A minimally invasive hybrid procedure to correct pectus arcuatum.

BACKGROUND: Pectus arcuatum, also known as horns of steer anomaly or Currarino-Silverman Syndrome, is a distinct chest wall anomaly characterized by severe manubriosternal angulation, a shortened sternum, and mild pectus excavatum. The anomaly is typically repaired using open techniques, employing orthopedic fixation devices. Here, we report the results of a minimally invasive hybrid procedure to repair pectus arcuatum. METHODS: The procedure combines a standard Nuss procedure to correct the depressed sternum with a short upper chest (in boys) or inter-mammary (in girls) incision for bilateral subperichondrial resection of the upper costal cartilages, osteotomy, and correction of the manubrial angulation. The medical records of all patients who underwent the procedure over the last 10 years were reviewed. RESULTS: Five patients, 3 boys and 2 girls, aged 14 to 17 years, underwent the procedure. Three patients had their pectus bars removed 3-4 years after repair. Follow-up after correction ranged from 6 months to 7 years. Good correction resulted in all patients achieving recovery without complications and recurrence. To date, all patients have been satisfied with their results. CONCLUSIONS: The minimally invasive hybrid procedure adequately corrects pectus arcuatum with minimal scarring and high satisfaction.

Laparoscopy in Low- and Middle-Income Countries: A Survey Study.

INTRODUCTION: An increasing shift towards non-communicable diseases and an existing high surgical burden of disease in low-middle-income countries (LMICs) has impelled the need for implementing laparoscopic surgery, a safe and cost-effective surgical service. However, despite countless benefits, laparoscopic surgery programs remain limited throughout LMICs, and limited understanding is known of healthcare professionals' views regarding the implementation of laparoscopic surgery in their local healthcare environments. Therefore, the purpose of this study is to better understand the perceived challenges and barriers to implementing long-term laparoscopic surgery programs from the perspective of healthcare professionals. METHODS: Upon receiving ethical approval from the McGill University Health Center (MUHC), a nine-question survey (concerning attributes required to establish a successful laparoscopic program in LMICs and to gain insight into what surgeons from LMICs believed were the necessary next steps) was pilot tested amongst faculty members, and subsequently disseminated to healthcare professionals practicing in LMICs. Explicit consent was obtained from the participants before answering the survey.  Results: Thirty-four participants representing a total of 35 countries participated in the survey with the majority having received laparoscopic surgery training. Overall, participant responses were characterized by two major themes. Highlighted in the first theme, Laparoscopic Experience and Training Curriculum, were responses concerning current laparoscopic training and education, improved career opportunities provided by laparoscopic training, and a particular existing potential to incorporate laparoscopic surgery into the current surgical curriculum at various levels of training. Emphasized in the second theme, Challenges and Next Steps, were responses concerning barriers to the implementation of laparoscopic surgery, current institutional capabilities, and the need for improving mentorship through existing surgical societies such as the College of Surgeons of East, Central, and Southern Africa (COSECSA), West African College of Surgeons (WACS), and The Pan-African Academy of Christian Surgeons (PAACS). CONCLUSIONS: A buy-in from the government, hospitals, staff, and industry is crucial for the long-term implementation of laparoscopic surgery in LMICs, which can only be accomplished through increased advocacy and the dissemination of the benefits of minimally invasive surgery both economically and socially.

External validation of the PRESTO pediatric tool for predicting in-hospital mortality from traumatic injury.

BACKGROUND: Benchmarking is crucial for quality improvement of trauma systems. The Pediatric Resuscitation and Trauma Outcome (PRESTO) model allows risk-adjusted comparisons of in-hospital mortality for pediatric trauma populations in under-resourced environments. Our aim was to validate PRESTO in a high-resource setting using provincial Trauma Registry (TR) data and compare it to the standard benchmarking model, the Injury Severity Score (ISS). METHODS: This retrospective case-control study collected demographic, vital sign, and outcome data from the TR for patients aged <16 years sustaining major trauma from 2013 to 2021. The PRESTO model estimates predicted probability of in-hospital mortality (Pm) using the age, heart rate, blood pressure, oxygen saturation, neurological status, and use of airway supplementation. PRESTO was assessed by comparison of Pm in patients who died and survived and comparison of area under the receiver-operator curve (AUROC) with that of ISS. Statistical analysis was performed using R. RESULTS: We included 647 patients, of which 69 died in-hospital (11%). The cohort was 37% female, with a median age of 8 and median ISS of 17. The median Pm for cases was significantly higher compared to controls (1.0 vs. 5.2 × 10-5, p < 0.001). The AUROC for PRESTO and ISS were not significantly different (0.819 and 0.816, respectively; p = 0.95). CONCLUSION: PRESTO is valid in a resource-rich environment, such as a Canadian province. It performs equally well to ISS but is simpler to derive. In the future, PRESTO may serve to benchmark levels of in-hospital mortality within or across institutions over time across Canada.

