Abstract
BACKGROUND Lung hypoplasia contributes to congenital diaphragmatic hernia (CDH) associated morbidity and mortality. Changes in lung wingless-type MMTV integration site family member (Wnt)-signalling and its downstream effector beta-catenin (CTNNB1), which acts as a transcription coactivator, exist in animal CDH models but are not well characterized in humans. We aim to identify changes to Wnt-signalling gene expression in human CDH lungs and hypothesize that pathway expression will be lower than controls. METHODS We identified 51 CDH cases and 10 non-CDH controls with archival formalin-fixed paraffin-embedded (FFPE) autopsy lung tissue from 2012 to 2022. 11 liveborn CDH cases and an additional two anterior diaphragmatic hernias were excluded from the study, leaving 38 CDH cases. Messenger ribonucleic acid (mRNA) expression of Wnt-signalling effectors WNT2B and CTNNB1 was determined for 19 CDH cases and 9 controls. A subset of CDH cases and controls lung sections were immunostained for β-catenin. Clinical variables were obtained from autopsy reports. RESULTS Median gestational age was 21 weeks. 81% (n = 31) of hernias were left-sided. 47% (n = 18) were posterolateral. Liver position was up in 81% (n = 31) of cases. Defect size was Type C or D in 58% (n = 22) of cases based on autopsy photos, and indeterminable in 42% (n = 16) of cases. WNT2B and CTNNB1 mRNA expression did not differ between CDH and non-CDH lungs. CDH lungs had fewer interstitial cells expressing β-catenin protein than non-CDH lungs (13.2% vs 42.4%; p = 0.006). CONCLUSION There appear to be differences in the abundance and/or localization of β-catenin proteins between CDH and non-CDH lungs. LEVEL OF EVIDENCE Level III. TYPE OF STUDY Case-Control Study.

High frequency jet ventilation for congenital diaphragmatic hernia. J Pediatr Surg 2023; 58:799-802. [PMID: 36788056 DOI: 10.1016/j.jpedsurg.2023.01.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Accepted: 01/03/2023] [Indexed: 01/22/2023]
Abstract
BACKGROUND The optimal role of high frequency jet ventilation (HFJV) in lung protective stabilization of congenital diaphragmatic hernia (CDH) remains uncertain. We aimed to describe our center's experience with HFJV as both a rescue (following failed stabilization with CMV) and primary ventilation mode in the management of CDH. METHODS Liveborn CDH patients treated from 2013 to 2021 in a single institution were reviewed. We compared 3 groups based on their primary and last ventilation mode prior to surgery: CMV (Group 1); HFJV (Group 2); and CMV/HFJV (Group 3). Outcomes included a composite primary outcome (≥1 of mortality, need for ECMO or need for supplemental O2 at discharge), total invasive ventilation days and development of pneumothorax. A descriptive analysis including univariate group comparisons was performed. Multivariate logistic regression models investigating the relationship between mode of ventilation and the primary outcome adjusted by potentially confounding covariates were constructed. RESULTS 56 patients (32 Group 1, 18 Group 2, 6 Group 3) were analyzed. Group 2 and 3 patients had more severe disease based on liver position, SNAP-II score, pulmonary hypertension severity, need for inotropic support, CDHSG defect size and need for patch repair. There were no group differences in survival, need for ECMO, or pneumothorax occurrence, although infants receiving HFJV required longer invasive ventilation and had a greater need for O2 at discharge. Multivariate logistic regression revealed no associations between mode of ventilation and outcome. CONCLUSIONS HFJV appears effective, both for CMV rescue and as a primary ventilation strategy in high risk CDH. LEVEL OF EVIDENCE Level IV.

Disparities in surgical health service delivery and outcomes for indigenous children. J Pediatr Surg 2023; 58:375-383. [PMID: 36241445 DOI: 10.1016/j.jpedsurg.2022.09.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Revised: 09/05/2022] [Accepted: 09/12/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND Evidence of health disparities for Indigenous children requiring surgical care is lacking. We present a systematic review of the literature examining possible disparities in surgical care and outcomes for pediatric patients of Indigenous ethnicity. DATA SOURCES PubMed, Cochrane, MEDLINE, gray literature. METHODS Literature review, using PubMed, Cochrane, MEDLINE, and gray literature was conducted to identify articles published more than 2010-2020 examining children's surgical health service delivery (epidemiology, access, operations provided) and outcomes for pediatric patients of Indigenous ethnicity compared with others. Extracted data included study design, setting, participant race/ethnicity, operations examined, and surgical outcomes. Article quality was assessed using the Newcastle-Ottawa Scales. RESULTS From 411 abstracts, 125 articles were reviewed and 33 included for data abstraction. These were cohort and cross-sectional studies investigating a wide range of patient populations and procedures across the United States, Canada, Australia, and New Zealand. Articles were organized naturally by theme into birth malformations (15 articles), trauma (6 articles), pediatric general surgery/appendicitis (5 articles), pediatric otolaryngology (6 articles), and renal transplant (1 article) surgery. Four articles also described access and resource utilization related to inpatient care. Notable disparities observed included apparent increased prevalence of gastroschisis, rates of traumatic fatality, non accidental injury, and self harm among North American Indigenous children. CONCLUSIONS Indigenous children appear to be vulnerable to a number of health and treatment outcome disparities related to conditions treated by surgeons. Surgeons are thus uniquely poised to act in identifying and eliminating Indigenous ethnicity-based pediatric health disparities.

