Antibiotic Therapy of 3 Days May Be Sufficient After Biliary Drainage for Acute Cholangitis: A Systematic Review.

ABSTRACT:

Background

The optimal antibiotic therapy duration for cholangitis is unclear. Guideline recommendations vary between 4 and 14 days after biliary drainage. Clinical observations and some evidence however suggest that shorter antibiotic therapy may be sufficient.

Objective

To compare the effectiveness and safety of short-course therapy of ≤ 3 days with long-course therapy of ≥ 4 days after biliary drainage in cholangitis patients.

Methods

We searched the databases PubMed, EMBASE, Cochrane Library, and trial registers for literature up to August 5, 2020. RCTs and observational studies including case series reporting on antibiotic therapy duration for acute cholangitis were eligible for inclusion. Two reviewers independently evaluated study eligibility, extracted data, assessed risk of bias and quality of evidence. A meta-analysis was planned if the included studies were comparable with regard to important study characteristics. Primary outcomes included recurrent cholangitis, subsequent other infection, and mortality.

Results

We included eight studies with 938 cholangitis patients. Four observational studies enrolled patients treated for ≤ 3 days. Recurrent cholangitis occurred in 0-26.8% of patients treated with short-course therapy, which did not differ from long-course therapy (range 0-21.1%). Subsequent other infection and mortality rates were also comparable. Quality of available evidence was very low.

Conclusion

There is no high-quality evidence available to draw a strong conclusion, but heterogeneous observational studies suggest that antibiotic therapy of ≤ 3 days is sufficient in cholangitis patients with common bile duct stones.

Techniques of biliary drainage for acute cholangitis: Tokyo Guidelines.

Project description:Biliary decompression and drainage done in a timely manner is the cornerstone of acute cholangitis treatment. The mortality rate of acute cholangitis was extremely high when no interventional procedures, other than open drainage, were available. At present, endoscopic drainage is the procedure of first choice, in view of its safety and effectiveness. In patients with severe (grade III) disease, defined according to the severity assessment criteria in the Guidelines, biliary drainage should be done promptly with respiration management, while patients with moderate (grade II) disease also need to undergo drainage promptly with close monitoring of their responses to the primary care. For endoscopic drainage, endoscopic nasobiliary drainage (ENBD) or stent placement procedures are performed. Randomized controlled trials (RCTs) have reported no difference in the drainage effect of these two procedures, but case-series studies have indicated the frequent occurrence of hemorrhage associated with endoscopic sphincterotomy (EST), and complications such as pancreatitis. Although the usefulness of percutaneous transhepatic drainage is supported by the case-series studies, its lower success rate and higher complication rates makes it a second-option procedure.

Antimicrobial therapy of 3 days or less is sufficient after successful ERCP for acute cholangitis.

Project description:BACKGROUND:Recommendations for the duration of antimicrobial therapy in cholangitis after successful endoscopic biliary drainage vary. The aim of this study was to compare the occurrence of local infectious complications in patients with acute cholangitis treated with antibiotics for 3 days or less compared with 4 days or more. METHODS:We performed a retrospective multicentre study in seven hospitals in the Netherlands. Patients who received a successful biliary drainage by endoscopic retrograde cholangio-pancreatography because of cholangitis due to common bile duct stones between 2012 and 2017 were included. The primary outcome was the occurrence of a local infectious complication within 3 months of endoscopic retrograde cholangio-pancreatography. Secondary outcomes included Clostridioides difficile infection, total length of hospital stay and all-cause mortality. RESULTS:A total of 426 patients with cholangitis were identified and 296 patients met all inclusion criteria. Therapy duration was ?3 days in 137 patients (46.3%). During follow-up, 41 patients (13.9%) developed a local infectious complication. Occurrence of infectious complications did not differ between the two groups (p?=?0.32). No patient developed Clostridioides difficile infection. Median hospital stay was 6 days (interquartile range 4-8 days) in the short antibiotic group compared with 7 days (interquartile range 5-9 days) in the long group (p?=?0.03). Four (1.4%) patients died during follow-up, all were treated for ?4 days (p?=?0.13). CONCLUSIONS:Antimicrobial therapy of 3 days or less seems to be sufficient after successful biliary drainage in patients with acute cholangitis. Randomized trials should confirm our findings.

