Abstract
INTRODUCTION Point of use (POU) treatment is a critical first step of medical device reprocessing. Reusable instruments and flexible endoscopes require a minimum of terminal sterilization or high-level disinfection, neither of which can be guaranteed if POU is performed incorrectly. Compliance considerations for POU include hospital accreditation readiness, unique austere surgical mission requirements, and the transition of future conflict towards Large Scale Combat Operations. This integrative review aims to describe POU for reusable instruments and endoscopes, and extrapolate implications for Military Health System policies and future considerations. MATERIALS AND METHODS The authors performed an integrative review and comprehensive literature search in PubMed and CINAHL with the keywords "point of use," "point of use cleaning," "POU," "instrument," "high-level disinfection," "endoscope," and "clean." Articles were limited to "English" and "human" from 2017 to 2023. The authors also performed a thorough review of the Defense Health Agency and service-specific doctrine, as well as national guidelines regarding POU adherence. RESULTS The literature review yielded 18 articles that discussed the transport and reprocessing of reusable medical devices. Regulatory standards and national guidelines were used to supplement the literature. Seventeen evidence-based criteria were extrapolated from the literature to generate two step-by-step guides for the POU treatment of endoscopes and reusable instruments (Tables I and II). Despite increased morbidity and mortality rates linked to inadequate device reprocessing, compliance with POU procedures remains low. Barriers to practice included complex POU processes, intricately designed surgical instruments and endoscopes, lack of healthcare worker (HCW) knowledge and competency, and inadequate or ambiguously written policies. Training, competency assessments, and clearly written policies and procedures can be cost-effective, evidence-based, and feasible solutions. CONCLUSION Completing POU treatment is critical to a successful surgical mission in both the hospital and austere environment. Implications to practice include implementing evidence-based POU programs that improve patient outcomes and readiness while decreasing costs.

Increasing Antibiotic-Resistant Infections With Inpatient Endoscopic Retrograde Cholangioscopies (ERCP) Is Associated With Higher Mortality in the United States: A Cross-sectional Cohort Study. J Clin Gastroenterol 2024; 58:487-493. [PMID: 37339277 DOI: 10.1097/mcg.0000000000001874] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Accepted: 05/11/2023] [Indexed: 06/22/2023]
Abstract
GOALS This study aims to investigate associated mortality with inpatient endoscopic retrograde cholangiopancreatography (ERCP) with and without resistant infections. The co-primary objective compares frequencies of inpatient ERCP with resistant infections to overall hospitalizations with resistant infections. BACKGROUND The risks of inpatient antibiotic-resistant organisms are known, but the associated mortality for inpatient ERCP is unknown. We aim to use a national database of hospitalizations and procedures to understand trends and mortality for patients with antibiotic-resistant infections during inpatient ERCP. STUDY The largest publicly available all-payer inpatient database in the United States (National Inpatient Sample) was used to identify hospitalizations associated with ERCPs and antibiotic-resistant infections for MRSA, VRE, ESBL, and MDRO. National estimates were generated, frequencies were compared across years, and multivariate regression for mortality was performed. RESULTS From 2017 to 2020, national weighted estimates of 835,540 inpatient ERCPs were generated, and 11,440 ERCPs had coincident resistant infections. Overall resistant infection, MRSA, VRE, and MDRO identified at the same hospitalization of inpatient ERCPs were associated with higher mortality (OR CI(95%): Overall: 2.2(1.77-2.88), MRSA: 1.90 (1.34-2.69), VRE: 3.53 (2.16-5.76), and MDRO: 2.52 (1.39-4.55)). While overall hospitalizations with resistant infections have been decreasing annually, there has been a yearly increase in admissions requiring ERCPs with simultaneous resistant infections ( P =0.001-0.013), as well as infections with VRE, ESBL, and MDRO ( P =0.001-0.016). Required Research Practices for Studies Using the NIS scoring was 0, or the most optimal. CONCLUSIONS Inpatient ERCPs have increasing coincident resistant infections and are associated with higher mortality. These rising infections during ERCP highlight the importance of endoscopy suite protocols and endoscopic infection control devices.

Kremer T, Rowan NJ, McDonnell G. A proposed cleaning classification system for reusable medical devices to complement the Spaulding classification. J Hosp Infect 2024; 145:88-98. [PMID: 38103694 DOI: 10.1016/j.jhin.2023.11.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 11/17/2023] [Accepted: 11/22/2023] [Indexed: 12/19/2023]
Abstract
A central tenet in infection prevention is application of the Spaulding classification system for the safe use of medical devices. Initially defined in the 1950s, this system defines devices and surfaces as being critical, semi-critical or non-critical depending on how they will be used on a patient. Different levels of antimicrobial treatment, defined as various levels of disinfection or sterilization, are deemed appropriate to reduce patient risk of infection. However, a focus on microbial inactivation is insufficient to address this concern, which has been particularly highlighted in routine healthcare facility practices, emphasizing the underappreciated importance of cleaning and achieving acceptable levels of cleanliness. A deeper understanding of microbiology has evolved since the 1950s, which has led to re-evaluation of the Spaulding classification along with a commensurate emphasis on achieving appropriate cleaning. Albeit underappreciated, cleaning has always been important as the presence of residual materials on surfaces can interfere with the efficacy of the antimicrobial process to inactivate micro-organisms, as well as other risks to patients including device damage, malfunction and biocompatibility concerns. Unfortunately, this continues to be relevant, as attested by reports in the literature on the occurrence of device-related infections and outbreaks due to failures in processing expectations. This reflects, in part, increasing sophistication in device features and reuse, along with commensurate manufacturer's instructions for use. Consequently, this constitutes the first description and recommendation of a new cleaning classification system to complement use of the traditional Spaulding definitions to help address these modern-day technical and patient risk challenges. This quantitative risk-based classification system highlights the challenge of efficient cleaning based on the complexity of device features present, as an isolated variable impacting cleaning. This cleaning classification can be used in combination with the Spaulding classification to improve communication of cleaning risk of a reusable medical device between manufacturers and healthcare facilities, and improve established cleaning practices. This new cleaning classification system will also inform future creation, design thinking and commensurate innovations for the sustainable safe reuse of important medical devices.

