    BACKGROUND: Successful implementation of environmentally sustainable practices in the operating theatre (OT) requires stakeholder engagement. We evaluate the knowledge, attitudes, and practices of OT users in our institution towards sustainable practices in the OT.

    METHODS: A survey was conducted among OT users in August 2022. Respondents completed a 44-question anonymised online survey covering sustainability in (1) knowledge, (2) attitude, (3) practice, and (4) proposed changes to current practices. Points were assigned to knowledge (15 points) and attitude (40 points) sections. Practice was evaluated based on proportion of measures practiced. Appropriate statistical tests were used, with significance p

    PURPOSE: The COVID-19 pandemic has placed extraordinary demands on healthcare services worldwide. Some have reported increased viral transmission to healthcare workers during aerosol-generating procedures such as intubation. We report our experience with universal preoperative and preprocedural screening for COVID-19 in children requiring general anaesthesia with low risk of having the infection.

    METHODS: This was a data review involving children aged

    INTRODUCTION: The Coronavirus Disease 2019 (COVID-19) has dramatically affected global healthcare systems. We aimed to determine the response of our paediatric surgical fraternity to a disease that overwhelmingly affects adults.

    MATERIALS AND METHODS: We conducted a cross-sectional questionnaire-based study over 6 weeks during a federally mandated lockdown. Using snowball sampling, we recruited paediatric surgeons, trainees and medical officers from paediatric surgical units in Malaysia. The anonymous online questionnaire covered sociodemographic information, changes in patient care, redeployment, concerns regarding family members, and impact on training. Mental well-being was assessed using the Depression, Anxiety and Stress Scale (DASS-21). Kruskal-Wallis, ANOVA and multiple regression analysis was used, with significance level 0.05.

    RESULTS: Of the 129 eligible participants, 100(77%) responded. Junior doctors had clinically higher levels of depression, anxiety, and stress. Age <30 years was significantly associated with anxiety. Junior doctors believed that redeployment led to loss of surgical skills (p<0.001) and trainees felt that clinical application of knowledge had reduced (p<0.020).

    CONCLUSION: Specific to our paediatric surgical community, this study highlights areas of concern, particularly among junior doctors. It is likely that recurrent cycles of the pandemic will occur soon. These issues must be addressed to preserve the mental and emotional well-being of all health care workers.

    BACKGROUND:  Laparoscopic hernia repair (LH) is reported to have superior outcomes in pediatric inguinal hernia repair, but its advantages in incarcerated inguinal hernia (IIH) are not defined. We compare the outcomes of LH versus open hernia repair (OH) for pediatric IIH.

    METHODS:  We performed a systematic review on all published analyses of LH versus OH for IIH. We identified studies published in 2000 to 2018 from Medline, PubMed, Embase, Google Scholar, and Cochrane databases. We included only studies that compared both surgical techniques on children aged 18 years or younger. Search terms were variations of "incarcerated inguinal hernia," "hernia repair," "laparoscopy," and "child." We categorized complications as major (testicular atrophy, ascending testis, recurrence, iatrogenic visceral injury) and minor (wound infection). Heterogeneity was assessed using I2; meta-analyses were performed using random- or fixed-effects models as appropriate. Weighted mean differences (WMDs) or odds ratios (ORs), with their corresponding 95% confidence intervals (CIs), were used for analysis of continuous and dichotomous variables, respectively. Significance level was at p-value less than 0.05.

    RESULTS:  Our initial search yielded 549 unique citations. Eight retrospective cohort (RC) studies (584 patients) were included in the final analysis (339 LH, 245 OH). Overall, major complications (eight RC; n = 584; OR = 0.38; 95% CI: 0.17-0.88; p = 0.02) were more common in OH. When each complication was assessed individually, there were no differences between groups. The length of hospital stay in the LH group was shorter than in the OH group (five RC; n = 418; WMD = - 1.39; 95% CI, -2.56 to -0.22; p = 0.02).

    CONCLUSION:  Laparoscopic repair for IIH is associated with less major complications and shorter hospital stay, but data are limited due to the absence of randomized controlled trials.

