Abstract
INTRODUCTION Disposable duodenoscopes and duodenoscopes with disposable endcaps are being used in clinical practice to reduce or eliminate the risk of transmitting infections. The study aim was to assess perceptions and experiences regarding the use of these duodenoscopes among advanced endoscopy fellows in a nationally representative sample. METHODS A 17-item electronic survey was sent to 74 advanced endoscopy training programs. The survey was completed by 50 participants and their responses were included for analysis. RESULTS Most participants were from academic training programs (82.7%) and identified as being in their 7th year of post graduate training (92%; PGY-7). Participants performed an average of 414 ERCPs. 29% reported difficulty with cannulation using disposable duodenoscopes versus 15.7% with duodenoscopes with disposable endcaps (vs. standard duodenoscope). 96% of trainees perceived disposable duodenoscopes as not cost effective and 92% stated they would not use this device during independent practice. 100% of trainees stated that they would use duodenoscopes with disposable endcaps during independent practice. For their most challenging cases, 90% of trainees preferred using standard reprocessable duodenoscopes while no trainee indicated they would prefer using a disposable duodenoscope in this scenario. 82% of participants stated that disposable duodenoscopes and disposable endcaps should be used exclusively or preferentially for high-risk patients citing cost, functionality, and concerns regarding environmental impact. DISCUSSION Advanced endoscopy fellows perceive disposable duodenoscopes as impacting technical maneuverability. Concerns about functionality, cost effectiveness and environmental impact are barriers to adoption.

Abstract
BACKGROUND AND AIMS Duodenoscopes with single-use end caps were introduced to minimize infection risk, but are unstudied in pediatrics. METHODS We collected clinical data and endoscopists' evaluations of duodenoscopes with single-use end caps versus reusable duodenoscopes over 18 months. RESULTS A total of 106 ERCPs were performed for patients aged 1-18 (mean 14.2) years. Forty-six involved single-use end caps, with 9 requiring crossover to reusable duodenoscopes. ERCPs involving single-use end caps resulted in more instances of mucosal trauma (10 vs 0, p<0.05) and post-ERCP pancreatitis (4 vs 1, p<0.05), and accounted for 8 of 9 ERCPs requiring advanced cannulation techniques. No post-ERCP infections occurred. Reported challenges included single-use end cap stiffness and difficulty with their alignment for cannulation. CONCLUSIONS We report difficulty with advancement, greater reliance on advanced cannulation techniques, and higher rates of PEP when using duodenoscopes with single-use end caps in pediatric ERCP. This area warrants further study.

Abstract
BACKGROUND An inpatient endoscopy unit is a care hub for patients from throughout the hospital and can be the site of health care-associated infections (HAIs). Shared surfaces and other nonmedical devices (keyboards) have been increasingly recognized as sites of pathogen transmission. Beyond standard cleaning of high-touch target areas, we queried whether the addition of automated devices delivering low-intensity doses of ultraviolet (UV)-C radiation could further reduce bioburden in an academic endoscopy unit. METHODS Bioburden on previously identified high-touch/communal surfaces was measured before and after the installation of automated, low-intensity UV-light emitting devices (UV Angel) that passively monitor and disinfect targeted surfaces with Ultraviolet-C light (UV-C) light. RESULTS High-touch sites (keyboards) had a baseline bacterial contamination of >80%, whereas individual procedure rooms and common areas had a >57% contamination rate. Following the implementation of automated UV-C light decontamination, bioburden was reduced on average by >91% at high-touch surfaces and within procedure rooms. DISCUSSION/CONCLUSIONS Nonsterile hubs of patient care could serve as sites of "silent" HAI transmission. We have identified high-touch surfaces within an endoscopy unit that have a high bioburden of bacterial contamination and demonstrated that the installation of passive, automated UV-C light disinfection devices can reduce bioburden significantly, possibly mitigating HAI transmission between patients.

Abstract
BACKGROUND While most adult ERCPs are performed on an outpatient basis, pediatric ERCPs are typically performed on an inpatient basis, or with ERCP followed by at least one night inpatient admission. We have begun performing a substantial proportion of our pediatric ERCPs on an outpatient basis, using our clinical judgment to guide the decision process. In the present study, we compare patient characteristics, indications, and adverse events associated with outpatient vs. inpatient ERCP. METHODS Using our endoscopy database, we identified patients 18 years of age and under who underwent ERCP from 2019 to 2021. Demographics, hospitalization status, indications, findings, interventions, as well as available adverse event and clinical outcomes data were analyzed. RESULTS 147 ERCP procedures were performed during the study period by one of two interventional endoscopists. A subset of 51 (34.7%) patients underwent outpatient ERCP. Comparison of the two groups (outpatient vs. inpatient ERCP) was notable for no statistically significant difference in patient age, range of indications, or proportion of index vs. subsequent ERCP. Overall rates of ERCP-associated adverse events were low and there was no statistically significant difference between adverse events in patients who underwent outpatient vs. inpatient ERCP. CONCLUSION We analyzed outpatient and inpatient pediatric ERCP patient demographics and ERCP characteristics to identify factors that guide decision to determine whether pediatric ERCPs are performed on an outpatient vs. inpatient basis. There was no significant difference in adverse events associated with outpatient vs. inpatient pediatric ERCPs, attesting to the safety of outpatient ERCP for this subset of patients in the studied context. This is an area worthy of future prospective and multi-center study.

Abstract
BACKGROUND Delivering safe anesthetic care to a patient unable to communicate easily and effectively with the anesthesia team presents many unique challenges. Communication may be limited by language, which can be resolved with translation services, or neurological conditions, such as stroke or traumatic brain injury, which are not easily remedied. In such patients, the inability to communicate effectively can lead to anxiety and negatively impact the patient-anesthesiologist relationship, especially when higher cognitive functions are preserved. CASE REPORT We present a case of a patient with locked-in syndrome (LIS), who presented to our endoscopy unit for a routine colonoscopy. The patient could only communicate with eye movements and blinking, thus limiting our ability to assess their pain or other needs in the perioperative period; however, she was otherwise cognitively intact. By utilizing the patient's home healthcare team and quickly adapting their unique communication methods during the perioperative period, we were able to provide an appropriate, safe anesthetic for this patient with LIS. CONCLUSIONS Many patients requiring an anesthetic are unable to effectively communicate due to language issues, hearing loss/mutism, neurological injury/stroke (aphasia), or developmental disabilities. The unique communication needs of this patient with LIS went beyond utilizing a translator and required the healthcare team to quickly learn a new communication method. We also discuss forms of intraoperative monitoring that can be used to differentiate consciousness from the anesthetized state in LIS patients, as well as making recommendations for future care of such patients.

Abstract
BACKGROUND Clips are endoscopic mechanical devices with tensile and closure strength that can approximate tissue and provide hemostasis through a tamponade effect. Clips are ubiquitously used in endoscopic practice, and numerous studies have validated the clinical efficacy of clips, with recent guidelines recommending them as a first-line intervention for recurrent and persistent nonvariceal gastrointestinal bleeding. However, the safety profile for these devices has yet to be delineated, thus, we aim to investigate this feature by examining the adverse events reported to the Food and Drug Administration. METHODS Postmarketing surveillance data from the Food and Drug Administration Manufacturer And User Facility Device Experience database were analyzed from January 2012 to January 2021. The Manufacturer And User Facility Device Experience database is a reporting software and does not independently verify the details of complications. RESULTS Two thousand five hundred forty reports were issued, of which 287 were patient adverse events and 2766 were device problems. Activation, separation, and positioning issues were most common. No consequences or clinically significant impact on patients were seen in 1968 reports. Foreign bodies were seen in 97 cases, hemorrhage in 57 cases, tissue damage in 42 cases, embedded clips in tissues/plaques in 16 cases, perforation in 15 cases, lacerations in 6 cases, and infection in 3 cases. CONCLUSIONS While the most commonly reported device problems involved activation, separation, and positioning, most patients were clinically unaffected. Moreover, perforation and infection were exceedingly rare, further highlighting the safety profile of endoscopic clips.

