RESUMO
The gallstone disease is becoming increasingly prevalent worldwide. Dietary trace minerals have been proven to be closely related to many metabolic diseases, and this study aims to explore the association between intakes of dietary trace minerals (copper, iron, selenium, and zinc) and gallstone disease (GSD). Using the National Health and Nutrition Examination Survey (NHANES) from 2017 to 2018, intakes of dietary trace minerals and GSD data were obtained through a 24-hour recall and diagnostic questionnaire, respectively. Weighted logistic regression models were used to identify the association between intakes of dietary trace minerals and the prevalence of GSD, and the results were presented as odds ratios (OR) and 95% confidence intervals (95% CI). A total of 4077 participants were included in the final analysis, of which 456 participants had GSD and 3621 participants serving as the control group. No significant associations between GSD and intakes of dietary trace minerals (iron, selenium, and zinc) were found. However, after adjusting for all covariates, significant association was demonstrated between dietary copper (Cu) intake and GSD (ORâ =â 0.66, 95% CIâ =â 0.45-0.98). After conducting a weighted quantile logistic regression, a significant negative correlation was also found between dietary Cu intake and highest GSD quartile (Q4) (ORâ =â 0.45, 95% CIâ =â 0.26-0.80). Following the research outlined above, no association was found between intakes of dietary trace minerals (iron, selenium, and zinc) and GSD; however, a linear negative association was identified between dietary Cu intake and GSD.

Cholelithiasis is a common and frequently occurring disease worldwide that belongs to the category of jaundice in traditional Chinese medicine. Yinchenhao decoction (YD) consists of Artemisia capillaris Thunb., Gardenia jasminoides J.Ellis, and Rheum palmatum L., and is traditionally used to treat jaundice, which has a significant therapeutic effect on cholelithiasis. Our study aimed to investigate the pathological mechanism of cholelithiasis and the therapeutic mechanism of YD via mucin in the gallbladder and intestine. YD was prepared and analyzed using HPLC. The supersaturation stability experiment was designed by the solvent-shift method. The cell transport experiment was conducted by coculture monolayers. The animal experiment was performed using a cholelithiasis model with a high-cholesterol diet. The related indicators were detected by automatic biochemical analyzer, PCR, western blot, or ELISA. Statistics were analyzed using χ2-tests and t-tests. As the results, in cholelithiasis, MUC5AC highly expressed in the gallbladder shortened cholesterol supersaturation and promoted cholesterol crystallization via the inflammatory cytokine signaling pathway; MUC2 highly expressed in the small intestine prolonged cholesterol supersaturation and promoted cholesterol absorption via the inflammatory cytokine signaling pathway. YD inhibited mucin expression in the gallbladder and intestine in a concentration-dependent manner for cholelithiasis treatment by inhibiting the inflammatory cytokine signaling pathway, which was attributed to the active components, including chlorogenic acid, geniposide, and rhein.

