Dilated common bile duct diameter as an indicator of bacteremia in patients with symptomatic common bile duct stones

BackgroundThe optimal timing and selection for blood culture collection in patients with acute cholangitis remains unclear. The relationship between common bile duct (CBD) diameter and the incidence of bacteremia in patients with CBD stones was elucidated. MethodsThis single-center retrospective observational study included patients with symptomatic CBD stones who presented to the emergency department between January 2019 and December 2021. The primary endpoint was the incidence of bacteremia. The patients were divided into two groups based on bacteremia complications. The patient characteristics and CBD diameters were compared between the two groups to identify factors associated with bacteremia. ResultsIn total, 270 patients were analyzed, with bacteremia identified in 134 patients (50 %), and the median CBD diameter was 10.7 mm (IQR, 8.7–13.7). The CBD diameter was significantly larger in patients with bacteremia (median 12.4 mm [IQR, 9.9–15.7] vs. 9.7 mm [IQR, 8.2–11.7], P < 0.001) in univariate analysis. Multivariable analysis revealed that the CBD diameter was significantly associated with bacteremia (OR: 1.25, 95 % CI: 1.14–1.38, P < 0.010). The area under the ROC curves, representing the diagnostic accuracy of CBD diameter for indicating bacteremia, was 0.72 (95 % CI, 0.66–0.78) with a cut-off value of 11.2 mm. ConclusionCBD dilation in patients with symptomatic CBD stones is significantly correlated with bacteremia. The CBD diameter cannot be assessed as the sole tool for detecting bacteremia; however, CBD dilation could be an indicator of bacteremia, assisting in the treatment strategy, regardless of the initial severity of cholangitis.

Microbiology of Acute Cholangitis and Cholecystitis and Antimicrobial Susceptibility

Microbiology of Acute Cholangitis and Cholecystitis and Antimicrobial Susceptibility

Diagnosis and Treatment of Choledochal Cysts: A Comprehensive Review with a Focus on Choledochocele.

Choledochal cysts (CCs) are cystic dilations of intrahepatic and/or extrahepatic bile ducts. Around 80% of CCs are diagnosed within the first decade of life. These complex clinical entities are extremely rare, especially in the Western population. CCs are frequently classified according to the Todani classification. CCs may be asymptomatic or present as acute pancreatitis and/or cholangitis, biliary obstruction, or malignancy. Therefore, the diagnosis relies primarily on abdominal imaging modalities, mainly magnetic resonance cholangiopancreatography. Management is tailored based on the cyst morphology and the patient's clinical characteristics, with surveillance, surgery, and interventional endoscopy being the most frequent management options. While the surgical approach is the most frequently employed, type III CCs (also known as choledochocele) are frequently managed endoscopically, and novel endoscopic, minimally invasive treatment options are rapidly emerging.

The safety and efficacy of primary duct closure after laparoscopic common bile duct explorationin patients withmild-to-moderate calculus-associated acute cholangitis: a retrospective cohort study.

While laparoscopic common bile duct exploration with primary duct closure (LCBDE + PDC) has been considered a feasible and safe treatment for cholecystocholedocholithiasis, uncertainties remain regarding its effectiveness and safety in patients with mild-to-moderate calculus-associated acute cholangitis. Therefore, this study aims to investigate the safety and efficacy of LCBDE + PDC specifically in patients with mild-to-moderate acute cholangitis (AC). Patients with cholecystocholedocholithiasis who underwent LCBDE + PDC treatment at our hospital between July 2020 and September 2022 were included. The patients were divided into two groups based on the presence of cholangitis: acute cholangitis (AC group) and non-acute cholangitis (non-AC group). A total of 136 patients underwent LCBDE + PDC treatment, with 65 in the AC group and 71 in the non-AC group. No deaths occurred after surgery in either group. The AC group had longer drainage tube retention time (5 (4-7)days vs. 4 (3-5)days, P < 0.001), postoperative hospital stay (8 (6-9)days vs. 6 (5-7)days, P < 0.001), and total hospital stay (12 (9.5-15)days vs. 10 (8-13)days, P < 0.001) compared to the non-AC group. However, there were no significant differences between the two groups in terms of operation time, estimated blood loss, and the rate of using holmium laser lithotripsy. The incidence of postoperative complications was similar between the two groups. Our study demonstrates that LCBDE + PDC is a safe and feasible treatment for patients with mild-to-moderate calculus-associated acute cholangitis who meet the criteria for primary duct closure.

