Incidence, severity, and mortality of post-ERCP pancreatitis: an updated systematic review and meta-analysis of 145 randomized controlled trials. Gastrointest Endosc 2023; 98:1-6.e12. [PMID: 37004815 DOI: 10.1016/j.gie.2023.03.023] [Citation(s) in RCA: 15] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2021] [Revised: 03/01/2023] [Accepted: 03/21/2023] [Indexed: 04/04/2023]
Abstract
BACKGROUND AND AIMS The incidence, severity, and mortality of post-ERCP pancreatitis (PEP) largely remain unknown with changing trends in ERCP use, indication, and techniques. We sought to determine the incidence, severity, and mortality of PEP in consecutive and high-risk patients based on a systemic review and meta-analysis of patients in placebo and no-stent arms of randomized control trials (RCTs). METHODS The MEDLINE, Embase, and Cochrane databases were searched from the inception of each database to June 2022 to identify full-text RCTs evaluating PEP prophylaxes. The incidence, severity, and mortality of PEP from the placebo or no-stent arms of RCTs were recorded for consecutive and high-risk patients. A random-effects meta-analysis for a proportions model was used to calculate PEP incidence, severity, and mortality. RESULTS One hundred forty-five RCTs were found with 19,038 patients in the placebo or no-stent arms. The overall cumulative incidence of PEP was 10.2% (95% confidence interval [CI], 9.3-11.3), predominantly among the academic centers conducting such RCTs. The cumulative incidences of severe PEP and mortality were .5% (95% CI, .3-.7) and .2% (95% CI, .08-.3), respectively, across 91 RCTs with 14,441 patients. The cumulative incidences of PEP and severe PEP were 14.1% (95% CI, 11.5-17.2) and .8% (95% CI, .4-1.6), respectively, with a mortality rate of .2% (95% CI, 0-.3) across 35 RCTs with 3733 patients at high risk of PEP. The overall trend for the incidence of PEP among patients randomized to placebo or no-stent arms of RCTs has remained unchanged from 1977 to 2022 (P = .48). CONCLUSIONS The overall incidence of PEP is 10.2% but is 14.1% among high-risk patients based on this systematic review of placebo or no-stent arms of 145 RCTs; this rate has not changed between 1977 and 2022. Severe PEP and mortality from PEP are relatively uncommon.

[PMID: 31413535 PMCID: PMC6689803 DOI: 10.3748/wjg.v25.i29.4019] [Citation(s) in RCA: 29] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2019] [Revised: 05/19/2019] [Accepted: 07/03/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Post endoscopic retrograde cholangiopancreatography (ERCP) is comparatively complex application. Researchers has been investigated prevention of post-ERCP pancreatitis (PEP), since it has been considered to be the most common complication of ERCP. Although ERCP can lead various complications, it can also be avoided.
AIM To study the published evidence and systematically review the literature on the prevention and treatment for PEP.
METHODS A systematic literature review on the prevention of PEP was conducted using the electronic databases of ISI Web of Science, PubMed and Cochrane Library for relevant articles. The electronic search for the review was performed by using the search terms “Post endoscopic retrograde cholangiopancreatography pancreatitis” AND “prevention” through different criteria. The search was restricted to randomized controlled trials (RCTs) performed between January 2009 and February 2019. Duplicate studies were detected by using EndNote and deleted by the author. PRISMA checklist and flow diagram were adopted for evaluation and reporting. The reference lists of the selected papers were also scanned to find other relevant studies.
RESULTS 726 studies meeting the search criteria and 4 relevant articles found in the edited books about ERCP were identified. Duplicates and irrelevant studies were excluded by screening titles and abstracts and assessing full texts. 54 studies were evaluated for full text review. Prevention methods were categorized into three groups as (1) assessment of patient related factors; (2) pharmacoprevention; and (3) procedural techniques for prevention. Most of studies in the literature showed that young age, female gender, absence of chronic pancreatitis, suspected Sphincter of Oddi dysfunction, recurrent pancreatitis and history of previous PEP played a crucial role in posing high risks for PEP. 37 studies designed to assess the impact of 24 different pharmacologic agents to reduce the development of PEP delivered through various administration methods were reviewed. Nonsteroidal anti-inflammatory drugs are widely used to reduce risks for PEP. Rectal administration of indomethacin immediately prior to or after ERCP in all patients is recommended by European Society for Gastrointestinal Endoscopy guidelines to prevent the development of PEP. The majority of the studies reviewed revealed that rectally administered indomethacin had efficacy to prevent PEP. Results of the other studies on the other pharmacological interventions had both controversial and promising results. Thirteen studies conducted to evaluate the efficacy of 4 distinct procedural techniques to prevent the development of PEP were reviewed. Pancreatic Stent Placement has been frequently used in this sense and has potent and promising benefits in the prevention of PEP. Studies on the other procedural techniques have had inconsistent results.
CONCLUSION Prevention of PEP involves multifactorial aspects, including assessment of patients with high risk factors for alternative therapeutic and diagnostic techniques, administration of pharmacological agents and procedural techniques with highly precise results in the literature.