BACKGROUND: Fatty acids are important dietary factors that have been extensively studied for their implication in health and disease. Evidence from epidemiological studies and randomised controlled trials on their role in cardiovascular, inflammatory, and other diseases remains inconsistent. The objective of this study was to assess whether genetically predicted fatty acid concentrations affect the risk of disease across a wide variety of clinical health outcomes. METHODS AND FINDINGS: The UK Biobank (UKB) is a large study involving over 500,000 participants aged 40 to 69 years at recruitment from 2006 to 2010. We used summary-level data for 117,143 UKB samples (base dataset), to extract genetic associations of fatty acids, and individual-level data for 322,232 UKB participants (target dataset) to conduct our discovery analysis. We studied potentially causal relationships of circulating fatty acids with 845 clinical diagnoses, using mendelian randomisation (MR) approach, within a phenome-wide association study (PheWAS) framework. Regression models in PheWAS were adjusted for sex, age, and the first 10 genetic principal components. External summary statistics were used for replication. When several fatty acids were associated with a health outcome, multivariable MR and MR-Bayesian method averaging (MR-BMA) was applied to disentangle their causal role. Genetic predisposition to higher docosahexaenoic acid (DHA) was associated with cholelithiasis and cholecystitis (odds ratio per mmol/L: 0.76, 95% confidence interval: 0.66 to 0.87). This was supported in replication analysis (FinnGen study) and by the genetically predicted omega-3 fatty acids analyses. Genetically predicted linoleic acid (LA), omega-6, polyunsaturated fatty acids (PUFAs), and total fatty acids (total FAs) showed positive associations with cardiovascular outcomes with support from replication analysis. Finally, higher genetically predicted levels of DHA (0.83, 0.73 to 0.95) and omega-3 (0.83, 0.75 to 0.92) were found to have a protective effect on obesity, which was supported using body mass index (BMI) in the GIANT consortium as replication analysis. Multivariable MR analysis suggested a direct detrimental effect of LA (1.64, 1.07 to 2.50) and omega-6 fatty acids (1.81, 1.06 to 3.09) on coronary heart disease (CHD). MR-BMA prioritised LA and omega-6 fatty acids as the top risk factors for CHD. Although we present a range of sensitivity analyses to the address MR assumptions, horizontal pleiotropy may still bias the reported associations and further evaluation in clinical trials is needed. CONCLUSIONS: Our study suggests potentially protective effects of circulating DHA and omega-3 concentrations on cholelithiasis and cholecystitis and on obesity, highlighting the need to further assess them as prevention treatments in clinical trials. Moreover, our findings do not support the supplementation of unsaturated fatty acids for cardiovascular disease prevention.

Antibiotic therapy is indicated during acute cholecystitis. However, in the treatment of uncomplicated cholelithiasis, prophylactic use of antibiotics is controversial. Microbiological and laboratory data are the basis for the choice of antibiotic treatment. However, monitoring and updating local antibiograms is important because they ensure effective therapy in the given clinical environment. The study included 110 consecutive patients who underwent laparoscopic cholecystectomy, divided into the group of uncomplicated cholelithiasis (n=60) and the group of acute cholecystitis (n=50). Preoperative data included age, sex, body mass index, leukocytes, C-reactive protein, and ultrasound examination. Bile samples for bacteriological testing were obtained under aseptic conditions during the surgery. Cultures were evaluated for aerobic, anaerobic and fungal organisms using routine tests. After the surgery, gallbladder specimens were sent for histopathological examination. In the group of uncomplicated cholelithiasis, 6/60 positive samples were found, and in the group of acute cholecystitis, there were 25/50 positive microbiological findings. Citrobacter sp. and Enterococcus faecalis predominated in the group of uncomplicated cholelithiasis, and Escherichia coli, Enterococcus faecalis, Proteus mirabilis and Citrobacter sp. in the group of acute cholecystitis. Antibiotics were administered to 49/50 patients with acute cholecystitis and to 32/60 patients with uncomplicated cholelithiasis. Cefazolin was the most frequently used antibiotic and also the most resistant antibiotic. To conclude, the administration of antibiotics in elective patients is not justified. The results of this study indicate that third-generation cephalosporin or ciprofloxacin + metronidazole should be administered in mild and moderate acute cholecystitis, and fourth-generation cephalosporin + metronidazole in severe acute cholecystitis in this local setting. The appropriate use of antibiotic agents is crucial and should be integrated into good clinical practice and standards of care.

