Core Tip

Core Tip: Ectopic papilla of Vater is scarcely reported. Potential locations of ectopic papilla are the stomach, pyloric canal, duodenal bulb, or third or fourth portion of the duodenum. Anomalous termination in the stomach is rare. Although this anatomy may mislead endoscopic retrograde cholangiopancreatography operators, this nonetheless constitutes a safe and common therapeutic procedure. When no ampulla of Vater is detected in the second portion of the duodenum, ectopic papilla of Vater should be considered.
