Association between Neutrophil-to-high-density lipoprotein-cholesterol ratio and gallstones: insights from the national health and nutrition examination survey (2017-2020).

BACKGROUND: Inflammatory responses and lipid metabolism make vital impacts on the development of gallstones. This study investigated the relationship between gallstone disease (GSD) and the neutrophil-to-high-density lipoprotein cholesterol ratio (NHR) in American patients with gallstones. METHODS: The data analyzed were sourced from the 2017-2020 National Health and Nutrition Examination Survey (NHANES) and comprised of participants with complete data on GSD and NHR. The relationship between NHR and GSD was evaluated with weighted multivariable logistic regression analysis. Additionally, subset analyses, interaction tests, smoothed curve fitting, and threshold effect analyses were conducted. RESULTS: Among the 7894 participants analyzed in this study, the prevalence of GSD was 10.98%, and the average NHR value was 3.41 ± 0.06. The fully adjusted multivariable logistic regression results demonstrated an obvious positive association between NHR and the likelihood of GSD (OR = 1.09, 95% CI: 1.01, 1.16; P = 0.0197). Consistency of this association was confirmed through subset analyses and interaction tests across various subgroups, including those categorized by smoking status and asthma. Furthermore, smoothed curve fitting and threshold effect analyses revealed a nonlinear relationship with a threshold of 2.86. CONCLUSIONS: NHR shows a positive relationship to an increased likelihood of GSD among Americans. It can act as an easy and cost-effective tool for the early detection and management of individuals at risk for GSD.

Impact of Imaging Techniques in the Assessment of Gallstone Pancreatitis.

From the category of biliary disease, gallstones registered an increase during the last years, approximately 6% of men and 9% of women being affected by the pathology in the United States only. In western countries between 10-20% of the adult population is suffering from cholelithiasis. Although increasing age is a major risk factor for their formation, late studies correlate gallstones appearance with an age decrease for the onset of symptoms. We therefore face a younger population manifesting pain and sometimes functional disability. In accordance with statistical analysis, the economic impact of gallstones in highly industrialized countries such as United States produces costs of up to 6.5 billion dollars annually. In this context, the appropriate timing for intervention becomes a factor of major interest. The present review uses 28 articles and specialized literature. Article selection was based on keywords and followed the effectiveness of imaging investigation such as ultrasound, CT and MRI for patients diagnosed with cholelithiasis. Since a direct comparison between the imaging investigation techniques is not concluding we have tried to establish the sensitivity and specificity offered by each imaging assessment. The comparative analysis revealed a p Kruskal-Wallis <0.001 for sensitivity and p Kruskal-Wallis=0.474 for specificity.

Gender-Affirming Hormone Therapy With Estrogen Causing Gallstone Associated Acute Pancreatitis.

Background/Objective: Although estrogen is one of the main agents used to treat transgender women, there are few reports of acute pancreatitis (AP) of this illness in this group. The objective of this report is to describe a transgender woman who developed AP in the setting of estrogen treatment and gallstone disease. Case Report: A 38-year-old transgender woman presented with severe abdominal pain and vomiting. Her medical history included gender dysphoria managed with gender-affirming hormone therapy comprising estradiol valerate, progesterone, and spironolactone. Initial management involved supportive care, antibiotic therapy, and endoscopic retrograde cholangiopancreatography with biliary stent placement. Imaging confirmed acute interstitial edematous pancreatitis without necrosis, guiding treatment decisions toward laparoscopic cholecystectomy. Pathological examination revealed multiple gallstones, affirming the diagnosis of AP secondary to choledocholithiasis, likely associated with estrogen use. Postprocedural recovery was uneventful, with eventual removal of the biliary stent and resolution of symptoms. Discussion: There are only 7 reported cases in literature on estrogen-induced AP in transgender individuals undergoing gender-affirming hormone therapy. Most of these were primarily linked to hypertriglyceridemia. Conclusion: High-dose estrogen therapy in transgender women can elevate the risk of AP through the development of gallstones, underscoring the importance of thorough patient evaluation and discussion of risks assessment prior to initiating hormone therapy.

