RESUMO
BACKGROUND: The cause of duodenal atresia (DA) is not known. Tandler's "solid cord" hypothesis conflicts with current biological evidence. In humans, a genetic aetiology is supported by the association with Trisomy 21. Interruption of Fgf10 is the strongest genetic link to DA in mice, demonstrating an increased incidence and severity as embryos mature. This project aimed to develop an organoid model to facilitate ex vivo DA research on the FGF10/FGFR2b signalling pathway. We hypothesised that DA morphology represents an evolving spectrum of disease and that Fgf10 knockout organoids would vary in growth pattern compared to wild-type. METHODS: Organoids were cultured from the duodenum of E12.5 Fgf10 knockout, heterozygous and wild-type embryos, using an air-liquid interface with Growth Factor reduced Matrigel. Organoids were photographed every 48 h to observe growth. Organoids were isolated and fixed after 14 days, then stained with DAPI, KI-67, and cytokeratin to demonstrate proliferation and differentiation. RESULTS: Wild-type duodenum developed into crypt-forming organoids. Fgf10 heterozygous duodenum failed to progress beyond the development stage of spheroids. Fgf10 knockout duodenum failed to demonstrate any growth. Wholemount staining showed the greatest cell proliferation and differentiation in wild-type tissue. CONCLUSION: This research presents a novel concept for the growth of embryonic gastrointestinal tissue to inform normal biology. The small sample numbers and restricted culture duration limit longer-term growth analysis. While this model serves as a potential ex vivo setting for future research, that research should consider organoid models with greater standardisation and other gastrointestinal regions. LEVEL OF EVIDENCE: Animal/laboratory study.
RESUMO
OBJECTIVES: Using high resolution impedance manometry (HRIM), this study characterized the esophago-gastric junction (EGJ) dynamics in children with esophageal atresia (EA). METHOD: Esophageal HRIM was performed in patients with EA aged less than 18 years. Objective motility patterns were analyzed, and EGJ data reported. Controls were pediatric patients without EA undergoing investigations for consideration of fundoplication surgery. RESULTS: Seventy-five patients (M:F = 43:32, median age 1 year 3 months [3 months-17 years 4 months]) completed 133 HRIM studies. The majority (64/75, 85.3%) had EA with distal tracheo-esophageal fistula. Compared with controls, liquid swallows were poorer in patients with EA, as evident by significant differences in distension pressure emptying and bolus flow time (BFT). The integrated relaxation pressure for thin liquid swallows was significantly different between EA types, as well as when comparing patients with EA with and without previous esophageal dilatations. The BFT for solid swallows was significantly different when compared with EA types. CONCLUSIONS: We have utilized HRIM in patients with EA to demonstrate abnormalities in their long-term EGJ function. These abnormalities correlate with poorer esophageal compliance and reduced esophageal peristalsis across the EGJ. Understanding the EGJ function in patients with EA will allow us to tailor long-term management to specific patients.

BACKGROUND: Despite surgical advances for complex congenital colorectal conditions, such as anorectal malformation (ARM) and Hirschsprung disease (HD), many adolescents require transfer from specialist pediatric to adult providers for ongoing care. METHODOLOGY: A systematic review of PubMed, MEDLINE and Embase was conducted to identify what is known about the transitional care of patients with ARM and HD (PROSPERO # CRD42022281558). The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework guided our reporting of studies that focused on the transition care of 10-30-year-olds with ARM and HD. RESULTS: Eight studies were identified that included patient and parent (n = 188), and/or clinician perspectives (n = 334). Patients and clinicians agreed that transitional care should commence early in adolescence to support transfer to adult care when a suitable level of maturation is reached. There was little evidence from patients that transfer happened in a timely or coordinated manner. Patients felt that clinicians did not always understand the significance of transfer to adult services. No models of transition care were identified. Surgeons ranked ARM and HD as the most common conditions to experience delayed transfer to adult care. Beyond pediatric surgeons, patients also highlighted the importance of general practitioners, transitional care coordinators and peer support groups for successful transition. CONCLUSIONS: There is little research focused on transitional care for patients with ARM and HD. Given evidence of delayed transfer and poor experiences, the development of models of transitional care appears essential.

