Management of undescended testes (UDT) has evolved over the last decade. While urologic societies in the United States and Europe have established some guidelines for care, management by North American pediatric surgeons remains variable. The aim of this systematic review is to evaluate the published evidence regarding the treatment of (UDT) in children.A comprehensive search strategy and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were utilized to identify, review, and report salient articles. Five principal questions were asked regarding imaging standards, medical treatment, surgical technique, timing of operation, and outcomes. A literature search was performed from 2005 to 2020.A total of 825 articles were identified in the initial search, and 260 were included in the final review.Pre-operative imaging and hormonal therapy are generally not recommended except in specific circumstances. Testicular growth and potential for fertility improves when orchiopexy is performed before one year of age. For a palpable testis, a single incision approach is preferred over a two-incision orchiopexy. Laparoscopic orchiopexy is associated with a slightly lower testicular atrophy rate but a higher rate of long-term testicular retraction. One and two-stage Fowler-Stephens orchiopexy have similar rates of testicular atrophy and retraction. There is a higher relative risk of testicular cancer in UDT which may be lessened by pre-pubertal orchiopexy.

Epidemiologic and genomic investigation of SARS-CoV-2 infections associated with 2 repatriation flights from India to Australia in April 2021 indicated that 4 passengers transmitted SARS-CoV-2 to11 other passengers. Results suggest transmission despite mandatory mask use and predeparture testing. For subsequent flights, predeparture quarantine and expanded predeparture testing were implemented.

Effective shared decision-making in pediatric surgery requires clarity regarding which surgical outcomes are most important to patients and their families, and how they prefer to receive the information. Despite how essential this is for effective risk communication, little is known about the communication needs and preferences of patients and their families in elective pediatric surgery.We administered a mailed and online cross-sectional survey in English and French to 548 families before or after surgery for hernia/hydrocele repair or tonsillectomy/adenoidectomy between July 2019 and February 2021. The survey consisted of 22 questions eliciting most valued patient-reported outcomes (PROs) across 4 domains: health-related quality of life (5), functional status (5), symptoms and symptom burden (5), health behaviours and patient experience (7), as well as overall impressions (3), surgical risks (5), communication preferences (4), and demographic questions (16).The survey was completed by 368 patient families (60 preoperative, 308 postoperative, response rate 67.2%). Most respondents (72%) indicated a significant desire to be informed on all listed PROs alongside surgical complications, and highly valued all functional and quality of life outcomes (92.9%89.8%, respectively). Preoperatively, patient families preferred to receive information in the form of pamphlets and websites, whereas postoperatively they preferred direct communication.Families value functional and quality of life PROs as much as clinical outcomes, and increasingly seek more contemporary (electronic) means of risk communication than we currently offer. This data will inform the development of mobile tools for personalized communication in pediatric surgery.

BACKGROUND A popular paradigm to support surgical education for low- and middle-income countries (LMICs) is partnering with high-income country (HIC) surgeons. These relationships may, however, be asymmetric and fail to optimally address the most pressing curricular needs. We explored the effectiveness of our LMIC-HIC educational partnership. METHODS Through a partnership between a HIC (Canada) and a LMIC (Uganda), three candidate surgeons were commissioned for a custom designed 1-year training experience at our HIC accredited pediatric surgical training centre as part of their overall formal education. The training curriculum was developed in collaboration with the LMIC pediatric surgeon and utilized competency-based medical education principles. A Likert and short-answer survey tool was administered to these trainees upon completion of their training. RESULTS All prescribed milestones as well as specialty certification by examination of the College of Surgeons of East, Central and Southern Africa was achieved by participating fellows, each of whom have begun clinical practice, leadership and teaching roles in their home country. Although several obstacles were identified by fellows, all agreed that the experience boosted their clinical and teaching abilities, and was worth the effort. CONCLUSION This endeavour in global pediatric surgical training represents a significant innovation in surgical education partnerships and would be reproducible across different surgical subspecialties and contexts. Such collaborative efforts represent a feasible upskilling opportunity towards addressing global surgical service capacity. LEVEL OF EVIDENCE V.

Clinical practice should be driven by high-quality research that produces evidence to inform best practices. Generation of such evidence is often challenging, particularly for smaller specialties, such as pediatric surgery, that treat many patients with rare diseases. Multi-institutional collaboration is seen as a major strategy to address these challenges. We have recently created the Canadian Consortium for Research in Pediatric Surgery, a national consortium that includes all major pediatric surgical services across Canada. The mission of the Consortium is to improve pediatric surgical care through high-quality collaborative research. In this article, we describe the rationale and methodology for creation of the Canadian Consortium for Research in Pediatric Surgery, demonstrate its achievements to date, and share a number of foundational concepts that are integral to its success. Our aim is to provide a model for creation of such consortia, ultimately leading to improvements in the quality of clinical research and patient care.

Purpose: We evaluated the impact of a virtual Pediatric Surgery Bootcamp curriculum on resource utilization, learner engagement, knowledge retention, and stakeholder satisfaction. Methods: A virtual curriculum was developed around Pediatric Surgery Milestones. GlobalCastMD delivered pre-recorded and live content over a single 10-hour day with a concluding social hour. Metrics of learner engagement, faculty interaction, knowledge retention, and satisfaction were collected and analyzed during and after the course. Results: Of 56 PS residencies, 31 registered (55.4%; 8/8 Canadian and 23/48 US; p=0.006), including 42 learners overall. The virtual BC budget was $15,500 (USD), 54% of the anticipated in-person course.. Pre- and post-tests were administered, revealing significant knowledge improvement (48.6% [286/589] vs 66.9% [89/133] pConclusions: The virtual bootcamp format reduced overall expenses, interfered less with schedules, achieved more inclusive reach, and facilitated content archiving. Despite these advantages, learners and program directors still favored in-person education.