Comparison of Triglyceride-Glucose Index between Patients with Gallstone and Healthy Individuals.

Background: Triglyceride-glucose index is a product of triglycerides and fasting plasma glucose (FPG) and is a new index of insulin resistance found to correlate with direct measurements. This study aimed to evaluate the relationship between gallstones and triglyceride-glucose index (TGI). Methods: A total of 210 patients were included in this retrospective study. Overall, 105 patients with gallstones were included in the patient group. Patients with diabetes mellitus, chronic diseases, malignant diseases, and patients using cholesterol-lowering drugs were excluded from the study. Healthy individuals (105 cases) were selected for the control group. TGI was calculated separately for each individual using the following formula: (TGI) = ln (fasting TG (mg/dL) × fasting glucose (mg/dL)/2). Results: Plasma triglyceride levels were significantly higher in patients with gallstones compared to the control group (P=0.001). Plasma HDL, LDL, and total cholesterol did not differ between the groups (P>0.05). Fasting blood glucose was significantly higher in patients with gallstones compared to the control group (P=0.001). The triglyceride glucose index was significantly higher in patients with gallstones compared to the control group (P<0.001). When the relationship between body mass index and TGI was analyzed, TGI was lower in patients with normal BMI compared to overweight or obese patients (P<0.001). Conclusion: Increased triglyceride/glucose index in patients with gallstones is an indicator of insulin resistance. It is instrumental in demonstrating the presence of insulin resistance in patients with gallstones and may be a useful guide in earlier detection, prevention, and treatment of insulin resistance.

Management of Acute Cholangitis and Choledocholithiasis.

Acute cholangitis is a life-threatening emergency, caused by blockage of bile, most commonly by a gallstone (choledocholithiasis). Stasis of bile leads to an infection in the biliary tree known as cholangitis. Cholangitis is graded into 3 categories according to severity of symptoms. The infections are polymicrobial and are predominantly gram-negative rods. Management consists of early initiation of antibiotics and prompt biliary decompression. The biliary tree can be drained by endoscopic retrograde cholangiopancreatography, percutaneous transhepatic cholangiography, rendezvous, or surgical means. Future directions will focus on improving quality of and access to minimally invasive means of clearing the biliary tree.

Laparoscope combined with ureteroscope in the treatment of bile duct stones and cholecystolithiasis in a child: a case report and literature review.

Cholecystolithiasis combined with bile duct stones is more and more common in children, but the surgical treatment is still controversial. We report on a 3-year-old boy, who underwent laparoscope combined with ureteroscope for choledocholithiasis with cholecystolithiasis. This combination therapy offers the possibility to treat pediatric patients with cholecystolithiasis and bile duct stones in low-resource settings where ERCP experience and child-specific surgical instruments are not available. Additionally, a comprehensive review of previous studies was conducted to summarize the surgical treatments. The surgical treatment of children should be made according to the specific situation to maximize the success of the operation and reduce the risk.

Association between visceral lipid accumulation indicators and gallstones: a cross-sectional study based on NHANES 2017-2020.

