Abstract
Because fatty acid composition of biliary phospholipids influences cholesterol secretion into bile, we investigated whether replacement of n-1 monounsaturated or n-6 polyunsaturated fatty acids with n-3 polyunsaturated fatty acids in biliary phosphatidylcholines reduces supersaturation with cholesterol and prevents precipitation of cholesterol crystals in bile of gallstone patients. Seven patients with radiolucent gallstones in functioning gallbladders were studied before (control) and after 5 wk of dietary supplementation with marine fish oil (11.3 gm/day = 3.75 gm n-3 polyunsaturated fatty acids/day). Duodenal bile was collected for analysis during intravenous infusion of cholecystokinin. Gallbladder emptying in response to cholecystokinin was comparable before and during intake of n-3 polyunsaturated fatty acids. Intake of n-3 polyunsaturated fatty acids increased (p less than 0.001) the fractions of eicosapentaenoic and docosahexaenoic acids and decreased the fractions of linoleic (p less than 0.001) and arachidonic acids (p less than 0.02) in biliary phospholipids. Concomitantly, the molar ratio of cholesterol to phospholipids decreased (-19%; p less than 0.05). As a consequence, the cholesterol saturation index was reduced by -25% (p = 0.01), from 1.60 +/- 0.44 to 1.24 +/- 0.38. However, in vitro nucleation time of duodenal bile was not prolonged. The decrease in cholesterol saturation was not sufficient to prevent nucleation of cholesterol crystals in bile of gallstone patients. In conclusion, our data suggest that cholesterol saturation can be influenced by the fatty acid composition of the phosphatidylcholines secreted in bile.

Abstract
Extracorporeal shock wave lithotripsy of pancreatic duct stones (largest stone 12 (SD) 6 mm) was performed in 24 patients with abdominal pain and a dilated duct system (main pancreatic duct 10 (3) mm). The procedure was well tolerated in all but two patients, who had a mild pancreatitic attack immediately after lithotripsy. Disintegration of the stones was achieved in 21 patients. This allowed complete clearance of the duct system by an endoscopic approach in 10 (42%) patients and partial clearance in 7 (29%) patients. Within a mean follow up period of 24 (14) months half of the patients showed complete or considerable relief of pain and alleviation of symptoms was achieved in seven patients. Relief of pain occurred more often after complete ductal clearance. There were no fatalities within the follow up period. These findings underline the value of a combined non-surgical approach, using endoscopy and adjuvant shock wave lithotripsy to patients with large pancreatic calculi and pain attacks.

Abstract
In 97 patients with radiolucent solitary gallbladder stones, the density of the calculi was evaluated by computed tomography (CT) prior to extracorporeal shock wave lithotripsy (ESWL). Sixty-three percent of the stones were isodense to bile (mean 48 +/- SD 11 HU), and 37% could be identified on CT-sections (maximal density 105 +/- 46 HU, mean density at the largest cross-section 53 +/- 31 HU). There was a slight trend toward better stone fragmentation and higher clearance rate in patients with isodense stones. However, the probability of complete fragment clearance was not significantly different in stones with a high or low CT-density. From these data we conclude that stone selection for ESWL and adjuvant bile acid therapy in patients with radiolucent solitary stones as assessed by oral cholecystography is only marginally improved by computed tomography.

