Abstract

A gastric duplication cyst is a rare congenital anomaly. Among gastrointestinal duplication cysts, gastric duplication cyst account for only 3.8%. They tend to be symptomatic in early childhood, but asymptomatic during adulthood. So its diagnosis is incidental. Abdominal pain is the most common complaint in adults, and most cases are discovered incidentally by radiological examination or endoscopic gastroduodenoscopy. Preoperative diagnosis of gastric duplication cyst is difficult, and definitive diagnosis requires pathological examination of the lesion. So far, about 8 cases of gastric duplication cyst have been reported in adults in the Korean literature. We report here a case of multiple gastric duplication cysts presenting with melena in a 14-year-old man, which were detected by endoscopic gastroduodenoscopy, abdominal computed tomography and endoscopic ultrasonography. They were treated by complete excision of the multiple gastric duplication cysts by laparoscopic wedge resection.