Abstract
Neonates are highly susceptible to infections owing to their immature cellular and humoral immune functions, as well the need for invasive devices. There is a wide practice variation in the choice and duration of antimicrobial treatment, even for relatively common conditions in the NICU, attributed to the lack of evidence-based guidelines. Early decisive treatment with broad-spectrum antimicrobials is the preferred clinical choice for treating sick infants with possible bacterial infection. Prolonged antimicrobial exposure among infants without clear indications has been associated with adverse neonatal outcomes and increased drug resistance. Herein, we review and summarize the best practices from the existing literature regarding antimicrobial use in commonly encountered conditions in neonates.

Abstract
Gastroschisis (GS) is a full-thickness abdominal wall defect in which fetal intestine herniates alongside the umbilical cord into the intrauterine cavity, resulting in an intestinal injury of variable severity. An increased prevalence of gastroschisis has been observed across several continents and is a focus of epidemiologic study. Prenatal diagnosis of GS is common and allows for delivery planning and treatment in neonatal intensive care units (NICUs) by collaborative interdisciplinary teams (neonatology, neonatal nursing and pediatric surgery). Postnatal treatment focuses on closure of the defect, optimized nutrition, complication avoidance and a timely transition to enteral feeding. Babies born with complex GS are more vulnerable to complications, have longer and more resource intensive hospital stays and benefit from standardized care pathways provided by teams with expertise in managing infants with intestinal failure. This article will review the current state of knowledge related to the medical and surgical management and outcomes of gastroschisis with a special focus on the role of the neonatologist in supporting integrated team-based care.

Abstract
ABSTRACT Abdominal tuberculosis (TB) is rare in children and usually spread in the peritoneum or gastrointestinal tract. Symptoms tend to be vague and nonspecific, with no extra-abdominal involvement, presenting a challenge for clinicians and delayed diagnosis. Postnatally acquired abdominal TB is most commonly transmitted through inhalation or ingestion of respiratory droplets with Mycobacterium tuberculosis from the mother.Abdominal TB in infants is rare. We present a case of a 2-month-old infant presenting with an acute bowel obstruction secondary to abdominal TB acquired through contact with maternal TB mastitis. This unique case emphasizes the importance of considering abdominal TB in the differential for at-risk infants presenting with small bowel obstruction.

Abstract
Germ cell tumors in infants are most frequently extragonadal, benign, and amenable to surgical resection. An unusual feature of germ cell tumors is the potential coexistence of malignant with benign disease which makes it possible for patients with incompletely resected tumors to experience either a benign or malignant recurrence. A challenge to postoperative surveillance is the interpretation of serum alpha fetoprotein, a marker of malignancy, that is physiologically elevated during the first year of life. A rare subset of germ cell tumors occur in the retroperitoneum. Although the vast majority are benign, these tumors are often large and distort normal anatomy, and may demonstrate local invasiveness that increases risk of resection. The intent of these reports is to caution readers about these unusual features of germ cell tumors of infancy.

Abstract
OBJECTIVE: To develop an international Core Outcome Set (COS), a minimal collection of outcomes that should be measured and reported in all future clinical trials evaluating treatments of acute simple appendicitis in children. SUMMARY BACKGROUND DATA A previous systematic review identified 115 outcomes in 60 trials and systematic reviews evaluating treatments for children with appendicitis, suggesting the need for a COS. METHODS The development process consisted of four phases: (1) an updated systematic review identifying all previously reported outcomes, (2) a two-stage international Delphi study in which parents with their children and surgeons rated these outcomes for inclusion in the COS, (3) focus groups with young people to identify missing outcomes, and (4) international expert meetings to ratify the final COS. RESULTS The systematic review identified 129 outcomes which were mapped to 43 unique outcome terms for the Delphi survey. The first-round included 137 parents (eight countries) and 245 surgeons (10 countries), the second-round response rates were 61% and 85% respectively, with ten outcomes emerging with consensus. After two young peoples' focus groups, two additional outcomes were added to the final COS (12): mortality, bowel obstruction, intra-abdominal abscess, recurrent appendicitis, complicated appendicitis, return to baseline health, readmission, reoperation, unplanned appendectomy, adverse events related to treatment, major and minor complications. CONCLUSION An evidence-informed COS based on international consensus, including patients and parents has been developed. This COS is recommended for all future studies evaluating treatment of simple appendicitis in children, to reduce heterogeneity between studies and facilitate data synthesis and evidence-based decision-making.

Abstract
Identifying pulmonary nodules for resection that are small or are deep within the lung parenchyma is a frequently encountered challenge during video-assisted thoracoscopic surgery (VATS). Several image-guided localizing techniques have been described; however, there is limited literature on using these techniques in pediatric patients. We assessed the feasibility of using a commercially available ethylene-vinyl alcohol polymer (EVOH) as an alternative technique for lung nodule localization prior to VATS. We describe our experience of successful EVOH lung nodule localization in three pediatric patients with an oncologic history presenting with new lung nodules.

