Gallbladder disease: appearance of associated transient increased attenuation in the liver at biphasic, contrast-enhanced dynamic CT.

PURPOSE: To evaluate the frequency, location, and appearance of transient increased attenuation in the liver during arterial-phase helical or incremental computed tomography (CT) in patients with gallbladder disease without hepatic extension. MATERIALS AND METHODS: Findings in dynamic CT examinations in 31 patients with surgically proved gallbladder disease not extending into the liver and in 31 control patients without gallbladder disease were retrospectively reviewed and correlated with findings in other imaging examinations. RESULTS: Areas of transient increased hepatic attenuation (n = 27) were identified in 22 of 31 patients with gallbladder disease and in only one of 31 control patients. The difference in these findings was statistically significant (P < .001). In the 27 areas of transient increased hepatic attenuation, these findings were categorized as curvilinear or nodular attenuation adjacent to the gallbladder fossa in 13 (48%), segmental or subsegmental attenuation in segment IV and/or V in seven (26%), lobar attenuation in the left lobe (segments II-IV) in four (15%), and nodular attenuation seen as an early enhancing "pseudolesion" in segment IV in three (11%). Hepatic angiography performed in 10 of the 22 patients showed early depiction of the dilated cystic vein (n = 8) and direct communication with the portal branches (n = 2). CONCLUSION: Transient increased attenuation in the liver had a variable appearance at dynamic arterial-phase CT in most patients with gallbladder disease. This attenuation was most likely due to increased blood flow from the hepatobiliary system.

The radiological diagnosis of gallbladder disease. An imaging symposium.

Changes in the radiological diagnosis of gallbladder disease are occurring at a remarkable rate. In this symposium, several recognized authorities place the various diagnostic modalities and their interrelation in modern perspective. The present and future roles of oral cholecystography and intravenous cholangiography, the radiological diagnosis of chronic acalculous cholecystitis, and the use of ultrasonography and cholescintigraphy are analyzed.

The role of prostaglandins E and F in acalculous gallbladder disease.

Prostaglandins have been postulated to be involved in the formation of gallstones and the pain and inflammation of calculous gallbladder disease. This report evaluated prostaglandin E and F levels in patients with acalculous gallbladder disease. Control gallbladders were obtained from patients undergoing cholecystectomy during insertion of hepatic artery catheters for regional, hepatic chemotherapy. Patients without gallstones and with long-standing post-prandial biliary colic with abnormal cholecystokinin administration underwent cholecystectomy for chronic acalculous cholecystitis. A third group of patients underwent cholecystectomy for acute acalculous cholecystitis. Gallbladder mucosa and muscle were separated, and prostaglandin E and F concentrations in mucosal and muscle or mucosa were identified in gallbladders from patients with chronic acalculous cholecystitis compared to gallbladders from patients without biliary tract symptoms. In gallbladders from patients with acute acalculous cholecystitis a seven-fold increase in PGE production by muscle tissue and mucosal cells was found. The more histologically inflamed gallbladders had higher mucosal and muscle prostaglandin E concentrations than were found in less inflamed gallbladders. Prostaglandin F levels were not significantly changed or were decreased, resulting in a significant increase in the ratio of PGE/PGF in acutely diseased gallbladders when compared to normal gallbladders. Prostaglandin E may be a manipulatable intermediary in the sequence of events that results in the development of acute acalculous cholecystitis.

Association between serum concentration of apolipoproteins A-I and B with gallbladder disease.

BACKGROUND: A total of 1,255 subjects attending a private health care facility in Mexico City were studied to evaluate the association of serum concentration of Apo A-I and Apo B with presence of gallbladder disease (gallstones or cholecystectomy). METHODS: A cross-sectional study was carried out. All participants provided data on sociodemographic status and previous diagnoses of type 2 diabetes, hypertension, cardiovascular events, alcohol consumption, and smoking habits. Women additionally reported their obstetric-gynecologic history. Weight and height were measured; liver and biliary tract ultrasound assessed gallbladder disease. Plasma levels of total cholesterol, triglycerides, high-density lipoproteins (HDL) cholesterol, and apolipoproteins A-I (Apo A-I) and B (Apo B) were determined after a 12-h fasting period. RESULTS: In multivariate models, Apo A-I > or = 120 mg/dL was positively associated with gallbladder disease with odds ratio (OR) = 1.64, 95% confidence interval (95% CI) = 1.03-2.62, whereas Apo B > or = 120 mg/dL showed an inverse association (OR = 0.71, 95% CI = 0.48-1.05). Ratio of Apo B/Apo A-I > or = 1 was inversely associated with risk of gallbladder disease (OR = 0.54, 95% CI = 0.37-0.80). All models were adjusted for age, gender, body mass index (BMI), previous diagnosis of type 2 diabetes, triglycerides, alcohol consumption, tobacco, and contraceptive use, as well as for total cholesterol in HDL-cholesterol and Apo A-I models. CONCLUSIONS: Our results suggested the relationship between serum concentration of apolipoproteins and gallbladder disease. These findings support the hypothesis of increased biliary catabolism of cholesterol in subjects with gallbladder disease characterized by lower Apo B and higher Apo A-I serum concentrations.