BACKGROUND & AIMS: Gallstone disease (GD) is a major cause for consultation at general surgery services worldwide. In fact, GD has a strong relationship with environmental factors. However, specific characteristics in the Mexican population have not been established. The aim of this study was to compare the dietary components, physical activity, body composition and serum lipids in women with and without GD. METHODS: 54 women with GD and 75 without GD from West Mexico were enrolled in a cross-sectional study. Dietary intake was obtained through a habitual day food record and analyzed using the Nutritionist Pro™ software. Physical activity was evaluated in accordance with WHO recommendations. Body fat percentage (BF%) was estimated by bioimpedance (InBody 370) and serum lipids were measured using dry chemistry (Vitros-250 Analyzer). Student's t-test and binary logistic regression model were used. RESULTS: Women with GD presented a higher BF% (40 ± 8.7 vs 35.21 ± 9.8%, p = 0.004), an elevated dietary ω-6:ω-3 polyunsaturated fatty acids (PUFA) ratio (18.0 ± 11.4 vs 10.9 ± 4.7, p<0.001) and a higher simple carbohydrates (sCH) intake (28.3 ± 17.8 vs 13.23 ± 8.2%, p<0.001) as well as lower HDL-cholesterol levels (37.43 ± 8.5 vs 46.6 ± 12.02 mg/dL, p<0.001) compared with women without GD. Furthermore, it was foun d a higher ω-6:ω-3 PUFA ratio (OR: 3.9, 95% CI 1.52-10.38, p = 0.005) and excessive sCH consumption (OR: 7.4, 95% CI 1.92-28.65, p = 0.004). CONCLUSION: We suggest that a high dietary ω-6:ω-3 PUFA ratio and an excessive sCH intake are associated with an increased risk of GD in women.

BACKGROUND: Traditional Chinese medicine (TCM) may improve the prognosis management of cholelithiasis patients after gallbladder-preserving lithotripsy. To explore the evidence for this view, we systematically reviewed the efficacy and safety of TCM for improving the prognosis of cholelithiasis after gallbladder-preserving lithotripsy and performed functional pathway enrichment analysis of TCM target genes. METHODS: In this systematic review (SRs), we searched six Chinese or international databases to collect randomized controlled clinical trials (RCTs) of TCM in preventing the recurrence of cholelithiasis after gallbladder-preserving lithotripsy. The literature was independently screened by 2 reviewers, who then extracted the data. The Cochrane risk-of-bias and Grading of Recommendations, Assessment, Development and Evaluations (GRADE) tools were used to assess the included studies' risk of bias and quality of evidence, respectively. And, the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses would be conducted on the TCM prescriptions in the included literature to find the effective component and mechanism of TCM in the prognosis management of gallbladder-preserving lithotripsy. Analysis in this research would be conducted by R 3.5.2 software. RESULTS: A total of 1,024 articles were retrieved, and 9 RCTs involving 926 participants were included after the step-by-step screening. The risk of bias for each important outcome in all the studies was "uncertain". The meta-analysis showed that compared with blank control, TCM prevented cholelithiasis by decreasing the recurrence rate, complications incidence, gallbladder wall thickness, and gallbladder contraction degree. But, there were no significant differences in the rate of the adverse reaction. The result of the GO and KEGG analysis revealed that the mechanism of prevention of TCM in gallstone recurrence may be related to the cholesterol metabolic pathway and that naringin from Glycyrrhiza may be the effective component in the prevention of recurrence. CONCLUSIONS: Existing evidence suggests that the use of TCM may reduce the recurrence rate after gallbladder-preserving lithotripsy and this effect may be related to the flavonoid glycoside naringin from Glycyrrhiza uralensis, but more RCTs with high quality in this area may be needed to have a robust conclusion.

With the progression of acute cholecystitis, antimicrobial therapy becomes important for infection control. Current antibiotic recommendations were mostly based on reports of patients with acute cholangitis whose bile specimens were sampled from the biliary tract. However, as most infections of acute cholecystitis are limited to the gallbladder, direct sampling from the site increases the probability of identifying the causative pathogen. We investigated 321 positive bile cultures from 931 patients with acute cholecystitis who underwent laparoscopic cholecystectomy between January 2003 and December 2017. The frequency of enterococci declined (P = 0.041), whereas that of Enterobacteriales (P = 0.005), particularly Escherichia (P = 0.008), increased over time. The incidence of ciprofloxacin-resistant Enterobacteriales showed a significant increasing trend (P = 0.031). Vancomycin-resistant E.faecium, carbapenem-resistant Enterobacteriales, and extended-spectrum beta-lactamase-producing Enterobacteriales were recently observed. In grade I and II acute cholecystitis, there were no significant differences in perioperative outcomes in patients with and without early appropriate antimicrobial therapy. In conclusion, the changing incidence of frequently isolated microorganisms and their antibiotic resistance over time would be considered before selecting antibiotics for the treatment of acute cholecystitis. Surgery might be a crucial component of infection control in grade I and II acute cholecystitis.

