Abstract
Gallstones are one of the most common diseases worldwide. Recently, the incidence of gallstones has increased and the pattern of gallstones has changed in Korea. Laparoscopic cholecystectomy is the standard treatment for symptomatic gallstones. Expectant management is considered the most appropriate choice in patients with asymptomatic gallstones. The dissolution of cholesterol gallstones by oral bile acid, such as ursodeoxycholic acid, can be considered in selected patients with gallstones. Although the advent of laparoscopic cholecystectomy has moved interest away from the pharmacologic treatment of gallstones, several promising agents related to various mechanisms are under investigation.

Abstract
Cholelithiasis is one of the commonest diseases in gastroenterology. Remarkable improvements in therapeutic modalities for cholelithiasis and its complications are evident. The Japanese Society of Gastroenterology has revised the evidence-based clinical practice guidelines for cholelithiasis. Forty-three clinical questions, for four categories-epidemiology and pathogenesis, diagnosis, treatments, and prognosis and complications-were selected, and a literature search was performed for the clinical questions with use of the MEDLINE, Cochrane, and Igaku Chuo Zasshi databases for the period between 1983 and June 2012. The guidelines were developed with use of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. This article preferentially describes the clinical management of cholelithiasis and its complications. Following description of the diagnosis performed stepwise through imaging modalities, treatments of cholecystolithiasis, choledocholithiasis, and hepatolithiasis are introduced along with a flowchart. Since there have been remarkable improvements in endoscopic treatments and surgical techniques, the guidelines ensure flexibility in choices according to the actual clinical environment. The revised clinical practice guidelines are appropriate for use by clinicians in their daily practice.

Abstract
Different sclerosing agents were tried in experiments with 32 pigs to achieve ablation of gallbladders rendered edematous by mechanical lithotripsy with the Rotolith lithotriptor. In 16 pigs sclerotherapy was performed with 6% acetic acid, Carnoy's solution, 95% ethanol + 3% sodium-tetradecylsulfate (STS) and hot metrizoate, respectively. These animals were sacrificed immediately after the procedure. Histologic examination showed persistent surface epithelium and glandular epithelium in all specimens. In 6 pigs, the sclerotherapy was done with Carnoy's solution, 95% ethanol + 3% STS and hot metrizoate, respectively, and the pigs were killed 6 days later. Fibrosis of the gallbladder remnants was seen in these animals, but also remnants of surface and glandular epithelium. Hot metrizoate was used in another 10 pigs and these animals were sacrificed after 8 weeks. At histologic examination fibrosis was seen in the gallbladder remnants of 9 surviving animals, but also areas of preserved muscular layer, and development of mucinous cysts were found in more than 50% of the specimens. Thus, none of the sclerosants was able to produce a total ablation of the gallbladder mucosa.

Abstract
Cholesterol gallstone disease is a common clinical condition influenced by genetic factors, increasing age, female gender, and metabolic factors. Although laparoscopic cholecystectomy is currently considered the gold standard in treating patients with symptomatic gallstones, new perspectives regarding medical therapy of cholelithiasis are currently under discussion, also taking into account the pathogenesis of gallstones, the natural history of the disease and the analysis of the overall costs of therapy. A careful selection of patients may lead to successful non-surgical therapy in symptomatic subjects with a functioning gallbladder harboring small radiolucent stones. The classical oral litholysis by ursodeoxycholic acid has been recently paralleled by new experimental observations, suggesting that cholesterol-lowering agents which inhibit cholesterol synthesis (statins) or intestinal cholesterol absorption (ezetimibe), or drugs acting on specific nuclear receptors involved in cholesterol and bile acid homeostasis, might be proposed as additional approaches for treating cholesterol gallstones. In this review we discuss old, recent and future perspectives on medical treatment of cholesterol cholelithiasis.

Abstract
Gallstones have led to pain and complications in humankind for millennia. Beginning in the 1880s, cholecystectomy, performed through a sizable abdominal incision, was the treatment of choice for symptomatic cholelithiasis. During the late 1980s pioneering surgeons first used laparoscopic techniques to remove the gallbladder. Although initially associated with a significantly increased rate of bile duct injury, the clinical advantages of laparoscopy compared to open operation became readily apparent, ushering in the "laparoscopic revolution." More recently, attempts at rendering cholecystectomy even less invasive--smaller or fewer incisions or eliminating abdominal incisions altogether--have been described, with limited clinical series reported. At the current time, laparoscopic cholecystectomy is the gold standard for gallbladder removal, and any newer techniques must be demonstrated to result in superior outcomes for widespread adoption.

Abstract
Gallstone disease is a frequent condition throughout the world and, cholesterol stones are the most frequent form in Western countries. The standard treatment of symptomatic gallstone subjects is laparoscopic cholecystectomy. The selection of patients amenable for nonsurgical, medical therapy is of key importance; a careful analysis should consider the natural history of the disease and the overall costs of therapy. Only patients with mild symptoms and small, uncalcified cholesterol gallstones in a functioning gallbladder with a patent cystic duct are considered for oral litholysis by hydrophilic ursodeoxycholic acid, in the hope of achieving cholesterol desaturation of bile and progressive stone dissolution. Recent studies have raised the possibility that cholesterol-lowering agents that inhibit hepatic cholesterol synthesis (statins) or intestinal cholesterol absorption (ezetimibe), or drugs acting on specific nuclear receptors involved in cholesterol and bile acid homeostasis, may offer, alone or in combination, additional medical therapeutic tools for treating cholesterol gallstones. Recent perspectives on medical treatment of cholesterol gallstone disease are discussed in this article.

Abstract
A review is presented of Gustav Paumgartner's five decades of research and practice in hepatology focusing on biliary physiology and disease. It begins with studies of the excretory function of the liver including hepatic uptake of indocyanine green, bilirubin, and bile acids. The implications of these studies for diagnosis and understanding of liver diseases are pointed out. From there, the path of scientific research leads to investigations of hepatobiliary bile acid transport and the major mechanisms of bile formation. The therapeutic effects of the hydrophilic bile acid, ursodeoxycholic acid, have greatly stimulated these studies. Although ursodeoxycholic acid therapy for dissolution of cholesterol gallstones and some other nonsurgical treatments of gallstones were largely superseded by surgical techniques, ursodeoxycholic acid is currently considered the mainstay of therapy of some chronic cholestatic liver diseases, such as primary biliary cirrhosis. The major mechanisms of action of ursodeoxycholic acid therapy in cholestatic liver diseases are discussed. An attempt is made to illustrate how scientific research can lead to advances in medical practice that help patients.

