Core Tip

Core Tip: Current guidelines recommend endoscopic stone removal for asymptomatic common bile duct stones (CBDS). However, the risks of endoscopic retrograde cholangiopancreatography (ERCP)-related complication and natural history outcome of asymptomatic CBDS should be compared to decide on endoscopic treatment by ERCP. ERCP for asymptomatic CBDS reportedly has a high risk of ERCP-related complications; post-ERCP pancreatitis risk being the most common. The long-term natural history of asymptomatic CBDS is not well known. Further studies examining long-term complication risks of ERCP and wait-and-see groups for asymptomatic CBDS are warranted to evaluate whether routine endoscopic stone removal for asymptomatic CBDS is justified or not.
