Targeted bile acids metabolomics in cholesterol gallbladder polyps and gallstones: From analytical method development towards application to clinical samples

Bile acids (BAs) are synthesized by the liver from cholesterol through several complementary pathways and aberrant cholesterol metabolism plays pivotal roles in the pathogeneses of cholesterol gallbladder polyps (CGP) and cholesterol gallstones (CGS). To date, there is neither systematic study on BAs profile of CGP or CGS, nor the relationship between them. To explore the metabolomics profile of plasma BAs in healthy volunteers, CGP and CGS patients, an ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was developed and validated for simultaneous determination of 42 free and conjugated BAs in human plasma. The developed method was sensitive and reproducible to be applied for the quantification of BAs in the investigation of plasma samples. The results show that, compared to healthy volunteers, CGP and CGS were both characterized by the significant decrease in plasma BAs pool size, furthermore CGP and CGS shared aberrant BAs metabolic characteristics. Chenodeoxycholic acid, glycochenodeoxycholic acid, λ-muricholic acid, deoxycholic acid, and 7-ketolithocholic acid were shared potential markers of these two cholesterol gallbladder diseases. Subsequent analysis showed that clinical characteristics including cysteine, ornithine and body mass index might be closely related to metabolisms of certain BA modules. This work provides metabolomic information for the study of gallbladder diseases and analytical methodologies for clinical target analysis and efficacy evaluation related to BAs in medical institutions.

Microbiological analysis and predictors of gallbladder infection with antimicrobial susceptibility patterns in an HIV setting.

Background South Africa has a high prevalence of people living with human immunodeficiency virus (HIV; PLWH) who have shown to affect the prevalence and severity of infection and sepsis particularly gallbladder disease. Empirical Antimicrobial (EA) therapy for acute cholecystitis (AC) is based largely on bacteria colonisation of bile (bacteriobilia) and antimicrobial susceptibility patterns (antibiograms) obtained from the developed world where the prevalence of PLWH is very low. In an ever-emerging era of increasing antimicrobial resistance, monitoring and updating local antibiograms is underscored. Objective Due to the paucity of data available locally to guide treatment we found it pertinent to examine gallbladder bile for bacteriobilia and antibiograms in a setting with a high prevalence of PLWH to determine if this may demand a review of our local antimicrobial policies for gallbladder infections for both EA and pre-operative antimicrobial prophylaxis (PAP) for laparoscopic cholecystectomies (LC). Methodology A retrospective observational descriptive study was undertaken at King Edward VIII Hospital, Durban, KwaZulu-Natal, South Africa. Hospital records were reviewed for all patients undergoing cholecystectomy over a 3-year period. Gallbladder bacteriobilia and antibiograms were assessed and compared between PLWH and HIV uninfected (HIV-U). Pre-operative age, ERCP, PCT, CRP and NLR were used as predictors for bacteriobilia. Statistical analyses were performed using R Project and p values of less than 0.05 were considered as statistically significant. Results There were no differences in bacteriobilia or antibiograms between PLWH and HIV-U. There was >30% resistance to amoxicillin/clavulanate and cephalosporins. Aminoglycoside-based therapy, had good susceptibility patterns whilst carbapenem-based therapy demonstrated the lowest resistance levels. ERCP and age were predictors of bacteriobilia (p<0.001 and 0.002 respectively). PCT, CRP and NLR were not. Conclusion PLWH should follow the same PAP and EA recommendations as HIV-U. For EA, we recommend, a combination of amoxicillin/clavulanate with aminoglycoside-based therapy (amikacin or gentamycin) or piperacillin/tazobactam as monotherapy. Carbapenem-based therapy should be reserved for drug resistant species. For PAP, we recommend the routine use in older patients and patients with history of ERCP undergoing LC.

Extra-intestinal complications of Ascaris lumbricoides infections in India: A systematic review and meta-analysis.