Abstract
OBJECTIVE To investigate the frequency of variants at Xmn I, Msp I sites of apolipoprotein (Apo), A I-CIII-AIV gene cluster, and its relation to cholesterol gallstones in Chinese patients. METHODS Restriction fragment length polymorphisms (RFLP) at Xmn I, Msp I sites of ApoAI-CIII-AIV gene cluster were studied using a polymerase chain reaction (PCR) in 161 patients with cholesterol gallstones and 94 healthy subjects from a Chinese population in Sichuan Province. RESULTS In both the cholesterol gallstone group and the healthy control group, X1 and M1 alleles were the major alleles and homozygous X1X1 and M1M1 genotypes were the most frequent. However, the frequency of X2 allele mutation in female patients of the cholesterol gallstones group was significantly higher than that in women in the healthy control group (P<0.05), but no difference was found in the frequency of M2 alleles mutation (P>0.05). CONCLUSION The data showed that Xmn I RFLP of ApoAI-CIII-AIV gene cluster is associated to some extent with cholesterol gallstones in female Chinese patients.

Abstract
OBJECTIVE Reports concerning long term recurrence of gallstones after successful extracorporeal shock wave lithotripsy (ESWL) show a high probability of stone recurrence. There is still discussion on the factors influencing stone recurrence. In this study we wanted to evaluate the long term recurrence of gallstones after stone clearance with ESWL and oral bile acids, and to assess possible risk and preventive factors of stone recurrence. METHODS A total of 322 consecutive patients with stone clearance between December 1988 and December 1995 were included. All patients were contacted for ultrasonography and were interviewed for additional information on daily intake of aspirin, NSAIDs, cholesterol lowering medication, estrogen therapy, and biliary pain during follow-up. RESULTS A total of 187 patients were still stone-free after a mean follow-up of 35 months (range: 3-89 months); 135 patients had recurrence. There was a significant association between stone recurrence and estrogen intake (p = 0.04), number of lithotripsy sessions (p = 0.0007), time until stone disappearance (p = 0.0003), and biliary pain (p < 0.0001). There was no difference in recurrence rate between solitary and multiple stones. CONCLUSIONS Long-term recurrence of gallstones after lithotripsy is high: < or = 69% after 6 yr. We found a significant association of stone recurrence with estrogen intake, number of lithotripsy sessions, and time until stone disappearance. Intake of aspirin or NSAIDs was not associated with decreased stone recurrence. Of the patients with recurrent stones, 57% had biliary pain.

Abstract
The first description of endoscopic sphincterotomy 25 years ago spearheaded the widespread use of endoscopic treatment of choledocholithiasis. It is largely accepted that common bile duct stone removal should be endoscopic rather than surgical in patients who have undergone previous cholecystectomy, in the high-risk surgical patient when the gallbladder is still present, in patients with severe acute cholangitis, in selected patients with acute biliary pancreatitis, and in special circumstances for the average risk surgical patient with suspected choledocholithiasis before laparoscopic cholecystectomy. We have summarized a number of endoscopic techniques that are used in the management of bile duct stone disease.

Abstract
Lifetime risk of gallstones in Australia is 14%-20%. The most common symptom of gallstones in either the gallbladder or bile duct is epigastric to right upper quadrant pain. Cholecystectomy is indicated for symptomatic gallbladder stones and is usually performed laparoscopically; surgery is rarely indicated for asymptomatic stones. Endoscopic retrograde cholangiopancreatography is indicated for complications of bile duct stones, such as jaundice, cholangitis or severe pancreatitis, and for postcholecystectomy symptoms of stones; bile duct stones may be removed in the same procedure via endoscopic sphincterotomy. Bile duct stones are mostly diagnosed by operative cholangiography at cholecystectomy. Open surgery is used when minimal-access techniques are dangerous, unsuitable or impossible.

Abstract
Medical treatments that dissolve or remove gallbladder stones but leave the gallbladder in situ have the disadvantage of gallstone recurrence. Little is known about the composition of recurrent stones or whether they recur true to type. In 21 patients with recurrent stones detected 5-74 months (mean +/- SEM, 26 +/- 4 months) after being rendered stone-free with dissolution therapy (N = 15) or percutaneous cholecystolithotomy (N = 6), we compared pretreatment and postrecurrence gallstone number, maximum gallstone attenuation scores measured by computed tomography (CT) and, in 13, the dissolvability of the recurrent stones with oral bile acids +/- extracorporeal shock-wave lithotripsy. Before treatment, five patients had solitary and 16 had multiple stones but on recurrence, the gallstones differed in number from the primary stones in 10 of the 21 patients. As a result of patient selection, before dissolution, the primary stones were all radiolucent with maximum CT scores of < 100 Hounsfield units (HU) (mean 45, range 10-84 HU). On recurrence, the stones were again CT-lucent in 13 of the 15 patients but were CT-dense in the remaining two (118 and 176 HU). Initially, all six patients treated by percutaneous cholecystolithotomy had radio-opaque stones, with a mean CT score of 459 (range 100-969) HU. However, on recurrence, only one had calcified stones (HU 140); the remaining five had CT-lucent stones (16-98 HU, P < 0.05). Of the 13 patients whose recurrent, plain x-ray-lucent and CT-lucent stones were treated with oral bile acids +/- lithotripsy, 12 (92%) showed evidence of gallstone dissolution. We conclude that gallbladder stones do not recur true to type in up to two thirds of patients. However, irrespective of original gallstone composition, recurrent stones are usually radio- and CT-lucent, presumed cholesterol-rich, and therefore potentially dissolvable with oral bile acids.

Abstract
BACKGROUND For symptomatic patients with gallbladder stones and a patent cystic duct who wish to retain their 'functioning' gallbladders, percutaneous cholecystolithotomy (PCCL) offers an alternative to open or laparoscopic cholecystectomy. However, there are few data on the risks and benefits of this approach or on the long-term outcome. METHODS AND RESULTS In 21 patients with symptomatic calcified gallstones, PCCL was successful (gallstone clearance) in 17 (81%). Four to 62 (median, 35) months after clearance 9 of the 17 remained symptom-free and stone-free, whereas 4 developed biliary sludge at 7, 30, 32, and 35 months, 2 of whom subsequently developed gallstones. In four other patients gallstones recurred without evidence of preceding biliary sludge at 9, 16, 19, and 27 months, corresponding to an actuarial gallstone recurrence rate at 36 months of 53.4 +/- SEM 15.1%, and a combined stone/sludge recurrence rate of 63.4 +/- 13.5%. CONCLUSIONS PCCL is moderately effective but, because of the frequency of complications and sludge/stone recurrence, is likely to have only a limited residual role in the era of laparoscopic cholecystectomy.

