Gastroenterol Res Pract 2012; 2012:159438. [PMID: 22611378 PMCID: PMC3352327 DOI: 10.1155/2012/159438] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2011] [Revised: 02/01/2012] [Accepted: 02/01/2012] [Indexed: 11/25/2022] Open
Abstract
Background/Aims. The aim of this study was to compare the effects of ursodeoxycholic acid (UDCA) alone and UDCA plus domperidone on dissolution of solitary or multiple gallstones. Methods. Fifty-three patients with cholesterol gallstones were randomized into three treatment groups: group I (n = 22) was given UDCA (15 mg/kg/day) alone and group II (n = 18) was treated with domperidone (30 mg/day) in addition to UDCA. The control group (n = 13) was followed without a medical treatment. Gallbladder volumes and ejection fractions were measured sonographically in all patients before and after treatment. Results. After 12 months of treatment, stone dissolution was found in 9 (40.9%) of the patients in group I and 7 (38.8%) of the patients in group II. The difference was statistically significant compared to controls in both treatment groups (P < 0.05) but the two groups did not show a difference between each other (P > 0.05). All the patients that achieved dissolution had multiple gallstones except for one patient with a solitary stone in group I. Neither monotherapy of UDCA nor the combination with domperidone affected the ejection fraction of gallbladder. Conclusions. Combination with domperidone did not potentiate the efficacy of UDCA. It has been observed that both UDCA alone and UDCA plus domperidone treatment did not affect ejection fraction of gallbladder.

Abstract
Mucin is a high-molecular-weight glycoprotein that is synthesized, stored, and secreted by epithelial mucosal cells, especially goblet cells. Mucin proteins are derived from many different genes, termed MUC genes. Several lines of evidence point to a biological role for mucin in cholesterol gallstone formation. Mucin serves as a pronucleating agent in experimental and human gallstone disease, and the hydrophobic binding sites in the polypeptide core of mucin may provide a favorable environment for nucleation of cholesterol monohydrate from supersaturated bile. Mucin hypersecretion is prominent in many animal models of gallstone formation, thus contributing by its pronucleating quality to gallstone formation. According to some research, mucin hypersecretion may also contribute to the formation of brown pigment stones. This may be explained in part by the findings that lipopolysaccharides derived from certain bacteria are effective stimulants of mucin secretion. Aspirin and nonsteroidal anti-inflammatory drugs inhibit gallbladder mucin secretion and prevent gallstone formation in animal models. Expanding our knowledge on mucin research may improve our understanding of the natural history of gallstone formation and enable the development of new treatment strategies.

Abstract
BACKGROUND Epidemiologic studies on the relationship between dietary fiber and gallstone disease are inconclusive, and the effects of different types of dietary fiber are not clear. METHODS We examined the association between long-term intake of dietary fiber as well as fiber from different sources and risk of cholecystectomy in a cohort of 69,778 women who were aged from 35 to 61 years in 1984 and had no history of gallstone disease. As part of the Nurses' Health Study, the women reported on questionnaires mailed to them every two years both their fiber intake and whether they had undergone cholecystectomy. RESULTS During 16 yr of follow-up, we documented 5,771 cases of cholecystectomy. After adjusting for age and other known or suspected risk factors in a multivariate model, compared with women in the lowest quintile of total dietary fiber intake, the relative risk of choleystectomy for those in the highest quintile was 0.87 (95% CI, 0.78-0.96, p for trend = 0.005). For a 5-g increase in total fiber intake, the multivariate relative risk was 0.94 (95% CI, 0.90-0.98). Insoluble fiber, taking soluble fiber into account in the multivariate model, was significantly associated with a reduced risk. The multivariate relative risk was 0.83 (95% CI, 0.73-0.94, p for trend = 0.009) for insoluble fiber, and was 1.01 (95% CI, 0.89-1.15, p for trend = 0.9) for soluble fiber, when extreme quintiles were compared. For a 5-g increase in intake, the relative risk was 0.90 (95% CI, 0.84-0.97) for insoluble fiber, and was 1.01 (95% CI, 0.83-1.23) for soluble fiber. CONCLUSIONS Our results suggest that increased long-term consumption of dietary fiber, particularly insoluble fiber, can reduce risk of cholecystectomy in women.