Abstract
OBJECTIVE There is an unmet clinical need for effective, targeted interventions to prevent post-ERCP pancreatitis (PEP). We previously demonstrated that the serine-threonine phosphatase, calcineurin (Cn) is a critical mediator of PEP and that the FDA-approved calcineurin inhibitors, tacrolimus (Tac) or cyclosporine A, prevented PEP. Our recent observations in preclinical PEP models demonstrating that Cn deletion in both pancreatic and hematopoietic compartments is required for maximal pancreas protection, highlighted the need to target both systemic and pancreas-specific Cn signaling. We hypothesized that rectal administration of Tac would effectively mitigate PEP by ensuring systemic and pancreatic bioavailability of Tac. We have tested the efficacy of rectal Tac in a preclinical PEP model and in cerulein-induced experimental pancreatitis. METHODS C57BL/6 mice underwent ductal cannulation with saline infusion to simulate pressure-induced PEP or were given seven, hourly, cerulein injections to induce pancreatitis. To test the efficacy of rectal Tac in pancreatitis prevention, a rectal Tac suppository (1 mg/kg) was administered 10 min prior to cannulation or first cerulein injection. Histological and biochemical indicators of pancreatitis were evaluated post-treatment. Pharmacokinetic parameters of Tac in the blood after rectal delivery compared to intravenous and intragastric administration was evaluated. RESULTS Rectal Tac was effective in reducing pancreatic injury and inflammation in both PEP and cerulein models. Pharmacokinetic studies revealed that the rectal administration of Tac helped achieve optimal blood levels of Tac over an extended time compared to intravenous or intragastric delivery. CONCLUSION Our results underscore the effectiveness and clinical utility of rectal Tac for PEP prophylaxis.

Abstract
BACKGROUND AND AIMS Pancreaticobiliary diseases are common in the elderly. To this end, frailty represents a state of vulnerability that should be considered when assessing the risks and benefits of therapeutic endoscopic procedures. We aim to determine the rate of readmissions and clinical outcomes using the validated Hospital Frailty Risk Score in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). METHODS Using the National Readmissions Database, we identified patients with an admission diagnosis of cholangitis with obstructive stone from 2016 to 2019. Patients were determined to be of low frailty risk with a score of < 5, while patients of medium to high frailty risk had a score of > 5. RESULTS During the study period, 5751 patients were identified with acute cholangitis with obstructing stone. Mean age of index admissions was 69.4 years and 51.8% were female. From the total cohort, 5119 (89.2%) patients underwent therapeutic ERCP, 38.0% (n = 1947) of whom were regarded as frail (risk score > 5). Following ERCP, frail patients had a less but statistically insignificant readmission rate compared to non-frail patients (2.76% vs 4.05%, p = 0.450). However, compared to non-frail patients, frail patients experienced higher post-ERCP complications (6.20% vs 14.63%, p < 0.001). Frail patients were more likely to have longer lengths of stay, higher hospital cost, and mortality risk. CONCLUSION ERCP is not a risk factor for readmission among frail patients. However, frail patients are at higher risk for procedure-related complications, healthcare utilization, and mortality.

Abstract
BACKGROUND AND AIMS Complex endoscopic procedures are increasingly performed with anesthesia support, which substantially affects endoscopy unit efficiency. ERCP performed with the patient under general anesthesia presents unique challenges, as patients are typically first intubated, then transferred to the fluoroscopy table and positioned semi-prone. This requires additional time and staff while increasing the potential for patient/staff injury. We have developed the technique of endoscopist-facilitated intubation using an endotracheal tube backloaded onto an ultra-slim gastroscope as a potential solution to these issues and evaluated its utility prospectively. METHODS Sequential patients undergoing ERCP were randomized to undergo endoscopist-facilitated intubation or to standard intubation. Demographic data, patient/procedure characteristics, endoscopy efficiency parameters, and adverse events were analyzed. RESULTS During the study period, 45 ERCP patients were randomized to undergo either endoscopist-facilitated intubation (n = 23) or standard intubation (n = 22). Endoscopist-facilitated intubation was successful in all patients, with no hypoxic events. Median time from patient arrival in room to procedural start was shorter in patients undergoing endoscopist-facilitated intubation versus standard intubation (8.2 vs 29 minutes, P < .0001). Endoscopist-facilitated intubations were brisker than standard intubations (.63 vs 2.85 minutes, P < .0001). Patients undergoing endoscopist-facilitated intubation reported less postprocedure throat discomfort (13% vs 50%, P < .01) and fewer myalgia incidences (22% vs 73%, P < .01) than patients undergoing standard intubation. CONCLUSIONS Endoscopist-facilitated intubation was technically successful in every patient. Median endoscopist-facilitated intubation time from patient arrival in room to procedural start was 3.5-fold lower, and median endoscopist-facilitated intubation time was >4-fold lower, than for standard intubation. Endoscopist-facilitated intubation significantly enhanced endoscopy unit efficiency and minimized staff and patient injury. General adoption of this novel approach may represent a paradigm shift in the approach to safe and efficient intubation of all patients requiring general anesthesia. Although the results of this controlled trial are promising, larger studies in a broad population are needed to validate these findings. (Clinical trial registration number: NCT03879720.).

Abstract
Children and adolescents are increasingly impacted by pancreatic disease. Interventional endoscopic procedures, including endoscopic retrograde cholangiopancreatography) and endoscopic ultrasonography, are integral to the diagnosis and management of many pancreatic diseases in the adult population. In the past decade, pediatric interventional endoscopic procedures have become more widely available, with invasive surgical procedures now being replaced by safer and less disruptive endoscopic interventions.

Abstract
OBJECTIVE There is an urgent need for safe and targeted interventions to mitigate post-ERCP pancreatitis (PEP). Calcineurin inhibitors (CnIs) offer therapeutic promise as calcineurin signaling within acinar cells is a key initiating event in PEP. In previous proof-of-concept studies using experimental models, we showed that concurrent intra-pancreatic ductal administration of the CnIs, tacrolimus (Tac) or cyclosporine A (CsA) with the ERCP radiocontrast agent (RC) prevented PEP. To translate this finding clinically, we investigated potential toxic effects of intraductal delivery of a single-dose RC-CnI formulation on endocrine pancreas function and systemic toxicities in a preclinical PEP model. METHODS C57BL/6J mice underwent ductal cannulation and received a single, intra-pancreatic ductal infusion of RC or RC with Tac or CsA (treatment groups) or underwent ductal cannulation without infusion ('sham' group). To assess endocrine function, intraperitoneal glucose tolerance test (IPGTT) was performed at two days before infusion and on day 2 and 14 post-surgery. To evaluate off-target tissue toxicities, renal and hepatic function-related parameters including blood urea nitrogen, plasma creatinine, potassium, aspartate aminotransferase, alanine aminotransferase, and total bilirubin were measured at the same time-points as IPGTT. Histological and biochemical indicators of pancreas injury and inflammation were also evaluated. RESULTS No abnormalities in glucose metabolism, hepatic or renal function were observed on day 2 or 14 in mice administered with intraductal RC or RC with Tac or CsA. CONCLUSION Intraductal delivery of RC-CnI formulation was safe and well-tolerated with no significant acute or subacute endocrine or systemic toxicities, underscoring its clinical utility to prevent PEP.