The aberrant migration of Ascaris lumbricoides may cause extra-intestinal ascariasis (EIA) involving hepato-biliary-pancreatic (HBP) or other extra-gastro-intestinal (EGI) organs. We performed a systematic review and meta-analysis to study the risk factors and clinical presentations of EIA, and differences in HBP and EGI ascariasis. Medline, Web of Science and Embase were searched for cases of EIA in the English language from India. From 1204 articles, 86 studies (105 cases) were included. The majority of the cases involved the HBP system (78%). Among HBP ascariasis, the most commonly involved site was the bile duct (53.6%). Females had 11.3 times higher odds (95% CI 2.852 to 44.856; p=0.001) of HBP ascariasis, while the pediatric population had lower odds (OR=0.323). Previous gallbladder disease was significantly associated with HBP ascariasis in adults (p=0.046), while a significantly higher number of cases of EGI ascariasis were observed among pediatric patients (p=0.003). Ocular symptoms occurred exclusively in the pediatric population (p=0.017). Overall, death was reported in 3.8% of patients (n=4). This review emphasizes the importance of the complications of EIA. It encourages future research into issues such as the reasons of higher gall bladder ascariasis in females and the implications of Ascaris-related complications following biliary tract interventions. It also suggests considering Ascaris as a differential diagnosis for airway obstuction in intubated critically ill patients.

Initial experience of transpapillary gallbladder biopsy using newly designed device delivery system.

Transpapillary gallbladder biopsy has been reported for the diagnosis of gallbladder disease, and this procedure requires special biopsy forceps or a large-diameter pusher catheter. We retrospectively examined consecutive patients who underwent transpapillary gallbladder biopsy using a newly designed device delivery system (Endosheather; Piolax Medical Device, Kanagawa, Japan). We evaluated 11 patients (median age, 71 years [28-85]) who underwent transpapillary gallbladder biopsy from June 2021 to July 2022. The selective gallbladder cannulation and delivery system insertion success rate was 90.9% (10/11). The target lesion biopsy success rate was 63.6% (7/11). The biopsy time (i.e., time to completion of biopsy after successful guidewire placement) was 8.7 (5.4-32.7) min. In 1 patient in whom all 6 gallbladder bile juice cytology results were benign, the biopsy result was suspicious of adenocarcinoma. The final diagnosis for this patient was gallbladder cancer. Adverse events occurred in 2 patients. In 1 patient, acute cholecystitis occurred and required emergency surgery. Transpapillary gallbladder biopsy using the Endosheather is a potential option for the diagnosis of gallbladder disease. A good indication for this technique is considered to be wall thickening at the gallbladder fundus, where it is difficult to differentiate between benign and malignant lesions by imaging modalities such as ultrasonography or endoscopic ultrasound. The addition of transpapillary gallbladder biopsy may be advantageous when performing bile juice cytology using a nasogallbladder drainage tube for the diagnosis of gallbladder disease.

Indications and Complication of Laparoscopic Cholecystectomy at a Tertiary Care Setting in Sindh Province: A Cross Sectional Survey

Objective: The study was aimed to-evaluate the indications and-complications-of the laparoscopic cholecystectomy at a tertiary care setting in sindh province. Background: The-hepato-biliary-system is affected by a wide range of illnesses known as gall bladder diseases, each of which has a unique clinical presentation and degree of morbidity. The majority of adult populations in Western nations are affected by cholelithiasis, which affects 5% to 25% of the adult population. Initially, people from developing nations had little access to the advantages of laparoscopic cholecystectomy. Materials and Methods: A cross sectional study was carried out at the surgical dept Chandka Medical College Hospital Larkana for a period of 6 months in 2020 which included patients who went through laparoscopic cholecystectomy were included in the study, however, the patients having a history of previous abdominal surgery, hepatobiliary carcinoma , challenges ejection fraction, patients with coagulopathies and those reactive for HbsAg or HCV antibodies were excluded from the study. Results: The mean age of the subjects was 43.8± 9.67 years. There were 93.7% of study participants were females, 18.6% were diabetic and 26.5%) were hypertensive. 41.81% patients were aged between 30 to 40 years. The indications for the cholecystectomy included Symptomatic cholelithiasis for 148 (83.62%) cases, acute cholecystitis for 24(13.56%) cases and gall bladder polyp for 5 (2.82%) cases. There were 11 (6.21%) cases which needed to be converted to open cholecystectomy. Bile leaking was reported in 8 (4.52%) cases and injury to liver/intestine were reported for 3 (1.69%) cases. Conclusion: In a setting of a developing country, -laparoscopic-cholecystectomy-looks to be a safe and-effective treatment with few complications. Keywords: Laparoscopic cholecystectomy, Indications, Complications, cholelithiasis.