Abstract
OBJECT To determine if a 6-month regimen of prophylactic ursodeoxycholic acid is effective in the prevention of gallstones. SUMMARY BACKGROUND DATA Rapid weight loss after surgery for the treatment of morbid obesity is associated with a high incidence of gallstone formation. METHODS Patients with vertical banded gastroplasty (VBG) and adjustable gastric banding (AGB) were enrolled in this study. A single-center, randomized, double-blind, prospective trial evaluated 500 mg of ursodeoxycholic acid versus placebo, beginning within 3 days after surgery and continuing for 6 months or until gallstone development, for patients with morbid obesity. Transabdominal sonography or abdominal CT scan was obtained preoperatively at 3, 6, 12, and 24 months after surgery or until gallstone formation. RESULTS From March 1997 to April 2000, 262 patients were submitted to surgery. Seventy-seven patients refused to participate in the study; 43 patients with previous gallstone operation or verified gallstones preoperatively were excluded. Of 152 patients, 76 were randomized to placebo and 76 to 500 mg of ursodeoxycholic acid daily. Preoperative age, sex, weight, BMI, and postoperative weight loss were not significantly different between groups. Gallstone formation was significantly less (P = 0.0018, Fisher exact test) frequent with ursodeoxycholic acid than with placebo at 12 months, 3% versus 22%, and 8% versus 30% (P = 0.0022) at 24 months, cholecystectomy in 4.7% versus 12%, respectively (P < 0,02, Fisher exact test). CONCLUSION A daily dose of 500 mg of ursodeoxycholic acid for 6 months is effective prophylaxis for gallstone formation following gastric restrictive procedures.

Abstract
We have recently synthesized fatty acid bile acid conjugates (FABAC) that were able to reduce and retard cholesterol crystallization in model and human biles. When given orally, they prevented the formation of cholesterol crystals in the bile of hamsters. The aim of the present study was to determine whether the FABAC are cholesterol solubilizers, whether they can dissolve pre-existing crystals, whether they can prevent the formation of cholesterol gallstones, and to investigate the optimal type of bond between the fatty acid and bile acid. The presence of cholesterol crystals was determined by light microscopy, and the total crystal mass of precipitated crystals was measured by chemical means. Inbred (C57J/L) mice on a lithogenic diet were used to evaluate cholesterol crystal formation, dissolution, and gallstone formation in vivo. Arachidyl amido cholanoic acid (Aramchol) was the FABAC used in the present experiments. At equimolar amounts, the cholesterol-solubilizing capacity of Aramchol was higher than that of taurocholate and similar to that of phosphatidylcholine. The addition of Aramchol dissolved approximately 50% of pre-existing crystals in model bile solutions. The same phenomenon was demonstrated in human bile ex vivo, with a dose-response effect. All inbred mice developed cholesterol crystals in bile after 10-14 d on the lithogenic diet. Thereafter, supplementation of the diet with Aramchol progressively reduced the proportion of mice with crystals to 25% after 28 d. On the lithogenic diet, 100% of inbred mice developed cholesterol gallstones in the gallbladder by day 21. None of the mice whose diet was supplemented with 0.5 mg or 1.0 mg of Aramchol/d developed stones or crystals. FABAC are a new class of molecules that are cholesterol solubilizers and which are able to dissolve cholesterol crystals in bile. Upon oral administration, they dissolve pre-existing cholesterol crystals and prevent the formation of gallstones in gallstone-susceptible mice.

