Abstract

This document is intended to educate readers on the rates and predictors of adverse events in adult patients who undergo endoscopic ultrasound (EUS). Our goal is to assist endoscopists in providing accurate, evidence-based, and up-to-date information on the rates of adverse events to patients, caretakers, and trainees. The information provided should not be construed as encouraging or discouraging any particular treatment or technique. Clinical decision-making in any specific case involves a personalized and thorough analysis of the patient’s condition, available courses of action, local expertise, and the patient’s values and preferences. Therefore, certain clinical considerations could lead an endoscopist to take a course of action that varies from the guidance in this document. This document is an update of a previous guideline prepared by the Standards of Practice Committee of the American Society for Gastrointestinal Endoscopy in 2013.1Early D.S. Acosta R.D. Chandrasekhara V. et al.Adverse events associated with EUS and EUS with FNA.Gastrointest Endosc. 2013; 77: 839-843Abstract Full Text Full Text PDF PubMed Scopus (129) Google Scholar EUS has become a frequently used diagnostic and therapeutic modality used by endoscopists in the United States and throughout the world. Yearly use of EUS in the United States has consistently increased, supplanting the volume of ERCPs performed.2Peery A.F. Crockett S.D. Murphy C.C. et al.Burden and cost of gastrointestinal, liver, and pancreatic diseases in the United States: update 2018.Gastroenterology. 2019; 156: 254-272Abstract Full Text Full Text PDF PubMed Google Scholar Indications for EUS are broad and include the diagnosis and staging of GI and non-GI malignancies, assessment of pancreatobiliary targets, and sampling and drainage of cystic structures. In addition, several EUS-guided procedures have become widely accepted in recent years, including management of pancreatic fluid collections (PFCs), EUS-guided biliary and gallbladder drainage (EUS-BD and EUS-GD, respectively), celiac plexus blockade and neurolysis (CPB/CPN), variceal management, and EUS-guided gastroenterostomy (EUS-GE) or enteroenterostomy. Given the associated skill profile including technical proficiency, image recognition, and cognitive skills, additional training beyond a GI fellowship is generally required to perform EUS safely. To optimize the overall quality of EUS procedures, evidence-based indicators specific to the performance of EUS have been established.3Wani S. Wallace M.B. Cohen J. et al.Quality indicators for EUS.Am J Gastroenterol. 2015; 110: 102-113Crossref PubMed Google Scholar The adverse event (AE) profile specifically associated with the performance of EUS must similarly be considered separately from those associated with other luminal endoscopic procedures. This document summarizes available evidence on AEs associated with EUS and EUS-guided procedures in adult patients. A comprehensive electronic database search was executed in conjunction with an expert healthcare librarian (M.V.) and was composed of 5 parts, each designed to capture specific AEs associated with (1) routine EUS with or without FNA or fine-needle biopsy sampling (FNB), (2) EUS with PFC management, (3) EUS-BD and EUS-GD, (4) EUS with CPB or CPN, and (5) other EUS-guided techniques including variceal management and EUS-GE. AEs related to sedation and/or anesthesia, which are not specific to EUS, were not reviewed in this document. An English-language search, whose full details are provided in Appendix 1 (available online at www.giejournal.org), was performed in PubMed, MEDLINE (Ovid), MEDLINE (EBSCO), the Excerpta Medica Database, Web of Science, the Cochrane Central Registry of Controlled Trials, and the Cumulative Index of Nursing and Allied Health Literature for citations published between January 1, 2000 to December 7, 2020 (deemed a suitable search period to reflect contemporary experiences with EUS). All citations initially identified were imported into DistillerSR (Evidence Partners, Ottawa, Ontario, Canada), and all duplicates were removed. In parallel, bibliographies of selected citations were searched, ad hoc supplementary PubMed database searches were performed, and experts were consulted for any potential studies not identified by the electronic strategy. Given that this document was not designed to answer any specific comparative questions but rather to update the state of knowledge on EUS-associated AEs, specific screening eligibility criteria were not required to be met for a study to be considered for inclusion. This decision was made given the variable amounts and quality of evidence available describing each separate EUS-guided technique. However, studies were generally considered for inclusion based on design in the descending order of the following: meta-analyses, randomized controlled trials (RCTs), prospective observational studies, retrospective observational studies, and case series or reports, with study size, study quality, and study recency factoring into the decision. In the first round of screening, we screened titles and abstracts and assigned studies to a designation of “possibly include” or “exclude” considering the above criteria. Any abstract labeled with the decision to possibly include the citation resulted in the study being included in the second round. After the title and abstract screen, we made the decision on whether to cite studies included in the second round in the final review document based on the above criteria. Data on AEs were then extracted from the full-text studies selected for inclusion and presented according to each EUS-guided procedure type. Of 3619 initial citations identified from the electronic search, 1284 were for routine EUS, 556 for EUS with drainage and/or stenting of PFCs, 623 for EUS-BD and EUS-GD, 475 for EUS with CPB or CPN, and 681 for EUS-guided variceal management, EUS-GE, and other miscellaneous and novel EUS-guided procedures. A review of the evidence for each major AE type is provided below, with an overview of estimated AE rates provided in Table 1. Predictors of overall and/or specific AEs were also considered and reported wherever possible.Table 1Summary of estimated common adverse event ranges for EUS-guided proceduresEUS-guided procedure typePerforation (%)Hemorrhage (%)Infection (%)Other/specific (%)Risk factors for adverse eventsRoutine EUS (with or without FNA/fine-needle biopsy sampling).02-.085Wang K.X.