Can the parkland grading scale predict the difficulty of laparoscopic cholecystectomy? A new approach to validation

BackgroundThe Parkland Grading Scale (PGS) is an intraoperative grading scale to stratify gallbladder disease severity during laparoscopic cholecystectomy (LC). We evaluated the usefulness of the PGS in predicting the difficulty levels of LC procedures using a novel approach.MethodsA total of 261 patients diagnosed with cholelithiasis and cholecystitis who underwent LC were assessed. The PGS and the surgical difficulty grading system were used to evaluate surgical procedures by reviewing the operation videos. Clinical baseline characteristics and post-treatment outcomes were also recorded. Differences between the five PGS grades in terms of surgical difficulty scores were analyzed using the Jonckheere-Terpstra test. The relationship between PGS grades and surgical difficulty scores was assessed using Spearman’s Rank correlation. Finally, the linear trends between morbidity scores and PGS grades were evaluated using the Mantel-Haenszel test.ResultsThere was a significant difference in the surgical difficulty scores for the five PGS grades (p < 0.001). In pairwise comparison, each grade (1–5) was significantly different from the others (p < 0.05) in terms of surgical difficulty, except Grade 2 vs. 3 (p = 0.07) and Grade 3 vs. 4 (p = 0.08). There was a significant correlation between PGS grades and surgical difficulty scores (rs = 0.681, p < 0.001). There was also a significant linear association between morbidity and PGS grades (p < 0.001). Spearman’s R value was 0.176 (p = 0.004).ConclusionThe PGS can accurately assess the surgical difficulty level of LC. The precision and conciseness of the PGS make it suitable for use in future research.

Detection of Gallbladder Disease Types Using Deep Learning: An Informative Medical Method.

Nowadays, despite all the conducted research and the provided efforts in advancing the healthcare sector, there is a strong need to rapidly and efficiently diagnose various diseases. The complexity of some disease mechanisms on one side and the dramatic life-saving potential on the other side raise big challenges for the development of tools for the early detection and diagnosis of diseases. Deep learning (DL), an area of artificial intelligence (AI), can be an informative medical tomography method that can aid in the early diagnosis of gallbladder (GB) disease based on ultrasound images (UI). Many researchers considered the classification of only one disease of the GB. In this work, we successfully managed to apply a deep neural network (DNN)-based classification model to a rich built database in order to detect nine diseases at once and to determine the type of disease using UI. In the first step, we built a balanced database composed of 10,692 UI of the GB organ from 1782 patients. These images were carefully collected from three hospitals over roughly three years and then classified by professionals. In the second step, we preprocessed and enhanced the dataset images in order to achieve the segmentation step. Finally, we applied and then compared four DNN models to analyze and classify these images in order to detect nine GB disease types. All the models produced good results in detecting GB diseases; the best was the MobileNet model, with an accuracy of 98.35%.

Evaluation of gallbladder motility assessed by ultrasonography in dogs with hyperlipidemia.

