- Abstract
Summary Background : There is some uncertainty as to whether high-risk patients with difficult common bile duct stones should be subjected to a further endoscopic procedure for the complete removal of stones by electrohydraulic lithotripsy or whether permanent biliary stenting should be performed. Aim : To compare the outcome of permanent biliary stenting with electrohydraulic lithotripsy in this group of patients. Methods : In a prospective study, 36 patients with difficult common bile duct stones were investigated: 19 underwent double pigtail insertion (stent group), whereas 17 underwent complete clearance of stones (electrohydraulic lithotripsy). Results : In the electrohydraulic lithotripsy group, successful stone clearance was achieved in 76.5%, whereas, in the stent group, the success of stenting was 94.7%. A significant difference was detected in the actuarial incidence of recurrent acute cholangitis when the electrohydraulic lithotripsy group was compared with the stent group [one patient (7.7%) vs. 12 patients (63.2%), respectively; P = 0.002, log rank test]. A significant difference was detected in the actuarial frequency of mortality between the electrohydraulic lithotripsy and stent groups [seven patients (41.2%) vs. 14 patients (73.7%), respectively; P = 0.01, log rank test]. Conclusions : The removal of difficult common bile duct stones by electrohydraulic lithotripsy and further endoscopic retrograde cholangiopancreatography has a high success rate and a low complication rate even in the elderly.