Increased risk of symptomatic gallbladder disease in adults with Down syndrome.

Previous reports have documented an increased prevalence of asymptomatic cholelithiasis among children with Down syndrome. Whether this predisposes adults with Down syndrome to symptomatic gallbladder disease has not been studied. A case control study compared the rate of symptomatic gallbladder disease in 28 index cases of adults with Down syndrome and that of sex-matched controls. The rate of gallbladder disease was 25% among the Down syndrome group, compared to 4.5% among the control group (P = 0.002). Patients with Down syndrome were also more likely to have a family medical history of gallbladder disease. Utilizing logistic regression analysis, the adjusted relative risk for gallbladder disease among individuals with Down syndrome was 3.52.

Oral contraceptive use and benign gallbladder disease; revisited.

An analysis is described of 482 women with benign gallbladder disease (surgically confirmed in 407) identified in the Oxford Family Planning Association contraceptive study. There was no significant overall association between oral contraceptive use and gallbladder disease (relative risk ever use to never use 1.1, 95% confidence interval 0.9 to 1.3). Likewise, duration of oral contraceptive use had no significant effect (relative risk 97 or more months use to never use 1.1, 95% confidence interval 0.8 to 1.5). There was no indication of any interaction between oral contraceptive use and body mass index or oral contraceptive use and age in the production of disease. It is concluded that it is unlikely that oral contraceptives are of either clinical or public health significance in relation to the occurrence of gallbladder disease.

Detection of occult gallbladder disease by duodenal drainage.

Examination of gallbladder bile in the sediment of duodenal drainage obtained after magnesium sulfate stimulation was used to evaluate the presence or absence of gallbladder disease in thirty-four patients with symptoms suggestive of cholecystitis and normal or equivocal oral cholecystography. Ten patients had positive tests and nine of these had cholecystectomy. All nine had pathologically confirmed cholecystitis and seven of nine had cholelithiasis. Three patients with negative test results had laparotomy and normal gallbladders. The remaining twenty-one patients with negative tests have been followed up to three years, and none have returned with evidence of biliary tract disease. The results of this study suggest that duodenal drainage (Meltzer-Lyon test) is a valuable adjunctive diagnostic study in patients with gallbladder disease symptoms in whom normal or equivocal oral cholecystograms are obtained.

An ultrasound survey of gallbladder disease among Mexican Americans in Starr County, Texas: frequencies and risk factors.

The Mexican-American population of south Texas has been shown previously to have elevated frequencies of gallbladder disease, based on medical history. In the present study, ultrasonography was employed to screen 1004 randomly selected individuals aged 15 to 74 years. Among women, the frequency of previous cholecystectomy was 10.0%; the frequency of stones on ultrasound was 12.2%. In men, the respective frequencies were 1.7% and 6.3%. Highest frequencies of gallbladder disease occurred among those aged 45 years or above: 40.2% and 19.2% among women and men, respectively. Non-insulin-dependent diabetes mellitus, obesity, and hypertension were also markedly elevated in this population. Overall, more than 40% of the population had either gallbladder disease, non-insulin-dependent diabetes, obesity, or hypertension. Among those older than 45 years, 70% had one or more of these chronic conditions. Examining the associations of gallbladder disease with other chronic diseases or measures of lipids, lipoproteins, and apolipoproteins demonstrates that factors predictive of or associated with cholecystectomy are different from those for gallstones by ultrasound. Diabetes and obesity show the strongest associations with cholecystectomy among women under 45 years (women with diabetes being 6.8 times as likely to have had a cholecystectomy than those without diabetes). Testing an extensive array of lipid-related measures resulted in no clear patterns, with the possible exception of alpha-lipoprotein and related measures. That the Mexican-American population is relatively young and experiencing extremely rapid growth indicates that the burden of chronic disease in general and gallbladder disease in particular will increase dramatically in the coming years.

