Abstract    With the development and evolution of duodenum endoscopy devices and instruments, endoscopic retrograde cholangiopancreatography (ERCP) has been playing more and more important roles in the treatment of disorders at pancreaticobiliary junction, which includes: benign bile stones, Oddi’s sphincter stenosis, anomalous pancreaticobiliary junction and malignant lesions. The topics are discussed in detail with hand-on experience of the author in the article. The impacted bile stones at the pancreaticobiliary junction can be evacuated by endoscopic sphincterotomy (EST). Surgically incurable malignant lesions can be intraluminally drained by endoscopic retrograde biliary drainage (ERBD) or expandable metallic biliary endoprothesis (EMBE). Severe jaundice can be relieved by endoscopic nasobiliary drainage (ENBD). Oddi’s sphincter stenosis is effectively managed by EST. In addition, the treatment of anomalous pancreaticobiliary junction without dilated common bile duct is still under investigation.