Abstract
BACKGROUND AND AIMS Octreotide treatment of acromegalic patients induces cholesterol gallstone formation, in part by impairing cholecystokinin release and gall-bladder contraction. However, there are few data on the effect of octreotide on biliary arachidonic acid-rich phospholipids or mucin glycoprotein, factors which also influence cholesterol gallstone formation. METHODS In acromegalic patients studied before and during 3 months of octreotide treatment, we measured mucin glycoprotein concentrations and the molecular species of phosphatidylcholine, and related the results to the cholesterol saturation and percentage of deoxycholic acid in gall-bladder bile. RESULTS The relative proportions of the major arachidonic acid-rich phosphatidylcholine species, PC 16:0-20:4 and PC 18:0-20:4, increased significantly during octreotide treatment. These changes were associated with a rise in the cholesterol saturation index and a non-significant twofold increase in mucin glycoprotein concentration. There were significant correlations between PC 16:0-20:4 and the cholesterol saturation index, percentage of vesicular cholesterol and percentage of deoxycholic acid in gall-bladder bile. CONCLUSIONS In acromegalic patients, octreotide increases the proportions of arachidonic acid-rich phospholipids, with associated rises in: (a) the cholesterol saturation index and percentage of vesicular cholesterol, and (b) the percentage of deoxycholic acid in gall-bladder bile-changes similar to those found in patients with cholesterol-rich gall-bladder stones.

Abstract
In order to analyze the factors associated with cholelithiasic disease, 1268 participants of a population sample were studied. On univariate analysis, 11 of the 23 variables included showed a statistically significant association (P < 0.05). Five of these variables, including obesity, triglyceride level, intake of hypolipidemic drugs, and a diet rich in cholesterol and saturated fats in women, and physical exercise in men, remained significantly associated after controlling for age. On multivariate analysis among women, a positive association was found with age (P < 0.001), obesity, and the use of hypolipidemic agents (P < 0.05) and a negative one with a diet rich in cholesterol and saturated fats (P < 0.05). Among men, the same analysis revealed there was a positive association with age (P < 0.001) and triglycerides (P < 0.05) and a negative one with physical exercise (P < 0.05). In conclusion, obesity and the use of hypolipidemic agents in women and triglycerides in men, were positively associated with cholelithiasic disease, independent of age, while negative associations included the intake of cholesterol and saturated fats in women and physical exercise in men.

Abstract
BACKGROUND/AIMS Extracorporeal shock wave lithotripsy (ESWL) with adjuvant bile salt dissolution therapy may be successful in selected gallstone patients, but the considerable risk of recurrence is a major drawback. Apolipoprotein E4 genotype and impaired gallbladder motility have been identified as major risk factors for recurrence during short-term follow up. We have now examined their relevance during long-term follow up. METHODS Eighty-four cholesterol gallstone patients (55 solitary and 29 multiple (two to ten) stones) were followed prospectively up to 10 years after complete stone disappearance. Various potential risk factors for recurrence were evaluated. RESULTS Gallstone recurrence was found in up to 80% of patients at 10 years follow-up. Absence of the apolipoprotein epsilon4 allele, initial solitary stones, good gallbladder emptying (i.e. minimal postprandial volume < or = 6 ml) and 2-year postdissolution ursodeoxycholic acid prophylaxis (in ten patients) all delayed but did not prevent recurrence. In contrast, regular use of non-steroidal anti-inflammatory drugs (NSAIDs) was identified as an independent protective factor, with greatly decreased recurrence (at 10 years: 58 vs 93% in non-NSAID users, P = 0.03). CONCLUSIONS Non-apolipoprotein E4 genotype, presence of solitary stones and good gallbladder emptying delay rather than prevent recurrence after initially successful ESWL. Regular use of NSAIDs may prevent recurrence.