The pathogenesis of gallbladder (GB) mucoceles in dogs is unknown. It has been proposed that hyperlipidemia could impair GB motility and contribute to GB mucocele formation. The objective of this study was to compare GB motility in dogs with hyperlipidemia to control dogs using ultrasonography. We hypothesized that hyperlipidemic dogs will have decreased GB motility compared with controls. Twenty-six hyperlipidemic and 28 healthy, age-matched control dogs were prospectively enrolled. Cholesterol and triglyceride concentrations were measured in all dogs. Hyperlipidemia was defined as hypercholesterolemia (>332 mg/dL) and/or hypertriglyceridemia (>143 mg/dL) using a biochemical analyzer. Ultrasound was performed before feeding, and 60 and 120 minutes after ingestion of a high fat diet. Gallbladder volumes (GBV) and ejection fractions (EF) were calculated. Hyperlipidemic dogs had significantly larger GBVs (ml/kg) before feeding and 60 minutes after feeding of 1.2 (0.4-7.5; P = .008) and 0.6 (0.1-7.2; P = .04) compared with controls 0.6 (0.2-2.6) and 0.4 (0.1-1.9), respectively. Severely hyperlipidemic dogs had significantly larger GBV at baseline, 60 minutes, and 120 minutes of 1.7 (0.6-7.5; P = .03), 1.3 (0.4-7.2; P = .02), and 1.3 (0.2-8.2; P = .04), respectively compared with mildly hyperlipidemic dogs. EFs at 60 and 120 minutes between controls, hyperlipidemic, and severely hyperlipidemic were all 0.3 at 60 minutes and 0.5, 0.3, and 0.3 at 120 minutes, respectively which were not statistically different. Hyperlipidemia leads to GB distention in dogs which could lead to retention of bile and gallbladder disease.

Acute gallbladder disease – The virtue of performing a laparoscopic cholecystectomy in the early stages of case management

Background: In a Benghazi medical center, this observational study assessed the role of laparoscopic cholecystectomy (LC) in the early stages of acute gallbladder illness. Materials and Methods: From January 2022 to December 2022, all emergency and urgent admissions for acute gallbladder disease were identified, and additionally, data from hospital medical records were then evaluated retrospectively. Results: Out of a total of 334 patients with gallstone diseases, we found 321 individuals (206 with acute biliary colic, 115 with acute calculous cholecystitis), and 13 with acalculous cholecystitis. Early laparoscopic surgery for acute calculous cholecystitis had a greater conversion rate than procedures for acute biliary discomfort (19% vs. 4%; p=0.002). When surgery was performed 72 h from the onset of the symptoms for patients with acute calculous cholecystitis, the conversion rate was considerably lower (one out of 25) than when surgery was postponed past 72 h (14 out of 53) or later performed electively (seven out of 23) (p=0.014). In comparison to elective surgery for acute biliary colic (three of 66), elective surgery for prior acute cholecystitis was linked to a higher conversion rate (seven of 22 patients) (p=0.002). Conclusion: LC for acute calculous cholecystitis needs to be done within 72 h of the onset of symptoms, and it is worthwhile.

Prevalence of Symptomatic Gallbladder Disease After Bariatric Surgery: A Literature Review.