Background: Fostering the success of surgical trainees from low- and middle-income countries (LMICs) plausibly addresses the existing workforce deficit in a sustainable manner, but it is unclear whether and how these trainees are targeted as strategic learners for educational exchanges. The purpose of this review was to assess the quality and outcomes of existing literature on exchanges of surgical trainees between high-income countries (HICs) and LMICs. Methods: We conducted a systematic review of reported instances of surgical training exchanges between HICs and LMICs. After database searching, 2 independent reviewers evaluated titles, abstracts and manuscripts. Selected studies were critically appraised with the use the Critical Assessment Skills Programme Qualitative Checklist and analyzed for trainee level, institutions, countries and subspecialties, as well as reported outcomes of the exchange. Results: Twenty-eight reports met the inclusion criteria and were analyzed. Most publications (18 [64%]) detailed North-to-South exchanges; 1 exchange was bidirectional. General surgery was the most common discipline identified, with 9 other subspecialties described involving learners at all phases of training. Reports were generally of good quality, although outcomes were reported variably, and most authors failed to acknowledge the ethical implications of their study. Conclusion: The articles identified described a variety of surgical exchanges across disciplines, learner types and host/home countries. Few of the exchanges prioritized the learning of surgical trainees from LMICs. There is an increasing need to formalize these exchanges via clear goals and objectives, as well as to prioritize the proper matching of educational goals with local clinical needs.

CONTEXT Despite frequency of gastrostomy placement procedures in children, there remains considerable variability in preoperative work-up and procedural technique of gastrostomy placement and a paucity of literature regarding patient-centric outcomes. OBJECTIVES This review summarizes existing literature and provides consensus-driven guidelines for patients throughout the enteral access decision-making process. DATA SOURCES PubMed, Google Scholar, Medline, and Scopus. STUDY SELECTION Included studies were identified through a combination of the search terms “gastrostomy,” “g-tube,” and “tube feeding” in children. DATA EXTRACTION Relevant data, level of evidence, and risk of bias were extracted from included articles to guide formulation of consensus summaries of the evidence. Meta-analysis was conducted when data afforded a quantitative analysis. EVIDENCE REVIEW Four themes were explored: preoperative nasogastric feeding tube trials, decision-making surrounding enteral access, the role of preoperative imaging, and gastrostomy insertion techniques. Guidelines were generated after evidence review with multidisciplinary stakeholder involvement adhering to GRADE methodology. RESULTS Nearly 900 publications were reviewed, with 58 influencing final recommendations. In total, 17 recommendations are provided, including: (1) tTrial of home nasogastric feeding is safe and should be strongly considered before gastrostomy placement, especially for patients who are likely to learn to eat by mouth; (2) rRoutine contrast studies are not indicated before gastrostomy placement; and (3) lLaparoscopic placement is associated with the best safety profile. LIMITATIONS Recommendations were generated almost exclusively from observational studies and expert opinion, with few studies describing direct comparisons between GT placement and prolonged nasogastric feeding tube trial. CONCLUSIONS Additional patient- and family-centric evidence is needed to understand critical aspects of decision-making surrounding surgically placed enteral access devices for children.

In low- and lower middle-income countries (LMICs), timely access to primary care following thermal injury is challenging. Children with deep burns often fail to receive specialized burn care until months or years post-injury, thus suffering impairments from hypertrophic scarring or joint and soft tissue contractures. We aimed to examine the correlation between limited access to care following burn injury and long-term disability in children in LMICs and to identify specific factors affecting the occurrence of late burn complications. A systematic literature search was conducted to retrieve articles on pediatric burns in LMICs using Medline, Embase, the Cochrane Library, LILACS, Global Health, African Index Medicus, and others. Articles were assessed by two reviewers and reported in accordance with PRISMA guidelines. Of 2896 articles initially identified, 103 underwent full-text review and 14 met inclusion criteria. A total of 991 children who developed long-term burn sequelae were included. Time from injury to consultation ranged from a few months to 17 years. Factors associated with late complications included total body surface area burned, burn depth, low socio-economic status, limited infrastructure, perceived inability to pay, lack of awareness of surgical treatment, low level of maternal education, and time elapsed between burn injury and reconstructive surgery.

Purpose Fellows in Pediatric Surgery need to learn to manage a variety of gynecologic conditions. We completed a needs assessment of Pediatric Surgery training programs to inform development of a standardized gynecology curriculum. Methods A survey was sent to Program Directors of Canadian Pediatric Surgery training programs with 27 questions that focused on the fellowship program, surgical practice, and trainee exposure to pediatric gynecology, and how the envision a standardized gynecology curriculum. Results Six of eight Program Directors responded. All respondents had treated ovarian-related conditions and genital injuries in the past 5 years, and most felt trainees received adequate training in managing these conditions. Most respondents felt trainees had minimal or inadequate training in imperforate hymens, Mullerian anomalies, vulvar abscesses, vaginal foreign bodies, and labial adhesions. Program Directors currently allot an average of 3.5 h to delivering the gynecology objectives. All Program Directors expressed interest in a formal gynecology curriculum delivered through some combination of case-based teaching and/or simulation. Conclusion There is a need for a standardized gynecology curriculum for Pediatric Surgery trainees. Most Pediatric Surgeons will manage gynecological conditions as part of their practice and current Program Directors feel that training is inadequate for a number of gynecological conditions.

Purpose The purpose of this study was to evaluate the management of thyroid nodules in children and assess clinical practice variation (CPV) using the 2015 American Thyroid Association (ATA) guidelines as a standard. Methods Pediatric patients presenting to a tertiary care pediatric centre with a thyroid nodule from 2007 to 2017 were retrospectively analyzed. Demographic and disease specific information were collected. CPV and adherence to ATA guidelines were explored. Results Of 86 patient records reviewed, 47 (55%) were managed operatively (mean age 14.4, 59F:27M). Fifteen patients (17%) had malignant pathology, and 11/15 (73%) were papillary carcinoma. Of the 47 operative patients, 7 (15%) had no preoperative ultrasound, and 12 patients (26%) did not have preoperative cytology. All patients with low TSH had scintigraphy appropriately performed, and 1 patient with high/normal TSH did not have a preoperative FNA obtained. All differentiated thyroid cancers were appropriately managed with hemithyroidectomy or total thyroidectomy based on pathology. Where CPV from the guidelines was noted, it was associated with complex presentation, the surgeon's decision to proceed to surgery directly, and/or rare pathologies. Conclusion The ATA guidelines provide a valuable framework for the management of pediatric thyroid nodules, but CPV persists given patient/disease complexity and heterogeneity.