Abstract
Nonsteroidal antiinflammatory drugs, inhibitors of prostaglandin synthesis, have different effects on gallbladder contractility in normal and diseased human gallbladders in vivo. We investigated this differential effect by comparing the effects of prostaglandins PGE2 and PGF2alpha, the thromboxane A2 mimetic U46619, and PGI2 on in vitro contractility in gallstone-free and gallstone-containing human gallbladders. Isometric tension was measured in gallbladder muscle strips mounted in organ baths. EC50 was calculated for each agonist. The rank order of potency in gallstone-free gallbladders was PGE2 > CCK > U46619 > PGF2alpha and in gallstone-containing gallbladders was U46619 > PGE2 > CCK > PGF2alpha. PGI2 produced contraction of gallstone-free gallbladder and relaxation of gallstone-containing gallbladder in the basal state. Further, PGI2 produced no relaxation in gallstone-free muscle strips precontracted with CCK, but significant relaxation in CCK precontracted gallstone-containing strips. PGE2, PGF2alpha, and U46619 are potent contractors of gallstone-free and gallstone-containing gallbladders, whereas PGI2 relaxes only gallstone-containing gallbladders. Since gallbladders containing cholesterol-supersaturated bile produce increased PGI2, this PGI2-induced relaxation may be a determinant of the impaired gallbladder motility of gallstone disease.

Abstract
BACKGROUND It has been suggested that gallstone disease is now commoner, and that this might explain an increase in cholecystectomy rates, though conclusive evidence has been lacking. METHODS All the non-forensic necropsy results for Dundee 1953-98 were examined to assess the prevalence of gallstone disease. The NHS Scotland annual cholecystectomy figures were extracted from their earliest availability in 1961 up to the present. The subgroup of patients from Dundee was analysed separately, as were laparoscopic procedures, which were recorded from 1991. RESULTS Gallstone disease was much commoner in 1974-98 than in 1953-73. Increasing age was the main determinant of gallstone disease. Though gallstone disease was commoner in women than men aged 40-89, there was no sex difference under 40 or over 90 years. Cholecystectomy became much commoner in the 1960s when frequency of gallstone disease did not change. It increased further in the 1970s, peaking in 1977-8. There was a gradual fall in rates in the 1980s when gallstone prevalence remained high. There was a further moderate rise in the 1990s after the wide introduction of laparoscopic cholecystectomy. Cholecystectomy is now much commoner in young women and this change started in the 1960s. By contrast, cholecystectomy in men has become more prevalent in the older age group. CONCLUSIONS Gallstones were definitely more common in both sexes at all ages over 40 in the last 25 years. Changes in the cholecystectomy rates are only partly explained by changes in gallstone prevalence, and are more determined by surgical practice.

Abstract
OBJECTIVE Results of previous studies on diet and gallbladder disease (GBD), defined as having gallstones or having had surgery for gallstones, have been inconsistent. This research examined patterns of food intake in Mexican Americans and their associations with GBD. DESIGN Cross-sectional. SUBJECTS The study population included 4641 Mexican Americans aged 20-74 years who participated in the 1988-94 third National Health and Nutrition Examination Survey (NHANES III). GBD was diagnosed by ultrasound. Food intake patterns were identified by principal components analysis based on food frequency questionnaire responses. Component scores representing the level of intake of each pattern were categorized into quartiles, and prevalence odds ratios (POR) were estimated relative to the lowest quartile along with 95% confidence intervals (CI). RESULTS There were four distinct patterns in women (vegetable, high calorie, traditional, fruit) and three in men (vegetable, high calorie, traditional). After age adjustment, none were associated with GBD in women. However, men in the third (POR = 0.42, 95%CI 0.21-0.85) and fourth (POR = 0.53, 95%CI 0.28-1.01) quartiles of the traditional intake pattern were half as likely to have GBD as those in the lowest quartile. CONCLUSIONS These findings add to a growing literature suggesting dietary intake patterns can provide potentially useful and relevant information on diet-disease associations. Nevertheless, methods to do so require further development and validation.

