A National Survey of the Training and Practice Patterns of Practicing Pediatric Advanced Endoscopists in the United States.

BACKGROUND AND AIMS: Pediatric advanced endoscopy consists primarily of endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) and is becoming more common in pediatrics. This study aims to characterize the current landscape of pediatric advanced endoscopy training and practice by directly surveying independently practicing pediatric advanced endoscopists (PAEs). We also aim to ascertain expert opinion on competency in pediatric ERCP and EUS. METHODS: A 66-question REDCap survey and a 73-question Qualtrics survey were distributed to members of the ERCP Special Interest Group of North American Society of Pediatric Gastroenterology, Hepatology, and Nutrition. Respondents currently performing ERCP or EUS independently in children were included. Statistical analysis was performed using Mann-Whitney U test. RESULTS: Of 41 PAEs surveyed, 38 (92.7%) responded and 27 independent practitioners were included. Thirteen respondents performed EUS. PAEs who completed an advanced endoscopy fellowship (AEF) were more comfortable performing American Society for Gastrointestinal Endoscopy grade 3 or grade 4 ERCPs ( P < 0.0008) and felt more prepared to practice EUS independently than other trainees. Expert opinion of PAEs felt a threshold of 200 procedures was needed to attain competency in either ERCP or EUS. Pediatric duodenoscope exposure improved comfort in performing ERCP in children <10 kg ( P = 0.009). CONCLUSIONS: Training of pediatric gastroenterologists in ERCP and EUS are highly variable, though the skills attained are similar. AEF-trained specialists reported greater training volumes and felt more prepared to practice independently than those who did not. Competency thresholds determined by expert PAEs for ERCP and EUS agree with American Society for Gastrointestinal Endoscopy guidelines for adult advanced endoscopy trainees.

The Role of Endoscopy in the Management of Adolescent Bariatric Patients: A Primer For Pediatric Gastroenterologists.

PURPOSE OF REVIEW: The prevalence of childhood and adolescent obesity in the United States has reached alarming levels, necessitating effective interventions such as bariatric surgery. This article reviews the current state of bariatric surgery in the adolescent population, highlighting the common complications encountered in post-bariatric patients. Furthermore, it outlines the pivotal role of endoscopy in both the prevention and management of these bariatric complications. RECENT FINDINGS: Though only a minority of eligible adolescent patients undergo bariatric surgery the number of cases continues to increase. Sleeve gastrectomy has emerged as the preferred type of surgery, with the best balance of safety and efficacy. However, only a small number of pediatric surgeons have additional bariatric training and a number of technical aspects of the surgery itself impact the risk for post-surgical complications. Gastric sleeve stenosis, anastomotic leaks and gastroesophageal reflux are the most common of these complications. Ability to perform dilation of sleeve stenosis, closure of anastomotic leaks and evaluation of reflux are critical tools in the endoscopic toolbox necessary for the management of these complicated patients. Bariatric surgery remains the most effective treatment available for management of morbid obesity in adolescents but has significant associated complications. Pediatric gastroenterologists must be familiar in the endoscopic management of these complications and are crucial in creating a high functioning adolescent bariatric program.

Overview of the Pediatric Endoscopy Quality Improvement Network Quality Standards and Indicators for Pediatric Endoscopy: A Joint NASPGHAN/ESPGHAN Guideline.

INTRODUCTION: Pediatric-specific quality standards for endoscopy are needed to define best practices, while measurement of associated indicators is critical to guide quality improvement. The international Pediatric Endoscopy Quality Improvement Network (PEnQuIN) working group was assembled to develop and define quality standards and indicators for pediatric gastrointestinal endoscopic procedures through a rigorous guideline consensus process. METHODS: The Appraisal of Guidelines for REsearch and Evaluation (AGREE) II instrument guided PEnQuIN members, recruited from 31 centers of various practice types representing 11 countries, in generating and refining proposed quality standards and indicators. Consensus was sought via an iterative online Delphi process, and finalized at an in-person conference. Quality of evidence and strength of recommendations were rated according to the GRADE (Grading of Recommendation Assessment, Development, and Evaluation) approach. RESULTS: Forty-nine quality standards and 47 indicators reached consensus, encompassing pediatric endoscopy facilities, procedures, endoscopists, and the patient experience. The evidence base for PEnQuIN standards and indicators was largely adult-based and observational, and downgraded for indirectness, imprecision, and study limitations to "very low" quality, resulting in "conditional" recommendations for most standards (45/49). CONCLUSIONS: The PEnQuIN guideline development process establishes international agreement on clinically meaningful metrics that can be used to promote safety and quality in endoscopic care for children. Through PEnQuIN, pediatric endoscopists and endoscopy services now have a framework for auditing, providing feedback, and ultimately, benchmarking performance. Expansion of evidence and prospective validation of PEnQuIN standards and indicators as predictors of clinically relevant outcomes and high-quality pediatric endoscopic care is now a research priority.