Abstract
BACKGROUND Transmission of infections via contaminated endoscopes is a common problem. Manual cleaning, using at least a detergent, is an important step in endoscope processing and should be performed as soon as possible to avoid drying of organic residues that might interfere with high-level disinfection and promote biofilm formation. AIM To assess the efficacy of two detergent-disinfectants, enzymatic and non-enzymatic, and of an enzymatic detergent used during the manual cleaning against a Klebsiella pneumoniae biofilm. METHODS A 24 h biofilm statically formed in a Tygon tube was exposed to detergent-disinfectants at 20 °C and 35 °C for 10 mn, and to enzymatic detergent at 45 °C for 60 mn. The logarithmic reduction in bacteria in the Tygon tube and the number of bacteria in the product supernatant were calculated. FINDINGS Biofilm formation was reproducible between assays. After exposure to detergent-disinfectants, the logarithmic reduction was between 6.32 and 6.71 log10 cfu/cm2 in the Tygon tubes. No bacteria were found in their supernatants. Results in the detergent-disinfectant group were not affected by the exposure temperature or the addition of enzymes. No decrease in the bacterial load was observed in the Tygon tubes after exposure to the enzymatic detergent. Bacteria were found in its supernatant. CONCLUSION These results show the importance of the choice of products used during the manual cleaning phase. They also show the potential benefit of combining detergent and disinfectant activity to decrease the bacterial load during the manual cleaning step of endoscope processing.

Abstract
INTRODUCTION Single-use disposable duodenoscopes (SDD) have been developed to mitigate infectious risks related to reusable duodenoscopes. The aim of this study is to compare the safety and efficacy of the two available SDDs in the United States. METHODS We conducted a comparative study of 2 SDD in consecutive ERCP procedures performed by expert endoscopists from 9 academic centers. Performance ratings, procedure details, and adverse events were collected. RESULTS A total of 201 patients were included: 129 patients underwent ERCP with Exalt (mean age 63, Males- 66 (51%), 72 with aScope Duodeno (mean age 65, males=30 (42%). A majority of endoscopists had performed >2000 ERCPs in both groups (71% Exalt, 93% aScope Duodeno). Technical success was 92% in both groups (n=119 Exalt-group, n=66 aScope-Duodeno-group). The procedural complexity for the ERCP cases performed were: Grade 1: 35 cases (18%), Grade 2: 83 cases (41%), Grade 3: 65 cases (32%), and Grade 4: 18 cases (9%). Thirteen patients (10%) from the Exalt group and 16 patients (22%) from the aScope Duodeno group required conversion to a reusable duodenoscope. On a scale of 1 to 5, Exalt and aScope Duodeno, respectively, were rated: 2.31 versus 2.60 for location and visualization quality, 1.38 versus 1.57 for maneuverability based on papillary orientation, 1.48 versus 1.15 for suction/air control, and 2.31 versus 2.34 for elevator efficiency. None of the adverse events were related to the SDDs. CONCLUSIONS The 2 SDDs were comparable. Further ongoing enhancements to these devices will improve maneuverability and clinical effectiveness.

A review of Spaulding's classification system for effective cleaning, disinfection and sterilization of reusable medical devices: Viewed through a modern-day lens that will inform and enable future sustainability. THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 878:162976. [PMID: 36963674 DOI: 10.1016/j.scitotenv.2023.162976] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/10/2022] [Revised: 02/23/2023] [Accepted: 03/17/2023] [Indexed: 05/13/2023]
Abstract
Despite advances in medicine and innovations in many underpinning fields including disease prevention and control, the Spaulding classification system, originally proposed in 1957, remains widely used for defining the disinfection and sterilization of contaminated re-usable medical devices and surgical instruments. Screening PubMed and Scopus databases using a PRISMA guiding framework generated 272 relevant publications that were used in this review. Findings revealed that there is a need to evolve how medical devices are designed, and processed by cleaning, disinfection (and/or sterilization) to mitigate patient risks, including acquiring an infection. This Spaulding Classification remains in use as it is logical, easily applied and understood by users (microbiologists, epidemiologists, manufacturers, industry) and by regulators. However, substantial changes have occurred over the past 65 years that challenge interpretation and application of this system that includes inter alia emergence of new pathogens (viruses, mycobacteria, protozoa, fungi), a greater understanding of innate and adaptive microbial tolerance to disinfection, toxicity risks, increased number of vulnerable patients and associated patient procedures, and greater complexity in design and use of medical devices. Common cited examples include endoscopes that enable non- or minimal invasive procedures but are highly sophisticated with various types of materials (polymers, electronic components etc), long narrow channels, right angle and heat-sensitive components and various accessories (e.g., values) that can be contaminated with high levels of microbial bioburden and patient tissues after use. Contaminated flexible duodenoscopes have been a source of several significant infection outbreaks, where at least 9 reported cases were caused by multidrug resistant organisms [MDROs] with no obvious breach in processing detected. Despite this, there is evidence of the lack of attention to cleaning and maintenance of these devices and associated equipment. Over the last few decades there is increasing genomic evidence of innate and adaptive resistance to chemical disinfectant methods along with adaptive tolerance to environmental stresses. To reduce these risks, it has been proposed to elevate classification of higher-risk flexible endoscopes (such as duodenoscopes) from semi-critical [contact with mucous membrane and intact skin] to critical use [contact with sterile tissue and blood] that entails a transition to using low-temperature sterilization modalities instead of routinely using high-level disinfection; thus, increasing the margin of safety for endoscope processing. This timely review addresses important issues surrounding use of the Spaulding classification system to meet modern-day needs. It specifically addresses the need for automated, robust cleaning and drying methods combined with using real-time monitoring of device processing. There is a need to understand entire end-to-end processing of devices instead of adopting silo approaches that in the future will be informed by artificial intelligence and deep-learning/machine learning. For example, combinational solutions that address the formation of complex biofilms that harbour pathogenic and opportunistic microorganisms on the surfaces of processed devices. Emerging trends are addressed including future sustainability for the medical devices sector that can be enabled via a new Quintuple Helix Hub approach that combines academia, industry, healthcare, regulators, and society to unlock real world solutions.

