Different types and numbers metabolic abnormalities and risk of gallbladder stone disease in adults.

Background: Metabolic abnormalities in the body increase the risk of gallbladder stones and their complications, which brings a great economic and social burden. The relationship between different types and amounts of metabolic abnormalities and gallstone risk in different sexes is poorly documented and controversial. Methods: Based on the baseline survey data of the Chinese Multi-Ethnic Cohort (CMEC) study, 4,075 Chinese adults aged 30-79 years with complete abdominal ultrasound results and metabolic index data. Logistic regression model was used to evaluate the correlation between five metabolic abnormalities and gallstones, and to explore the gender difference. Results: The detection rate of gallbladder stones was found to be 7.0%, with a higher rate in women (8.6%) than in men (4.1%). Logistic results showed adjustment odds ratio (ORs) and 95% confidence interval (95% CI) of dysglycemia + hypertension + central obesity in 3 metabolic combinations was 4.459 (1.653, 12.029). The four metabolic combinations, dysglycemia + dyslipidemia + hypertension + central obesity, dysglycemia + dyslipidemia + hypertension + abnormal blood uric acid and dysglycemia + dyslipidemia + central obesity + abnormal blood uric acid adjusted OR and 95%CI were 3.342 (1.459, 7.659), 5.439 (1.555, 19.018) and 2.971 (1.187, 7.435), respectively. Gender-stratified analysis found that "any three or more metabolic abnormalities and their components were associated with gallstone risk, more significantly in women. Conclusion: Different types and amounts of five metabolic abnormalities were associated with the risk of gallstone development, and the differences were more significant in women than men.

Acute Calculous Cholecystitis Associated with Leptospirosis: Which is the Emergency? A Case Report and Literature Review.

Introduction: Leptospirosis is a bacterium with a worldwide distribution and belongs to the group of zoonoses that can affect both humans and animals. Most cases of leptospirosis present as a mild, anicteric infection. However, a small percentage of cases develop Weil's disease, characterized by bleeding and elevated levels of bilirubin and liver enzymes. It can also cause inflammation of the gallbladder. Acute acalculous cholecystitis has been described as a manifestation of leptospirosis in a small percentage of cases; however, no association between leptospirosis and acute acalculous cholecystitis has been found in the literature. Case presentation: In this report, we describe the case of a 66-year-old patient who presented to the emergency department with a clinical picture dominated by fever, an altered general condition, abdominal pain in the right hypochondrium, nausea, and repeated vomiting. Acute calculous cholecystitis was diagnosed based on clinical, laboratory, and imaging findings. During preoperative preparation, the patient exhibited signs of liver and renal failure with severe coagulation disorders. Obstructive jaundice was excluded after performing an abdominal ultrasound and computed tomography scan. The suspicion of leptospirosis was then raised, and appropriate treatment for the infection was initiated. The acute cholecystitis symptoms went into remission, and the patient had a favorable outcome. Surgery was postponed until the infection was treated entirely, and a re-evaluation of the patient's condition was conducted six-week later. Conclusions: The icterohemorrhagic form of leptospirosis, Weil's disease, can mimic acute cholecystitis, including the form with gallstones. Therefore, to ensure an accurate diagnosis, leptospirosis should be suspected if the patient has risk factors. However, the order of treatments is not strictly established and will depend on the clinical picture and the patient's prognosis.

Comparison of Endoscopic Ultrasound and Transabdominal Ultrasound in the Detection of Gallbladder and Common Bile Duct Microlithiasis.

