Abstract
Since the first report of endoscopic retrograde cholangio-pancreatography (ERCP) in 1986 for the diagnosis of biliary-pancreatic disease, ERCP has become an important means for the diagnosis and treatment of biliary-pancreatic disease. At present, although the success rate of endoscopic selective biliary cannulation is more than 90%, there are still 5%-10% of cases with failed cannulation, for which assistive technology is needed as a supplementary to achieve successful cannulation. Repeated attempts correlate with a higher success rate of cannulation, but also extend the operating time and increase the incidence of complications. In recent years, the concept of difficult biliary cannulation has been put forward and gradually accepted by endoscopic physicians. In the cases of difficult biliary cannulation, endoscopic physicians can adjust the cannulation strategy in time to improve the success rate and reduce the complication rate. This paper summarizes the literature published recently to make a systematic review of the advances in the management of difficult biliary cannulation.