Gastric emptying in patients with flatulent dyspepsia, with and without gallbladder disease.

It has been suggested that the symptoms of flatulent dyspepsia are caused by a functional disturbance of the upper gastrointestinal tract. The aim of this study was to investigate delayed gastric emptying as the basis of symptoms in patients with and without gallbladder disease and after cholecystectomy. There were 13 dyspeptic patients with gallbladder disease, 12 with normal gallbladders, and 13 post-cholecystectomy patients. Gastric emptying was measured by means of a 99mTc-labelled scrambled egg meal and external scintillation counter. The rate of emptying in the symptomatic groups was compared with that in 24 asymptomatic normal control subjects and 12 non-dyspeptic patients with gallbladder disease. Delayed gastric emptying tended to occur in patients with gallbladder disease with and without dyspepsia and was not specifically associated with symptoms.

Gallbladder wall thickening: patients without intrinsic gallbladder disease.

Retrospective analysis of 22 patients with increased gallbladder wall thickness (4--10 mm) in the absence of gallbladder disease revealed that 19 were hypoalbuminemic (albumin less than 3.6 g/dl). To test the hypothesis that hypoalbuminemia was a causal factor, gallbladder wall thickness was measured in 40 patients selected prospectively solely on the basis of hypoalbuminemia. This group was compared to 25 normal volunteers. Hypoalbuminemic patients had significantly thickened gallbladder walls compared to volunteers (p less than 10(-9)). This thickening was associated not only with hypoalbuminemia, but also with increased main portal vein diameter, which reflects portal venous blood pressure. Gallbladder wall thickening unrelated to intrinsic gallbladder disease seems to be influenced by the same parameters as ascites formation--plasma colloid oncotic pressure and portal venous pressure.

Gallbladder disease as a side effect of drugs influencing lipid metabolism. Experience in the Coronary Drug Project.

We analyzed data obtained during the Coronary Drug Project to discover the influence of the drugs used on the frequency of gallbladder disease. Of 2680 placebo-treated men who had had myocardial infarction, gallbladder disease developed in 69. Corresponding figures for those given 2.5 mg of estrogen, 5.0 mg of estrogen and 1.8 g of clofibrate per day were 46 of 1061, 47 of 1081 and 42 of 1051, respectively. Each treatment group differed from placebo by over twice the standard error of the difference, life-table analysis yielding P less than 0.05 for each drug-placebo comparison. Forty-five variables, including age, body weight, blood pressure, serum lipids and blood sugar, were evaluated as risk factors. Age significantly correlated with prevalence of known gallbladder disease at entry (r = 0.066, P less than 0.001). No variable yielded a strong and consistent correlation with the incidence of subsequent new gallbladder disease. Gallstone formation is a risk whenever clofibrate or estrogen is prescribed.

Oral contraceptives and the risk of gallbladder disease: a meta-analysis.

OBJECTIVES: This study was designed to assess the risk of gallbladder disease due to oral contraceptive use by conducting a thorough literature review. METHODS: Controlled epidemiologic studies published through March 1992 were systematically searched and evaluated. Of 25 studies (27 publications), 9 could stand the test of critical appraisal with respect to validity. Restriction to these studies was judged to circumvent publication bias at the same time. RESULTS: Oral contraceptive use is associated with a slightly and transiently increased rate of gallbladder disease. The results of six selected studies in which asymptomatic women were screened for gallstones were strikingly similar. Pooling of these results yielded an odds ratio, for ever vs never oral contraceptive use, of 1.36. A dose-effect relationship was indicated, suggesting that modern low-dose oral contraceptives are safer than older formulas, but an effect cannot be excluded. CONCLUSIONS: Considering the large efforts already devoted to this exposure-disease relationship, the probably weak effect, and the rapidly changing formulas of oral contraceptives, the authors suggest that the safety of new oral contraceptives be evaluated by studying bile saturation and biliary function rather than by waiting for gallbladder disease to develop.

Prospective study of clinical gallbladder disease and its association with obesity, physical activity, and other factors.