Abstract
Background In Canada, access to subspecialty surgical services for children imposes inconvenience and financial hardship on geographically remote families. The purpose of this study was to evaluate a recently implemented pediatric surgical telehealth pilot program from the family and provider perspectives. Methods Enabled by an existing telehealth infrastructure for pediatric subspecialty medicine and mental health, a pilot telehealth program for surgical consultation was established by a single surgeon in British Columbia. Following establishment of eligibility criteria, patients from remote communities requiring new consultation or clinical follow-up were offered a telehealth alternative. At the end of the encounter, both the parent and patient (if appropriate) provided feedback via a questionnaire. Provider satisfaction was also assessed via a questionnaire. We estimated costs avoided and analyzed data on pediatric surgery consultation wait time. Results Between September 2014 and November 2017, 80 patients were seen in 19 remote telehealth centres, 23 as new referrals and 57 in follow-up consultation. Among new referrals, the commonest diagnosis was chest wall deformity. The average travel distance avoided was 705 km, with an estimated direct cost avoidance of $585. Sixty-four families (80%) completed the questionnaire. Almost all (63 [98%]) indicated high overall satisfaction with the telehealth experience. Provider satisfaction was similarly high, in terms of both the technology user interface and clinical effectiveness. Overall pediatric surgical consultation wait times were unaffected. Conclusion Implementation of telehealth technology in a pediatric surgical practice offered high value to patients/families and, from the provider’s perspective, yielded an acceptable alternative to in-person assessment.

Abstract
Background Narrative data about the patient experience of surgery can help healthcare professionals and administrators better understand the needs of patients and their families as well as provide a foundation for improvement of procedures, processes and services. However, units often lack a methodological framework to analyse these data empirically and derive key areas for improvement. The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) is aimed at improving the quality of surgical care by collecting patient data and reporting risk-adjusted surgical outcomes for each participant hospital in the programme. Though qualitative data about patient experience are captured as part of the NSQIP database, to date no framework or methodology has been proposed, or reported on, to analyse these data for the purposes of quality improvement. The goal of this study was to demonstrate the feasibility of using content analysis to empirically derive key areas for quality improvement from a sample of 3601 narrative comments about paediatric surgery from patients and families at British Columbia Children’s Hospital. Study design Thematic content analysis conducted on a total of 3601 patient and family narratives received between 2011 and 2018. Results Overall satisfaction with care was high and experiences with healthcare providers at the hospital were positive. Areas for improvement were identified in the themes of health outcomes, communication and surgery timelines. Results informed follow-up interprofessional quality improvement initiatives. Conclusions Recording and analysing patient experience data as part of validated quality improvement programmes such as ACS NSQIP can provide valuable and actionable information to improve quality of care.

Abstract
BACKGROUND/PURPOSE Improvement opportunities exist in the accuracy and timeliness of the diagnosis of childhood appendicitis. The purpose of our study was to conduct a post-implementation audit of a diagnostic pathway for children with suspected appendicitis presenting to our pediatric emergency department. METHODS We adopted a diagnostic pathway that utilized a validated risk of appendicitis stratification tool (Alvarado Score) with protocolized use of abdominal ultrasound for moderate risk patients. We conducted a 10% convenience sample audit of pathway patients treated over the subsequent 18-month period. Outcome measures included false negative and positive rates, sensitivity, specificity, and overall pathway accuracy. RESULTS One hundred thirty-four pathway patients, of which 22 (16.4%) had appendicitis confirmed pathologically, were evaluated. The risk group distribution of patients was: low risk (29%), moderate risk (60%), and high risk (11%). The negative appendectomy rate was 4.4% (reduced from 14% pre-pathway), and the false negative (missed appendicitis) rate was 3.0%. No patients received CT scans. Pathway sensitivity was 81.8%% (95% CI 59.7% to 94.8%), specificity-92.9%% (95% CI 86.4%-96.9%), and overall accuracy-91.0% (95% CI 84.9%-95.3%). CONCLUSION Implementation of a diagnostic pathway achieved a high level of accuracy and reduced our institutional negative appendectomy rate by 67%. The audit identified additional pathway improvement opportunities. LEVELS OF EVIDENCE Level IV.

Abstract
Omphalocele is an abdominal wall defect involving the umbilical ring which results in visceral herniation of small and large intestine, liver, spleen and sometimes gonads. The covering of the herniated viscera by a fused membrane consisting of peritoneum, Wharton's jelly and amnion projects viscera from mechanical injury and exposure to chemical irritants in amniotic fluid. Omphalocele is usually diagnosed before birth, is variable in size, and is frequently associated with chromosomal and somatic anomalies, syndromes, and variable degrees of pulmonary hypoplasia which can be lethal. In this article we examine surgical closure options for omphaloceles ranging from early primary fascial repair for small omphaloceles to a staged repair, often facilitated by an amnion preserving silo, which may be necessary for giant omphaloceles that cannot be closed primarily. We also review some of the adjuncts to abdominal wall reconstruction including tissue expansion and mesh. Conservative management (paint and wait) of giant omphaloceles is described elsewhere.