Abstract
Esophagogastroduodenoscopy (EGD), endoscopic retrograde cholangiopancreatography (ERCP) and colonoscopy (CLN) come with a potential risk of pathogen transmission. Unfortunately, up to now data on the causes and the distribution of pathogens is rather sparse.We performed a systematic review of the medical literature using the Worldwide Outbreak Database, the PubMed, and Embase. We then checked so-retrieved articles for potential sources of the outbreak, the spectrum of pathogens, the attack rates, mortality and infection control measures.In total 73 outbreaks (EGD: 24, ERCP: 42; CLN: 7) got included. The corresponding attack rates were 3.5%, 7.1% and 12.8% and mortality rates were 6.3%, 12.7% and 10.0% respectively. EGD was highly associated with transmission of enterobacteria including a large proportion of multi-drug resistant strains. ERCP led primarily to transmission of non-fermenting gram-negative rods. The most frequent cause was human failure during reprocessing regardless of the type of endoscope.Staff working in the field of endoscopy should always be aware of the possibility of pathogen transmission in order to detect and terminate those events at the early most time point. Furthermore, proper ongoing education of staff involved in the reprocessing and maintenance of endoscopes is crucial. Single-use devices may be an alternative option and lower the risk of pathogen transmission, but on the downside may also increase costs and waste.

Abstract
BACKGROUND AND AIMS Greenhouse gases (GHGs) that trap heat in the atmosphere are composed of carbon dioxide (CO2), methane, nitrous oxide and fluorinated gases (synthetic hydrofluorocarbons, perfluorocarbons and nitrogen trifluoride). In the USA, the health sector accounts for 8.5% of total GHG emissions. The primary objective of this systematic review was to critically analyse the carbon emissions data from GI endoscopic activity. DESIGN The GI endoscopy carbon cycle was evaluated at preprocedural, intraprocedural and postprocedural levels. We performed a systematic literature search of articles published on these issues until 30 June 2022 and discussed these available data on endoscopy unit GHG carbon cycle, barriers to reduce GHG emissions and potential solutions. The inclusion criteria were any full-text articles (observational, clinical trials, brief communications, case series and editorials) reporting waste generation from GI endoscopy. Abstracts, news articles and conference proceedings were excluded. RESULTS Our search yielded 393 records in PubMed, 1708 in Embase and 24 in Google Scholar. After application of inclusion and exclusion factors, we focused on 9 fulllength articles in detail, only 3 of them were cross-sectional studies (all from the USA), the others reviews or position statements. Therefore, the quality of the studies could not be assessed due to heterogeneity in definitions and amount of emissions. CONCLUSIONS Recognition of carbon emissions generated by GI endoscopy activity is critical. Although multiple limitations exists for quantification of these emission, there is an urgent need for collecting proper data as well as examining novel methods for reduction of these emissions for a sustainable endoscopic practices in the future.

Abstract
OBJECTIVE Several clinical procedures utilize duodenoscopes, which are processed for reuse after the procedures are completed. However, infection outbreaks due to improper duodenoscope processing occur frequently. To address this, we aimed to assess the contamination rates of duodenoscopes after reprocessing in nonoutbreak settings. DESIGN AND SETTING Prospective study in 16 clinical sites in the United States. METHODS We sampled and cultured reprocessed duodenoscopes following the FDA/CDC/ASM guideline; "Duodenoscope Surveillance Sampling and Culturing - Reducing the Risks of Infection." High-concern (HC) organisms were those highly associated with disease, including gram-negative rods, Staphylococcus aureus, Staphylococcus lugdunensis, β-hemolytic Streptococcus, Enterococcus spp, and yeasts. We evaluated duodenoscopes with ≥1 CFU of organisms after reprocessing. The reprocessing environments were also sampled and cultured. RESULTS We assessed 859 newer-model (NM) duodenoscopes (TJF-Q180V) and 850 older-model (OM) duodenoscopes (TJF-160F/VF); of these, 35 NM samples (4.1%) and 56 OM samples (6.6%) were contaminated with HC organisms. We detected and classified the HC organisms as gastrointestinal (45.4%), human origin (16.7%), environmental (24.1%), waterborne (13.0%), and unidentified (0.9%). CONCLUSIONS We detected an overall HC contamination rate of 5.3% in nonoutbreak settings. Although the relationship between endoscopic contamination and the occurrence of infections remains unclear, attempts should continue to be made to further reduce contamination rates. Additional improvements to the manufacturer's instructions for use, human factors during the reprocessing procedure, ongoing training programs, cleanliness of reprocessing environments, and the design of the distal end of the duodenoscope should be considered.

Clinical and Endoscopic Consequences of Delay in Stent Exchange Procedures With ERCP During the Covid-19 Pandemic. SURGICAL LAPAROSCOPY, ENDOSCOPY & PERCUTANEOUS TECHNIQUES 2022; 32:714-719. [PMID: 36044333 DOI: 10.1097/sle.0000000000001090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Accepted: 06/28/2022] [Indexed: 12/15/2022]
Abstract
INTRODUCTION During the COVID-19 pandemic, elective endoscopic retrograde cholangiopancreatography (ERCP) procedures have been postponed as recommended by international guidelines. In this study, the results of biliary and pancreatic ERCP procedures that had to be postponed during the pandemic process were investigated. MATERIALS AND METHODS Forty-seven patients whose stent exchange procedures with ERCP were postponed between March 2020 and June 2020 due to the COVID-19 pandemic were included in the study. Patients were evaluated in 2 groups as delayed biliary procedures (n: 32) and delayed pancreatic procedures (n: 15). Clinical problems (biliary or pancreatic pain, itching, cholangitis, etc.) and technical problems encountered during the procedure (stent migration, abundant stone sludge in the bile ducts, etc.) were compared with 46 patients who could be treated without delay (39 interventions for the biliary system and seven interventions for the pancreas). FINDINGS Considering the procedures for the biliary system, there was no difference in age and sex between the groups. Although clinical problems in biliary procedures were more common in the group with delay than in those without delay, this difference was not significant (34% vs. 20%; P: 0.14). The technical problems encountered during the procedures in the group with delay were significantly higher than those without delay (21% vs. 2.5%; P: 0.019), with stent migration being the most common problem (n: 5). Age and sex did not differ in the patients who had pancreatic interventions with and without delay. The clinical problems that developed in the patients did not differ between the groups with and without delay (26% vs. 28%; P: 0.8). Although technical problems were encountered in 1 out of 15 patients in the group with delay, no technical problem was experienced in the group without delay (P: 0.68). CONCLUSION Postponing elective ERCP procedures for the biliary system not for the pancreatic system during the COVID-19 pandemic brings technical problems.

