An esophageal duplication cyst that presented with sudden-onset dysphagia / 대한내과학회지

Esophageal duplication is a rare congenital disorder. Although infrequent, complications such as infection, bleeding, and perforation have been reported. Surgical resection is the standard treatment for esophageal duplication cysts. We report the case of a 45-year-old female with an esophageal duplication cyst that presented with dysphagia, with a review of the literature.

Intra-abdominal Esophageal Duplication Cyst in an Adult

Esophageal duplication cysts are congenital anomalies of the foregut that are rarely found in the abdomen. An accurate preoperative diagnosis is not always possible, so the definitive diagnosis can be made by histologic examination of the surgical specimen. We experienced a case of Intra-abdominal esophageal duplication cyst in a 52-year-old female, who initially presented with an esophageal submucosal tumor on upper gastrointestinal endoscopy. She did not have any gastrointestinal symptoms. Barium esophagography, chest computed tomography scan and endoscopic ultrasonography demonstrated the cystic lesion in the intra-abdominal esophagus. Transhiatal enucleation of the lesion was performed successfully via the abdominal approach with no postoperative complications. Histologic study showed that the cyst wall contained a two-layered muscle coat and the surface of the lumen was lined by pseudo-ciliated columnar epithelium. The patient has been doing well without any complaints for 3 months of follow-up period.
