With the development of various diagnostic imaging techniques and minimally invasive treatment tech-niques, the diagnosis and treatment of benign biliary stenosis caused by chronic pancreatitis develop to non-invasive and minimally invasive. The newly developed imaging technology has the characteristics of clear, noninvasive,wide application and high diagnostic rate. In recent years the progress of minimally invasive operation mode compared to the original open operation has less trauma, less blood loss, lower incidence of postoperative complications and faster post-operative recovery and other advantages. The latest da Vinci robotic surgical system has been applied in China and has gradually solved the limitations of laparoscopic surgery,such as the field of vision, the operation is not flexi ble. Ad-vances in diagnosis and treatment of benign biliary stenosis caused by chronic pancreatitis are reviewed for this article for reference.