Background: Mechanosensation is an important trigger of physiological processes in the gastrointestinal tract. Aberrant responses to mechanical input are associated with digestive disorders, including visceral hypersensitivity. Transient Receptor Potential Vanilloid 4 (TRPV4) is a mechanosensory ion channel with proposed roles in visceral afferent signaling, intestinal inflammation, and gut motility. While TRPV4 is a potential therapeutic target for digestive disease, current mechanistic understanding of how TRPV4 may influence gut function is limited by inconsistent reports of TRPV4 expression and distribution. Methods: In this study we profiled functional expression of TRPV4 using Ca2+ imaging of wholemount preparations of the mouse, monkey, and human intestine in combination with immunofluorescent labeling for established cellular markers. The involvement of TRPV4 in colonic motility was assessed in vitro using videomapping and contraction assays. Results: The TRPV4 agonist GSK1016790A evoked Ca2+ signaling in muscularis macrophages, enteric glia, and endothelial cells. TRPV4 specificity was confirmed using TRPV4 KO mouse tissue or antagonist pre-treatment. Calcium responses were not detected in other cell types required for neuromuscular signaling including enteric neurons, interstitial cells of Cajal, PDGFRα+ cells, and intestinal smooth muscle. TRPV4 activation led to rapid Ca2+ responses by a subpopulation of glial cells, followed by sustained Ca2+ signaling throughout the enteric glial network. Propagation of these waves was suppressed by inhibition of gap junctions or Ca2+ release from intracellular stores. Coordinated glial signaling in response to GSK1016790A was also disrupted in acute TNBS colitis. The involvement of TRPV4 in the initiation and propagation of colonic motility patterns was examined in vitro. Conclusions: We reveal a previously unappreciated role for TRPV4 in the initiation of distension-evoked colonic motility. These observations provide new insights into the functional role of TRPV4 activation in the gut, with important implications for how TRPV4 may influence critical processes including inflammatory signaling and motility.
RESUMO
PURPOSE: The lifelong impact of Hirschsprung disease (HD) upon children and their families is increasingly well recognized. Parental psychosocial wellbeing and family functioning are determinants of psychological and health-related outcomes in children with chronic conditions. We performed a cross-sectional cohort study to evaluate the psychosocial functioning of parents/caregivers of children with HD, beyond early childhood. METHODS: Parents/caregivers of children with HD, aged 4-14 years, managed at a tertiary pediatric surgical center were surveyed. Parent psychosocial outcomes, including adjustment to illness and family response, were assessed using four validated measures: Family Management Measure (FaMM); Parent Experience of Child Illness (PECI); Patient Reported Outcomes Measurement Information System (PROMISR) anxiety; and PROMISR depression. The Pediatric Quality of Life Inventory (PedsQL) was administered to assess child quality of life (proxy-report). RESULTS: Forty parents (mean age 38.7 ± 5.6 years) of children with HD (mean age 8.0 ± 2.5) participated. Parents expressed greater long-term uncertainty (PECI) and poorer perceived condition management ability (FaMM) than comparator chronic disease cohorts. Other scores for parental adjustment to their child's condition (PECI) and family response (FaMM) were comparable to reference cohorts. Symptoms of anxiety and depression were prevalent in our cohort (52.5 % and 42.5 % respectively); however, the proportion with moderate - severe PROMISR anxiety (χ2 = 2.50, p = 0.114) and depression (χ2 = 0.156, p = 0.693) scores did not significantly differ from the expected population distribution. Proxy-reported child quality of life (PedsQL) was significantly reduced relative to healthy children (p = 0.0003), but comparable to those with physical health problems with special healthcare needs (p = 0.624). CONCLUSIONS: Parents of children with HD experience long-term uncertainty and have poorer perceived condition management ability than parents of children with other chronic childhood illnesses. This work highlights the importance of targeted parental education and support beyond primary surgical management, and provides a benchmark for this cohort, against which subsequent intervention-based studies may be assessed. LEVEL OF EVIDENCE: II.