Pediatric Endoscopy Quality Improvement Network Quality Standards and Indicators for Pediatric Endoscopy Facilities: A Joint NASPGHAN/ESPGHAN Guideline.

INTRODUCTION: There is increasing international recognition of the impact of variability in endoscopy facilities on procedural quality and outcomes. There is also growing precedent for assessing the quality of endoscopy facilities at regional and national levels by using standardized rating scales to identify opportunities for improvement. METHODS: With support from the North American and European Societies of Pediatric Gastroenterology Hepatology and Nutrition (NASPGHAN and ESPGHAN), an international working group of the Pediatric Endoscopy Quality Improvement Network (PEnQuIN) used the methodological strategy of the Appraisal of Guidelines for REsearch and Evaluation (AGREE) II instrument to develop standards and indicators relevant for assessing the quality of facilities where endoscopic care is provided to children. Consensus was reached via an iterative online Delphi process and subsequent in-person meeting. The quality of evidence and strength of recommendations were rated according to the GRADE (Grading of Recommendation Assessment, Development and Evaluation) approach. RESULTS: The PEnQuIN working group achieved consensus on 27 standards for facilities supporting pediatric endoscopy, as well 10 indicators that can be used to identify high-quality endoscopic care in children. These standards were subcategorized into three subdomains: Quality of Clinical Operations (15 standards, 5 indicators); Patient and Caregiver Experience (9 standards, 5 indicators); and Workforce (3 standards). DISCUSSION: The rigorous PEnQuIN process successfully yielded standards and indicators that can be used to universally guide and measure high-quality facilities for procedures around the world where endoscopy is performed in children. It also underscores the current paucity of evidence for pediatric endoscopic care processes, and the need for research into this clinical area.

Pediatric Endoscopy Quality Improvement Network Quality Standards and Indicators for Pediatric Endoscopic Procedures: A Joint NASPGHAN/ESPGHAN Guideline.

INTRODUCTION: High-quality pediatric gastrointestinal procedures are performed when clinically indicated and defined by their successful performance by skilled providers in a safe, comfortable, child-oriented, and expeditious manner. The process of pediatric endoscopy begins when a plan to perform the procedure is first made and ends when all appropriate patient follow-up has occurred. Procedure-related standards and indicators developed to date for endoscopy in adults emphasize cancer screening and are thus unsuitable for pediatric medicine. METHODS: With support from the North American and European Societies of Pediatric Gastroenterology Hepatology and Nutrition (NASPGHAN and ESPGHAN), an international working group of the Pediatric Endoscopy Quality Improvement Network (PEnQuIN) used the methodological strategy of the Appraisal of Guidelines for REsearch and Evaluation (AGREE) II instrument to develop standards and indicators relevant for assessing the quality of endoscopic procedures. Consensus was sought via an iterative online Delphi process and finalized at an in-person conference. The quality of evidence and strength of recommendations were rated according to the GRADE (Grading of Recommendation Assessment, Development, and Evaluation) approach. RESULTS: The PEnQuIN working group achieved consensus on 14 standards for pediatric endoscopic procedures, as well as 30 indicators that can be used to identify high-quality procedures. These were subcategorized into three subdomains: Preprocedural (3 standards, 7 indicators), Intraprocedural (8 standards, 18 indicators), and Postprocedural (3 standards, 5 indicators). A minimum target for the key indicator, "rate of adequate bowel preparation," was set at ≥80%. DISCUSSION: It is recommended that all facilities and individual providers performing pediatric endoscopy worldwide initiate and engage with the procedure-related standards and indicators developed by PEnQuIN to identify gaps in quality and drive improvement.

Pediatric Endoscopy Quality Improvement Network Quality Standards and Indicators for Pediatric Endoscopists and Endoscopists in Training: A Joint NASPGHAN/ESPGHAN Guideline.

