Congenital gastric ectopic pylorus: a rare gastric malformation

A 71-year-old man who presented with hematemesis and melena was admitted to our hospital. He denied any previous surgery history or recent use of alcohol and antithrombotic agents. Esophagogastroduodenoscopy (EGD) revealed an opening leading to the duodenum and the blind antrum without normal pylorus (Fig. 1,Fig. 2). The ectopic pyloric opening was located in the lesser curvature of the upper gastric body, approximately 2 cm distal to the cardia. Multiple ulcers were also found near the opening without active bleeding (Video 1). The upper gastroenterography and computed tomography showed the teapot-like stomach, further confirming the ectopic pyloric opening in the upper gastric body (Fig. 3,Fig. 4). With conservative medication, the patient gained a rapid recovery and was discharged uneventfully.
