Purpose Endoscopic bile duct clearance is now the treatment of first choice for bile duct stones, particularly in elderly or high‐risk patients. The purpose of this study was to objectively assess the safety, efficiency, and ease of use of percutaneous transhepatic choledochoscopy, using a small‐caliber choledochoscope with a facilitated insertion technique, in high‐risk elderly patients with choledocholithiasis. Methods Sixty‐five consecutive patients with common bile duct stones scheduled for percutaneous transhepatic choledochoscopic lithotomy were studied prospectively. Choledochoscopy was carried out with a simplified introducer system, using a 2.8‐mm choledochoscope with electrohydraulic lithotripsy. Results The common bile duct was successfully accessed and the stones removed in all 65 patients. The average time for the entire procedure was 45min. There were no serious procedure‐related complications. Conclusions Percutaneous transhepatic choledochoscopic lithotomy, using electrohydraulic lithotripsy, is an attractive alternative for patients with common bile duct stones when surgery or retrograde methods are not suitable.
