Dupilumab in adolescent eosinophilic esophagitis: Experience with fibrostenosis and eosinophilic gastrointestinal disease with esophageal involvement.

We evaluated patients aged 12-20 on dupilumab 300 mg weekly for treatment of eosinophilic esophagitis (EoE) who had ≥1 follow-up endoscopy at a tertiary care pediatric hospital (n = 18). Fifty percent had inflammatory EoE (n = 9), 22% had fibrostenotic EoE (n = 4), and 28% had non-EoE eosinophilic gastrointestinal disease (EGID) with esophageal involvement (n = 5). Ninety-four percent discontinued topical corticosteroids (TCS) 2-4 weeks after starting dupilumab. Eighty-nine percent of inflammatory EoE patients had histological response (<15 eosinophils/high-powered field) after an average of 19.1 weeks. One hundred percent of patients with fibrostenotic disease exhibited histological response after 16.8 weeks. Of patients with non-EoE EGID, 60% achieved esophageal histological response after an average of 40.1 weeks. In a small cohort, dupilumab was very effective for adolescent inflammatory and fibrostenotic EoE despite rapid weaning of TCS. Dupilumab was also somewhat effective for non-EoE EGID with esophageal involvement; however, a longer duration of therapy was required.

Endoscopist experience with pediatric recurrent and intentional foreign body ingestion (RIFBI): Management considerations and future directions.

OBJECTIVES AND STUDY: Accidental foreign body ingestion (FBI) is a common pediatric referral concern. In contrast, recurrent and intentional FBI (RIFBI) is infrequent and associated with greater endoscopic and surgical intervention in adults. Although pediatric guidelines exist for FBI, the risk and therapeutic implications of RIFBI are not addressed. An anonymous international survey on pediatric gastroenterologist experience with RIFBI was distributed. METHODS: A 33-item REDCap© survey was distributed via email to pediatric gastroenterologists identified through mailing and email lists obtained from pediatric gastroenterology professional organizations. RESULTS: During 9-12/2021 we accrued 202 completed surveys. Respondents were from 27 countries and across the career span. Eighty percent reported experience with RIFBI; 74% reported seeing ≤ 3 patients with RIFBI within the past 24 months and 4% reported seeing ≥ 6. Of those who treated RIFBI, 38% reported an average number of annual ingestions per patient was ≥5. Frequent morbidity but not mortality was reported. Half reported adherence to FBI guidelines. Later-career endoscopists treated RIFBI more aggressively than accidental ingestion. Ninety-six percent noted that patients with RIFBI had psychiatric comorbidities. Providers at academic medical centers reported referring to behavioral health more than those in other settings. CONCLUSION: Most gastroenterologists surveyed reported encountering RFBI several times a year and in patients with psychiatric comorbidities. Greater likelihood of adverse outcomes associated with endoscopy was reported. Most reported referral to behavioral health and few had RIFBI management protocols. A broader spectrum of psychologic comorbidities in the pediatric population with RIFBI, notably depression and autism spectrum disorder, were reported.

Esophageal Dilation in Children: A State of the Art Review.

Esophageal dilations in children are performed by several pediatric and adult professionals. We aim to summarize improvements in safety and new technology used for the treatment of complex and refractory strictures, including triamcinolone injection, endoscopic electro-incisional therapy, topical mitomycin-C application, stent placement, functional lumen imaging probe assisted dilation, and endoscopic vacuum-assisted closure in the pediatric population.

Pediatric Aerodigestive Medicine: Advancing Collaborative Care for Children With Oropharyngeal Dysphagia.

OBJECTIVES: Aerodigestive disorders encompass various pathological conditions affecting the lungs, upper airway, and gastrointestinal tract in children. While advanced care has primarily occurred in specialty centers, many children first present to general pediatric gastroenterologists with aerodigestive symptoms necessitating awareness of these conditions. At the 2021 Annual North American Society for Pediatric Gastroenterology, Hepatology and Nutrition meeting, the aerodigestive Special Interest Group held a full-day symposium entitled, Pediatric Aerodigestive Medicine: Advancing Collaborative Care of Children with Aerodigestive Disorders. The symposium aimed to underline the significance of a multidisciplinary approach to achieve better outcomes for these complex patients. METHODS: The symposium brought together leading experts to highlight the growing aerodigestive field, promote new scientific and therapeutic strategies, share the structure and benefits of a multidisciplinary approach in diagnosing common and rare aerodigestive disorders, and foster multidisciplinary discussion of complex cases while highlighting the range of therapeutic and diagnostic options. In this article, we showcase the diagnostic and therapeutic approach to oropharyngeal dysphagia (OPD), one of the most common aerodigestive conditions, emphasizing the role of a collaborative model. CONCLUSIONS: The aerodigestive field has made significant progress and continues to grow due to a unique multidisciplinary, collaborative model of care for these conditions. Despite diagnostic and therapeutic challenges, the multidisciplinary approach has enabled and greatly improved efficient, high-quality, and evidence-based care for patients, including those with OPD.