Methods and timing of biliary drainage for acute cholangitis: Tokyo Guidelines.

Project description:Biliary drainage is a radical method to relieve cholestasis, a cause of acute cholangitis, and takes a central part in the treatment of acute cholangitis. Emergent drainage is essential for severe cases, whereas patients with moderate and mild disease should also receive drainage as soon as possible if they do not respond to conservative treatment, and their condition has not improved. Biliary drainage can be achieved via three different routes/procedures: endoscopic, percutaneous transhepatic, and open methods. The clinical value of both endoscopic and percutaneous transhepatic drainage is well known. Endoscopic drainage is associated with a low morbidity rate and shorter duration of hospitalization; therefore, this approach is advocated whenever it is applicable. In endoscopic drainage, either endoscopic nasobiliary drainage (ENBD) or tube stent placement can be used. There is no significant difference in the success rate, effectiveness, and morbidity between the two procedures. The decision to perform endoscopic sphincterotomy (EST) is made based on the patient's condition and the number and diameter of common bile duct stones. Open drainage, on the other hand, should be applied only in patients for whom endoscopic or percutaneous transhepatic drainage is contraindicated or has not been successfully performed. Cholecystectomy is recommended in patients with gallbladder stones, following the resolution of acute cholangitis with medical treatment, unless the patient has poor operative risk factors or declines surgery.

Short Versus Long Antibiotic Therapy and Risk of Recurrence of Acute Cholangitis Due to Malignant Biliary Strictures.

Project description:Malignancies can cause severe stenosis of the biliary tract and therefore predispose a patient to bacterial cholangitis. Upon endoscopic drainage, antibiotic therapy (AT) is performed according to individual clinical judgement, as the optimal duration of AT is unclear to date, especially in the case of multidrug-resistant organisms (MDROs). In a case-based retrospective study, patients with malignant biliary strictures and acute cholangitis were included upon endoscopic retrograde cholangiography (ERC). The outcome of cases treated with short AT (≤6 days) was compared to that of long AT (≥7 days). Recurrent cholangitis (RC) before scheduled stent exchange was the primary end point. In total, 124 patients were included, with 183 cases of proven cholangitis in total. The overall median duration of AT was 7 days (range 1-20), with 74 cases (40%) receiving short AT and 109 (60%) receiving long AT. Short AT was not an independent risk factor for RC (HR = 0.66, p > 0.2), while colonization with MDROs was associated with a higher risk of RC (HR = 2.21, p = 0.005). Placement of a metal stent was associated with minor risk of RC (HR = 0.4, p = 0.038). In conclusion, short AT is possible in selected patients with non-severe cholangitis and malignant biliary strictures. Scheduled screening for MDROs is recommended and placement of a metal stent should be performed if possible.

Procalcitonin to Predict Severity of Acute Cholangitis and Need for Urgent Biliary Decompression: Systematic Scoping Review.

Project description:Serum procalcitonin (PCT) has been reported as a potential biomarker to predict the severity of acute cholangitis (AC) or the need for urgent biliary decompression. This study aimed to identify and summarize the existing research about serum PCT and the severity of AC, and to find gaps towards which future studies can be targeted. Following the PRISMA extension for scoping reviews, MEDLINE, EMBASE, and Google Scholar were searched for all peer-reviewed articles with relevant keywords including "cholangitis" and "procalcitonin" from their inception to 13 July 2021. We identified six studies. All the studies employed a case-control design and aimed to evaluate the usefulness of serum PCT to predict the severity of AC with key identified outcomes. While the potential cut-off values of serum PCT for severe AC ranged from 1.8-3.1 ng/mL, studies used different severity criteria and the definition of urgent biliary decompression. No studies proposed cut-off PCT values for the need for urgent biliary decompression. This scoping review identified the current level of evidence regarding the usefulness of serum PCT in assessing the severity of AC. Further clinical research is warranted with a focus on standardized outcome measures employing prospective or experimental designs.

EUS-guided biliary drainage: A systematic review and meta-analysis.