BACKGROUND: Obesity is a major contributing factor to the formation of gallstones. As early identification typically results in improved outcomes, we explored the relationship between visceral lipid accumulation indicators and the occurrence of gallstones. METHODS: This cross-sectional study involved 3,224 adults. The researchers employed multivariable logistic regression, smoothed curve fitting (SCF), threshold effects analysis, and subgroup analysis to examine the relationship between metabolic scores for visceral fat (METS-VF), waist circumference (WC), lipid accumulation products (LAP), and visceral adiposity index (VAI) and gallstones. A Least Absolute Shrinkage and Selection Operator (LASSO) regression analysis was used to identify key factors which were then used in the construction of a nomogram model. The diagnostic efficacy of this model in detecting gallstones was then determined using receiver operating characteristic curves. RESULTS: Visceral lipid accumulation indicators were strongly linked to the likelihood of having gallstones. Specific saturation effects for METS-VF, WC, LAP, and VAI and gallstones were determined using SCF. The inflection points for these effects were found to be 8.565, 108.400, 18.056, and 1.071, respectively. Subgroup analyses showed that associations remained consistent in most subgroups. The nomogram model, which was developed using critical features identified by LASSO regression, demonstrated excellent discriminatory ability, as indicated by an area under the curve value of 0.725. CONCLUSIONS: Studies have shown that increases in METS-VF, WC, LAP, and VAI are linked to increased prevalences of gallstones. The nomogram model, designed with critical parameters identified using LASSO regression, exhibits a strong association with the presence of gallstones.

Association Between Gallstones and Depressive Symptoms: Results from NHANES and Mendelian Randomization Study.

Purpose: Prior research has suggested a correlation between gallstones and depressive symptoms, yet the specifics of this relationship remain unclear. This study aims to explore the association between gallstones and depressive symptoms among adults. Patients and Methods: Initially, we conducted a cross-sectional study using data from the National Health and Nutrition Examination Survey (NHANES) 2017 - March 2020. After propensity score matching (PSM) for participants with gallstones and those without gallstones, multivariate logistic regression analysis was used to explore the potential association between gallstones and depressive symptoms. This was followed by Mendelian randomization (MR) analysis to further elucidate the causal relationship between them. Using the genome-wide association study database, we extracted instrumental variables and performed bidirectional univariate and multivariate MR analyses. Results: In the cross-sectional study of NHANES 2017 - March 2020, 835 pairs of participants with comparable characteristics, both with and without gallstones, were identified after PSM. The multivariate adjusted logistic regression analyses revealed a significant association between gallstones and depressive symptoms [fully adjusted model: OR=1.821 (95% CI, 1.181-2.808), P=0.007]. Subsequent MR analyses further clarified the causal relationship, indicating that genetically determined gallstones significantly increase the risk of developing depressive symptoms [forward univariate MR analysis: OR=1.04 (95% CI, 1.01-1.06), P=0.002; multivariate MR analysis: OR=1.03 (95% CI, 1.01-1.05), P=0.009], with no evidence of reverse causation [inverse univariate MR analysis: OR=1.28 (95% CI, 0.90-1.83), P=0.17]. Conclusion: Gallstones are a risk factor for depressive symptoms among adults. Hence, we recommend timely depression screening for patients diagnosed with gallstones, facilitating early detection and effective treatment of depressive symptoms, thus alleviating its impact on both individuals and society.

Current evidence on the diagnosis and management of spilled gallstones after laparoscopic cholecystectomy.

BACKGROUND: Despite improvements in intraoperative and postoperative outcomes of laparoscopic cholecystectomy (LC), spilled gallstones (SGs) after LC remain a significant yet often overlooked complication, occurring in 1% to 40% of cases. This review discusses the most recent updates regarding the risk factors, presentations, complications, diagnosis, management, and prognosis of SGs after LC. METHODS: A comprehensive systematic review was conducted using MEDLINE/PubMed, Google Scholar, Cochrane Library, and the Web of Science databases, with the range of search dates being between January 2015 and July 2024, regarding SG incidence, management, and complications. RESULTS: Risk factors for SGs after LC include intraoperative gallbladder perforation because of poor operational environment, quantity, size, and type of stone (pigment, cholesterol rich, or mixed); presence of adhesions or anatomic variations; and insufficient surgical training. Of note, 60% of SG complications are abscesses from bacterial infections, which can progress to peritonitis, fistulas, lung/liver abscesses, and choledocholithiasis. SGs were associated with delayed presentation of unexpected clinical problems, with even diagnosis. Although treatment depends on the severity of the complication, when SGs are identified through imaging, often ultrasound and computed tomography, minimally invasive approaches and antibiotic courses are viable first-line approaches. CONCLUSION: Although LC-associated spillage of gallstones is rare, the complications can be a serious cause of morbidity. Therefore, proper notification of operative complications, a high index of suspicion for patients with a previous history of LC, and awareness of appropriate diagnostic modalities are key variables for the early diagnosis and prevention of SG-related complications.