Abstract
BACKGROUND/AIMS Altered gallbladder motility is regarded as one of the important factors involved in the formation and recurrence of gallstones. Previous studies have suggested that cisapride increases postprandial gallbladder contraction and may therefore be theoretically useful in preventing stone recurrence. The aim of our study was therefore to investigate the effect of cisapride on gallbladder motility in stone-free patients after extracorporeal shock-wave lithotripsy, as compared to healthy volunteers pair-matched for age and sex. METHODS Each subject received cisapride or placebo in a double-blind, cross-over, random order. Gallbladder volumes were measured by ultrasonography in the fasting state and after intake of a standard liquid meal. Plasma cholecystokinin levels were determined by radioimmunoassay. RESULTS Fasting gallbladder volumes were smaller in patients as compared to volunteers (20.7 +/- 1.3 ml vs. 46.0 +/- 9.2 ml; p < 0.05) but were not modified by cisapride (21.1 +/- 1.7 ml vs. 58.6 +/- 11.3 ml). The maximal postprandial decrease in gallbladder volume was similar in patients and volunteers (64.5 +/- 12% vs. 62 +/- 10%; NS) and was not significantly altered by cisapride (59 +/- 9.4% vs. 54 +/- 9%; NS). In patients, cisapride increased integrated postprandial gallbladder volume by accelerating gallbladder refilling as compared to placebo by 37 +/- 15% (p < 0.05). Integrated cholecystokinin plasma levels were similar in patients and volunteers and were 13.4 +/- 4.7% higher after cisapride as compared to placebo (p < 0.05). CONCLUSIONS The results of this study suggest that cisapride does not alter postprandial gallbladder contraction but accelerates gallbladder refilling in patients free from gallstones after extracorporeal shock-wave lithotripsy. This effect of cisapride is probably due to an acceleration of gastric emptying also causing a secondary enhanced cholecystokinin release.

Abstract
Cholelithiasis affects 10-15% of the adult population in Western society, and about 75% of gallstones are of cholesterol type. Hepatic hypersecretion of cholesterol with the formation of instable cholesterol-rich vesicles in bile, an imbalance between nucleation-inhibiting and nucleation-promoting proteins with further aggregation of cholesterol crystals in a gallbladder with a motility defect (stasis), all play a role in the pathogenesis of cholesterol gallstones. Experimental animal models suggest that gallstone formation can be prevented by improving gallbladder emptying. Thus, a better understanding of the causes underlying the impaired gallbladder motor function in patients with gallstones might lead to the selection of therapeutic approaches for those individuals who are at increased risk for the formation or recurrence of gallstones. The present article focuses on current concepts and theories on the pathogenesis of cholesterol gallstones with emphasis on the gallbladder motility defect. Several treatment strategies for the correction of gallbladder hypomotility are also discussed.

Abstract
To estimate patient preferences for gallstone-related treatments and outcomes, and assess how preferences vary by patient characteristics and scaling technique, the authors randomly assigned 40 patients without gallstones to interviews based on a rating scale (n = 22) and a standard gamble (n = 18). The patients assigned preference values (possible values 0 to 1) to open cholecystectomy (mean 0.45 by rating scale, 0.78 by standard gamble), laparoscopic cholecystectomy (0.71, 0.91), extracorporeal shock-wave lithotripsy (0.77, 0.89), acute cholecystitis (0.36, 0.77), lifetime biliary colic (0.41, 0.71), postcholecystectomy syndrome (0.43, 0.79), asymptomatic stone necessitating treatment with bile acids (0.76, 0.96), and surgical scar (0.79, 0.998). Preferences varied little by age, gender, or race. Standard gamble values were highly correlated with, but significantly greater than, rating scale values. The authors conclude that patients' preferences for gallstone-related conditions generally are significantly less than one, and differ markedly by the scaling technique used to derive them. These results should be considered when patient preferences are incorporated into analyses of gallstone treatments.

Abstract
Using radiological interventional techniques the gall bladder can be cleared of stones with a high success rate. As with any treatment option that leaves the gall bladder in situ there is an accompanying risk of stone recurrence, which is currently unknown for the radiological method. One hundred patients were studied prospectively to determine the recurrence rate of stones and clinical outcome after successful percutaneous cholecystolithotomy. Follow up included both clinical assessment and ultrasound examination at 3, 6, and 12 months and then annual intervals thereafter. The overall stone recurrence rate was 31% at a mean follow up of 26 months (range, 3-50 months). By actuarial life table analysis, the cumulative proportion of gall stone recurrence was 7, 19, 28, 35, and 44% at 6, 12, 24, 36, and 48 months respectively. Of the 31 patients with recurrent stones; 17 remain asymptomatic, seven have experienced biliary colic, two abdominal pain, three non-specific upper gastrointestinal symptoms, and two jaundice secondary to common duct stones. Thirteen of the stone free patients have remained symptomatic; six with abdominal pain and seven with nonspecific upper gastrointestinal symptoms. Eight patients have subsequently had a cholecystectomy. No significant difference was found between the sex of the patient or the number of stones before treatment and the stone recurrence rates. The cumulative stone recurrence rate was significantly less in the 56 patients who received adjuvant chemolitholysis (p < 0.05). These data show that stone recurrence after successful percutaneous cholecystolithotomy occurs in the minority, and is usually asymptomatic. It is concluded that the technique remains justified in the management of selected patients with gall stones.

