Endoscopic Papillary Balloon Dilation Versus Small Endoscopic Sphincterotomy for Endoscopic Retrograde Cholangiopancreatography–Related Adverse Events in Patients With Non–Dilated Distal Bile Duct

Non-DDBD patients have a higher risk for endoscopic retrograde cholangiopancreatography-related pancreatic inflammation. EPBD should be used cautiously due to the significant association with increased rates of PEP and HP. Conversely, small EST and combination therapy are suitable for non-dilated bile duct stones because of their high safety profile and efficacy.
