Extracorporeal piezoelectric shockwave lithotripsy of multiple pancreatic duct stones under ultrasonographic control

The first ultrasonographically controlled fragmentation of multiple pancreatic duct stones of up to 14 mm size by means of extracorporeal, piezoelectric shockwave lithotripsy is reported. On account of the ultrasound localization and continuous control during therapy a nasopancreatic tube for instillation of contrast medium and frequent x-ray checks were not necessary. The 48-year-old patient did not experience any pain during the four treatment sessions and during the follow-up period. No complications were noted.