Abstract
Acute pancreatitis (AP) accounts for over 230 000 US and 28 000 UK hospital admissions annually. Abdominal pain is the most common presenting symptom in AP but may not reflect severity. The clinical challenge is identifying the 20% of patients in whom AP will be severe. We summarise the common aetiologies, the risk stratification strategies including the simplified Bedside Index for Severity in Acute Pancreatitis, acute management approaches in the initial presentation setting, conditions for using advance imaging and opinions on antibiotic use. Some warning signs of impending complications are also discussed.

The Interplay between Inflammation, Coagulation and Endothelial Injury in the Early Phase of Acute Pancreatitis: Clinical Implications. Int J Mol Sci 2017; 18:E354.

Abstract
Acute pancreatitis (AP) is an inflammatory disease with varied severity, ranging from mild local inflammation to severe systemic involvement resulting in substantial mortality. Early pathologic events in AP, both local and systemic, are associated with vascular derangements, including endothelial activation and injury, dysregulation of vasomotor tone, increased vascular permeability, increased leukocyte migration to tissues, and activation of coagulation. The purpose of the review was to summarize current evidence regarding the interplay between inflammation, coagulation and endothelial dysfunction in the early phase of AP. Practical aspects were emphasized: (1) we summarized available data on diagnostic usefulness of the markers of endothelial dysfunction and activated coagulation in early prediction of severe AP; (2) we reviewed in detail the results of experimental studies and clinical trials targeting coagulation-inflammation interactions in severe AP. Among laboratory tests, d-dimer and angiopoietin-2 measurements seem the most useful in early prediction of severe AP. Although most clinical trials evaluating anticoagulants in treatment of severe AP did not show benefits, they also did not show significantly increased bleeding risk. Promising results of human trials were published for low molecular weight heparin treatment. Several anticoagulants that proved beneficial in animal experiments are thus worth testing in patients.

Abstract
Post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP), and not uncommonly is the reason behind ERCP-related lawsuits. Patients at high risk for PEP include young women with abdominal pain, normal liver tests, and unremarkable imaging. Procedure-related factors include traumatic and persistent cannulation attempts, multiple injections of the pancreatic duct, pancreatic sphincterotomy, and, possibly, use of precut sphincterotomy. Aggressive hydration, use of rectal indomethacin, and prophylactic pancreatic stenting can diminish the risk (and likely severity) of PEP. Though hugely beneficial, these measures do not supersede careful patient selection and technique.

