What is the appropriate management for an adult patient with pre-existing respiratory or gastrointestinal conditions presenting with abdominal fluttering sensations accompanied by a cough response?

Management of Abdominal Fluttering Sensations with Cough

The most likely diagnosis is diaphragmatic flutter (van Leeuwenhoek's disease), which requires fluoroscopic confirmation and may necessitate phrenic nerve intervention if medical management fails. 1

Immediate Diagnostic Approach

First, determine if this represents true diaphragmatic flutter versus cough-induced abdominal wall complications:

• Perform diaphragmatic fluoroscopy to confirm high-frequency flutter movements of the diaphragm, which is the definitive diagnostic test for van Leeuwenhoek's disease 1
• Obtain point-of-care ultrasound (POCUS) of the abdominal wall to rapidly exclude rectus sheath hematoma, which can present as abdominal pain and visible changes after coughing episodes 2
• If POCUS suggests hematoma, confirm with CT abdomen—ultrasound has approximately 90% sensitivity for this diagnosis 2

Evaluate and Treat the Underlying Cough

Since cough is triggering or accompanying the abdominal symptoms, address the cough etiology systematically:

• Obtain chest radiograph to exclude pneumonia, malignancy, tuberculosis, bronchiectasis, and interstitial lung disease—approximately 31% will show abnormalities 3
• Perform spirometry with bronchodilator response testing, measuring FEV1 before and after short-acting β2-agonist 3
• Review all medications, particularly ACE inhibitors, which cause cough in up to 16% of patients and may take 26 days to 40 weeks to resolve after discontinuation 4

Address Gastroesophageal Reflux Disease (GERD)

GERD is a common cause of chronic cough and can present without gastrointestinal symptoms in up to 75% of cases:

• Initiate proton pump inhibitors (PPIs) such as omeprazole 20-40 mg twice daily before meals for at least 8 weeks 4
• Add prokinetic agents such as metoclopramide 10 mg three times daily if needed 4
• Eliminate medications that worsen reflux including bisphosphonates, nitrates, calcium channel blockers, theophylline, and progesterones 4
• Cough occurring with eating, postprandially, or with phonation (talking, laughing, singing) strongly suggests reflux as the etiology 4

Manage Upper Airway Cough Syndrome (UACS)

If prominent nasal symptoms, post-nasal drip sensation, or throat clearing accompany the cough:

• Prescribe first-generation antihistamine/decongestant combination as first-line therapy 5, 6
• Add topical intranasal corticosteroids for a 1-month trial if upper airway symptoms are prominent 4
• Second-generation antihistamines are less effective than first-generation agents for non-histamine-mediated post-nasal drip 7

Specific Management for Diaphragmatic Flutter

If fluoroscopy confirms diaphragmatic flutter:

• Attempt medical management first, though specific pharmacologic options are limited 1
• Consider phrenic nerve crush if symptoms remain highly disabling despite medical treatment 1
• Evaluate for recent stroke or neurologic events, as diaphragmatic flutter can occur post-stroke 1

Critical Pitfalls to Avoid

• Do NOT dismiss visible abdominal wall movements as benign—they require fluoroscopic evaluation to distinguish diaphragmatic flutter from other causes 1
• Do NOT use single peak flow measurements for asthma diagnosis—they are less accurate than FEV1 for identifying airflow obstruction 3
• Do NOT prescribe antibiotics for viral upper respiratory infections or post-infectious cough unless bacterial sinusitis or pertussis is confirmed 3, 5
• Do NOT abandon GERD therapy prematurely—it may require 8-12 weeks for response 3
• Do NOT assume normal spirometry excludes asthma or eosinophilic bronchitis 3

When to Escalate Care

• Hemoptysis, fever, night sweats, weight loss, or history of tuberculosis, cancer, or AIDS require urgent expanded workup 3
• In smokers with finger clubbing, pleural effusion, or lobar collapse, strongly suspect bronchogenic carcinoma 3
• If cough persists beyond 8 weeks despite treatment trials, proceed to advanced testing including high-resolution CT chest, 24-hour esophageal pH monitoring, or bronchoscopy 3
• Consider gabapentin trial starting at 300 mg once daily, escalating to maximum 1,800 mg daily in divided doses for refractory cough 3