Abstract
Recent epidemiological studies have suggested that hyperinsulinaemia may be a central factor in the pathogenesis of cholesterol gallstones, explaining a probable link with physical inactivity as well as abdominal adiposity. There is also increasing evidence for the hypothesis that enrichment of bile with DCA. 'the colonic bile acid', leads to enrichment of bile with cholesterol. Biliary DCA can be raised and lowered by slowing down and speeding up colonic transit, respectively. Slow transit is characteristic of non-obese British women with gallstones and of non-obese peasants in a gallstone-prone mountain community. High biliary DCA predicts recurrence of gallstones and so does laxative usage, a pointer to constipation and therefore to slow transit. In some studies, at least, a high fibre intake is protective against gallstones. Much else besides fibre influences colonic function. Future studies of gallstone aetiology should include measurements of colonic function. Measures that speed up colonic transit should be tested for their ability to prevent gallstone formation in high-risk individuals.

Abstract
OBJECTIVE Dietary intake has long been looked upon as a potentially modifiable risk factor for gallbladder disease (GBD), here defined as either having gallstones or having had surgery for gallstones. This paper reviews the epidemiological evidence for an association between dietary intake and GBD, focusing on six dietary factors that have received the most attention in studies in this area: energy intake, fatty acids, cholesterol, carbohydrates and fibre, calcium and alcohol. The objectives of this review are to evaluate the potential usefulness of altering the diet to prevent GBD and to consider future research in this area. DESIGN We reviewed all English-language epidemiological studies on diet and cholelithiasis that were cross-sectional, cohort or case-control in design and that were indexed in the Medline database from 1966 to October 1997. RESULTS A positive association was suggested with simple sugars and inverse associations with dietary fibre and alcohol. No convincing evidence was found for a role for energy intake or intake of fat or cholesterol. Variable means of ascertaining cases and inaccurate measurement of dietary intake may contribute to variation in results across studies. CONCLUSIONS Some specific components of the diet that may affect GBD include simple sugars, fibre and alcohol, but whether risk for GBD can be reduced by altering intake of a specific dietary factor has not been established. Although no specific dietary recommendations can be made to reduce risk of GBD per se, a 'healthy' diet aimed at reducing risk of other diseases might be expected to reduce risk for GBD as well.

Abstract
Since there are now several ways to treat symptomatic gallstone disease, one is able to select treatment on the basis of the patient's comfort, the practicability, effectiveness, and side effects of the technique, and the relative costs. In order to assess the present status of contact dissolution with methyl tert-butyl ether with regard to these aspects, the present enquiry reports the data of 21 European hospitals. Eight hundred three patients were selected for contact litholysis of cholesterol gallbladder stones using methyl tert-butyl ether. Percutaneous transhepatic puncture of the gallbladder was performed under x-ray or ultrasound guidance. Dissolution rate, side effects, and treatment times of 268 patients from one single center were compared to those of 535 patients from the other 20 centers. Two hundred sixty-four patients were followed for five years to assess stone recurrence. Physicians were asked how they assessed the expenditure of the method, the discomfort to the patients, and the staffing situation. Patients were asked to indicate their acceptance on an analog scale. Puncture was successful in 761 (94.8%) patients. Prophylactic administration of antibiotics was not necessary. Stones were dissolved in 724 (95.1%) patients. In 315 (43.5%) sludge remained in the gallbladder. The most severe complication was bile leakage, which led 12 (1.6%) patients to have elective cholecystectomy. Toxic injuries due to the ether were not reported. Method-related lethality amounted to 0%, 30-day-lethality to 0.4%. Stone recurrence rate was about 40% in solitary stones and about 70% in multiple stones over five years. Patients with multiple stones developed recurrent stones almost twice as often as those with solitary stones. The probability of stone recurrence in patients with sludge in the gallbladder after catheter removal was not statistically significantly different from those without sludge. Seventy to 90% of the centers found the puncture to be simple and not distressing for patients and the relation between expenditure and therapeutic success to be acceptable. The acceptance of contact litholysis by the patients was excellent. Contact litholysis when applied by an experienced team provides real advantages in the treatment of gallstone disease. The method is technically simple, well accepted by the patients, and can be easily applied in community hospitals. Contact litholysis may be of particular value in patients who are not suitable for anesthesia or surgery.

