Congenital anomalies of the biliary tree are rare and present challenges for endoscopists performing interventions such as endoscopic retrograde cholangiopancreatography (ERCP). The reported incidence of ectopic biliary drainage ranges from 2% to 20%, and the condition is often associated with pancreatobiliary complications, including choledocholithiasis (56%), cholangitis (39%), and acute pancreatitis (18.2%). These developmental abnormalities originate during embryogenesis. Uncommon sites for the ampullary opening include the third or fourth part of the duodenum, the stomach, and the pancreatic duct. We report a rare case of ectopic ampulla opening into the pylorus, which presented with cholangitis and was successfully managed with a modified ERCP technique.