Diagnostic and Therapeutic Value of Endoscopic Retrograde Cholangiopancreatography in Acute Cholangitis: A Study From Kashmir Valley, India

Diagnostic and Therapeutic Value of Endoscopic Retrograde Cholangiopancreatography in Acute Cholangitis: A Study From Kashmir Valley, India

Vibrio fluvialis Bacteremia in an Immunocompetent Patient with Acute Cholangitis.

Vibrio fluvialis is a bacterium that can be found in both seawater and freshwater, and it is responsible for causing gastroenteritis and cholangitis. V. fluvialis bacteremia has rarely been reported. We report a case of V. fluvialis bacteremia due to cholangitis in an immunocompetent adult who was exposed to seawater regularly as a sushi chef. The increased risk of V. fluvialis entry into the body resulting from frequent consumption of raw fish and regular exposure to seawater, bile outflow impairment caused by transient inflammation of the bile duct, and the presence of multiple bile acid resistance-related genes in V. fluvialis may lead to the development of acute cholangitis and subsequent bacteremia in immunocompetent patients.

Navigating antibiotic therapy in acute cholangitis: Best practices and new insights.

Globally, antibiotic resistance is linked to increased morbidity, mortality, and healthcare costs, which necessitates further research on optimal antibiotic usage. Acute cholangitis (AC), a common cause of community-acquired bacteremia, often requires antimicrobial therapy. Therefore, studying the appropriate use of antibiotics for AC is considered crucial for suppressing the emergence of resistant bacteria and reducing adverse antibiotic-associated events. The Tokyo Guidelines 2018 (TG18) recommend 4-7 days of antibiotics post-biliary drainage. However, this lacks strong evidence and is based primarily on various evidence and expert opinions. Recent retrospective studies advocate for a shorter 1-3-day antibiotic course for AC, thereby prompting a need to reassess the treatment duration to balance therapeutic efficacy and minimize resistance and adverse effects. Choosing the appropriate duration and antibiotics based on susceptibility to pathogens causing cholangitis is important. Awareness of local resistance patterns and understanding patients' risks of resistant pathogens are prerequisite for effective treatment. We must explore the applicability of these guidelines in specific scenarios such as severe AC, positive blood cultures, fever, or hilar biliary obstructions due to malignancy. This comprehensive review considers both the duration and type of antibiotics and aims to enhance treatment outcomes while reducing the risk of resistant bacterial infections.

BN SO51 - Complications from operative cholangiogram during emergency laparoscopic cholecystectomy: A retrospective, observational cohort study in a UK single centre

Abstract Background Laparoscopic cholecystectomy (LC) is a common surgical procedure, with &amp;gt;60,000 undertaken annually in the UK. One serious complication of cholecystectomy is bile-duct-injury (BDI), with an incidence of 0.28–1.5%. The use of intraoperative-cholangiogram (OTC) has been shown to aid in earlier diagnosis and treatment of BDI. Although advocated as routine by many, no studies have assessed the morbidity caused by OTC. With newer modalities available, such as indocyanine-green-fluorescent-cholangiography (ICGC) and three-dimensional laparoscopy, it is important to consider each method's risks and benefits, including OTC. We decided to investigate the morbidity caused by OTC with an emphasis on post-OTC acute pancreatitis. Method We conducted a retrospective cohort study of a prospectively collected cohort of patients aged 18 and over who have undergone emergency LC, defined as LC within seven days from admission with acute cholecystitis, over three years in a UK district general hospital. The primary outcome studied was the incidence of complications following OTC, including acute pancreatitis (AP), acute cholangitis, extra-hepatic biliary tree injury and hepatic abscess. The STROBE (STrengthening the Reporting of OBservational studies in Epidemiology) checklist was utilised. We used GraphPad Prism 10.2.3. for statistical analysis. Results 472 cases were analysed. Median age was 54(A), BMI 31(C), ASA grade 2(D), clinical frailty score 2(E), Charlson Comorbidity Index 1(F), Tokyo severity grade 1(K) and female-to-male ratio 0.83(B). 14.31% of cases had pre-op CBD dilatation, 0.42% CBD stones and 6.19% both, with most having ultrasound pre-op (J-I). The median Nassar score was 3(L). 24.57 % of cases had an OTC done, with a median volume of contrast-media used of 11(6;24.5) mls, with 17 cases having CBD stones diagnosed(M-O). Four cases, or 3.44% of the total OTCs, developed acute pancreatitis (P). Conclusion Emergency laparoscopic cholecystectomy with intraoperative cholangiogram may increase the risk of postoperative acute pancreatitis.

