An unusual cause of dysphagia: transabdominal Roux-en-Y cyst-jejunostomy in the surgical management of a symptomatic mediastinal cyst.

ABSTRACT

We present a 52-year-old gentleman with an unusual cause of progressive dysphagia, namely due to extrinsic lower oesophageal compression from a cystic mass of the posterior mediastinum. Cystic masses in adults are uncommon, and there is a wide differential diagnosis. This includes neoplastic, such as germ cell tumour (cystic teratoma), and non-neoplastic aetiologies. The later include foregut duplication cysts, lymphatic malformations, infective (hydatid), simple mediastinal cysts or pseudocysts. Management is principally surgical with complete excision, or alternatively, in cases of benign cysts, marsupialization or decompression. In our patient, a simple mediastinal cyst was diagnosed and this case is the first description of a totally transabdominal approach to mediastinal cyst decompression by a Roux-en-Y cyst-jejunostomy.