PURPOSE: Chronic diseases are notorious in the way that they interfere with many aspects of a child's development, and this holds true for children with Hirschsprung disease (HD). The present research aims to (1) determine whether the health-related quality of life (HRQoL) of HD children differs from healthy paediatric populations; and (2) explore the relationship between HD children's HRQoL and psychosocial outcomes of parents. METHODS: Using a cross-sectional survey study design, children's HRQoL was assessed using the Pediatric Quality of Life Inventory (PedsQL), while parental psychosocial outcomes were measured using the Patient-Reported Outcomes Measurement Information System (PROMIS) anxiety and depression short-forms, Family Management Measure (FaMM), and Parent Experience of Child Illness. Surveys were administered over telephone to parents of 48 Australian children treated for HD (87.5% male, median age 4.5 years) during the period May to November 2021. RESULTS: While postoperative HRQoL of HD children was comparable to that of healthy age-matched controls, psychosocial quality of life of HD children was significantly poorer (mean difference = 3.40, CI [0.05, 6.76]). All parental outcome measures were significantly correlated with the PedsQL (r = - 0.77-0.67, p < 0.05) in expected directions, with FaMM subscales (except parent mutuality) demonstrating the most variation (R2 = 0.41-0.59). Of note, 31.3% of parents reported moderate to severe symptoms of anxiety on the PROMIS. CONCLUSION: Despite overall positive results for children, parents reported elevated symptoms of anxiety. This study highlights the importance of long-term follow-up care for HD patients and their families.

Patient registries serve to overcome the research limitations inherent in the study of rare diseases, where patient numbers are typically small. Despite the value of real-world data collected through registries, adequate design and maintenance are integral to data quality. We aimed to describe an overview of the challenges in design, quality management, and maintenance of rare disease registries.A systematic search of English articles was conducted in PubMed, Ovid Medline/Embase, and Cochrane Library. Search terms included "rare diseases, patient registries, common data elements, quality, hospital information systems, and datasets". Inclusion criteria were any manuscript type focused upon rare disease patient registries describing design, quality monitoring or maintenance. Biobanks and drug surveillances were excluded.A total of 37 articles, published between 2001 and 2021, met the inclusion criteria. Patient registries covered a wide range of disease areas and covered multiple geographical locations, with a predisposition for Europe. Most articles were methodological reports and described the design and setup of a registry. Most registries recruited clinical patients (92%) with informed consent (81%) and protected the collected data (76%). Whilst the majority (57%) collected patient-reported outcome measures, only few (38%) consulted PAGs during the registry design process. Few reports described details regarding quality management (51%) and maintenance (46%).Rare disease patient registries are valuable for research and evaluation of clinical care, and an increasing number have emerged. However, registries need to be continuously evaluated for data quality and long-term sustainability to remain relevant for future use.