HPB SO71 - Meta-Anaylsis of Early Endoscopic Retrograde Cholangiopancreatography versus conservative management for gallstone pancreatitis

Abstract Background Acute pancreatitis is one of the most common gastrointestinal causes of hospital admission. The most common cause is transient blockage of the bile or pancreatic duct (or both) by gallstones. Most of the time, pancreatitis responds to conservative management (CM) comprising intravenous fluid hydration and analgesia. ERCP +/_endoscopic sphincterotomy in acute gallstone pancreatitis has been advocated in the past to decrease the number of complications of this condition. However, the role and timing of this procedure are still contentious and an ongoing debate. Method The aim of this study is to compare the clinical outcomes of early urgent ERCP versus conservative management in biliary pancreatitis but not cholangitis. An online search of Medline, Embase, Science citation index, PubMed and Cochrane database of systematic reviews published between 1988 and 2022 was carried out for relevant studies. Statistical analysis was done using Revman 5.4 and Odds ratio with a 95% Confidence interval was used for outcome estimation. There was 14 studies included in the final study consisting a total of 1756 patients with 877 patients in ERCP group while 879 in CM group. Results With random effects model, data showed no significant reduction in mortality in ERCP group as compared to the CM group (OR 0.59, 95% CI 0.30-1.16; p=0.13). However there were overall more local or systemic complications (OR 0.51, 95% CI 0.36-0.71; p&amp;lt;0.002) in the CM group as compared to ERCP group. No statistically significant difference found amongst groups when comparing complications as renal failure(OR-0.99, 95% CI-0.41-2.41, p=0.98), cardiac failure (OR-0.77 95% CI 0.35-1.69, p=0.51) or biliary sepsis (OR-0.56 95%CI 0.15-2.10, p=0.39) but there was more incidence of pseudocyst in CM group patients(OR-0.47, 95% CI 0.25-0.87, p=0.02). Conclusion The above study did show that the mortality rate was not significantly higher in the CM group as compared to the ERCP group however the early ERCP was beneficial in reducing overall complications in the interventional group. Based on this fact, ERCP considered early in the management of acute pancreatitis despite of still being debatable in practice can be considered in severe pancreatitis cases and further high powered randomized controlled trials can be carried out to assess this point.

Sarcopenia is associated with new-onset acute biliary infection within 1 year in patients with hepatitis B virus-related decompensated cirrhosis.

Malnutrition and sarcopenia are prevalent complications in cirrhosis. The relationship between sarcopenia and biliary infection in cirrhotic patients is not well understood. Our study aims to clarify this association. In this study, we leveraged data from a tertiary care hospital, enrolling patients with hepatitis B virus (HBV)-induced cirrhosis from 2022. An acute biliary tract infection was defined as the onset of acute cholecystitis or cholangitis within a year. Sarcopenia was identified based on established criteria and assessed using the L3 skeletal muscle index (SMI). A multivariate logistic regression model was constructed to analyze the relationship between sarcopenia and acute biliary tract infection. Receiver operating characteristic (ROC) curve analysis and smooth curve fitting were also conducted. This study enrolled a total of 262 patients with HBV-related cirrhosis, with an average age of 60 years and including 173 males. The primary causes for hospital admission were ascites and hepatic encephalopathy. Within the group with biliary infection, patients typically presented with higher white blood cell counts, lower platelet levels, and poorer indicators of liver and kidney function. In the multivariate analysis, after adjusting for various confounding factors, sarcopenia was associated with an odds ratio of 1.55 (P = 0.002) for acute biliary infection. Smooth curve fitting revealed an approximately linear positive relationship between L3 SMI and acute biliary infection, with the area under the ROC curve for L3 SMI reaching 0.89, indicating a strong predictive value. Sarcopenia is associated with acute biliary infection in patients with HBV-related cirrhosis.