This interactive session was held at the 51st Annual Meeting of the Canadian Association of Pediatric Surgeons (CAPS) in preparation for the transition of Pediatric Surgery training in Canada to Competency by Design (a CBME-based model of residency training developed by the Royal College of Physicians and Surgeons of Canada).

We conducted a multi-centre study to assess treatments and outcomes in a national cohort of infants with congenital ovarian cysts.Wide variability exists in the treatment of congenital ovarian cysts. The effects of various treatment strategies on outcomes, specifically ovarian preservation, are not known.Female infants diagnosed with congenital intra-abdominal cysts between 2013-2017 at 10 Canadian pediatric surgical centres were retrospectively evaluated. Sonographic characteristics, median time to cyst resolution, incidence of ovarian preservation, and predictors of surgery were evaluated. Subgroup analyses were performed in patients with complex cysts and cysts ≥40 mm in diameter.The study population included 189 neonates. Median gestational age at diagnosis and median maximal prenatal cyst diameter were 33 weeks and 40 mm, respectively. Cysts resolved spontaneously in 117 patients (62%), 14 (7%) prenatally and the remainder at a median age of 124 days. Intervention occurred in 61 patients (32%), including prenatal aspiration (2, 3%), ovary-sparing resection (14, 23%) or oophorectomy (45, 74%). Surgery occurred at a median age of 7.4 weeks. Independent predictors of surgery included postnatal cyst diameter ≥ 40 mm (OR 6.19, 95% CI 1.66 - 35.9) and sonographic complex cyst character (OR 63.6, 95% CI 10.9 - 1232). There was no significant difference in the odds of ovarian preservation (OR 3.06, 95% CI 0.86 - 13.2) between patients who underwent early surgery (n = 22) and those initially observed for at least 3 months (n = 131).Most congenital ovarian cysts are asymptomatic and spontaneously resolve. Early surgical intervention does not increase ovarian preservation.

Sclerotherapy is frequently employed in treating lymphatic malformations (LMs), and multiple agents, practitioners and strategies exist. This review investigates the reported efficacy and safety of sclerosants in the pediatric population.Adhering to PRISMA guidelines, multiple databases were queried without linguistic or temporal restriction. Inclusion criteria were patients aged 0-18 exclusively receiving injection sclerotherapy for the treatment of LMs with follow-up data. Data abstracted included agent, dose, anatomic site and key outcome measures including complications (major/minor) and resolution rates (95% reduction in volume). Critical appraisal was undertaken using the MINORS tool.Forty-eight studies met the inclusion criteria with a mean MINORS score of 0.65 ± 0.08. Included studies yielded 886 patients, across nearly 30 years. The overall observed rate of success was 89%, with variable follow-up across publications (6 weeks - 10 years). Most reported LMs were macrocystic (82%) and had a higher resolution rate than mixed/microcytic variants (89%, 71%, 34%, p0.01) For head/neck LMs, rates of complete regression for OK-432, bleomycin, and doxycycline were 67% ± 27% (n = 26), 91% ± 53% (n = 34) and 85% ± 16% (n = 52) respectively. Major complications were most commonly reported with OK-432, including airway compromise or subsequent operation.In pediatric patients treated for LM by sclerotherapy, complication rates were low. Macrocystic lesions respond well but success rates were modest at best for microcystic disease. Differences in agent utilization were noted between high and low resourced contexts; despite its lack of federal approval, OK-432 was the most reported agent. Further prospective research is warranted. LOE: 3a.

The origin of congenital abdominal cysts in the female fetus often dictates management. While most arise from the ovary and are often managed non-operatively, some are non-ovarian and are frequently removed. We analyzed a national sample of female infants with congenital abdominal cysts to elucidate prenatal and postnatal factors associated with the diagnosis of a non-ovarian cyst.A retrospective cohort study of female infants who were prenatally diagnosed with abdominal cysts between 2013 and 2017 at 10 Canadian pediatric surgical centres was performed. Clinical characteristics, pre- and postnatal sonographic findings, and cyst trajectories were compared between patients with proven ovarian etiology and those with cysts arising from other organs.Of 185 infants with prenatally diagnosed abdominal cysts, 22 (12%) were non-ovarian, five of which had clear non-ovarian organ of origin on prenatal ultrasound. Comparison of the other 17 cysts with 163 congenital ovarian cysts showed the following factors to be associated with a non-ovarian origin: earlier gestational age at diagnosis (23.5 vs 33.5 weeks, p0.001), smaller diameter on first prenatal ultrasound (15.8 vs. 39.7 mm, p0.001), change in sonographic character from simple to complex (87% vs 22%, p0.001), and postnatal sonographic characteristics of complex cyst (87% vs. 48%, p = 0.004).Clear organ of origin, diagnosis earlier in gestation, smaller initial prenatal cyst diameter, and sonographic cyst character change differentiate congenital non-ovarian cysts from their ovarian counterparts. These characteristics may be used to guide diagnosis and management.