OBJECTIVE: Endoscopic ultrasonography (EUS) is an emerging method with a wide range of potential uses in gastroenterology, including the detection of bile duct stones and the identification of early ductal alterations in suspected patients. This study was designed to compare the diagnostic yield of EUS and transabdominal ultrasound (TUS) in the detection of gallbladder and common bile duct (CBD) microlithiasis. METHOD: Patients with biliary colic with normal initial TUS were the subjects of this prospective study. EUS scan was performed on all recruited patients and linear endoscopes were used for the EUS examination. Cholecystectomy and histological analysis were done in patients within two weeks after EUS revealing cholelithiasis whereas the cases of CBD stone/microlithiasis were confirmed by endoscopic retrograde cholangiopancreatography (ERCP). The mean values of all hematological characteristics were independently determined for males and females and then compared using Student's t-test. For statistical significance, a p-value of 0.05 or below was used. RESULTS: A total of 131 patients, including 77 females and 54 males, with a mean age of 38.41 ± 14.78 years were examined. All 78 (59.5%) individuals who had cholecystectomy were found to have gallstones or microlithiasis as successfully diagnosed by EUS. The sensitivity and specificity of EUS were 92.9% and 100%, respectively, for CBD stones and 98.8% and 100%, respectively, for the detection of gallbladder microlithiasis. The agreement between EUS and TUS was fair for CBD stones (κ = 0.214) and very weak for microlithiasis (κ = -0.093). CONCLUSION: EUS demonstrates a superior yield over TUS in detecting gallbladder stones and CBD microlithiasis, offering a more reliable diagnostic modality. LIMITATION: This was a single-center study.

Correlation Between Hypothyroidism and Gallstone Disease in Central India.

Introduction The decreased thyroid-stimulating hormone (TSH) levels affect almost every nucleated cell in our body, which directly affects the basal metabolic rate (BMR). It tends to affect multiple organ systems in the human body. In recent times, there have been changes in lifestyle and the consumption of processed foods has increased. Thus, cholelithiasis and hypothyroidism are being encountered frequently, even in rural populations. In recent times, the overt clinical presentation of hypothyroidism is rare due to early diagnosis and treatment of the subclinical hypothyroidism state itself. Aim The aim is to determine the correlation between cholelithiasis and hypothyroidism. Methods This was a cross-sectional study done on the patients presenting to the surgical department at Acharya Vinoba Bhave Rural Hospital affiliated to Jawaharlal Nehru Medical College, Sawangi (Meghe), Wardha, Maharashtra, India between the duration from December 2020 to December 2022, having gallstone disease or with symptoms suggestive of gall bladder stones. The admitted patients were then evaluated for hypothyroidism by thyroid profile tests, and the results were documented. Using the collected data, factors such as clinical spectrum, correlation between cholelithiasis and hypothyroidism, relation with the demographic data, and body mass index (BMI) were studied. Results A total of 52 gallstone patients were included in the study. A greater number of patients were found to be above the age of 40 years (82.7%), with female preponderance (61.5%). More patients with cholelithiasis were from the group with having BMI more than normal (57.6%). More patients having both cholelithiasis and hypothyroidism were also from the group with having BMI more than normal. Most symptomatic patients complained of pain in the right hypochondriac region (88.5%). Of these 52 patients, nine (17.3%) were found to have hypothyroidism (seven were subclinical, two patients had overt clinical symptoms and signs) and the remaining 43 patients were euthyroid. Conclusions Our study supports that there is a correlation between cholelithiasis and hypothyroidism. Out of all the 52 patients, nine had hypothyroidism, seven were subclinical, and two had overt symptoms. Thus, we conclude that there is a correlation between cholelithiasis and hypothyroidism.

Application of Data Mining Technology in the Screening for Gallbladder Stones: A Cross-Sectional Retrospective Study of Chinese Adults.

PURPOSE: The purpose of this study was to use data mining methods to establish a simple and reliable predictive model based on the risk factors related to gallbladder stones (GS) to assist in their diagnosis and reduce medical costs. MATERIALS AND METHODS: This was a retrospective cross-sectional study. A total of 4215 participants underwent annual health examinations between January 2019 and December 2019 at the Physical Examination Center of Shengjing Hospital Affiliated to China Medical University. After rigorous data screening, the records of 2105 medical examiners were included for the construction of J48, multilayer perceptron (MLP), Bayes Net, and Naïve Bayes algorithms. A ten-fold cross-validation method was used to verify the recognition model and determine the best classification algorithm for GS. RESULTS: The performance of these models was evaluated using metrics of accuracy, precision, recall, F-measure, and area under the receiver operating characteristic curve. Comparison of the F-measure for each algorithm revealed that the F-measure values for MLP and J48 (0.867 and 0.858, respectively) were not statistically significantly different (p>0.05), although they were significantly higher than the F-measure values for Bayes Net and Naïve Bayes (0.824 and 0.831, respectively; p<0.05). CONCLUSION: The results of this study showed that MLP and J48 algorithms are effective at screening individuals for the risk of GS. The key attributes of data mining can further promote the prevention of GS through targeted community intervention, improve the outcome of GS, and reduce the burden on the medical system.