Definitive Care for Severely Injured Children in Quebec.

INTRODUCTION: Injury is the leading cause of death in children over the age of one in Canada, and remains the most common cause of death in Quebec pediatric patients. Indigenous communities are 3-4 times more likely to be affected by injuries than the national average. In Quebec, health centres can range from 30 to 1000 km away from the closest level I trauma center. METHODS: Descriptive analysis and multiple logistic regression were performed for severely injured pediatric trauma patients received at the Montreal Children's Hospital (MCH) over a ten-year period. Outcomes were compared between regional groups in Quebec using forward sortation areas. RESULTS: Two hundred and forty four pediatric patients presented to the MCH with major trauma between 2006 and 2016. Of those, 42% of patients resided in Montreal, 42% off-island, and 16% in Northern Quebec. Admission to the Intensive Care Unit (ICU) was required for 60% of off-island patients and 58% of Northern residents. The median length of hospital stay (LOS) was 5 days for off-island and 15 days for Northern patients. Most patients (78% off-island vs. 76% Northern Quebec) were discharged home. The overall mortality was 5%. In multiple regression analysis, residence in Northern Quebec was associated with increased incidence of longer than median length of stay compared to off-island patients (OR 2.78, 95%CI (1.12-7.29)) after adjusting for injury severity, operative intervention, age, and sex. CONCLUSION: ICU admission rate was similar among Northern and off-island populations. Patients from Northern Quebec appeared to have longer-than-median hospital length of stay. In-hospital mortality was infrequent and limited to on-island and off-island populations. A further exploration of this data is required to identify the "trauma deserts" and advocate for children involved in trauma in all areas of Quebec.

The utility of echocardiography and pulmonary function testing in the preoperative evaluation of pectus excavatum.

PURPOSE: Echocardiography (ECHO) and pulmonary function testing (PFT) are routinely performed during the preoperative evaluation of pectus excavatum (PE). We hypothesized that these investigations may be performed selectively based on patient symptoms and pectus severity. METHODS: A retrospective review of all PE patients who underwent a Nuss procedure during a 15-year period (2004-2018) was conducted. Symptoms, clinical characteristics, ECHO, and PFT results were extracted from the medical chart. PE severity on computed tomography was measured using the Haller Index (HI) and Correction Index (CI), and reported as mean ± SEM. Logistic and linear regression assessed the ability of symptoms and indices to predict abnormal cardiopulmonary test results. RESULTS: Of 119 patients, 116 patients had symptom documentation, and 74 (64%) had one or more symptoms. HI and CI were 3.8 ± 1.0 and 31.6 ± 10.3, respectively. Of those with ECHO available (111), 14 (13%) were abnormal, and 12 of 14 required cardiology follow-up. Of those with PFT available (90), the results were abnormal in 15 (17%), including 9 (11%) obstructive, 4 (5%) restrictive, and 2 (2%) mixed. The presence of symptoms did not predict abnormal ECHO or PFT, but each standard deviation increase in the CI was associated with abnormal PFT and ECHO by a factor of 2.2 and 2.0 respectively. HI severity was only associated with ECHO. CONCLUSION: The rates of abnormal ECHO and PFT testing in PE patients are low, and do not correlate with symptoms. Routine ECHO is still recommended to detect anomalies requiring follow-up. Elevated CI severity may be used to guide selective PFT testing. LEVELS OF EVIDENCE: Retrospective Study, Level III.

Systematic review of grading systems for adverse surgical outcomes.