Despite surgical correction, children with anorectal malformations may experience long-term bowel dysfunction, including fecal incontinence and/or disorders of evacuation. Anorectal manometry is the most widely used test of anorectal function. Although considerable attention has been devoted to its application in the anorectal malformation cohort, there have been few attempts to consolidate the findings obtained. This systematic review aimed to (1) synthesize and evaluate the existing data regarding anorectal manometry results in children following anorectal malformation repair, and (2) evaluate the manometry protocols utilized, including equipment, assessment approach, and interpretation. We reviewed four databases (Embase, MEDLINE, the Cochrane Library, and PubMed) for relevant articles published between 1 January 1985 and 10 March 2022. Studies reporting post-operative anorectal manometry in children (<18 years) following anorectal malformation repair were evaluated for eligibility. Sixty-three studies were eligible for inclusion. Of the combined total cohort of 2155 patients, anorectal manometry results were reported for 1755 children following repair of anorectal malformations. Reduced resting pressure was consistently identified in children with anorectal malformations, particularly in those with more complex malformation types and/or fecal incontinence. Significant variability was identified in relation to manometry equipment, protocols, and interpretation. Few studies provided adequate cohort medical characteristics to facilitate interpretation of anorectal manometry findings within the context of the broader continence mechanism. This review highlights a widespread lack of standardization in the anorectal manometry procedure used to assess anorectal function in children following anorectal malformation repair. Consequently, interpretation and comparison of findings, both within and between institutions, is exceedingly challenging, if not impossible. Standardized manometry protocols, accompanied by a consistent approach to analysis, including definitions of normality and abnormality, are essential to enhance the comparability and clinical relevance of results.
RESUMO
BACKGROUND: Registries are important in rare disease research. The Anorectal Malformation Network (ARM-Net) registry is a well-established European patient registry collecting demographic, clinical, and functional outcome data. We assessed the quality of this registry through review of the structure, data elements, collected data, and user experience. MATERIAL AND METHODS: Design and data elements were assessed for completeness, consistency, usefulness, accuracy, validity, and comparability. An intra- and inter-user variability study was conducted through monitoring and re-registration of patients. User experience was assessed via a questionnaire on registration, design of registry, and satisfaction. RESULTS: We evaluated 119 data elements, of which 107 were utilized and comprised 42 string and 65 numeric elements. A minority (37.0%) of the 2278 included records had complete data, though this improved to 83.5% when follow-up elements were excluded. Intra-observer variability demonstrated 11.7% incongruence, while inter-observer variability was 14.7%. Users were predominantly pediatric surgeons and typically registered patients within 11-30 min. Users did not experience any significant difficulties with data entry and were generally satisfied with the registry, but preferred more longitudinal data and patient-reported outcomes. CONCLUSIONS: The ARM-Net registry presents one of the largest ARM cohorts. Although its collected data are valuable, they are susceptible to error and user variability. Continuous evaluations are required to maintain relevant and high-quality data and to achieve long-term sustainability. With the recommendations resulting from this study, we call for rare disease patient registries to take example and aim to continuously improve their data quality to enhance the small, but impactful, field of rare disease research.

PURPOSE: The majority of patients with an anorectal malformation (ARM) have associated congenital anomalies. It is well established that all patients diagnosed with an ARM should undergo systematic screening, including renal, spinal, and cardiac imaging. This study aimed to evaluate the findings and completeness of screening, following local implementation of standardized protocols. METHODS: A retrospective cohort study was performed assessing all patients with an ARM managed at our tertiary pediatric surgical center, following a standardized protocol implementation for VACTERL screening (January 2016-December 2021). Cohort demographics, medical characteristics, and screening investigations were analyzed. Findings were compared with our previously published data (2000-2015), conducted prior to protocol implementation. RESULTS: One hundred twenty-seven (64 male, 50.4%) children were eligible for inclusion. Complete screening was performed in 107/127 (84.3%) children. Of these, one or more associated anomalies were diagnosed in 85/107 (79.4%), whilst the VACTERL association was demonstrated in 57/107 (53.3%). The proportion of children that underwent complete screening increased significantly in comparison with those assessed prior to protocol implementation (RR 0.43 [CI 0.27-0.66]; p < 0.001). Children with less complex ARM types were significantly less likely to receive complete screening (p = 0.028). Neither presence of an associated anomaly, nor prevalence of the VACTERL association, differed significantly by ARM type complexity. CONCLUSION: Screening for associated VACTERL anomalies in children with ARM was significantly improved following standardized protocol implementation. The prevalence of associated anomalies in our cohort supports the value of routine VACTERL screening in all children with ARM, regardless of malformation type. LEVEL OF EVIDENCE: II.

