After cholecystectomy, elderly patients require special attention, due to the influence of involution processes in the body on the formation of complications. To identify prognostic criteria for the formation of fatty liver degeneration in the long-term period of minimally invasive cholecystectomy, 159 men were examined. Dysregulation of the biliary tract was determined using magnetic resonance cholangiopancreatography, elastography and magnetic resonance imaging of the liver. Microbial markers of the wall microbiome of the intestine were determined using chromatography-mass spectrometry. The relationship between an increase in body mass index and a decrease in the amount of obligate microbiome (r=-0,43, p<0,050), as well as with the formation of fatty liver degeneration in elderly patients, was revealed. The features of vegetative regulation in elderly people with fatty liver degeneration have been determined. It has been proven that in old age, a decrease in the number of obligate anaerobic association of microorganisms of the small intestine (on average from 15 659 to 7 630 in persons of the 2nd age subgroup and from 1 457 to 17 837 in the 3rd) is a predictor of fatty liver degeneration. The prognostic algorithm developed on the basis of the analysis of highly informative signs makes it possible to identify with an accuracy of at least 75% a high risk of fatty liver degeneration in the long-term period of cholecystectomy.
После холецистэктомии больные пожилого возраста требуют особого внимания из-за влияния инволюционных процессов в организме на формирование осложнений. Для выявления прогностических критериев формирования неалкогольной жировой болезни печени (НАЖБП) в отдаленном периоде мини-инвазивной холецистэктомии были обследованы 159 мужчин. Нарушение регуляции желчевыводящих путей определяли с помощью магнито-резонансной хoлaнгиoпaнкреатoграфии, эластографии и МРТ печени. Микробные маркеры пристеночного микробиома кишечника определяли с помощью хромато-масс-спектрометрии. Выявлена взаимосвязь повышения ИМТ со снижением количества облигатного микробиома (r=–0,43, p<0,050), а также с формированием НАЖБП у пожилых пациентов. Определены особенности вегетативной регуляции у пожилых лиц с НАЖБП. Доказано, что в пожилом возрасте снижение количества облигатной анаэробной ассоциации микроорганизмов тонкой кишки (в среднем с 15 659 до 7 630 кл./г∙105 у лиц 2-й возрастной подгруппы, и с 1 457 до 17 837 кл./г∙105 — в 3-й) является предиктором НАЖБП. Разработанный на основании анализа высокоинформативных признаков прогностический алгоритм позволяет с точностью не ниже 75% выявить высокий риск формирования НАЖБП в отдалённом периоде холецистэктомии.

UNASSIGNED: Gallstone disease is a common gastrointestinal disorder in industrialised societies. The prevalence of gallstones in the adult population is estimated to be approximately 10-15%, and around 80% remain asymptomatic. At present, cholecystectomy is the default option for people with symptomatic gallstone disease.
UNASSIGNED: To assess the clinical and cost-effectiveness of observation/conservative management compared with laparoscopic cholecystectomy for preventing recurrent symptoms and complications in adults presenting with uncomplicated symptomatic gallstones in secondary care.
UNASSIGNED: Parallel group, multicentre patient randomised superiority pragmatic trial with up to 24 months follow-up and embedded qualitative research. Within-trial cost-utility and 10-year Markov model analyses. Development of a core outcome set for uncomplicated symptomatic gallstone disease.
UNASSIGNED: Secondary care elective settings.
UNASSIGNED: Adults with symptomatic uncomplicated gallstone disease referred to a secondary care setting were considered for inclusion.
UNASSIGNED: Participants were randomised 1: 1 at clinic to receive either laparoscopic cholecystectomy or observation/conservative management.
UNASSIGNED: The primary outcome was quality of life measured by area under the curve over 18 months using the Short Form-36 bodily pain domain. Secondary outcomes included the Otago gallstones\' condition-specific questionnaire, Short Form-36 domains (excluding bodily pain), area under the curve over 24 months for Short Form-36 bodily pain domain, persistent symptoms, complications and need for further treatment. No outcomes were blinded to allocation.
UNASSIGNED: Between August 2016 and November 2019, 434 participants were randomised (217 in each group) from 20 United Kingdom centres. By 24 months, 64 (29.5%) in the observation/conservative management group and 153 (70.5%) in the laparoscopic cholecystectomy group had received surgery, median time to surgery of 9.0 months (interquartile range, 5.6-15.0) and 4.7 months (interquartile range 2.6-7.9), respectively. At 18 months, the mean Short Form-36 norm-based bodily pain score was 49.4 (standard deviation 11.7) in the observation/conservative management group and 50.4 (standard deviation 11.6) in the laparoscopic cholecystectomy group. The mean area under the curve over 18 months was 46.8 for both groups with no difference: mean difference -0.0, 95% confidence interval (-1.7 to 1.7); p-value 0.996; n = 203 observation/conservative, n = 205 cholecystectomy. There was no evidence of differences in quality of life, complications or need for further treatment at up to 24 months follow-up. Condition-specific quality of life at 24 months favoured cholecystectomy: mean difference 9.0, 95% confidence interval (4.1 to 14.0), p < 0.001 with a similar pattern for the persistent symptoms score. Within-trial cost-utility analysis found observation/conservative management over 24 months was less costly than cholecystectomy (mean difference -£1033). A non-significant quality-adjusted life-year difference of -0.019 favouring cholecystectomy resulted in an incremental cost-effectiveness ratio of £55,235. The Markov model continued to favour observation/conservative management, but some scenarios reversed the findings due to uncertainties in longer-term quality of life. The core outcome set included 11 critically important outcomes from both patients and healthcare professionals.
UNASSIGNED: The results suggested that in the short term (up to 24 months) observation/conservative management may be a cost-effective use of National Health Service resources in selected patients, but subsequent surgeries in the randomised groups and differences in quality of life beyond 24 months could reverse this finding. Future research should focus on longer-term follow-up data and identification of the cohort of patients that should be routinely offered surgery.