Pyruvate kinase deficiency (PKD) is an autosomal-recessive enzyme defect of the glycolytic pathway that causes congenital nonspherocytic hemolytic anemia. The diagnosis and management of patients with PKD can be challenging due to difficulties in the diagnostic evaluation and the heterogeneity of clinical manifestations, ranging from fetal hydrops and symptomatic anemia requiring lifelong transfusions to fully compensated hemolysis. Current treatment approaches are supportive and include transfusions, splenectomy, and chelation. Complications, including iron overload, bilirubin gallstones, extramedullary hematopoiesis, pulmonary hypertension, and thrombosis, are related to the chronic hemolytic anemia and its current management and can occur at any age. Disease-modifying therapies in clinical development may decrease symptoms and findings associated with chronic hemolysis and avoid the complications associated with current treatment approaches. As these disease-directed therapies are approved for clinical use, clinicians will need to define the types of symptoms and findings that determine the optimal patients and timing for initiating these therapies. In this article, we highlight disease manifestations, monitoring approaches, strategies for managing complications, and novel therapies in development.

Cholesterol Gallstone Disease (GSD) is a common multifactorial disorder characterized by crystallization and aggregation of biliary cholesterol in the gallbladder. The global prevalence of GSD is ~10-20% in the adult population but rises to 28% in Chile (17% among men and 30% among women). The small intestine may play a role in GSD pathogenesis, but the molecular mechanisms have not been clarified. Our aim was to identify the role of the small intestine in GSD pathogenesis. Duodenal biopsy samples were obtained from patients with GSD and healthy volunteers. GSD status was defined by abdominal ultrasonography. We performed a transcriptome study in a discovery cohort using Illumina HiSeq. 2500, and qPCR, immunohistochemistry and immunofluorescence were used to validate differentially expressed genes among additional case-control cohorts. 548 differentially expressed genes between GSD and control subjects were identified. Enriched biological processes related to cellular response to zinc, and immune and antimicrobial responses were observed in GSD patients. We validated lower transcript levels of metallothionein, NPC1L1 and tight junction genes and higher transcript levels of genes involved in immune and antimicrobial pathways in GSD patients. Interestingly, serum zinc and phytosterol to cholesterol precursor ratios were lower in GSD patients. A significant association was observed between serum zinc and phytosterol levels. Our results support a model where proximal small intestine plays a key role in GSD pathogenesis. Zinc supplementation, modulation of proximal microbiota and/or intestinal barrier may be novel targets for strategies to prevent GSD.