Abstract
INTRODUCTION Enhanced Recovery After Surgery (ERAS) guidelines integrate evidence-based practices into multimodal care pathways designed to optimise patient recovery following surgery. The objective of this project is to create an ERAS protocol for neonatal abdominal surgery. The protocol will identify and attempt to bridge the gaps between current practices and best evidence. Our study is the first paediatric ERAS protocol endorsed by the International ERAS Society. METHODS A research team consisting of international clinical and family stakeholders as well as methodological experts have iteratively defined the scope of the protocol in addition to individual topic areas. A modified Delphi method was used to reach consensus. The second phase will include a series of knowledge syntheses involving a rapid review coupled with expert opinion. Potential protocol elements supported by synthesised evidence will be identified. The Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) system will be used to determine strength of recommendations and the quality of evidence. The third phase will involve creation of the protocol using a modified RAND/UCLA Appropriateness Method. Group consensus will be used to rate each element in relation to the quality of evidence supporting the recommendation and the appropriateness for guideline inclusion. This protocol will form the basis of a future implementation study. ETHICS AND DISSEMINATION This study has been registered with the ERAS Society. Human ethics approval (REB 18-0579) is in place to engage patient families within protocol development. This research is to be published in peer-reviewed journals and will form the care standard for neonatal intestinal surgery.

Abstract
Question A 10-year-old girl who was seen in my office last week with acute-onset abdominal pain and fever was referred to an emergency department, was diagnosed with appendicitis, and was treated conservatively with antibiotics, without surgery. Has the paradigm for treating appendicitis changed, and which is the preferred treatment of appendicitis in children: antibiotics or appendectomy?Answer For more than 100 years, surgical management was the principal treatment of acute appendicitis. Potential adverse events associated with appendectomy include bleeding, surgical site infection, and ileus, as well as stress for children and their parents. The option of treating appendicitis with antibiotics has been known for decades, which has led to consideration of antibiotics alone as a therapeutic alternative to surgery for uncomplicated appendicitis. While there is a reasonable body of evidence in support of this practice in adults, the accumulation of evidence of the safety and effectiveness of non-operative management in children is ongoing. Large studies are still needed, and those are being conducted at this time, with results expected in the next few years.

Abstract
INTRODUCTION Anthropometric measurements can be used to define pediatric malnutrition. Our study aims to: (1) characterize the preoperative nutritional status of children undergoing abdominal or thoracic surgery, and (2) describe the associations between WHO-defined acute (stunting) and chronic (wasting) undernutrition (Z-scores <-2) and obesity (BMI Z-scores >+2) with 30-day postoperative outcomes. METHODS We queried the Pediatric NSQIP Participant Use File and extracted data on patients' age 29days to 18years who underwent abdominal or thoracic procedures. Normalized anthropometric measures were calculated, including weight-for-height for <2years, BMI for ages ≥2years, and height for age. Logistic regression models were developed to assess nutritional outlier status as an independent predictor of postoperative outcome. RESULTS 23,714 children (88% ≥2y) were evaluated. 4272 (18%) were obese, while 2640 (11.1%) and 904 (3.8%) were stunted and wasted, respectively, after controlling for gender, ASA/procedure/wound classification, preoperative steroid use, need for preoperative nutritional support, and obese children had higher odds of SSIs (OR 1.29, 95% CI 1.1-1.5, p=0.001), while stunted children were at increased risk of any 30-day postoperative complication (OR 1.16, 95% CI 1.0-1.3, p=0.036). CONCLUSION Children who are stunted or obese are at increased risk of adverse outcome after abdominal or thoracic surgery. LEVEL OF EVIDENCE III.

[PMID: 29499843 DOI: 10.1016/j.jpedsurg.2018.02.013] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2018] [Accepted: 02/01/2018] [Indexed: 10/18/2022]
Abstract
BACKGROUND/PURPOSE Elimination of unnecessary practice variation through standardization creates opportunities for improved outcomes and cost-effectiveness. A quality improvement (QI) initiative at our institution used evidence and consensus to standardize management of gastroschisis (GS) from birth to discharge. METHODS An interdisciplinary team utilized best practice evidence and expert opinion to standardize GS care. Following stakeholder engagement and education, care standardization was implemented in September 2014. A comparative cohort study was conducted on consecutive patients treated before (n=33) and after (n=24) standardization. Demographic, treatment, and outcome measures were collected from a prospective GS registry. Direct costs were estimated, and protocol compliance was audited. RESULTS BW, GA, and bowel injury severity were comparable between groups. Key practice changes were: closure technique (pre-88% primary fascial, post-83% umbilical cord flap; p<0.001), closure location (pre-97% OR, post-67% NICU; p<0.001), and GA avoidance (pre-0%, post-48%; p<0.001). Median post-closure ventilation days were shorter (pre-4, post-1; p<0.001), and SSI rates trended lower (pre-21%, post-8%; p=0.3) in the post-implementation group with no differences in TPN days or LOS. No significant difference was seen in average per-patient costs: pre-$85,725 ($29,974-221,061), post-$76,329 ($14,205-176,856). CONCLUSION Care standardization for GS enables practice transformation, cost-effective outcome improvement, and supports an organizational culture dedicated to continuous improvement.

