ABSTRACT
BACKGROUND:
Extracorporeal shock wave lithotripsy (ESWL) for difficult common bile duct (CBD) stones is a safe and effective treatment strategy allowing for bile duct clearance in approximately 90% of patients with a low incidence of mild adverse events.OBJECTIVE:
To compare the CBD clearance rates achieved after ESWL performed with 2 different lithotripters (Siemens Lithostar Plus and Storz Modulith SLX-F2) in a large cohort of patients with difficult CBD stones.DESIGN:
A retrospective analysis of a prospectively collected database.SETTING:
Tertiary care center. PATIENTS All of the consecutive patients who underwent ESWL because of difficult CBD stones between 1990 and 2012 were considered suitable for inclusion.INTERVENTIONS:
ESWL with Lithostar Plus or with Modulith SLX-F2. MAIN OUTCOME MEASUREMENTS CBD clearance.RESULTS:
Three hundred ninety-two patients with difficult CBD stones were treated; 199 patients were treated with the Lithostar Plus and 193 patients with the Modulith SLX-F2. CBD clearance was achieved in 349 patients (89.0%) with no significant difference between the patients treated with Lithostar Plus and those treated with Modulith SLX-F2 (90.5% vs 87.6%; P = .45). Patients treated with Modulith SLX-F2 underwent a significantly lower number of ESWL sessions (3 [range, 2 to 4] vs 3 [range, 2 to 4]; P = .0015), had a lower incidence of ESWL-related adverse events (5.2% vs 13.6%; P = .009), and never required opioid analgesia (P < .001).LIMITATIONS:
Retrospective design.CONCLUSIONS:
The Modulith SLX-F2 allows the same clearance rate as the Lithostar Plus but has a significantly lower incidence of adverse events and requires fewer ESWL sessions.