Background: Grading scales for adverse surgical outcomes have been poorly characterized to date. The primary aim of this study was to conduct a systematic review to enumerate the various frameworks for grading adverse postoperative outcomes; our secondary objective was to outline the properties of each grading system, identifying its strengths and weaknesses. Methods: We searched 9 databases (Africa Wide Information, Biosis, Cochrane, Embase, Global Health, LILACs, Medline, PubMed and Web of Science) from 1992 (the year the Clavien-Dindo classification system was developed) until Mar. 2, 2017, for studies that aimed to develop or improve on an already existing generalizable system for grading adverse postoperative outcomes. Study selection was duplicated as per PRISMA recommendations. Procedure-specific grading systems were excluded. We assessed the framework, strengths and weaknesses of the systems qualitatively. Results: We identified 9 studies on 8 adverse outcome grading systems with frameworks generalizable to any surgical procedure. Most systems have not been widely incorporated in the literature. Seven of the 8 systems were produced without including patients' perspectives. Four allowed the derivation of a composite morbidity score, which had limited tangible significance for patients. Conclusion: Although each instrument identified offered its own advantages, none satisfied the need for a patient-centred tool capable of generating a composite score of all possible postoperative adverse outcomes (complications, sequelae and failure) that enables comparison of noninterventional and surgical management of disease. There is a need for development of a more comprehensive, patient-centred grading system for adverse postoperative outcomes.

Contexte: Jusqu'ici, les systèmes de classification des issues postopératoires indésirables n'ont pas encore fait l'objet d'une analyse comparative. Cette étude avait pour objectif principal de recenser, au moyen d'une revue systématique de la littérature, les divers systèmes de classification des issues postopératoire indésirables, et pour objectif secondaire de dégager les propriétés, les forces et les faiblesses de chaque système. Méthodes: Nous avons interrogé 9 bases de données (Africa Wide Information, Biosis Previews, Cochrane, Embase, Global Health, LILACS, Medline, PubMed et Web of Science) pour trouver des articles publiés entre 1992 (année de la mise au point du système de classification de Clavien­Dindo) et le 2 mars 2017. Ces articles devaient porter sur la création d'un système généralisable de classification des issues postopératoires indésirables, ou l'amélioration d'un système existant. La sélection des études a été faite en double, conformément aux recommandations PRISMA. Les systèmes de classification visant une seule intervention ont été exclus. Nous avons évalué, d'un point de vue qualitatif, le cadre, les forces et les faiblesses des systèmes retenus. Résultats: Nous avons retenu 9 études sur 8 systèmes de classification accompagnés d'un cadre pouvant être appliqué à n'importe quelle intervention chirurgicale. La plupart des systèmes n'avaient pas été largement étudiés. Sept des 8 systèmes avaient été développés sans tenir compte du point de vue des patients, et 4 permettaient de calculer un score de morbidité composite ayant des retombées concrètes limitées pour les patients. Conclusion: Tous les systèmes retenus s'accompagnaient d'avantages, mais aucun ne pouvait servir d'outil centré sur le patient permettant de calculer un score composite pour toutes les issues postopératoires possibles (complications, séquelles et échec), score qui pourrait servir à comparer les prises en charge conservatrice et chirurgicale des maladies. La création d'un système de classification des issues postopératoires indésirables exhaustif centré sur le patient est nécessaire.

Comparison of the Pediatric Resuscitation and Trauma Outcome (PRESTO) Model and Pediatric Trauma Scoring Systems in a Middle-Income Country.

BACKGROUND: 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). METHODS: We included children (age < 15 years) admitted to a single trauma center in South Africa from December 2012 to January 2019. We excluded patients missing variables necessary for the PRESTO model-age, systolic blood pressure, pulse, oxygen saturation, neurologic status, and airway support. Trauma scores were assigned retrospectively. PRESTO's previously high-income country (HIC)-validated optimal threshold was compared to MIC-validated threshold using area under the receiver operating characteristic curves (AUROC). Prediction of in-hospital death using trauma scoring systems was compared using ROC analysis. RESULTS: Of 1160 injured children, 988 (85%) had complete data for calculation of PRESTO. Median age was 7 (IQR: 4, 11), and 67% were male. Mortality was 2% (n = 23). Mean predicted mortality was 0.5% (range 0-25.7%, AUROC 0.93). Using the HIC-validated threshold, PRESTO had a sensitivity of 26.1% and a specificity of 99.7%. The MIC threshold showed a sensitivity of 82.6% and specificity of 89.4%. The MIC threshold yielded superior discrimination (AUROC 0.86 [CI 0.78, 0.94]) compared to the previously established HIC threshold (0.63 [CI 0.54, 0.72], p < 0.0001). PRESTO showed superior prediction of in-hospital death compared to PTS and SIPA (all p < 0.01). CONCLUSION: PRESTO can be applied in MIC settings and discriminates between children at risk for in-hospital death following trauma. Further research should clarify optimal decision thresholds for quality improvement and benchmarking in LMIC settings.