Introduction Gallbladder disease (GBD) encompasses several medical conditions, including gallbladder stone formation, biliary colic, and cholecystitis. These conditions may arise following bariatric surgery, including bypass or laparoscopic sleeve gastrectomy (LSG). The development of GBD after surgery may be attributed to various factors, including the formation of stones shortly after the procedure, the exacerbation of existing stones due to the surgery, or inflammation of the gallbladder. Rapid weight loss after surgery has also been proposed as a contributing factor. Methodology This observational study consisted of a review of retrospective hospital patient medical records of 350 adult participants who underwent LSG, with 177 participants included in the study after excluding those with cholecystectomy or GBD prior to surgery. The participants were followed for a median of two years, during which we recorded any hospitalizations, emergency department visits, clinic visits, and incidents of cholecystectomy or abdominal pain due to GBD. The participants were grouped into two: those with GBD and those without GBD after bariatric surgery, and quantitative data were summarized using mean and standard deviations. The data were analyzed using IBM SPSS Statistics for Windows, Version 20.0. (IBM Corp. Released 2020. IBM SPSS Statistics for Windows, Version 27.0. Armonk, NY: IBM Corp), with a statistical significance of P<0.05. Results In our retrospective study of 177 patients who underwent LSG, the incidence of GBD after bariatric surgery was 4.5%. Most patients with GBD after bariatric surgery were White, but this difference was not statistically significant. Patients with type 2 diabetes had a higher incidence of GBD after bariatric surgery than those without diabetes (8.3% vs. 3.6%, P=0.355). Patients with HTN had a lower incidence of GBD after bariatric surgery than those without HTN (1.1% vs. 8.2%, P=0.032). Anti-hyperglycemia medication use did not significantly increase the risk of GBD after bariatric surgery (7.5% vs. 3.8%, P=0.389). None of the patients on weight loss medication developed GBD after bariatric surgery, compared to 5% of patients who did not take weight loss medication. Our sub-data analysis showed that patients who developed GBD after bariatric surgery had a high BMI (above 40 kg/m2) before surgery, which decreased to 35 kg/m2 and below 30 kg/m2 at six months and 12 months post-surgery, respectively. Conclusions Our findings demonstrate that the prevalence of GBD after LSG is low and comparable to the general population without LSG. Thus, LSG does not increase the risk of GBD. We found that rapid weight loss after LSG is a significant risk factor for GBD. These findings suggest that patients who undergo LSG should be informed of the risks of GBD and undergo careful screening before surgery to detect any pre-existing gallbladder issues. Overall, our study highlights the importance of continued research into the factors associated with GBD after bariatric surgery and the need for standardized prophylactic measures to prevent this potentially serious complication.

Indocyanine green fluorescent cholangiography improves the clinical effects of difficult laparoscopic cholecystectomy.

Near-infrared fluorescent cholangiography (NIRFC) with indocyanine green (ICG) as the developer yields clear visualization of the extrahepatic bile ducts and is effective in identifying key structures. Here, we analyzed and compared the surgical outcomes of fluorescent and conventional laparoscopy in cholecystectomy of various difficulties and then assessed the value of NIRFC. This retrospective study collected clinical data from partial patients who underwent laparoscopic cholecystectomy (LC) at the Department of Hepatobiliary and Pancreatic Surgery, Zhongnan Hospital of Wuhan University between 2020 and 2021. The study subjects were classified into ICG-assisted and white-light laparoscopy. Two cohorts with homogeneous baseline status were selected based on 1:1 ratio propensity score matching (PSM). Multivariate logistic regression analysis was performed to predict independent risk factors for LC difficulty. Thereafter, the matched cases were classified into difficult and easy subgroups by combining difficulty score and gallbladder disease type, and then the surgical outcomes of the two groups were compared. This study included a total of 624 patients. The patients were classified into the ICG group (n = 218) and the non-ICG group (n = 218) after a 1:1 ratio PSM. Our data showed significant differences between the groups in operative time (P = 0.020), blood loss (P = 0.016), length of stay (P = 0.036), and adverse reaction (P = 0.023). Stratified analysis demonstrated that ICG did not significantly improve the surgical outcomes in simple cases (n = 208). On the other hand, in difficult cases (n = 228), NIRFC shortened operative time (P = 0.003) and length of stay (P = 0.015), reduced blood loss (P = 0.028) and drain placement rate (P = 0.015), and had fewer adverse reactions (P = 0.023). The data showed that five cases were converted to laparotomy while two cases had minor bile leaks in the non-ICG group. There was no bile duct injury (BDI) in all the cases. Furthermore, high BMI, history of urgent admission and abdominal surgery, palpable gallbladder, thickened wall, and pericholecystic collection were risk factors for surgical difficulty. ICG-assisted NIRFC provides real-time biliary visualization. In complicated conditions such as acute severe inflammation, dense adhesions, and biliary variants, the navigating ability of fluorescence can enhance the operation progress, reduce the possibility of conversion or serious complications, and improve the efficiency and safety of difficult LC.

Tirzepatide (Mounjaro) - a novel Pharmacotherapeutic Agent for Obesity.