Abstract
BACKGROUND Data regarding the incidence and severity of post-ERCP pancreatitis (PEP) are primarily from nonrandomized studies. OBJECTIVE To determine the incidence, severity, and mortality of PEP from a systematic review of the placebo or no-stent arms of randomized, controlled trials (RCTs). DESIGN MEDLINE, EMBASE, and Cochrane databases were searched to identify RCTs evaluating the efficacy of drugs and/or pancreatic stents to prevent PEP. SETTING Systematic review of patients enrolled in RCTs evaluating agents for PEP prophylaxis. PATIENTS Patients in the placebo or no-stent arms of the RCTs INTERVENTION ERCP. MAIN OUTCOME MEASUREMENTS Incidence, severity, and mortality of PEP. RESULTS There were 108 RCTs with 13,296 patients in the placebo or no-stent arms. Overall, the PEP incidence was 9.7% and the mortality rate was 0.7%. Severity of PEP was reported for 8857 patients: 5.7%, 2.6%, and 0.5% of cases were mild, moderate, and severe, respectively. The incidence of PEP in 2345 high-risk patients was 14.7% and the severity of PEP was mild, moderate, and severe in 8.6%, 3.9%, and 0.8%, respectively, with a 0.2% mortality rate. The incidence of PEP was 13% in North American RCTs compared with 8.4% in European and 9.9% in Asian RCTs. ERCPs conducted before and after 2000 had a PEP incidence of 7.7% and 10%, respectively. LIMITATIONS Difference in PEP risk among patients in the included RCTs. CONCLUSION The incidence of PEP and severe PEP is similar in high-risk patients and the overall cohort. Discrepancies in the incidence of PEP across geographic regions require further study.

Abstract
Post-procedure pancreatitis is the most common complication of endoscopic retrograde cholangio pancreatography (ERCP) and carries a high morbidity and mortality occurring in at least 3%-5% of all procedures. We reviewed the available literature searching for "ERCP" and "pancreatitis" and "post-ERCP pancreatitis". in PubMed and Medline. This review looks at the diagnosis, risk factors, causes and methods of preventing post-procedure pancreatitis. These include the evidence for patient selection, endoscopic techniques and pharmacological prophylaxis of ERCP induced pancreatitis. Selecting the right patient for the procedure by a risk benefits assessment is the best way of avoiding unnecessary ERCPs. Risk is particularly high in young women with sphincter of Oddi dysfunction (SOD). Many of the trials reviewed have rather few numbers of subjects and hence difficult to appraise. Meta-analyses have helped screen for promising modalities of prophylaxis. At present, evidence is emerging that pancreatic stenting of patients with SOD and rectally administered nonsteroidal anti-inflammatory drugs in a large unselected trial reduce the risk of post-procedure pancreatitis. A recent meta-analysis have demonstrated that rectally administered indomethecin, just before or after ERCP is associated with significantly lower rate of pancreatitis compared with placebo [OR = 0.49 (0.34-0.71); P = 0.0002]. Number needed to treat was 20. It is likely that one of these prophylactic measures will begin to be increasingly practised in high risk groups.

Abstract
BACKGROUND A previous study suggested that ulinastatin effectively prevented post-ERCP pancreatitis (PEP) and hyperenzymemia (PEH) in patients at average risk. In experimental models, risperidone, a selective serotonin 2A antagonist, ameliorated acute pancreatitis. We assessed the effect of risperidone combined with ulinastatin for the prevention of PEP in high-risk patients. METHODS In a multicenter, randomized, controlled, phase II trial, patients undergoing therapeutic ERCP were randomly assigned to receive ulinastatin (150000 U) with or without risperidone (1 mg). A risperidone tablet was taken orally 30-60 min before ERCP and ulinastatin was administered intravenously for 10 min immediately prior to ERCP. The primary end point was the incidence of PEP; secondary end points were PEH severity and enzyme levels (amylase, pancreatic amylase, lipase). RESULTS A total of 226 patients (113 per group) were included in the study. Six patients in the risperidone + ulinastatin group and ten patients in the ulinastatin group developed pancreatitis (5.3 vs. 8.8 %, p = 0.438). The incidence of moderate/severe PEP was lower in the risperidone + ulinastatin group (1.8 %) than in the ulinastatin group (4.4 %), but this difference was not significant. Although the incidence of PEH did not differ significantly, post-ERCP levels of all pancreatic enzymes were significantly lower in the risperidone + ulinastatin group. CONCLUSIONS Prophylactic oral risperidone administration in combination with ulinastatin did not reduce the incidence and severity of PEP in high-risk patients as compared with ulinastatin alone. However, risperidone showed an additive effect with ulinastatin, reducing serum pancreatic enzyme levels.