Abstract
Safety and efficacy of shock-wave lithotripsy and bile acid dissolution therapy of patients with gallbladder calculi with a radiopaque rim were evaluated. Eighty-six patients with symptomatic solitary stones were treated by this noninvasive therapy and were followed up to 18 months. Three different lithotripsy treatment modalities were used. Up to 1600 shock wave discharges were applied. Patients in group A (n = 20) were treated with an electrohydraulic water-bath lithotripter at a discharge voltage of 18 +/- 1 kV (mean +/- SD), group B patients (n = 25) were treated with an electrohydraulic water-cushion lithotripter at 19 +/- 2 kV, and group C patients were treated (n = 41) with the same lithotripter at 22 +/- 2 kV. Five to eight months after lithotripsy, 15% in group A were free of fragments compared with only 4% in group B (NS vs. group A), and 38% in group C had no stones (NS vs. group A; P = 0.007 vs. B). Thirteen to eighteen months after lithotripsy, the respective results were 59% in group A, 37% in group B (NS vs. group A), and 68% in group C (NS vs. group A; P = 0.05 vs. group B). Patients with fragments of less than or equal to 3 mm in diameter showed significantly better fragment clearance than those with larger fragments. The frequency of adverse effects was not significantly different between the three groups. Biliary colic occurred in 43% of the patients and mild biliary pancreatitis in 3 patients. Endoscopic sphincterotomy was required in 1 patient, and elective cholecystectomy was performed in 6 patients. Using a water-cushion lithotripter at high-power setting, selected patients with solitary gallbladder stones with a radiopaque rim may be treated safely and successfully by shock-wave lithotripsy combined with bile acid dissolution therapy.

Abstract
Over 5 yr, 103 elderly patients (mean age = 70 yr) with bile duct stones (mainly not amenable to endoscopic extraction) underwent adjuvant extracorporeal shock-wave lithotripsy using a first-generation kidney lithotripter. Disintegration of stones was achieved after a mean of 1.4 sessions in 92% of the patients. Spontaneous passage of fragments into the duodenum occurred in one fourth of the patients, and endoscopic extraction of fragments was necessary in 75% of the patients, resulting in complete clearance of the bile duct stones in 91 (88%) of 103 patients. The most important adverse effect was septic disease after extracorporeal shock-wave lithotripsy in 4% of the patients. The 30-day mortality rate was 1% (one patient), and another 15 patients died during a mean follow-up of 26 +/- 14 mo (mainly of causes unrelated to biliary tract disease). Two of 91 patients who had been rendered stone free were readmitted because of recurrent stone disease during the follow-up period. Of the 43 patients who still had their gallbladders during extracorporeal shock-wave lithotripsy, 14% subsequently underwent cholecystectomy. These data show that extracorporeal shock-wave lithotripsy of bile duct stones is a useful and safe adjunct to nonsurgical procedures for the removal of calculi in the biliary tree.

Abstract
A prospective, double-blind, randomized, single-center study was conducted to compare ursodeoxycholic acid alone with the combination of ursodeoxycholic acid and chenodeoxycholic acid for dissolution therapy of gallstone fragments after shock wave lithotripsy. Patients with single radiolucent gallstones up to 30 mm in diameter or up to three stones of similar total volume received either 750 mg ursodeoxycholic acid alone (group A, n = 138) or the combination of 500 mg ursodeoxycholic acid and 500 mg chenodeoxycholic acid (group B, n = 144) in a single bedtime dose. The bile acids were administered from 2 wk before electrohydraulic lithotripsy until 3 mo beyond complete disappearance of all fragments. Patient's characteristics, stones (group A, 82% single stones, maximum diameter 19 +/- 5 mm, mean +/- S.D.; group B, 82% single stones, 18 +/- 5 mm), lithotripsy treatment and follow-up period were not different between the two groups. Between the two groups, no statistically significant difference was found in the time required for complete clearance of the fragments (group A, median time = 15 mo; group B, median time = 13 mo; p = 0.7). At 12 mo after lithotripsy, the probability of complete clearance was 46% +/- 5% in group A and 49% +/- 5% in group B. Diarrhea occurred significantly more often in group B than in group A (p less than 0.001) and was the main reason for withdrawal of randomized medication. Severe adverse effects of the bile acids were not observed. It is concluded that monotherapy with ursodeoxycholic acid is as efficient as the combination of ursodeoxycholic acid and chenodeoxycholic acid for fragment dissolution after lithotripsy.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Twenty-four patients with symptomatic gallbladder stones (12 radiolucent and 12 calcified) were treated by a combined approach of extracorporeal shock-wave lithotripsy (ESWL) and subsequent instillation of methyl tert-butyl ether (MTBE). The patients received a mean of 1500 +/- 185 shock-wave discharges. The mean instillation time of MTBE was 13 +/- 4.2 hr. Treatment was tolerated without major adverse effects. Within a time period of three to five days eight of 12 patients with pure radiolucent stones and four of 12 with calcified stones became stone-free. After a median follow-up of five months (range: one week to 26 months), a total of 11 patients (92%) with radiolucent stones and of eight patients (66%) of those with calcified stones were free of stones, fragments, or debris. These clearance rates appear high when compared with reports on monotherapy with ESWL or MTBE, suggesting a positive effect of a combined approach in selected patients. Two patients exhibited recurrent stones after six and seven months, respectively.

