출혈을 동반한 위중복증(Gastric duplication)

Duplications of alimentary tract are unusual congenital anomalies composed of cystic or tubular structure that is closely attached or communicated with the gastrointestinal tract. Ileum is the most common site of duplications of alimentary tract, whereas the stomach is the least common site. The majority of gastric duplication is diagnosed at infancy and a few case is diagnosed at adult. We experienced a case of cystic gastric duplication in a 45 years-old female who had presented with hematemesis. About 2×2㎝ sized, round and elevated mass was noted at posterior wall of stomach on gastrofiberscopy. It was confirmed as cystic duplication after surgery.(Korean J Gastroenterol 1997;29:836-840)