Abstract
Extracorporeal shockwave lithotripsy (ESWL) is a feasible procedure for the treatment of gallbladder stones in humans. Well-selected patients can achieve stone-free rates in a high percentage. With the gallbladder in situ, these patients are at risk of stone recurrence. There is considerable evidence that aspirin prevents cholesterol gallstone formation in animal models and may prevent gallstone recurrence in man. We attempted to clarify the risk of gallstone recurrence after successful piezoelectric lithotripsy in patients taking either low-dose aspirin or no medication. The first 45 patients shown to be completely free from stones after ESWL were randomized into two groups. One group received 100 mg aspirin daily; the other group did not receive any further medical therapy. Patients were further examined on an average of 19.6 months and 21.9 months, respectively. In the aspirin group the recurrence rate was 18.2%, whereas 21.7% of the patients in the control group developed recurrent stones. Seventy-eight per cent of these patients also had a recurrence of biliary pain. By life-table analysis we had, after a follow-up period of 24 months, a stone recurrence rate of 25% (+/- 11) in the aspirin group and 34% (+/- 14) in the control group. Our results indicate that recurrence prophylaxis remains one of the central questions in ESWL. In this preliminary study, 100 mg of aspirin daily was not able to reduce the recurrence rate after successful ESWL. Further studies will have to show whether higher doses of aspirin or other ways of preventing gallstone after ESWL are possible.

Abstract
Using a modified electromagnetic lithotripter (Siemens), extracorporeal shock wave lithotripsy (ESWL) was performed in 260 patients with gall bladder stones. Exclusion criteria for treatment were a non-functioning gall bladder, subcostal gall bladder location, and multiple stones occupying more than three quarters of the gall bladder volume. Stone pulverisation was the end point of ESWL. The number of shock wave discharges and sessions was not limited. Pulverisation was achieved in 250 patients (96.1%) after a median of three ESWL sessions (range 1-21). The number of sessions required depended upon stone composition and burden. More than three sessions were required in 60.2% of patients with calcified stones compared with 35.9% of patients with non-calcified stones (p < 0.001). 65.8% of patients with stones measuring more than 30 mm in total diameter required more than three sessions compared with 42.9% of patients with a stone burden less than 30 mm (p < 0.01). At 18-24 (8-12) months follow up, stone clearance was achieved in 94.3% (80.4%) of patients with non-calcified stones, compared with 89.5% (76.8%) in patients with calcified stones and in 75% (71.4%) of patients with a total stone diameter more than 30 mm compared with 95.7% (80.4%) for patients with a total stone diameter less than 30 mm (p < 0.05). ESWL related complications (gross haematuria) occurred in three patients. Thirty six (13.8%) patients experienced biliary colic; four had cholecystectomy, and five endoscopic papillotomy because of common bile duct obstruction. Stone recurrence was seen in 5.3% of patients over a follow up period of up to two years (median 16.6 months).

Abstract
Laparoscopic cholecystectomy is the treatment of choice for symptomatic cholelithiasis. Medical treatment is indicated for patients who are not fit or are afraid of surgery. For any form of medical treatment to be effective gallstones must be cholesterol rich, thus radiolucent, and the cystic duct must be patent, as indicated by gallbladder opacification on oral cholecystography. Three forms of medical treatment are currently available for clinical use--oral bile acids, bile acids as adjuncts to lithotripsy and contact dissolution using methyltertbutylether. The choice of treatment depends mainly on gallstone size. Gallstones < 6 mm in diameter are best treated with oral bile acids, chenodeoxycholic acid 15 mg/kg/day or ursodeoxycholic acid 10 mg/kg/day given alone or in combination (5 mg/kg/day each). Careful patient selection and bedtime administration of the whole daily bile acid dose enhance treatment, and may achieve up to 75% complete dissolution annually. Single stones < 30 mm in diameter or multiple stones (n < 3) are best treated with lithotripsy combined with oral bile acid for dissolution of fragments. Annual dissolution rates are about 80 and 40% for single and multiple stones, respectively. Stones of any size and number can be dissolved by direct contact dissolution using methyltertbutylether. Dissolution has been reported to be complete in almost 100% of stones, but debris is frequently left behind in the gallbladder. Following dissolution using any form of treatment, gallstones recur in about 50% of patients, and cannot be reliably prevented by low dose bile acid or dietary manipulations. Failing prevention, early detection and retreatment of recurrent stones is the best alternative option as a long term strategy.

Abstract
BACKGROUND/AIMS Supersaturation of bile with cholesterol, rapid nucleation of cholesterol crystals, and/or incomplete emptying of the gallbladder are believed to be required for gallstone formation. The importance of these factors for the recurrence of gallbladder stones was studied. METHODS Twenty patients, untreated after successful shock wave therapy, were studied in a matched case-control design for bile acid turnover, composition of duodenal bile, and gallbladder emptying. In 10 of them, gallstones had recurred within 12 +/- 2 months (X +/- SEM); the other 10 had been free of stones since 22 +/- 3 months. RESULTS In each group, duodenal bile was supersaturated with cholesterol in 8 of 10 patients and showed abnormal nucleation time of cholesterol crystals in half of the patients. Patients with recurrent stones had smaller pool sizes of cholic acid (-43%) and enhanced conversion of cholic acid to deoxycholic acid. The odds for stone recurrence were ninefold increased in the presence of excessive deoxycholic acid (exceeding cholic acid) in the bile acid pool or incomplete emptying of the gallbladder (residual volume > 5 mL) in response to cholecystokinin. The odds ratio was over 20-fold increased when incomplete emptying of the gallbladder coincided with supersaturated bile or with excessive deoxycholic acid. CONCLUSIONS Enhanced conversion of cholic acid to deoxycholic acid and incomplete emptying of the gallbladder could be important cofactors for the recurrence of gallstones.

Abstract
BACKGROUND/AIMS The long-term outcome of nonoperative gallstone therapy depends on both absence of stones and absence of biliary pain. The aim of the present study was to determine the rate of stone recurrence and the rate of symptoms within 5 years after successful shock wave lithotripsy combined with bile acid therapy. METHODS One hundred consecutive patients (single stones, n = 89; 2 or 3 stones, n = 11) were followed up for a median of 4.3 years after stone disappearance and discontinuation of bile acids. RESULTS Twenty-three of the 100 patients developed recurrent stones. Calculated by actuarial analysis, the recurrence rate was 7% +/- 3%, 11% +/- 3%, 13% +/- 4%, 20% +/- 5%, and 31% +/- 7% (mean +/- SD) at 1, 2, 3, 4, and 5 years, respectively. The recurrent stones were small (6 +/- 5 mm) and were associated with recurrent biliary pain in 14 (61%) of the 23 patients. Repeated shock wave lithotripsy and/or bile acid medication resulted in stone disappearance in only 10 of 20 patients with recurrence. CONCLUSIONS The long-term rate of stone recurrence after lithotripsy of primarily solitary gallbladder calculi is lower than expected from post-bile acid dissolution trials. Recurrence of stones frequently is associated with recurrence of biliary pain.

