GERD is a condition which develops when the reflux of stomach content causes troublesome
symptoms and / or complications
Esophageal Syndromes
Extra-esophageal Syndromes
Symptomatic Syndromes
• Typical reflux syndrome
• Reflux chest pain syndrome
Syndromes with Esophageal Injury
• Reflux esophagitis• Reflux stricture• Barrett's esophagus
• Adenocarcinoma
Established Association
• Reflux cough
• Reflux laryngitis
• Reflux asthma
• Reflux dental erosions
Proposed Association
• Sinusitis• Pulmonary

• Acid Reflux Symptoms– Abnormal acid exposure– Hypersensitive [(+) S-R correlation]
• Non-acid Reflux Symptoms– Volume refluxers– Hypersensitive [(+) S-R correlation]
• Overlap between well-controlled GERD and Functional Esophageal Disorder
• Do Not Have Reflux at ALL – Functional heartburn….or just functional– Unrelated disease (EoE, EMD, Cardiopulm etc..)
PPI Non-responders are Heterogeneousg EGD n

Gut-directed HypnotherapyAre you getting sleepy?
• Deep physical relaxation and deep mental concentration
• Alters focus of attention, changes meaning about sensations arising from the gut and encourages body to restore itself to a healthier state
• Shown to produce cognitive change and improve pain tolerance
• Modifies physiological arousal and hypersensitivity over long-term
• Initially performed in a doctors office but can eventually be self-guided
• The most scientifically supported non-drug treatment for Functional GI disorders

GERD: Pitfalls
• Patients may have a good response to PPI and not have GERD.
• Patients may have a positive pH study and not have GERD.
• Patients may have a good symptom correlation on pH-impedance testing and not have GERD.
• Be careful with belching, regurgitation and nausea/vomiting.

Gastroesophageal Reflux Disease Conclusions
•Reflux testing is essential to phenotype the patient based on mechanism.- Refractory reflux- Reflux sensitivity- Functional heartburn- Alternative diagnosis- HRIM is extremely
helpful

Gastroesophageal Reflux Disease Conclusions•Phenotype will dictate therapies- Refractory reflux• Endoscopic/surgery
- Reflux sensitivity•Motility agents, TCA, HYPNOSIS
- Functional heartburn• TCA, CBT, Hypnosis
- Rumination syndrome/supragastric belching• Biofeedback, CBT, hypnosis