INTRODUCTION: High-quality pediatric endoscopy requires reliable performance of procedures by competent individual providers who consistently uphold all standards determined to assure optimal patient outcomes. Establishing consensus expectations for ongoing monitoring and assessment of individual pediatric endoscopists is a method for confirming the highest possible quality of care for such procedures worldwide. We aim to provide guidance to define and measure quality of endoscopic care for children. METHODS: With support from the North American and European Societies of Pediatric Gastroenterology Hepatology and Nutrition (NASPGHAN and ESPGHAN), an international working group of the Pediatric Endoscopy Quality Improvement Network (PEnQuIN) used the methodological strategy of the Appraisal of Guidelines for REsearch and Evaluation (AGREE) II instrument to develop standards and indicators relevant for assessing the quality of endoscopists. Consensus was sought via an iterative online Delphi process and finalized at an in-person conference. The quality of evidence and strength of recommendations were rated according to the GRADE (Grading of Recommendation Assessment, Development, and Evaluation) approach. RESULTS: The PEnQuIN working group achieved consensus on 6 standards that all providers who perform pediatric endoscopy should uphold and 2 standards for pediatric endoscopists in training, with 7 corresponding indicators that can be used to identify high-quality endoscopists. Additionally, these can inform continuous quality improvement at the provider level. Minimum targets for defining high-quality pediatric ileocolonoscopy were set for 2 key indicators: cecal intubation rate (≥90%) and terminal ileal intubation rate (≥85%). DISCUSSION: It is recommended that all individual providers performing or training to perform pediatric endoscopy initiate and engage with these international endoscopist-related standards and indicators developed by PEnQuIN.

Pediatric Endoscopy Quality Improvement Network Pediatric Endoscopy Reporting Elements: A Joint NASPGHAN/ESPGHAN Guideline.

INTRODUCTION: High-quality procedure reports are a cornerstone of high-quality pediatric endoscopy as they ensure the clear communication of procedural events and outcomes, guide patient care and facilitate continuous quality improvement. The aim of this document is to outline standardized reporting elements that achieved international consensus as requirements for high-quality pediatric endoscopy procedure reports. METHODS: With support from the North American and European Societies of Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN and ESPGHAN), an international working group of the Pediatric Endoscopy Quality Improvement Network (PEnQuIN) used Delphi methodology to identify key elements that should be found in all pediatric endoscopy reports. Item reduction was attained through iterative rounds of anonymized online voting using a 6-point scale. Responses were analyzed after each round and items were excluded from subsequent rounds if ≤50% of panelists rated them as 5 ("agree moderately") or 6 ("agree strongly"). Reporting elements that ≥70% of panelists rated as "agree moderately" or "agree strongly" were considered to have achieved consensus. RESULTS: Twenty-six PEnQuIN group members from 25 centers internationally rated 63 potential reporting elements that were generated from a systematic literature review and the Delphi panelists. The response rates were 100% for all three survey rounds. Thirty reporting elements reached consensus as essential for inclusion within a pediatric endoscopy report. DISCUSSION: It is recommended that the PEnQuIN Reporting Elements for pediatric endoscopy be universally employed across all endoscopists, procedures and facilities as a foundational means of ensuring high-quality endoscopy services, while facilitating quality improvement activities in pediatric endoscopy.

Management of Pediatric Postendoscopy Fever: Reducing Unnecessary Health Care Utilization With a Clinical Care Guideline.

OBJECTIVES: The aim of the study was to validate rates of fever after pediatric gastrointestinal endoscopy, to describe clinical outcomes of postendoscopy fever (PEF) cases, and to assess the effect of a PEF clinical care guideline (CCG) on hospital use. PATIENTS AND METHODS: Episodes of PEF were reviewed from a large prospective database of all adverse events following pediatric gastrointestinal endoscopy at an academic children's hospital. A CCG was implemented to standardize care of children with reported fever after endoscopy and reduce unnecessary resource use. Chi-squared analysis was performed to compare rates of hospital use for evaluation of PEF before and after implementation of the CCG. RESULTS: PEF occurred in 0.55% of the 27,100 endoscopies performed during the present study period. In the 150 cases of reported fever, the rate of identified endoscopy-related infection was low (4.0%). The rate of PEF was significantly higher in patients who underwent interventional procedures (0.81%) than those who underwent diagnostic endoscopy (0.51%, P = 0.02). In patients who experienced PEF, the CCG significantly reduced hospital use, decreasing emergency department visits and hospital admissions by 52.1% (P < 0.0001) without leading to negative patient outcomes. CONCLUSION: PEF in children rarely represents clinically significant infection and may be due in part to inflammation from tissue damage and/or physiologic stress. The present study shows that implementation of a PEF CCG may reduce unnecessary care while maintaining patient safety. Furthermore, multicenter studies are required to confirm the overall safety of similar clinical algorithms.