Negative gallbladder stones: Diagnostic advantages of dual-energy CT and analysis of a unique case.

BACKGROUND: Gallbladder stones are a common digestive system disease, but their diagnosis can be limited in some cases, especially in identifying "negative" stones, which may be difficult to recognize with traditional CT scans. OBJECTIVE: This study aims to explore the advantages of dual-energy CT in diagnosing negative gallbladder stones through a unique case of gallbladder stones. METHODS AND RESULTS: A case of a 31-year-old female is described, who was diagnosed with gallbladder stones during a physical examination two years ago and occasionally experienced pain in the upper right abdomen. Dual-energy CT scanning revealed a mixed-density stone, approximately 2 cm in diameter, in the neck of the gallbladder, consisting of a calcified shell (positive stone) and a homogenous density nucleus (negative stone). Verified by dual-energy CT, single-energy images and spectral curves can very intuitively identify negative stones, demonstrating significantly superior performance compared to traditional CT. CONCLUSION: Dual-energy CT, through single-energy images and spectral curves, intuitively identifies negative gallbladder stones, showcasing significant advantages compared to traditional CT, and offers a valuable approach to enhancing the diagnostic accuracy of gallbladder stones.

Acute cholecystitis: how to avoid subtotal cholecystectomy-preliminary results.

BACKGROUND: The aim of this manuscript is to illustrate a new method permitting safe cholecystectomy in terms of complications with respect to the common bile duct (CBD). METHODS: The core of this new technique is identification of the continuity of the cystic duct with the infundibulum. The cystic duct can be identified between the inner gallbladder wall and inflamed outer wall. RESULTS: In the last 2 years, from January 2019 until December 2021, 3 patients have been treated with the reported technique without complications. CONCLUSIONS: Among the various cholecystectomy procedures, this is a new approach that ensures the safety of the structures of Calot's triangle while providing the advantages gained from total removal of the gallbladder.

[Causes and Countermeasures of Complications After Bariatric Surgery].

Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy characterized by simple operation and few postoperative complications have gradually become the two most commonly used surgical methods in clinical practice.A series of complications often occur after bariatric surgery,including gallstone disease,anemia,malnutrition,gastroesophageal reflux disease,kidney stones,and birth defects in offspring of women of childbearing age.There are controversies regarding the causes and countermeasures of these complications.This article mainly reviews the risk factors and countermeasures for the complications after bariatric surgery.

Gallbladder Mysteries: A Diagnostic Dilemma in Mirizzi Syndrome With Acalculous Presentation.

Mirizzi syndrome (MS) is an uncommon condition caused by chronic gallbladder stones, leading to external compression and obstruction of the common hepatic duct. This report details an unusual MS case in a 65-year-old man who experienced right upper abdominal pain, jaundice, fever, and nausea. Diagnostic tests, such as ultrasound and CT scan, indicated acute acalculous cholecystitis resembling MS. However, a magnetic resonance cholangiopancreatography (MRCP) confirmed no gallstones in the biliary system. The patient's laparoscopic cholecystectomy was successful, with tissue analysis revealing intense gallbladder inflammation and epithelial necrosis but no gallstones. This case emphasizes the diagnostic complexities of atypical MS presentations and the need for comprehensive diagnostic methods, including MRCP. Additionally, the report advocates for standardized terminology in medical literature to ensure clear communication among medical professionals.

A case of Vagococcus fluvialis isolated from the bile of a patient with calculous cholecystitis.