Abstract
Topical dissolution of cholesterol gallbladder stones using methyl tert-butyl ether (MTBE) is useful in symptomatic patients judged too ill for surgery. Previous studies showed that ethyl propionate (EP), a C5 ester, dissolves cholesterol gallstones rapidly in vitro, but differs from MTBE in being eliminated so rapidly by the liver that blood levels remain undetectable. Our aim was to test EP as a topical dissolution agent for cholesterol gallbladder stones. Five high-risk patients underwent topical dissolution of gallbladder stones by EP. In three patients, the solvent was instilled via a cholecystostomy tube placed previously to treat acute cholecystitis; in two patients, a percutaneous transhepatic catheter was placed in the gallbladder electively. Gallstone dissolution was assessed by chromatography, by gravimetry, and by catheter cholecystography. Total dissolution of gallstones was obtained in four patients after 6-10 hr of lavage; in the fifth patient, partial gallstone dissolution facilitated basketing of the stones. In two patients, cholesterol dissolution was measured and averaged 30 mg/min. Side effects were limited to one episode of transient hypotension and pain at the infusion site; no patient developed somnolence or nausea. Gallstone elimination was associated with relief of symptoms. EP is an acceptable alternative to MTBE for topical dissolution of cholesterol gallbladder stones in high-risk patients. The lower volatility and rapid hepatic extraction of EP suggest that it may be preferable to MTBE in this investigational procedure.

Abstract
Rapid and safe gallbladder clearance from residual, post-MTBE stone debris is believed to be absolutely necessary to reduce stone recurrence after contact litholysis. Because the clearing effect of prokinetic agents is considered an uncertain postdissolution trial, we investigated by in vitro experiments whether and to what extent debris from various cholesterol and "mixed stones" could be removed by direct (topical) chemolysis. Debris from radiolucent cholesterol stones could be dissolved very easily, using the aqueous solvent S-01, composed of EDTA-2Na (1-2%), lauryl sulfobetaine-12 (0.1 M), and 0.1 M sodium carbonate/boric acid buffer, pH 9,5. Its dissolution capacity (DC) was 8.06 +/- 2.3 mg debris/ml and its dissolution efficacy (DE) was 16.2 +/- 4.6 mg debris/ml/hr. Debris from mixed, slightly to moderately calcified stones needed another treatment with S-05, composed of sodium citrate (0.25 M), lauryl sulfobetaine-12 (0.01 M), and citric acid. The initial pH was 5.2. The DC of S-05 ranged from 1.61 +/- 1.1 (debris enriched with Ca-phosphate) to 3.94 +/- 1.3 mg/ml (debris enriched with Ca-carbonate). Stones which did not respond immediately to MTBE because of a thin rim of inorganic or/and organic Ca salts could be made ready for MTBE litholysis by pretreatment with S-01 or S-05 or with a combination of both solvents. Debris containing large portions of biliary mucus could be dissolved most effectively by successive application of S-01 and S-06 (2 M urea).

Abstract
BACKGROUND/AIMS Following non-surgical treatment, cholesterol gallstones recur in a high proportion of patients, and recurrence cannot be predicted nor effectively prevented. Our aim was to test prospectively the viability and the efficacy of repeated bile acid therapy, in which recurrent stones are diagnosed at an early stage by regular ultrasound monitoring and promptly retreated, as a strategy for the management of these patients in clinical practice. METHODS One hundred and seventy-two consecutive patients were recruited upon achieving complete gallstone dissolution using non-surgical therapy (bile acids or lithotripsy plus bile acids), and followed up at 6-monthly intervals by ultrasound scan. Gallstone recurrence was promptly treated by a combination of ursodeoxycholic acid plus chenodeoxycholic acid (5 mg/kg per day each) for a period of 2 years, or less if complete redissolution was achieved. Median follow-up period was 34 months (range 6-70). RESULTS Forty-five patients had gallstone recurrence; of these, 39 underwent one or more repeated courses of bile acid therapy (follow-up data available in 27). Gallstone recurrence rate was 15% at 1 year and 47% at 5 years. Average annual redissolution rate of recurrent gallstones (intention to treat) was 41%. The proportion of gallstone-free patients in the whole population was 88%, 84%, 77%, 78%, 75% at 1-5 years, respectively, and rose to > 90% at 3 years onwards in patients with single primary stones. CONCLUSIONS We conclude that repeated bile acid therapy maintains the majority of patients gallstone free, and is therefore an effective long-term management strategy, especially in patients with primary single gallstones.