The value of patient registries in advancing pediatric surgical care. J Pediatr Surg 2018; 53:863-867.

Abstract
Pediatric surgeons treat a variety of conditions that are distinguished by their low occurrence rate, complexity, and need for integrated multidisciplinary care. Although randomized controlled trials (RCTs) are considered the gold standard for generating evidence to inform best practice, they are poorly suited to rare diseases based on the variability of illness severity, unpredictability in clinical course, and the impact limitations of studying a single intervention at a time. An alternative to RCTs for comparative effectiveness research for rare diseases in pediatric surgery is the patient registry, which collects detailed and condition-specific patient level data related to illness severity, treatment, and outcome, and allows a large, disease-specific database to be created for the dual purposes of collaborative research and quality improvement across participating sites. This review discusses the various functions of a patient registry in fulfilling its mandate of evidence-based practice and outcome improvement using examples from a variety of existing pediatric surgical registries. The value proposition of patient registries as sources of knowledge, facilitators of practice standardization, and enablers of continuous quality improvement is discussed.

Abstract
Gastroschisis is the commonest developmental defect of the anterior abdominal wall in both developed and developing countries. The past 30 years have seen transformational improvements in outcome due to advances in neonatal intensive care and enhanced integration between the disciplines of maternal fetal medicine, neonatology and pediatric surgery. A review of gastroschisis, which emphasizes its epidemiology, multidisciplinary care strategies and contemporary outcomes is timely. Areas covered: This review discusses the current state of knowledge related to prevalence and causation, and postulated embryopathologic mechanisms contributing to the development of gastroschisis. Using relevant, current literature with an emphasis on high level evidence where it exists, we review modern techniques of prenatal diagnosis, pre and postnatal risk stratification, preferred timing and method of delivery, options for abdominal wall closure, nutritional management, and short and long term clinical and neurodevelopmental follow-up. Expert commentary: This section explores controversies in contemporary management which contribute to practice and cost variation and discusses the benefits of novel nutritional therapies and care standardization that target unnecessary practice variation and improve overall cost-effectiveness of gastroschisis care. The commentary concludes with a review of fertile areas of gastroschisis research, which represent opportunities for knowledge synthesis and further outcome improvement.

Abstract
OBJECTIVE WHO uses anthropometric classification scheme of childhood acute and chronic malnutrition based on low body mass index (BMI) ('wasting') and height for age ('stunting'), respectively. The goal of this study was to describe a novel two-axis nutritional classification scheme to (1) characterise nutritional profiles in children undergoing abdominal surgery and (2) characterise relationships between preoperative nutritional status and postoperative morbidity. DESIGN This was a retrospective observational cohort study. SETTING The setting was 50 hospitals caring for children in North America that participated in the American College of Surgeons National Surgical Quality Improvement Program Paediatric from 2011 to 2013. PARTICIPANTS Children >28 days who underwent major abdominal operations were identified. INTERVENTIONS/MAIN PREDICTOR The cohort of children was divided into five nutritional profile groups based on both BMI and height for age Z-scores: (1) underweight/short, (2) underweight/tall, (3) overweight/short, (4) overweight/tall and (5) non-outliers (controls). MAIN OUTCOME MEASURES Multiple variable logistic regressions were used to quantify the association between 30-day morbidity and nutritional profile groups while adjusting for procedure case mix, age and American Society of Anaesthesiologists class. RESULTS A total of 39 520 cases distributed as follows: underweight/short (656, 2.2%); underweight/tall (252, 0.8%); overweight/short (733, 2.4%) and overweight/tall (1534, 5.1%). Regression analyses revealed increased adjusted odds of composite morbidity (35%) and reintervention events (75%) in the underweight/short group, while overweight/short patients had increased adjusted odds of composite morbidity and healthcare-associated infections (43%), and reintervention events (79%) compared with controls. CONCLUSION Stratification of preoperative nutritional status using a scheme incorporating both BMI and height for age is feasible. Further research is needed to validate this nutritional risk classification scheme for other surgical procedures in children.

Abstract
OBJECTIVE To examine the effectiveness and meaningful use of paediatric surgical safety checklists (SSCs) and their implementation strategies through a systematic review with narrative synthesis. SUMMARY BACKGROUND DATA Since the launch of the WHO SSC, checklists have been integrated into surgical systems worldwide. Information is sparse on how SSCs have been integrated into the paediatric surgical environment. METHODS A broad search strategy was created using Pubmed, Embase, CINAHL, Cochrane Central, Web of Science, Science Citation Index and Conference Proceedings Citation Index. Abstracts and full texts were screened independently, in duplicate for inclusion. Extracted study characteristic and outcomes generated themes explored through subgroup analyses and idea webbing. RESULTS 1826 of 1921 studies were excluded after title and abstract review (kappa 0.77) and 47 after full-text review (kappa 0.86). 20 studies were of sufficient quality for narrative synthesis. Clinical outcomes were not affected by SSC introduction in studies without implementation strategies. A comprehensive SSC implementation strategy in developing countries demonstrated improved outcomes in high-risk surgeries. Narrative synthesis suggests that meaningful compliance is inconsistently measured and rarely achieved. Strategies involving feedback improved compliance. Stakeholder-developed implementation strategies, including team-based education, achieved greater acceptance. Three studies suggest that parental involvement in the SSC is valued by parents, nurses and physicians and may improve patient safety. CONCLUSIONS A SSC implementation strategy focused on paediatric patients and their families can achieve high acceptability and good compliance. SSCs' role in improving measures of paediatric surgical outcome is not well established, but they may be effective when used within a comprehensive implementation strategy especially for high-risk patients in low-resource settings.