BACKGROUND: Chronic cholecystitis, characterized by persistent inflammation of the gallbladder, predominantly stems from the prolonged presence of gallstones. Calculous cholecystitis has demonstrated a consistent escalation in its incidence over time.Gallbladder stones have been recognized as a predisposing factor for the development of biliary tract infections.Concomitantly, there have been substantial shifts in the distribution and resistance profiles of pathogenic microorganisms responsible for biliary tract infections. The timely acquisition of bile samples for pathogen analysis is of paramount importance, given its critical role in guiding judicious clinical pharmacotherapy and enhancing patient prognosis. CASE PRESENTATION: We present a case involving a 66-year-old female patient who had previously undergone subtotal gastrectomy due to diffuse large B-cell lymphoma. The patient was admitted to our institution with complaints of abdominal pain. Subsequent diagnostic evaluation revealed concurrent choledocholithiasis and cholecystolithiasis. The patient underwent surgical cholecystectomy as the therapeutic approach. Histopathological examination of the excised gallbladder disclosed characteristic features indicative of chronic cholecystitis. Subsequent laboratory analysis of the patient's bile specimen yielded Gram-positive cocci, subsequently identified through biochemical assays, mass spectrometry, and 16 S rRNA analysis as Vagococcus fluvialis. Further in vitro antimicrobial susceptibility testing using disk diffusion and microfluidic dilution showed that this strain exhibited inhibition zone diameters ranging from 12.0 to 32.0 mm in response to 26 antibiotics, including ampicillin, cefazolin, cefuroxime, cefotaxime, ceftriaxone, cefepime, ampicillin/sulbactam, piperacillin, ciprofloxacin, cefoperazone/sulbactam, imipenem, meropenem, piperacillin/tazobarb, penicillin, erythromycin, chloramphenicol, vancomycin, methotrexate/sulfamethoxazole, teicoplanin, linezolid, tigecycline, cefoxitin, ceftazidime, levofloxacin, minocycline and tobramycin. However, the inhibition zone diameters were 6.0 mm for amikacin, oxacillin, clindamycin, and tetracycline. The patient received ceftazidime anti-infective therapy both preoperatively and within 24 h postoperatively and was discharged successfully one week after surgery. CONCLUSION: In this study, we present the inaugural isolation and identification of Vagococcus fluvialis from bile specimens of patients afflicted with calculous cholecystitis. This novel finding lays a substantial experimental groundwork for guiding clinically rational antimicrobial therapy and advancing the exploration of relevant pathogenic mechanisms pertaining to Vagococcus fluvialis infections.

Evidence-based clinical practice guidelines for cholelithiasis 2021.

The Japanese Society of Gastroenterology first published evidence-based clinical practice guidelines for cholelithiasis in 2010, followed by a revision in 2016. Currently, the revised third edition was published to reflect recent evidence on the diagnosis, treatment, and prognosis of cholelithiasis conforming to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. Following this revision, the present English version of the guidelines was updated and published herein. The clinical questions (CQ) in the previous version were reviewed and rearranged into three newly divided categories: background questions (BQ) dealing with basic background knowledge, CQ, and future research questions (FRQ), which refer to issues that require further accumulation of evidence. Finally, 52 questions (29 BQs, 19 CQs, and 4 FRQs) were adopted to cover the epidemiology, pathogenesis, diagnosis, treatment, complications, and prognosis. Based on a literature search using MEDLINE, Cochrane Library, and Igaku Chuo Zasshi databases for the period between 1983 and August 2019, along with a manual search of new information reported over the past 5 years, the level of evidence was evaluated for each CQ. The strengths of recommendations were determined using the Delphi method by the committee members considering the body of evidence, including benefits and harms, patient preference, and cost-benefit balance. A comprehensive flowchart was prepared for the diagnosis and treatment of gallbladder stones, common bile duct stones, and intrahepatic stones, respectively. The current revised guidelines are expected to be of great assistance to gastroenterologists and general physicians in making decisions on contemporary clinical management for cholelithiasis patients.

Intra-abdominal abscess from dropped gallstone: A case report.