Abstract
Among drug-induced adverse events, pancreatitis is life-threatening and results in substantial morbidity. A prototype example is the pancreatitis caused by asparaginase, a crucial drug used to treat acute lymphoblastic leukemia (ALL). Here, we used a systems approach to identify the factors affecting asparaginase-associated pancreatitis (AAP). Connectivity Map analysis of the transcriptomic data showed that asparaginase-induced gene signatures were potentially reversed by retinoids (vitamin A and its analogs). Analysis of a large electronic health record database (TriNetX) and the U.S. Federal Drug Administration Adverse Events Reporting System demonstrated a reduction in AAP risk with concomitant exposure to vitamin A. Furthermore, we performed a global metabolomic screening of plasma samples from 24 individuals with ALL who developed pancreatitis (cases) and 26 individuals with ALL who did not develop pancreatitis (controls), before and after a single exposure to asparaginase. Screening from this discovery cohort revealed that plasma carotenoids were lower in the cases than in controls. This finding was validated in a larger external cohort. A 30-day dietary recall showed that the cases received less dietary vitamin A than the controls did. In mice, asparaginase administration alone was sufficient to reduce circulating and hepatic retinol. Based on these data, we propose that circulating retinoids protect against pancreatic inflammation and that asparaginase reduces circulating retinoids. Moreover, we show that AAP is more likely to develop with reduced dietary vitamin A intake. The systems approach taken for AAP provides an impetus to examine the role of dietary vitamin A supplementation in preventing or treating AAP.

Abstract
INTRODUCTION Pancreas Divisum (PD) is a common pancreatic ductal variant which is twice as common in pediatric patients with acute recurrent pancreatitis (ARP) relative to the general population (14% vs. 7%). Endoscopic retrograde cholangiopancreatography (ERCP) with minor papillotomy has been performed to facilitate drainage of pancreatic juice from the diminutive minor papilla to prevent pancreatitis and pancreatic damage. METHODS We searched our prospectively-maintained endoscopy databases for patients 18 and younger who underwent ERCP with minor papillotomy between 2009 and 2019. Demographic data, indications, procedural interventions and findings, as well as available clinical outcomes data were analyzed. RESULTS 54 ARP/PD patients underwent ERCP with minor papillotomy. Median age was 14 (range 7-18) years, and 26 (48.1%) patients were female. Post-ERCP pancreatitis developed in 10/54 patients (18.5%). 12-month post-ERCP clinical trajectory was available in 47/54 (87%) patients and most patients (38/47, 80.8%) improved clinically after minor papillotomy, with 9/47 (19.1%) experiencing resolution of pancreatitis episodes and none indicated worsening severity or frequency of pancreatitis episodes following ERCP. CONCLUSION The majority of children and adolescents with PD and ARP who underwent ERCP with minor papillotomy experienced subjective improvement in their symptoms following the intervention. These data suggest that ERCP with minor papillotomy for pediatric patients with PD and ARP is beneficial and may be curative in a subset of patients-higher rates of improvement than have been previously reported in adults.

Abstract
(1) Background: Abnormal liver function tests are commonly encountered in clinical practice, often leading to additional workup to determine the underlying etiology of these abnormal laboratory studies. As part of this evaluation, if less invasive imaging studies are performed and are without evidence of biliary obstruction, liver biopsy may be performed, and the finding of large duct obstruction on liver biopsy is commonly encountered. The utility of endoscopic retrograde cholangiopancreatography (ERCP) for evaluation and management of possible biliary obstruction in patients with large duct obstruction on liver biopsy has not been studied to date. (2) Methods: To assess the utility of ERCP in patients with large bile duct obstruction on liver biopsy, we retrospectively evaluated patients with large duct obstruction on liver biopsy from 2010-2019 at our tertiary care and transplant center. Demographic and clinical characteristics were evaluated for all patients, with sub-group analysis for patients who underwent ERCP and those who had intervenable findings at the time of ERCP. Descriptive statistics with proportions, means, and standard deviations were performed for demographics and clinical variables using absolute standardized difference. (3) Results: During the study period, 189 liver biopsies with evidence of large duct obstruction were performed. After exclusion criteria were applied, 166 unique patients were eligible for the study. Ninety-one patients with evidence of large duct obstruction on liver biopsy underwent ERCP and 75 did not. Of the 91 patients who underwent ERCP, 76 patients (84%) had an intervenable finding at ERCP. Patients who underwent ERCP were overall more likely to have had a liver transplant (65% ASD 0.63), have previously undergone cholecystectomy (80%, ASD 0.56), and be immunocompromised (80%, ASD 0.56). (4) Conclusions: ERCP is high yield when large duct obstruction is apparent on liver biopsy, with the majority of patients (84%) who undergo ERCP in this clinical context having a biliary finding necessitating therapeutic endoscopic intervention.

Abstract
BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) is increasingly utilized for management of biliary disorders in children and adolescents. Practice patterns surrounding cholangioscopy in pediatric patients, however, are largely uncharacterized. METHODS We retrospectively analyzed all ERCPs in which cholangioscopy was performed on patients 18 and under at our tertiary care children's hospital from 2015 to 2020 using our institution's paper and electronic medical record system. Patient demographics, procedure indications, interventions, and associated adverse events were analyzed. RESULTS Over the study period, 307 ERCPs were performed on 282 patients at our children's hospital. Cholangioscopy was performed in 36 procedures (11.7%) using the SpyGlass cholangioscope (Boston Scientific). Antibiotics to cover biliary organisms were administered to all patients precholangioscopy. Mean patient age was 13.6 years (range 7-18 years). The 2 most common indications for cholangioscopy included electrohydraulic lithotripsy for biliary stone disease and evaluation of biliary stricture (with incidental finding of biliary web in 2 patients and retained suture material in 2 patients). Adverse events were less prevalent in patients who underwent cholangioscopy relative to those who underwent ERCP. 0/36 (0%) developed post-ERCP pancreatitis, one patient had self-limited melena (possible self-limited postsphincterotomy bleeding). Patient care was enhanced by cholangioscopy in 30/36 (83.3%) of these patients. CONCLUSIONS These data attest to the safety and clinical utility of cholangioscopy in children and adolescents. Cholangioscopy was performed in just over 11% of pediatric patients who underwent ERCP at our academic medical center-rates similar to those reported in adult patients. The radiation-sparing nature of cholangioscopy, coupled with these data supporting its safety, make it particularly appealing for use in children. Further multi-institution evaluation of the utility, safety, and range of indications for cholangioscopy in other practice settings would be of great interest and help guide endoscopic care.