Esophageal dysmotility in esophageal atresia (EA) relates to abnormal development of esophageal innervation and musculature and to the esophageal repair. Few studies have investigated the preexisting dysmotility in EA, present prior to surgery. This systematic review aims to summarize the literature on neuronal studies in EA, to understand the causative factors for esophageal dysmotility. We performed a systematic review (PubMed, EMBASE, EBM, CINAHL databases; January 1947-February 2021) in accordance with PRISMA (PROSPERO number CRD42020171014). Fourteen studies were identified (eleven human, 187 EA patients; three animal, 64 EA rat specimens). Neural factors affecting esophageal dysmotility in human and animal studies included proteins, enzymes, growth factors, and genes, which play a role in the nervous system or neuroendocrine system, some of which have functions as neuromodulators or neurotransmitters. This systematic review has identified neural factors that affect esophageal dysmotility and contributes toward our understanding of the underlying dysmotility in patients with EA. The studies identified are important and essential for successful translation of basic science knowledge to impact clinical practice and understanding. Level of evidence: III.

Anorectal malformations occur in 1 in 3000 to 5000 children, and present with a marked variety in type and severity. Most of the malformations are diagnosed in the early neonatal period, as an antenatal diagnosis remains relatively elusive. Following diagnosis, an accurate assessment and focused management is crucial to reduce the potential for morbidity and mortality. This review focuses on the investigation and management of newborns with anorectal malformations, and the introduction of novel assessment tools for the more complex malformation types.

Hirschsprung disease (HSCR) is characterised by the absence of enteric ganglia along variable lengths of the distal bowel. Current gold standard treatment involves the surgical resection of the defective, aganglionic bowel. Clear and reliable distinction of the normoganglionated bowel from the transition zone is key for successful resection of the entire defective bowel, and the avoidance of subsequent postoperative complications. However, the intraoperative nature of the tissue analysis and the variability of patient samples, sample preparation, and operator objectivity, make reproducible identification of the transition zone difficult. Here, we have described a novel method for using muscle units as a distinctive landmark for quantifying the density of enteric ganglia in resection specimens from HSCR patients. We show that the muscle unit to ganglion ratio is greater in the transition zone when compared with the proximal, normoganglionated region for long-segment HSCR patients. Patients with short-segment HSCR were also investigated, however, the muscle unit to ganglion ratio was not significantly different in these patients. Immunohistochemical examination of individual ganglia showed that there were no differences in the proportions of either enteric neurons or glial cells through the different regions of the resected colon. In addition, we identified that the size of enteric ganglia was smaller for patients that went on to develop HSCR associated enterocolitis; although the density of ganglia, as determined by the muscle unit to ganglia ratio, was not different when compared with patients that had no further complications. This suggests that subtle changes in the enteric nervous system, even in the "normoganglionated" colon, could be involved in changes in immune function and subsequent bacterial dysbiosis.

BACKGROUND: Children with anorectal malformations may experience constipation and fecal incontinence following repair. The contribution of altered anorectal function to these persistent symptoms is relatively intuitive; however, colonic motility in this cohort is less well understood. Manometry may be used to directly assess colonic motility. PURPOSE: The purpose of this systematic review was to synthesize the available evidence regarding post-operative colonic motility in children with anorectal malformations and evaluate the reported equipment and protocols used to perform colonic manometry in this cohort. This systematic review was conducted in compliance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). We conducted a systematic review of four databases: Embase, MEDLINE, PubMed, and the Cochrane Library (1st January 1985-22nd July 2021). Studies reporting colonic manometry performed in children following anorectal malformation repair were assessed for eligibility. Data were extracted independently by two authors. Four studies were eligible for inclusion. Of the combined total cohort of 151 children, post-operative colonic manometry was conducted in 35. Insufficient reporting of medical characteristics, bowel function, and manometric outcomes restricted comparison between studies, and limited clinical applicability. No results from high-resolution colonic manometry were identified. Despite the prevalence of post-operative bowel dysfunction in children with repaired anorectal malformations, this systematic review highlighted the markedly limited evidence regarding post-operative colonic motility. This cohort may benefit from assessment with high-resolution techniques; however, future work must emphasize adherence to standardized manometry protocols, and include robust reporting of surgical characteristics, bowel function, and manometric outcomes.

