Introduction:
Respiratory distress and arrest from tracheal compression secondary to megaoesophagus are rare complications of achalasia. We present the case of a man with end-stage achalasia who required oesophagectomy to prevent recurrent life-threatening tracheal compression and respiratory arrest. A literature review is also presented.
Presentation of case:
A 40-year old man presented with post-prandial stridor which resolved spontaneously, later being diagnosed with achalasia. He underwent pneumatic dilatation year later, intended as definitive treatment. Despite intervention, the patient had developed megaoesophagus. One month later he presented with tracheal compression and cardiorespiratory arrest but was successfully resuscitated. He subsequently underwent elective oesophagectomy.
Discussion:
Over 40 case reports of achalasia presenting with stridor have been published. However, only three cases (all female, age range, 35-79 years old) of cardiac, respiratory or cardiorespiratory arrest have been published. The definitive treatments received by these patients were botulinum toxin injections, open Heller cardiomyotomy with Dor fundoplication and pneumatic dilatation. None of these patients suffered recurrent respiratory distress following definitive treatment. The patient currently reported was unique as he suffered cardiorespiratory arrest following an intended definitive treatment, pneumatic dilatation. As such oesophagectomy was considered the greatest risk-reduction intervention.
Conclusion:
Oesophagectomy should be considered for patients with end-stage achalasia and mega-oesophagus causing respiratory compromise to avoid potential fatal complications such as tracheal compression and subsequent respiratory arrest.