    BACKGROUND: A shortage of specialist paediatric surgeons in Malaysia led to establishment of a national postgraduate training programme in 2004. We aimed to identify sociodemographic factors impacting training experience, and to define pressure points during training to inform targeted trainee support strategies.

    METHODS: We conducted an anonymized online survey in June 2021 on all programme graduates. Participants were asked for sociodemographic data, both current and during training. Likert scale responses were required for questions regarding adequacy of support received for family, health and personal issues during training. A free text response question soliciting suggestions for programme improvement was included. Data are reported as median (range). Chi-square/Fisher's exact tests for categorical variables and Mann-Whitney U tests for continuous variables were used, with p<0.05 significance.

    RESULTS: Of 53 eligible participants, 52 (98%) responded, 24 (46%) were female. Marital status was similar between genders at entry, but female trainees were more likely to be unmarried on exit (p = 0.001), and less likely to have children while training (p = 0.017). Of the 6 female and 18 male trainees who had children while training, women were more likely to take parental leave (p = 0.01). The majority felt advice given regarding parental leave and managing training while having children were poor. In thematic analysis of free text answers, lack of hands-on experience was the most common concern.

    CONCLUSION: Factors related to marriage and parenthood significantly associate with gender amongst trainees in Malaysia despite both genders being well represented. Concerns regarding adequacy of hands-on training highlight the need for educational innovations such as simulation models.

    LEVEL OF STUDY: Level III.

    PURPOSE: The COVID-19 pandemic has placed an unprecedented test on the delivery and management of healthcare services globally. This study describes the adaptive measures taken and evolving roles of the members of the paediatric surgery division in a developing country during this period.

    METHODS: We adopted multiple adaptive strategies including changes to stratification of surgeries, out-patient services by urgency and hospital alert status, policy writing involving multidisciplinary teams, and redeployment of manpower. Modifications were made to teaching activities and skills training to observe social distancing and mitigate reduced operative learning opportunities. Roles of academic staff were expanded to include non-surgical duties.

    RESULTS: The planned strategies and changes to pre COVID-19 practices were successful in ensuring minimal disruption to the delivery of essential paediatric surgical services and training. Despite the lack of established guidelines and literature outlining strategies to address the impact of this pandemic on surgical services, most of the initial measures employed were consistent with that of other surgical centres.

    CONCLUSION: Changes to delivery of surgical services and surgical training warrant a holistic approach and a constant re-evaluation of practices with emergence of new experiences and guidelines.

    Necrotizing enterocolitis has a wide clinical spectrum of manifestation. We report a novel method of managing focal isolated perforation in necrotizing enterocolitis by using diagnostic laparoscopy to localize the site of perforation and by making a microincision over the perforation to perform exteriorization or limited resection and primary anastomosis.

    Studies show that conservative management in acute uncomplicated appendicitis (AUA) is an alternative to surgery. This study aims to determine factors affecting parental preference in management of AUA and their decision for research participation. We conducted surveys on parents whose children were admitted with suspicion of appendicitis but later confirmed not to have appendicitis. Information on appendicectomy versus conservative treatment with antibiotics was provided using a fixed script and standard information leaflet. Questionnaires covered factors influencing decisions, opinions regarding research, treatment preference and demographic data. We excluded parents not fluent in English. Of 113 respondents, 71(62.8%) chose antibiotics, 39(34.5%) chose appendicectomy, and 3(2.7%) had no preference. Reasons given for choosing antibiotics were fear of surgical risks and preferring less invasive treatment. Those choosing appendicectomy expressed preference for definitive treatment and fear of recurrence. Majority were against randomisation (n = 89, 78.8%) and blinding (n = 90, 79.7%). Over half found difficulty involving their child in research (n = 65, 57.5%). Most thought that research is important (66.4%) and beneficial to others (59.3%). Parents who perceived their child as healthy found research riskier (p = 0.039). Educated parents were more likely to find research beneficial to others (p = 0.012) but less accepting of randomisation (p = 0.001).Conclusion: More parents appear to prefer conservative treatment for acute uncomplicated appendicitis. Researchers must consider parental concerns regarding randomisation and blinding.What is Known:• Conservative management of acute uncomplicated appendicitis in paediatric patients is safe and effective, sparing the child the need for an operation; however, neither conservative nor surgical management is proven to be superior.• Randomised controlled trials provide the highest level of evidence, but it is challenging to recruit paediatric patients as participants in such clinical trials.What is New:• More parents prefer conservative management of uncomplicated appendicitis over surgical management for their children due to fear of surgical risks and complications• Randomisation in trial design is significantly associated with a parent's decision to reject their child's participation in a clinical trial.

