[Interdisciplinary treatment of gallstones: surgery, endoscopy, lithotripsy. Report of experiences after 4 years].

Today, several methods of treatment for gall stone disease exist besides standard surgical procedures: endoscopy, lithotripsy, litholysis or a combination of the above. During the last four years 1786 patients were treated using an interdisciplinary approach. Cholecystectomy was still the most frequent method of treatment for symptomatic cholecystolithiasis (n = 1369) with low morbidity (4.3%) and lethality (0.28%). Probably less than 20% of all cases fulfill the strict selection criteria for extracorporeal shock wave lithotripsy (ESWL). All alternative methods of treatment in which the gallbladder is preserved have an increased risk for gall stone recurrence. Only after the long-term follow-up results of ESWL are known, the recurrence rate can be assessed. In most cases, bile duct stones (n = 417) were removed by endoscopy, if necessary in combination with ESWL (n = 310, stone removal: 95%, lethality: 0.3%). However, in low risk patients with concurrent cholecystolithiasis surgery was still the method of choice (n = 107, stone removal: 96%, lethality: 0/107). It seems not so important as to who performs the non-surgical procedures in the treatment of gall stones - the surgeon, internist or radiologist. Moreover, an interdisciplinary approach should be sought.