Abstract
Among congenital malformations, congenital diaphragmatic hernia (CDH) is distinguished by its relatively low occurrence rate, need for resource intensive, integrated multidisciplinary care, and widespread variation in practice and outcome. Although randomized controlled trials (RCTs) are considered the gold standard for generating evidence, they are poorly suited to the study of a condition like CDH due to challenges in illness severity adjustment, unpredictability in clinical course and the impact limitations of studying a single intervention at a time. An alternative to RCTs for comparative effectiveness research for CDH is the patient registry, which aggregates multi-institutional condition-specific patient level data into a large CDH-specific database for the dual purposes of collaborative research and quality improvement across participating sites. This article discusses patient registries from the perspective of structure, data collection and management, and privacy protection that guide the use of registry data to support collaborative, multidisciplinary research. Two CDH-specific registries are described as illustrative examples of the "value proposition" of registries in improving the evidence basis for best practices for CDH.

Abstract
Closure of a giant omphalocele can be challenging. Preservation of the amnion in staged closure is not commonly practiced. Here, we describe 2 cases of giant omphalocele treated with a modified amnion preservation, staged closure technique. This paper demonstrates the feasibility and safety of this technique, and the versatility of amnion to adapt to an escharization strategy if closure is not achievable.

Abstract
BACKGROUND There is ample evidence that avoidable harm occurs in patients, including children, who undergo surgical procedures. Among a number of harm mitigation strategies, the use of surgical safety checklists (SSC) is now a required organizational practice for accreditation in all North American hospitals. Although much has been written about the effects of SSC on outcomes of adult surgical patients, there is a paucity of literature on the use and role of the SSC as an enabler of safe surgery for children. METHODS The Pediatric Surgical Chiefs of Canada (PSCC) advocates on behalf of all Canadian children undergoing surgical procedures. We undertook a survey of the use of SSC in Canadian children's hospitals to understand the variability of implementation of the SSC and understand its role as both a measure and driver of patient safety and to make specific recommendations (based on survey results and evidence) for standardized use of the SSC in Canadian children's hospitals. RESULTS Survey responses were received from all 15 children's hospitals and demonstrated significant variability in how the checklist is executed, how compliance is measured and reported, and whether or not use of the checklist resulted in specific instances of error prevention over a 12-month observation period. There was near unanimous agreement that use of the SSC contributed positively to the safety culture of the operating room. CONCLUSION Based on the survey results, the PSCC have made 5 recommendations regarding the use of the SSC in Canadian children's hospitals.

Abstract
The Canadian Pediatric Surgery Network (CAPSNet) has been collecting population-based data regarding congenital diaphragmatic hernia (CDH) across its 17 perinatal sites since 2005. With >500 infants registered to date, CAPSNet has addressed many critical knowledge gaps pertaining to CDH care. Most importantly, it has identified variability in both CDH practice and outcome across Canada. Using the successful Evidence-based Practice for Improving Quality (EPIQ) method, CAPSNet is undertaking a national, multidisciplinary effort to standardize best practices for CDH, from prenatal diagnosis to hospital discharge, based on the best available evidence. The present article outlines the value of clinical research networks and the process CAPSNet will undertake to produce national consensus guidelines for CDH care.

Abstract
OBJECTIVES Gastroschisis is a serious birth defect of the abdominal wall that is associated with mortality and significant morbidity. Our understanding of the factors causing this defect is limited. The objective of this paper is to describe the geographic variation in incidence of gastroschisis and characterize the spatial pattern of all gastroschisis cases in Canada between 2006 and 2011. Specifically, we aimed to ascertain the differences in spatial patterns between geographic regions and identify significant clusters and their location. METHODS The study population included 641 gastroschisis cases from the Canadian Pediatric Surgery Network (CAPSNet) database, a population-based dataset of all gastroschisis cases in Canada. Cases were geocoded based on maternal residence. Using Statistics Canada live-birth data as a denominator, the total prevalence of gastroschisis was calculated at the provincial/territorial levels. Random effects logistic models were used to estimate the rates of gastroschisis in each census division. These rates were then mapped using ArcGIS. Cluster detection was performed using Local Indicators of Spatial Association (LISA). RESULTS There is significant spatial heterogeneity of the rate of gastroschisis across Canada at both the provincial/territorial and census-division level. The Yukon, Northwest Territories and Prince Edward Island have higher overall rates of gastroschisis relative to other provinces/territories. Several census divisions in Alberta, Manitoba, Saskatchewan, Ontario, Northwest Territories and British Columbia demonstrated case "clusters", i.e., focally higher rates in discrete areas relative to surrounding areas. CONCLUSIONS There is clear evidence of spatial variation in the rates of gastroschisis across Canada. Future research should explore the role of area-based variables in these patterns to improve our understanding of the etiology of gastroschisis.