Calibration and validation of the pediatric resuscitation and trauma outcome model among injured children in Rwanda.

BACKGROUND: Trauma is a leading cause of mortality in low- and middle-income countries. The Pediatric Resuscitation and Trauma Outcomes (PRESTO) model uses six low-tech variables available at point of care in resource-limited environments to predict in-hospital mortality of injured children. This model was never calibrated and validated in a low-income country. We aimed to calibrate the model's coefficients and compare its performance against the Revised Trauma Score (RTS) and Kampala Trauma Score (KTS) using data from a low-income country. STUDY DESIGN: Data from 2011 to 2015 in the prospectively-maintained Rwanda Injury Registry were reviewed after ethical approval was obtained. Patients were included for analysis if they were referred or admitted for traumatic injury, were younger than 15 years and if hospital outcomes were recorded. The variables in the PRESTO model include age, hypotension, heart rate, neurological status, oxygen saturation and airway intervention. The outcome of interest was in-hospital death. After calibration, Receiver-Operating-Characteristic curves were constructed to compare the area-under-curve (AUC) of PRESTO, RTS, and KTS with imputation of missing data. Comparisons of the relative AUC's were performed using Delong's test after bootstrapping in the full cohort and in a subset of patients <5 years-old. RESULTS: There were 113 in-hospital deaths out of 1695 included patients (6.7%). The AUC for the PRESTO model was 0.90 (95% CI [0.82-0.91]), higher than for RTS (0.77, 95% CI [0.80-0.97], p < 0.01) but not statistically different from KTS (0.89, 95% CI [0.72-0.82], p = 0.856). In the under-five cohort, the PRESTO model AUC was 0.84 (95% CI [0.75-0.92]), significantly higher than RTS (0.73 95% CI [0.64-0.81], p < 0.01) and KTS (0.58, 95% CI [0.50-0.66], p < 0.01). CONCLUSION: PRESTO appears to be the superior benchmarking tool for pediatric patients in a low- and middle-income country context. The PRESTO score outperforms the KTS in children <5 years of age. Further validation of the PRESTO model is needed from other low- and middle-income settings. LEVEL OF EVIDENCE: Level III: case-control (prognostic) study.

Towards Development of an Open Surgery Competency Assessment for Residents (OSCAR) Tool - A Systematic Review of the Literature and Delphi Consensus.

OBJECTIVE: Competency-based education has mandated accurate intra-operative assessment tools. We aimed to define consensus-based open surgical skills perceived by experts as critical for assessment. DESIGN: A mixed-method design was employed: systematic review and e-Delphi methodology. SETTING: The study was performed at McGill University-affiliated large tertiary academic centers in Montreal, Quebec, Canada. PARTICIPANTS: Per PRISMA guidelines, a peer-reviewed search strategy was employed. Studies published in English and those describing technical skill assessment of open abdominal surgery were included; subspecialty-specific skills, conference abstracts, academic memoirs were excluded. Most-cited skills were subjected to e-Delphi methodology to identify those deemed essential by experts, based a 3-point Likert scale. Eighteen McGill University-affiliated general surgeons, representing a variety of subspecialties of General Surgery, were invited to answer the questionnaire. RESULTS: Around 120 of 4285 references were retained for analysis. The 12 most cited skills included suturing, tissue and instrument handling, movement economy, instrument knowledge, knot tying, flow, knowledge of procedure, completion time, dissection technique, knowledge of anatomy and sterile technique; 6 of these achieved high or perfect scores and agreement after 2 rounds of survey: suturing, sterile technique, knot tying, knowledge of anatomy, knowledge of procedure, and tissue handling. Median standard deviation decreased (0.495 to 0.450) from first to second round, indicating improvement in consensus. CONCLUSION: These results will help develop and validate the OSCAR (objective structured clinical assessment rubric) assessment tool for immediate intra-operative feedback of open technical skills for surgical trainees.