Ketorolac Is Safe and Associated With Lower Rate of Post-Endoscopic Retrograde Cholangiopancreatography Pancreatitis in Children With Pancreatic Duct Manipulation.

OBJECTIVES: Use of non-steroidal anti-inflammatory drugs (NSAIDs) for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) prevention in pediatrics is not well studied. Because of difficulty in accurately dosing indomethacin suppositories in pediatric patients, our center has used intravenous ketorolac for PEP prevention and present data on its safety and associated PEP rates. METHODS: Prospective monitoring of PEP for all patients who underwent ERCP at a pediatric tertiary care center from July 2010 to June 2018. Retrospective review of patient and procedural factors and severity of PEP. Routine use of ketorolac for PEP prevention began in 2014. RESULTS: Two hundred and ninety-eight ERCPs were analyzed. One hundred and sixty-six patients received intraprocedural ketorolac and 132 did not. One patient had post-ERCP bleeding and bleeding rates were not significantly different between ketorolac and non-ketorolac groups (0.6% vs 0%, P = 1). Overall rates of PEP were not significantly different between the ketorolac and no ketorolac group (9% vs 13%, P = 0.29); however, for high-risk pediatric patients with injection of contrast into and/or cannulation of the pancreatic duct, the rates of PEP were significantly lower for patients who received ketorolac (11% vs 25%, P = 0.035). CONCLUSIONS: Pediatric patients undergoing ERCP with manipulation of the pancreatic duct are high risk for PEP, and ketorolac was associated with a lower rate of PEP in these patients. Ketorolac was well tolerated without a higher rate of bleeding after ERCP. These results are the first to provide evidence showing an association with intraprocedural NSAID use and lower rates of PEP in select pediatric patients.

Magnetic resonance imaging findings following button battery ingestion.

BACKGROUND: Lithium button battery ingestions have been increasing in frequency since the early 2000s and can develop severe and sometimes fatal complications from caustic injury even after rapid battery removal. To aid in clinical decision-making, we began obtaining magnetic resonance imaging (MRI)/MR angiography in these patients. OBJECTIVE: Our goal was to review MRI/MR angiography imaging in button battery ingestion cases and compare with other imaging, clinical data and outcomes in these patients. MATERIALS AND METHODS: In this retrospective institutional-review-board-approved study, we reviewed all button battery ingestion cases with MRI from April 2012 to September 2018. Clinical data, endoscopic findings and all imaging studies were rereviewed. MRIs were evaluated for inflammation, blooming artifact and complications including vascular injury, tracheoesophageal fistula, esophageal perforation and spondylodiscitis, and compared to endoscopy, esophagram and bronchoscopy. RESULTS: Twenty-three patients with button battery ingestions had a total of 51 MRI/MR angiograms. Seventy percent of the cohort was male with a median age of 2 years (range: 0.94-17 years). Severe complications were found in 48% of patients (11/23), including esophageal perforation (n=11), tracheoesophageal fistula (n=3) and spondylodiscitis (n=1). No patients had vascular injury. Cervical location of the battery was significantly associated with severe complications (10/11 cases). The length of the blooming artifact was greater than 2 cm in those with severe complications and, in most cases, <2 cm in those without severe complications. All complications were seen on initial screening MR exam with serial exams showing decreased inflammation. CONCLUSION: MRI/MR angiography can provide valuable information about complications, including esophageal perforation, tracheoesophageal fistula and spondylodiscitis. Decreasing inflammation surrounding the esophagus and vasculature is believed to be clinically reassuring and aids in managing button battery ingestion patients.

Results of duodenoscope culture and quarantine after manufacturer-recommended cleaning process.