BACKGROUND: Opioids play a major role in postoperative pain management in children, but their administration remains an under investigated topic. This study aimed to describe perioperative opioid prescribing practices for paediatric inguinal hernia patients in the literature and at The Royal Children's Hospital (RCH) in Melbourne, Australia. MATERIAL/METHOD: A systematic review of English articles (published from 2009 to 2019) was conducted on paediatric (0-18y) inguinal hernia patients who received a postoperative or discharge opioid prescription, or both. The review was combined with a retrospective audit of RCH patients. Demographic, surgical, and analgesic details were collected from the electronic medical records. RESULTS: Fifteen studies (n = 1166; combined mean age 4.93y) met the systematic review criteria. The percentage of patients receiving opioids postoperatively overall ranged from 3.33-100%, and doses ranged from 0.07 to 0.35 mg/kg oMEDD. At the RCH, perioperative opioid use was analyzed from 150 inguinal hernia patients (male - 113, median age - 3 months old). Postoperatively, 26 (17.3%) patients received opioids. The most commonly administered opioids were fentanyl (0.04-0.60 mg/kg oMEDD) in the post anaesthesia care unit and oxycodone (0.14-0.40 mg/kg oMEDD) in the first 24 h postoperatively. Older age at surgery, female sex and absence of regional anaesthesia were significantly associated with higher risk of total opioid use. No patients received an opioid prescription at discharge. CONCLUSION: There is demonstratable variability in opioid prescribing practices for paediatric inguinal hernia patients as described in the literature. At our institution opioids were not used frequently in postoperative period.

BACKGROUND: Hirschsprung disease is commonly encountered by pediatric surgeons. Despite advances in the surgical management, these children may experience symptoms of bowel dysfunction throughout adulthood. Anorectal manometry may be used to assess post-operative anorectal structure and function. This review aimed to consolidate and evaluate the literature pertaining to post-operative findings of anorectal manometry in children with Hirschsprung disease. PURPOSE: (1) Synthesize the available data regarding anorectal motility patterns in children following repair of Hirschsprung disease. (2) Evaluate the reported anorectal manometry protocols. DATA SOURCES: We performed a systematic review of four databases: Embase, MEDLINE, the Cochrane Library, and PubMed. STUDY SELECTION: This systematic review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Studies reporting results of post-operative anorectal manometry in children with Hirschsprung disease were evaluated for inclusion. RESULTS: Twenty-three studies satisfied inclusion criteria, with a combined cohort of 939 patients. Post-operative anorectal manometry results were reported for 682 children. The majority of included studies were assessed as "poor quality." Disparate manometry protocols, heterogeneous cohorts, and lack of standardized outcome assessments introduced a risk of outcome reporting bias, limited the comparability of results, and impeded clinical translation of findings. CONCLUSIONS: This systematic review demonstrated the lack of high-quality evidence underlying the current understanding of post-operative anorectal motility in children with HD. There was little consistency in reported manometry outcomes between studies. In future work, emphasis must be placed on the application of standardized manometry protocols, cohort reporting, and patient outcome assessments.