Abstract
BACKGROUND Biliary disease is common occurrence and can make up a large portion of the practice of a general surgeon. Choledocholithasis is a common entity amongst those with biliary disease. Although modern trends favor endoscopic retrograde cholangiopancreatography (ERCP) and other imaging modalities for the diagnosis and management of choledocholithiasis, laparoscopic common bile duct exploration (LCBDE) is likely underutilized. METHODS A literature summary utilizing a PUBMED search was performed to provide an up-to-date account regarding the latest data on LCBDE. A video identifying and explaining the critical components of a LBCDE procedure is provided. RESULTS LCBDE is an underutilized procedure which offers equivalent clinical outcomes compared with ERCP along with a shorter length of stay and reduced costs. LCBDE is also noted to be an effective option for common bile duct stones in the setting of altered anatomy, such as a Roux-en-Y gastric bypass. CONCLUSION Although modern trends favor ERCP and other imaging modalities for the diagnosis and management of choledocholithiasis, LCBDE is likely underutilized by surgeons. LCBDE can provide many benefits to patients including avoidance of additional procedures, shorter length of stay, higher success rates, and less costs. Out video should act is a guide for those surgeons interested in implementation LCBDE in their practice.

Abstract
BACKGROUND Death after endoscopy is rare, under-reported, and has variable causes. This study aimed to evaluate the incidence and causes of fatal endoscopic adverse events (AEs) across two academic medical centers and to identify patient-, procedure-, and sedation-related risk factors. METHODS This is a retrospective cohort study of fatal adverse events causally related to endoscopy at Denver Health Medical Center and the University of Colorado Hospital from 2011 to 2020. Fatal AEs were retrieved from the physician-reported database. Electronic medical records were then reviewed to determine medical history, procedure details, subsequent treatments, and time and cause of death. RESULTS From January 2011 to January 2020, 146,010 GI endoscopy procedures were performed. Median patient age was 70 [51-78] and 57% were male. Thirty-one deaths were identified, 28 of which were attributed to endoscopy, yielding a procedure-related fatality rate of 0.018%. Procedures included 11 EGDs, one colonoscopy, two flexible sigmoidoscopies, six ERCPs, seven upper EUS, and one PEG-J tube placement. Specific causes of death included aspiration in four patients (14%); cardiac arrest or myocardial infarction in seven patients (25%); perforation in nine patients (32%); bleeding in four patients (14%); cholangitis or sepsis without perforation in three patients (11%); and acute pancreatitis in one patient (3.6%). CONCLUSIONS Fatal endoscopic AEs were rare but tended to occur in older patients with major comorbidities. Most deaths occurred from aspiration pneumonia, cardiac arrest, or perforation-related sepsis within 1 week of the procedure.

Abstract
Over 17.7 million gastrointestinal (GI) endoscopic procedures are performed annually, contributing to 68% of all endoscopic procedures in the United States. Usually, endoscopic procedures are low risk, but adverse events may occur, including cardiopulmonary complications, bleeding, perforation, pancreatitis, cholangitis, and infection. Infections after the GI endoscopies most commonly result from the patient's endogenous gut flora. Although many studies have reported infection after GI endoscopic procedures, a true estimate of the incidence rate of post-endoscopy infection is lacking. In addition, the infection profile and causative organisms have evolved over time. In recent times, multi-drug-resistant microorganisms have emerged as a cause of outbreaks of endoscope-associated infections (EAI). In addition, lapses in endoscope reprocessing have been reported, with some but not all outbreaks in recent times. This systematic review summarizes the demographical, clinical, and management data of EAI events reported in the literature. A total of 117 articles were included in the systematic review, with the majority reported from North America and Western Europe. The composite infection rate was calculated to be 0.2% following GI endoscopic procedures, 0.8% following ERCP, 0.123% following non-ERCP upper GI endoscopic procedures, and 0.073% following lower GI endoscopic procedures. Pseudomonas aeruginosa was the most common culprit organism, followed by other Enterobacteriaceae groups of organisms and Gram-positive cocci. We have also elaborated different prevention methods such as antimicrobial prophylaxis, adequate sterilization methods for reprocessing endoscopes, periodic surveillance, and current evidence supporting their utilization. Finally, we discuss disposable endoscopes, which could be an alternative to reprocessing to minimize the chances of EAIs with their effects on the environmental and financial situation.

[PMID: 34847498 DOI: 10.1016/j.jphotobiol.2021.112367] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Revised: 11/12/2021] [Accepted: 11/17/2021] [Indexed: 02/07/2023]
Abstract
The present study proposes an innovative opto-chemical treatment using a basket-integrated optical device (BIOD) to disinfect mature bacterial biofilm on endoscope channels. A BIOD was designed to position an optical diffuser on the central axis of an endoscope channel and to distribute laser light concentrically to the bacterial biofilm on the channel surface. To apply thermal damage and oxidative stress to the bacterial biofilm, a low concentration of a crosslinking agent (glutaraldehyde ~0.5%) was combined with 808 nm infrared (IR) and 405 nm blue (BL) laser lights. The applied irradiances of IR and BL were 10 W/cm2 and 1.6 W/cm2 for Teflon channel model and 20 W/cm2 and 3.2 W/cm2 for a clinical model, respectively. Individual irradiation of either IR or BL for 180 s induced the maximum temperatures of 62 ± 2 °C and 53 ± 3 °C on the biofilm, respectively. The simultaneous opto-chemical treatment reduced a significant population of the bacterial biofilms (7.5-log10 for Staphylococcus aureus and 7.1-log10 for Pseudomonas aeruginosa), which were 2.9-fold and 3.9-fold higher than that of the standard treatment with 2% glutaraldehyde (GA) solution, respectively. The proposed opto-chemical disinfection method can help reduce multi-drug resistant bacteria and prevent cross-infection during the clinical usage of a flexible endoscope.

Abstract
BACKGROUND AND AIMS Expert endoscopists previously reported ERCP outcomes for the first commercialized single-use duodenoscope. We aimed to document usability of this device by endoscopists with different levels of ERCP experience. METHODS Fourteen "expert" (>2000 lifetime ERCPs) and 5 "less-expert" endoscopists performed consecutive ERCPs in patients without altered pancreaticobiliary anatomy. Outcomes included ERCP completion for the intended indication, rate of crossover to another endoscope, device performance ratings, and serious adverse events. RESULTS Two hundred ERCPs including 81 (40.5%) with high complexity (American Society for Gastrointestinal Endoscopy grades 3-4) were performed. Crossover rate (11.3% vs 2.5%, P = .131), ERCP completion rate (regardless of crossovers) (96.3% vs 97.5%, P = .999), median ERCP completion time (25.0 vs 28.5 minutes, P = .130), mean cannulation attempts (2.8 vs 2.8, P = .954), and median overall satisfaction with the single-use duodenoscope (8.0 vs 8.0 [range, 1.0-10.0], P = .840) were similar for expert versus less-expert endoscopists, respectively. The same metrics were similar by procedural complexity except for shorter median completion time for grades 1 to 2 versus grades 3 to 4 (P < .001). Serious adverse events were reported in 13 patients (6.5%). CONCLUSIONS In consecutive ERCPs including high complexity procedures, endoscopists with varying ERCP experience had good procedural success and reported high device performance ratings.