BACKGROUND AND AIMS: Outbreaks of infections transmitted by duodenoscopes have prompted changes to duodenoscope cleaning protocols. However, little is known about effectiveness of clinical cleaning practices. We present culture data after duodenoscope manufacturer-recommended high-level disinfection (HLD) and quarantine. METHODS: Our institution adopted a combination of manufacturer-recommended cleaning with the Centers for Disease Control and Prevention-recommended culture and quarantine in 2015. Duodenoscopes (models TJF-Q180V, TJF-160, and PJF-160; Olympus, Center Valley, Penn, USA) underwent HLD according to the manufacturer's reprocessing manual protocols after use. Two culture specimens were then obtained using a sterile brush from the distal tip, including elevator mechanism, and by flushing sterile water through the working channel. Duodenoscopes were quarantined until cultures resulted. Positive cultures were defined as >10 colony-forming units (CFUs) of low-concern organisms or any CFUs of high-concern organisms according to Centers for Disease Control and Prevention recommendations. If either culture specimen was positive, the process was repeated until cultures were negative. Data were collected from December 2015 to July 2018. RESULTS: There were 140 instances of duodenoscope cleaning with 280 specimens. Twenty-eight of 234 (12%) initial culture specimens (18% of cultured duodenoscopes) were positive. Five of 36 (14%) second cultures were positive. Two of 8 (25%) third cultures were positive. Ninety-eight percent of organisms cultured were gram positive. In 8 instances both culture methods (brushing and flush) were positive; otherwise, only 1 method was positive. In 11 instances (8%) duodenoscopes were removed from quarantine before final culture results. No patient had infections related to ERCP. CONCLUSIONS: Eighteen percent of duodenoscopes had a positive culture after initial HLD. Only 3% were gram-negative bacteria. Repeated HLD was 86% and 75% effective at eliminating initial and repeat positive cultures, respectively. Initial HLD per manufacturer recommendations is not always effective at eliminating bacterial contamination. Additional steps are necessary to decrease risks of duodenoscope-transmitted infections.

Gastric injury secondary to button battery ingestions: a retrospective multicenter review.

BACKGROUND AND AIMS: Removal of gastric button batteries (BBs) remains controversial. Our aim was to better define the spectrum of injury and to characterize clinical factors associated with injury from retained gastric BBs. METHODS: In this multicenter retrospective cohort study from January 2014 through May 2018, pediatric gastroenterologists from 4 pediatric tertiary care centers identified patients, aged 0 to 18 years, who had a retained gastric BB on radiography and subsequently underwent endoscopic assessment. Demographic and clinical information were abstracted from electronic health records using a standard data collection form. RESULTS: Sixty-eight patients with a median age of 2.5 years underwent endoscopic retrieval of a gastric BB. At presentation, 17 (25%) were symptomatic. Duration from ingestion to endoscopic removal was known for 65 patients (median, 9 hours [interquartile range, 5-19]). Median time from ingestion to first radiographic evaluation was 2 hours. At endoscopic removal, 60% of cases had visual evidence of mucosal damage, which correlated with duration of BB retention (P = .0018). Time to retrieval of the BB was not statistically significant between symptomatic and asymptomatic subjects (P = .12). After adjusting for age and symptoms, the likelihood of visualizing gastric damage among patients who had BBs removed 12 hours post ingestion was 4.5 times that compared with those with BB removal within 12 hours of ingestion. CONCLUSIONS: In this study, swallowed BBs posed a risk of damage to the stomach, including a single case of impaction and perforation of the gastric wall. Clinicians may want to consider retrieval within 12 hours of ingestion of gastric BBs. Larger prospective studies to assess risk of injury are needed.

Transnasal Endoscopy in Unsedated Children With Eosinophilic Esophagitis Using Virtual Reality Video Goggles.

BACKGROUND & AIMS: Evaluation and treatment of children with eosinophilic esophagitis (EoE) requires serial endoscopic, visual, and histologic assessment by sedated esophagogastroduodenoscopy (EGD). Unsedated transnasal endoscopy (TNE) was reported to be successful in a pilot study of children. We evaluated video goggle and virtual reality-based unsedated TNE in children with EoE, collecting data on rates of completion, adverse events, and adequacy of visual and histologic findings. METHODS: We performed a retrospective study of 190 children and young adults (age, 3-22 y) who underwent video goggle or virtual reality-based unsedated TNE from January 2015 through February 2018. We analyzed data on patient demographics, procedure completion, endoscope type, adverse events, visual and histologic findings, estimated costs, and duration in the facility. Esophageal biopsies from the first 173 subjects who underwent TNE were compared with those from previous EGD evaluations. RESULTS: During 300 attempts, 294 TNEs were performed (98% rate of success). Fifty-four patients (age, 6-18 y) underwent multiple TNEs for dietary or medical management of EoE. There were no significant adverse events. Visual and histologic findings were adequate for assessment of EoE. TNE reduced costs by 53.4% compared with EGD (TNE $4393.00 vs EGD $9444.33). TNE was used increasingly from 2015 through 2017, comprising 31.8% of endoscopies performed for EoE. The total time spent in the clinic (front desk check-in to check-out) in 2018 was 71 minutes. CONCLUSIONS: In a retrospective study of 190 children and young adults (age, 3-22 y) who underwent video goggle or virtual reality-based unsedated TNE, TNE was safe and effective and reduced costs of EoE monitoring. Advantages of TNE include reduced risk and cost associated with anesthesia as well as decreased in-office time, which is of particular relevance for patients with EoE, who require serial EGDs.