Abstract
OBJECTIVE To evaluate the long-term results of three types of shock wave treatment in patients with radiolucent gallbladder stones. DESIGN Cohort study. SETTING Single-center trial. PATIENTS Of 5824 patients with gallstones, 19% were eligible; 711 patients were treated. INTERVENTIONS Patients received extracorporeal shock wave lithotripsy as well as adjuvant therapy with bile acids. RESULTS Lithotripsy was done in three ways, using a water-tank lithotriptor (group A), a water-cushion lithotriptor at low energy levels (group B), and a water-cushion lithotriptor at high energy levels (group C). The rate of complete fragment clearance 9 to 12 months after lithotripsy was done differed significantly among the three groups: Among patients with single stones of 20 mm or less in diameter, the rate of fragment clearance for group A was 76%; for group B, it was 60%; and for group C, it was 83% (P = 0.03). Among patients with single stones of 21 to 30 mm, the rate of fragment clearance for group A was 63%; for group B, it was 32%; and for group C, it was 58% (P less than 0.005). Among patients with two or three stones, the rate of fragment clearance for group A was 38%; for group B, it was 16%; and for group C, it was 46% (P = 0.01). Patients with fragments of 3 mm or less 24 hours after lithotripsy was done showed a higher probability of fragment disappearance than did those with larger fragments (P less than 0.001). The clearance rate was higher in patients who were compliant than in those who were noncompliant with bile acid therapy (P less than 0.001). Adverse effects included liver hematoma in 1 patients, biliary pain attacks in 253 patients (36%), mild biliary pancreatitis in 13 patients (2%), and cholestasis in 7 patients (1%). Elective cholecystectomy was done in 16 patients (2%), and endoscopic sphincterotomy was done in 4 patients (1%). CONCLUSIONS The rate of complete disappearance of stones after shock wave therapy depends on the size and the number of the initial stones, the diameter of the largest fragment, and the mode of shock wave treatment. Adjuvant therapy with bile acids appears to be important for complete fragment clearance.

Abstract
Extracorporeal shock-wave lithotripsy combined with adjuvant bile-acid dissolution therapy results in complete clearance of stone fragments in a high percentage of selected patients with radiolucent gallbladder calculi. With the gallbladder in situ, these patients are at risk of stone recurrence. Therefore, the early rate of stone recurrence after successful lithotripsy was evaluated. Fifty-eight of the first 60 consecutive patients who became stone free underwent follow-up examinations at least 1 yr (range, 12-37 mo; mean +/- SD, 18 +/- 6) after discontinuation of adjuvant bile-acid therapy. Five patients reported recurrent biliary pain within 1 yr after lithotripsy, and recurrent gallstones were detected. Fifty-three patients were asymptomatic during the first yr, and no recurrence was detected. Thus, the rate of gallstone recurrence was 9% within 1 yr. The rate of gallstone recurrence up to 3 yr was estimated by actuarial analysis. The probability of stone recurrence was 11% (+/- 4%) at 1.5 yr, and no further increase was observed up to 3 yr. Gallstone recurrence within 1 yr after successful shock-wave therapy has to be expected in approximately the same percentage of patients as has been reported in earlier postdissolution trials. It causes recurrent biliary pain in most cases.

