[Cholelithiasis and cancer: a study using precursor changes in a population with low incidence of cholelithiasis].

In order to assess the role of cholelithiasis in the pathogenesis of gallbladder carcinoma in a low-risk population for cholelithiasis and gallbladder cancer, we have studied the relationship between cholelithiasis and cancer. Our findings suggest that, both the relationship between cancer and cholelithiasis, and the frequency of precursors lesions, are very similar to those obtained in surveys carried out in high-risk populations for both conditions. Our findings bear out our hypothesis that cholelithiasis plays a main role in the pathogenesis of gallbladder carcinoma.

A study of cholelithiasis during pregnancy and its relationship with age, parity, menarche, breast-feeding, dysmenorrhea, oral contraception and a maternal history of cholelithiasis.

We prospectively studied 512 consecutive women attending the antenatal clinic of the Rotunda Hospital of Dublin, Ireland, to assess the prevalence of gallstones among them and to describe the characteristics of those women found to be gallstone-positive (group 1), compared with the negative-control population (group 2). Real-time ultrasound scanning of the pelvic area was extended to the upper part of the abdomen. Cholelithiasis was detected in 23 patients. No substantial difference was found in parity of group 1 as compared with group 2. Also, early pregnancies, age at menarche and oral contraception did not have any significant difference between the two groups. However, we recorded a significantly higher prevalence of cholelithiasis in older women and in patients with dysmenorrhea. A positive trend was found in patients who had a history of previous breast-feeding and in women with a positive maternal history of symptomatic gallstones.

A dietary survey to determine the relationship between diet and cholelithiasis.

A dietary survey was conducted to compare the dietary intakes of people with and without cholelithiasis (gallstones). A 48-hr recall method was used to collect dietary data from 91 cholelithiasis subjects (15 males and 76 females) and 86 control subjects (13 males and 73 females). Although the female cholelithiasis subjects were more overweight than the control subjects, they consumed less energy per day. It was observed that the female cholelithiasis group consumed less protein, fat, carbohydrate, and crude fiber than the female control group. Nutrient intakes per 1000 cal were similar for the female cholelithiasis and control groups. The total weekly intake of crude fiber and the intake of crude fiber specifically from bread and bakery products was significantly less for the female cholelithiasis group than for the female control group. This may indicate that it is a component of whole wheat flour that is low in the diet of subjects with gallstones. The results of this study suggest a possible relationship between cholelithiasis and a low intake of energy, protein, fat or crude fiber, but more than one of these nutrients could be involved. It is evident that further work is needed to study the relationship between diet and gallstone formation.

[Cholelithiasis after total gastrectomy for gastric cancer].

After gastric resection for peptic ulcer and total gastrectomy for Zollinger-Ellison syndrome, there is an increased prevalence of cholelithiasis. In order to assess whether this increased prevalence also exists after total gastrectomy for cancer, we evaluated the rate of cholelithiasis (echographic diagnosis) both before and after this operation. Between 1980 and 1990, 89 patients underwent total gastrectomy for cancer in the Surgical Department of our Institute. The pre-operative prevalence of gallstones was 5% in the males and 13.8% in the females. Seventy-four of the eighty-nine patients (83%) were examined post-operatively (7 patients with pre-operative cholelithiasis, 3 who died during the post-operative stay and 5 lost to follow-up were excluded from the study). The median post-operative follow-up was 24 months (range 3-115 months). The post-operative prevalence of cholelithiasis in the 74 patients was 39.6% in the males and 19% in the females. We also calculated the expected frequency of gallstones in both the pre- and post-operative groups from prevalence data in the population of the city where our Institute is based (taken from an echographic survey). We then compared the observed frequency of cholelithiasis with the expected frequency and we found that the difference in pre-operative frequencies, both in the males and females, was not statistically significant (p > 0.05). The same was true of the post-operative frequencies in the females (p = 0.48), but in the males there was a statistically significant difference between the observed frequency of cholelithiasis and that expected after total gastrectomy (p < 0.0001).(ABSTRACT TRUNCATED AT 250 WORDS)

[Incidence of cholelithiasis after its experimental induction by various methods].

The incidence rate of cholelithiasis was studied in varying methods of lithogenic stimulation: a diet enriched with cholesterol and chenodesoxycholic acid, induction of acute aseptic inflammation of the gallbladder by thermal damage, and the use of ++anti-gallbladder sera. The results of the study have shown almost similar (44-52%) reproducibility of cholelithiasis in guinea pigs, the development of pigment concrements was recorded in the absolute majority of cases. Correlation of the cholelithiasis incidence rate with inflammatory disorders in the gallbladder has evidenced the importance of the immunoallergic component in the determination of acute cholelithiasis and cholelithiasis, where cholelithiasis shows its secondary character.

Cholelithiasis in Jamaican patients with homozygous sickle cell disease.