Abstract
The British/Belgian Gall Stone Study Group (BBGSG) post-dissolution trial was a prospective, multicentre, randomised, double blind trial of: (i) low dose ursodeoxycholic acid, (ii) placebo, and (iii) a high fibre, low refined carbohydrate diet in the prevention of gall stone recurrence in patients with complete gall stone dissolution. Further aims included establishing the timing and frequency of recurrence and its association with biliary symptoms, a comparison of the sensitivity of ultrasonography v oral cholecystectography in detecting recurrent stones, and a search for risk factors predicting recurrence. Ninety three patients entered the study, and 82 were followed up for up to five years (mean (SEM) 28 (1.5) months) with six monthly ultrasonography and yearly oral cholecystectography. There were 21 recurrences (26 by oral cholecystectography or ultrasonography, or both), only two of which were symptomatic, which were detected between 12 and 42 months after trial entry. This corresponded to an actuarial recurrence rate of 33.9 (7.0%) by lifetable analysis at 42 months and subsequently. There were four recurrences in the ursodeoxycholic acid, six in the placebo, and 11 in the diet groups, corresponding to 21.9 (9.9)%, 27.4 (10.1)%, and 45.8 (12.4)% respectively at 42 months by lifetable analysis (NS). Variables including age, obesity, menopausal state, pregnancy, and oestrogen containing drugs were not shown to affect recurrence rate. Men had more frequent recurrence than women (NS). Patients who had had multiple stones experienced more recurrences than did those with single stones (NS). Recurrence did not occur in patients who took non-steroidal anti-inflammatory drugs (NSAIDs) (p < 0.02). The stone free interval between stone dissolution and trial entry proved to be important--those stone free > nine months had a recurrence rate of only 12.7 (6.0)% at 42 months compared with 55.4 (12.5)% in those stone free < nine months (p < 0.01). There was imbalance between the ursodeoxycholic acid and placebo groups for this factor, and after applying a statistical correction, the adjusted recurrence rate in the ursodeoxycholic acid group was 15% compared with 30% in both placebo and diet groups (NS). These data suggest that after medical dissolution, the risk of gall stone recurrence is not reduced by a high fibre, low refined carbohydrate diet: it may be lowered, but not abolished, by low dose ursodeoxycholic acid.

Abstract
Since the early 1980s extracorporeal shock wave lithotripsy (ESWL) has partially replaced major operative procedures in various fields of surgery. In the interest of the patient, it is important to determine the exact role of ESWL in surgery. Comparing our own prospectively followed patients with other patient series, we have tried to assess this role. We treated 133 patients with cholecystolithiasis, 80 patients with choledocholithiasis, and 17 patients with pancreatic stones using a second-generation lithotriptor, the Siemens Lithostar (Siemens, Erlangen, Germany). The results suggest a limited role of ESWL for cholecystolithiasis, in which it is reserved for patients with high operative risk and patients who reject an operation. For choledocholithiasis ESWL seems to become an integral part of the treatment in the elderly patient in whom endoscopic stone removal proved impossible. Finally, ESWL could become a first option for the treatment of intractable pain in patients with chronic calcifying pancreatitis.

Abstract
OBJECTIVE This study evaluated, in a large, heterogeneous population, the outcome of open cholecystectomy as it is currently practiced. SUMMARY BACKGROUND AND DATA: Although cholecystectomy has been the gold standard of treatment for cholelithiasis for more than 100 years, it has recently been challenged by the introduction of several new modalities including laparoscopic cholecystectomy. Efforts to define the role of these alternative treatments have been hampered by the lack of contemporary data regarding open cholecystectomy. METHODS A population-based study was performed examining all open cholecystectomies performed by surgeons in an eastern and western state during a recent 12-month period. Data compiled consisted of a computerized analysis of Uniformed Billing (UB-82) discharge analysis information from all non-Veterans Administration (VA), acute care hospitals in California (Office of Statewide Planning and Development [OSHPD]) and in Maryland (Health Services Cost Review Commission [HSCRC]) between January 1, 1989, and December 31, 1989. This data base was supplemented with a 5% random sample of Medicare UB-82 data from patients who were discharged between October 1, 1988, and September 30, 1989. Patients undergoing cholecystectomy were identified based on diagnosis-related groups (DRG-197 and DRG-198), and then classified by Principal Diagnosis and divided into three clinically homogeneous subgroups: acute cholecystitis, chronic cholecystitis, and complicated cholecystitis. RESULTS A total of 42,474 patients were analyzed, which represents approximately 8% of all patients undergoing cholecystectomy in the United States in any recent 12-month period. The overall mortality rate was 0.17% and the incidence rate of bile duct injuries was approximately 0.2%. The mortality rate was 0.03% in patients younger than 65 years of age and 0.5% in those older than 65 years of age. Mortality rate, length of hospital stay, and charges were all significantly correlated (p < 0.001) with age, admission status (elective, urgent, or emergent), and disease status. CONCLUSIONS These data indicate that open cholecystectomy currently is a very safe, effective treatment for cholelithiasis and is being performed with near zero mortality. The ultimate role of laparoscopic cholecystectomy needs to be defined in the context of current and contemporary data regarding open cholecystectomy.

Abstract
We evaluated the effect of ursodeoxycholic acid on the metastability of human bile as reflected by nucleation time and also assessed the mechanism of its action in an ultrastructural study. Ursodeoxycholic acid significantly prolonged the nucleation time of gallbladder bile from cholesterol gallstone patients without causing either drastic changes in the distribution of cholesterol between the nonmicellar and micellar fractions of bile or biliary cholesterol desaturation. Gel permeation chromatography resolved two distinct components of the nonmicellar fraction: vesicles and phospholipid lamellae (identified by electron microscopy). Nonmicellar cholesterol was predominantly carried by vesicles in the bile of untreated gallstone patients, whereas it was chiefly carried by phospholipid lamellae in patients treated with ursodeoxycholic acid. Furthermore, phospholipid lamellae from untreated gallstone patients showed rapid transformation and cholesterol microcrystal formation within seven days, whereas the lamellae from ursodeoxycholic acid-treated patients were stabilized and showed little change. On the other hand, biliary mucin concentration was reduced by the treatment with ursodeoxycholic acid. These findings suggest that ursodeoxycholic acid stabilizes phospholipid lamellae and consequently prolongs nucleation time. It is also possible that the reduction of biliary mucin plays a role in this process.

