Endoscopic retrograde cholangiopancreatography helps to improve the diagnostic rate of periampullary duodenal diverticula. The importance of periampullary duodenal diverticula in clinical practice lies in its close association with bile duct stones, and different types of periampullary duodenal diverticula have different associations with the development and recurrence of bile duct stones. This article reviews the epidemiology, typing, pathogenesis, and treatment of periampullary duodenal diverticula and the association between different types of periampullary duodenal diverticula and the development and recurrence of bile duct stones, in order to provide a reference for the diagnosis and treatment of periampullary duodenal diverticula complicated by bile duct stones in future