The prevalence of cholelithiasis in Jamaican adults with SS disease was studied by plain abdominal radiograph in 206 patients and by oral cholecystogram in 126 (61%) of these patients. Gallstones were found in 57 (28%) of patients, were more common in females than males, and increased with age and hemolytic rate. The majority of gallstones were visible on the plain abdominal radiograph, only 17% of patients with gallstones having only radiolucent stones. Nonfunctioning oral cholecystograms were common (10%) in agreement with observations by previous workers. Gallstones were noted in the common bile duct in 2 patients. In general there was no clear relationship between the presence of cholelithiasis and clinical symptomatology. Complications, such as pancreatitis and malignant change in the gall bladder, recognized to be associated with cholelithiasis in the general population, have not been clearly related to cholelithiasis in SS disease. More information is needed before a logical policy can be evolved for surgical intervention in cholelithiasis in SS disease.

Cholelithiasis in infants with Down syndrome. Three cases and literature review.

Only four cases of cholelithiasis have been reported in patients with Down syndrome and none in Down syndrome infants. The cases of three Down syndrome infants (all males) with cholelithiasis are reported. Each exhibited different fetal complications, and in each, Down syndrome was diagnosed at birth. Gallstones apparently were congenital (a rarity) in one infant, since they were detected on the first day of life. Cholelithiasis was an incidental finding in another of the infants when, at 12 weeks old, he had renal ultrasonography because of a urinary tract infection. The third infant was 4 months old when sonographic studies revealed a gallstone. Despite the confirmation of cholelithiasis in all three infants, none has since had any signs or symptoms that suggest the need for intervention. Cholelithiasis is probably more common in Down syndrome infants than has been supposed, but whether Down syndrome infants with gastrointestinal (GI) malformations are more likely to have gallstones than are children with similar GI malformations but with normal karyotypes is unknown.

[Incidence of cholelithiasis in patients with cancer of the colon and adenomatous polyp].

Recent international publications remark the association about carcinoma of the colon and cholelithiasis. These two entities with similar geographical distribution can be seen frequently in the modern western societies, being the cause as aetiological factors the low content in dietetics fiber. Different studies about the carcinoma of the colon and cholelithiasis pathogenesis had lead the possibility that the abnormal degradation of bile acids for the colonic bacterias, could be responsible of each one of these illness. The exposition of colonic mucosa to products of degradation of bile acids, specially secondary bile acids, may play a role in the etiopathogenic of colon carcinoma. It was analysed 135 patients with colon carcinoma or adenomatosis polyps, 42 with cholelithiasis or cholecystectomized for the same cause (31.1%), although in the control group, only 2(5%) had cholelithiasis. The female predominated the group of colon carcinoma and cholelithiasis, as well as cholecystectomized for that cause. The most frequent associated pathology was the diverticulosis.

[The management procedure for patients with cholelithiasis and the results of rehabilitative treatment after cholecystectomy based on polyclinic observations].

Based on an analysis of the dynamic ultrasonic, biochemical and hormonal data on 550 patients operated on for cholelithiasis and comparison of preoperative and pathomorphological diagnoses, indications for surgical treatment of cholelithiasis patients in the stage of so-called "lithocarriership" were developed and a group at risk for cancer was identified as well. A comprehensive analysis of the clinical and instrumental data on 185 patients operated on for cholelithiasis, made in the long-term periods (from 1 to 3 years) after cholecystectomy indicates the efficacy of differentiated rehabilitation treatment, including elderly subjects and the necessity of early surgical treatment of cholelithiasis before there may develop irreversible alterations in the choledochus, liver and pancreas and in the gallbladder itself. Comparison of the dynamic ultrasonic data, liver and pancreas functions and factors such as sex, age, obesity and physical exercise makes it possible to predict the course of cholelithiasis to a certain degree of probability at the asymptomatic stage and to specify the policy of managing such patients under ambulatory conditions.

Prevalence and management of cholelithiasis in heart transplant patients.

There is no accepted approach in the field of heart transplantation for the management of asymptomatic cholelithiasis. To help formulate a strategy, we retrospectively reviewed the records of the 159 patients who underwent heart transplantation at our institution from March 1984 to January 1990. Information on the biliary tract was available in 141 (88.7%) of these patients. Before transplantation, 18 (11.3%) had undergone cholecystectomy. Of the 141, 99 (70.2%) had undergone ultrasonographic examination of the biliary tree: 74 (74.8%) had no gallstones seen on ultrasonograms; 8 (8.1%) had sludge; 16 (16.2%) had gallstones; and 1 had a probable polyp. Further information on the biliary tree by ultrasonography became available after transplantation in 24 of 42 patients who did not undergo ultrasonographic examination before transplant. After transplant, gallstones were found by means of ultrasonography or at autopsy in 13 more patients. Seven (4.4%) patients underwent cholecystectomy after transplant because of symptomatic cholelithiasis. Only one of these patients belonged to the group known to have gallstones before transplant. For the entire group, the prevalence of cholelithiasis was 29.6%. Multivariate analysis demonstrated that gallstones were significantly more common in older patients. We conclude that the prevalence of cholelithiasis in the heart transplant population is high but that only a minority of patients with asymptomatic gallstones will become symptomatic after heart transplantation. When they do, cholecystectomy may be safely performed. Prophylactic cholecystectomy and screening ultrasonography are not indicated in patients with asymptomatic cholelithiasis.