Assessment of MRI and Ultrasound Screening for Tethered Cord Syndrome in Patients Diagnosed With Esophageal Atresia/Tracheoesophageal Fistula.

INTRODUCTION: Infants with esophageal atresia and/or tracheoesophageal fistula (EA/TEF) undergo screening for tethered cord syndrome (TCS) via ultrasound and magnetic resonance imaging. Existing literature lacks data to guide optimal timing of screening and magnetic resonance imaging (MRI) is often delayed until 3-6 mo of age, when it is frequently forgotten. Detethering surgery has a high rate of success in patients with TCS and is often performed prophylactically due to potential irreversible deficits. This study aims to improve screening procedure for infants with EA/TEF. METHODS: A retrospective chart review was done of all EA/TEF patients treated over 6 y (n = 79). The study examined how often each imaging modality was performed and identified a TCS lesion, as well as age of screening/surgical intervention. RESULTS: Screening for TCS was done with MRI 58% of the time and US 15% of the time. However, 38% of patients did not undergo any screening. Out of the patients with TCS on MRI (n = 19, 41.3%), 73.7% had neurosurgery. Of patients who underwent ultrasound (US) (n = 12), nine patients also had MRI later: two reported TCS lesions and subsequently had neurosurgery. Surgical infection rates and complications were 0/14. CONCLUSIONS: MRI demonstrated a higher rate of detecting TCS lesions than US, and patients with TCS frequently had detethering. Patients with ≥3 VACTERL or vertebral anomalies had a higher incidence of TCS on MRI. Patients with vertebral anomalies reported false negative ultrasounds in two cases, suggesting the potential superiority of MRI screening in this subgroup. A third of children did not undergo any imaging and this will require a process improvement.

Peroral Endoscopic Myotomy (POEM) in Children: A State of the Art Review.

Esophageal achalasia is a relatively rare disease in children that has been treated with balloon dilatation, botulinum toxin injection, and Heller myotomy. Peroral endoscopic myotomy (POEM) is another treatment that has been successfully employed to treat adults with achalasia for over a decade and has been increasingly used in children. This State of the Art Review from the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition Endoscopy Committee reviews the current literature in pediatric POEM including the technique, success rate, complications as well as training guidelines. Though there is limited data, POEM in children has shown encouraging success rates and with further study may become the mainstay of pediatric achalasia treatment.

Evolution of International Pediatric Endoscopic Practice Changes During the Coronavirus Disease 2019 Pandemic.

OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic has drastically altered endoscopic practices. We initially reported the international impact of COVID-19 on pediatric endoscopic practice. This follow-up study aimed to assess changes 7 months following the initial survey to delineate practice change patterns as the pandemic evolved. METHODS: Pediatric gastroenterologists who responded to the initial survey were re-surveyed seven months later using Research Electronic Data Capture (REDCap). The survey recorded information on changes in pediatric endoscopic practice patterns, including COVID-19 screening and testing processes and personal protective equipment (PPE) utilization. Additionally, endoscopists' risk tolerance of COVID-19 transmission was evaluated. RESULTS: Seventy-five unique institutions from 21 countries completed surveys from the 145 initial responses (51.7% response rate). Procedural volumes increased at most institutions (70.7%) and most were performing previously postponed cases (90.7%). Ninety-seven percent of institutions were performing pre-endoscopy screening with 78.7% testing all patients. Many institutions (34.7%) have performed procedures on COVID-19 positive patients. There was significantly less PPE reuse (P  < 0.05) and fewer institutions recommending full PPE for all endoscopies (43.2% vs 59.2%, P = 0.013). Overall, pediatric endoscopists' risk tolerance of COVID-19 transmission is low. CONCLUSIONS: This is the first survey to highlight the evolution of pediatric endoscopic practices related to the COVID-19 pandemic, underscoring the need for ongoing pandemic-related guidance for pediatric endoscopic practice.

Postpyloric Feeding Access in Infants and Children: A State of the Art Review.

Achieving postpyloric feeding access is a clinical challenge faced by the pediatric gastroenterologist in everyday practice. Currently, there is limited literature published on the topic. This article provides a practical summary of the literature on the different methods utilized to achieve postpyloric feeding access including bedside, fluoroscopic, endoscopic and surgical options. Indications and complications of these methods are discussed as well as a general approach to infants and children that require intestinal feeding.

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.

Pediatric Endoscopy in the Era of Coronavirus Disease 2019: A North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition Position Paper.