Comparative Analysis of Adverse Events After Esophageal Balloon and Bougie Dilations in Children.

BACKGROUND: Pneumatic balloon and bougie dilation are widely used methods for pediatric esophageal dilation. There are no studies directly comparing the safety of these techniques in pediatric patients. This study compared adverse events (AEs) of balloon and bougie dilation in children at a single institution. METHODS: AEs were identified by means of a prospective clinical registry of all procedure related AEs from 2012 to 2015 at a single institution. Identified AEs underwent retrospective review of procedural and clinical details. The category of each AE was recorded and severity was assigned using a 5-point scoring system. AEs were compared between balloon and bougie dilation for different severities. RESULTS: There were 105 patients who underwent 246 dilation sessions. Balloon dilation was performed more commonly (n = 190, 77%) as compared to Maloney dilators (n = 56, 23%). Patients with balloon dilation were younger (3.0 vs 14.5 years, P = 0.0001) and more likely to have strictures from caustic ingestion (42% vs 2%, P < 0.0001) or surgical anastomoses (34% vs 5% P < 0.0001). Bougie dilation was used more commonly in patients with eosinophilic esophagitis (77% vs 7%, P < 0.0001)). In multivariate analysis, each year of increasing age was associated with a 12% increase in any AEs (P = 0.015), but no difference in clinically significant AEs (grade 2 or higher) was identified between dilation methods. CONCLUSIONS: Bougie and balloon dilation did not have significant differences in AE rates, but the patient populations differed between the 2 methods. The dilation method should depend on stricture characteristics and endoscopist expertise with each method.

Impact of fellow training level on adverse events and operative time for common pediatric GI endoscopic procedures.

BACKGROUND AND AIMS: Previous studies on pediatric endoscopic training have not examined in detail if adverse events (AEs) are affected by the fellow's training level. We aimed to determine whether trainee presence and educational level increase AEs or operative time (OT) for pediatric intestinal endoscopy. METHODS: This was a prospective observational study of AEs for all endoscopic procedures and retrospective analysis of OT (time of endoscope insertion until removal) for a sample of specified procedures at a tertiary children's hospital. AEs were categorized by severity grades: 1, home management; 2, outpatient evaluation; 3, hospitalization and/or repeat endoscopy; 4, surgery and/or intensive care unit admission; and 5, death. RESULTS: A total of 15,886 procedures (6257 with trainee) including 1627 therapeutic procedures (733 with trainee) were analyzed for AEs. Four hundred thirteen total AEs (2.60%) and 213 AEs grade 2 to 4 (1.34%) were identified. Fellow presence at any training level did not increase AE rates for any procedures. Median OT for 3762 EGDs decreased from 17 to 11 minutes from the first quarter to the fourth quarter of first-year fellowship and then remained stable. EGDs without fellows were shorter (9 minutes, P < .0001) compared with any training level. Median times of 1291 colonoscopies with EGD decreased from 55 to 51 to 47 minutes for fellows in the first half, second half of first-year fellowship, and second and third year, respectively. Attendings alone were faster (37 minutes, P < .0001). CONCLUSIONS: Current pediatric endoscopic training for is safe regardless of fellow training level. Trainee efficiency improves during and after fellowship.

Use of Fully Covered Self-expanding Metal Biliary Stents in Pediatrics: A Case Series.