Abstract
BACKGROUND Nonoperative management of hemodynamically stable children with Solid Organ Injury (SOI) has become standard of care. The aim of this study is to identify differences in management of children with SOI treated at Adult Trauma Centers (ATC) versus Pediatric Trauma Centers (PTC). We hypothesized that patients treated at ATC would undergo more procedures than PTC. METHODS Patients younger than 18 years old with isolated SOI (spleen, liver, kidney) who were treated at level I-II ATC or PTC were identified from the 2011-2012 National Trauma Data Bank. The primary outcome measure was the incidence of operative management. Data was analyzed using multivariate logistic regression analysis. Procedures were defined as surgery or transarterial embolization (TAE). RESULTS 6799 children with SOI (spleen: 2375, liver: 2867, kidney: 1557) were included. Spleen surgery was performed more frequently at ATC than PTC {101 (7.7%) vs. 52 (4.9%); P=0.007}. After adjusting for potential confounders (grade of injury, age, gender and injury severity score), admission at ATC was associated with higher odds of splenic surgery (OR: 1.5, 95% CI: 1.02-2.25; p=0.03). 11 and 8 children underwent kidney and liver operations respectively. TAE was performed in 17 patients with splenic, 34 with liver and 14 with kidney trauma. There was no practice variation between ATC and PTC regarding kidney and liver operations or TAE incidence. CONCLUSIONS Operative management for SOI was more often performed at ATC. The presence of significant disparity in the management of children with splenic injuries justifies efforts to use these surgeries as a reported national quality indicator for trauma programs.

Abstract
The Canadian Pediatric Surgery Network (CAPSNet) was created in 2005 by a geographically representative, multidisciplinary group of clinicians and researchers with the intent of establishing a national research registry for gastroschisis (GS) and congenital diaphragmatic hernia (CDH). Since then, CAPSNet has used this registry and its 16-center network to make contributions to the knowledge base informing best practices for GS and CDH care. More recently, CAPSNet has expanded its focus to include quality assurance and improvement at each of its sites, by issuing a benchmarked outcomes "report card" with its annual report. Finally, a major objective of CAPSNet has been to establish and adopt standardized, evidence-based practice guidelines for GS and CDH across all Canadian perinatal centers.

Abstract
OBJECTIVE The purpose of this study was to determine the influence of planned mode and planned timing of delivery on neonatal outcomes in infants with gastroschisis. STUDY DESIGN Data from the Canadian Pediatric Surgery Network cohort were used to identify 519 fetuses with isolated gastroschisis who were delivered at all tertiary-level perinatal centers in Canada from 2005-2013 (n = 16). Neonatal outcomes (including length of stay, duration of total parenteral nutrition, and a composite of perinatal death or prolonged exclusive total parenteral nutrition) were compared according to the 32-week gestation planned mode and timing of delivery with the use of the multivariable quantile and logistic regression. RESULTS Planned induction of labor was not associated with decreased length of stay (adjusted median difference, -2.6 days; 95% confidence interval [CI], -9.9 to 4.8), total parenteral nutrition duration (adjusted median difference, -0.2 days; 95% CI, -6.4 to 6.0), or risk of the composite adverse outcome (relative risk, 1.7; 95% CI, 0.1-3.2) compared with planned vaginal delivery after spontaneous onset of labor. Planned delivery at 36-37 weeks' gestation was not associated with decreased length of stay (adjusted median difference, 5.9 days; 95% CI, -5.7 to 17.5), total parenteral nutrition duration (adjusted median difference, 3.2 days; 95% CI, -7.9 to 14.3), or risk of composite outcome (relative risk, 2.3; 95% CI, 0.8-5.4) compared with planned delivery at ≥38 weeks' gestation. CONCLUSION Infants with gastroschisis who were delivered after planned induction or planned delivery at 36-37 weeks' gestation did not have significantly better neonatal outcomes than planned vaginal delivery after spontaneous onset of labor and planned delivery at ≥38 weeks' gestation.

Abstract
Innovation in surgical techniques, technology, and care processes are essential for improving the care and outcomes of surgical patients, including children. The time and cost associated with surgical innovation can be significant, and unless it leads to improvements in outcome at equivalent or lower costs, it adds little or no value from the perspective of the patients, and decreases the overall resources available to our already financially constrained healthcare system. The emergence of a safety and quality mandate in surgery, and the development of the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) allow needs-based surgical care innovation which leads to value-based improvement in care. In addition to general and procedure-specific clinical outcomes, surgeons should consider the measurement of quality from the patients' perspective. To this end, the integration of validated Patient Reported Outcome Measures (PROMs) into actionable, benchmarked institutional outcomes reporting has the potential to facilitate quality improvement in process, treatment and technology that optimizes value for our patients and health system.