Abstract
The management of gallstone diseases has been revolutionized in less than 2 years by the advent of laparoscopic cholecystectomy (LC). However, the rapid adoption of LC has occurred without comparative randomized trials with other available therapies. Thus, the evaluation of LC versus other therapies can only be based on case series. The criteria used for this evaluation are clinical effectiveness, cost-effectiveness, and the patient's level of acceptance and satisfaction with the procedure. The techniques of both LC and open cholecystectomy (OC) have the advantage over other approaches, such as extracorporeal shock-wave lithotripsy or bile acid therapy, of eliminating not only the gallstones but also the gallbladder, thereby preventing recurrence of the disease. Additionally, medical therapies are effective in only a subgroup of patients. Since the complications of surgery are more frequent and more severe in older patients and, due to life expectancy, the risk of recurrence is lower in this population, cost-effectiveness analyses have shown that medical therapies may be preferable in older patients in the subgroup eligible for the respective medical therapies. Compared with OC, LC results in a reduction in hospital stay and time to return to work, in lower cost, and in higher patient satisfaction with the procedure. However, a major concern with the laparoscopic approach has been an increase in the incidence of bile duct injury, particularly during the learning phase of the procedure. Clearly, this problem must be solved. The development of training courses in laparoscopy and the adoption of rigorous criteria for ductal identification are critical in preventing such injuries. Bile duct injury can probably be reduced at least to the level of OC (about 1 in 1,000). Acute cholecystitis may also be treated by LC, but the safety and timing of surgery should be conclusively evaluated. Patients with gallbladder stones and choledocholithiasis are usually treated by endoscopic sphincterotomy either before or soon after laparoscopic surgery. Laparoscopic techniques of common bile duct exploration that will obviate the need for endoscopic sphincterotomy are in the developmental stages. When such a technique is available, comparative trials with endoscopic sphincterotomy will be necessary to assess the best approach.

Abstract
Extracorporeal shock-wave lithotripsy (ESWL) has been applied to patients with gallstones since the mid-1980s. Lithotriptors differ by their means of shock-wave generation, the mechanisms by which they are coupled to the patient, and their imaging systems. Entry in most treatment protocols is limited to symptomatic patients with one to three radiolucent stones having a diameter of 30 mm or less and a functioning gallbladder according to oral cholecystography. Treatments are given on an out-patient basis using intravenous analgesia and include adjuvant bile acid therapy. Deaths have not been reported, and the incidence of serious complications, related to the presence of fragments in the biliary system, is low. The studies show that ESWL is a safe and effective treatment for patients with a single gallstone less than or equal to 20 mm in diameter, but the efficacy for larger single stones and multiple stones is poor. To date, the Food and Drug Administration has not approved lithotriptors for the treatment of gallstones in the United States.

Abstract
To establish the value of ultrasound (US) in the follow-up of patients treated with extracorporeal shockwave lithotripsy (ESWL), the results of 484 US examinations of 87 patients were analyzed and related to the results of ESWL. Reliability of US in assessing efficacy was investigated by comparing consecutive US examinations. Unreliable US results were found in 36 patients (41%); in 7 patients US failed to demonstrate fragments. In nine patients (10%) unreliable US findings contributed to delayed retreatment with ESWL. To prevent errors in treatment regimen, verification of US findings is advised in case no fragments or fragments < 5 mm are found. In 22 patients (25%) US findings appeared indicative of hampered stone migration. Only 2 of these 22 patients (9.1%) became free of stones, compared with 32 of the remaining 65 patients (49.3%) (p < 0.01), even though both groups had similar initial stone characteristics and similar time of follow-up. US findings such as a contracted gallbladder or a common bile duct > 7 mm therefore indicate poor efficacy of ESWL.

Abstract
Recent conservative gallstone treatments provide rapid relief from symptoms, but all have a potential for stone recurrence. They are indicated in patients who are unfit or unwilling to undergo cholecystectomy. Wider application will depend on selection of patients who are at least risk of recurrence, or on development of effective prophylactic strategies.

Abstract
During a period of 24 months 693 consecutive patients with symptomatic gall bladder stones (526 males, 167 females; mean age 51 years, range 18-89) were treated by extracorporeal shock wave lithotripsy with a Piezolith 2300. The procedure was carried out on an out-patient basis without analgesics or sedatives. Concomitant chemolitholytic treatment (ursodeoxycholic and chenodeoxycholic acid 7.5 mg/kg/day each) was administered until three months after total fragment clearance for a maximum therapy period of 1.5 years. In 601 patients with radiolucent stones complete clearance of all fragments was obtained after three, six, 12, and 18 months in respectively 20, 41, 64, and 78%. Actuarial analysis of the subgroups according to the stone mass (size and number) selected an ideal patient population with solitary stones less than 20 mm diameter (84% stone free after one year). The results are significantly less good when the greater the number of stones or their maximal diameter increases. Treatment was interrupted in 3.6% of the patients. In 90 sludge or fragments remain present. Twenty five patients were lost to follow up for non-biliary reasons. Stone recurrence was 5.7% at one year and was observed both in patients with solitary and multiple stones. A cost effectiveness analysis suggests that laparoscopic cholecystectomy is the most effective and economic solution, although extracorporeal shock wave lithotripsy for solitary radiolucent stones less than 2 cm is cheaper than conventional cholecystectomy. Extracorporeal shock wave lithotripsy for multiple stones is the most expensive and least effective option.