Assessment of routine pre-operative group and save testing in patients undergoing cholecystectomy: a retrospective cohort study.

Background: Routine group and save (G&S) testing is frequently performed prior to cholecystectomy, despite growing evidence that a targeted approach is safe and avoids unnecessary investigations. This retrospective cohort study explored frequency of testing in our unit, rates of peri-operative blood transfusion and pre-operative risk factors for requiring transfusion. Methods: Health records of 453 consecutive adults who underwent cholecystectomy in a UK NHS trust were reviewed for blood transfusion up to 30 days post-operatively. We compared the need for transfusion against patient demographics, indication and urgency of surgery, and the number of prior emergency hospital attendances with gallstone complications. Logistic regression determined whether prior attendances with complications of gallstones independently predicted the need for transfusion. Results: Peri-operative blood transfusions within 30 days of operation occurred in 1.1% of cases, with no requirement for uncrossmatched blood. Patients who received a blood transfusion tended to have higher American Society of Anesthesiologists (ASA) grades ( p = 0.017), were more likely to have an underlying primary haematological malignancy (20.0% vs. 0.2%; p = 0.022) and prior emergency hospital attendances with gallstone complications (median 4 vs. 1; p < 0.001). Logistic regression showed each prior emergency attendance was associated with 4.6-fold odds of transfusion ( p = 0.019). Receiver operating characteristic curve analysis showed an area under the curve of 0.92. Three or more attendances predicted need for transfusion with 60.0% sensitivity and 98.0% specificity. 74% of patients had at least one G&S sample taken pre-operatively, costing the trust approximately £3,800 per year in materials. Conclusions: The findings of this study suggest that pre-operative G&S testing prior to cholecystectomy is not routinely required. Increased frequency of prior emergency hospital attendances with gallstone complications and co-morbidities associated with coagulopathies were pre-operative risk factors for post-operative blood transfusion. More selective testing could provide large financial savings for health institutions without compromising patient safety.

Many patients diagnosed with gallstones undergo surgery to remove their gallbladder. Blood tests are routinely performed in clinic before the operation, which may include testing a patient's blood type in case of bleeding during or after the operation. This test is required before a patient receives a blood transfusion. Testing the blood type of patients prior to gallbladder surgery may not be routinely required, as excessive bleeding from this operation is rare. Avoiding unnecessary blood tests protects patients from unwarranted needles, prevents delays to surgery and saves hospitals money. We therefore investigated how frequently patients undergoing gallbladder surgery in our unit have blood type testing. We also assessed how often patients require a blood transfusion and whether testing for blood type could have been safely performed once the need for transfusion was identified, instead of before the operation. Looking back at 453 patients' notes, we found that only five needed a blood transfusion within 30 days of their operation. None of these blood transfusions were needed on an emergency basis, and therefore there would have been enough time to test these patients for their blood type without having to test them before the operation. Despite this, nearly three-quarters of our patients had blood type testing before the operation. Each of these tests costs an estimated £11 per sample in our unit, and therefore £3,800 per year could have been saved were these tests not performed. The five patients who required a transfusion were found to have attended hospital more times before their operation with problems related to gallstones. Therefore, our study provides evidence that performing gallbladder operations on a more urgent basis following an admission to hospital with gallstone complications could reduce a patients' risk of bleeding.

Surgical Management of Gallstone Ileus: Approach, Outcome, Case Report, and Literature Review.