OBJECTIVE: To determine the molecular characterization and disease-associated complications of beta-thalassemia intermedia (ß-TI) patients in Sulaymaniyah province, northeastern Iraq. METHODS: A total of 159 ß-TI) patients in Sulaymaniyah province, northeastern Iraq. ß-TI) patients in Sulaymaniyah province, northeastern Iraq. RESULTS: Nineteen different ß-globin gene mutations arranged in 37 various genotypes were determined. The most frequent were IVS-II-I (G>A) (47.2%), followed by IVS-I-6 (T>C) (23.3%) and IVS-I-110 (G>A) (5%). Among disease-related morbidities documented, bone disease amounted to 53% (facial deformity and osteoporosis), followed by endocrinopathies 17.6% (growth retardation and subclinical hypothyroidism), cholelithiasis 13.8%, pulmonary hypertension 11.3%, and abnormal liver function test 7.5%, whereas venous thrombosis, extramedullary hemopoiesis, and leg ulcer were less frequently observed. Age ≥ 35 and female sex were risk factors for cholelithiasis, while age was an independent risk for hypothyroidism and female sex was associated with increased risk for osteoporosis. Mean serum ferritin of ≥1000 µg/L was associated with an increased risk of osteoporosis, whereas chelation therapy was protective for a multitude of other complications. Transfusion, on the other hand, increased the risk of osteoporosis, yet it was protective for cholelithiasis and hypothyroidism. Moreover, splenectomy was protective for cholelithiasis, although it was an independent risk for hypothyroidism. Finally, hydroxyurea was associated with an increased risk of osteoporosis, while it was protective for cholelithiasis. Discussion and Conclusion. ß +-thalassemia mutation had contributed to 41.25 of families with a less severe ß-thalassemia phenotype in the northeastern part of Iraq, justifying the need to investigate the contribution of genetic modifiers in ameliorating disease severity. In addition, the substantial number of ß-TI patients developed disease-related morbidities, which necessitates the need for more appropriate clinical management with earlier intervention.ß-TI) patients in Sulaymaniyah province, northeastern Iraq. µg/L was associated with an increased risk of osteoporosis, whereas chelation therapy was protective for a multitude of other complications.

INTRODUCTION: Cholelithiasis and kidney stones are frequent pathologies in developed countries. Gallstones can be pigmentary, cholesterol (75%) or mixed. Age, female sex, obesity, rapid weight loss, consumption of refined sugars, saturated fat, iron deficiency, vitamin D and low intake of fiber and vitamin C are factors associated with an increased risk of cholelithiasis. On the other hand, the intake of ω-3 fatty acids, oleic acid, calcium, magnesium, fiber, fruits and vegetables, dairy products, nuts, coffee, moderate consumption of alcohol, vitamin C supplements, physical exercise and a regular diet have a protective paper. The most frequent kidney stones are calcium oxalate followed by mixed ones (oxalate and calcium phosphate), struvite, uric acid and cystine. A high water intake is recommended (> 2.5 l / day), varying the type of recommended or unadvisable food depending on the type of calculus. In oxalic lithiasis it is recommended to reduce the consumption of meat, moderate that of spinach, Swiss chard, asparagus, chocolate and avoid excessive sodium intake. The administration of oxalate-degrading probiotics (Lactobacillus) may reduce intestinal absorption, although further studies are necessary to corroborate these results. In calcium phosphate acidifying diet is recommended and limit the consumption of coffee and tea. The prevention of uric calculus is based on hydration with alkalizing drinks and vegetarian diet, decreasing foods rich in purines (liver, kidney, fish eggs, anchovies, sardines and seafood) and in calculus of cystine diet is recommended alkalizing. Since the formation of struvite calculi is due to urinary infections, pharmacological treatment and the consumption of acidifying diets, moderation of the intake of phosphate-rich foods and limiting the contribution of fats and citrus fruits are necessary. The nutritional intervention is an effective measure in the prevention of biliary and renal lithiasis and prevent its recurrence.
INTRODUCCIÓN: La colelitiasis y litiasis renal son patologías frecuentes en países desarrollados. Los cálculos biliares pueden ser pigmentarios, de colesterol (75%) o mixtos. La edad, el sexo femenino, la obesidad, la pérdida rápida de peso, el consumo de azúcares refinados, la grasa saturada, la deficiencia de hierro y de vitamina D y la baja ingesta de fibra y vitamina C son factores asociados a mayor riesgo de colelitiasis. Por otro lado, la ingesta de ácidos grasos ω-3, ácido oleico, calcio, magnesio, fibra, frutas y verduras, lácteos, frutos secos, café, un consumo moderado de alcohol, suplementos de vitamina C, ejercicio físico y una alimentación regular desempeñan un papel protector. Las litiasis renales más frecuentes son de oxalato cálcico, seguidas de las mixtas (oxalato y fosfato cálcico), estruvita, ácido úrico y cistina. Se aconseja una elevada ingesta hídrica (> 2,5 l/día), variando el tipo de alimentos recomendados o desaconsejados en función del tipo de cálculo. En litiasis oxálica se recomienda reducir el consumo de carne, moderar el de espinacas, acelgas, espárragos, chocolate y evitar el aporte excesivo de sodio. La administración de probióticos degradantes de oxalato (Lactobacillus) podría reducir su absorción intestinal, aunque son necesarios más estudios para corroborar estos resultados. En las de fosfato cálcico se aconseja dieta acidificante y limitar el consumo de café y té. La prevención de cálculos de úrico está basada en la hidratación con bebidas alcalinizantes y dieta vegetariana, disminuyendo los alimentos ricos en purinas (hígado, riñón, huevas de pescado, anchoas, sardinas y mariscos), y en cálculos de cistina se aconseja el consumo de dietas alcalinizantes. Dado que la formación de cálculos de estruvita se debe a infecciones urinarias, es necesario un tratamiento farmacológico y el consumo de dietas acidificantes, moderar la ingesta de alimentos ricos en fosfatos y limitar el aporte de grasas y cítricos. La intervención nutricional es una medida eficaz en la prevención de la litiasis biliar y renal y para evitar su recurrencia.