Abstract
10021 Background: Asparaginase is a key component of treatment of acute lymphoblastic leukemia (ALL), which is the most common cancer in the pediatric population. However, asparaginase is associated with many toxicities, including pancreatitis, which is observed in up to 10% of patients and can lead to severe sequelae. Methods: We performed analysis of (1) transcriptomic data from (a) asparaginase-treated leukemic cells, and (b) the pancreas of mice that were induced with a chemical form of pancreatitis; (2) the US FDA Adverse Reporting System (FAERS) and electronic health records (TriNetX); (3) global plasma metabolomic screen and dietary intake evaluation from ALL patients; and (4) experimental animal studies to identify factors that impact asparaginase-associated pancreatitis (AAP). Results: Connectivity map analysis showed that asparaginase-induced gene signatures are potentially reversed by the retinoids (vitamin A and its natural and synthetic analogs). Analysis of TriNetX and FAERES demonstrated a 2-fold reduction in AAP risk with concomitant exposure to vitamin A. Further, we performed a case-control metabolomic study of 50 subjects with ALL enrolled in the Dana-Farber Cancer Institute DFCI ALL clinical trial protocols 05-001 (NCT00400946) and 11-001 (NCT01574274). All subjects were given a single dose of pegylated E. Coli asparaginase during induction therapy. Twenty-four subjects developed pancreatitis within 9 months from the start of induction therapy and were considered cases. The median time to develop pancreatitis among cases was 3.68 months (interquartile range: 3.58 months). Twenty-six control subjects were identified among patients who did not develop pancreatitis within the same evaluation period. The controls were matched for age, sex, and initial ALL risk. The screening revealed that the plasma levels of carotene diol isomers, from the start of induction to its end, were reduced by about 60% in the cases compared to the controls. A detailed 30-day dietary recall showed that the cases had received less dietary vitamin A than the controls during induction therapy. Notably, the median value for the composite intake of vitamin A constituents, termed the RAE (retinol activity equivalents) was 656.92 mcg per day among the controls, but was 34.6% lower among in the cases (median of 429.40 mcg per day, which is just above the recommended dietary allowance level of 400 mcg per day for the 4–8 year-old age group). In mice, asparaginase administration as a single agent was sufficient to reduce circulating and hepatic retinol levels. Conclusions: Based on these data, we propose that circulating retinoids maintain pancreatic health, that asparaginase reduces circulating retinoids, and AAP is more likely to develop with reduced dietary vitamin A intake. The systems approach provides the impetus to examine the role of dietary vitamin A supplementation for preventing or treating AAP.

Abstract
BACKGROUND AND AIMS Transmission of multidrug-resistant organisms by duodenoscopes during ERCP is problematical. The U.S. Food and Drug Administration recently recommended transitioning away from reusable fixed-endcap duodenoscopes to those with innovative device designs that make reprocessing easier, more effective, or unnecessary. Partially disposable (PD) duodenoscopes with disposable endcaps and fully disposable (FD) duodenoscopes are now available. We assessed the relative cost of approaches to minimizing infection transmission, taking into account duodenoscope-transmitted infection cost. METHODS We developed a Monte Carlo analysis model in R (R Foundation for Statistical Computing, Vienna, Austria) with a multistate trial framework to assess the cost utility of various approaches: single high-level disinfection (HLD), double HLD, ethylene oxide (EtO) sterilization, culture and hold, PD duodenoscopes, and FD duodenoscopes. We simulated quality-adjusted life years (QALYs) lost by duodenoscope-transmitted infection and factored this into the average cost for each approach. RESULTS At infection transmission rates <1%, PD duodenoscopes were most favorable from a cost utility standpoint in our base model. The FD duodenoscope minimizes the potential for infection transmission and is more favorable from a cost utility standpoint than use of reprocessable duodenoscopes after single or double HLD at all infection rates, EtO sterilization for infection rates >.32%, and culture and hold for infection rates >.56%. Accounting for alternate scenarios of variation in hospital volume, QALY value, post-ERCP lifespan, and environmental cost shifted cost utility profiles. CONCLUSIONS Our model indicates that PD duodenoscopes represent the most favorable option from a cost utility standpoint for ERCP, with anticipated very low infection transmission rates and a low-cost disposable element. These data underscore the importance of cost calculations that account for the potential for infection transmission and associated patient morbidity/mortality.

Abstract
Endoscopic mucosal resection (EMR) is an endoscopic technique used to remove sessile or flat lesions from the gastrointestinal tract. This article reviews EMR and focuses on large colorectal polyps, which constitute the most common indication for EMR. Various methods of polyp evaluation can help gastroenterologists determine whether EMR is feasible and whether referral to an advanced endoscopist may be necessary. Techniques for performing EMR include conventional hot-snare EMR with submucosal injection and electro-cautery snare removal of colorectal lesions, as well as alternative EMR techniques such as cold-snare EMR and underwater EMR. Key adverse events associated with EMR include bleeding, perforation, and post-polypectomy coagulation syndrome. Finally, as residual or recurrent polyp formation is possible regardless of EMR technique, this article addresses the importance of surveillance post-EMR and the patients who are at highest risk for polyp recurrence.

Abstract
BACKGROUND AND AIMS Direct endoscopic necrosectomy (DEN) of walled-off pancreatic necrosis (WOPN) lacks dedicated instruments and requires repetitive and cumbersome procedures. This study evaluated the safety and efficacy of a new powered endoscopic debridement (PED) system designed to simultaneously resect and remove solid debris within WOPN. METHODS This was a single-arm, prospective, multicenter, international device trial conducted from November 2018 to August 2019 at 10 sites. Patients with WOPN ≥6 cm and ≤22 cm and with >30% solid debris were enrolled. The primary endpoint was safety through 21 days after the last DEN procedure. Efficacy outcomes included clearance of necrosis, procedural time, adequacy of debridement, number of procedures until resolution, hospital stay duration, and quality of life. RESULTS Thirty patients (mean age, 55 years; 60% men) underwent DEN with no device-related adverse events. Of 30 patients, 15 (50%) achieved complete debridement in 1 session and 20 (67%) achieved complete debridement within 2 or fewer sessions. A median of 1.5 interventions (range, 1-7) were required. Median hospital stay was 10 days (interquartile range, 22). There was an overall reduction of 91% in percent necrosis within WOPN from baseline to follow-up and 85% in collection volume. Baseline WOPN volume was positively correlated with the total number of interventions (ρ = .363, P = .049). CONCLUSIONS The new PED system seems to be a safe and effective treatment tool for WOPN, resulting in fewer interventions and lower hospital duration when compared with published data on using conventional instruments. Randomized controlled trials comparing the PED system with conventional DEN are needed. (Clinical trial registration number: NCT03694210.).

Abstract
Background and study aims Outbreaks of endoscopy-related infections have prompted evaluation for potential contributing factors. We and others have demonstrated the utility of borescope inspection of endoscope working channels to identify occult damage that may impact the adequacy of endoscope reprocessing. The time investment and training necessary for borescope inspection have been cited as barriers preventing implementation. We investigated the utility of artificial intelligence (AI) for streamlining and enhancing the value of borescope inspection of endoscope working channels. Methods We applied a deep learning AI approach to borescope inspection videos of the working channels of 20 endoscopes in use at our academic institution. We evaluated the sensitivity, accuracy, and reliability of this software for detection of endoscope working channel findings. Results Overall sensitivity for AI-based detection of borescope inspection findings identified by gold standard endoscopist inspection was 91.4 %. Labels were accurate for 67 % of these working channel findings and accuracy varied by endoscope segment. Read-to-read variability was noted to be minimal, with test-retest correlation value of 0.986. Endoscope type did not predict accuracy of the AI system ( P = 0.26). Conclusions Harnessing the power of AI for detection of endoscope working channel damage and residue could enable sterile processing department technicians to feasibly assess endoscopes for working channel damage and perform endoscope reprocessing surveillance. Endoscopes that accumulate an unacceptable level of damage may be flagged for further manual evaluation and consideration for manufacturer evaluation/repair.