Gallstone ileus (GSI) is a condition caused by migrating gallstones lodged in the terminal ileum. Stone migration results from fistula formation, typically between the gallbladder and duodenum, termed a cholecystoduodenal fistula. This mechanical obstruction has high mortality and requires prompt intervention. This discussion focuses on two GSI cases caused by cholecystoduodenal fistula managed by the surgical removal of the mechanical obstruction and a conservative approach to the fistula. Patient 1 is a 51-year-old male with no significant past medical history. After radiological imaging and laboratory findings raised concern for cholecystoduodenal fistula, the patient underwent a diagnostic laparoscopy with small bowel resection. The second patient is a 74-year-old female with a past medical history of hypertension, myocardial infarction, and laparoscopic uterine lift. The patient underwent diagnostic laparoscopy, lysis of adhesions, mini-laparotomy, and segmental small bowel resection with primary anastomosis. Many factors lead to gallstone formation, including gender, genetics, ethnicity, etc. Fistulas are formed from chronic inflammation and tissue necrosis from gallstone pressure on surrounding tissue. Classic radiologic findings of GSI are pneumobilia, bowel obstruction, and gallstones outside the gallbladder. The most common approach to GSI management is solely relieving the mechanical obstruction by an enterotomy proximal to the obstruction, associated with reduced mortality. Both patients had good outcomes which we attributed to our surgical removal of the small bowel obstruction and a non-operative approach to the cholecystoduodenal fistula.

Open versus laparoscopic completion cholecystectomy in patients with previous open partial cholecystectomy: a retrospective comparative study.

Background: Some patients report recurrence or persistence of their manifestations after cholecystectomy, and retained gallstones may be a relevant etiology for their complaint. Completion cholecystectomy is advised for these cases to alleviate their manifestations. No previous studies have compared the outcomes of open versus laparoscopic outcomes in these patients, especially in patients who had initial open partial procedures. That is why we performed this study to report the perioperative outcomes of the two approaches in such patients. Methodology: This is a retrospective analysis of 80 patients who had a completion cholecystectomy in the authors' center (40 open and 40 laparoscopic cases) after initial open partial cholecystectomy. Results: The duration elapsed since the primary procedure had an average of 18 months in the open group and 21 months in the laparoscopic group. Abdominal pain and dyspepsia were the most common presentations. Some patients had stump cholecystitis or jaundice. The intraoperative assessment revealed either the residual gallbladder or a long cystic duct stump. Laparoscopy yielded shorter operative time, earlier oral intake, and shorter hospitalization periods compared to the open approach (P<0.05). The latter was associated with a 20% wound infection rate that was never encountered after laparoscopy (P =0.003). Conclusion: Previous open partial cholecystectomy does not hinder subsequent laparoscopic completion cholecystectomy. Additionally, laparoscopy is associated with better perioperative outcomes than the open approach.

Association between serum iron and gallstones in US adults: a cross-sectional study.

BACKGROUND: Gallstones are a common digestive disorder that threatens human health. Iron deficiency may be related to the formation of gallstones, but there is limited current epidemiological research. The objective of this study was to investigate the relationship between iron status and gallstones. METHODS: The datasets from the National Health and Nutrition Examination Survey (NHANES) 2017-2020 were used in a cross-sectional investigation. Gallstones were determined by using the 2007-2010 NHANES questionnaire. Multivariate linear regression models were used to examine the association between serum iron, serum ferritin and iron intake with the risk for gallstones. Subgroup analysis based on gender, age, race, and diabetes were performed. Fitted smoothing curves were used to describe the linear relationship. RESULTS: The research involved 7847 participants aged 20 and above, among whom 845 were identified as having gallstones. Participants with higher serum iron levels tended to have a lower gallstones prevalence. A negative relationship between serum iron and gallstones prevalence was observed (OR = 0.979, 95% CI:0.965-0.992). The group with the highest serum iron tertile had a 23.7% lower risk of gallstones compared to the lowest tertile (OR = 0.763, 95% CI:0.628‒0.929). Gallstone prevalence was inversely correlated with iron intake in model 1. The negative association between serum iron and gallstones remained stable in stratifications, including gender, age, race, and diabetes. CONCLUSIONS: Elevated serum iron was associated with a decreased prevalence of gallstones. However, to confirm the impact of long-term iron metabolism on gallstone formation, additional prospective research is necessary.