BACKGROUND: Transcylindrical cholecystectomy (TC) can be performed under local anaesthesia and sedation (LAS) in ambulatory surgery (AS). The aim of this study was to assess the feasibility and results of TC under LAS. METHODS: TC under LAS was proposed to 583 consecutive patients with cholelithiasis in an AS unit. For the TC procedure, a cylindrical retractor with a transparent plunger was inserted into the hepatocystic triangle, and cholecystectomy was performed through the retractor with reusable open instruments. Pre-, intra-, and post-operative variables were prospectively registered, including complications, reasons for conversion to general anaesthesia (GA), non-programmed admissions, readmissions, pain assessments, and satisfaction with the procedure. RESULTS: Five hundred patients were eligible for LAS, with GA being required in 128 (25.6%) of them. AS was programmed for 447 patients. The rates of non-programmed admissions, readmissions, and conversion to laparotomy were 8.7% (39), 0.8% (4), and 2.6% (13), respectively. There was no main bile duct injury. At 24 h, physical status was good or excellent in 80.4% of the patients. A history of acute cholecystitis, male sex, a body mass index (BMI) ≥ 39.5 kg/m2, and non-suspected acute cholecystitis were found to be independent variables associated with conversion to GA. CONCLUSIONS: TC under LAS is a safe procedure in AS and is feasible in 74% of cholelithiasis patients. Male sex, BMI, gallbladder wall thickness, and a history of acute cholecystitis are factors that increase the probability of conversion to GA. This prospective study was approved by the ethics committee of Badajoz for patient protection for biomedical research and has been retrospectively registered under the research registry UIN: researchregistry3979.

OBJECTIVE: Reducing adverse effects in laparoscopic cholecystectomy (LCE) is important to avoid complications. After removal, the porta hepatis and gallbladder bed of liver were treated with pulse width modulated (PWM) red LED light with parameters λ = 625 ± 5 nm, full width at half maximum 17 nm, 76 Hz, duty cycle 23%, 15-30 mW/cm2, and 0.9-1.8 J/cm2. The changes of eight blood parameters were studied: red blood cell, hemoglobin, white blood cell, erythrocyte sedimentation rate (ESR), bilirubin, aspartate transaminase (AST), alanine transaminase (ALT), and amylase. BACKGROUND DATA: Other current methods of reducing undesirable effects of LCE significantly affect surgery and are not commonly used in practice. MATERIALS AND METHODS: Before LCE, 263 patients were randomized into the control and test groups. Patients in the test group were treated with light radiated for 2 min during the surgery on the bed of the removed gallbladder and porta hepatis. Blood samples were taken before surgery and on the third day after surgery, studied, and compared by nonparametric statistical methods. RESULTS: The test group revealed significant reduction in postsurgery gain of levels of ALT, AST, and ESR compared with the control group. CONCLUSIONS: Treatment of the removed gallbladder bed and porta hepatis by red LED PWM radiation during LCE significantly reduces the adverse effects of surgery while increasing its time insignificantly and does not affect the surgical best practices deployed.