    PURPOSE: To explore the experiences and needs of parents while waiting for their children undergoing surgery.

    DESIGNS AND METHODS: A descriptive qualitative study was conducted. A purposive sample of 11 parents who went through their first waiting experiences during their children's surgeries in a Singapore public hospital was recruited. Children younger than or equal to 16 years of age were included. A semi-structured interview guide facilitated the individual face-to-face interviews. Thematic analysis was used.

    RESULTS: Four themes were identified: "Care and care provision affecting waiting experiences", "Parental concerns and surgery affecting waiting experiences", "Coping strategies used during waiting periods" and "Recommendations to improve waiting experiences". Pre-operative instructions, the professionalism of medical teams, and a lack of timely updates affected parental experiences. Parents expressed their worries. The complexities and types of surgery influenced how they felt. Their concerns included potential complications, surgical outcomes, anesthesia-related side effects, and post-operative care including pain. They spent their waiting times eating, resting, using their smart devices, and coping with a support system. Environmental improvements, more updates, and mobile applications were recommended by the participants.

    CONCLUSION: For a parent, the wait during his/her child's surgery can be unsettling. Our results give insights into parental waiting experiences and needs during their children's surgeries.

    PRACTICE IMPLICATIONS: These findings can guide the improvement of the current practise based on our evidence or the implementation of newer technology to provide better waiting experiences for parents during their children's surgeries and to enhance the quality of clients' experiences in the hospital.

    PURPOSE: Little is known of how children seek health information. This study evaluates online health information (OHI) seeking behaviours in adolescents undergoing major elective surgical procedures and compares responses within parent-child dyads.

    METHODS: With institutional approval, we prospectively surveyed parents of children admitted to our institution for major elective operations between November 2017 and November 2018, using convenience sampling. Patients aged 12 years and above were also invited. Each respondent completed an anonymized modification of a previously published survey on Internet usage. Chi squared tests were used for categorical data, with significance at P value

    BACKGROUND: Umbilical granuloma is a common infantile condition which usually responds to non operative management. Copper sulphate (CuSO4) is often used as chemical cauterization but can cause superficial skin burns. An alternative is table salt (NaCl), which osmotically dehydrates wet granulation tissue causing necrosis. We aimed to compare the effectiveness of NaCl versus CuSO4 in treating umbilical granuloma.

    METHOD: We performed a multi centerrandomized controlled trial involving three regional pediatricsurgical units. We included children who presented with umbilical granuloma from December 2018 to May 2020. Children who received treatment prior to index visit were excluded. They were randomly allocated to receive NaCl (twice/day application for 5 days by caregiver) or CuSO4 (single application by clinician). Demographic data, compliance in the NaCl group by pill counting method, treatment outcomes, and complications were recorded. Treatment success was defined as complete lesion resolution. Partial or no response was considered treatment failure. Subsequent treatment then reverted to the respective center's routine management.

    RESULT: We recruited 70 participants with 6 dropouts (2 defaulters, 1 vitellointestinal duct, 3 urachal remnants), leaving 64 subjects for final analysis: 31 NaCl, 33 CuSO4. Compliance rate of 77.4% was recorded for NaCl, with 6 (20%) 'poor compliance' participants stopping therapy before completion owing to complete resolution. NaCl group had a significantly higher complete resolution rate (90.4%) compared to CuSO4 (69.7%), p = 0.040. No NaCl participant developed complications versus 9% (n = 3) in CuSO4 (periumbilical superficial skin burn).

