    BACKGROUND: Quality of life (QOL) is an important clinical endpoint in paediatric chronic conditions. How parent-proxy reports differ from child self-reported QOL in patients with anorectal malformation (ARM) and Hirschsprung's disease (HD) has not been well examined to date. This study evaluates agreement between parent-proxy and child-reported QOL scores in ARM and HD patients compared to healthy controls.

    METHODS: We recruited ARM and HD patients aged 5-17 years and their parents at four tertiary referral centres between December 2020 to February 2023 who had corrective surgery done >12 months prior. Healthy controls were age-matched and gender-matched. They completed the Pediatric Quality of Life Inventory™ (PedsQL™) Generic Core Scales and General Well-Being (GWB) Scale. The questionnaires were administered in parallel parent-proxy-report and child self-report formats. Appropriate statistical analysis was performed with p

    PURPOSE: Pediatric solid tumors require coordinated multidisciplinary specialist care. However, expertise and resources to conduct multidisciplinary tumor boards (MDTBs) are lacking in low- and middle-income countries (LMICs). We aimed to profile the landscape of pediatric solid tumor care and practices and perceptions on MDTBs among pediatric solid tumor units (PSTUs) in Southeast Asian LMICs.

    METHODS: Using online surveys, availability of specialty manpower and MDTBs among PSTUs was first determined. From the subset of PSTUs with MDTBs, one pediatric surgeon and one pediatric oncologist from each center were queried using 5-point Likert scale questions adapted from published questionnaires.

    RESULTS: In 37 (80.4%) of 46 identified PSTUs, availability of pediatric-trained specialists was as follows: oncologists, 94.6%; surgeons, 91.9%; radiologists, 54.1%; pathologists, 40.5%; radiation oncologists, 29.7%; nuclear medicine physicians, 13.5%; and nurses, 81.1%. Availability of pediatric-trained surgeons, radiologists, and pathologists was significantly associated with the existence of MDTBs (P = .037, .005, and .022, respectively). Among 43 (89.6%) of 48 respondents from 24 PSTUs with MDTBs, 90.5% of oncologists reported > 50% oncology-dedicated workload versus 22.7% of surgeons. Views on benefits and barriers did not significantly differ between oncologists and surgeons. The majority agreed that MDTBs helped to improve accuracy of treatment recommendations and team competence. Complex cases, insufficient radiology and pathology preparation, and need for supplementary investigations were the top barriers.

    CONCLUSION: This first known profile of pediatric solid tumor care in Southeast Asia found that availability of pediatric-trained subspecialists was a significant prerequisite for pediatric MDTBs in this region. Most PSTUs lacked pediatric-trained pathologists and radiologists. Correspondingly, gaps in radiographic and pathologic diagnoses were the most common limitations for MDTBs. Greater emphasis on holistic multidisciplinary subspecialty development is needed to advance pediatric solid tumor care in Southeast Asia.

    BACKGROUND: Hospital admissions and surgical operations commonly trigger anxiety in young children. Despite employing numerous support measures in our hospital, such as a pre-operative play room, the encouragement of parental companionship during induction of anaesthesia and distraction therapy, allaying the anxiety of our young surgical patients remains a challenge.

    OBJECTIVES: To evaluate the effectiveness of a Home-Initiated-Programme-to-Prepare-for-Operation (HIPPO) on emotional manifestation and anxiety in children undergoing surgery.

    DESIGN, SETTING AND PATIENTS: One hundred and thirty children were randomly assigned to either control or intervention group between February 2018 and April 2019 in a tertiary paediatric hospital in Singapore.

    INTERVENTION: In addition to our standard pre-operative workflow, the intervention group received an additional home preparation kit consisting of an animated video on preoperative preparation and age-specific preoperative preparation activity sheets.

    MAIN OUTCOME MEASURES: The primary outcome was the Children's Emotional Manifestation Scale score to evaluate behaviour and emotion in the children before and during induction of anaesthesia. Secondary outcomes evaluated anxiety levels in parents and children, the child's behaviour and degree of co-operation using the State-Trait Anxiety Inventory scores, State-Trait Anxiety Inventory Children scores, the Induction Compliance Checklist scores, the Visual Analogue Scale scores for anxiety and the feedback questionnaire.

    RESULTS: The difference between the Children's Emotional Manifestation Scale score in control and intervention groups was not statistically significant. A promising difference was however observed in one of the secondary outcomes where the state-State-Trait Anxiety Inventory Children scores of 7 to 10-year olds in the intervention group almost reached significance; P = 0.067.

    CONCLUSION: Despite being a child-friendly, easily accessible and affordable tool for patient education, HIPPO did not reduce anxiety experienced by children in the pre-operative waiting area or during induction of anaesthesia.

