Background
- Inability of LES to relax and loss of normal peristalsis [1]
Clinical Features
- Dysphagia
- Regurgitation
- Chest pain
- Esophageal spasm can feel like tight, crushing retrosternal pain similar to ACS
Differential Diagnosis
- Ingested foreign body
- Esophageal carcinoma - dysphagia predominantly for solid foods during initial stages
- Reflux esophagitis - dysphagia results from inflammatory swelling or a fibrotic stricture
- Pseudoachalasia - underlying malignancy mimics achalasia
- Connective tissue disorders - e.g. systemic sclerosis
- Esophageal spasm - chest pain a predominant feature
Evaluation
- Upper GI
- Esophageal dilatation
- Birds beak sign
- Esophageal Manometry
Management
- Trial of antispasmodic for esophageal spasm
- Surgical intervention
- Balloon dilatation
- Botulinum toxin injection [2]
- Myomectomy
- Consider gastrostomy for frail and older patients
- Patients need to eat upright at all times.
- Treatment may improve dysphagia, but there is no cure and swallowing never completely normalizes
