Core Tip

Core tip: Extracorporeal shock wave lithotripsy (ESWL) and endoscopic retrograde cholangiopancreatography (ERCP) are frequently used for patients with large common bile duct (CBD) stones. The effect of a session of ESWL prior to ERCP for problematic and large CBD stones has not previously been reported. The results of our research suggested that a session of ESWL can aid clearance of CBD in the following ERCP. Also mechanical lithotripsy usage was reduced and extremely large stone (≥ 30 mm) clearance rate can be raised.