Project description:ERCP is the current procedure of choice for patients with jaundice caused by biliary obstruction. EUS-guided biliary drainage (EUS-BD) has emerged as an alternative to ERCP in patients requiring biliary drainage. The aim of the study was to conduct a systematic review and meta-analysis to report the overall efficacy and safety of EUS-BD. We conducted a comprehensive search of several databases including PubMed, EMBASE, Web of Science, Google Scholar, and LILACS databases (earliest inception to June 2018) to identify studies that reported EUS-BD in patients. The primary outcome was to look at the technical and clinical success of the procedure. The secondary analysis focused on calculating the pooled rate of re-interventions and all adverse-events, along with the commonly reported adverse-event subtypes. Twenty-three studies reporting on 1437 patients were identified undergoing 1444 procedures. Majority of the patient population were male (53.86%), with an average age of 67.22 years. The pooled technical success rates and clinical success rates were 91.5% (95% confidence interval [CI]: 87.7-94.2, I[2] = 76.5) and 87% (95% CI: 82.3-90.6, I[2] = 72.4), respectively. The total adverse event rates were 17.9% (95% CI: 14.3-22.2, I[2] = 69.1). Subgroup analysis of three major individual adverse events was bile leak: 4.1% (2.7-6.2, I[2] = 46.7), stent migration: 3.9% (2.5-6.2, I[2] = 43.5), and infection: 3.8% (2.8-5.1, I[2] = 0) Substantial heterogeneity was noted in the analysis. EUS-BD has high technical and clinical success rate and hence a very effective procedure. Concerns about publication bias exist. Careful consideration should be given to the adverse events and weighing the risks and benefits of the alternative nonsurgical/surgical approaches.

A Systematic Review of Patient-Reported Outcomes in Primary Biliary Cholangitis and Primary Sclerosing Cholangitis.

Project description:Primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) are associated with decreased health-related quality of life and debilitating symptoms. These experiences can be defined as patient-reported outcome (PRO) concepts and measured using PRO instruments. We identified all PRO concepts and instruments used in the PBC and PSC literature. This systematic review identified PBC and/or PSC studies from January 1, 1990, to May 6, 2019, that measured at least one PRO concept. Study population, design, PRO concept, PRO instrument, and validation data for PRO instruments were investigated. We provided descriptive statistics of PRO concepts and instruments used, stratified by population type. Use of PRO concepts and instruments were assessed over time. The search yielded 318 articles (69% in PBC, 18% in PSC, 13% in both, and 24% in drug trials). Forty-nine unique PRO concepts were identified. The five most common PRO concepts included pruritus (25%), fatigue (19%), broad health-related quality of life (16%), gastrointestinal adverse events (6%), and physical adverse events (6%). Only 60% of PRO concepts were measured with a PRO instrument, most of which were nonvalidated visual analogue or numeric rating scales. Only three of 83 PRO instruments were developed with feedback from the target populations (one for PBC, one for PSC, and one for both), and only six documented any psychometric testing in the target populations. Use of PRO instruments increased over time from 30% in the 1990s to 67% by 2019. Conclusion: The overwhelming majority of PRO instruments used in PBC/PSC were nonspecific and lacked patient validation or empirical justification. Significant opportunities exist to use qualitative methods to better understand patient experiences, and translate this knowledge into meaningful, patient-driven study outcomes.

Cholestatic Pruritus Treatments in Primary Biliary Cholangitis and Primary Sclerosing Cholangitis: A Systematic Literature Review.

Project description:Background and aimsWe conducted a systematic literature review to understand the evidence supporting treatment decisions for cholestatic pruritus associated with primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC).MethodsStudies that enrolled ≥ 75% participants with PBC or PSC and reported ≥ 1 endpoint(s) related to efficacy, safety, health-related quality of life (HRQoL) or other patient-reported outcomes were included. Bias was assessed using the Cochrane risk of bias tool for randomised controlled trials (RCTs) and the Quality of Cohort studies tool for non-RCTs.ResultsThirty-nine publications were identified, covering 42 studies and six treatment classes (including investigational and approved products): anion-exchange resins, antibiotics (rifampicin/derivatives), opiates, selective serotonin reuptake inhibitors, fibrates, ileal bile acid transporter inhibitors and other agents not categorised in these six classes. Across studies, median sample size was small (n = 18), 20 studies were over 20 years old, 25 followed patients for ≤ 6 weeks, only 25 were RCTs. Pruritus was assessed using several different tools, with inconsistencies in their application. Cholestyramine, considered first-line therapy for moderate-severe cholestatic pruritus, was assessed in six studies (two RCTs) including 56 patients with PBC and 2 with PSC, with evidence of efficacy demonstrated in only three studies, among which, two RCTs were assessed as having a high risk of bias. Findings were similar for other drug classes.ConclusionsThere is a lack of consistent and reproducible evidence available on efficacy, impact on HRQoL, and safety of cholestatic pruritus treatments, leaving physicians to rely on clinical experience rather than evidence-based medicine for treatment selection.