Obesity and its consequential morbidities are a major global burden. with Pakistan having a national obesity risk of 6.5/10.(1) Raised BMI (body mass index-an index of weight to height ratio) along with obesity is one the prime risk factors that lead to numerous other non-transmissible diseases like heart diseases, Type 2 diabetes, osteoarthritis and certain carcinomas (Breast, ovarian, colon, liver, prostate, gall bladder). Lifestyle interventions can only produce modest (~5-10%) weight loss, necessitating other antiobesity interventions. Therefore, pharmacological approaches to losing weight are in the limelight. The U.S. (FDA) Food and Drug Administration has also authorized pharmacological treatment as a new treatment option to incorporate into weight management programme with concomitant dietary and physical behavioral remodeling in patients having 27 kg/m2 or higher BMI along with incidence of any of the following obesity-related comorbidities: T2DM, hypertension, or hypercholesterolemia (2).As of 2021 around 5 antiobesity medications (AOMs) have been approved by FDA so far but a recent randomized, placebo controlled double blind trial has incredibly unveiled the potential effects of tirzepatide as an antiobesity drug. Tirzepatide (Mounjaro) is an exclusive and the only dual receptor agonist the mimicking actions of glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) and therefore referred as “twincretin”. This drug, originally used to treat T2DM, has now been incredibly effective in treating obesity. According to a recent randomized control trial, 85% of participants with a 5.0 mg dose, 89% participants with a 10 mg dose and 91% participants with a 15 mg dose showed a significant reduction in weight(3) which is a corroborating evidence supporting tirzepatide as antiobesity drug. According to SURPASS-2 clinical trial, comparing efficacy of tirzepatide to semaglutide (a selective GLP-1 receptor agonist), tirzepatide was proven to reduce body weight and A1C levels more effectively than semaglutide demonstrating it to be better in treating not only diabetes but obesity(4). The SURMOUNT-1 trial, depicting the efficacy of tirzepatide, showed significant weight reduction of up to 22.5 % in obese adults (5) Some of the adverse effects noted with its use were gastrointestinal events like nausea, vomiting and diarrhea. A few contraindications are gallbladder disease, pancreatitis, genetic predisposition of medullary thyroid carcinoma and MEN (multiple endocrine neoplasia) Type 2. ---Continue

Parental Obesity: The Pandemic of Intergenerational Physical and Mental Health Carnage

A review of the maternal and paternal impact of obesity at conception on the subsequent health of the offspring paints a nightmarish future in terms of suffering and out-of-control healthcare spending. Consequences of parental obesity on the offspring include obesity, type 2 diabetes, cardiovascular disease, chronic kidney disease, stroke, and premature death. Children of obese women tend to have high blood pressure, left ventricular thickening, increased abdominal fat mass, hyperlipidemia with reduced high-density lipoprotein levels, increased aortic root diameter, insulin resistance, and elevated inflammatory markers, which culminate in a threefold greater risk of cardiometabolic complications than in children of normal-weight mothers. Babies are at greater risk of developing asthma, autism spectrum disorder, attention deficit hyperactivity disorder, cognitive delays, inflammation, cerebral palsy, epilepsy, and the chronic diseases of obesity (such as insulin resistance, high blood pressure, atherosclerosis, cardiovascular disease, stroke, some cancers, including breast, endometrial, and colon cancer, gall bladder disease, polycystic ovarian syndrome, musculoskeletal problems such as osteoarthritis and back pain, gout, cataracts, stress incontinence, and sleep apnea), as well as psychiatric disorders including substance abuse. All parents desire healthy babies, as does society, to avoid the health costs and consequences of our obesity pandemic, but significant personal, societal, public policy, economic, and marketplace interventions will be necessary to avert further devastating impacts. We need to publicize the intergenerational harm caused by obesity, offer support to individuals to help change eating habits and produce a healthier food chain for the nation. Interventions fashioned after the twelve-step program of Alcoholics Anonymous and the adoption of a low carbohydrate abstinence model have proven effective. The time has come to spread the research findings concerning obesity and intergenerational obesity. that are long-accepted by the scientific community but still not recognized by the public at large so that another generation is not impacted by lifestyles that have continuously worsened since the 1970s.