BACKGROUND: Various mechanisms, including somatic and visceral nociceptive stimulation, have been suggested as a cause for pain after laparoscopic cholecystectomy (LC). We therefore conducted a prospective randomized controlled trial (PRCT) to evaluate whether somatovisceral pain blockade reduces pain after LC. HYPOTHESIS: Analgesic efficacy of multimodal analgesia is superior to standard analgesia for patients undergoing elective LC for symptomatic cholelithiasis. Specifically, topical cystic plate and port-site injection with 0.25 % bupivacaine significantly reduces pain after LC. DESIGN: This study was designed as single-blinded PRCT. SETTING: This study was conducted in an academic medical center. PATIENTS AND METHODS: Between February and May 2010 we randomly assigned 63 patients with symptomatic cholelithiasis in a 1:1 ratio to non-opioid/opioid analgesic combinations (Control Group, n = 32) and non-opioid/opioid analgesic combinations plus topical 0.25 % bupivacaine onto the cystic plate and local 0.25 % bupivacaine port-site injection, post-LC (Study Group, n = 31). Primary endpoint was patient-reported pain 1, 4, 6, 12, 24 h and 1 week post-LC using the Visual Analog Scale (VAS 0-10). RESULTS: Study groups were comparable clinicopathologically. There were no adverse events. A statistically significant reduction in mean pain score was apparent in Study Group patients in comparison with Control Group (mean VAS 4.83 ± 2.33 vs. 6.80 ± 1.87; p < 0.001) at all early (1-6 h) post-operative time points following LC. CONCLUSION: This PRCT shows significantly improved pain control with somatovisceral pain blockade over non-opioid/opioid analgesic combinations following LC for symptomatic cholelithiasis. For centers not utilizing adjunctive local anesthetic for LC, this topical use of bupivacaine may improve patient comfort during recovery. This trial was registered on www.ClinicalTrials.gov NCT# 01972620.

Bariatric surgery is considered as the only effective durable weight-loss therapy and may be curative for obesity-related comorbidities such as diabetes. Nevertheless this surgery is not devoid of potential long-term complications such as dumping syndrome, gastroesophageal reflux disease and nutrient deficiencies. For this reason, preoperative nutritional assessment and rigorous postoperative follow-up with administration of multi-vitamins supplements and assessment of serum levels is recommended for each patient who is undergoing a bariatric surgery. The aim of this review is to identify and treat the metabolic and nutritional complications of bariatric surgery.

BACKGROUND: Laparoscopic cholecystectomy is the gold standard for gallstone disease. Postoperative pain still is considerable and may prevent early discharge. METHODS: A randomized controlled blind clinical trial was designed for all patients undergoing laparoscopic cholecystectomy. The groups were control (group A), preincisional trocar wound infiltration with bupivacaine (group B), and preincisional trocar wound infiltration and intraperitoneal instillation of bupivacaine over the gallbladder and liver surface before starting the dissection (group C). The operative technique and postoperative analgesia were standardized. The pain in 6 hours was assessed with the visual analog scale as the primary outcome. RESULTS: The visual analog pain scores in the intraperitoneal bupivacaine were similar to the trocar wound infiltration alone and both were lower than the control group (P=0.05616). CONCLUSIONS: Intraperitoneal application of local anesthetics and trocar wound infiltration did not lower the pain scores in comparison with trocar wound infiltration in our study.

