Abstract:Objective:To summaize the experience of application of direct digital radiography and electrohydraulic shockwave lithotripsy in treatment of residual bile duct stones.
Methods :A retrospective analysis of clinical records of 60 patients with residual bile duct stones treated in our hospital from 2003 to 2006 was made.
Results:In 59(95.9%) of 60 cases the stones were removed completely,including successful removal in one time of application of this method in 57 Patients（95.0%）, and 2 applications in 2 Patients ﹙3.3%). One case with bile duct stone complicated with dile duct cancer was unsuccessful. The biggest stone was 3.5cm×2.5cm×2.0cm.No serious complications occurred and changed to operation. The 59 cases were followed up for 6 mo to l yr, and all had a successful outcome.
Conclusions: The method of combination of direct digital radiography and electrohydraulic shockwave lithotripsy in treatment of postoperative residual bile duct stones after operation can facilitate removal of residual bile duct stones.The procedure is a safe way of treating residual stones.