Abstract
Within the past 7 years, gallbladder lithotripsy by shockwaves has been proven to be a safe and effective non-invasive therapy for selected patients with gallstone disease. While regulatory decisions prevent shockwave therapy from being used more frequently in the USA, the number of patients treated in Europe and Asia is increasing constantly. At our institution, a relatively constant number of about 250 new patients per year have been treated since 1988 (Figure 4). About 20% of patients with gallstones are suitable for shockwave therapy according to present criteria. The rate of evacuation of all fragments is determined by the initial stone number and stone size, the success at stone fragmentation, adjuvant bile acid dissolution therapy, and gallbladder contractility. In contrast to laparoscopic cholecystectomy (Dubois et al, 1989; Perissat et al, 1989; Southern Surgeons Club, 1991), shockwave therapy does not require general anaesthesia. And in contrast to direct contact dissolution therapy of gallbladder stones using MTBE (Thistle et al, 1989), lithotripsy is non-invasive. In the majority of patients, complete fragment disappearance takes several months. Preliminary analyses of the cost-effectiveness of lithotripsy have revealed that lithotripsy, including retreatments and bile acid medication for recurrent stones, costs about as much as open cholecystectomy (Rothschild et al, 1990; Bass et al, 1991). The ideal patient for gallbladder lithotripsy has a single radiolucent stone < or = 20-25 mm in diameter in a functioning gallbladder (Figure 1). In patients with such stones, nearly all studies have confirmed a favourable outcome with rapid clearance of all fragments and a relatively low rate of stone recurrence. For carefully selected patients, extracorporeal shockwave lithotripsy is therefore an attractive non-invasive therapy.

Abstract
Direct contact dissolution using MTBE is a safe, effective treatment for many patients with cholesterol gallstones when performed by clinicians experienced with this technique. This may be the treatment of choice for many patients at high risk for general anaesthesia or surgery. Cholecystostomy using local anaesthesia with subsequent stone extraction is an alternative requiring prolonged catheter drainage, and is associated with some risk and discomfort (Hawkyard et al, 1990). Most experts concur that laparoscopic cholecystectomy cannot be performed safely and comfortably without general anaesthesia under most circumstances. A second small population of patients are inordinately apprehensive about general anaesthesia or surgical removal of their gallbladder and refuse standard therapy in spite of recurrent biliary symptoms. Although direct contact dissolution is generally well tolerated, it may require several days of paramedical attention with medical supervision. This procedure will be most efficiently, effectively and comfortably performed by an experienced team and is, therefore, probably best provided by referral centres with physicians sufficiently interested in the treatment of biliary tract stone disease to develop expertise with this method.

Abstract
The risk of gallstone recurrence following non-surgical treatment has been overestimated in the past for two reasons: (1) diagnosis of primary gallstone dissolution was based on oral cholecystography; and (2) gallstone recurrence was expressed as a cumulative recurrence rate. Results based on better methodologies for diagnosis of gallstones (ultrasonography) and for calculation of results (life-table analysis) have indicated that gallstones recur in about 50% of patients, and that the risk of recurrence is confined mainly to the first 5 years after dissolution. Pretreatment gallstone characteristics, but not patient characteristics, are important risk factors for gallstone recurrence. Multiple stones are more likely to recur than solitary stones, a phenomenon attributable to the presence of a potent pronucleating factor in the bile of patients with multiple stones. This observation, and the finding that NSAID administration may reduce gallstone recurrence via inhibition of mucin secretion, suggests that the nucleation defect might be a key factor in the pathogenesis of recurrent gallstones. Prophylaxis with low-dose CDCA or UDCA has proven ineffective for preventing gallstone recurrence, although it may reduce it. Since the majority of recurrent gallstones are small when first seen because of regular ultrasonographic follow-up, multiple, radiolucent and in functioning gallbladders, they are amenable to bile acid retreatment, and intermittent bile acid therapy is probably a viable strategy for long-term management of cholesterol cholelithiasis.

Abstract
Oral cholelitholytic bile acid therapy has become established treatment for selected patients with cholesterol gallstones. The treatment finds its clinical application both alone and in combination with ESWL. UDCA alone or, less commonly, a combination of this bile acid with CDCA is used. Optimal results can be expected only in carefully selected patients. Bile acid dissolution therapy is most successful in patients with radiolucent gallstones which are < or = 0.5 cm in diameter or are shown by OCG to be floating. Dissolution is seldom seen when the stones are > 1 cm in size. Cholelitholytic treatment in combination with ESWL yields optimal results in single radiolucent gallstones which are not greater than 2 cm. ESWL thus makes it possible to use medical treatment effectively in single 1-2 cm gallstones when bile acids alone would not be successful. Bile acid treatment is extremely safe, especially if UDCA is given without the addition of CDCA.

Abstract
Piezoelectric lithotripsy with the EDAP LT-01 machine combined with adjuvant bile acid therapy results in complete clearance of radiolucent gallstones in selected patients. We assessed stone recurrence rate in 84 patients with complete clearance of stone fragments and followed up at least 12 months after cessation of bile acid therapy (mean 17 months, range 12-33). Fifty-four patients had a solitary stone and 30 multiple stones. Bile acid therapy was continued for 3 months after complete fragment stones clearance which was ascertained by two consecutive ultrasound examinations. Stone recurrence was assessed by ultrasonography at 6 and 12 months, and then at least once a year. Gallstone recurrence occurred in 5 patients (6%) between 9 and 12 months with no further recurrence up to 33 months. The rate of recurrence at one year was 3.7% in patients with a solitary stone and 10% in patients with multiple stones. Only one patient with stone recurrence had recurrent biliary pain. We concluded that early gallstone recurrence rate after successful lithotripsy seems to be low in patients with solitary stones.

Abstract
Between January 1988 and December 1990, 283 patients with symptomatic gall stones were referred for non-operative treatment. After ultrasound scanning including a functional assessment, 220 (78%) patients were found to be suitable for percutaneous cholecystolithotomy. Of these, 113 underwent the procedure including 10 in whom extracorporeal shock-wave lithotripsy or methyl tert-butyl ether therapy had failed. Forty four patients underwent extracorporeal shockwave lithotripsy, methyl tert-butyl ether therapy or rotary lithotripsy, 46 chose laparoscopic cholecystectomy or minicholecystectomy and 27 declined treatment. Percutaneous cholecystolithotomy was successfully performed in 100 patients. Thirty four patients were a high operative risk and 14 presented with an acute complication of gall stone disease. Complications developed in 15 patients, all of whom were managed conservatively and most occurred during development of the technique. Outcome has been assessed clinically and by ultrasound scanning in 92 patients with a median follow up period of 14 months (six to 37 months). Seventy nine per cent were completely cured of their symptoms. Ninety three per cent of gall bladders were shown to be functioning and nine (9.8%) contained stones, although five of these are believed to have developed from residual fragments. Percutaneous cholecystolithotomy is a safe, non-operative treatment for symptomatic gall stones and enabled the patient to fully recover within two to three weeks; it has a definite role in the management of the elderly and high risk patient but its use for the treatment of other groups is likely to remain controversial.