The C-GALL study assessed the benefits, in terms of symptoms, quality of life and costs, of cholecystectomy versus observation (conservative management: by the patient and general practitioner that might include dietary advice and pain management and surgery if needed). Four hundred and thirty-four patients with symptomatic gallstones were randomly allocated surgery or conservative management. The main symptom of ongoing bodily pain and some other quality-of-life measures were assessed over the next 2 years using postal questionnaires. After 2 years, 70% of those allocated to surgery had been operated on and 37% of the observation group either had an operation or were waiting for one. There was no difference in bodily pain or overall quality of life between the groups. However, participants in the surgery group reported fewer ongoing problems related to their gallstone disease or after surgery than those in the conservative management group. Surgery was, however, more costly than conservative management. The C-GALL study has shown that for some patients, a conservative management approach may be a sufficient and less costly way of managing their gallstone symptoms rather than going straight on the waiting list for surgery. More research is needed to identify which patients benefit most from surgery.

Telocytes are closely associated with the regulation of tissue smooth muscle dynamics in digestive system disorders. They are widely distributed in the biliary system and exert their influence on biliary motility through mechanisms such as the regulation of CCK and their electrophysiological effects on smooth muscle cells. To investigate the relationship between telocytes and benign biliary diseases,such as gallbladder stone disease and biliary dilation syndrome, we conducted histopathological analysis on tissues affected by these conditions. Additionally, we performed immunohistochemistry and immunofluorescence double staining experiments for telocytes. The results indicate that the quantity of telocytes in the gallbladder and bile duct is significantly lower in pathological conditions compared to the control group. This reveals a close association between the decrease in telocyte quantity and impaired gallbladder motility and biliary fibrosis. Furthermore, further investigations have shown a correlation between telocytes in cholesterol gallstones and cholecystokinin-A receptor (CCK-AR), suggesting that elevated cholesterol levels may impair telocytes, leading to a reduction in the quantity of CCK-AR and ultimately resulting in impaired gallbladder motility.Therefore, we hypothesize that telocytes may play a crucial role in maintaining biliary homeostasis, and their deficiency may be associated with the development of benign biliary diseases, including gallstone disease and biliary dilation.

