Primary Needle-Knife Sphincterotomy for Biliary Access in Patients at High Risk of Post-Endoscopic Retrograde Cholangiopancreatography Pancreatitis.

ABSTRACT:

Methods

Forty patients with one or more risk factors for PEP were prospectively enrolled between June 2018 and November 2019. The cannulation was conducted in all patients using NKS as the primary cannulation technique. Success rate of biliary cannulation, biliary cannulation time, and adverse event rate were assessed.

Results

Of the 40 patients enrolled, 34 patients underwent primary NKS after the screening. Nine patients had 1 risk factor for PEP, 7 had 2, 8 had 3, 7 had 4, and 3 had 5. The success rate of biliary access by NKS was 94.1% (32/34). The median procedure time for NKS and the total procedure time for stone removal or biliary drainage were 4.1 minutes (range, 0.5-25.2) and 11.3 minutes (range, 3.8-40.4), respectively. Adverse events occurred in two patients (minor bleeding, n = 1; hyperamylasemia, n = 1). No patient experienced PEP or perforation.

Conclusion

NKS might be feasible as a primary cannulation procedure in patients at high risk of PEP. This trial is registered with KCT0004886 (03/06/2018).

Effect of endoscopic transpapillary biliary drainage with/without endoscopic sphincterotomy on post-endoscopic retrograde cholangiopancreatography pancreatitis in patients with biliary stricture (E-BEST): a protocol for a multicentre randomised controlled trial.

Project description:IntroductionThe effect of endoscopic sphincterotomy prior to endoscopic biliary stenting to prevent post-endoscopic retrograde cholangiopancreatography pancreatitis remains to be fully elucidated. The aim of this study is to prospectively evaluate the non-inferiority of non-endoscopic sphincterotomy prior to stenting for naïve major duodenal papilla compared with endoscopic sphincterotomy prior to stenting in patients with biliary stricture.Methods and analysisWe designed a multicentre randomised controlled trial, for which we will recruit 370 patients with biliary stricture requiring endoscopic biliary stenting from 26 high-volume institutions in Japan. Patients will be randomly allocated to the endoscopic sphincterotomy group or the non-endoscopic sphincterotomy group. The main outcome measure is the incidence of pancreatitis within 2 days of initial transpapillary biliary drainage. Data will be analysed on completion of the study. We will calculate the 95% confidence intervals (CIs) of the incidence of pancreatitis in each group and analyse weather the difference in both groups with 95% CIs is within the non-inferiority margin (6%) using the Wald method.Ethics and disseminationThis study has been approved by the institutional review board of Hokkaido University Hospital (IRB: 016-0181). Results will be submitted for presentation at an international medical conference and published in a peer-reviewed journal.Trial registration numberThe University Hospital Medical Information Network ID: UMIN000025727 Pre-results.

Preventing post-endoscopic retrograde cholangiopancreatography pancreatitis: what can be done?

Project description:Post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) is the most common complication of endoscopic retrograde cholangiopancreatography. The incidence of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis varies substantially and is reported around 1%-10%, although there are some reports with an incidence of around 30%. Usually, PEP is a mild or moderate pancreatitis, but in some instances it can be severe and fatal. Generally, it is defined as the onset of new pancreatic-type abdominal pain severe enough to require hospital admission or prolonged hospital stay with levels of serum amylase two to three times greater than normal, occurring 24 h after ERCP. Several methods have been adopted for preventing pancreatitis, such as pharmacological or endoscopic approaches. Regarding medical prevention, only non-steroidal anti-inflammatory drugs, namely diclofenac sodium and indomethacin, are recommended, but there are some other drugs which have some potential benefits in reducing the incidence of post-ERCP pancreatitis. Endoscopic preventive measures include cannulation (wire guided) and pancreatic stenting, while the adoption of the early pre-cut technique is still arguable. This review will attempt to present and discuss different ways of preventing post-ERCP pancreatitis.

Increased Use of Prophylactic Measures in Preventing Post-Endoscopic Retrograde Cholangiopancreatography Pancreatitis.

