Core Tip

Core tip: Several studies have compared the efficacy of temporary insertion of an endoscopic nasobiliary drainage (ENBD) tube to a biliary stent until clearance of stones from the common bile duct (CBD) is confirmed. However, few studies have evaluated the benefits in clinical outcomes of ENBD tube placement after clearance of CBD stones. In this study, we found that ENBD is only beneficial when an endoscopic papillary balloon dilatation procedure has been performed.