BACKGROUND: A significant proportion of children experience bowel dysfunction (including constipation and fecal incontinence) following surgical repair of Hirschsprung disease (HD). Persistent symptoms are thought to relate to underlying colonic and/or anorectal dysmotility. Manometry may be used to investigate the gastrointestinal motility patterns of this population. PURPOSE: To (1) evaluate the colonic manometry equipment and protocols used in the assessment of the post-operative HD population and (2) summarize the available evidence regarding colonic motility patterns in children with HD following surgical repair. DATA SOURCES: We performed a systematic review of the Cochrane Library, Embase, MEDLINE, and PubMed databases (January 1, 1980 and March 9, 2020). Data were extracted independently by two authors. STUDY SELECTION: This systematic review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Studies reporting the post-operative assessment of children with HD using colonic manometry were considered for inclusion. RESULTS: Five studies satisfied selection criteria, providing a combined total of 496 children. Of these, 184 children with repaired HD underwent colonic manometry. Studies assessed heterogeneous populations, utilized variable manometry equipment and protocols, and reported limited baseline symptom characteristics, thus restricting comparability. All studies used low-resolution colonic manometry. CONCLUSIONS: This systematic review highlighted the paucity of evidence informing the understanding of colonic dysmotility in the post-operative HD cohort. Current literature is limited by variable methodologies, heterogeneous cohorts, and the lack of high-resolution manometry.

OBJECTIVE: To investigate the quality of life (QoL) impact on primary caregivers of children with esophageal atresia. STUDY DESIGN: We used a prospective cohort study design, inviting primary caregivers of children with esophageal atresia to complete the following questionnaires: Parent Experience of Child Illness (PECI), Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety, PROMIS Depression, 12-Item Short Form Survey (SF-12), and Pediatric Quality of Life Inventory (PedsQL). The PECI, PROMIS Anxiety and Depression, and SF-12 assessed caregiver QoL, and the PedsQL assessed patient QoL. Patients with Gross type E esophageal atresia served as controls. RESULTS: The primary caregivers of 100 patients (64 males, 36 females; median age, 4.6 years; range, 3.5 months to 19.0 years) completed questionnaires. The majority (76 of 100) of patients had Gross type C esophageal atresia. A VACTERL (vertebral anomalies, anorectal malformation, cardiac anomalies, tracheoesophageal fistula, renal anomalies, limb anomalies) association was found in 30, ≥1 esophageal dilatation was performed in 57, and fundoplication was performed in 11/100. When stratified by esophageal atresia types, significant differences were found in 2 PECI subscales (unresolved sorrow/anger, P = .02; uncertainty, P = .02), in PROMIS Anxiety (P = .02), and in SF-12 mental health (P = .02) and mental component summary scores (P = .02). No significant differences were found for VACTERL association, nor esophageal dilatation. Requirement for fundoplication resulted in lower SF-12 general health score, and lower PedsQL social and physical functioning scores. CONCLUSIONS: We have demonstrated that caring for a child with esophageal atresia and a previous requirement for fundoplication impacts caregiver QoL.

AIM: Enuresis, defined as intermittent incontinence occurring exclusively during sleep, affects 4-19% of children, but can be effectively treated using education and alarm-bell therapies. However, delays in treatment are likely to impact upon the quality of life of the child, parents and carers. Poor quality and incomplete referrals are thought to be a major driver of inefficiencies. The aim of this study was to explore characteristics of enuresis referrals on the waiting list for a general medicine clinic at a tertiary paediatric hospital. METHODS: An audit was conducted to examine all enuresis referrals on the general medicine outpatient clinic waiting list in February 2019 at The Royal Children's Hospital, Melbourne. Enuresis referrals with an organic cause and those for children less than 5 years of age were excluded. RESULTS: Of the 2613 referrals on the general medicine waiting list, 486 of 2613 (19%) were related to enuresis. The median age of patients on the waiting list was 8 years and 65% (315/486) were male. Sufficient detail was provided to determine temporal and disease stratification in 45% (218/486) of referrals; primary versus secondary enuresis, and monosymptomatic versus non-monosymptomatic enuresis. The mean number of days on the waiting list calculated at the time of data extraction (13 February 2019) was 226 (±179) days. CONCLUSIONS: The findings from this study suggest that there are long waiting times for enuresis services and referrals often do not contain complete information.