Abstract
The use of ultraviolet germicidal irradiation (UVGI) to combat disease transmission has come into the international spotlight again because of the recent SARS-CoV-2 pandemic and ongoing outbreaks of multidrug resistant organisms in hospitals. Although the implementation of ultraviolet disinfection technology is widely employed in healthcare facilities and its effectiveness has been repeatedly demonstrated, the use of such technology in the commercial sector has been limited. Considering that most disease transmission occurs in commercial, public, and residential indoor environments as opposed to healthcare facilities, there is a need to understand whether ultraviolet (UV) disinfection technology can be effective for mitigating disease transmission in these environments. The results presented here demonstrate that the installation of fixed in-room UVGI air cleaners in commercial buildings, including restaurants and offices, can produce significant reductions in both airborne and surface-borne bacterial contamination. Total airborne reductions after UV implementation at six separate commercial sites averaged 73% (p < 0.0001) with a range of 71-88%. Total non-high touch surface reductions after implementation averaged 55% (p < 0.0001) with a range of 28-88%. All reductions at the mitigated sites were statistically significant. The mean value of indoor airborne bacteria was 320 CFU/m3 before intervention and 76 CFU/m3 after. The mean value of indoor non-high touch surface borne bacteria was 131 CFU/plate before intervention and 47 CFU/plate after. All test locations and controls had their required pandemic cleaning procedures in place for pre- and post-sampling events. Outdoor levels of airborne bacteria were monitored and there was no significant correlation between the levels of airborne bacteria in the outside air as opposed to the indoor air. Rooms with fixed in-room UVGI air cleaners installed had significant CFU reductions on local surface contamination, which is a novel and important finding. Installation of fixed in-room UVGI air cleaners in commercial buildings will decontaminate the indoor environment and reduce hazardous exposure to human pathogens.

Abstract
BACKGROUND AND AIMS There are few data on the quality of EUS in the community setting. We characterized EUS performance at the individual facility level in 3 large American states, using need for repeat biopsy (NRB) as a metric for procedural failure, and the rate of unplanned hospital encounters (UHEs) as a metric for adverse events. METHODS We collected data on 76,614 EUS procedures performed at 166 facilities in California, Florida, and New York (2009-2014). The endpoints for the study were 7-day rate of UHEs after EUS, and 30-day rate of NRB after EUS with fine-needle aspiration. Facility-level factors analyzed included annual procedure volume, urban/rural location, and free-standing status (facilities not attached to a larger hospital). Predictors for UHE and NRB were analyzed in both multivariable regression and nonparametric local regression. RESULTS Facility volume did not predict risk for UHEs. However, high facility volume protected against NRB (P trend <.001) even after adjustment for other facility-level factors. When regressing facility volume against risk for NRB in local regression, a join point (inflection point) was identified at 97 procedures per annum. Once facilities reached this threshold volume, there appeared little additional protective effect of higher volume. Rural facility location (odds ratio, 1.81; 95% confidence interval, 1.36-2.40) and free-standing status (odds ratio, 1.57; 95% confidence interval, 1.16-2.13) were also associated with NRB. CONCLUSION Facility volume does not predict risk for adverse events after EUS. However, high facility volume is associated with decreased rates of technical failure (as assessed by NRB). These data provide one of the first descriptions of EUS practice in community settings and highlight opportunities to improve endoscopic quality nationally.

Abstract
Acute pancreatitis (AP) is associated with significant morbidity and mortality, and it substantially contributes to the healthcare burden of gastrointestinal disease and quality of life in children and adults. AP across the lifespan is characterized by similarities and differences in epidemiology, diagnostic modality, etiologies, management, adverse events, long-term outcomes, and areas in greatest need of research. In this review, we touch on each of these shared and distinctive features of AP in children and adults, with an emphasis on recent advances in the conceptualization and management of AP.

Abstract
OBJECTIVES To analyze outcome and utilization trends over time of pediatric endoscopic retrograde cholangiopancreatography (ERCP) in an all-capture US population-level study. STUDY DESIGN Using the National Inpatient Sample (2005-2014) and National Readmission Database (2010-2014), we identified pediatric (age <20 years) hospitalizations during which ERCP was performed and assessed ERCP-associated readmissions. International Classification of Diseases, Ninth Revision, Clinical Modification codes were used to identify hospitalization diagnoses, comorbidities, and patient/hospital characteristics. Multivariate logistic regression analyses were performed to determine significant predictors (P < .05) of 30-day readmission. RESULTS A total of 11 060 hospitalized pediatric patients underwent ERCP between 2005 and 2014. Most were female (n = 8859; 81%), aged 14-20 years (n = 9342; 84%), and white (n = 4230; 45%). Most (85%) of ERCPs were therapeutic, and leading indications were biliary (n = 5350; 48%) and pancreatitis (n = 3218; 29%). Thirteen pecent of patients were readmitted post-ERCP. Odds for 30-day readmission were highest for patients with a history of liver transplantation, age 0-4 years, male sex, and obesity (P < .001 for each). Patients in both urban teaching and urban hospitals had much lower odds than those in rural hospitals for prolonged length of stay associated with ERCP. CONCLUSIONS These data represent a comprehensive study of nationwide trends in age-specific volumes and outcomes following ERCP in the pediatric population and provide important insights into trends in pediatric pancreaticobiliary disease management, as well as practice setting, patient characteristics, and patient comorbidities associated with pediatric post-ERCP outcomes, including readmission and length of stay.

Abstract
BACKGROUND ERCP is often performed under monitored anesthesia care (MAC) rather than general anesthesia (GA), with patients positioned semi-prone on the fluoroscopy table. Rarely, a MAC ERCP must be converted to GA due to hypoxia or retained food in the stomach. In these circumstances, standard intubation is associated with a significant delay and potential for patient/staff injury during repositioning. We report a novel endoscopist-driven approach to intubation during ERCP using an ultra-slim, flexible gastroscope with an endotracheal tube backloaded onto it. MATERIALS AND METHODS We identified patients who underwent ERCP from 2014 to 2019, and MAC to GA conversion events. Mode of intubation (standard vs. endoscopist-facilitated) and patient/procedure characteristics were evaluated. All endoscopist-facilitated intubations were performed under anesthesiologist supervision. RESULTS A total of 3409 patients underwent ERCP; 1568 (46%) GA and 1841 (54%) MAC. Of these, 42 (2.3%) required intubation during ERCP and 16 underwent endoscopist-facilitated intubation due to retained food in the stomach and/or hypoxia. In 3 patients, aspirated material was suctioned from the trachea and bronchi using the ultra-slim gastroscope. Immediate post-procedure extubation was successful in all endoscopist-facilitated intubation patients and none exhibited radiographic evidence of aspiration pneumonia. CONCLUSIONS Endoscopist-facilitated intubation using an ultra-slim flexible gastroscope is feasible and expeditious for MAC to GA conversion during ERCP. This technique is readily accomplished in the semi-prone position, while standard intubation requires patient transfer from fluoroscopy table to gurney, with associated delay/risks. These data suggest that further study of this approach is warranted, and this may be the most favorable approach for intubation during ERCP.

Abstract
BACKGROUND AND AIMS ERCP is a high-risk endoscopic procedure, yet reports of ERCP-related adverse events are largely limited to early adverse events based on immediate postprocedure assessment. We hypothesize that immediate/1-day follow-up underestimates the true adverse event rate, and later follow-up calls may enable a more accurate assessment of adverse events, leading to enhanced postprocedural patient care. METHODS Consecutive patients undergoing ERCP at our tertiary care academic medical center from 2018 to 2019 were analyzed. Patients were encouraged to contact us with postprocedure symptoms, and they received phone calls at 1, 7, 14, and 30 days after the procedure using a standardized script to assess for delayed adverse events and unplanned health care encounters. RESULTS This study is notable for a high rate of successful patient follow-up at day 1 (94%) and day 7 (93%). The overall adverse event rate was 1.9% immediately postprocedure, 3.3% on day 1, and 9.8% on day 7. Increased detection of adverse events was accomplished by the day 7 call relative to the day 1 call (pancreatitis 2% vs 0.5%; bleeding 0.5% vs 0.2%; infection 0.9% vs 0.5%). Follow-up calls at 14 and 30 days were lower yield for detection of post-ERCP adverse events. CONCLUSIONS Initial postprocedure assessment and day 1 follow-up calls underestimate adverse event rates/unplanned health care encounters related to ERCP, due to delayed evolution of some adverse events. The day 7 call is optimal in that it resulted in a >3-fold higher rate of detection of adverse events and successful direction of over 10% of symptomatic patients to appropriate assessment and follow-up health care.

