II. Epidemiology
- Rare conditions, even in specialty centers
 - Peak age of onset >60 years old
 
III. Pathophysiology
- Loss of inhibitory Neuron innervation
- Unopposed excitatory Neuron overactivity within the esophageal Smooth Muscle
 
 - Peristalsis preserved to some extent but is disordered and incoordinated
- Waves of peristalsis occur simultaneously
 - Distal Esophageal Spasm is characterized by premature, forceful contractions
 - Jackhammer Esophagus has properly timed contractions, but increased forceful contractions
 
 
IV. Symptoms
- Sudden, severe Chest Pain in typically brief episodes
 - Patient unable to swallow solids or liquids during the episode
 
V. Differential Diagnosis
- See Esophageal Dysphagia
 - See Chest Pain Causes
 - Exclude Achalasia
 
VI. Evaluation
- See Esophageal Dysmotility
 - Esophageal manometry
 - Esophagram with corkscrew Esophagus
 
VII. Management
- See Esophageal Dysmotility for general measures and overall approach
 - 
                          General Measures
- Offer reassurance
- Functional disorders and Hypercontractile Esophagus improve or resolve spontaneously in a majority of patients
 
 - Optimize GERD Management
- Antisecretory therapy (e.g. Proton Pump Inhibitor)
 
 - Discontinue Opioids
 - Functional Disorders (Hypercontractile Esophagus has significant overlap with functional disorders)
- Stress management
 - Consider Cognitive Behavioral Therapy
 - Consider Antidepressants
 
 - Mindful eating
- Eat smaller, more frequent meals
 - Eat slowly
 - Choose softer foods
 - Avoid foods and situations that trigger symptoms
 
 
 - Offer reassurance
 - Medications
- Precautions
- These medications decrease lower esophageal sphincter pressure and may worsen GERD
 - Smooth Muscle relaxants are best limited to hypermotility confirmed by manometry
 
 - Agents
- Calcium Channel Blockers
 - Nitrates (Nitroglycerin)
 - Phosphodiesterase-5 Inhibitors (release nitric oxide)
 
 - Other agents which are safe and may be effective
- Peppermint Oil (2 mints sublingual before each meal)
 
 
 - Precautions