OBJECTIVES: Endoscopic retrograde cholangiopancreatography is used to manage biliary pathology in pediatric patients. Plastic biliary stents have been used in this population for obstructive lesions and bile leaks; however, they are sometimes not effective due to migration, occlusion, or ineffective sealing. Fully covered self-expanding metal stents (FCSEMS) have larger diameters making them more suitable for some situations. Their use in pediatrics has, however, not been defined. The aim of the present study is to describe our experience with FCSEMS at our institution. METHODS: We present a series of all patients who underwent FCSEMS placement at Children's Hospital Colorado including 3 adolescents and 1 young adult with complex medical needs. RESULTS: Patient age range was 12 to 24 years and the weight ranged between 36 and 75 kg. All patients underwent previous endoscopic retrograde cholangiopancreatography and 1 or more rounds of plastic stenting without adequate clinical response before consideration of FCSEMS placement. Indications included recalcitrant biliary anastomotic stricture after liver transplant, persistent bile leak after needle perforation, recurrent obstructive choledocholithiasis after cholecystectomy, and malignant biliary stricture. Sizes of FCSEMS depended on patient bile duct size and biliary pathology. Dwell time was 6 to 8 weeks. Three patients had resolution of biliary pathology after FCSEMS therapy. One patient had distal migration of FCSEMS necessitating repeat stenting. There were no adverse events from FCSEMS placement or removal. CONCLUSIONS: FCSEMS therapy should be considered in appropriate pediatric patients when plastic biliary stents are not effective. Further studies are needed to evaluate the safety and efficacy of FCSEMS in the pediatric age group.

Approach and Safety of Esophageal Dilation for Treatment of Strictures in Children With Epidermolysis Bullosa.

OBJECTIVE: The aim of the study is to analyze a large series of esophageal balloon dilations in patients with epidermolysis bullosa (EB) to determine procedural approach and frequency of post-endoscopic adverse events (AEs). METHODS: Retrospective chart review for AE occurrence and clinical outcomes in children and adolescents with EB, age 1 to 19, who underwent esophageal dilation for esophageal stricture(s) from January 2003 to April 2016 at an academic, tertiary care, free-standing children's hospital. The primary outcome measure was occurrence of procedural AEs (defined as events occurring within 72 hours after endoscopic dilation procedure). RESULTS: A total of 231 fluoroscopy-guided esophageal balloon dilation procedures (209 anterograde, 20 retrograde, 2 both) were performed in 24 patients. Strictures were more common in the proximal portion of the esophagus with median stricture location 13 cm from the lips. From 2003 to 2012, 4.1% of dilations were retrograde. From 2013 to 2016, 20.2% of dilations were retrograde. AEs attributable to dilation occurred after 10.0% of procedures, and the most common AEs were vomiting, pain, and fever. No esophageal perforations, serious bleeding events, or deaths occurred secondary to dilation. The rate of post-dilation hospitalization was 6.9%. Dilation approach (anterograde vs retrograde) did not impact the likelihood of AEs. CONCLUSIONS: The characteristic esophageal lesion in EB is a single, proximal esophageal stricture. EB patients can safely undergo repeat pneumatic esophageal balloon dilations with minimal risk for severe complication. We observed a trend towards increased use of retrograde esophageal dilation.

Button Battery Powered Fidget Spinners: A Potentially Deadly New Ingestion Hazard for Children.

Toys entering the marketplace may have unrecognized hazard risks until data on injury become known. The fidget spinner is a new popular toy mass marketed to children and is primarily sold without warning labels. The US Consumer Product Safety Commission has recently issued a formal statement on potential safety concerns related to ingestion of the toy parts and other hazards. Button batteries within this toy pose the greatest danger to children as ingestion can lead to lethal injury. We report 2 cases of children who swallowed a button battery from a fidget spinner, causing severe esophageal injury. Various aspects of this type of ingestion important for clinicians to be aware of are reviewed.

Unsedated In-office Transgastrostomy Esophagoscopy to Monitor Therapy in Pediatric Esophageal Disease.

Monitoring therapy in esophageal inflammatory disorders such as eosinophilic esophagitis and reflux esophagitis often requires frequent endoscopic evaluation. We recently reported the effective use of unsedated in-office transnasal esophagoscopy that significantly decreased costs and anesthetic exposure associated with pediatric esophagoscopy in eosinophilic esophagitis. Here we report a series of pediatric patients with esophagitis with gastrostomy tubes who underwent unsedated transgastrostomy esophagoscopy (TGE) in an office setting. Nine patients (ages 16 months-21 years) tolerated TGE without significant adverse events. Biopsy specimens were adequate for evaluation. This series confirms that unsedated in-office TGE can be used to successfully obtain mucosal biopsies to monitor esophageal inflammatory conditions in children without the use of sedation.
