Upper pouch oesophageal duplication cyst- A rare association with Tracheoesophageal fistula: A case report

Background: Oesophageal atresia (OA) has associated anomalies in 50 to 70 % of cases. The usual associations include cardiac, gastrointestinal, anorectal, renal, vertebral, or skeletal anomalies. Oesophageal duplication cyst as an association in OA is extremely rare. Despite the related embryogenesis of these two anomalies, there are very few cases reported. Case Presentation: We present a low-birth-weight neonate with Type C Tracheo-oesophageal fistula (TEF) with an associated oesophageal duplication cyst. Conclusion: Upper pouch oesophageal duplication with TEF is very rare and this is the fourth case managed concomitantly at primary surgery in English literature available.

Surgical treatment of a thoracic oesophageal duplication cyst causing recurrent dysphagia in an adult dog

A 7-year-old intact male Rottweiler dog was evaluated for recurrent dysphagia and regurgitation. Physical examination was unremarkable and routine blood works were within normal limits. Computed tomography revealed a defined lesion in the caudal mediastinum arising from the oesophagus. The lesion was excised using intercostal thoracotomy and the histological diagnosis was oesophageal duplication cyst. The dog recovered uneventfully and at a 3-year follow-up no clinical signs were reported. Although extremely rare, oesophageal duplication cysts should be considered in the differential diagnosis in cases of chronic regurgitation and dysphagia associated with evidence of an oesophageal lesion.