World J Clin Cases 2021; 9:8404-8412. [PMID: 34754849 PMCID: PMC8554445 DOI: 10.12998/wjcc.v9.i28.8404] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Revised: 07/22/2021] [Accepted: 08/30/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The coronavirus disease 2019 (COVID-19) outbreak has markedly influenced the endoscopic patterns. Endoscopic retrograde cholangiopancreatography (ERCP) is an essential technique for pancreatobiliary disease but increases the risk of exposure to the virus-containing body fluid; however, the impact of COVID-19 on ERCP is unknown.
AIM To compare the number of endoscopic activities and to analyze the clinical outcomes of ERCPs before and during the COVID-19 outbreak in Daegu, South Kore.
METHODS This retrospective cohort study included patients aged ≥ 18 years who underwent ERCP between February 18 and March 28, 2020, at a tertiary hospital. ERCP indications and endoscopic details were compared with those from the same period in 2018 and 2019 as control groups.
RESULTS Of the 269 ERCP procedures, 113 (42.0%) cases were performed as emergency procedures. The number of ERCP procedures in 2018 and 2019 decreased by 20.2% and 56.6%, respectively, compared with that in 2020 (P < 0.01); among the 113 emergency ERCPs, the observed numbers in 2018 (n = 42) and 2019 (n = 55) dramatically dropped by 61.9% and 70.9%, respectively, compared with that in 2020 (n = 16). Of the 16 cases in 2020, stone removal was performed in five, biliary stenting in five, sphincterotomy in five, and nasobiliary drainage in one. No case of ERCP-related infection in medical workers or other patients has been reported.
CONCLUSION The COVID-19 outbreak significantly reduced the number of ERCPs; however, there is no difference in the indications and endoscopic interventions before and during the COVID-19 outbreak.

Abstract
BACKGROUND The surge of coronavirus disease 2019 (COVID-19) patients has markedly influenced the treatment policies of tertiary hospitals because of the need to protect medical staff and contain viral transmission, but the impact COVID-19 had on emergency gastrointestinal endoscopies has not been determined.
AIM To compare endoscopic activities and analyze the clinical outcomes of emergency endoscopies performed before and during the COVID-19 outbreak in Daegu, the worst-hit region in South Korea.
METHODS This retrospective cohort study was conducted on patients aged ≥ 18 years that underwent endoscopy from February 18 to March 28, 2020, at a tertiary hospital in Daegu. Demographics, laboratory findings, types and causes of emergency endoscopies, and endoscopic reports were reviewed and compared with those obtained for the same period in 2018 and 2019.
RESULTS From February 18 to March 28, a total of 366 emergent endoscopic procedures were performed: Upper endoscopy (170, 50.6%), endoscopic retrograde cholangiopancreatography (113, 33.6%), and colonoscopy with sigmoidoscopy (53, 15.8%). The numbers of procedures performed in 2018 and 2019 dropped by 48.8% and 54.8%, respectively, compared with those in 2020. During the COVID-19 outbreak, the main indications for endoscopy were melena (36.7%), hematemesis (30.6%), and hematochezia (10.2%). Of the endoscopic abnormalities detected, gastrointestinal bleeding was the most common: 39 cases in 2018, 51 in 2019, and 35 in 2020.
CONCLUSION The impact of COVID-19 is substantial and caused dramatic reductions in endoscopic procedures and changes in patient behaviors. Long-term follow-up studies are required to determine the effects of COVID-19 induced changes in the endoscopy field.

Abstract
Introduction: The management of pancreaticobiliary disorders relies heavily on endoscopic retrograde cholangiopancreatography, which is performed with a duodenoscope. Bacterial colonization of reusable duodenoscopes leading to subsequent infectious outbreaks is well recognized and remains an issue despite efforts to optimize best practices in high-level disinfection. The EXALT Model D duodenoscope (EXALT) (Boston Scientific Corporation, Marlborough, MA) is a single-use device, designed to achieve technical equivalency with reusable devices while eliminating the potential for device-related outbreaks.Areas covered: This review covers the challenges associated with reprocessing duodenoscopes and the development of duodenoscope-related infections, with an emphasis on the use of single-use duodenoscopes as a potential solution to this issue.Expert Opinion: Duodenoscope-related infections are an increasingly recognized problem. Infectious outbreaks harm patients, significantly affect providers and medical centers, and can erode patient trust in the health-care system. Single-use duodenoscopes eliminate both the risk of device-related infection transmission and the need for burdensome duodenoscope reprocessing. In clinical evaluations, the EXALT device has demonstrated an equivalent technical performance and provider satisfaction compared to reusable duodenoscopes. Increasing use of this device will clarify how it compares to reusable duodenoscopes in a variety of clinical settings among endoscopists of varying skills levels.

Abstract
BACKGROUND AND AIMS Multidrug-resistant infectious outbreaks associated with duodenoscopes have been documented internationally. Single-use duodenoscopes, disposable distal ends, or distal end cap sealants could eliminate or reduce exogenous patient-to-patient infection associated with ERCP. METHODS This document reviews technologies that have been developed to help reduce or eliminate exogenous infections because of duodenoscopes. RESULTS Four duodenoscopes with disposable end caps, 1 end sheath, and 2 disposable duodenoscopes are reviewed in this document. The evidence regarding their efficacy in procedural success rates, reduction of duodenoscope bacterial contamination, clinical outcomes associated with these devices, safety, and the financial considerations are discussed. CONCLUSIONS Several technologies discussed in this document are anticipated to eliminate or reduce exogenous infections during endoscopy requiring a duodenoscope. Although disposable duodenoscopes can eliminate exogenous ERCP-related risk of infection, data regarding effectiveness are needed outside of expert centers. Additionally, with more widespread adoption of these new technologies, more data regarding functionality, medical economics, and environmental impact will accrue. Disposable distal end caps facilitate duodenoscope reprocessing; postmarketing surveillance culture studies and real-life patient infection analyses are important areas of future research.