Endoscopic Biliary Darinage (EBD) versus Percutaneous Transhepatic Biliary Drainage (PTBD) for biliary drainage in patients with Perihilar Cholangiocarcinoma (PCCA): A systematic review and meta-analysis.

Project description:Biliary drainage for Perihilar Cholangiocarcinoma (PCCA) can be performed either by endoscopic retrograde cholangiopancreatography or Percutaneous Transhepatic Biliary Drainage (PTBD). To date there is no consensus about which method is preferred. Taking that into account, the aim of this study is to compare Endoscopic Biliary Drainage (EBD) versus percutaneous transhepatic biliary drainage in patients with perihilar cholangiocarcinoma through a systematic review and metanalysis. A comprehensive search of multiple electronic databases was performed. Evaluated outcomes included technical success, clinical success, post drainage complications (cholangitis, pancreatitis, bleeding, and major complications), crossover, hospital length stay, and seeding metastases. Data extracted from the studies were used to calculate Mean Differences (MD). Seventeen studies were included, with a total of 2284 patients (EBD = 1239, PTBD = 1045). Considering resectable PCCA, the PTBD group demonstrated lower rates of crossover (RD = 0.29; 95% CI 0.07‒0.51; p = 0.009 I² = 90%), post-drainage complications (RD = 0.20; 95% CI 0.06‒0.33; p < 0.0001; I² = 78%), and post-drainage pancreatitis (RD = 0.10; 95% CI 0.05‒0.16; p < 0.0001; I² = 64%). The EBD group presented reduced length of hospital stay (RD = -2.89; 95% CI -3.35 ‒ -2,43; p < 0.00001; I² = 42%). Considering palliative PCCA, the PTBD group demonstrated a higher clinical success (RD = -0.19; 95% CI -0.27 ‒ -0.11; p < 0.00001; I² = 0%) and less post-drainage cholangitis (RD = 0.08; 95% CI 0.01‒0.15; p = 0.02; I² = 48%) when compared to the EBD group. There was no statistical difference between the groups regarding: technical success, post-drainage bleeding, major post-drainage complications, and seeding metastases.

Short-Course Antibiotic Treatment Is Not Inferior to a Long-Course One in Acute Cholangitis: A Systematic Review.

Project description:AimsOur aim was to summarize the available literature on the effect of short- versus long-course antibiotic therapy on acute cholangitis.MethodsA systematic review was performed according to the PRISMA Statement. We searched three databases for papers discussing the length of ABT in acute cholangitis. Long and short therapy groups were defined based on the most recent guideline available at the time of publication of the articles. Primary outcomes were the rate of recurrent cholangitis and mortality; secondary outcomes included length of hospitalization and the duration of fever after ERCP. Data were extracted on these outcomes and on general characteristics. A narrative synthesis was then provided based on collected data.ResultsOut of 692 articles produced by our search, four met our inclusion and exclusion criteria. These contained 205 acute cholangitis patients, with 137 and 68 patients receiving short and long antibiotic therapy, respectively. No significant difference was observed in any of the studies on the outcomes of mortality and duration of fever after ERCP between the two groups. One out of four studies found the rate of recurrent cholangitis to be significantly lower in the short antibiotic therapy group (0.0% vs. 13.3%, p = 0.036). Length of hospitalization was only compared in the same retrospective article, where it was found to be significantly shorter in the short-term antibiotic therapy group (with a median of 14 vs. 17.5 days, p < 0.001).ConclusionsOur review suggests short-course antibiotic therapy is non-inferior to long-course treatment; however, several limitations underline the need for well-designed randomized trials.