Dropped gallstones are a common complication during a laparoscopic cholecystectomy. The formation of an abdominal abscess related to the dropped gallstones is rare because the majority of these calculi do not cause complications. Ultrasound is a usually used first-line imaging modality to detect gallstones in the abscess. CT scan may be used to confirm the diagnosis of abscess and for topographic analysis. We report the case of a lady presented to the emergency department 2 months after laparoscopic cholecystectomy; for acute cholecystitis; with acute abdomen and fever. Laboratory values revealed an elevated white blood cell count (WBC) and C-reactive protein concentration (CRP). The diagnosis of intra-abdominal abscess was evoked by ultrasound and contrast-enhanced CT, and confirmed by laparoscopy. The purpose of this paper is to illustrate the importance of searching and recognizing dropped gallstone within collection, particularly in the context of previous laparoscopic cholecystectomy.

Is hyperleptinemia associated with gallstone disease? A systematic review and meta-analysis.

BACKGROUND: Obesity is one of the risk factors for gallstone disease (GD). Leptin hormone is known to regulate central obesity. Thus, hyperleptinemia may also be involved in gallstone disease pathogenesis. In the present study, a meta-analysis was performed to compare the leptin levels in GD and controls. METHODS: The authors reviewed studies till April 12, 2021, which reported the serum leptin levels in gallstone patients and healthy controls. The online search involved ScienceDirect and PubMed databases. The data obtained from the research articles was scrutinized for selection criteria. Only those articles which fulfilled the inclusion criteria were subjected to meta-analysis. RESULTS: Of 2047 articles, a total of eight studies met the inclusion and exclusion criteria and were considered for the meta-analysis. After meta-analysis, it was observed that the patients with GD  had high leptin levels as compared to healthy controls. A significant level of heterogeneity was observed in the included studies (I2 = 89%, p < 0.01). There was no publication bias. CONCLUSION: High leptin levels might be involved in GD pathogenesis.

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.

Perforated Emphysematous Cholecystitis: A Race Against Time.

Emphysematous cholecystitis is a rare infection of the gallbladder that stems from acute cholecystitis. It can rapidly progress and perforate the gallbladder, which would require urgent surgical intervention. A perforated gallbladder can be diagnosed using an abdominal computed tomography by confirming the presence of air in the gallbladder lumen with adjacent extraluminal air. The causes of ruptured emphysematous cholecystitis include, but are not limited to, diabetes, atherosclerotic changes in blood vessels, and infection with Clostridium perfringens, Escherichia coli, and Klebsiella spp., and is usually present in diabetic men. We report on a 57-year-old female who developed gall bladder perforation with an overflow of gallstones into the peritoneum without a history of diabetes or atherosclerotic disease. Due to the vast availability of computerized tomography and early surgical intervention, the rate of mortality due to perforated emphysematous cholecystitis has decreased over the last few decades.

A systematic study on 33 gallbladder stones resembling adult Clonorchis sinensis worms.

Limited studies provide direct evidence of Clonorchis sinensis adults in the early stage of gallbladder stone formation. Our current research systematically studied 33 gallbladder stones resembling adult worms and shed light on the definite connection of C. sinensis infection with concomitant cholelithiasis. A total of 33 gallbladder stones resembling adult C. sinensis worms were systematically analysed. Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray energy spectrometry were used to analyse the composition and microstructure. Meanwhile, a histopathological examination of the stone was carried out. The 33 gallbladder stones resembling adult C. sinensis worms included nine calcium carbonate (CaCO3) stones, 12 bilirubinate stones and 12 mixed stones. Clonorchis sinensis eggs were found in 30 cases, including all CaCO3 and mixed stones. Parasite tissues were detected in 12 cases, which were mainly CaCO3 stones or bilirubinate-CaCO3 mixed stones. The outer layer of stones was wrapped with 12.88% calcium salt, as revealed by X-ray energy spectrometry, while surprisingly, many C. sinensis eggs were found in the inner part of these stones. Based on our current findings, we concluded that calcification and packaging occurred after C. sinensis adult entrance into the gallbladder, subsequently leading to the early formation of CaCO3 or bilirubinate-CaCO3 mixed gallbladder stones. This discovery highlights definite evidence for C. sinensis infection causing gallbladder stones.
