Combined treatment of large and calcified gallstones by ESWL and laparoscopic cholecystectomy.
In order to facilitate laparoscopic cholecystectomy in the presence of large gallbladder stones seven patients underwent ESWL before operation.  In six cases (83%) a fragmentation to less than or equal to 1 cm could be achieved by application of 1,605 to 2,900 (mean 2,266) shock waves with the spark-gap lithotripter Philips-Dornier MFL 5000.  In these cases intraoperative stone destruction or an increase of the puncture incision size could be avoided, thus proving the efficacy of this combined treatment approach.  Laparoscopic inspection was performed 2 to 48 hours after ESWL.  Including two additional cases operated because of unsuccessful ESWL, hematomas of the liver and adjacent organs were observed in six of nine patients (67%).  This high rate of subclinical tissue lesions warrants caution if repeated ESWL sessions are scheduled at short-term intervals.