ETNOPHARMACOLOGICAL RELEVANCE: Infusions of Herniaria hirsuta L., Herniaria glabra L. and Herniaria fontanesii J.Gay are well known in Moroccon folk medicine for the treatment of biliary dyskinesia, (uro)lithiasis or as a diuretic. Herniariae Herba which can contain H. glabra and H. hirsuta is known in Europe as an urological drug. AIM OF THE STUDY: To investigate the efficacy of a standardized infusion of Herniaria hirsuta against choleltihiasis, and evaluation of its genotoxicity. METHODS AND MATERIALS: An analytical HPLC-UV method to quantify flavonoids and saponins present in the extract of H. hirsuta was developed and validated. An in vivo experiment to evaluate the cholesterol lowering effect of a infusion of H. hirsuta in the gall bladder of dogs was carried out. Dogs were divided into 3 groups i.e. control dogs (CG), dogs treated with ursodeoxycholic acid (UDCA) (2×7.35mg/kg body weight/day) and dogs treated with the standardized infusion (HG) (2×48.5mg/kg body weight/day). Dogs were fed a fatty diet during 120 days after which a diet without additional fat was introduced till day 180. Treatment started 30 days after introduction of the fatty diet and lasted till the end of the experiment. A bile and blood sample of each dog was collected every 30 days, after which the concentration of cholesterol was determined. An Ames test was performed according to the OECD-guidelines. RESULTS: The validated HPLC-UV method showed a linear calibration model and an acceptable precision for the total flavonoid content (total content 4.51%) as well as the total saponin content (12.74%). The in vivo experiments already showed a minor difference for bile cholesterol between CG and HG after 30 days of treatment with the infusion, and the difference was more pronounced after 90 days of treatment. Even 30 days after discontinuation of the cholesterol-rich diet a significant difference remained between CG and HG. There was no statistically significant difference in blood cholesterol. The Ames test showed that the infusion of H. hirsuta could be considered as being free from genotoxic risks. CONCLUSION: A method for the standardization of a infusion of Herniaria hirsuta was developed and validated. Prolonged use of this standardized H. hirsuta extract resulted in a cholesterol-lowering effect in the bile of dogs. Since this pharmacological effect prevents the formation of gallstones and can contribute to solving existing gallstones, a standardized infusion of H. hirsuta may have a positive effect in the treatment of gallstones in human patients.

Danshu capsule (DSC) is a medicinal compound in traditional Chinese medicine (TCM). It is commonly used for the treatment of acute & chronic cholecystitis as well as choleithiasis. To study its choleretic effect, healthy rats were randomly divided into DSC high (DSCH, 900mg/kg), medium (DSCM, 450mg/kg), and low (DSCL, 225mg/kg) group, Xiaoyan Lidan tablet (XYLDT, 750mg/kg), and saline group. The bile was collected for 1h after 20-minute stabilization as the base level, and at 1h, 2h, 3h, and 4h after drug administration, respectively. Bile volume, total cholesterol, and total bile acid were measured at each time point. The results revealed that DSC significantly stimulated bile secretion, decreased total cholesterol level and increased total bile acid level. Therefore, it had choleretic effects. To identify the active components contributing to its choleretic effects, five major constituents which are menthol (39.33mg/kg), menthone (18.02mg/kg), isomenthone (8.18mg/kg), pluegone (3.31mg/kg), and limonene (4.39mg/kg) were tested on our rat model. The results showed that menthol and limonene could promote bile secretion when compared to DSC treatment (p > 0.05); Menthol, menthol and limonene could significantly decrease total cholesterol level (p<0.05 or p<0.01) as well as increase total bile acid level (p<0.05 or p<0.01); Isomenthone, as a isomer of menthone, existed slightly choleretic effects; Pluegone had no obvious role in bile acid efflux. These findings indicated that the choleretic effects of DSC may be attributed mainly to its three major constituents: menthol, menthone and limonene.
