Core Tip
Core tip: Balloon-occluded cholangiography is generally performed to confirm bile duct clearance after performing endoscopic retrograde cholangiography (ERC) for stone retrieval. However, balloon-occluded cholangiography may be an imperfect tool for this diagnostic purpose. In this case series, we demonstrated that 22.7% of patients still had residual stones detected on peroral cholangioscopy after a negative balloon-occluded cholangiography was obtained. All of the residual stones were retracted on the cholangioscopy. Our results reveal that peroral cholangioscopy appears to be a useful tool for both detecting and treating residual common bile duct stones after conventional ERC.
