Management of Persistent Gastroesophageal Reflux Disease (GERD)

Diagnostic Evaluation

The American Gastroenterological Association recommends upper endoscopy as the first step for patients with inadequate response to proton pump inhibitor (PPI) therapy to assess for erosive esophagitis, Barrett's esophagus, and other structural causes 1, 2
Complete endoscopic evaluation should include inspection for erosive esophagitis (graded according to Los Angeles classification), assessment of diaphragmatic hiatus (Hill grade of flap valve), evaluation of axial hiatus hernia length, and inspection for Barrett's esophagus (with Prague classification and biopsy when present) 1, 2, 3
If endoscopy shows Los Angeles grade B or higher esophagitis or long-segment (≥3cm) Barrett's esophagus, GERD diagnosis is confirmed 2
If endoscopy shows normal findings or LA grade A esophagitis, prolonged wireless pH monitoring off PPI therapy (96-hour preferred if available) should be performed to confirm and phenotype GERD 1, 3

For confirmed GERD with inadequate response to standard-dose PPI, verify that the patient has been taking the PPI correctly (30 minutes before meals) 2
Add personalized adjunctive pharmacotherapy based on symptom pattern, such as alginate antacids for breakthrough symptoms 2 or prokinetics for coexistent gastroparesis 1, 3

If medical therapy fails despite optimization and GERD is confirmed by objective testing, laparoscopic fundoplication and magnetic sphincter augmentation are effective surgical options 2
Transoral incisionless fundoplication is an effective endoscopic option in carefully selected patients 1, 3
For obese patients with proven GERD, Roux-en-Y gastric bypass is an effective primary anti-reflux intervention 1, 3

For patients with functional heartburn or reflux hypersensitivity, consider pharmacologic neuromodulation 2 or referral for hypnotherapy, cognitive behavioral therapy, diaphragmatic breathing, and relaxation strategies 1, 3

Avoid empiric dose escalation without diagnostic confirmation of GERD 2
Do not continue long-term PPI therapy without establishing a definitive diagnosis through endoscopy and possibly pH monitoring 1, 3
Recognize that persistent symptoms may be due to non-GERD causes such as functional heartburn, which requires different management approaches 1
Avoid sleeve gastrectomy in obese patients with GERD as it has potential to worsen symptoms 1, 3
