Abstract Double pyloric opening (DPO) is a condition in which there are two openings of the stomach in to the duodenum with the normal anatomy in the rest of the stomach. DPO may be considered as a gastroduodenal fistula consisting of a short accessory channel between the distal stomach and the duodenal bulb, such that the gastric antrum and the duodenal bulb are connected by two openings separated by a septum or bridge of tissue1 . This is reported to be a rare anomaly of the stomach which could be congenital or acquired [2-6]. Even though it is considered as a congenital anomaly anatomy textbooks does not state this anomaly in their text under the developmental deformities of the stomach or the duodenum and it is said to be very rare congenital anomaly of which was first reported in 1971 [1]. Mechanism of occurrence of DPO as an acquired condition is said to be secondary to chronic gastric or duodenal ulcers leading to gastro-duodenal fistula [2,4,7]. DPO is most of the time an incidental finding during routine investigation of the upper gastrointestinal tract due to the fact that this is asymptomatic unless present with symptoms related to the concurrent peptic ulcer disease [6,9]. However, some of them have presented with complications such as upper gastro intestinal bleeding and pyloric stenosis. On the other hand inadvertent injury of the abnormal band separating the pyloric cannal is possible during upper gastro intestinal endoscopies. Therefore the knowledge of presence of this anomaly is important for gastrointestinal surgeons and physicians.