Validation of the PRESTO score in injured children in a South-African quaternary trauma center.

INTRODUCTION: The Pediatric RESuscitation and Trauma Outcome (PRESTO) model was developed for standardized risk-adjustment in pediatric trauma and is adapted to low-resource settings. It includes easily-accessible demographic and physiologic variables that are available at point of care in virtually any setting. The purpose of this study was to evaluate the PRESTO model's ability to predict in-hospital mortality in a South African pediatric trauma unit by comparing it to the widely used Injury Severity Score (ISS). METHODS: Data prospectively collected between 2007 and 2017 in the Inkosi Albert Luthuli Central Hospital Trauma Registry were retrospectively reviewed. Injured children younger than 14 years were included if they were admitted to hospital or died as a result of their injury. We excluded patients with minor injuries who were treated and discharged home and patients with incomplete hospital disposition data. Receiver-Operating Characteristic (ROC) curves were constructed for PRESTO and ISS, and the areas under the curve (AUCs) were compared using Delong's test. The sensitivity and specificity of PRESTO were calculated at different prognostic threshold values identified through literature review. RESULTS: We identified 419 patients; 67 died in hospital (16%). The AUCs for PRESTO and ISS were 0.82 (95% confidence interval CI [0.76-0.87]) and 0.75 (CI [0.68-0.81]), respectively. This difference trended towards statistical significance (p = 0.07). Using the optimal threshold of 0.13 described in the original publication, PRESTO had a 97% sensitivity and 37% specificity, while a threshold of 0.50 yielded 90% sensitivity and 54% specificity. The mean predicted probability of in-hospital death among patients who died was 0.79. Using this value as a threshold yielded the 57% sensitivity and 85% specificity. CONCLUSION: This analysis has demonstrated the validity of the PRESTO model for in-hospital mortality prediction for pediatric trauma patients in the setting of a dedicated high-complexity trauma unit in a South African trauma referral center. LEVEL OF EVIDENCE: Level III: Case-control.

Determination of Visual Portfolio for Surgeons OverSeas Assessment of Surgical Needs Nigeria Study: Consensus Generation through an e-Delphi Process.

BACKGROUND: Surgery as a public health priority has received little attention until recently. There is a significant unmeasured and unmet burden of surgical illness in low- and middle-income countries (LMICs). Our aim was to generate a consensus among expert pediatric surgeons practicing in LMICs regarding the spectrum of pediatric surgical conditions that we should look out for in a community-based survey for Surgeons OverSeas Assessment of Surgical Needs Nigeria study. MATERIALS AND METHODS: The Delphi methodology was utilized to identify sets of variables from among a panel of experts. Each variable was scored on a 5-point Likert scale. The experts were provided with an anonymous summary of the results after the first round. A consensus was achieved after two rounds, defined by an improvement in the standard deviation (SD) of scores for a particular variable over that of the previous round. We invited 76 pediatric surgeons through e-mail across Africa but predominantly from Nigeria. RESULTS: Twenty-one pediatric surgeons gave consent to participate through return of mail. Thirteen (62%) answered the first round statements and 8 (38%) the second round. In general, the strength of agreement to all statements of the questionnaire improved between the first and second rounds. Overall consensus, as expressed by the decrease in the mean SD from 0.84 in the first round to 0.68 in the second round, also improved over time. The strength of consensus improved for 23 (74%) of the statements. The strength of consensus decreased for the remaining 8 (26%) of statements. Out of the 31 consensus-generating statements, 16 (51%) scored high agreement, 13 (42%) scored low agreement, and 2 (15%) scored perfect disagreement. CONCLUSION: We have successfully identified the pediatric surgical conditions to be included in any community survey of pediatric surgical need in an LMIC setting.

Incidence and prevalence of congenital anomalies in low- and middle-income countries: A systematic review.

