Endoscopic retrograde cholangiopancreatography has been a "golden standard" in endoscopic radiological diagnosis and treatment of biliopancreatic pathology for a long time. Possibilities of biliary and pancreatic three imaging, with prompt conversion into therapeutical procedure--papillotomy, stone extraction, biliary and pancreatic stents placement over benign or malignant ductal strictures, is of outstanding value like very few other methods. Since time is measure by itself, "golden age" of ERCP has passed with non-invasive diagnostic procedures. However, in the endoscopic treatment of biliary and pancreatic pathology it still remains to be a golden standard.
