Esophageal achalasia and coexistent upper esophageal sphincter relaxation disorder presenting with airway obstruction.
Acute airway obstruction associated with esophageal achalasia is an uncommon but life-threatening complication. The pathophysiology of this phenomenon has not been fully defined. A fully documented case of coexistent esophageal achalasia and upper esophageal sphincter relaxation abnormality presenting with airway obstruction is reported. The patient was initially treated with Heller's myotomy but had a recurrence of respiratory distress. She was successfully treated by cricopharyngeal myotomy. The causes of gas entrapment and respiratory distress are likely to be due to failure of both swallow- and distention-induced upper esophageal sphincter relaxation. Cricopharyngeal myotomy is an effective treatment for this complication, probably by facilitating esophagopharyngeal gas venting.