Practices in the Management of Incidental Gallbladder Cancer.

Peeyush VarshneyBackground Histopathology of gallbladder removed for stones may reveal incidental gallbladder cancer (iGBC). We conducted this online e-survey to document the knowledge and practices of management of iGBC among surgeons in India. Methods A 38-question online e-survey Results Two-hundred thirty responses were recorded. Ninety-eight out of two-hundred (49%) responses were general surgeons. Two-hundred ten out of two-hundred twenty-one (95%) saw at least one iGBC per year, but only 74/225 (32%) correctly defined true iGBC. One-hundred seventy-eight out of two hundred twenty-two (80%) did computed tomography/magnetic resonance imaging for thick-walled gallbladder (GB) detected on ultrasound, while 25/222 (11%) did laparoscopic cholecystectomy and 14/222 (6%) did open cholecystectomy. For GB mass on laparoscopy, 16/222 (7%) responses went ahead with simple cholecystectomy. Seventy-four out of two-hundred twenty-five (32%) responses routinely used bag while extracting GB. One-hundred ninety-one out of two-hundred twenty-five (86%) mentioned about stone/bile spill, 121/220 (55%) mentioned about use of bag for extraction while 137/220 62% mentioned port used for extraction of GB in operation notes. One-hundred sixty-six out of two-hundred twenty-seven (73%) always cut open GB after cholecystectomy. On encountering a mass/lesion on cut open GB, 111/225 (49%) sent it for frozen section, 89/225 (40%) sent for routine histopathology while 10% (22/225) directly proceeded for extended cholecystectomy. Ten out of two-hundred twenty-seven (4.4%) did not consider it important to send GB for histopathology. T stage on histopathology is most important factor for deciding reoperation by 205/223 (91%). Conclusion There are lacunae in understanding and deficiencies in management of iGBC in India-a high GBC incidence country. The situation is likely to be worse in low GBC incidence areas. There is need for more awareness and knowledge for proper management of iGBC among surgeons.

The association between vitamin D consumption and gallstones in US adults: A cross-sectional study from the national health and nutrition examination survey.

BACKGROUND: Gallstone disease is common in the US and Europe. Gallstones are associated with factors such as age, sex, weight, and serum cholesterol levels. A complex relationship exists between vitamin D levels and cholesterol metabolism. However, the relationship between vitamin D level and gallstones remains unclear. This study aimed to investigate whether gallstones are associated with dietary vitamin D (D2+D3) consumption (VDC) in American adults. METHODS: This cross-sectional study used data from people who participated in the National Health and Nutrition Examination Survey between March 2017 and March 2020. Multivariate logistic regression models were used to determine the association between vitamin D intake and the presence of gallstones. Stratified and interaction analyses were performed to determine whether the relationship was stable across different subgroups. RESULTS: 6873 participants were included. VDC (per 1 SD) was positively associated with gallstones in the crude model (OR: 1.11, 95% Confidence Interval (CI): (1.05-1.17); p < 0.001), Further adjustment did not affect the results. When vitamin D was analyzed using quartiles, with increased quartile of VDC, the incidence of gallstones increased, and the OR of Q2 (OR: 1.08, 95% CI: 0.89-1.32, p = 0.436) and Q3 (OR: 1.55, 95% CI: 1.28-1.87, p < 0.001) was higher than that of Q1 in crude model. After adjusting for covariates, there is a positive association between VDC and incidence of gallstones without statistical significance. CONCLUSION: VDC was positively associated with the incidence of gallstones, however, further studies are required to gather additional evidence.