Purpose The American Pediatric Surgical Association (APSA) guidelines for the treatment of isolated solid organ injury (SOI) in children were published in 2000 and have been widely adopted. The aim of this systematic review by the APSA Outcomes and Evidence Based Practice Committee was to evaluate the published evidence regarding treatment of solid organ injuries in children. Methods A comprehensive search strategy was crafted and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were utilized to identify, review, and report salient articles. Four principal questions were examined based upon the previously published consensus APSA guidelines regarding length of stay (LOS), activity level, interventional radiologic procedures, and follow-up imaging. A literature search was performed including multiple databases from 1996 to 2016. Results LOS for children with isolated solid organ injuries should be based upon clinical findings and may not be related to grade of injury. Total LOS may be less than recommended by the previously published APSA guidelines. Restricting activity to grade of injury plus two weeks is safe but shorter periods of activity restriction have not been adequately studied. Prophylactic embolization of SOI in stable patients with image-confirmed arterial extravasation is not indicated and should be reserved for patients with evidence of ongoing bleeding. Routine follow-up imaging for asymptomatic, uncomplicated, low-grade injured children with abdominal blunt trauma is not warranted. Limited data are available to support the need for follow-up imaging for high grade injuries. Conclusion Based upon review of the recent literature, we recommend an update to the current APSA guidelines that includes: hospital length of stay based on physiology, shorter activity restrictions may be safe, minimizing post-injury imaging for lower injury grades and embolization only in patients with evidence of ongoing hemorrhage. Type of Study Systematic Review. Levels of Evidence Levels 2–4.

Background Sclerotherapy is a commonly utilized treatment for rectal prolapse in children. This study systematically evaluates the effectiveness and complications of various sclerosing agents in treating pediatric rectal prolapse. Methods After protocol registration (CRD-42018088980), multiple databases were searched. Studies describing injection sclerotherapy for treatment of pediatric rectal prolapse were included, with screening and data abstraction duplicated. The methodological quality of included papers was assessed using the Methodological Index for Non-Randomized Studies (MINORS) score. Results Nineteen studies were identified, published between 1970 and 2017. Most studies were single institution case series, with median “N” 57 +/−88.9 and mean MINORS score of 0.51 +/−0.17 (perfect score = 1). 1510 patients with a mean age of 4.5 years were accounted for: 36.2% female, most without comorbidities. Mean follow up length was 30 months. The most common sclerosing agent described was ethanol (45%), followed by phenol (33%). The mean number of treatments per patient was 1.1 +/−0.34. The overall success rate after a single sclerotherapy treatment was 76.9%+/−8.8%. The overall complication rate was 14.4%+/−2%. Conclusions Injection sclerotherapy appears effective and low-risk in the treatment of pediatric rectal prolapse and should be considered before more invasive surgical options. The available evidence is of relatively poor quality, and prospective comparative investigations are warranted. Level of evidence 3 (meta-analysis of level 3 studies).

Background Treatment of the neonate with long gap esophageal atresia (LGEA) is one of the most challenging scenarios facing pediatric surgeons today. Contributing to this challenge is the variability in case definition, multiple approaches to management, and heterogeneity of the reported outcomes. This necessitates a clear summary of existing evidence and delineation of treatment controversies. Methods The American Pediatric Surgical Association Outcomes and Evidence Based Practice Committee drafted four consensus-based questions regarding LGEA. These questions concerned the definition and determination of LGEA, the optimal method of surgical management, expected long-term outcomes, and novel therapeutic techniques. A comprehensive search strategy was crafted and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were utilized to identify, review and report salient articles. Results More than 3000 publications were reviewed, with 178 influencing final recommendations. In total, 18 recommendations are provided, primarily based on level 4–5 evidence. These recommendations provide detailed descriptions of the definition of LGEA, treatment techniques, outcomes and future directions of research. Conclusions Evidence supporting best practices for LGEA is currently low quality. This review provides best recommendations based on a critical evaluation of the available literature. Based on the lack of strong evidence, prospective and comparative research is clearly needed. Type of study Treatment study, prognosis study and study of diagnostic test. Level of evidence Level II–V.

Background The Lancet Commission on Global Surgery highlighted global surgical need but offered little insight into the specific surgical challenges of children in low-resource settings. Efforts to strengthen the quality of global pediatric surgical care have resulted in a proliferation of partnerships between low-and middle-income countries (LMICs) and high-income countries (HICs). Standardized tools able to reliably measure gaps in delivery and quality of care are important aids for these partnerships. We undertook a systematic review (SR) of capacity assessment tools (CATs) focused on needs assessment in pediatric surgery. Methods A comprehensive search strategy of multiple electronic databases was conducted per PRISMA guidelines without linguistic or temporal restrictions. CATs were selected according to pre-defined inclusion criteria. Articles were assessed by two independent reviewers. Methodological quality of studies was appraised using the COSMIN checklist with 4-point scale. Results The search strategy generated 16,641 original publications, of which three CATs were deemed eligible. Eligible tools were either excessively detailed or oversimplified. None used weighted scores to identify finer granularity between institutions. No CATs comprehensively included measures of resources, outcomes, accessibility/impact and training. Discussion The results of this study identify the need for a CAT capable of objectively measuring key aspects of surgical capacity and performance in a weighted tool designed for pediatric surgical centers in LMICs. Type of Study Systematic Review. Level of Evidence II.

There is a significant unmet need for children’s surgical care in low- and middle-income countries (LMICs). Multidisciplinary collaboration is required to advance the surgical and anesthesia care of children’s surgical conditions such as congenital conditions, cancer and injuries. Nonetheless, there are limited examples of this process from LMICs. We describe the development and 3-year outcomes following a 2015 stakeholders’ meeting in Uganda to catalyze multidisciplinary and multi-institutional collaboration. The stakeholders’ meeting was a daylong conference held in Kampala with local, regional and international collaborators in attendance. Multiple clinical specialties including surgical subspecialists, pediatric anesthesia, perioperative nursing, pediatric oncology and neonatology were represented. Key thematic areas including infrastructure, training and workforce retention, service delivery, and research and advocacy were addressed, and short-term objectives were agreed upon. We reported the 3-year outcomes following the meeting by thematic area. The Pediatric Surgical Foundation was developed following the meeting to formalize coordination between institutions. Through international collaborations, operating room capacity has increased. A pediatric general surgery fellowship has expanded at Mulago and Mbarara hospitals supplemented by an international fellowship in multiple disciplines. Coordinated outreach camps have continued to assist with training and service delivery in rural regional hospitals. Collaborations between disciplines, both within LMICs and with international partners, are required to advance children’s surgery. The unification of stakeholders across clinical disciplines and institutional partnerships can facilitate increased children’s surgical capacity. Such a process may prove useful in other LMICs with a wide range of children’s surgery stakeholders.