Nutritional exposure is considered the main environmental influence that contributes to gallstone disease (GD).
The aim of this study was to determine food intakes patters and estimate risk of GD.
A nested case-control study was carried out within the framework of a previous screening study conducted on a representative sample in Rosario, Argentina. Participants underwent a personal interview. Average amount of each food intake and quantity nutrients were estimated applying a food-frequency questionnaire. Food consumption patterns were identified by principal component analysis, and logistic regression analysis was used to estimate risks.
The sample was conformed by 51 cases and 69 controls. Two dietary patterns were identified. Cases were characterised by the unhealthy intake pattern (high intakes of animal fats, sugar, cereals, grains, cold cuts, processed meats, chicken with skin, fat beef and low intake of red vegetables and yellows, cabbages, fruits and fish).
Controls were characterised by the healthy intake pattern (high intake of skinless chicken, nuts, lean beef, vitamin A and C rich fruits, and low consumption of chicken with skin, green leaves vegetables and sprouts). The unhealthy pattern showed an increased risk of developing GD while healthy patter behaved as a protective factor.
La exposición nutricional se considera la principal exposición ambiental que contribuye a la formación de cálculos biliares.
El objetivo de este trabajo fue determinar el patrón de consumo alimentario de casos y controles de EC y estimar el riesgo de desarrollar la enfermedad según los distintos patrones constituidos.
Se llevó a cabo un estudio analítico retrospectivo transversal de casos y controles, anidado a un estudio de prevalencia realizado en Rosario. Todos los participantes fueron entrevistados personalmente. El consumo de alimentos se consignó a través de un cuestionario semi-cuantitativo de frecuencia de consumo. Para determinar patrones de consumo alimentario se realizó un análisis de componentes principales, y análisis de regresión logística múltiple para evaluar riesgos.
La muestra quedó conformada por 51 casos y 69 controles. Se determinaron dos componentes que permitían diferenciar los casos de los controles, a través de las cuales se establecieron 2 patrones de consumo. Los casos se caracterizaron por un consumo determinado por el Patrón Poco saludable (altas ingestas de grasas animales, azúcar, cereales, granos, fiambres y embutidos) y los controles por el consumo del patrón Saludable (altas ingestas de pollo sin piel, frutas secas, carne vacuna magra, frutas, lácteos enteros). El patrón Poco saludable, aumentó el riesgo de desarrollar EC mientras que el patrón Saludable, se comportó como protector.
Los patrones constituidos diferencian los casos de los controles, y la ingesta propia de los casos se correlaciona con un perfil de consumo que caracteriza a las culturas occidentales modernas y urbanas.

UNASSIGNED: Epidemiological studies show dietary habits can have an impact on the risk of cholelithiasis, but the relationship is still unclear. We used a comprehensive Mendelian randomization (MR) study to explore the relationship between dietary habits and cholelithiasis.
UNASSIGNED: The 18 dietary habits were divided into six categories: meat foods, cereals, vegetables, fruits, dairy products, beverages, and condiments. Cholelithiasis data came from a GWAS meta-analysis and the FinnGen consortium. The inverse variance weighted (IVW), the weighted median (WM), and MR-Egger approaches were used as the main MR analysis methods. In addition, multiple sensitivity analysis and meta-analysis were performed to verify the robustness of the results.
UNASSIGNED: Dried fruit intake [odds ratio (OR) = 0.568; 95% confidence interval (CI), 0.405-0.797; p = 0.001] was discovered to reduce the risk of cholelithiasis. The sensitivity analysis and meta-analysis showed reliable results for the relationship between dried fruit intake and cholelithiasis.
UNASSIGNED: Our study found that dried fruit intake is a protective factor in the development of cholelithiasis. However, the mechanisms of action need to be further explored.

Cholelithiasis is a common biliary tract disease. However, the exact mechanism underlying gallstone formation remains unclear. Mucin plays a vital role in the nuclear formation and growth of cholesterol and pigment stones. Excessive mucin secretion can result in cholestasis and decreased gallbladder activity, further facilitating stone formation and growth. Moreover, gallstones may result in inflammation and the secretion of inflammatory factors, which can further increase mucin expression and secretion to promote the growth of gallstones. This review systematically summarises and analyses the role of mucins in gallstone occurrence and development and its related mechanisms to explore new ideas for interventions in stone formation or recurrence.

OBJECTIVE: Cysteine protease caspase-1 (Casp1) plays a crucial role in the conversion of pro-cytokines to active cytokines (CYTs). The purpose of this work was to determine Casp1 blood levels in a cohort of 114 cholecystectomy patients and assess their association with other CYTs and numeric rating scale (NRS) pain scores, postoperatively.
METHODS: Blood levels of Casp1 and seven CYTs (IL-18, IL-18BP, IL-1ra, IL-6, IL-10, IL-1β, and IL-8) were measured at three time points; before operation, immediately after operation, and six hours after operation in 114 patients with cholelithiasis (Chole).
RESULTS: Casp1 blood levels correlated with NRS pain scores at 24 h following surgery (p=0.016). In addition, Casp1 blood levels correlated significantly to IL-18 blood levels (p<0.001).
CONCLUSIONS: This is the first report to evaluate Casp1 blood levels in Chole patients in correlation with other CYTs. The findings confirm a significant correlation between Casp1 blood levels and NRS pain scores. Moreover, this study provides initial evidence suggesting that inhibition of the activity of Casp1 may reduce postsurgical acute phase immune response possibly through the Casp1/pro-Il-18 pathway.