Abstract
The current COVID-19 pandemic is a great challenge for worldwide researchers in the human microbiota area because the mechanisms and long-term effects of the infection at the GI level are not yet deeply understood. In the current review, scientific literature including original research articles, clinical studies, epidemiological reports, and review-type articles concerning human intestinal infection with SARS-CoV-2 and the possible consequences on the microbiota were reviewed. Moreover, the following aspects pertaining to COVID-19 have also been discussed: transmission, resistance in the human body, the impact of nutritional status in relation to the intestinal microbiota, and the impact of comorbid metabolic disorders such as inflammatory bowel disease (IBS), obesity, and type two diabetes (T2D). The articles investigated show that health, age, and nutritional status are associated with specific communities of bacterial species in the gut, which could influence the clinical course of COVID-19 infection. Fecal microbiota alterations were associated with fecal concentrations of SARS-CoV-2 and COVID-19 severity. Patients suffering from metabolic and gastrointestinal (GI) disorders are thought to be at a moderate-to-high risk of infection with SARS-CoV-2, indicating the direct implication of gut dysbiosis in COVID-19 severity. However, additional efforts are required to identify the initial GI symptoms of COVID-19 for possible early intervention.

Abstract
Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), which led to a worldwide pandemic that started in early 2020. Healthcare systems across the world encountered an unprecedented surge of COVID-19 patients resulting in more than half a million deaths globally. COVID-19 has affected multiple sub-specialties and procedure-related fields, including gastroenterology. Gastrointestinal (GI) endoscopy centers are specialized units where thousands of endoscopies are performed annually. A significant proportion of these procedures are affected due to the national and regional lockdowns across the globe. To adapt to this rapidly evolving situation, endoscopy centers have undergone significant changes and have taken unprecedented precautions to avoid the transmission of the virus. However, endoscopy centers are going through financial strain due to a reduction in the number of procedures from lockdowns and fear of virus transmission. Theoretically, endoscopies could add to the disease transmission as SARS-CoV-2 has shown to be present in the GI secretions. Multiple precautions such as mandatory use of face masks, safe distancing, use of barriers between the endoscopists and patients, negative pressure rooms, extended use of personal protective equipment, and volume reduction have been taken to decrease the risk of disease transmission by these centers. Moreover, pre-endoscopy COVID-19 testing has now become the norm. In this review, we highlight the significant changes assumed by the endoscopy center. Furthermore, we discuss cost-related concerns of pre-endoscopy COVID-19 testing, the downtime and delays related to the procedures, and effects of rescheduling. As the pandemic progresses through multiple phases, endoscopy centers should use a dynamic approach to adapt and strive to provide the best patient care.

Abstract
Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. The infection started as an outbreak of pneumonia-like symptoms in Wuhan, China. Within a few weeks, it spread across the entire globe resulting in millions of cases and thousands of deaths. While respiratory symptoms and complications are well-defined and can be severe, non-respiratory symptoms of COVID-19 are increasingly being recognized. Gastrointestinal manifestations such as nausea, vomiting, diarrhea, and abdominal pain have been added to the list of common COVID-19 symptoms. Their prevalence has been increasing, probably due to increased recognition and experience with the pandemic. Furthermore, diarrhea and stool testing may change prevalence and transmission rates due to suspicion for fecal-oral transmission of the COVID-19. Due to this risk, various countries have started testing wastewater and sewage systems to examine its role in the spread of SARS-CoV-2 among communities. In this review article, we describe the common gastrointestinal manifestations in COVID-19, their prevalence based upon the current literature, and highlight the importance of early recognition and prompt attention. We also note the role of fecal-oral transmission. Furthermore, the mechanisms of these symptoms, the role of medications, and potential contributing factors are also elaborated.

Abstract
With reports of ongoing duodenoscope contamination and pathogen transmission despite strict adherence to manufacturer reprocessing instructions, professional societies continue to release updated recommendations. Despite general guideline similarities, there are differences. Although adherence to guidelines does not entirely eliminate pathogen contamination or transmission, it is critical to strictly adhere to updated guidelines for maximum risk reduction. In the United States, the Food and Drug Administration and Centers for Disease Control and Prevention continue to offer updates regarding improved duodenoscope reprocessing techniques and endoscope design. This article critically analyzes currently available national and international duodenoscope reprocessing guidelines.

Abstract
BACKGROUND : A significant proportion of duodenoscope-transmitted infections have resulted from errors related to reprocessing. Remote video auditing (RVA) is a tool that can monitor reprocessing compliance but it has not been previously evaluated in a tertiary care setting. The aims of this study were to evaluate: 1) RVA feasibility in a tertiary care setting (defined as the ability to audit every step of duodenoscope reprocessing without delaying the next procedure due to unavailability of duodenoscopes); and 2) the use of RVA as a compliance monitoring tool. METHODS : This was a prospective study at a tertiary care center. A video camera with offsite monitoring was installed in March 2018. Auditors delivered a compliance score after each procedure. The duodenoscope was not used until it passed the audit. Feasibility and compliance data were collected from April 2018 to August 2019 after a 1-month run-in phase. Both per-step compliance and overall 100 % compliance rates were measured. RESULTS : Of 743 duodenoscope reprocessing procedures, 32 666 individual steps were audited and 99.9 % of the steps were fully viewable. The mean time per audit was 38.3 minutes, the mean duodenoscope turnover time was 76.1 minutes, and there were no delays to the next procedure due to unavailability of duodenoscopes. The per-step compliance rate was 99.5 % but the overall 100 % compliance rate was 90.3 %. CONCLUSIONS : The use of RVA in duodenoscope reprocessing was feasible and promoted sustained high-level compliance in a tertiary care center.

Abstract
BACKGROUND & AIMS Disposable, single-use duodenoscopes might reduce outbreaks of infections associated with endoscope reuse. We tested the feasibility, preliminary safety, and performance of a new single-use duodenoscope in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). METHODS We conducted a case-series study of the outcomes of ERCP with a single-use duodenoscope from April through May 2019 at 6 academic medical centers. We screened consecutive patients (18 years and older) without alterations in pancreaticobiliary anatomy and enrolled 73 patients into the study. Seven expert endoscopists performed roll-in maneuvers (duodenoscope navigation and visualization of duodenal papilla only) in 13 patients and then ERCPs in the 60 other patients. Outcomes analyzed included completion of ERCP for the intended clinical indication, crossover from a single-use duodenoscope to a reusable duodenoscope, endoscopist performance ratings of the device, and serious adverse events (assessed at 72 hours and 7 days). RESULTS Thirteen (100%) roll-in maneuver cases were completed using the single-use duodenoscope. ERCPs were of American Society for Gastrointestinal Endoscopy procedural complexity grade 1 (least complex; 7 patients [11.7%]), grade 2 (26 patients [43.3%]), grade 3 (26 patients [43.3%]), and grade 4 (most complex; 1 patient [1.7%]). Fifty-eight ERCPs (96.7%) were completed using the single-use duodenoscope only and 2 ERCPs (3.3%) were completed using the single-use duodenoscope followed by crossover to a reusable duodenoscope. Median overall satisfaction was 9 out of 10. Three patients developed post-ERCP pancreatitis, 1 patient had post-sphincterotomy bleeding, and 1 patient had worsening of a preexisting infection and required rehospitalization. CONCLUSIONS In a case-series study, we found that expert endoscopists can complete ERCPs of a wide range of complexity using a single-use duodenoscope for nearly all cases. This alternative might decrease ERCP-related risk of infection. Clinicaltrials.gov no: NCT03701958.