Identification of risk factors associated with post-ERCP pancreatitis in patients with easy cannulation: A prospective multicenter observational study

Background and aimsDifficult biliary cannulation is an independent risk factor for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP); however, there is a noticeable lack of studies focusing on the incidence and risk factors of PEP among patients undergoing easy cannulation. Therefore, we aimed to systematically investigate the risk factors for PEP in patients who underwent easy cannulation. MethodsWe prospectively enrolled patients with naïve major papillae who underwent diagnostic or therapeutic ERCP between June 2018 and June 2023. The primary endpoint was to determine the incidence of PEP in patients with easy cannulation; the secondary endpoints included identifying PEP risk factors and evaluating procedure-related adverse events (AEs). ResultsOverall, 1,930 patients were included, with 1,061 (54.9%) undergoing easy cannulation. Within this cohort, PEP incidence was 3.0%, whereas 2.9% experienced procedure-related AEs, excluding PEP. A history of acute pancreatitis (odds ratio [OR] 95% confidence interval [CI]: 6.75 [1.83–20.14], P=0.001) and acute cholangitis upon admission (OR [95% CI]: 2.25 [1.07–5.08], P=0.039) were identified as independent risk factors for PEP in patients with easy cannulation. Endoscopic sphincterotomy and biliary stent placement were independent factors for procedure-related AEs. ConclusionsOur findings underscore the importance of assessing patient- and procedure-related factors to mitigate the risk of PEP in patients undergoing easy cannulation. Despite the low incidence of PEP, the potential for the occurrence of severe cases emphasizes the need for cautious intervention, particularly in patients with a history of acute pancreatitis and acute cholangitis upon admission.

Modulation of Metabolomic Profile in Sepsis According to the State of Immune Activation.

To investigate the metabolomic profiles associated with different immune activation states in sepsis patients. Subgroup analysis of the PROVIDE (a Personalized Randomized trial of Validation and restoration of Immune Dysfunction in severe infections and Sepsis) prospective clinical study. Results of the PROVIDE study showed that patients with sepsis may be classified into three states of immune activation: 1) macrophage-activation-like syndrome (MALS) characterized by hyperinflammation, sepsis-induced immunoparalysis, and 3) unclassified or intermediate patients without severe immune dysregulation. Two hundred ten patients from 14 clinical sites in Greece meeting the Sepsis-3 definitions with lung infection, acute cholangitis, or primary bacteremia. During our comparison, we did not perform any intervention. Untargeted metabolomics analysis was performed on plasma samples from 210 patients (a total of 1394 products). Differential abundance analysis identified 221 significantly different metabolites across the immune states. Metabolites were enriched in pathways related to ubiquinone biosynthesis, tyrosine metabolism, and tryptophan metabolism when comparing MALS to immunoparalysis and unclassified patients. When comparing MALS to unclassified, 312 significantly different metabolites were found, and pathway analysis indicated enrichment in multiple pathways. Comparing immunoparalysis to unclassified patients revealed only two differentially regulated metabolites. Findings suggest distinct metabolic dysregulation patterns associated with different immune dysfunctions in sepsis: the strongest metabolic dysregulation is associated with MALS.

Sump syndrome: Diagnosis dilemmas and therapeutic approaches-A case series.