Abstract
BACKGROUND Biliary cannulation is readily achieved in > 85% of patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). When standard cannulation techniques fail, salvage techniques utilized include the needle knife precut, double wire technique, and Goff septotomy. METHODS Records of patients undergoing ERCP from 2005 to 2016 were retrospectively examined using a prospectively maintained endoscopy database. Patients requiring salvage techniques for biliary access were analyzed together with a control sample of 20 randomly selected index ERCPs per study year. Demographic and clinical variables including indications for ERCP, cannulation rates, and adverse events were collected. RESULTS A total of 7984 patients underwent ERCP from 2005 to 2016. Biliary cannulation was successful in 94.9% of control index ERCPs, 87.2% of patients who underwent Goff septotomy (significantly higher than for all other salvage techniques, p ≤ 0.001), 74.5% of patients in the double wire group and 69.6% of patients in the needle knife precut group. Adverse event rates were similar in the Goff septotomy (4.1%) and index ERCP control sample (2.7%) groups. Adverse events were significantly higher in the needle knife group (27.2%) compared with all other groups. CONCLUSIONS This study represents the largest study to date of Goff septotomy as a salvage biliary access technique. It confirms the efficacy of Goff septotomy and indicates a safety profile similar to standard cannulation techniques and superior to the widely employed needle knife precut sphincterotomy. Our safety and efficacy data suggest that Goff septotomy should be considered as the primary salvage approach for failed cannulation, with needle knife sphincterotomy restricted to Goff septotomy failures.

Abstract
BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) is a fluoroscopy and endoscopy-based procedure important for diagnosis and management of pediatric pancreaticobiliary disorders. Patient, procedure, endoscopist, and facility characteristics have been shown to influence ERCP complexity and procedure outcomes as well as fluoroscopy utilization in adults; however, the extent to which this is true in pediatric patients remains under-studied and there are minimal data regarding fluoroscopy utilization in pediatric ERCP. METHODS We retrospectively analyzed ERCPs performed on patients <18 years of age at our tertiary care children's hospital from 2002 to 2017 using our institution's paper and electronic medical record system along with a prospectively maintained radiation exposure database. Procedure complexity was graded using the Stanford Fluoroscopy Complexity Score and the American Society of Gastrointestinal Endoscopy Complexity scale. High-volume endoscopists (HVE) were defined as having a cumulative annual ERCP volume >100 and low-volume endoscopists (LVE) as <100 (pediatric + adult) ERCPs/year. RESULTS Three hundred eighty-five ERCPs performed on 321 patients were included in this analysis. The mean patient age was 13.4 years (+/- 4.2 years), 77% were index ERCPs (native ampullas), and 81% were performed with therapeutic intent (87% for biliary indication and 13% for pancreatic indication). Fluoroscopy times (FTs) varied between procedures and providers. Median FT was 4.85 (+/- 2.68) minutes. Endoscopist annual ERCP volume was the strongest predictor of FT (P < 0.001). In addition to endoscopist volume, procedure-specific predictors of increased FT included pancreatic indication for the procedure, biliary or pancreatic duct stricture, patient age <4 years or >16 years at the time of ERCP (P < 0.01 for each), and native ampulla. ERCP complexity rating based on the Stanford Fluoroscopy Complexity Score correlated with FT. CONCLUSIONS Radiation exposure is higher than desirable for pediatric ERCP and varies with endoscopist as well as patient and procedure-specific factors. HVE perform ERCP with lower FT relative to LVE even though HVE procedure complexity was higher. The Stanford Fluoroscopy Score predicted FT for pediatric ERCP, but the ASGE ERCP complexity scale did not. Adaptation and refinement of pediatric-specific ERCP complexity scales including factors, such as patient size and age and indications/interventions more consistent with those encountered in pediatrics could be beneficial.

Abstract
BACKGROUND Biliary dilation is frequently related to obstruction; however, non-obstructive factors such as age and previous cholecystectomy have also been reported. In the past two decades there has been a dramatic increase in opiate use/dependence and utilization of cross-sectional abdominal imaging, with increased detection of biliary dilation, particularly in patients who use opiates.
AIM To evaluate associations between opiate use, age, cholecystectomy status, ethnicity, gender, and body mass index utilizing our institution’s integrated informatics platform.
METHODS One thousand six hundred and eighty-five patients (20% sample) presenting to our Emergency Department for all causes over a 5-year period (2011-2016) who had undergone cross-sectional abdominal imaging and had normal total bilirubin were included and analyzed.
RESULTS Common bile duct (CBD) diameter was significantly higher in opiate users compared to non-opiate users (8.67 mm vs 7.24 mm, P < 0.001) and in patients with a history of cholecystectomy compared to those with an intact gallbladder (8.98 vs 6.72, P < 0.001). For patients with an intact gallbladder who did not use opiates (n = 432), increasing age did not predict CBD diameter (r2 = 0.159, P = 0.873). Height weakly predicted CBD diameter (r2 = 0.561, P = 0.018), but weight, body mass index, ethnicity and gender did not.
CONCLUSION Opiate use and a history of cholecystectomy are associated with CBD dilation in the absence of an obstructive process. Age alone is not associated with increased CBD diameter. These findings suggest that factors such as opiate use and history of cholecystectomy may underlie the previously-reported association of advancing age with increased CBD diameter. Further prospective study is warranted.

Abstract
BACKGROUND At our academic tertiary care medical center, we have noted patients referred for endoscopic retrograde cholangiopancreatography (ERCP) who increasingly require advanced cannulation techniques. This trend is noted despite increased endoscopist experience and annual ERCP volume over the same period.
AIM To evaluate this phenomenon of perceived escalation in complexity of cannulation at ERCP and assessed potential underlying factors.
METHODS Demographic/clinical variables and records of ERCP patients at the beginning (2008), middle (2013) and end (2018) of the last decade were reviewed retrospectively. Cannulation approaches were classified as “standard” or “advanced” and duodenoscope position was labeled as “standard” (short position) or “non-standard” (e.g., long, semi-long).
RESULTS Patients undergoing ERCP were older in 2018 compared to 2008 (69.7 ± 15.2 years vs 55.1 ± 14.7, P < 0.05). Increased ampullary distortion and peri-ampullary diverticula were noted in 2018 (P < 0.001). ERCPs were increasingly performed with a non-standard duodenoscope position, from 2.2% (2008) to 5.6% (2013) and 16.1% (2018) (P < 0.001). Utilization of more than one advanced cannulation technique for a given ERCP increased from 0.7% (2008) to 0.9% (2013) to 6.6% (2018) (P < 0.001). Primary mass size > 4 cm, pancreatic uncinate mass, and bilirubin > 10 mg/dL predicted use of advanced cannulation techniques (P < 0.03 for each).
CONCLUSION Complexity of cannulation at ERCP has sharply increased over the past 5 years, with an increased proportion of elderly patients and those with malignancy requiring advanced cannulation approaches. These data suggest that complexity of cannulation at ERCP may be predicted based on patient/ampulla characteristics. This may inform selection of experienced, high-volume endoscopists to perform these complex procedures.

Abstract
After outbreaks of duodenoscope-transmitted infection with multidrug-resistant organisms, it has become clear that institutions must optimize their endoscope reprocessing programs. Standard endoscope reprocessing practices may not represent the ideal approach for preventing transmission of infection related to endoscopy. We discuss multiple approaches to enhance and optimize reprocessing, drying, and storage of standard duodenoscopes. The optimal enhanced duodenoscope reprocessing modality remains to be determined. Acknowledging the challenges and limitations in effectively reprocessing duodenoscopes, the FDA issued a safety communiqué recommending transitioning to either single use disposable duodenoscopes or duodenoscopes with innovative designs that allow more effective reprocessing.

