Management of Dysphagia or Chest Pain with Negative Esophageal Motility Test

Diagnostic Considerations

• The American College of Cardiology suggests that gastroesophageal reflux disease (GERD) is the most likely cause for recurring unexplained chest pain of esophageal origin, which can mimic myocardial ischemia, and may present as a squeezing or burning sensation, often occurring after meals or at night, and can worsen with stress 1, 2, 3, 4
• Upper endoscopy evaluation should be considered when an esophageal cause of chest pain is suspected, with particular attention to obtaining multiple esophageal mucosal biopsies to evaluate for eosinophilic esophagitis, especially important with symptoms of dysphagia 5, 1, 4, 6, 7

Treatment Algorithm

• The American College of Gastroenterology recommends a first-line approach of empiric acid suppression therapy with twice-daily proton pump inhibitors (PPIs) for suspected reflux chest pain syndrome, with a 4-week trial, supported by meta-analyses of placebo-controlled trials (Grade A recommendation) 8, 9, 5
• If symptoms persist despite PPI therapy, consider pH or impedance-pH monitoring to exclude refractory reflux symptoms, which should be performed with the patient off acid suppressive therapy 8, 9, 5, 7
• For functional or non-GERD related symptoms, consider referral to a cognitive-behavioral therapist for patients with recurrent chest pain presentations with no evidence of physiological cause (Class 2a, Level B-R recommendation), as psychological factors such as anxiety, panic disorder, depression, and somatoform disorders may contribute to symptoms 1, 2, 4

Special Considerations

• It is crucial to rule out cardiac causes first, as the morbidity and mortality associated with ischemic heart disease is substantially greater than that of GERD 8, 9

Common Pitfalls

• Failing to adequately rule out cardiac causes before attributing chest pain to esophageal origin can lead to misdiagnosis 8, 9, 3
• Overlooking eosinophilic esophagitis, which requires specific biopsy protocols during endoscopy, can result in missed diagnoses 5, 7
• Neglecting psychological factors that may contribute significantly to persistent symptoms can lead to inadequate treatment 1, 2, 4

Cardiac and Gastrointestinal Evaluation for Chest Pain

Initial Assessment and Diagnosis

• The American College of Gastroenterology recommends a high-dose PPI therapy (twice-daily dosing) for 4-8 weeks as the first-line treatment for suspected reflux chest pain syndrome, with up to 58% of adults with eosinophilic esophagitis presenting with chest pain, and a subset may respond to PPIs 10, 11, 12
• Eosinophilic esophagitis (EoE) affects 1-58% of adults presenting with chest pain and is frequently missed without biopsy, emphasizing the need for esophageal biopsies to evaluate for EoE, especially if EGD was performed without biopsies 11, 12, 13, 14
• British Society of Gastroenterology guidelines highlight that chest pain occurs in adults with EoE even without dysphagia, underscoring the importance of considering EoE in the differential diagnosis 13, 14

Diagnostic Testing

• Ambulatory pH monitoring off medications can be performed if symptoms persist despite 4-8 weeks of twice-daily PPI therapy, to objectively document reflux episodes and correlate with symptoms 10
• Esophageal biopsies from proximal and distal esophagus are crucial to evaluate for EoE, which can present with normal-appearing mucosa, and up to 46% of patients with food bolus obstruction have EoE with normal or subtle endoscopic findings 13, 14

Nutcracker Esophagus Diagnosis and Management

Clinical Presentation

• The American College of Cardiology recommends that chest pain be evaluated for cardiac causes first, as the morbidity and mortality of ischemic heart disease substantially exceeds that of esophageal disorders, with cardiac evaluation completed before attributing chest pain to esophageal origin 15
• The American Geriatrics Society notes that dysphagia occurs in 52.6% of patients, typically for both solids and liquids from onset, suggesting motor rather than mechanical obstruction 16
• The American Academy of Allergy, Asthma, and Immunology reports that the disorder predominantly affects females (63.9%) with a mean age of 54.3 years, though it can occur across the third and fourth decades of life 17

Diagnostic Algorithm

• The American College of Cardiology suggests that once acute myocardial injury is excluded, proceed with gastrointestinal evaluation, including upper endoscopy with multiple esophageal mucosal biopsies from both proximal and distal esophagus to exclude eosinophilic esophagitis 15
• The European Society of Gastrointestinal Endoscopy recommends performing upper endoscopy with biopsies to exclude eosinophilic esophagitis, which can present identically and affects up to 58% of adults with chest pain, with erosive esophagitis found in only 8% of nutcracker esophagus patients 18

Critical Pitfalls to Avoid

• The American College of Cardiology advises against attributing chest pain to esophageal origin without first excluding cardiac disease, with a high clinical suspicion in young to middle-aged adults with chest pain and dysphagia 15
• The British Society of Gastroenterology notes that missing eosinophilic esophagitis is a critical pitfall, with up to 46% of food bolus obstruction cases having eosinophilic esophagitis with normal endoscopic appearance, emphasizing the importance of obtaining esophageal biopsies during endoscopy 18

Central Chest Food Impaction: Evidence‑Based Guidance

Diagnostic Prioritization

• Eosinophilic esophagitis (EoE) is the most common benign cause of central chest food‑impaction sensation, accounting for ≈46 % of cases when biopsies are obtained; therefore it should be the primary diagnostic consideration and urgent endoscopy with six esophageal biopsies (proximal + distal) is recommended at the index procedure. 19

Endoscopic Biopsy Protocol

• Six biopsies from two levels (proximal and distal esophagus) should be taken during the initial endoscopy even if the mucosa looks normal, because ≈46 % of food‑bolus obstructions have EoE with subtle or absent endoscopic findings. 19, 20

Impact of Proton‑Pump Inhibitor (PPI) Therapy

• Current PPI use can suppress esophageal eosinophil counts, potentially masking EoE on histology; therefore PPIs should be documented and, when EoE is suspected, discontinued for at least 3 weeks before endoscopy. Approximately 51 % of patients with EoE achieve histologic remission on PPIs, which underscores the risk of false‑negative biopsies. 19, 20

Definitive Management of Confirmed EoE

• Topical corticosteroid therapy should be initiated immediately after diagnosis (especially when endoscopic signs are present and adequate biopsies have been obtained); maintenance treatment significantly reduces the risk of recurrent food‑bolus obstruction. 19, 20

Post‑Discharge Follow‑Up

• A mandatory outpatient follow‑up appointment before discharge is essential, as lack of follow‑up is associated with higher rates of recurrent admissions for food impaction. 19, 20
