Laparoscopic resection of intra-abdominal esophageal duplication cyst near spleen: a case report

Abstract

Esophageal duplication cysts (EDCs) are congenital malformations of the posterior primitive foregut and often within the thoracic esophagus. Here we describe a rare case of intra-abdominal EDC near spleen in a 20-year-old female patient with a complaint of an asymptomatic abdominal mass for 5 years. The diagnosis of intra-abdominal EDC was confirmed by the Ultrasonography (US) and Magnetic resonance imaging (MRI) as well as Histological examination. Then the patient was received the laparoscopic resection and recovered well after the operation. We conclude that the laparoscopic resection is considered to be feasible and a reasonable treatment for intra-abdominal esophageal duplication cyst.

Figure 1

Ultrasonography shows a hypoechoic cyst with tiny points of light echoes from various axes (A, B). MRI reveals that T1-Weight imaging present low signal (C), T2-Weight imaging present high signal (D, E), contrast-enhanced T1-Weight imaging does not suggest enhancing cystic lesion (F).

This cyst arose from esophagus since its wall was lined by epithelium and was composed of two smooth muscle layers (hematoxylin and eosin stain [H&E], A with original magnification ×40, B with original magnification ×100).