The association of anthropometric measurements, serum tests, and life-style factors with the risk of clinical gallbladder disease was investigated in a prospective study of 7831 American men of Japanese ancestry in Hawaii. After 152,831 person-years of observation, 471 incident cases of gallbladder disease were diagnosed by histology or radiology. There was an increase in risk of gallbladder disease with a progressive increase in body mass index, height, pack-years of cigarette smoking, and diastolic blood pressure. There was a decrease in risk with an increase in physical activity, after controlling for the effect of other variables. There was also an inverse association with total caloric intake that could be related to dietary restriction in obese subjects or to the limitations of the 24-hr diet history. Serum cholesterol levels and the intake of total fat were not related to clinical gallbladder disease in this cohort.

The negative cholecystogram in gallbladder disease.

Seventeen cases of radiologically negative gallbladder disease are presented. In all it was possible to explain the symptoms on the basis of the 'disappearing stone' hypothesis. It is suggested that cholecystectomy should be advised in such patients provided that the symptoms are sufficiently characteristic and sufficiently severe.

Endoscopic stenting of the gallbladder for symptomatic gallbladder disease in patients with end-stage liver disease awaiting orthotopic liver transplantation.

Cholecystectomy in patients with advanced cirrhosis is associated with excessive morbidity and mortality. Because open cholecystectomy in patients with Child's class C cirrhosis has a reported mortality rate as high as 83%, symptomatic gallbladder disease in patients awaiting orthotopic liver transplantation (OLT) poses a unique clinical problem. The goal of this study is to determine whether the treatment of symptomatic gallbladder disease with endoscopic stenting of the gallbladder effectively reduces biliary symptoms and complications or the need for cholecystectomy. Thirteen patients with symptomatic gallbladder disease with and without cholelithiasis and advanced cirrhosis who were candidates for OLT underwent placement of a biliary stent from the gallbladder to the duodenum at endoscopic retrograde cholangiography. In each patient, biliary symptoms and complications ceased after stent placement. Seven patients underwent successful OLT 1 to 24 months after the procedure. One patient subsequently became a noncandidate for OLT and died of diabetes complications 3 years after the procedure. Five others are awaiting OLT (6 to 28 months postprocedure). One patient had recurrent pericholecystic fluid collection requiring percutaneous drainage and antibiotic therapy 8 months after the procedure. No patient has had recurrent symptoms, and currently all patients are free of complications. None required surgical intervention of the gallbladder or biliary tree. We conclude that endoscopic stenting of the gallbladder is the preferred treatment for symptomatic gallbladder disease in patients with end-stage liver disease awaiting OLT. This approach is noninvasive, safe, and effective in preventing potential morbidity and mortality.

Sincalide in patients with parenteral nutrition-associated gallbladder disease.

OBJECTIVE: To review the role of sincalide in treating and preventing parenteral nutrition (PN)-associated gallbladder disease. DATA SOURCES: A MEDLINE (1996-March 2004) search was performed using the key terms cholecystokinin, sincalide, parenteral nutrition, cholelithiasis, cholestasis, and sludge. DATA SYNTHESIS: Five human studies investigated the safety and efficacy of sincalide in patients with PN-associated gallbladder disease. Sincalide at intravenous doses of 0.04 microg/kg 3 times daily increased bile flow and improved serum bilirubin levels. However, patients with advanced liver disease did not respond to sincalide therapy. Long-term follow-up data on sincalide effects on liver disease progression are not yet available. CONCLUSIONS: Sincalide improved the signs of cholestasis. However, its long-term effects in preventing and treating PN-associated gallbladder disease remain unknown and its routine use for this indication cannot be recommended at this time.

Gallbladder disease in hyperlipoproteinaemia.

The occurrence of gallbladder disease (G.B.D.) (cholelithiasis, cholecystitis, cholecystectomy) was examined in patients consecutively admitted beccause of hyperlipoproteinaemia types IIa and IV. Altogether 37 of the 52 patients with the type IIa pattern were women, whereas 56 of the 75 subjects with hyperlipoproteinaemia type IV were men. The overall incidence of G.B.D. in the group with the type IIa was 13 per cent in the males and 22 per cent in the females; the corresponding figures in type IV were 41 per cent and 68 per cent, respectively. The findings in the major age-group (40-59 years) were compared with those from three necropsy series covering subjects of the same age. The incidence of G.B.D. was then found to be normal in type IIa but abnormally high in type IV. Patients with and without G.B.D. did not differ with regard to body-weight or glucose tolerance.