    CONCLUSION: Table salt is an ideal treatment choice for umbilical granuloma as it is effective, safe, and readily available.

    BACKGROUND: Increased intra-abdominal pressure (IAP) is seen in patients after congenital diaphragmatic hernia (CDH) repair owing to reduction of thoracic contents into the relatively smaller abdominal cavity. In infants, IAP ≥11 mmHg is considered intra-abdominal hypertension (IAH). We aim to determine the incidence of IAH and its relationship with duration of ventilatory support, and gastrointestinal function post CDH repair.

    METHODS: We prospectively recruited all neonates who had CDH repair in four hospitals in Malaysia from June 2018 to October 2020. Intra vesical pressure was used as a proxy for IAP and was measured for 5 consecutive days post surgery. The daily median value was used for analysis. We categorized IAP as <11 mmHg (no IAH), 11-15 mmHg (IAH), and >15 mmHg (severe IAH). Incidence of IAH, its effects on the duration of ventilatory support, and gastrointestinal function were studied.

    RESULTS: There were 24 neonates included in this study. They were operated between day 1 and 6 of life (median: 4 days old). IAH was detected within the first 3 days post surgery, with 83% occurring on day one. Those requiring ventilatory support for more than 3 days contributed the largest proportion of IAH (n = 17, 71%). There was strong correlation between days of IAH and duration of ventilation (p

    INTRODUCTION: Anorectal manometry may be useful to objectively evaluate anorectal function following definitive pullthrough for Hirschsprung Disease (HD) but there is little published data. Our study aims to investigate anorectal manometry findings and their association with bowel function.

    METHODOLOGY: This was a prospective observational study. Convenience sampling method was used to recruit all HD patients who had definitive pullthrough from January 2019 to December2020 in our institution. High-resolution anorectal manometry (HRAM) was used to record anal resting pressure (ARP), length of high-pressure zone (HPZ), and presence/absence of recto-anal inhibitory reflex (RAIR). The Paediatric Incontinence/Constipation Scoring System (PICSS) was scored for all participants. PICSS is a validated questionnaire with scores mapped to an age-specific normogram to denote constipation, incontinence, and their combinations. Non-parametric and chi-square tests at significance p<0.05 were conducted to examine the relationship between PICSS categories and manometry findings. Ethical approval was obtained.

    RESULTS: There were 32 participants (30 boys). Median age at participation was 26.5 months (range: 13.8-156). Twenty-four (75%) had transanal pullthrough, 8(25%) underwent Duhamel procedure. PICSS scored 10(31.3%) as normal, 8(25%) as constipation, 10(31.3%) as incontinent, and 4(12.5%) as mixed. RAIR was present in 12 patients (37.5%). HPZ, maximum ARP, mean ARP were comparable across all PICSS groups without statistically significant differences. Presence of RAIR was not significantly associated with any PICSS groups (p = 0.13).

    CONCLUSION: Bowel function does not appear to be significantly associated with HRAM findings after definitive pullthrough for HD, but our study is limited by small sample size. RAIR was present in 37.5% patients after pullthrough.

    LEVEL OF EVIDENCE: Level II.

    INTRODUCTION: Doppler scrotal ultrasonography (US) is the modality of choice in diagnosing testicular torsion. We aimed to evaluate the performance of scrotal US in diagnosing testicular torsion over the past 18 years in our institution and determine the factors contributing to the length of wait times for it.

    METHODS: A retrospective review was conducted of boys who presented with acute scrotal pain from 2014 to 2015. US reports, operative findings, final diagnosis and key time points of the patients' journey (time to emergency department consultation, time to admission, time to US and time to operating theatre [OT]) were collected. US performance results were compared with those observed in a historical cohort from 1998 to 2004. Wait times were compared between operated and non-operated patients.

    RESULTS: Data from 519 boys with a mean age of 9.15 years was collected. Of these, 438 (84.4%) boys had undergone initial scrotal US; of these scrotal US cases, 28 were surgically explored, with 23 confirmed to have torsion. Another five cases were explored without prior US, and all were confirmed to have torsion. Performance analysis of US showed a sensitivity of 100% and a specificity of 98.8%. There was no significant difference between wait times of operated and non-operated patients. Time to US (P < 0.0001, r = 0.96) and time to OT (P < 0.0001, r = 0.64) correlated significantly with the total time from presentation to surgery.