Conservative treatment of pectus excavatum with a vacuum bell device may be an attractive alternative to surgical repair. We describe an early North American experience with this device.Prospectively maintained chest wall clinic registries from two institutions were reviewed to identify pectus excavatum patients ≤21 years treated with the vacuum bell from 2013 to 2017. Multivariate linear regression was used to compare mean improvements in deformity-depth and Haller Index between groups of patients based on age and usage metrics (hours/day and days/week).Thirty-one patients with a median age of 14 years received treatment with the device. Mean follow-up duration was 18 months. Median depth and Haller Index at treatment onset were 2.3 cm and 3.9, respectively. Improvements in deformity-depth were superior with device usage2 h/day (p 0.01) and daily use (p 0.01). After adjusting for compliance, younger age of treatment onset was associated with greater improvement in Haller Index but not deformity depth.Our prospective early North American experience found the vacuum bell to be a potential alternative to surgical treatment for pectus excavatum. Longer usage periods in a daily frequency are associated with best results.Treatment study; case series with no comparison group.Level IV.

Purpose Postoperative pain remains a considerable concern for patients and families. We assessed whether nebulized ropivacaine reduces morphine consumption and pain after laparoscopic appendectomy for uncomplicated appendicitis in children. Methods Patients 7–17 years old with uncomplicated appendicitis were randomized to ropivacaine (intervention arm) or saline nebulization (placebo arm) at the onset of laparoscopy. Nonconsenting individuals were treated with standard care and invited to provide clinical data (baseline arm). The primary outcome was in-patient morphine utilization. Secondary outcomes included pain scores at multiple time-points, markers of recovery, operative times, and surgeon satisfaction. The trial was registered ( NCT02624089 ). Results Study enrollment was 116 patients over a 1-year period: Intervention (n = 43), Placebo (n = 39), Baseline (n = 34). No differences in baseline characteristics were noted between groups. No difference was noted in overall in-patient morphine consumption between randomized groups (0.31 vs. 0.35 mg/kg, p = 0.42) or between ropivacaine and baseline (0.31 vs. 0.277 mg/kg, p = 0.62). Although operative times were comparable between groups, 63% of surgeon respondents felt that nebulization obscured visualization. Conclusion Nebulized ropivacaine did not reduce postoperative morphine consumption or pain scores after laparoscopic appendectomy for simple appendicitis in children. Given that it decreases visualization and likely increases costs, nebulized administration of intraperitoneal analgesia does not appear warranted in this context. Type of study Treatment study. Level of evidence Level I.

This is a commentary on the manuscript by Harrington A, Riebold J, Hernandez K, et al., titled “Nutrition Delivery and Growth Outcomes in Infants with Long-Gap Esophageal Atresia Who Undergo the Foker Process”.

The Northern Territory (NT) is a geographically remote region of northern and central Australia. Approximately a third of the population are First Nations Australians, many of whom live in remote regions. Due to the physical environment and climate, and scale of social inequity, the rates of many infectious diseases are the highest nationally. Molecular typing and genomic sequencing in research and public health have provided considerable new knowledge on the epidemiology of infectious diseases in the NT. We review the applications of genomic sequencing technology for molecular typing, identification of transmission clusters, phylogenomics, antimicrobial resistance prediction, and pathogen detection. We provide examples where these methodologies have been applied to infectious diseases in the NT and discuss the next steps in public health implementation of this technology.

Systematic reviews (SRs) are a form of research methodology that addresses a specific research question by collecting, appraising and summarising all empirical evidence that fits pre-specified eligibility criteria. Systematic reviews have grown exponentially since their emergence in the late 1970 s as evidence-based medicine permeated medical culture. With several key advantages and limitations inherent to their design, all health care providers should be familiar with their basic structure, how to critically appraise them, and how to incorporate their findings into clinical practice. This review will contextualise systematic reviews within the broader framework of other review types, and outline the steps in conducting or appraising a systematic review. This includes the framing of an appropriate question, the search strategy, appraisal of included studies, as well as synthesis and analysis of the acquired data. A focus on SRs in the context of pediatric surgical practice will be emphasized. A concise primer on meta-analytic techniques is also provided, with resources highlighted for further reading.

In 2015, the Lancet Commission on Global Surgery published six global surgery goals, one of which was to provide 80% of the world’s population with timely access to the Bellwether Surgical procedures. Little is known about the prevalence or efficacy of subsequent interventions implemented in under-resourced countries to increase timely access to Bellwether surgical procedures. A systematic review of articles and grey literature published in MEDLINE, Embase, Cochrane, CINAHL, and Web of Science databases was conducted. Two independent reviewers evaluated 1923 captured abstracts using explicit inclusion and exclusion criteria. Following a thematic analysis, two reviewers conducted data extraction on the eleven manuscripts included in the final review. The studied innovations, sparse in number, centred on improved educational resources, the development of orthopaedic devices, and models for assessing surgical access disparity. Eight papers were centred around timely access to caesarean sections, three around open fracture reduction, and three around laparotomy; all focused on adult populations. Five papers addressed innovations in West Africa, two in East Africa, two in South Asia, and one in Southeast Asia. Common outcome metrics were not used to assess improvements to timely surgical access. Few published interventions have been implemented since the publication of the 2015 Lancet Commission on Global Surgery goals that have or will longitudinally increase the availability of timely surgical access in Low and Middle-Income Countries (LMIC). Tangible outcome measures in existing literature are lacking. An up-scaling and wider adoption of successful strategies is necessary and possible.