It is important to consider the diagnosis of Sump syndrome in patients with a history of open cholecystectomy, particularly in those who migrate from developing countries where alternative biliary interventions may be limited. The presentation may range from acute severe, mimicking acute ascending cholangitis, to chronic recurrent abdominal pain without evidence of inflammation. Management is a case-by-case decision, with principal management aims to decompress the biliary tract and address any underlying sepsis. Sump syndrome is a rare and often long-term complication of choledochoduodenostomy (CDD). The presentation and severity are variable, and management should be tailored to each patient based on several factors. Herein, we report three cases of sump syndrome, each demonstrating unique diagnostic dilemmas and therapeutic modalities. Case I describes a woman presenting with acute cholangitis, managed with percutaneous transhepatic cholangiography (PTC) and endoscopic retrograde cholangiopancreatography (ERCP). Case II illustrates a similar presentation complicated by myocardial infarction, necessitating urgent biliary decompression via PTC and subsequent unsuccessful endoscopic stenting. Case III highlights the diagnostic difficulty in a stable patient with inconclusive diagnostic imaging. This case series emphasizes the importance of considering sump syndrome diagnosis in patients with a history of CDD or open cholecystectomy, especially in elderly patients and those who come from regions where alternative biliary interventions may be limited.

Emergency Laparoscopic Common Bile Duct Exploration for Acute Cholangitis in Cases with Difficulty with an Endoscopic Approach

Emergency Laparoscopic Common Bile Duct Exploration for Acute Cholangitis in Cases with Difficulty with an Endoscopic Approach

064. Overview of Bacterial Patterns and Antibiotic Resistance on Cholangitis Patients at Hasan Sadikin General Hospital from January to December 2023

Background: Cholangitis is a serious infection of the bile ducts that requires prompt treatment, often with antibiotic therapy. Although antibiotic use, especially ceftriaxone and metronidazole, is vital in treatment, antibiotic resistance remains a significant challenge. Unfortunately, data on bacterial resistance patterns in cholangitis patients treated at Doctor Hasan Sadikin Hospital in Bandung is still limited. This study aims to describe the bacterial patterns and antibiotic resistance in cholangitis patients at Doctor Hasan Sadikin General Hospital. Another objective is to assess the effectiveness of ceftriaxone and metronidazole therapy in patients with moderate to severe cholangitis. Methods: This research employed a retrospective descriptive design by collecting data from the medical records of acute cholangitis patients treated at Doctor Hasan Sadikin General Hospital from January to December 2023. A total of 126 patient samples meeting the inclusion criteria were analyzed through blood cultures, and sensitivity tests were conducted against various antibiotics. Data were analyzed using SPSS software. Results: The results showed that Escherichia coli (26.3%) was the most commonly found bacterium, followed by Staphylococcus haemolyticus and Klebsiella pneumoniae (each at 13.2%). The highest resistance was observed against ampicillin (78.9%), while the most effective antibiotic was tigecycline (92.1% sensitivity). Conclusion: In conclusion, ceftriaxone and metronidazole as empiric therapy remains effective for most cholangitis patients, although resistance to certain antibiotics like ampicillin warrants attention. This study highlights the importance of regular monitoring of antibiotic resistance patterns to ensure proper treatment and reduce morbidity and mortality rates among cholangitis patients.

Revised Clinical Practice Guideline of Korean Pancreatobiliary Association for Common Bile Duct Stones: Purpose and Process of Guidelines

Common bile duct (CBD) stones carry a risk of complications including biliary obstruction, acute cholangitis and pancreatitis. Endoscopic retrograde cholangiopancreatography (ERCP) is regarded as the standard of treatment for CBD stones nowadays. However, ERCP can cause severe adverse events such as bleeding, post-ERCP pancreatitis and perforation. Therefore, it is important to provide practical guideline to manage CBD stones for clinicians. The Korean Pancreatobiliary Association (KPBA) established the first Korean guidelines for the management of CBD stones in 2013. Taking together the recently developed techniques for CBD stones and evidence newly obtained, the committee of the KPBA decided to perform an extensive revision of the guidelines. These revised guidelines were developed based on consensusbased guideline using Delphi methods. The main topics of these guidelines fall under the following topics: 1) diagnosis, 2) endoscopic management, 3) endoscopic management for difficult CBD stones. The specific recommendations are presented with the quality of evidence and classification of recommendations.

Bacteriological Spectrum in Bile and Outcomes in Patients of Acute Bacterial Cholangitis

Bacteriological Spectrum in Bile and Outcomes in Patients of Acute Bacterial Cholangitis

Clinical Features and Prognosis of Acute Cholangitis in Octogenarians: A Prospective Comparative Study.

