PURPOSE OF REVIEW: Treatment-refractory gastro-oesophageal reflux disease (GERD) remains a significant problem in the gastroenterology clinic. In recent years, several studies have investigated the assessment and treatment of refractory GERD.
RECENT FINDINGS: Patients presenting with 'refractory GERD' in fact represent a quite heterogeneous group consisting of those with ongoing reflux-related symptoms and those with reflux-unrelated problems such as functional heartburn, dyspepsia or even eosinophilic oesophagitis. The greatest symptom indicators of persistent true reflux are retrosternal burning and acid taste in the mouth alone. Combined pH-impedance studies allow detection of reflux regardless of pH, and weakly acidic reflux has been suggested as a mechanism of residual symptoms in some patients. The use of reflux-symptom association calculations may help to determine the symptom causation, but refinement and outcome studies are needed. New treatments of refractory GERD have been disappointing. Surgery remains an option in very carefully selected patients, but again better outcome studies are required.
SUMMARY: Careful history and investigation is required in the assessment of the proton pump inhibitor (PPI)-refractory patient. Care to exclude alternative diagnoses is needed, and to phenotype those with reflux-related symptoms. Optimization of PPI therapy may help, as may surgery in selected patients.
