[Extracorporeal shockwave lithotripsy of gallstones: how many patients are suitable for it?].
The proportion of patients with gallbladder stones suitable for extracorporeal shockwave lithotripsy (ESWL) was analysed prospectively in 200 patients aged 17-76 years (62 males, 138 females) with symptomatic cholecystolithiasis. Criteria for inclusion were clinical symptoms, solitary stones (diameter 10-30 mm) or up to three stones with comparable total volume, contractile gallbladder, no calcification of stones, normal biliary tract anatomy. To check these criteria a step-by-step diagnostic procedure was instituted which consisted of history, ultrasonography with contractility test, abdominal X-ray film, computed tomography measurement of stone density, and endoscopic retrograde cholangiography. Only 19 patients fulfilled the criteria. The others had to be excluded because of history (35), stone size or number (73), impaired gallbladder contractility (27), calcified stone (30), pigment content (12), and/or biliary tract anatomy. Thus only a surprisingly small percentage (about 10%) of patients with symptomatic gallbladder stones is suitable for ESWL.