Abstract
BACKGROUND Udenafil, a phosphodiesterase-5 inhibitor, may decrease sphincter of Oddi tone and allow efficient cannulation. OBJECTIVE To determine whether prophylactic udenafil reduces the rates of occurrence of post-ERCP pancreatitis. DESIGN Prospective, randomized, double-blind, placebo-controlled, multicenter study. SETTING Three academic medical centers. PATIENTS From November 2008 to November 2010, a total of 278 patients who underwent ERCP were analyzed. INTERVENTION ERCP. MAIN OUTCOME MEASUREMENT Rate of post-ERCP pancreatitis. RESULTS Demographic features, indications for ERCP, and therapeutic procedures were similar in each group. The overall rate of pancreatitis was 7.9% (22/278). There was no significant difference in the rate (8.0% [11/137] vs 7.8% [11/141], P = .944) and severity of post-ERCP pancreatitis between the udenafil and placebo groups. Severe pancreatitis developed in 1 patient in the placebo group. On both univariate and multivariate analyses, age 40 years or younger, suspected sphincter of Oddi dysfunction, complete pancreatic duct opacification, and failed cannulation were associated with post-ERCP pancreatitis. Only mild udenafil-related complications occurred, including flushing (n = 3) and headache (n = 3). LIMITATIONS Unselected patient group, overestimation of the rate of pancreatitis in the placebo group. CONCLUSION Udenafil was not effective for prevention of post-ERCP pancreatitis in this study.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) is an important tool for the diagnosis and treatment of pancreatobiliary disease. Acute pancreatitis (AP) is the most common complication of ERCP. The pathogenesis of post-ERCP AP has not been completely elucidated. Recent studies suggest that inflammatory cytokines play an important role in the evolution of AP from mild to severe form. Identification of specific proinflammatory markers that can rapidly and reliably predict the progression of post-ERCP pancreatitis has been a major focus of research. Attempts to block the inflammatory cascade have been carried out by using an anti-inflammatory cytokine in some clinical trials. In this article, we will review the recent advances in understanding the role of cytokines in the pathogenesis of post-ERCP AP.

Abstract
Acute pancreatitis is a common cause for hospitalization that carries a substantial burden of disease in the United States and worldwide. Recent reports have encompassed a wide array of topics including new insights into the acinar cell pH microenvironment, signal pathways for acinar cell fate, and the innate immune response. Clinical researchers have reported new methods to assess disease severity, innovative techniques for management of local complications, the importance of early recognition of pancreatic or extrapancreatic infection, and prevention of disease recurrence. Recent data also suggest that specialized centers may be of benefit for the management of severe acute pancreatitis. This review summarizes a number of recent advances in basic and clinical science with an emphasis on findings that are relevant to clinicians who manage patients with acute pancreatitis.

Abstract
The aim of this article is to review the literature regarding post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. We searched for and evaluated all articles describing the diagnosis, epidemiology, pathophysiology, morbidity, mortality and prevention of post-ERCP pancreatitis (PEP) in adult patients using the PubMed database. Search terms included endoscopic retrograde cholangiopancreatography, pancreatitis, ampulla of vater, endoscopic sphincterotomy, balloon dilatation, cholangiography, adverse events, standards and utilization. We limited our review of articles to those published between January 1, 1994 and August 15, 2009 regarding human adults and written in the English language. Publications from the reference sections were reviewed and included if they were salient and fell into the time period of interest. Between the dates queried, seventeen large (> 500 patients) prospective and four large retrospective trials were conducted. PEP occurred in 1%-15% in the prospective trials and in 1%-4% in the retrospective trials. PEP was also reduced with pancreatic duct stent placement and outcomes were improved with endoscopic sphincterotomy compared to balloon sphincter dilation in the setting of choledocholithiasis. Approximately 34 pharmacologic agents have been evaluated for the prevention of PEP over the last fifteen years in 63 trials. Although 22 of 63 trials published during our period of review suggested a reduction in PEP, no pharmacologic therapy has been widely accepted in clinical use in decreasing the development of PEP. In conclusion, PEP is a well-recognized complication of ERCP. Medical treatment for prevention has been disappointing. Proper patient selection and pancreatic duct stenting have been shown to reduce the complication rate in randomized clinical trials.