Project description:BackgroundNonsteroidal anti-inflammatory drugs (NSAIDs), pancreatic duct stenting, and intensive intravenous hydration have been proven to prevent post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. Trial participation and guideline changes demanded an assessment of the clinical practice of post-ERCP pancreatitis prophylaxis.AimsThe surveys aim to identify points of improvement to inform and educate ERCPists about current evidence-based practice.MethodsTwo anonymous surveys were conducted among Dutch gastroenterologists in 2013 (n = 408) and 2020 (n = 575) for longitudinal views and attitudes pertaining to post-ERCP pancreatitis prophylaxis and recognition of post-ERCP pancreatitis risk factors.ResultsIn 2013 and 2020, respectively, 121 and 109 ERCPists responded. In the 2013 survey, 98% of them utilized NSAID prophylaxis and 62% pancreatic duct stent prophylaxis in specific cases. In the 2020 survey, the use of NSAIDs (100%), pancreatic duct stents (78%), and intensive intravenous hydration (33%) increased among ERCPists. NSAID prophylaxis was the preferred prophylactic measure for all risk factors in the 2020 survey, except for ampullectomy, pancreatic duct contrast injection, and pancreatic duct cannulation, for which NSAID prophylaxis and pancreatic duct stent combined was equally favored or preferred.ConclusionRectal NSAIDs are the most applied post-ERCP pancreatitis prophylaxis in the Netherlands, followed by pancreatic duct stents and intensive intravenous hydration. Additionally, there is reason to believe that recent guideline updates and active research participation have led to increased prophylaxis implementation.

Timing of endoscopic retrograde cholangiopancreatography in acute biliary pancreatitis without cholangitis: a nationwide inpatient cohort study.

Project description:BackgroundThe timing of endoscopic retrograde cholangiopancreatography (ERCP) in patients with acute biliary pancreatitis without cholangitis is unclear. We accessed a national database to analyze the outcomes of urgent (<24 h) and early (24-72 h) ERCP in this cohort.MethodsThe cohort was extracted from the Nationwide Inpatient Sample database. Hospital ERCP volumes were generated using unique hospital identifiers. Multivariate regression modeling was used to analyze the predictors of urgent vs. early ERCP use, and to determine various outcome variables between the 2 cohorts.ResultsOverall, 105,433 admissions were evaluated. There was a significant rise in urgent ERCP performed over the study period. Older patients, males, patients with comorbidities, African American and Hispanic patient populations were less likely to receive urgent ERCP. High ERCP volume hospitals, teaching hospitals, and hospitals in the Midwest and West were more likely to perform urgent ERCP. There were no differences in mortality rates or complication rates between the 2 cohorts. However, there were significant differences in length of stay and healthcare cost analysis.ConclusionsThe increasing use of urgent ERCP did not result in a clinically significant benefit in terms of mortality, length of stay, or healthcare cost analysis. The use of urgent ERCP is also not uniform across various demographic and hospital cohorts. Urgent ERCP may be over-utilized, and it may be reasonable to perform ERCP in this patient population based on the physician's suspicion about the severity of disease.

Urgent endoscopic retrograde cholangiopancreatography is not superior to early ERCP in acute biliary pancreatitis with biliary obstruction without cholangitis.

Project description:Acute pancreatitis is a common diagnosis worldwide, with gallstone disease being the most prevalent cause (50%). The American College of Gastroenterology recommends urgent endoscopic retrograde cholangiopancreatography (ERCP) (within 24 h) for patients with biliary pancreatitis accompanied by cholangitis. Most international guidelines recommend that ERCP be performed within 72 h in patients with biliary pancreatitis and a bile duct obstruction without cholangitis, but the optimal timing for endoscopy is controversial. We investigated the optimal timing for ERCP in patients with biliary pancreatitis and a bile duct obstruction without cholangitis, and whether performing endoscopy within 24 h is superior to performing it after 24 h. We analyzed the clinical data of 505 patients with newly diagnosed acute pancreatitis, from January 1, 2005 to December 31, 2014. We divided the patients into two groups according to the timing of ERCP: < 24 h (urgent) and 24-72 h (early).Among the 505 patients, 73 were diagnosed with biliary pancreatitis and a bile duct obstruction without cholangitis. The mean age of the patients was 55 years (range: 26-90 years). Bile duct stones and biliary sludge were identified on endoscopy in 45 (61.6%) and 11 (15.0%) patients, respectively. The timing of ERCP within 72 h was not associated with ERCP-related complications (P = 0.113), and the total length of hospital stay was not different between urgent and early ERCP (5.9 vs. 5.7 days, P = 0.174). No significant differences were found in total length of hospitalization or procedural-related complications, in patients with biliary pancreatitis and a bile duct obstruction without cholangitis, according to the timing of ERCP (< 24 h vs. 24-72 h).

Role of Somatostatin in Preventing Post-endoscopic Retrograde Cholangiopancreatography (ERCP) Pancreatitis: An Update Meta-analysis.