    CONCLUSION: There has been an improvement in the diagnostic performance of scrotal US for testicular torsion over the past 18 years. Quality improvement programmes targeted at reducing wait times for patients presenting with acute scrotum should target time to US and time to OT.

    BACKGROUND: Congenital diaphragmatic hernia (CDH) survivors often experience long-term CDH-associated morbidities, including musculoskeletal, gastrointestinal and respiratory issues. This study evaluates parent-reported health-related quality of life (HRQOL) and family impact of the disease.

    METHODS: Electronic medical records (EMR) were reviewed and phone surveys performed with parents of CDH survivors who underwent repair at our institution from 2010 to 2019. They completed the following Pediatric Quality of Life Inventory™ (PedsQL™) questionnaires: Generic Core Scales 4.0 (parent-proxy report) and Family Impact (FI) Module 2.0. Age-matched and gender-matched healthy controls from an existing database were used for comparison. Subgroup analysis of CDH patients alone was also performed. Appropriate statistical analysis was used with p

    OBJECTIVE: Paediatric living donor liver transplantation (LDLT) has gained popularity due to limited deceased donor organ supply. Some studies report inequalities in donor and recipient gender profiles, but data are sparse. We evaluated LDLT donor-recipient gender profiles, comparing country income categories and gender disparity level.

    DESIGN: We performed a systematic review, searching PubMed, Embase and Cochrane databases for publications dated January 2006-September 2021. We included full-text English articles reporting gender in ≥40 universally sampled donor-recipient pairs. Search terms were permutations of 'liver transplant', 'living donor' and 'paediatric'. Countries were grouped as high/middle/low-income economies based on World Bank criteria and into groups based on deviation from gender parity in Gender Development Index (GDI) values (group 1 indicating closest to gender parity, group 5 indicating furthest). Proportions analysis with corresponding 95% CI were used for analysis of dichotomous variables, with significance when 95% CI did not cross 0.5. Data are reported as female proportion (%) and 95% CI.

    RESULTS: Of 12 525 studies identified, 14 retrospective studies (12 countries; 6152 recipients and 6138 donors) fulfilled study inclusion criteria. Male recipient preponderance was seen in lower middle-income countries (all were also GDI group 5) (39.3 (95% CI 34.7 to 44.0)) and female recipient preponderance in GDI groups 1 and 3. Female donor preponderance was seen overall (57.4% (95% CI 55.1 to 59.6)), in middle income countries and in three of four GDI groups represented.

    CONCLUSION: There are significant imbalances in recipient-donor gender profiles in paediatric LDLT that are not well explained. The reasons for overall female donor preponderance across income tiers must be scrutinised.

    PURPOSE: Down syndrome (DS) is a common abnormality associated with anorectal malformation (ARM) and Hirschsprung's disease (HD). However, quality of life (QOL) in ARM and HD patients with DS is under-researched. This study compares parent-reported QOL and bowel function in ARM and HD patients with DS to those without.

    METHODS: Between December 2020 to February 2023, parents of ARM and HD patients with and without DS aged 3-17 years who had undergone surgery > 12 months prior at four tertiary referral centers were recruited. We used the Pediatric Quality of Life Inventory™ (PedsQL™) Generic Core Scales, General Well-Being (GWB) Scale and Family Impact (FI) Module questionnaires, and the Rintala bowel function score (BFS).

    RESULTS: There were 101 ARM, 9 (8.9%) of whom had DS; and 87 HD, of whom 6 (6.9%) had DS. Parent-reported Core scores in ARM and HD with DS were comparable to those without DS. However, ARM and HD with DS had worse scores in the FI Module and bowel function than those without DS.

    CONCLUSION: Although parent-reported QOL in ARM and HD with DS is similar to those without DS, family impact and BFS are worse. Our findings are limited by small sample size in proportion of DS patients.