Cholelithiasis and biliary tract disease in sickle-cell disease in Nigerians.

The incidence of biliary tract disease was investigated by oral cholecystography and/or intravenous cholangiography in 77 unselected Nigerians with homozygous sickle-cell disease (SCD). They included 32 males and 45 females with ages ranging from 8 to 31 years. The prevalence of cholelithiasis was 9% with equal sex incidence. The stones were always multiple and 71.4% of them were radio opaque. Visualization and contractility of all gall bladders examined were normal. The only patient with symptoms and signs which suggested biliary tract disease had no radiographic evidence of cholelithiasis and it was impossible to predict the presence of cholelithiasis from the incidence of abdominal crises in the patients. The prevalence of cholelithiasis is significantly less than that reported in American patients with SCD (35%) and different dietary habits are probably responsible for this.

Causal effects of cholelithiasis on hepatopancreatobiliary diseases: a multi-cohort Mendelian randomization study.

BACKGROUND: Cholelithiasis is commonly associated with multiple hepatopancreatobiliary diseases, yet whether these relationships reflect causal mechanisms or shared risk factors remains unclear. METHODS: We performed a phenome-oriented two-sample Mendelian randomization (MR) analysis to evaluate the causal impact of genetic liability to cholelithiasis across hepatopancreatobiliary outcomes. Independent genome-wide significant variants were selected as instrumental variables. Primary analyses used inverse variance weighting, complemented by sensitivity analyses, reverse MR, and multivariable MR adjusting for body mass index (BMI). RESULTS: Genetic predisposition to cholelithiasis was associated with increased risk of acute pancreatitis and extrahepatic cholangiocarcinoma (eCCA), with consistent directionality across datasets.The association with acute pancreatitis was interpreted as a positive control, whereas the null association with alcohol-induced acute pancreatitis served as a negative control. No causal association was observed for portal vein thrombosis. Sensitivity analyses, including MR-PRESSO and MR Steiger filtering, supported the robustness and directionality of the causal estimates. Reverse MR analyses showed no consistent evidence supporting reverse causality. Multivariable MR indicated that observed effects were not fully explained by BMI-related pathways. CONCLUSION: These findings suggest that cholelithiasis susceptibility may contribute to the broader hepatopancreatobiliary disease network, extending its clinical relevance beyond a localized biliary disorder.

Atherosclerosis in relation to cholelithiasis and cholesterolosis.

The frequency of cholelithiasis and cholesterolosis was remarkably similar in Prague and Malmö subjects. When the possible effects of associated hypertension or diabetes mellitus were taken into account, subjects with cholelithiasis showed the same extent of raised and calcified lesions of the coronary arteries, the same prevalence of large myocardial scars, and the same distribution of heart weight as subjects without cholelithiasis. In general, they showed rather fewer raised and calcified lesions of the aorta, less coronary stenosis, and fewer fresh myocardial infarctions than subjects without cholelithiasis. Subjects with cholesterolosis were similar to those without this condition in respect of raised lesions of the aorta and coronary arteries. Men with cholesterolosis had slightly more aortic calcification and slightly less coronary calcification. Women with cholesterolosis had slightly less coronary stenosis than those without cholesterolosis. There was a slight tendency for those with cholesterolosis to show an increased frequency of fresh myocardial infarction and large myocardial scars and to have a higher heart weight.

Cholelithiasis in infants receiving furosemide: a prospective study of the incidence and one-year follow-up.

Cholelithiasis has been reported to occur rarely in infants. To determine the incidence of cholelithiasis in infants receiving furosemide, we prospectively performed ultrasonograms on 86 patients. We studied 42 patients receiving furosemide (subjects) and 44 patients not receiving furosemide (controls). There was a significantly higher incidence of gallstones in subjects (21%) than in controls (2%) (P less than .05). When followed over 1 year, the gallstones did not resolve. There were no significant differences in the dosage of furosemide, gestational age, placement of umbilical venous catheters, or amount of total parenteral nutrition (TPN) between subjects with and without gallstones. However, subjects received more days of TPN (16.7 +/- 15.1) than controls (8.4 +/- 13.2) (P less than .05). These data show that the incidence of cholelithiasis is higher than previously suspected in infants receiving furosemide. Thus, furosemide, either independently or in conjunction with the use of TPN, predisposes infants to the development of cholelithiasis.