    Hirschsprung's Disease (HD) is a congenital disorder causing severe constipation in infants and children. Suction rectal biopsy (SRB) is the preferred technique for obtaining tissue samples for histopathological evaluation. In low-resource settings like Malaysia, cost-effective diagnostic approaches are necessary, making single sample SRB valuable. This study evaluates the diagnostic accuracy and sufficiency of a single macroscopically adequate sample in suction rectal biopsies for the histopathological confirmation of HD. We conducted a retrospective study of children who underwent suction rectal biopsies for the diagnosis of HD at Hospital Raja Perempuan Zainab II (HRPZII), Kota Bharu, Kelantan. A total of 68 patients were included in the study. The inadequacy rate for bedside SRB was 14%, comparable to current literature. Our study found no statistically significant association between sample inadequacy and gestational age, gender, birth weight, or weight at biopsy. Complication rates were 0%, consistent with literature reports. Calretinin staining, an additional technique, was performed in 23 biopsy episodes, with a 4.3% inadequacy rate, compared to 20% in specimens not subjected to calretinin staining. The cost of SRB almost doubled with each additional sample taken, significant in low-resource environments. In conclusion, single sample SRBs can be adequately diagnostic and cost-effective in low-resource settings, providing valuable insights for healthcare facilities in Malaysia and other developing countries. The use of adjunctive techniques such as calretinin staining may improve diagnostic accuracy while maintaining cost-effectiveness. Further prospective studies with larger sample sizes are needed to validate these findings.

    BACKGROUND: Assessment of postoperative bowel function in anorectal malformation (ARM) patients is crucial for benchmarking outcomes. We compared existing bowel function scoring systems in various aspects in patients with ARM.

    METHODS: With ethical approval, this was a cross-sectional study involving 5 paediatric surgery referral centres in Malaysia, comparing the Kelly, Japanese Study Group of Anorectal Anomalies (JSGA), Holschneider and Krickenbeck bowel function questionnaires. We recruited patients aged 4-17 years, who had completed definitive surgery & stoma closure (where relevant) > 12 months prior to participation. We standardised outcomes of each scoring system into categories ('good', 'fair', 'poor' and 'very poor') to facilitate comparison. Parents & patients were surveyed and asked to rate the ease of understanding of each questionnaire. The difference in protocol scores rated between parents and patients were compared. Association of each bowel function scoring protocol with type of anomaly was assessed. Statistical significance was p

    PURPOSE: Patients with anorectal malformation (ARM) and Hirschsprung's disease (HD) live with long-term impact of these diseases even into adulthood. We aimed to explore the physical, social and emotional impact of these diseases in adolescents and young adults to develop best practices for transition care.

    METHODS: We conducted one-on-one in-depth interviews with ARM and HD patients aged  ≥ 11 years who had undergone surgery at four tertiary referral centers. All interviews were audio-recorded and transcribed verbatim. We analyzed transcripts for recurring themes, and data were collected until data saturation was reached. Three researchers independently coded the transcripts for major themes using thematic analysis approach.

    RESULTS: We interviewed 16 participants (11 males) between October 2022 and April 2023. Ages ranged from 11 to 26 years. Five major themes emerged: (1) personal impact (subthemes: physical, emotional and mental health, social, school), (2) impact on family, (3) perceptions of their future (subthemes: relationships, career, state of health), (4) sources of support (subthemes: family, peers, partner), and (5) transition care (subthemes: concerns, expectations). Only females expressed concerns regarding future fertility.

    CONCLUSION: This study highlights the evolving problems faced by adolescents and young adults with ARM and HD, especially gender-specific concerns. Our findings can inform efforts to provide individualized care.

    PURPOSE: Early diagnosis of biliary atresia (BA) is critical for best outcomes, but is challenged by overlapping clinical manifestations with other causes of obstructive jaundice in neonates. We evaluate the performance of the modified Simple BA Scoring System (SBASS) in diagnosing BA.

    METHODS: We performed a prospective, cross-sectional study on infants with cholestatic jaundice (June 2021-December 2022). Modified SBASS scoring was applied and compared to the eventual diagnosis (as per intraoperative cholangiogram (IOC) and liver histopathology). The score (0-6), consists of gall bladder length  0.7(+ 2), gamma-glutamyl transferase (GGT) ≥ 200 U/L (+ 2).

    RESULTS: 73 were included: Fifty-two (71%) had BA. In the non-BA group, 6 (28%) had percutaneous cholangiography (PTC) while 15 (72%) had intraoperative cholangiogram (IOC). At a cut-off of 3, the modified SBASS showed sensitivity of 96.2%, specificity of 61.9% and overall accuracy of 86.3% in diagnosing BA. Area under receiver operating characteristic curve was 0.901. GGT had the highest sensitivity (94.2%), while triangular cord sign showed the highest specificity at 95.2%.

    CONCLUSION: The SBASS provides a bedside, non-invasive scoring system for exclusion of BA in infantile cholestatic jaundice and reduces the likelihood of negative surgical explorations.

