Abstract

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.

Figure

• 

  Fig. 1 A barium esophagography shows a well defined intramural lesion with an intact mucosa in the lower third of the esophagus (arrow).

• 

  Fig. 2 Chest CT scan shows a homogenous, low density mass anterior to the intra-abdominal esophagus.

• 

  Fig. 3 The defect of the muscular layer is shown in the intra-abdominal esophagus (arrow). During the procedure, there was no injury to the mucosal-submucosal layer.

• 

  Fig. 4 Microscopic finding of the cyst wall shows a two-layered muscle coat, and the lining epithelium is pseudo-ciliated columnar cells (HE, ×40).

• 

  Fig. 5 The follow-up barium esophagography shows no leakage or stenosis in the distal esophagus.
