Background: Heterotaxy syndrome is associated with a plethora of cardiovascular and other multi-system anomalies with a high childhood mortality. A dilated azygos vein as part of the polysplenia variant of heterotaxy syndrome may cause oesophageal stenosis owing to a prolonged compression. We describe our technique of extramediastinal oesophago-oesophagostomy in the prone position for this rare congenital syndromic malformation with an excellent outcome. Patients and Methods: A 17-year-old boy with heterotaxy syndrome presented with intermittent dysphagia and postprandial emesis with failure to thrive. Despite the presence of diverse anatomic abnormalities, it was only his symptom of dysphagia due to oesophageal stricture that merited surgical intervention. He underwent an azygos-preserving extramediastinal oesophago-oesophagostomy in the prone position without segmental resection with the establishment of continuity using a modified Collard-type anastomosis. Results: The patient had an uneventful convalescence, with imaging after 1 year showing no re-stenosis. After a follow-up of 3 years, the patient is free of symptoms and has gained weight. Conclusion: Oesophageal stenosis may result from prolonged compression by anomalous vasculature. An isolated correctable anatomic derangement, young age with good functional reserve, other associated anomalies not causing any symptoms, the physiological advantages of executing the surgery in a prone position and availability of expertise in minimally invasive surgery ensured excellent outcomes. The hitherto unreported technique may open up avenues for further research regarding the behaviour of the oesophageal muscular tube with transection and re-anastomosis for rare benign abnormalities.