Associations of cholecystectomy with the risk of colorectal cancer: a Mendelian randomization study.

Cholecystectomy is a standard surgery for patients suffering from gallbladder diseases, while the causal effects of cholecystectomy on colorectal cancer (CRC) and other complications are still unknown. We obtained genetic variants associated with cholecystectomy at a genome-wide significant level ( P value <5 × 10 -8 ) as instrumental variables (IVs) and performed Mendelian randomization (MR) to identify the complications of cholecystectomy. Furthermore, the cholelithiasis was also treated as the exposure to compare its causal effects to those of cholecystectomy, and multivariable MR analysis was carried out to judge whether the effect of cholecystectomy was independent of cholelithiasis. The study was reported based on Strengthening the Reporting of Observational Studies in Epidemiology Using Mendelian Randomization guidelines. The selected IVs explained 1.76% variance of cholecystectomy. Our MR analysis suggested that cholecystectomy cannot elevate the risk of CRC (odds ratio [OR] =1.543, 95% confidence interval [CI]: 0.607-3.924). Also, it was not significant in either colon or rectum cancer. Intriguingly, cholecystectomy might decrease the risk of Crohn's disease (OR = 0.078, 95% CI: 0.016-0.368) and coronary heart disease (OR = 0.352, 95% CI: 0.164-0.756). However, it might increase the risk of irritable bowel syndrome (IBS) (OR = 7.573, 95% CI: 1.096-52.318). Cholelithiasis could increase the risk of CRC in the largest population (OR = 1.041, 95% CI: 1.010-1.073). The multivariable MR analysis suggested that genetic liability to cholelithiasis could increase the risk of CRC in the largest population (OR = 1.061, 95% CI: 1.002-1.125) after adjustment of cholecystectomy. The study indicated that cholecystectomy might not increase the risk of CRC, but such a conclusion needs further proving by clinical equivalence. Additionally, it might increase the risk of IBS, which should be paid attention to in clinical practice.

The Accuracy of Point-of-Care Ultrasound (POCUS) in Acute Gallbladder Disease.

There is increasing recognition that point-of-care ultrasound (POCUS), performed by the clinician at the bedside, can be a natural extension of the clinical examination-the modern abdominal "stethoscope" and provides an opportunity to expedite the care pathway for patients with acute gallbladder disease. The primary aims of this study were to benchmark the accuracy of surgeon-performed POCUS in suspected acute gallbladder disease against standard radiology or pathology reports and to compare time to POCUS diagnosis with time to definitive imaging. This prospective single-arm observational cohort study was conducted in four hospitals in Ireland, Italy, and Portugal to assess the accuracy of POCUS against standard radiology in patients with suspected acute biliary disease (ClinicalTrials.govIdentifier: NCT02682368). The findings of surgeon-performed POCUS were compared with those on definitive imaging or surgery. Of 100 patients recruited, 89 were suitable for comparative analysis, comparing POCUS with radiological findings in 84 patients and with surgical/histological findings in five. The overall global accuracy of POCUS was 88.7% (95% CI, 80.3-94.4%), with a sensitivity of 94.7% (95% CI, 85.3-98.9%), a specificity of 78.1% (95% CI, 60.03-90.7%), a positive likelihood ratio (LR+) of 4.33 and negative likelihood ratio (LR) of 0.07. The mean time from POCUS to the final radiological report was 11.9 h (range 0.06-54.9). In five patients admitted directly to surgery, the mean time between POCUS and incision was 2.30 h (range 1.5-5), which was significantly shorter than the mean time to formal radiology report. Sixteen patients were discharged from the emergency department, of whom nine did not need follow-up. Our study is one of the very few to demonstrate a high concordance between surgeon-performed POCUS of patients without a priori radiologic diagnosis of gallstone disease and shows that the expedited diagnosis afforded by POCUS can be reliably leveraged to deliver earlier definitive care for patients with acute gallbladder pathology, as the general surgeon skilled in POCUS is uniquely positioned to integrate it into their bedside assessment.