The delivery of endoscopic care is changing rapidly in the era of Coronavirus Disease 2019 (COVID-19). The North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN) Endoscopy and Procedures Committee has formulated this statement to offer practical guidance to help standardize endoscopy services for pediatric patients with the aim of minimizing COVID-19 transmission to staff, patients, and caregivers and to conserve personal protective equipment (PPE) during this critical time. Appropriate use of PPE is essential to minimize transmission and preserve supply. Pediatric endoscopic procedures are considered at high risk for COVID-19 transmission. We recommend that all pediatric endoscopic procedures are done in a negative pressure room with all staff using proper airborne, contact, and droplet precautions regardless of patient risk stratification. This includes appropriate use of a filtering face-piece respirator (N95, N99, FFP2/3, or PAPR), double gloves, facial protection (full visor and/or face shield), full body water-resistant disposable gown, shoe covers and a hairnet. In deciding which endoscopic procedures should proceed, it is important to weigh the risks and benefits to optimize healthcare delivery and minimize risk. To inform these decisions, we propose a framework for stratifying procedures as emergent (procedures that need to PROCEEED), urgent (PAUSE, weigh the benefits and risks in deciding whether to proceed) and elective (POSTPONE procedures). This statement was based on emerging evidence and is meant as a guide. It is important that all endoscopy facilities where pediatric procedures are performed follow current recommendations from public health agencies within their jurisdiction regarding infection prevention and control of COVID-19.

Mitigating Risks of Swallowed Button Batteries: New Strategies Before and After Removal.

Despite ongoing efforts of the national Button Battery Task Force (BBTF), cases of major morbidity and mortality continue to be reported at a higher rate after ingestion of higher voltage and larger button batteries. Initiation of sucralfate or honey shortly after some button battery ingestions is crucial to prevent further injury while awaiting emergent removal. Endoscopic acetic acid irrigation post removal of button battery may halt deeper injury. Gastroenterologists need to be aware of the updates to the National Capital Poison Center algorithm for button battery ingestion.

Efficacy and Safety of Carbon Dioxide Versus Air Insufflation for Colonoscopy in Deeply Sedated Pediatric Patients.

OBJECTIVES: Studies have shown the advantages of carbon dioxide (CO2) over air insufflation in the adult population during colonoscopies. This study was designed to investigate the efficacy and safety of CO2 insufflation in deeply sedated children undergoing colonoscopy. METHODS: This was a prospective, randomized, double-blind clinical trial. We recruited 100 consecutive pediatric patients who had colonoscopy under deep sedation for various indications. Patients were first randomized by history of abdominal pain and then randomly assigned to either CO2 or air insufflation. Postprocedural abdominal pain scores were registered on a 10-point visual analog rating scale and significant pain was defined as a score of 3 or higher. Abdominal circumferences and end tidal CO2 (ETCO2) levels were measured. Complications during and after the procedure were recorded. RESULTS: We did not find statistically significant difference between CO2 and air insufflation on univariate analysis because of low number of children experiencing significant pain after colonoscopy. After adjusting for baseline pain, we found that pain was significantly lower in patients after CO2 versus air insufflation on multivariable analysis (P = 0.03). The significant factors related to pain were duration of the procedure (P = 0.006), history of abdominal pain (P = 0.002) and previous abdominal surgery (P = 0.02). CO2 insufflation was associated with decreased abdominal circumference after colonoscopy (P = 0.002). Girls were more likely to have pain regardless of intervention (P = .04). CONCLUSIONS: Most children tolerate endoscopic procedures without significant pain. Our study was underpowered to show significant difference between air and CO2 on univariate analysis. CO2 insufflation during colonoscopy, however, may reduce postprocedural abdominal pain. Significant factors for increased pain on multivariate analysis included colonoscopy length over 30 minutes, history of abdominal pain, and previous abdominal surgery.

Quality Improvement in Pediatric Endoscopy: A Clinical Report From the NASPGHAN Endoscopy Committee.

The current era of healthcare reform emphasizes the provision of effective, safe, equitable, high-quality, and cost-effective care. Within the realm of gastrointestinal endoscopy in adults, renewed efforts are in place to accurately define and measure quality indicators across the spectrum of endoscopic care. In pediatrics, however, this movement has been less-defined and lacks much of the evidence-base that supports these initiatives in adult care. A need, therefore, exists to help define quality metrics tailored to pediatric practice and provide a toolbox for the development of robust quality improvement (QI) programs within pediatric endoscopy units. Use of uniform standards of quality reporting across centers will ensure that data can be compared and compiled on an international level to help guide QI initiatives and inform patients and their caregivers of the true risks and benefits of endoscopy. This report is intended to provide pediatric gastroenterologists with a framework for the development and implementation of endoscopy QI programs within their own centers, based on available evidence and expert opinion from the members of the NASPGHAN Endoscopy Committee. This clinical report will require expansion as further research pertaining to endoscopic quality in pediatrics is published.

NASPGHAN Capsule Endoscopy Clinical Report.

Wireless capsule endoscopy (CE) was introduced in 2000 as a less invasive method to visualize the distal small bowel in adults. Because this technology has advanced it has been adapted for use in pediatric gastroenterology. Several studies have described its clinical use, utility, and various training methods but pediatric literature regarding CE is limited. This clinical report developed by the Endoscopic and Procedures Committee of the North American Society of Pediatric Gastroenterology, Hepatology and Nutrition outlines the current literature, and describes the recommended current role, use, training, and future areas of research for CE in pediatrics.
