Congenital gastric duplication: report of three cases with review of the English literature

ABSTRACT

Gastric duplications are quite rare. They may occur in any part of the stomach, commonly arise from the greater curvature. 110 cases have reported in the English literature. On the other hand 7 of these duplications have been reported in the pyloric region. In this paper we report 3 cases of gastric duplication. In 2 cases the duplication arose from the greater curvature and in one case it arose from the pyloric region causing gastric outlet obstruction. Gastric duplication usually presents with a palpable mass and/ or vomiting. Vomiting from duplication in the pyloric region may simulate congenital hypertrophic pyloric stenosis. Surgical treatment is either by total excision with partial gastrectomy or by excision of the dome of the duplication cyst and stripping of the remaining mucosa from the remaining common wall