    PURPOSE: Children with anorectal malformation (ARM) and Hirschsprung's disease (HD) often experience bowel symptoms into adulthood, despite definitive surgery. This study evaluates the quality of life (QOL) and bowel functional outcome of children treated for ARM and HD in comparison to healthy controls.

    METHODS: Between December 2020 and February 2023, we recruited patients with ARM and HD aged 3-17 years at four tertiary referral centres, who had primary corrective surgery done >12 months prior. Healthy controls were age-matched and sex-matched. All participants completed the Pediatric Quality of Life Inventory Generic Core Scales 4.0, General Well-Being (GWB) Scale 3.0 and Family Impact (FI) Module 2.0 Questionnaires. Bowel Function Score (BFS) Questionnaires were also administered. We also performed subgroup analysis according to age categories. Appropriate statistical analysis was performed with p<0.05 significance. Ethical approval was obtained.

    RESULTS: There were 306 participants: 101 ARM, 87 HD, 118 controls. Patients with ARM and HD had significantly worse Core and FI Scores compared with controls overall and in all age categories. In the GWB Scale, only ARM and HD adolescents (13-17 years) had worse scores than controls. ARM and HD had significantly worse BFSs compared with controls overall and in all age categories. There was significant positive correlation between BFS and Core Scores, GWB Scores and FI Scores.

    CONCLUSION: Patients with ARM and HD had worse QOL than controls. Lower GWB Scores in adolescents suggests targeted interventions are necessary. Bowel function influences QOL, indicating the need for continuous support into adulthood.

    OBJECTIVE: To develop an international core outcome set (COS), a minimal collection of outcomes that should be measured and reported in all future clinical trials evaluating treatments of acute simple appendicitis in children.

    SUMMARY OF BACKGROUND DATA: A previous systematic review identified 115 outcomes in 60 trials and systematic reviews evaluating treatments for children with appendicitis, suggesting the need for a COS.

    METHODS: The development process consisted of 4 phases: (1) an updated systematic review identifying all previously reported outcomes, (2) a 2-stage international Delphi study in which parents with their children and surgeons rated these outcomes for inclusion in the COS, (3) focus groups with young people to identify missing outcomes, and (4) international expert meetings to ratify the final COS.

    RESULTS: The systematic review identified 129 outcomes which were mapped to 43 unique outcome terms for the Delphi survey. The first-round included 137 parents (8 countries) and 245 surgeons (10 countries), the second-round response rates were 61% and 85% respectively, with 10 outcomes emerging with consensus. After 2 young peoples' focus groups, 2 additional outcomes were added to the final COS (12): mortality, bowel obstruction, intraabdominal abscess, recurrent appendicitis, complicated appendicitis, return to baseline health, readmission, reoperation, unplanned appendectomy, adverse events related to treatment, major and minor complications.

    CONCLUSION: An evidence-informed COS based on international consensus, including patients and parents has been developed. This COS is recommended for all future studies evaluating treatment ofsimple appendicitis in children, to reduce heterogeneity between studies and facilitate data synthesis and evidence-based decision-making.

    INTRODUCTION: Heterogeneity in reported outcomes of infants with oesophageal atresia (OA) with or without tracheo-oesophageal fistula (TOF) prevents effective data pooling. Core outcome sets (COS) have been developed for many conditions to standardise outcome reporting, facilitate meta-analysis and improve the relevance of research for patients and families. Our aim is to develop an internationally-agreed, comprehensive COS for OA-TOF, relevant from birth through to transition and adulthood.

    METHODS AND ANALYSIS: A long list of outcomes will be generated using (1) a systematic review of existing studies on OA-TOF and (2) qualitative research with children (patients), adults (patients) and families involving focus groups, semistructured interviews and self-reported outcome activity packs. A two-phase Delphi survey will then be completed by four key stakeholder groups: (1) patients (paediatric and adult); (2) families; (3) healthcare professionals; and (4) researchers. Phase I will include stakeholders individually rating the importance and relevance of each long-listed outcome using a 9-point Likert scale, with the option to suggest additional outcomes not already included. During phase II, stakeholders will review summarised results from phase I relative to their own initial score and then will be asked to rescore the outcome based on this information. Responses from phase II will be summarised using descriptive statistics and a predefined definition of consensus for inclusion or exclusion of outcomes. Following the Delphi process, stakeholder experts will be invited to review data at a consensus meeting and agree on a COS for OA-TOF.

    ETHICS AND DISSEMINATION: Ethical approval was sought through the Health Research Authority via the Integrated Research Application System, registration no. 297026. However, approval was deemed not to be required, so study sponsorship and oversight were provided by Alder Hey Children's NHS Foundation Trust. The study has been prospectively registered with the COMET Initiative. The study will be published in an open access forum.