The link between serum cotinine levels and gallstones prevalence in adults: a cross-sectional analysis using NHANES data (2017-2020).

Background: Gallstones represent a prevalent health issue globally, resulting in significant annual healthcare costs. While tobacco exposure is recognized for its association with numerous diseases, its correlation with gallstones remains contentious. Serum cotinine, a metabolite of nicotine, serves as a widely utilized indicator for assessing tobacco exposure. Crucially, no research has yet examined the association between serum cotinine levels and the gallstones. Methods: This study is designed as a cross-sectional analysis, utilizing data from the NHANES public database. The relationship between serum cotinine levels and gallstones was analyzed using multinomial logistic regression models and smooth curve fitting. Subgroup analyses and interaction tests were performed to examine the potential contributions of different populations and covariates to the findings. Results: A total of 5,856 participants were included in this study. After adjusting for relevant covariates, the multiple logistic regression model results indicated that for each unit increase in serum cotinine concentration above 0.29 ng/mL, there was a 29% increase in the prevalence of gallstones. Furthermore, smooth curve fitting analysis revealed a positive correlation between these variables. These findings underscore the impact of tobacco exposure on gallstone prevalence. Conclusion: This study demonstrates a positive correlation between tobacco exposure, as measured by serum cotinine levels, and the prevalence of gallstones, thus adding to the body of existing research on this relationship.

Day-case laparoscopic cholecystectomy in the management of gallbladder disease: a literature review.

BACKGROUND: Day-case laparoscopic cholecystectomy (DCLC) has gained traction globally due to its benefits, including shorter hospital stays, reduced costs, and enhanced patient experience. While concerns about patient safety, particularly related to bleeding and bile duct injury persist, the literature supports the efficacy and advantages of DCLC highlighting the need for its wider adoption in healthcare settings to optimise resources and improve patient outcomes. METHODS: This was a literature review that aims to assess the feasibility and safety of day-case laparoscopic cholecystectomy for symptomatic gallstone patients, focusing on incidence and aetiology of unexpected admissions and readmissions, as well as conversion-to-open rates. PubMed was searched for all studies focusing on DCLC between 2014 and 2024. The timeframe was specifically selected to identify recent trends and practices in this evolving field. By focusing on this specific period, the review aims to provide a comprehensive analysis of current practices, emerging trends, and the evolving standard of care in this area. RESULTS: This review highlights that the main causes of unexpected admission post DCLC were postoperative nausea, vomiting, and pain, while the implementation of anaesthetic pathways notably increased day-case rates. Studies addressing complication rates postoperatively consistently found no significant difference between day-case and in-patient procedures. CONCLUSIONS: DCLC for symptomatic gallstone patients is supported by research as safe and effective, with high success rates and patient satisfaction. Studies show minimal complications and acceptable readmission rates, suggesting that DCLC can be the standard approach for selective patients, improving outcomes and healthcare efficiency.

Association between lipid accumulation products and gallstones: an analysis of the National Health and Nutrition Examination Survey 2017-2020.

AIMS: The aim of the research was to look into the connection between the occurrence of gallstones in adult US citizens and lipid accumulation products (LAP). METHODS: We conducted a cross-sectional study of 3,582 U.S. adults with relevant indicators collected from the 2017-2020 National Health and Nutrition Examination Survey (NHANES) database. Multifactorial logistic regression was used to investigate the linear relationship between LAP and gallstone incidence, while smoothed curve fitting was used to describe the nonlinear relationship, and subgroup and interaction analyses were used to evaluate the potential differences between groups. RESULTS: Among the 3582 participants aged ≥ 20 years included, there was a positive association between LAP and gallstones. Following adjustments for all covariates, the likelihood of getting gallstones rose by 29% for each unit rise in log2-LAP (OR = 1.29, 95% CI: 1.13‒1.49). Compared to those in the lowest tertile, those in the highest LAP tertile had a significantly higher risk of developing gallstones (OR = 1.97, 95% CI: 1.31‒2.95). Subgroup analyses indicated that the association between LAP and gallstones was not affected by the stratification of the variables examined. CONCLUSION: Gallstones and LAP exhibited a positive association in our investigation, indicating that LAP may be utilized as a clinical indicator to determine the occurrence of gallstones.

