Five patients with choledocholithiasis refractory to standard extraction methods after endoscopic sphincterotomy underwent peroral cholangioscopy with the “mother‐daughter” endoscopy system. Electrohydraulic lithotripsy of nine stones was performed successfully and without complication, other than minor transient bleeding in one patient. The outer sheath of the “daughter scope” sustained a linear burn in one instance. This method of stone fragmentation is a useful adjunct to achieve ductal clearance in difficult cases.
