Recently, the number of patients with neurovascular and/or cardiovascular diseases taking antithrombogenic drugs has increased because of aging of the population. The Clinical Endoscopic Guidelines for patients taking antithrombogenic therapy published by the Japan Gastroenterological Endoscopy Society (JGES) was revised in 2012. The new guideline was subdivided according to the types of antithrombogenic drugs. In the setting of emergent pancreatobiliary endoscopic treatment, biliary drainage is basically the most prioritized. In patients who are taking anticoagrant drugs or chenopyridine derivative, however, it may be impossible to choose a precut sphincterotomy even for cases with difficult cannulation, which must be one of the significant remaining issues.
