy, cannot tolerate long-term medication, or develop complications such as strictures or Barrett’s oesophagus. Young patients requiring lifelong treatment may also benefit from surgical intervention.
Surgical Options
Laparoscopic fundoplication represents the gold standard for anti-reflux surgery. The procedure involves wrapping the upper portion of the stomach around the lower oesophagus to strengthen the lower oesophageal sphincter. Various techniques exist, with Nissen and Toupet fundoplications being most commonly performed.
Outcomes and Considerations
Successful anti-reflux surgery provides long-term symptom control in the majority of patients, with significant reduction in medication requirements. Potential side effects include temporary swallowing difficulties, gas-bloat syndrome, and inability to vomit. Careful patient selection optimises surgical outcomes.
• Barrett’s Oesophagus
Disease Overview
Barrett’s oesophagus develops when chronic acid reflux causes the normal oesophageal lining to be replaced by intestinal-type tissue. This condition is significant because it represents a precancerous change that can progress to oesophageal adenocarcinoma over time.
Symptoms
Many patients with Barrett’s oesophagus have no symptoms beyond those of underlying GORD. The condition is typically discovered during endoscopic examination performed for reflux symptoms. Some patients may experience progressive difficulty swallowing, which could indicate advanced changes or cancer development.
Diagnosis
Barrett’s oesophagus is diagnosed through gastroscopy, which reveals characteristic salmon-pink tissue replacing the normal pale oesophageal lining. Confirmation requires histological examination of biopsy specimens showing intestinal metaplasia. The extent of Barrett’s tissue is carefully mapped to guide treatment decisions.
Treatment
Management focuses on acid suppression to prevent further damage and surveillance to detect dysplastic changes. High-dose proton pump inhibitor therapy is standard treatment. For patients with dysplasia, endoscopic therapy including radiofrequency ablation or endoscopic resection may be recommended. Regular surveillance endoscopy with systematic biopsy sampling monitors for malignant transformation.