Abstract
BACKGROUND & AIMS Calcineurin is a ubiquitously expressed central Ca2+-responsive signaling molecule that mediates acute pancreatitis, but little is known about its effects. We compared the effects of calcineurin expression by hematopoietic cells vs pancreas in mouse models of pancreatitis and pancreatitis-associated lung inflammation. METHODS We performed studies with mice with hematopoietic-specific or pancreas-specific deletion of protein phosphatase 3, regulatory subunit B, alpha isoform (PPP3R1, also called CNB1), in mice with deletion of CNB1 (Cnb1UBC△/△) and in the corresponding controls for each deletion of CNB1. Acute pancreatitis was induced in mice by administration of caerulein or high-pressure infusion of radiocontrast into biliopancreatic ducts; some mice were also given intraductal infusions of an adeno-associated virus vector that expressed nuclear factor of activated T -cells (NFAT)-luciferase into pancreas. Pancreas, bone marrow, liver, kidney, heart, and lung were collected and analyzed by histopathology, immunohistochemistry, and immunoblots; levels of cytokines were measured in serum. Mouse and human primary pancreatic acinar cells were transfected with a vector that expressed NFAT-luciferase and incubated with an agent that blocks interaction of NFAT with calcineurin; cells were analyzed by immunofluorescence. Calcineurin-mediated neutrophil chemotaxis and reactive oxygen species production were measured in neutrophils from mice. RESULTS Mice with hematopoietic-specific deletion of CNB1 developed the same level of local pancreatic inflammation as control mice after administration of caerulein or infusion of radiocontrast into biliopancreatic ducts. Cnb1UBC△/△ mice or mice with pancreas-specific deletion of CNB1 developed less severe pancreatitis and reduced pancreatic inflammation after administration of caerulein or infusion of radiocontrast into biliopancreatic ducts compared with control mice. NFAT was activated in pancreas of Swiss Webster mice given caerulein or infusions of radiocontrast into biliopancreatic ducts. Blocking the interaction between calcineurin and NFAT did not reduce pancreatic acinar cell necrosis in response to caerulein or infusions of radiocontrast. Mice with hematopoietic-specific deletion of CNB1 (but not mice with pancreas-specific deletion of CNB1) had reduced infiltration of lung tissues by neutrophils. Neutrophil chemotaxis and production of reactive oxygen species were decreased after incubation with a calcineurin inhibitor. CONCLUSIONS Hematopoietic and neutrophil expression of calcineurin promotes pancreatitis-associated lung inflammation, whereas pancreatic calcineurin promotes local pancreatic inflammation. The findings indicate that the protective effects of blocking or deleting calcineurin on pancreatitis are mediated by the source of its expression. This information should be used in the development of strategies to inhibit calcineurin for the prevention of pancreatitis and pancreatitis-associated lung inflammation.

Abstract
BACKGROUND Rates of incomplete colonoscopy in non-expert settings range up to 13%. Expert colonoscopists can complete ~ 95% colonoscopies when other endoscopists fail; however, a small number remain incomplete even in expert hands, typically due to bowel fixity. AIMS Pentax Retroview™ (EC-3490TLi) is a new slim colonoscope with a short turning radius (STR) and greater tip deflection (210°), which allows easy maneuverability across sharply angulated/fixed colonic bends. We evaluated the utility of this colonoscope for completing colonoscopies that fail even in the hands of expert colonoscopists. METHODS Retrospective chart review was performed, and main outcomes measured included cecal intubation rate, lesions detected, dosage of sedation used, and complications. RESULTS Using the STR colonoscope, complete colonoscopy to the cecum was possible in 34/37 patients (91.9%). No loss of lumen/blind advancement was necessary in any of the procedures. No adverse events occurred. Among the completed colonoscopies, 6/34 (17.6%) patients had adenomas, all proximal to the site of prior failure, including one advanced adenoma. All failures (n = 3, 8.1%) had a history of cancer surgeries, with peritoneal carcinomatosis/extensively fixed/frozen bowel (two patients) and an additional diverticular stricture with colo-vesical fistula (one patient). CONCLUSION STR colonoscope facilitates completion of a high proportion (91.9%) of colonoscopies that previously failed in expert hands. Its STR allows easy maneuverability across segments of sharp angulation with bowel fixity without need for blind advancement. The use of this colonoscope led to the detection of adenomas in 17.6% of patients, all proximal to the site of prior failed colonoscopy.

Abstract
BACKGROUND Fluoroscopy use during ERCP exposes patients and providers to deleterious effects of radiation. Formal training in fluoroscopy/radiation protection is not widely emphasized during therapeutic endoscopy training, and radiation use during GI endoscopy has not previously been characterized in the USA. In this study, we evaluated radiation training, fluoroscopy use patterns, and radiation protection practices among US therapeutic endoscopists. METHODS An anonymous electronic survey was distributed to US therapeutic endoscopists, and responses were analyzed using descriptive statistics. State-specific requirements for fluoroscopy utilization were determined from state radiologic health branches. RESULTS A total of 159 endoscopists (response rate 67.8%) predominantly those working in university hospitals (69.2%) with > 5 years of experience performing ERCP (74.9%) completed the questionnaire. Although the majority of endoscopists (61.6%) reported that they personally controlled fluoroscopy during ERCP, most (56.6%) had not received training on operating their fluoroscopy system. Only a minority (18-31%) of all respondents reported consistently utilizing modifiable fluoroscopy system parameters that minimize patient radiation exposure (pulsed fluoroscopy, frame rate modification or collimation). Endoscopists appear to undertake adequate personal radiation protective measures although use of a dosimeter was not consistent in half of respondents. The majority of states (56.8%) do not have any stated requirement for certification of non-radiologist physicians who intend to operate fluoroscopy. CONCLUSIONS Most US gastroenterologists performing ERCP have not received formal training in operating their fluoroscopy system or in minimizing radiation exposure to themselves and to their patients. Such formal training should be included in all therapeutic endoscopy training programs, and fluoroscopy system-specific training should be offered at all hospitals.

Abstract
BACKGROUND AND AIMS Residual fluid within endoscope working channels after reprocessing may promote growth of pathogens. Current reprocessing guidelines therefore recommend endoscope drying with administration of forced filtered air; however, the duration and modality of administered air are not specified. The new DriScope Aid device enables automated administration of filtered air at controlled pressure through all internal endoscope channels. We systematically compared, for the first time, the impact of manual drying and automated drying on retained working channel fluid and bioburden after reprocessing. METHODS We assessed for residual working channel fluid after reprocessing and/or drying by using the SteriCam borescope. Drying was performed either manually (forced filtered air) or was automated (DriScope Aid) for either 5 or 10 minutes. Adenosine triphosphate (ATP) bioluminescence testing was performed on working channel rinsates after drying, to evaluate for residual bioburden. RESULTS Significantly more fluid droplets were evident after manual drying (4.55 ± 6.14) than with automated device-facilitated drying for either 5 minutes (0.83 ± 1.29; P = .007) or 10 minutes (0 ± 0; P = .001). ATP bioluminescence values were higher for manual drying compared with automated drying at 48 hours (P = .001) and 72 hours (P = .014) after reprocessing. CONCLUSIONS We demonstrate significantly fewer water droplets and delayed ATP bioluminescence values within endoscope working channels after automated drying compared with manual drying. In particular, virtually no retained fluid was evident within endoscope working channels after automated drying for 10 minutes. These findings support recommendations for automation of as many reprocessing steps as possible. Automated drying may decrease the risk of transmission of infection related to endoscopy.