Abstract
Extracorporeal shock wave lithotripsy of pancreatic stones was performed in eight patients with chronic pancreatitis and a dilated duct system harbouring stones 5 to 20 mm (means 10 (SD) 5 mm) in diameter. After endoscopic sphincterotomy of the pancreatic orifice the stones were disintegrated by shock waves under fluoroscopic control using a kidney lithotripter (Dornier HM3). The procedure was well tolerated by all but one patient, who had a mild pancreatitic attack immediately after lithotripsy. Clearance of the pancreatic duct systems from the larger stones was achieved in seven of eight patients. Half of the patients showed no improvement in the intensity and frequency of pain. The other patients had a marked amelioration of symptoms, however, both immediately and during a mean follow up interval of 11 (eight) months. A selective combined approach by endoscopy and extracorporeal shock wave lithotripsy for the treatment of pancreatic stones seems promising.

Abstract
A patient with gastric outlet syndrome (Bouveret's syndrome) caused by a large gallstone impacted in the duodenal bulb was successfully treated by extracorporeal shock-wave lithotripsy. Thus, open abdominal surgery could be avoided. For disintegration of the stone, three consecutive lithotripsy procedures were necessary. Thereafter, stone fragments could be extracted endoscopically. Extracorporeal shock-wave lithotripsy could become a non-surgical alternative in patients with obstruction of the duodenum caused by a gallstone.

Abstract
Five cases of surgical intervention following extracorporeal shock wave lithotripsy (ESWL) of gallbladder and bile duct stones are reported. This represents an incidence of surgical intervention in 1% of patients with gallbladder stones and in 9% of patients with common bile duct stones who underwent ESWL during a two-and-a-half-year investigation period. There was no mortality. In 2 patients with gallbladder stones and persistent colic after ESWL, elective cholecystectomy was performed. There was no evidence of macroscopic or microscopic damage or bleeding within the wall of the gallbladder. Furthermore, no damage to the liver, common bile duct, duodenum, or stomach was noted. ESWL was applied in 34 patients with common bile duct stones in whom endoscopic sphincterotomy and stone extraction had proved ineffective. Three (9%) of these patients required surgery. In 1 patient, a Dormia basket got stuck and the basket, together with the stone, were removed by choledochotomy. In a second patient, rupture of a juxtapapillary diverticulum occurred 10 days after ESWL and 2 days after endoscopic extraction of stone fragments. At laparotomy, the retroperitoneum was drained. In a third patient with gallbladder and common bile duct stones, acute cholecystitis developed after lithotripsy of common bile duct stones. Cholecystectomy was performed and a t-tube was inserted in the bile duct. In all patients, the postoperative course was uneventful. In our experience, ESWL is a safe procedure with no mortality and an infrequent need for surgical intervention.

Abstract
To determine whether extracorporeal shock-wave lithotripsy of gallbladder stones alters gallbladder motility, gallbladder contraction in response to intravenous cholecystokinin was investigated by ultrasound. Twenty-one patients with symptomatic gallstones were studied before and after shock-wave lithotripsy, 12 with and 9 without concomitant litholytic therapy (combination of ursodeoxycholic acid and chenodeoxycholic acid). Gallbladder emptying was significantly delayed and less complete in both groups of patients before shock-wave treatment (with bile salts: residual volume, 51% +/- 10% and half-ejection time, 40 +/- 5 min; without bile salts: residual volume, 46% +/- 7%; half-ejection time, 30 +/- 4 min) compared with healthy controls (residual volume, 15% +/- 4%; half-ejection time, 18 +/- 2 min). Gallbladder motility was not altered in either group 1 day and 1 yr after lithotripsy. The findings indicate (a) that extracorporeal shock-wave lithotripsy has no immediate or long-term adverse effects on gallbladder motility and (b) that the defect of gallbladder motility associated with gallstone disease is not abolished by removal of the stone.