Background Significant limitations in pediatric surgical capacity exist in low- and middle-income countries, especially in rural regions. Recent global children’s surgical guidelines suggest training and support of general surgeons in rural regional hospitals as an effective approach to increasing pediatric surgical capacity. Methods Two years of a prospective clinical database of children’s surgery admissions at 2 regional referral hospitals in Uganda were reviewed. Primary outcomes included case volume and clinical outcomes of children at each hospital. Additionally, the disability-adjusted life-years averted by delivery of pediatric surgical services at these hospitals were calculated. Using a value of statistical life calculation, we also estimated the economic benefit of the pediatric surgical care currently being delivered. Results From 2016 to 2019, more than 300 surgical procedures were performed at each hospital per year. The majority of cases were standard general surgery cases including hernia repairs and intussusception as well as procedures for surgical infections and trauma. In-hospital mortality was 2.4% in Soroti and 1% in Lacor. Pediatric surgical capacity at these hospitals resulted in over 12,400 disability-adjusted life-years averted/year. This represents an estimated economic benefit of 10.2 million US dollars/year to the Ugandan society. Conclusion This investigation demonstrates that lifesaving pediatric procedures are safely performed by general surgeons in Uganda. General surgeons who perform pediatric surgery significantly increase surgical access to rural regions of the country and add a large economic benefit to Ugandan society. Overall, the results of the study support increasing pediatric surgical capacity in rural areas of low- and middle-income countries through support and training of general surgeons and anesthesia providers.

Objective: In infants with gastroschisis, outcomes were compared between those where operative reduction and fascial closure were attempted ≤24 hours of age (PC), and those who underwent planned closure of their defect >24 hours of age following reduction with a pre-formed silo (SR). Summary of Background Data: Inadequate evidence exists to determine how best to treat infants with gastroschisis. Methods: A secondary analysis was conducted of data collected 2006–2008 using the British Association of Pediatric Surgeons Congenital Anomalies Surveillance System, and 2005–2016 using the Canadian Pediatric Surgery Network. 28-day outcomes were compared between infants undergoing PC and SR. Primary outcome was number of gastrointestinal complications. Interactions were investigated between infant characteristics and treatment to determine whether intervention effect varied in sub-groups of infants. Results: Data from 341 British and Irish infants (27%) and 927 Canadian infants (73%) were used. 671 infants (42%) underwent PC and 597 (37%) underwent SR. The effect of SR on outcome varied according to the presence/absence of intestinal perforation, intestinal matting and intestinal necrosis. In infants without these features, SR was associated with fewer gastrointestinal complications [aIRR 0.25 (95% CI 0.09–0.67, P = 0.006)], more operations [aIRR 1.40 (95% CI 1.22–1.60, P < 0.001)], more days PN [aIRR 1.08 (95% CI 1.03–1.13, P < 0.001)], and a higher infection risk [aOR 2.06 (95% CI 1.10–3.87, P = 0.025)]. In infants with these features, SR was associated with a greater number of operations [aIRR 1.30 (95% CI 1.17–1.45, P < 0.001)], and more days PN [aIRR 1.06 (95% CI 1.02–1.10, P = 0.003)]. Conclusions: In infants without intestinal perforation, matting, or necrosis, the benefits of SR outweigh its drawbacks. In infants with these features, the opposite is true. Treatment choice should be based upon these features.

Comparing adverse outcomes following alternative surgical interventions is a complex process for both patients and providers. Disability-adjusted life years (DALYs) are used globally as a quantitative indicator of burden of disease. However, DALYs have not been applied to the burden of postoperative complications. This study explores the feasibility and utility of DALYs in measuring the burden of postoperative complications, using 2 pediatric surgical procedures as a test model.A literature review was undertaken of postoperative complications following pediatric inguinal hernia repair and intestinal atresia repair. Relevant studies were included, and incidence rates and durations of all key complications were identified. Using existing disability weights of equivalent health states to the complications, we estimated the burden in DALYs of each complication. These estimates were combined into a unitary procedure-specific complication burden score.The key complications contributing to the postoperative burden following inguinal hernia repair were recurrence (0.016 DALYs), hydrocele (0.010), metachronous hernia (0.014) and port-site hernia (0.012). In the case of intestinal atresia repair, death (6.278), reoperation (12.100), stenosis (5.025) and anastomotic stricture (5.327) accounted for most of the postoperative DALYs. The complication burden score was 0.06 DALYs for inguinal hernia and 36.86 for intestinal atresia repair.As a proof of concept, this study supports the feasibility of using DALYs to derive a complication burden score following surgical intervention, and to our knowledge it represents the first application of burden of disease metrics to postoperative adverse outcomes. Future studies should focus on deriving de novo disability weights for common postoperative complications and adverse outcomes.La comparaison des issues indésirables découlant d’interventions chirurgicales de substitution est complexe, tant pour les patients que pour les fournisseurs de soins. Partout au monde, les années de vie ajustées en fonction de l’incapacité (AVAI) sont utilisées comme indicateur quantitatif du fardeau de la maladie. Or, les AVAI n’ont jamais été appliquées au fardeau des complications postopératoires. La présente étude porte sur la faisabilité et l’utilité du recours aux AVAI pour mesurer le fardeau des complications postopératoires. Elle se sert de 2 interventions chirurgicales pédiatriques comme modèles.Nous avons mené une revue de la littérature sur les complications postopératoires suivant une réparation de hernie inguinale et une correction d’atrésie intestinale chez des populations pédiatriques. Nous avons retenu les études pertinentes et dégagé le taux d’incidence ainsi que la durée des principales complications. Nous nous sommes également servis du fardeau pondéré de l’incapacité liée à un trouble de santé équivalent à chacune des complications pour estimer le fardeau, en AVAI, des complications. Les estimations ont ensuite été combinées pour obtenir un score unitaire correspondant au fardeau des complications associées à chaque intervention.Les principales complications contribuant au fardeau postopératoire associé à la réparation de hernie inguinale étaient la récurrence (0,016 AVAI), l’hydrocèle (0,010 AVAI), la hernie métachrone (0,014 AVAI) et la hernie au site de laparoscopie (0,012). En ce qui a trait à la correction d’atrésie intestinale, le décès (6,278 AVAI), la réopération (12,100 AVAI), la sténose (5,025 AVAI) et le rétrécissement anastomotique (5,327 AVAI) étaient à l’origine de la plupart des AVAI postopératoires. Le score du fardeau des complications était de 0,06 AVAI pour la réparation de hernie inguinale et de 36,86 AVAI pour la correction d’atrésie intestinale.Cette étude, comme validation de principe, montre qu’il est possible d’utiliser les AVAI pour obtenir un score correspondant au fardeau des complications associées à une intervention chirurgicale. Elle est également la première, à notre connaissance, à appliquer un score de fardeau de la maladie aux issues postopératoires indésirables. Des études ultérieures devraient être axées sur le calcul de nouveaux fardeaux pondérés pour les complications postopératoires et les issues indésirables courantes.