BACKGROUND: In the absence of robust data from low- and middle-income countries (LMICs), most disease burden estimates and related resource allocation choices are based on historic Northern demographics. We hypothesize that significant discrepancies exist between directly reported LMIC data and surrogate high-income country (HIC) disease burden estimates of correctible congenital anomalies. METHODS: Nine online databases were searched for studies reporting incidence and prevalence data on surgically correctible congenital anomalies in LMICs between 2006 and 2017. Two independent reviewers screened titles and abstracts, with a third adjudicating discrepancies. Selected studies were reviewed and analyzed. RESULTS: Of 10,128 identified articles, 98 were extracted for full-text review, and 41 were included, representing 21 LMICs and 18 conditions. Study types included community surveys (34%), prospective (22%) and retrospective (17%) multi-site data, registries (12%), single-site data (12%), and systematic reviews (5%). Data collection periods were 1 to 10 years. The pooled epidemiologic data varied systematically from existing HIC literature, with the incidence of disease being generally lower in LMICs. CONCLUSIONS: Marked discrepancies exist between reported epidemiological data in LMICs and HIC literature, in part owing to varying quality of data collection in LMICs. Robust population-based surveys are needed to accurately estimate the burden of surgically correctable congenital anomalies in LMICs. LEVEL OF EVIDENCE: Level V, expert opinion without explicit critical appraisal.

A systematic review of capacity assessment tools in pediatric surgery: Global Assessment in Pediatric Surgery (GAPS) Phase I.

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.

Vacuum bell treatment of pectus excavatum: An early North American experience.

PURPOSE: 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. METHODS: 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). RESULTS: 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 usage >2 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. CONCLUSION: 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. TYPE OF STUDY: Treatment study; case series with no comparison group. LEVEL OF EVIDENCE: Level IV.

Factors contributing to successful trauma registry implementation in low- and middle-income countries: A systematic review.

BACKGROUND: Trauma registries (TR) provide invaluable data, informing resource allocation and quality improvement. The purpose of this systematic review was to identify factors promoting and inhibiting successful TR implementation in low- and middle-income countries (LMICs). METHODS: The protocol was registered a priori (CRD42017058586). With librarian oversight, a peer-reviewed search strategy was developed. Adhering to PRISMA guidelines, two independent reviewers performed first-screen and full-text screening. Studies describing implementation of a TR in LMICs or reviewed the experience of registry users/implementers were included. Extracted data, focusing on publication, institution, registry and data factors, was summarized using descriptive statistics and subjected to thematic qualitative analysis. RESULTS: Out of 3842 screened references, 40 articles were included for analysis. Most registries were paper-based, implemented in single publicly-funded institutions within LMICs, benefited from funding, and were run by untrained house-staff with other clinical responsibilities. Constituent variables, injury scoring, outcome assessment, and quality assurance practices were very diverse. Principal obstacles to successful implementation were lack of funding, significant missing data, and insufficient resources. CONCLUSIONS: This work may contribute to the planning of future efforts towards TR implementation in LMICs, where better injury data has the potential to alleviate the morbidity and mortality associated with trauma through advocacy and quality-improvement.

Outcomes after completion total gastrectomy for gastric remnant cancer: experience from a Canadian tertiary centre.

BACKGROUND: There is controversy about the safety and outcomes of completion total gastrectomy (CTG) for gastric adenocarcinoma. We compared a cohort of patients who underwent CTG for gastric remnant cancer (GRC) after partial gastrectomy for benign disease with patients who underwent primary total gastrectomy (PTG) for sporadic gastric cancer. METHODS: We retrospectively reviewed a single-institution, prospectively maintained clinical database of patients who had undergone gastrectomy from 2005 to 2016 for demographic, surgical, clinical and tumour pathology data, as well as postoperative, pathologic and oncologic outcomes including complications, length of stay, disease-free survival and overall survival. We used the χ2 and Wilcoxon rank-sum tests to compare groups and performed the Mantel-Cox log-rank test for Kaplan-Meier survival estimates. We compared the CTG group to all patients in the PTG group and to a 5:1 propensity-matched PTG cohort. RESULTS: We analyzed data for 64 patients (9 CTG, 55 PTG). The groups were equivalent at baseline and had similar operative, perioperative treatment and pathologic characteristics. After propensity matching, the reoperation rate for complications was higher after CTG than PTG (22% v. 0%, p = 0.03), but there was no significant difference in the overall complication rate or length of stay. At 5 years, there was no difference in disease-free survival (28% v. 58%, p = 0.4) or overall survival (33% v. 44%, p = 0.7). CONCLUSION: Our findings suggest that CTG for gastric adenocarcinoma can be undertaken safely a priori with no additional risk of recurrence or death compared to PTG for sporadic gastric cancer.

