Complete gastric duplication in an adult with associated anomalies.

Gastric duplication is a rare congenital developmental abnormality usually encountered in children. Nearly all reported cases of this entity describe noncommunicating-type duplication cysts. We present an extremely rare case of complete gastric duplication, involving two separate gastric lumens with proximal and distal communication, incidentally discovered in an elderly male in association with various congenital anomalies not previously reported in literature, as diagnosed with computed tomographic scan and upper gastrointestinal endoscopy.