Abstract
The action of the motilin receptor agonist erythromycin on human gallbladder contraction, measured by ultrasound, both in normal subjects and those with gallstone disease was studied. In 17 normal subjects, oral erythromycin administration (500 mg; vs. placebo) reduced fasting gallbladder volume at 2 hours (26.2 vs. 19.0 mL; P less than 0.001), and postprandial residual gallbladder volume (9.0 vs. 4.4 mL; P less than 0.001) and the rate constant of gallbladder emptying following the meal was significantly increased. Erythromycin also reduced fasting and residual gallbladder volumes in 13 patients with gallstone disease: in 6 who underwent cholecystolithotomy, fasting volume was 29.5 vs. 22.3 mL (P less than 0.05) and residual volume was 17.7 vs. 6.5 mL (P less than 0.05), and in 7 with gallstones in situ, fasting volume was 23.8 vs. 14.3 mL (P less than 0.05) and residual volume was 17.2 vs. 5.0 mL (P less than 0.05). In 7 of 8 subjects with gallstones and impaired gallbladder emptying, the gallbladder emptied normally following administration of erythromycin, and in 3 of the other 5 gallstone subjects gallbladder emptying was increased. In 6 normal subjects given erythromycin three times weekly for 1 month, the effect was maintained (fasting volume, 18.8 mL, P less than 0.001; residual volume, 3.7 mL, P less than 0.001). Oral erythromycin significantly reduces fasting and postprandial residual gallbladder volumes in both normal subjects and subjects with gallstones and reverses the gallbladder motility defect found in a proportion of subjects with gallstones. This effect is maintained for a month in normal subjects.

Abstract
Patients with multiple cholesterol gallbladder stones have been found to be at a higher risk for the recurrence of gallstones after successful nonsurgical treatment than those with a solitary stone. Cholesterol gallstone recurrence, like primary gallstone formation, probably involves a triple defect with supersaturation, abnormally rapid nucleation of cholesterol in bile and altered gallbladder motor function. We investigated whether the increased recurrence rate of patients with multiple stones might be caused by more rapid nucleation. Therefore the time required for cholesterol monohydrate crystals to appear in ultracentrifuged bile of patients with solitary (n = 71) or multiple (n = 42) cholesterol gallstones was determined. The cholesterol nucleation time was significantly (p less than 0.01) longer in the bile from patients with solitary stones (less than 1 to 16 days, median = 2.0 days) than in the bile from patients with multiple stones (less than 1 to 8 days, median = 1.0 days). Moreover, 15 of 71 (21.1%) patients with solitary cholesterol stones but only 1 of 42 (2.4%) patients with multiple cholesterol stones showed a normal (greater than 4 days) nucleation time. However, no difference in the cholesterol saturation index was found between the bile samples from patients with solitary stones and the bile samples from patients with multiple stones (1.55 +/- 0.65 vs. 1.54 +/- 0.59, mean +/- S.D., respectively). The more rapid cholesterol nucleation in gallbladder bile may, therefore, be the major risk factor causing the higher percentage of stone recurrence in patients with multiple cholesterol stones as compared with patients with solitary cholesterol stones.

Abstract
Extracorporeal shockwave lithotripsy (ESWL) and litholytic therapy were used in 100 patients over a period of 16 months. ESWL was carried out with a Lithostar Plus and chenodeoxycholic acid was used as the lytic agent, given until 3 months after complete disappearance of stones. Within a period of 8-12 months, stones disappeared completely in 82 per cent of the patients who had a single stone less than or equal to 20 mm in diameter and in 50 per cent of those with a single stone greater than 20 mm in size or with multiple stones. Complications requiring surgery developed in five patients: three had acute cholecystitis and two developed acute pancreatitis. Of the patients in whom complete stone clearance was achieved, two of 11 followed up developed recurrence of stones 4 months after cessation of lytic therapy.

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
To determine the potential role of extracorporeal shock wave lithotripsy (ESWL) in the treatment of symptomatic gallstone patients in France, a simulation model evaluated the health and economic effects of three different treatment strategies. Decision analysis of conventional cholecystectomy alone and either of two strategies using a combination of biliary lithotripsy and conventional cholecystectomy reveals that a strategy employing biliary ESWL results in a significant number of successfully treated patients, thus avoiding the risks and costs of abdominal surgery. Moreover, cost analysis shows that expanding the use of lithotripsy to all patients for whom the procedure is indicated increases the average cost per successfully treated patient, but, more importantly, decreases the overall costs incurred by the cohort. From a societal viewpoint, a policy using biliary ESWL in appropriate patients is superior to one of cholecystectomy alone, from both clinical and economic perspectives.

Abstract
This article reviews selected aspects of the non-surgical/minimally invasive treatments of gallbladder stones (GBS) and discusses briefly the residual role of these treatments in the era of laparoscopic cholecystectomy. In patients with specific, gallstone-related symptoms who wish to retain their 'functioning' gallbladders, there are at least six different management options. They range from rapid but invasive to slow but safe: i) the rotary lithotrite; ii) percutaneous cholecystolithotomy; iii) percutaneous transhepatic or iv) endoscopic retrograde cannulation of the gallbladder followed by instillation (manual or pump-assisted) of contact solvents; v) extracorporeal shock-wave lithotripsy + adjuvant bile acids and; vi) oral bile acids alone. The recommended investigation sequence is i) ultrasound (to diagnose the presence of GBS), followed by ii) oral cholecystography (to assess cystic duct patency, gallbladder anatomy and GBS size, number, lucency, buoyancy, and contour), and iii) regional computed tomography scanning of the gallbladder (to predict stone composition and dissolvability and to plan routes of access to the gallbladder). The decision-making steps are i) choice of some form of active treatment versus no treatment (other than observation); ii) in those with specific symptoms and a patent cystic duct who opt for active treatment, to choose between removing versus retaining the gallbladder; and iii) in those who wish to retain their 'functioning' gallbladder, to offer and select the most appropriate of the alternative options. In conclusion, despite the excellence of laparoscopic cholecystectomy, there remains a place for the non-surgical/minimally invasive approaches in a carefully selected minority of symptomatic GBS patients. Although GBS may recur in approximately 50% of patients, the recurrent stones are often asymptomatic, can be detected 'early' by follow-up ultrasound, and are easily treated. Ultimately, the aim of gallstone research must be to prevent not only recurrent but also primary GBS formation, which would obviate the need for both medical and surgical treatment.