Abstract
BACKGROUND & AIMS We have few population-level data on the performance of endoscopic retrograde cholangiopancreatography (ERCP) in the United States. We investigated the numbers of unplanned hospital encounters (UHEs), patient and facility factors associated with UHEs, and variation in quality and outcomes in the performance of ERCP in 3 large American states. METHODS We collected data on 68,642 ERCPs, performed at 635 facilities in California, Florida, and New York from 2009 through 2014. The primary endpoint was number of UHEs with an ERCP-related event within 7 days of ERCP; secondary endpoints included number of UHEs within 30 days and mortality within 30 days. Each facility was assigned a risk-standardized cohort, and variations in number of UHEs were analyzed with multivariable analysis. RESULTS Among all ERCPs, 5.8% resulted in a UHE within 7 days and 10.2% within 30 days. Performance of sphincterotomy was significantly associated with a higher risk of UHE at 7 and 30 days (P < .001). Younger age, female sex, and more advanced comorbidity were associated with UHE. There was substantial heterogeneity in rates of UHE among facilities: 4.2% at facilities in the 5th percentile and 25.2% at facilities in the 95th percentile. Increasing facility volume and ability to perform endoscopic ultrasonography were associated inversely with risk. The median number of ERCPs performed each year was 68.7, but 69% of facilities performed 100 or fewer ERCPs per year. Risk for UHE after sphincterotomy decreased with increasing facility volume until an inflection point of 157 ERCPs per year was reached. CONCLUSIONS In an analysis of outcomes of 68,642 ERCPs performed in 3 states, we found a higher-than-expected number of UHEs. There is substantial unexplained variation in risk for adverse events after ERCPs among facilities, and volume is the strongest predictor of risk. Annual facility volumes above approximately 150 ERCPs per year may protect against UHE.

Abstract
BACKGROUND AND AIMS Outbreaks of transmission of infection related to endoscopy despite reported adherence to reprocessing guidelines warrant scrutiny of all potential contributing factors. Recent reports from ambulatory surgery centers indicated widespread significant occult damage within endoscope working channels, raising concerns regarding the potential detrimental impact of this damage on the adequacy of endoscope reprocessing. METHODS We inspected working channels of all 68 endoscopes at our academic institution using a novel flexible inspection endoscope. Inspections were recorded and videos reviewed by 3 investigators to evaluate and rate channel damage and/or debris. Working channel rinsates were obtained from all endoscopes, and adenosine triphosphate (ATP) bioluminescence was measured. RESULTS Overall endoscope working channel damage was rated as minimal and/or mild and was consistent with expected wear and tear (median 1.59 on our 5-point scale). Our predominant findings included superficial scratches (98.5%) and scratches with adherent peel (76.5%). No channel perforations, stains, or burns were detected. The extent of damage was not predicted by endoscope age. Minor punctate debris was common, and a few small drops of fluid were noted in 42.6% of endoscopes after reprocessing and drying. The presence of residual fluid predicted higher ATP bioluminescence values. The presence of visualized working channel damage or debris was not associated with elevated ATP bioluminescence values. CONCLUSION The flexible inspection endoscope enables high-resolution imaging of endoscope working channels and offers endoscopy units an additional modality for endoscope surveillance, potentially complementing bacterial cultures and ATP values. Our study, conducted in a busy academic endoscopy unit, indicated predominately mild damage to endoscope working channels, which did not correlate with elevated ATP values.

Abstract
BACKGROUND & AIMS Fluoroscopy during endoscopic retrograde cholangiopancreatography (ERCP) is increasingly performed by therapeutic endoscopists, many of whom have not received formal training in modulating fluoroscopy use to minimize radiation exposure. Exposure to ionizing radiation has significant health consequences for patients and endoscopists. We aimed to evaluate whether a 20-minute educational intervention for endoscopists would improve use of fluoroscopy and decrease ERCP-associated exposure to radiation for patients. METHODS We collected data from 583 ERCPs, performed in California from June 2010 through November 2012; 331 were performed at baseline and 252 following endoscopist education. The educational intervention comprised a 20-minute video explaining best practices for fluoroscopy, coupled with implementation of a formal fluoroscopy time-out protocol before the ERCP was performed. Our primary outcome was the effect of the educational intervention on direct and surrogate markers of patient radiation exposure associated with ERCPs performed by high-volume endoscopists (HVEs) (200 or more ERCPs/year) vs low-volume endoscopists (LVEs) (fewer than 200 ERCPs/year). RESULTS At baseline, total radiation dose and dose area product were significantly higher for LVEs, but there was no significant difference between HVEs and LVEs following education. Education was associated with significant reductions in median fluoroscopy time (48% reduction for HVEs vs 30% reduction for LVEs), total radiation dose (28% reduction for HVEs vs 52% for LVEs) and dose area product (35% reduction for HVEs vs 48% reduction for LVEs). All endoscopists significantly increased their use of low magnification and collimation following education. CONCLUSIONS A 20-minute educational program with emphasis on ideal use of modifiable fluoroscopy machine settings results in an immediate and significant reduction in ERCP-associated patient radiation exposure for low-volume and high-volume endoscopists. Training programs should consider radiation education for advanced endoscopy fellows.

Abstract
BACKGROUND & AIMS Cholecystectomy (CCY) after an episode of choledocholithiasis requiring endoscopic retrograde cholangiopancreatography (ERCP) with stone extraction reduces recurrent biliary events compared to expectant management. We studied practice patterns for performance of CCY after ERCP for choledocholithiasis using data from 3 large states and evaluated the effects of delaying CCY. METHODS We conducted a retrospective cohort study using the ambulatory surgery, inpatient, and emergency department databases from the states of California (years 2009-2011), New York (2011-2013), and Florida (2012-2014). We collected data from 4516 patients hospitalized with choledocholithiasis who underwent ERCP. We compared outcomes of patients who underwent CCY at index admission (early CCY), elective CCY within 60 days of discharge (delayed CCY), or did not undergo CCY (no CCY), calculating rate of recurrent biliary events (defined as an emergency department visit or unplanned hospitalization due to symptomatic cholelithiasis, cholecystitis, choledocholithiasis, cholangitis, or biliary pancreatitis), mortality, and cost by CCY cohort. We also evaluated risk factors for not undergoing CCY. The primary outcome measure was the rate of recurrent biliary events in the 365 days after discharge from index admission. RESULTS Of the patients who underwent ERCP for choledocholithiasis, 41.2% underwent early CCY, 10.9% underwent delayed CCY, and 48.0% underwent no CCY. Early CCY reduced relative risk of recurrent biliary events within 60 days by 92%, compared with delayed or no CCY (P < .001). After 60 days following discharge from index admission, patients with early CCY had an 87% lower risk of recurrent biliary events than patients with no CCY (P < .001) and patients with delayed CCY had an 88% lower risk of recurrent biliary events than patients with no CCY (P < .001). A strategy of delayed CCY performed on an outpatient basis was least costly. Performance of early CCY was inversely associated with low facility volume. Hispanic race, Asian race, Medicaid insurance, and no insurance associated inversely with performance of delayed CCY. CONCLUSIONS In a retrospective analysis of >4500 patients hospitalized with choledocholithiasis, we found that CCY was not performed after ERCP for almost half of the cases. Although early and delayed CCY equally reduce the risk of subsequent recurrent biliary events, patients are at 10-fold higher risk of recurrent biliary event while waiting for a delayed CCY compared with patients who underwent early CCY. Delayed CCY is a cost-effective strategy that must be balanced against the risk of loss to follow-up, particularly among patients who are ethnic minorities or have little or no health insurance.