Background: The data on acute cholangitis in the octogenarian population are very limited. This study aimed to examine the clinical characteristics of acute cholangitis and complications related to endoscopic retrograde cholangiopancreatography (ERCP) in octogenarians. Materials and Methods: This study was conducted prospectively between July 2022 and December 2023 and included 250 patients aged 65 years and older. Patients eligible for the study were divided into two groups: those aged ≥80 years (octogenarian) and those aged 65-79 years (non-octogenarian). These two groups were compared in terms of the clinical characteristics of cholangitis and ERCP-related complications. In addition, factors associated with in-hospital mortality were evaluated. Results: Out of 250 patients, 87 (34.8%) were octogenarians and 163 (65.2%) were non-octogenarians. The median age was 76 (69-82) years. Although the octogenarian group had higher rates of severe illness and intensive care unit admissions (p < 0.001 and p = 0.002, respectively), there were no significant differences in in-hospital mortality (p = 0.359) or ERCP-related complications (p = 0.417). Malignant etiology (odds ratio [OR]: 5.68, 95% confidence interval [CI]: 2.11-15.3), hypoalbuminemia (OR 0.18, 95% CI 0.07-0.45), and qSOFA score ≥ 2 (OR: 6.5, 95% CI: 1.7-24.5) were independent risk factors for in-hospital mortality. Conclusions: Being over 80 years old is not an indicator of poor outcomes, and ERCP can be safely performed on these patients. However, elderly patients with hypoalbuminemia, malignant etiology, or a qSOFA score of ≥2 should be closely monitored, regardless of their age.

A case of late presentation of recurrent primary choledocholithiasis 30 years post-cholecystectomy: Presentation and management

Acute cholangitis typically occurs secondary to biliary obstruction and bile stasis. While the most common cause is secondary choledocholithiasis (i.e., stones form in the gallbladder and are expelled into the common bile duct), there is little information on primary choledocholithiasis as the principal source of this obstruction. Furthermore, it is particularly rare to see symptomatic choledocholithiasis years to decades later in patients who previously underwent cholecystectomy. We report a complex case of a 75-year-old woman who presented to the emergency department with a 3 to 4-day history of abdominal pain, nausea, generalized weakness, fever, and shortness of breath. She had septic cholangitis due to primary choledocholithiasis 30 years post-cholecystectomy and numerous other comorbidities that increased the complexity of her case. Endoscopic retrograde cholangiopancreatography (ERCP) was attempted to remove the stone but was unsuccessful due to duodenal diverticula. Eventually, this patient underwent common bile duct exploration using a robot-assisted approach. A 2 cm stone at the distal common bile duct was removed, and her clinical status dramatically improved. The efficiency and increased fine control of a robot-assisted approach introduces our idea that this approach should be an alternative management option for minimally invasive common bile duct exploration in patients who have high-risk comorbidities and failed ERCP. Keywords: Acute cholangitis, primary choledocholithiasis, recurrent choledocholithiasis, post-cholecystectomy, robotic-assisted common bile duct exploration

STATE OF CELLULAR IMMUNITY IN PURULENT CHOLANGITIS

Abstract. Objective: To study the state of the cellular link of immunity in acute and chronic cholangitis. Materials and methods. Cholangitis always worsens the condition of the biliary system. Depending on the magnitude of the pathological changes in the bile ducts, we distinguished three groups of patients. Group I – cholangitis caused by obstruction of the main extrahepatic bile ducts due to choledocholithiasis, group II – cholangitis in conditions of cicatricial strictures of the main bile ducts, and group III – cholangitis in conditions of already performed reconstruction of the duct system. The indicators of the cellular link of immunity were studied separately in each group. The results. The conducted studies indicate an imbalance of the immune system in patients with different courses of cholangitis. The presence of inflammation of a mild degree of severity causes stimulation of almost all links of the immune system, while the cellular branch reacts first. Conclusions. Long-term cholangitis was accompanied by suppression of the main markers of T-lymphocyte differentiation — CD2+, CD3+, CD4+ and CD8+, which take part in antigen presentation, signal transmission to other cells and affect their adhesive properties.
