Acute onset of esophageal duplication cyst in adult. Case report.

INTRODUCTION: Esophageal duplication (ED) cyst is unusual congenital disorder of the foregut, accounting for 10% to 15% of duplications of all foregut cysts. We report a case of esophageal duplication with acute clinical presentation, treated successfully with surgical resection. CASE REPORT: 46-year-old man with acute dysphagia and gastroesophageal reflux of 2 weeks duration, showed submucosal bulging mass in the posterior wall of the middle third of oesophagus, fluid-filled cystic structure, dyshomogeneous, low-attenuation mass with smooth borders compatible with an hemorrhagic esophageal duplication cyst. With the suspect of acute presentation of a complicated esophageal cyst, the patient underwent surgery by right posterolateral thoracotomy. A gastrografin esophagogram was performed on third postoperative day and showed no leaks. DISCUSSION: Up to 80% of the esophageal duplication cysts are diagnosed in childhood and the majority of young patients develop symptoms, while symptomatic cyst into adult life is very rare (<7%). Acute onset is generally due to complications, i.e. intracystic hemorrhage, perforation, and infection, especially of the cyst with esophageal communication. Complete surgical excision by thoracotomy or thoracoscopy is the therapy of choice even if the patient is asymptomatic because of the risk of complications such as aspiration and bleeding. CONCLUSIONS: The diagnosis and treatment of esophageal cysts is still evolving. The pathological diagnosis of oesophageal duplication requires the presence of the Ladd and Gross criteria. The infrequent acute onset doesn't modify the management and the surgical resection is the procedure of choice. The future of the treatment of esophageal cysts lies in the advancement of minimally invasive operative techniques.
