What are the treatment options for esophageal spasms?

Treatment Options for Esophageal Spasms

The most effective treatment approach for esophageal spasms includes pharmacological therapy with smooth muscle relaxants, neuromodulators, and endoscopic botulinum toxin injections, with surgical interventions reserved for refractory cases. 1, 2

Pharmacological Management

First-Line Medications

• Smooth muscle relaxants are effective initial treatments for esophageal spasms:
  • Calcium channel blockers (e.g., diltiazem 60mg three times daily) can provide symptomatic relief in selected patients 3
  • Nitrates (both short and long-acting) help relax smooth muscle of the esophagus 4
  • Baclofen (a GABA-B agonist) may be effective for regurgitation and belch-predominant symptoms, though it can cause CNS and GI side effects 1

Neuromodulators

• Low-dose antidepressants are effective for treating esophageal hypersensitivity and spasms:
  • Serotonin reuptake inhibitors have shown significant improvement in patients with diffuse esophageal spasm 5
  • Tricyclic antidepressants and SSRIs can be used as visceral analgesics to reduce pain perception 4
  • These medications are particularly beneficial when esophageal hypervigilance and visceral hypersensitivity augment symptom burden 1

Endoscopic Interventions

Botulinum Toxin Injection

• Botulinum toxin (BTX) injection is the best-studied treatment option for diffuse esophageal spasm 2
• The procedure involves:
  • Endoscopic injection of 100 IU BTX diluted in saline solution
  • Multiple injection sites along the esophageal wall beginning at the lower esophageal sphincter and moving proximally at 1-1.5 cm intervals 6
• Clinical outcomes show:
  • Immediate symptom improvement in approximately 78% of patients
  • Significant decrease in symptom scores after treatment 6
  • Effects may last 6-24 months, with successful retreatment possible when symptoms recur 6

Endoscopic Dilation

• Esophageal dilation can be considered for patients with associated strictures or narrowing:
  • Balloon dilation or bougie dilators guided by wire are the preferred methods 7
  • Dilation should be performed with caution and typically limited to incremental increases in diameter 7

Surgical Options for Refractory Cases

• Per-oral endoscopic myotomy (POEM) should be considered the preferred treatment for type III achalasia and may be beneficial in select cases of distal esophageal spasm 1
• Heller myotomy with fundoplication remains an alternative for rare refractory patients who have failed other treatment modalities 4
• Surgical approaches should be reserved for patients with severe symptoms that are refractory to pharmacologic and endoscopic treatments 4

Behavioral Interventions

• Cognitive behavioral therapy (CBT), esophageal-directed hypnotherapy, and diaphragmatic breathing can be effective for esophageal disorders with associated hypervigilance or hypersensitivity 1
• These treatments are typically administered by clinical health psychologists or mental health professionals with specialized training in treating chronic GI disorders 1

Diagnostic Considerations Before Treatment

• High-resolution manometry (HRM) is essential for accurate diagnosis and classification of esophageal motility disorders before initiating treatment 1
• HRM can differentiate between:
  • Distal esophageal spasm
  • Achalasia (types I, II, and III)
  • Hypercontractile esophagus 1
• Additional testing may include:
  • Ambulatory impedance-pH monitoring to rule out GERD as a contributing factor 1
  • Endoscopy to exclude structural abnormalities 1

Treatment Algorithm

1. Initial approach: Trial of smooth muscle relaxants (calcium channel blockers or nitrates)
2. If inadequate response: Add or switch to neuromodulators (antidepressants)
3. For persistent symptoms: Consider endoscopic botulinum toxin injection
4. For refractory cases: Evaluate for surgical intervention (POEM or Heller myotomy)
5. Adjunctive therapy: Behavioral interventions for associated psychological factors

Pitfalls and Caveats

• Ensure accurate diagnosis before initiating treatment, as symptoms can mimic other conditions like GERD or cardiac disease 1
• Monitor for side effects of medications, particularly CNS effects with baclofen and antidepressants 1
• Botulinum toxin effects are temporary and may require repeated injections 6
• Surgical interventions should be performed at specialized centers with expertise in esophageal motility disorders 1