Accumulation of rare earth elements in human gallstones: a perspective from dietary and human health.

BACKGROUND: Gallstone disease poses a global threat to human health and is strongly linked to environmental factors. However, there is currently no data on the presence of rare earth elements (REEs) in human gallstones. This paper investigates the concentration and distribution of REEs in gallstones for the first time, aiming to explore the environmental implications on human health. METHODS: A total of 25 gallstone samples were collected in Shanghai and the content of REEs was measured by Inductively coupled plasma-Mass Spectrometry (ICP-MS) to explore the distribution of REEs in gallstones. RESULTS: The concentration of REEs in gallstones ranged from 4.89 to 190.8 ng/g (mean 39.21). In most of the gallstone analyses, REEs have been detected and generally attributed to environmental exposure or food contamination. The Y/Ho ratio of gallstones was lower than that of continental rocks, similar to that in the blood, indicating limited fractionation during fluid transport processes in the gallbladder. CONCLUSIONS: The upper continental crust (UCC)-normalized REEs pattern in gallstones showed depletion of light REEs, while most showed enrichment of heavy REEs. Positive Gd anomalies were found in most samples, while few samples suggested anthropogenic influence. Whether exogenous inputs or in vivo biofractionation lead to changes in REEs fractionated patterns require further analyses.

Utility of Common Bile Duct Identification on Biliary Ultrasound in Emergency Department Patients.

Background: Biliary ultrasound is often utilized in the evaluation of abdominal pain in the Emergency Department (ED). Common bile duct (CBD) identification is traditionally a standard component of the biliary ultrasound examination but can be challenging to perform for the novice sonographer. Previous work has demonstrated that CBD dilatation is rare in cases of cholecystitis with normal liver function tests (LFTs). We sought to assess the frequency of CBD dilatation in the subset of ED patients undergoing hepatobiliary ultrasound who have normal LFTs and an absence of gallstones or biliary sludge on ultrasound. We also performed an assessment of changes in CBD diameter by age and cholecystectomy status. Methods: This was a retrospective chart review at a single academic ED. Patients were enrolled in the study if they underwent a radiology performed (RP) hepatobiliary ultrasound within the 2 year study period. Records were reviewed for the presence of gallstones or sludge, CBD diameter, age, clinical indication for the ultrasound, and LFTs. Descriptive analyses were performed, and interobserver agreement among data abstractors was assessed by K analysis for the presence of CBD dilatation. The Mann-Whitney test was utilized to assess statistical significance in the comparison of differences between CBD diameters amongst age groups. Results: Of 1929 RP hepatobiliary ultrasounds performed in the study period, 312 were excluded and 1617 met inclusion criteria. Amongst these, there were 506 patients who had normal LFTs and an ultrasound with no stones or sludge. Ten patients within this group had a dilated CBD > 7 mm (1.98%, 95% CI of 1.08% to 3.6%). We also noted a statistically significant increase in CBD size in the older age cohort and in those individuals with a history of cholecystectomy. Conclusion: CBD dilation in ED patients who present with normal LFTs and an absence of gallstones and biliary sludge is rare. Physicians should be reassured that the routine identification of the CBD on ultrasound in this setting is of low yield and need not be pursued.

The common bile duct is often taught as part of the biliary point-of-care ultrasound examination. However, it is more challenging to identify than the gallbladder and thus may limit adoption of POCUS by ED physicians. Our study adds to the body of work demonstrating that omitting the common bile duct from an ultrasound evaluation is likely reasonable when both the gallbladder and liver function tests are normal. Our study also adds to the literature regarding the increase in common bile duct size with age and with post-cholecystectomy status.