Bartonella henselae is a zoonotic Gram-negative Bacillus associated with self-limited regional lymphadenopathy. In recent decades, an expanding spectrum of clinical manifestations has been described, in part, due to improved diagnostics. However, updated epidemiological data are sparse. We retrospectively reviewed the clinical features of 31 patients with B. henselae infection over 15 years from 2005 to 2019, in the tropical Top End of Australia. Our annual disease incidence of 1.3 cases per 100,000 population is lower than that in the national database surveillances in the United States, but the hospitalization incidence of 0.9 per 100,000 population in our region is higher than those reported in the literature, with an average length of stay of 9 days. Patients were more commonly male, aboriginal, and aged less than 14 years (median age: 7 years), living in a rural setting with presentation during our monsoon season. The disease spectrum included lymph node disease (74%), organ peliosis, endocarditis, cutaneous lesions, parapharyngeal abscess, parotitis, and neurologic and ocular syndromes. Lymph node disease was far commoner in children than the more serious systemic B. henselae infections associated with adults (P = 0.074). Although no deaths were reported, significant morbidities were observed. Two endocarditis cases presented with glomerulonephritis, and hematological and neurological features mimicking vasculitis, and consequently received immunosuppressants. One case was only diagnosed after representation with serial embolic strokes. Given the heterogeneity of disease manifestations with nonspecific symptoms and significant consequences, a timely and accurate diagnosis is needed to avoid unnecessary treatments or interventions.

We report a series of 20 neonates and infants (18 born preterm) who underwent laparoscopic inguinal hernia repair with caudal anesthesia, oxygen via nasal cannula, and intravenous anesthesia. Surgery was successful in all cases without airway instrumentation or intraoperative complications. Sedation was provided with dexmedetomidine, propofol, and remifentanil. Two patients had apnea in the following 24 hours. There were no unplanned intensive care admissions. Laparoscopy allowed unplanned bilateral repair in 2 cases. Caudal with intravenous anesthesia without airway instrumentation is a viable technique for laparoscopic inguinal hernia repair. Avoiding general endotracheal anesthesia may reduce perioperative complications and influence postoperative disposition.

The pediatric resuscitation and trauma outcome (PRESTO) model was developed to aid comparisons of risk-adjusted mortality after injury in low- and middle-income countries (LMICs). We sought to validate PRESTO using data from a middle-income country (MIC) trauma registry and compare its performance to the Pediatric Trauma Score (PTS), Revised Trauma Score, and pediatric age-adjusted shock index (SIPA). We included children (age

This study aims to compare the prevalence and outcomes of surgically correctable congenital anomalies between sexes.Upon registration on PROSPERO (CRD42019120165), a librarian aided in conducting a systematic review using PRISMA guidelines. The five largest relevant studies were included for each anomaly. Cumulative prevalence differences and confidence intervals were calculated, and the Cochran-Mantel-Haenszel test was performed.Of 42,722 identified studies, 68 were included in our analysis. All included anomalies had greater than 1000 patients except duodenal atresia (n = 787) and intestinal duplication (n = 148). Males had a significantly higher prevalence than females in 10/14 anomalies (Hirschsprung's disease, omphalomesenteric duct, congenital diaphragmatic hernia, anorectal malformation, malrotation, esophageal atresia, congenital pulmonary airway malformation, intestinal atresia, omphalocele, and gastroschisis; p 0.001). There was no difference in the prevalence of duodenal atresia or intestinal duplication between sexes (p = 0.88 and 0.65, respectively). Females had a significantly higher prevalence of biliary anomalies (atresia and choledochal cyst).Our study indicates that males have higher prevalence rates of most congenital anomalies. Further investigations are required to illuminate the embryology underlying this sex distribution and whether sex influences outcomes.Systematic review and meta-analysis.Prognostic study, level II.

Purpose We sought to identify implementation barriers and opportunities to increase utilization of the Canadian Congenital Diaphragmatic Hernia (CDH) Collaborative's clinical practice guideline. Methods A validated readiness assessment was sent via SurveyMonkey™ to CAPSNet site coordinators and local CDH stakeholders. The survey was open from 11/2018 to 02/2019. Data and responses were analyzed using descriptive statistics (REB 2019-4753). Results Eighty-six responses were received, of which 65% (n = 56/86) were fully completed. The greatest number of responses came from neonatology (n = 27), pediatric surgery (n = 25), and respiratory therapy (n = 10). Seventy-eight percent (n = 67/86) of respondents were aware of the CDH guideline, and 63% (n = 54/86) used the entire guideline, while 23% (n = 20/86) used only certain sections. Besides recommendations pertaining to fetal intervention and ECLS, interdisciplinary long-term surveillance and prenatal diagnosis were considered most difficult to implement owing to funding limitations. Most respondents (n = 49/56; 87.5%) felt they could implement > 75% of the recommendations. Establishing common team goals [i.e., minimize care variations] (n = 33/58;57%), provider buy-in [commitment of all health professionals to the guideline] (n = 28/58;48%), and regular compliance assessment (n = 23/58;40%) would increase uptake. Conclusion There is national awareness of the CDH guideline. Implementation strategies ensuring common team goals, provider buy-in, and regular compliance assessment should increase guideline uptake/utilization. Consolidating funding for interdisciplinary long-term surveillance and prenatal diagnosis is necessary for any site-specific implementation strategy. Level of evidence Level 4 qualitative, survey.