Hemorrhagic pancreatitis following endoscopic retrograde cholangiopancreatography (ERCP) is an adverse event that has received limited attention in medical studies. We describe a 28-year-old female who was admitted with symptoms of abdominal pain, nausea, and vomiting, along with tenderness in the right upper quadrant upon physical examination. CT abdomen revealed the presence of a gallstone obstructing the common bile duct. The patient underwent an ERCP procedure, which included a biliary sphincterotomy and the balloon-assisted removal of the obstructing stone. Unfortunately, the procedure was complicated with acute pancreatitis characterized by fluid accumulation in the abdomen, suggestive of hemorrhagic pancreatitis. There was a notable decrease in hemoglobin levels and hypotension, indicating the need for a higher level of care. Patients were managed conservatively with hydration and pain control. Follow-up in the clinic confirmed the resolution of symptoms and stabilization of the hemoglobin. Prompt recognition of post-ERCP hemorrhagic pancreatitis is crucial and warrants a high index of suspicion. Furthermore, the discussion explored the various risk factors and pathological events behind post-ERCP pancreatitis to understand the mechanisms of the disease. Various previously used intervention and prevention strategies were critically discussed for the awareness of future researchers and healthcare practitioners.

UNASSIGNED: Exposure to a mixture of environmental chemicals may cause gallstone, but the evidence remains equivocal. The current study aims to investigate the association between phthalate metabolites and gallstones, and to explore their mediators.
UNASSIGNED: Data from the National Health and Nutrition Examination Survey 2017-2018 on U.S. adults (≥20 years) were analyzed to explore the association between phthalate metabolites and gallstones by employed survey-weighted logistic regression, restricted cubic spline (RCS), weighted quantile sum (WQS) regression, and Bayesian kernel machine regression (BKMR). Mediation analyses examined the role of oxidative stress markers, inflammatory markers, metabolic syndrome, body composition, diabetes, and insulin.
UNASSIGNED: The current study included 1,384 participants, representing 200.6 million U.S. adults. Our results indicated a significant association between phthalate metabolites, particularly high molecular weight metabolites such as Di(2-ethylhexyl) phthalate (DEHP) and 1,2-Cyclohexane dicarboxylic acid diisononyl ester (DINCH), and gallstones. Furthermore, mediation analyses indicated that phthalate metabolites may play a role in the development of gallstones by influencing insulin secretion. Subgroup analyses did not reveal significant interaction.
UNASSIGNED: The association between exposure to phthalates and the occurrence of gallstones, potentially mediated by hyperinsulinemia from a nationally representative epidemiological perspective. These insights contribute to a better understanding of the potential health implications of plasticizers, emphasizing the need for proactive management measures.

The crystalization of the components of bile within the gallbladder can lead to the formation of gallstones (cholelithiasis), which may often require surgical removal of the gallbladder, a procedure known as cholecystectomy, in symptomatic cases. Robotic single-site cholecystectomy (RSSC) is a recently introduced groundbreaking minimally invasive procedure for gallbladder removal. RSSC utilizes robotic technology, offering enhanced dexterity through a single-incision approach, promising improved outcomes such as reduced postoperative pain and superior cosmesis. However, certain limitations, such as restricted instrument movement and heightened hernia risk, necessitate a critical evaluation of this modality. Furthermore, as the widespread adoption of RSSC remains undecided due to concerns over its costs, efficiency, and overall superiority over prior models, this paper assesses future possibilities for RSSC\'s evolution. In vivo robotics, improved digital imaging, and re-engineering of the surgical instruments themselves are all potential avenues to augment the current RSSC design, although it is currently unclear as to what extent they could impact the procedure\'s viability. This review critically examines the available literature on the effectiveness and potency of RSSC compared to its predecessors in the modern healthcare setting and proposes future directions through which innovation could more firmly establish the procedure as the standard of care for cholecystectomy.
