Gastric Duplication Revealed by Acute Intestinal Obstruction in An Infant: A Case Report

Gastric duplication is a rare congenital anomaly often diagnosed in childhood. Its presentation may vary and can mimic other gastrointestinal conditions.Case Presentation: We report the case of a 1.5-year-old girl admitted for hemorrhagic syndrome and melena. Initial endoscopy suggested chronic gastritis and duodenitis. The patient later developed signs of intestinal obstruction. Imaging showed small bowel thickening without clear etiology. Surgical exploration revealed diffuse peritonitis without clear obstruction. A postoperative CT scan suggested gastric duplication. Reoperation confirmed a communicating gastric duplication, treated by partial gastrectomy. Conclusion: Gastric duplication should be considered in unexplained pediatric gastrointestinal symptoms. Surgical management is curative with favorable outcomes.