CONTEXTE: Les avis divergent en ce qui concerne l'innocuité et les résultats de la gastrectomie totale complémentaire (GTC) dans les cas d'adénocarcinome gastrique. Nous avons comparé une cohorte de patients soumis à la GTC pour cancer gastrique résiduel (CGR) après une gastrectomie partielle pour maladie bénigne à des patients ayant subi une gastrectomie totale primaire (GTP) pour cancer gastrique sporadique. MÉTHODES: Nous avons passé en revue rétrospectivement une base de données (maintenue de manière prospective) regroupant des patients soumis à une gastrectomie entre 2005 et 2016 dans un seul établissement; et nous avons recueilli les données démographiques, chirurgicales, cliniques et anatomopathologiques tumorales, de même que les résultats oncologiques, y compris complications, durée du séjour, survie sans maladie et survie globale. Nous avons utilisé les tests du χ2 et de Wilcoxon pour comparer les groupes et nous avons estimé la survie selon le méthode Kaplan-Meier à l'aide du test log-rank de Mantel-Cox. Nous avons comparé le groupe GTC à tous les patients du groupe GTP et à une cohorte assortie selon un score de propension 5:1. RÉSULTATS: Nous avons analysé les données de 64 patients (9 GTC, 55 GTP). Les groupes étaient équivalents au départ et présentaient des caractéristiques similaires pour ce qui est de la chirurgie, des soins périopératoires et des analyses anatomopathologiques. Suite à l'appariement par score de propension, le taux de réintervention pour complications a été plus élevé après la GTC qu'après la GTP (22 % c. 0 %, p = 0,03), mais on n'a noté aucune différence significative pour ce qui est du taux de complications global ou de la durée du séjour. Après 5 ans, il n'y avait pas de différence de survie sans maladie (28 % c. 58 %, p = 0,4) ou de survie globale (33 % c. 44 %, p = 0,7). CONCLUSION: Selon nos observations, a priori, la GTC peut être effectuée sans danger dans les cas d'adénocarcinome gastrique, sans risque additionnel de récurrence ou de décès, comparativement à la GTP pour cancer gastrique sporadique.

Out-of-Pocket and Catastrophic Expenses Incurred by Seeking Pediatric and Adult Surgical Care at a Public, Tertiary Care Centre in Uganda.

BACKGROUND: Surgical care is critical to establish effective healthcare systems in low- and middle-income countries, yet the unmet need for surgical conditions is as high as 65% in Ugandan children. Financial burden and geographical distance are common barriers to help-seeking in adult populations and are unmeasured in the pediatric population. We thus measured out-of-pocket (OOP) expenses and distance traveled for pediatric surgical care in a tertiary hospital in Mbarara, Uganda, as compared to adult surgical and pediatric medical patients. METHODS: Patients admitted to pediatric surgical (n = 20), pediatric medical (n = 18) and adult surgical (n = 18) wards were interviewed upon discharge over a period of 3 weeks. Patient and caregiver-reported expenses incurred for the present illness included prior/future care needed, and travel distance/cost. The prevalence of catastrophic expenses (≥10% of annual income) was calculated and spending patterns compared between wards. RESULTS: Thirty-five percent of pediatric medical patients, 45% of pediatric surgical patients and 55% of adult surgical patients incurred catastrophic expenses. Pediatric surgical patients paid more for their current treatment (p < 0.01)-specifically medications (p < 0.01) and tests (p < 0.01)-than pediatric medical patients, and comparable costs to adults. Adult patients paid more for treatment prior to the hospital (p = 0.04) and miscellaneous expenses (e.g., food while admitted) (p = 0.02). Patients in all wards traveled comparable distances. CONCLUSIONS: Seeking healthcare at a publicly funded hospital is financially catastrophic for almost half of patients. Out-of-stock supplies and broken equipment make surgical care particularly vulnerable to OOP expenses because analgesics, anaesthesia and preoperative imaging are prerequisites to care.

Gastrocutaneous fistulae in children - A systematic review and meta-analysis of epidemiology and treatment options.

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.