Project description:Background: Acute pancreatitis is the most common serious complication of endoscopic retrograde cholangiopancreatography (ERCP). Although, somatostatin (SOM) has been used in the prevention of post-ERCP pancreatitis (PEP), the efficacy of SOM remains inconsistent. Methods: Electronic databases, including PubMed/MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), and the Science Citation Index were searched to retrieve relevant studies. Details of the study population, including patients' characteristics, sample size, regimen of drug administration and incidence of PEP, hyperamylasemia and abdominal pain were extracted by two investigators. Data were analyzed with Review Manager 5.3 software. Results: Eleven randomized controlled trials, enrolling a total of 4192 patients, were included in the meta-analysis. After data were pooled, we observed decreased incidence of ERCP-induced outcomes, such as PEP (RR = 0.63, 95% CI: 0.40, 0.98; P = 0.04) and hyperamylasemia (RR = 0.75, 95% CI: 0.66, 0.84; P < 0.001) in patients treated with SOM than those with placebo. Subgroup analysis by ethnicity found decreased incidence of PEP and hyperamylasemia in Asia only. Subgroup analysis by treatment schedule and dosage revealed decreased incidence of PEP and hyperamylasemia when SOM were treated with a single bolus or long-term infusion, or at dose above 3000 μg. We did not observed efficacy of SOM on abdominal pain in pooled or subgroup analysis. Conclusion: This meta-analysis of patients undergoing ERCP showed reduced incidence of PEP and hyperamylasemia when SOM was administrated with single bolus, long-term infusion, or high dosage. More data are needed to confirm our findings.

Identification of risk factors for post-endoscopic retrograde cholangiopancreatography pancreatitis in a high volume center.

Project description:Background/objectivesPancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP). Several patients´ or procedure related risk factors for post-ERCP pancreatitis (PEP) have been suggested. The aim of this study was to validate the risk factors for PEP in a high-volume center.MethodsAll patients undergoing first time ERCP at a tertiary referral center between December 2010 and October 2013 were retrospectively included. PEP was defined according to the Atlanta Classification.Results404 patients were included in the final analysis. The risk to develop PEP was increased in patients after inadvertent cannulation of the pancreatic duct (odds ratio 7.468 (2.792–19.975); p<0.001), which occurred in 37.4% of the patients. Inadvertent cannulation occurred significantly more frequently in patients with difficult cannulation of the papilla duodeni major (odds ratio 7.3; p<0.001).ConclusionInadvertent cannulation of the pancreatic duct is a procedure related risk factor for PEP. Measurements on preventing inadvertent cannulation of the pancreatic duct should be established and studies on prophylactic measurements should focus particularly on patients with inadvertent cannulation of the pancreatic duct.

Naproxen, isosorbide dinitrate and co-administration cannot prevent post-endoscopic retrograde cholangiopancreatography pancreatitis: Randomized controlled trial.

Project description:Backgrounds/Aims:Acute pancreatitis is the most widespread complication of endoscopic retrograde cholangiopancreatography. Here, we investigated the efficacy of rectal suppository naproxen, sublingual isosorbide dinitrate and their co-administration in the prevention of post-ERCP pancreatitis. Methods:This double-blind randomized clinical trial carried out from June 2015 to February 2016 at the Gastrointestinal and Liver Diseases Research Center in Rasht, Iran. A total of 585 patients were selected from candidates for diagnostic or therapeutic ERCP by using the simple sampling method. Patients divided into three groups. Group A received 500 mg naproxen, group B took 5 mg isosorbide dinitrate, and group C was co-administrated both agents before ERCP. The primary outcome measure was the development of pancreatitis onset of pain in the upper abdomen and increase of serum amylase activity more than 3 times over the upper normal limit (60-100 IU/L) within first the 24 h post-ERCP. Results:Totally, 80 patients developed PEP included 29 (4.9%), 24 (4.1%), and 27 (4.6%) patients in groups A, B, and C, respectively (p=0.845). Longer ERCP time (p=0.041), using diazepam (p=0.033), a higher number of pancreatic ducts cannulation (p?0.001), pancreatic duct injection (p=0.013), and using pancreatic stent (p=0.004) were the predisposing factors for PEP. Conclusions:Our findings indicated that prophylactic naproxen suppository or isosorbide dinitrate sublingually or co-administration had no significant difference in the prevention and severity of PEP, however, enhancing the endoscopist's skills can be effective. Departments and educational hospitals should develop their assessment and quality assurance measures for the training of fellows' not only technical training but also an understanding of the diagnostic and therapeutic roles of the procedure.