Background The utility of magnetic resonance imaging (MRI) in the diagnosis and management of pediatric ovarian lesions has not been well defined. Methods A retrospective review of all girls who underwent MRI evaluation of ovarian masses during the period 2009–2015 was performed. The accuracy of MRI was evaluated by comparing results with surgical findings, pathology reports, and subsequent imaging. The influence of the MRI on the treatment plan was specifically explored. Results Eighteen girls, 12–17years of age, underwent 27 MRIs, subsequent to ultrasound identification of ovarian lesions. Of 9 neoplastic lesions diagnosed on MRI, 8 (89%) were confirmed by surgical and pathological findings. Of 18 functional lesions, 17 (94.4%) were confirmed pathologically or by resolution on subsequent imaging. Twenty MRI exams (74%) directly influenced the treatment plan, by leading to appropriate operative intervention in 9 and appropriate observation in 11. The extent of ovarian resection was guided by MRI findings in 8 of 9 (89%) neoplastic lesions. For characterizing lesions as neoplastic, the sensitivity, specificity, negative predictive value, positive predictive value, and accuracy of MRI were 89%, 94%, 94%, 89%, and 93% respectively. Conclusions MRI can differentiate functional from neoplastic pediatric ovarian masses, and guide ovarian resection in appropriate cases. Level of study II

Background Pediatric surgical randomized clinical trials (RCTs) are labor-intensive and costly. This systematic review investigated patient accrual and estimates of study duration in RCTs by interrogating enrollment and registration practices. Methods We performed a peer-review search of multiple databases from 2000 to 2016 evaluating RCTs salient to the field with inclusion mandated that a self-identified pediatric surgeon be listed as an author. Trial registries were also searched. RCTs were appraised, and predictors of success were evaluated using multivariate logistic regression, with success defined as achievement of recruitment objectives. Results After screening, 137 RCTs were analyzed. Mean Jadad score was 1.80 (median=2). CONSORT scores ranged between 17% and 97% (median=58%). Sixty-seven studies described sample-size determination, 49 reported projected enrollment, and 26 were successful. Among 26 registered RCTs, 15 disclosed their expected completion date, which was achieved by 8. On average, protocols underwent 3.42 iterations. 9% of trials were terminated before completion, most commonly owing to poor recruitment. Trial registration and urgent cases significantly predicted success on multivariable analysis (p Conclusion Overall quality of reporting in pediatric surgical trials is poor. Sample-size calculation and patient accrual are frequently poorly performed or underestimated, resulting in trial overrun and/or premature termination. These data may help inform subsequent study design and facilitate successful completion. Level of Evidence Level III—Systematic Review and Observational (Case–Control) Analysis.

Background Gastrostomy tubes are a common adjunct to the care of vulnerable pediatric patients. This study systematically evaluates the epidemiology and risk-factors for gastrocutaneous fistulae (GCF) after gastrostomy removal in children and reviews treatment options focusing on nonoperative management (NOM). Methods After protocol registration (CRD-42017059565), multiple databases were searched. Studies describing epidemiology in children and GCF treatment at any age were included. Critical appraisal was performed (MINORS risk-of-bias assessment tool). One-sided meta-analysis was executed to estimate efficacy of therapeutic adjuncts using a random-effects model. Results Sixteen articles evaluating pediatric GCF were identified. 44% defined GCF as persistence >1month which occurred in 31±7% of cases. Risk factors for pediatric GCF include age at gastrostomy, timing of removal, open technique, and fundoplication. Mean MINORS score was 0.60±0.16. Seventeen additional studies were identified reporting 142 patients undergoing NOM (endoscopic, systemic, and local therapies), and one pediatric comparative study was identified. Overall aggregate proportion of GCF closure after any NOM is 77% (80% success rate in local/systemic therapies; 75% success rate in endoscopic approaches). No adverse events were reported. Conclusion Persistent GCF complicates the management of gastrostomies in 1/3 of children with predictable risk factors. Several treatment options exist that obviate the need for general anesthesia. Their efficacy is unclear. Further prospective investigations are clearly warranted. Level of Evidence III — Systematic Review and Meta-Analysis Based on Retrospective Case Control Studies.

Purpose Despite a wide spectrum of severity, perforated appendicitis in children is typically considered a single entity in outcomes studies. We performed a prospective cohort study to define a risk stratification system that correlates with outcomes and resource utilization. Methods A prospective study was conducted of all children operated for perforated appendicitis between May 2015 and December 2016 at a tertiary free-standing university children's hospital. Surgical findings were classified into one of four grades of perforation: I. localized or contained perforation, II. Contained abscess with no generalized peritonitis, III. Generalized peritonitis with no dominant abscess, IV. Generalized peritonitis with one or more dominant abscesses. All patients were treated on a clinical pathway that involved all points of care from admission to final follow-up. Outcomes and resource utilization measures were analyzed using Fisher's exact test, Kruskal–Wallis test, One-way ANOVA, and logistic regression. Results During the study period, 122 patients completed treatment, and 100% had documented follow-up at a median of 25days after operation. Grades of perforation were: I, 20.5%; II, 37.7%; III, 10.7%; IV, 31.1%. Postoperative abscesses occurred in 12 (9.8%) of patients, almost exclusively in Grade IV perforations. Hospital stay, duration of antibiotics, TPN utilization, and the incidence of postoperative imaging significantly increased with increasing grade of perforation. Conclusion Outcomes and resource utilization strongly correlate with increasing grade of perforated appendicitis. Postoperative abscesses, additional imaging, and additional invasive procedures occur disproportionately in patients who present with diffuse peritonitis and abscess formation. The current stratification allows risk-adjusted outcome reporting and appropriate assignment of resource burden. Level of evidence I (Prognosis Study).