Abstract
Carbapenemase-producing Enterobacteriaceae (CPE) have been heavily linked to hospital acquired infections (HAI) thereby leading to futility of antibiotics in treating infections and this have complicated public health problems. There is little knowledge about carbapenemase-producing Klebsiella spp. (CPK) in South Africa. This study aimed at determining the occurrence of CPK in different samples collected from selected environmental niches (hospitals, wastewater treatment plants, rivers, farms) in three district municipalities located in the Eastern Cape Province, South Africa. Molecular identification and characterization of the presumptive isolates were determined using polymerase chain reaction (PCR) and isolates that exhibited phenotypic carbapenem resistance were further screened for the possibility of harbouring antimicrobial resistance genes. One hundred (43%) of the 234 confirmed Klebsiella spp. isolates harboured carbapenem-resistance genes; 10 isolates harboured blaOXA-48-like; 17 harboured blaKPC; and 73 isolates harboured blaNDM-1. The emergence of blaKPC, blaOXA-48-like, and blaNDM-1 carbapenem-resistance genes in Klebsiella species associated with environmental sources is of great concern to public health.

Gastrointest Endosc 2020; 92:199-208.

Abstract
BACKGROUND AND AIMS Duodenoscope contamination is associated with notable patient morbidity and mortality and can occur despite high-level disinfection protocols, requiring a solution that protects against contamination of the endoscope in the first place. METHODS We assessed a newly cleared, single-use device to seal the distal end of duodenoscopes while preserving optics and other endoscope functionality and tested its ability to protect against contamination using dye immersion tests and microbial inoculation. RESULTS Dye immersion tests revealed a complete seal with no leakage. Rigorous microbial challenge tests showed the device can both protect against contamination of the endoscope by external microbes ("outside-in" protection) and shield instruments from contact with pre-existing microbial biofilm on or around the elevator that may have survived reprocessing ("inside-out" protection). Optical and mechanical performance of the endoscope was not compromised by the addition of the device. CONCLUSIONS The results show that this disposable device provides 2-way protection to the duodenoscope from microbial contamination, without the potential for disrupting current equipment, technique, and workflow.

Abstract
A new coronavirus emerged in December 2019 in Wuhan city of China, named as the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), and the disease was called coronavirus disease-2019 (COVID-19). The infection due to this virus spread exponentially throughout China and then spread across >205 nations, including the United States (US). Gastrointestinal (GI) endoscopies are routinely performed in the US and globally. Previous reports of isolated infection outbreaks were reported with endoscopes acting as potential vectors. While multidrug-resistant organisms have been reported to be spread by endoscopes, few cases of viruses such as hepatitis B and C are noted in the literature. COVID-19 is predominately spread by droplet transmission, although recent evidence has showed that shedding in feces and feco-oral transmission could also be possible. It is unclear if COVID-19 could be transmitted by endoscopes, but it could theoretically happen due to contact with mucous membranes and body fluids. GI endoscopies involve close contact with oral and colonic contents exposing endoscopy staff to respiratory and oropharyngeal secretions. This can increase the risk of contamination and contribute to virus transmission. Given these risks, all major GI societies have called for rescheduling elective non-urgent procedures and perform only emergent or urgent procedures based on the clinical need. Furthermore, pre-screening of all individuals prior to endoscopy is recommended. This article focuses on the risk of COVID-19 transmission by GI shedding, the potential role of endoscopes as a vector of this novel virus, including transmission during endoscopies, and prevention strategies including deferral of elective non-urgent endoscopy procedures.

Abstract
Some situations may require endoscopy during the COVID-19 (Coronavirus Disease 2019) pandemic. Here, we describe the necessary precautions in the form of clinical questions and answers (Q&A) regarding the safe deployment of gastrointestinal endoscopy in such situations while protecting endoscopy staff and patients from infection. Non-urgent endoscopy should be postponed. The risk of infection in patients should be evaluated in advance by questionnaire and body temperature. The health of staff must be checked every day. Decisions to employ endoscopy should be based on the institutional conditions and aims of endoscopy. All endoscopic staff need to wear appropriate personal protective equipment (PPE). The endoscope and other devices should be cleaned and disinfected after procedures in accordance with the relevant guidelines. Optimal management of the endoscopy unit is required. Endoscopy for infected patients or those with suspected infection demands exceptional caution. When a patient who undergoes endoscopy is later found to have COVID-19, the members of staff involved are considered exposed to the virus and must not work for at least 14 days if their PPE is considered insufficient. When PPE resources are limited, some equipment may be used continuously throughout a shift as long as it is not contaminated. Details of the aforementioned protective measures are described.

Abstract
On 31 December 2019, the WHO China Country Office was informed of cases of pneumonia of unknown etiology detected in Wuhan (Hubei Province of China). In January 2020, a new coronavirus named SARS-CoV2 was isolated and, since that time, SARS-CoV2 related disease (COVID-19) rapidly spread all over the world becoming pandemic in March 2020. The COVID-19 outbreak dramatically affected the public-health and the health-care facilities organization. Bilio-pancreatic endoscopy is considered a high-risk procedure for cross-contamination and, even though it is not directly involved in COVID-19 diagnosis and management, its reorganization is crucial to guarantee high standards of care minimizing the risk of SARS-CoV2 transmission among patients and health-care providers. Bilio-pancreatic endoscopic procedures often require a short physical distance between the endoscopist and the patient for a long period of time, a frequent exchange of devices, the involvement of a large number of personnel, the use of complex endoscopes difficult to reprocess. On this basis, endoscopic units should take precautions with adjusted management of bilio-pancreatic endoscopy. The aim of this article is to discuss the approach to bilio-pancreatic endoscopy in the COVID-19 era with focus on diagnostic algorithms, indications, management of the endoscopic room, proper use of Personal Protective Equipment and correct reprocessing of instrumentation.