Abstract
Eighty in vitro experiments were performed with single (n = 51) or multiple (n = 29) gallstones in order to find out which parameters are of prime importance for their disintegration by extracorporeal shock waves. A Dornier lithotripter and an upper limit of 1,500 discharges were employed. Although computed tomography density was significantly lower in cholesterol stones than in the noncholesterol stones (p less than 0.0001) and although the latter were significantly more often radiopaque (p less than 0.0001), we found no clear-cut correlation between the cholesterol content or computed tomography density and the degree of fragmentation of the stones. The most important variable which limited successful disintegration was the total stone volume. In stones with a mean total volume of 0.83 ml +/- 0.25 S.E. (diameter for single stones = 11.5 +/- 0.9 mm), none of the fragments exceeded 2 mm, whereas in stones with a mean volume of 3.6 ml +/- 0.64 (diameter = 17.2 +/- 1.5 mm) at least one fragment larger than 2 mm remained (p less than 0.002). Under the in vitro conditions, fragmentation was similar in multiple and solitary stones, provided the volume of the stones was comparable. These data show that, in general, the number and size of the stones, i.e. their total volume, and much less significantly their chemical composition are the major determinants of fragmentation by extracorporeal shock waves.

Abstract
To substantiate the early results of extracorporeal shock-wave fragmentation of gallstones, we used this nonsurgical procedure to treat 175 patients with radiolucent gallbladder calculi. Chenodeoxycholic acid and ursodeoxycholic acid were administered as adjuvant litholytic therapy. The gallstones disintegrated in all patients except one and completely disappeared in 30 percent of all patients within 2 months after lithotripsy, in 48 percent at 2 to 4 months, in 63 percent at 4 to 8 months, in 78 percent at 8 to 12 months, and in 91 percent at 12 to 18 months. In patients with solitary stones up to 20 mm in diameter, the corresponding values were 45, 69, 78, 86, and 95 percent, respectively. Shock-wave therapy had no adverse effects except cutaneous petechiae (14 percent) and transient gross hematuria (3 percent). One third of the patients had one or more episodes of biliary colic before all the fragments disappeared. Two patients had mild pancreatitis, which necessitated endoscopic sphincterotomy in one. The patient with insufficient stone fragmentation underwent elective cholecystectomy; no additional operations were necessary. Extracorporeal shock-wave lithotripsy combined with medical therapy for stone dissolution is a safe and effective treatment in selected patients with radiolucent gallbladder calculi.

Abstract
Extracorporeal shock-wave lithotripsy has been introduced as a novel nonsurgical therapy for gallstone disease. To substantiate the initial results, more than 400 patients with biliary calculi have been treated. In selected patients with gallbladder stones, complete clearance of all stone fragments can be expected within 1 year in about 80%. In patients with bile-duct stones not amenable to endoscopic measures, sufficient stone fragmentation by extracorporeal shock waves was achieved in about 80%. Extracorporeal shock-wave lithotripsy is a safe and efficient therapy for selected patients with gallbladder calculi. For patients with bile-duct stones not amenable to endoscopic measures it offers a nonsurgical alternative.

Abstract
We report the case of a 33-year-old woman with chronic calcifying pancreatitis in whom an intraductal pancreatic stone with a diameter of 8 mm was successfully disintegrated with extracorporeal shock waves, permitting subsequent endoscopic extraction of the fragments. The patient had a mild attack of pancreatitis after the treatment. We conclude that shockwave lithotripsy of a pancreatic duct stone in patients with chronic pancreatitis is possible. It should, however, be viewed with reservation until further experience has been gained.

Abstract
We report four consecutive cases in which postoperative cutaneous biliary fistulas were treated successfully by an endoscopically placed nasobiliary tube or an endoprosthesis. This simple and effective method should be considered in selected patients as a viable alternative to established surgical procedures.
