Core tip: Endoscopic papillary dilation with a dilating balloon is technically simple and effective. However, there is still debate regarding safety, and there is no guideline or consensus of detailed techniques. Because the procedure is performed to treat a common benign condition, it is important to ensure that there are no lethal procedure-related complications. It, however, can lead to potential morbidity and even death. As the foremost priority is patient safety, it should be performed with appropriate techniques in selected patients. Therefore, we suggest the optimal indications and tips for avoiding severe complications of endoscopic papillary balloon dilation with a small balloon or a large balloon.