Abstract
Coronavirus-19 (COVID-19) caused by SARS-CoV-2 has become a global pandemic. Risk of transmission may occur during endoscopy and the goal is to prevent infection among healthcare professionals while providing essential services to patients. Asia was the first continent to have a COVID-19 outbreak, and this position statement of the Asian Pacific Society for Digestive Endoscopy shares our successful experience in maintaining safe and high-quality endoscopy practice at a time when resources are limited. Sixteen experts from key societies of digestive endoscopy in Asia were invited to develop position statements, including patient triage and risk assessment before endoscopy, resource prioritisation and allocation, regular monitoring of personal protective equipment, infection control measures, protective device training and implementation of a strategy for stepwise resumption of endoscopy services after control of the COVID-19 outbreak.

Nosocomial outbreak linked to a flexible gastrointestinal endoscope contaminated with an amikacin-resistant ST17 clone of Pseudomonas aeruginosa. Eur J Clin Microbiol Infect Dis 2020; 39:1837-1844.

Abstract
Endoscope contamination is infrequent but can be the source of nosocomial infections and outbreaks. In August 2016, an unexpected increase in the incidence of amikacin-resistant P. aeruginosa isolates (AK-Pae) was observed at a tertiary care center in the south of Spain. An epidemiological and microbiological investigation (August-October 2016) was performed to explain this finding. Isolates from clinical and environmental samples (2 endoscopes used for retrograde cholangiopancreatography; ERCP) were identified by MALDI-TOF. Antimicrobial susceptibility testing was performed using the MicroScan system. Whole-Genome-Sequencing (Miseq, Illumina) was performed to determine the resistome and virulome. Clonal relatedness among isolates was assessed by SpeI-PFGE and MLST. A Caenorhabditis elegans killing assay was performed for virulence testing. Biofilm formation was performed using a colorimetric assay. Four of the 5 patients infected and/or colonized with AK-Pae in August 2016 had undergone ERCP ≤5 days before sample collection. Two endoscopes were contaminated with AK-Pae. Isolates from one endoscope showed an identical PFGE pattern to 9 isolates (cluster I) and differed (1-2 bands) to 5 isolates (cluster II). Isolates from these clusters belonged to the ST17 clone. This S17 clone was characterized by its low virulence in the C. elegans killing assay, and its biofilm-forming ability, slightly superior to that of high-risk clones of P. aeruginosa ST175 and ST235. This outbreak was caused by an endoscope used for ERCP contaminated with an invasive, moderately virulent, biofilm-forming AK-Pae ST17 clone, suggesting the possible emergence of a new high-risk lineage of this clone.

Abstract
BACKGROUND AND AIMS Multidrug-resistant infectious outbreaks associated with duodenoscope reuse have been documented internationally. A single-use endoscope could eliminate exogenous patient-to-patient infection associated with ERCP. METHODS We conducted a comparative bench simulation study of a new single-use and 3 models of reusable duodenoscopes on a synthetic anatomic bench model. Four ERCP tasks were performed: guidewire locking (single-use and 1 reusable duodenoscope only), plastic stent placement and removal, metal stent placement and removal, and basket sweeping. The study schedule included block randomization by 4 duodenoscopes, 4 tasks, and 2 anatomic model ERCP stations. Ability to complete tasks, task completion times, and subjective ratings of overall performance, navigation/pushability, tip control, and image quality on a scale of 1 (worst) to 10 (best) were compared among duodenoscopes. RESULTS All 4 ERCP tasks (total 14 subtasks) were completed by 6 expert endoscopists using all 4 duodenoscopes, with similar task completion times (median, 1.5-8.0 minutes per task) and overall performance ratings by task (median, 8.0-10.0). Navigation/pushability ratings were lower for the single-use duodenoscope than for the 3 reusable duodenoscopes (median, 8.0, 10.0, 9.0, and 9.0, respectively; P < .01). Tip control ratings were similar among all the duodenoscopes (median, 9.0-10.0; P = .77). Image quality ratings were lower for 1 reusable duodenoscope compared with the single-use and other 2 reusable duodenoscopes (median, 8.0, 9.0, 9.0, and 9.0, respectively; P < .01). CONCLUSIONS A new single-use duodenoscope was used to simulate 4 ERCP tasks in an anatomic model, with performance ratings and completion times comparable with 3 models of reusable duodenoscopes.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) is a well-known procedure with both diagnostic and therapeutic utilities in managing pancreaticobiliary conditions. With the advancements of endoscopic techniques, ERCP has become a relatively safe and effective procedure. However, as ERCP is increasingly being utilized for different advanced techniques, newer complications have been noticed. Post-ERCP complications are known, and mostly include pancreatitis, infection, hemorrhage, and perforation. The risks of these complications vary depending on several factors, such as patient selection, endoscopist's skills, and the difficulties involved during the procedure. This review discusses post-ERCP complications and management strategies with new and evolving concepts.

Abstract
Background: The use of a contaminated endoscope may lead to infections due to the transmission of potential pathogens from patient to patient. Methods: Post-reprocessing microbiological surveillance of four duodenoscopes was carried out over a three-year period in the Digestive Endoscopy Unit of an Italian hospital. Sampling of duodenoscopes was performed after the devices have been reprocessed. The initial phase of surveillance involved the contemporary evaluation of the four duodenoscopes; afterwards, microbiological surveillance proceeded at monthly intervals. Results: The initial phase of surveillance revealed that three duodenoscopes presented a high level of contamination with “high-concern” micro-organisms, some of which were multi-drug-resistant. The highest values of contamination regarded the species P. aeruginosa (2500 CFU/duodenoscope), K. pneumoniae (2580 CFU/duodenoscope), and A. baumannii (2600 CFU/duodenoscope). Since the cultures were repeatedly positive on three successive occasions, the contaminated devices were sent to the manufacturer for evaluation. Audits were carried out with the personnel responsible for reprocessing, which was aimed to optimize the procedures used, and subsequently, only one case of non-conformity was found. Conclusions: Our study highlighted both the potential risk of transmitting pathogens through the use of duodenoscopes and the importance of implementing a well-structured system of microbiological surveillance and training programs, in order to reduce the risk of spreading retrograde cholangiopancreatography (ERCP)-associated infections.