Rapid detection of serological biomarkers in gallbladder carcinoma using fourier transform infrared spectroscopy combined with machine learning

Gallbladder cancer (GBC) is the most common malignant tumour of the biliary tract. GBC is difficult to diagnose and treat at an early stage because of the lack of effective serum markers and typical symptoms, resulting in low survival rates. This study aimed to investigate the applicability of dried serum Fourier-transform infrared (FTIR) spectroscopy combined with machine learning algorithms to correctly differentiate patients with GBC from patients with gallbladder disease (GBD), cholangiocarcinoma (CCA), hepatocellular carcinoma (HCC) and healthy individuals. The differentiation between healthy individuals and GBC serum was better using principal component analysis (PCA) and linear discriminant analysis (LDA) for six spectral regions, especially in the protein (1710-1475 cm−1) and combined (1710–1475 + 1354-980 cm−1) region. However, the PCA-LDA model poorly differentiated GBC from GBD, CCA, and HCC in serum spectra. We evaluated the PCA- LDA, PCA-support vector machine (SVM), and radial basis kernel function support vector machine (RBF-SVM) models for GBC diagnosis and found that the RBF-SVM model performed the best, with 88.24–95% accuracy, 95.83% sensitivity, and 78.38–94.44% specificity in the 1710–1475 + 1354-980 cm−1 region. This study demonstrated that serum FTIR spectroscopy combined with the RBF-SVM algorithm has great clinical potential for GBC screening.

Gallstone Ileus: A Case Report in a 74-Year-Old Male.

Gallstone ileus is a rare complication of complicated gallbladder disease. Typically the result of a cholecystocholeduodenal fistula, a gallstone enters the small bowel and impacts in the ileum causing an obstruction. In this case study, a 74-year-old male presented to the emergency department with nausea, vomiting, and constipation for 2 weeks. CT revealed pneumobilia and a 3.1 cm calcified mass in the terminal ileum. The patient was successfully treated with a robotic-assisted enterotomy alone without complications.

Management of complex acute biliary disease for the general surgeon: A narrative review

Acute gallbladder diseases are a common surgical emergency faced by General Surgeons that can sometimes be quite challenging. These complex biliary diseases require multifaceted and expeditious care, optimized based on hospital facility and operating room (OR) resources and the expertise of the surgical team. Effective management of biliary emergencies requires two foundational principles: achieving source control while mitigating the risk of injury to the biliary tree and its blood supply. This review article highlights salient literature on seven complex biliary diseases: acute cholecystitis, cholangitis, Mirizzi syndrome, gallstone ileus with cholecystoenteric fistula, gallstone pancreatitis, gall bladder cancer, and post-cholecystectomy bile leak.

Association of adiposity with morbidity in Finnish adults: A register-based follow-up study.

The aims of this study were to update risk estimates of obesity related co-morbidities and to provide evidence of the importance of obesity prevention to decision makers. The study included 25- to 74-year-old participants (N=22,977) of the National FINRISK Studies in 1997, 2002 and 2007. Body mass index was calculated from measured weight and height at baseline. Data on morbidity were ascertained via linkage to the National Hospital Discharge Register, the Cancer Register and the records of the Social Insurance Institution of Finland until the end of year 2018. The Cox proportional hazards model was used to estimate associations between weight status and the risk of the end-point diseases during follow-up, with adjustment for age and smoking. At baseline, 31% of participants had at least one of the investigated diseases. Overweight, obesity and severe obesity were associated with type 2 diabetes, gout, gallbladder diseases and knee and hip osteoarthritis during the follow-up in both men and women. The risk of coronary heart disease was increased in men who were overweight, obese and severely obese and in women who were obese and severely obese. Risk of asthma was increased only among women who were obese and severely obese. No associations were found between obesity and breast, prostate or colorectal cancer. The study showed a strong relationship between excess body weight and the prevalence and incidence of several diseases. Obesity prevention is essential to reduce disease burden in the future.