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
Secretion of gallbladder mucin is an important step in gallstone pathogenesis. Previous studies have demonstrated that aspirin and other nonsteroidal antiinflammatory drugs (NSAIDs) can both inhibit gallbladder mucin secretion and prevent gallstone formation in animal models of cholesterol gallstone disease. The present study was performed to determine if chronic NSAID use was associated with a reduction in the mucin content or affected the lipid components of human gallbladder bile. Four groups of patients were identified retrospectively from a cohort of 230 morbidly obese patients who underwent gastric bypass surgery. The index group consisted of 18 patients who were found to have gallstones at gastric bypass surgery and had a history of chronic NSAID use. Three other patient groups were identified from the cohort by matching this index population for sex, race, and age according to the following criteria: (1) patients with gallstones who had not utilized NSAIDs, (2) patients without gallstones but with chronic NSAID use, and (3) patients without gallstones and without a history of NSAID use. Gallbladder bile was obtained from all patients by direct aspiration from the gallbladder at the time of surgery. Patients with gallstones had a significantly (P < 0.02) greater concentration of gallbladder mucin in their gallbladder bile compared to patients without gallstones (0.897 +/- 0.226 vs 0.173 +/- 0.039 mg/ml). Among gallstone patients, gallbladder mucin was reduced in those patients with a history of chronic NSAID use (1.18 +/- 0.43 vs 0.74 +/- 0.19 mg/ml).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We report the recurrence rate of gallstone within 5 years after successful lithotripsy. One hundred and fifty consecutive patients (solitary stones, 102 patients; multiple stones, 48 patients) were followed up for a median of 42 months (range 6-72) after stone clearance and cessation of bile acid therapy. No patient received any therapy to prevent recurrence. Thirty-seven patients developed recurrent gallstones. Probabilities of recurrence were (mean +/- SD) 6.6% +/- 2%, 15.7% +/- 3%, 22.8% +/- 3.6%, 29.7% +/- 4.5%, 32.2% +/- 5% at 1, 2, 3, 4 and 5 years, respectively. The recurrence rate was lower in patients who had solitary stones than in patients with multiple stones (26.1% versus 47% at 5 years, respectively; p<0.009 - log rank test). Only five patients developed recurrent symptoms or stone complication (14%). We conclude that the recurrence rate after successful lithotripsy is lower than expected from dissolution studies, due to a low recurrence rate in patients who had solitary stones.

Abstract
To determine the rate and characteristics of gallstone recurrence after direct contact dissolution with methyl tert-butyl ether, 60 consecutive patients were followed for up to 4.5 years (median 2.2 years) after complete disappearance of all stone residues and debris and cessation of adjuvant bile acid therapy. Initial gallstones had been multiple in all but four patients. Twenty-eight of the 60 patients developed recurrent gallstones. The cumulative risk of gallstone recurrence (actuarial analysis) was 23 +/- 6%, 34 +/- 7%, 55 +/- 8%, and 70 +/- 9% at one, two, three, and four years, respectively. The recurrent stones were usually multiple and small (6 +/- 4 mm). Gallstone recurrence was associated with recurrent biliary pain in two patients, one of whom developed acute cholecystitis. Recurrent stones were cleared completely by bile acid medication with or without shock-wave lithotripsy in 61 +/- 15% of patients at one year (actuarial analysis). In conclusion, gallstone recurrence after successful contact dissolution of multiple stones with methyl tert-butyl ether has to be expected in a high percentage of patients. Most patients, however, remain free of biliary pain during long-term follow-up.

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.