Abstract
Gastroschisis (GS) is a structural defect of the anterior abdominal wall, usually diagnosed antenatally, that occurs with a frequency of approximately 4 per 10,000 pregnancies. Babies born with GS require neonatal intensive care and surgical management of the abdominal wall defect soon after birth. Although contemporary survival rates for GS are over 90%, these babies are at risk for significant morbidity, and require 4 to 6 weeks of costly, resource-intensive care in specialized neonatal units. Much consideration has been given to how best to treat the abdominal wall defect of GS. The traditional approach, necessitated by a need to establish enteral feeding as quickly as possible, consists of early postnatal visceral reduction and sutured abdominal closure. Advances in neonatal nutritional support have enabled the development of surgical approaches, which permit gradual visceral reduction and delayed abdominal closure. In cases where early visceral reduction cannot be achieved, delayed closure enabled by the initial placement of a prosthetic silo has been a live-saving alternative. The development of preformed silos has simplified their use and led to an interest in treating all cases with a delayed closure philosophy. Most recently, a sutureless technique of abdominal closure has been reported, which has the benefit of avoiding general anesthesia and offers other outcome improvements over sutured closure of the defect. The debate over primary closure versus silo placement and delayed closure continues to receive much attention. The goal of this article is to review historical aspects of gastroschisis closure, and then focus on current surgical techniques, including the innovative sutureless closure, with an analysis of the comparative clinical effectiveness of these approaches to treatment of the abdominal wall defect in GS.

Abstract
PURPOSE The purpose of this study was to compare RCDH to LCDH from the perspective of prenatal diagnosis, illness severity, treatment, and outcome. METHODS A retrospective study of all cases of CDH registered in the Canadian Pediatric Surgery Network (CAPSNet) database from 2005 to 2013 was conducted. Side of defect comparisons were made by prenatal diagnostic features, birth demographic data, intensity of medical treatment, timing and type of surgery, and outcomes. Outcomes prediction with logistic regression modeling using side of defect as an exploratory covariate was performed. RESULTS The study cohort included 498 patients, of which 84 (17%) cases had RCDH. Prenatal diagnosis was more commonly made for LCDH. No difference existed in perinatal risk factors (GA, illness severity (SNAP-II) score, associated anomalies), preoperative treatment intensity (use of vasodilators, inotropes), timing of surgery, ventilation days, need for ECMO, LOS, and overall survival. Significant differences between RCDH and LCDH were detected for patch repair rate (48.2% vs. 30.6%; p=0.036) and recurrence (4.1% vs. 0.6%; p=0.038). Stepwise regression modeling identified side of hernia as independently predictive of need for patch. CONCLUSIONS Overall, little difference exists between RCDH and LCDH in terms of prognostic factors and outcomes.

Abstract
BACKGROUND While fascial closure is traditionally used in gastroschisis (GS), flap closure (skin or umbilical cord) has gained popularity. We evaluated early outcomes and complications of the two techniques. METHODS A national, population-based gastroschisis data registry was analyzed from 2005 to 2011. We compared fascial to flap closures and stratified patients into low or high-risk groups using the Gastroschisis Prognostic Score (GPS), a validated marker of post-natal bowel injury. Demographic and outcome data, including length of stay, complications, and markers of resource utilization were analyzed using Fisher's exact and Student's t-tests for categorical and continuous variables, respectively (p<0.05 significant). RESULTS The analyzed dataset included 436 fascial closures (344 [78.8%] low-risk, 92 high-risk) and 129 flap closures (112 [86.7%] low-risk, 17 high-risk; p=0.06). Demographics and birth weight did not differ between groups. In patients with low GPS, flap closure demonstrated significant decreases in resource utilization and failure of closure, without differences in complication rates. Analysis of high-risk patients revealed no statistically significant differences in outcome. CONCLUSION Flap closure was not associated with an increase in patient morbidity and seemed suitable as a definitive closure method for gastroschisis patients irrespective of disease severity. Furthermore, flap closure reduced several markers of resource utilization in patients with low-risk disease.

BACKGROUND Little is known about the factors influencing surgical practice variation in newborns with gastroschisis. The purpose of this study was to correlate prognostic variables with the intended and actual abdominal closure technique and assess related outcomes. METHODS GS cases were abstracted from a national database. Variables evaluated included GA, BW, bowel injury severity (GPS), neonatal illness severity (SNAP-II), inborn status, center volume and training status, and admission time. Evaluated outcomes by closure method included duration of TPN, LOS, and complications. Descriptive, univariate and multivariable regression analyses were conducted. RESULTS The cohort consisted of 679 patients. A total of 372 (55%) underwent attempted PR, of which 300 (81%) were successful, while 307 (45%) had a silo placed intentionally. Patients undergoing attempted PR were more likely to be inborn, have daytime admissions, and higher SNAP-II scores. Successful PR was predicted by low risk GPS and high volume center. With the exception of higher rates of SSI in the planned silo group, outcomes in the successful PR and planned silo groups were comparable. CONCLUSION Practice variation related to type of closure is predicted by situational and institutional factors (outborn, nighttime admission, and center volume), while outcome variation is attributable to patient factors rather than practice variation.

ACS national surgical quality improvement program: targeting quality improvement in Canadian pediatric surgery. J Pediatr Surg 2014; 49:682-7. [PMID: 24851748 DOI: 10.1016/j.jpedsurg.2014.02.047] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2014] [Accepted: 02/13/2014] [Indexed: 11/28/2022]
Abstract
PURPOSE The pediatric NSQIP program is in the early stages of facilitated surgical quality improvement for children. The objective of this study is to describe the initial experience of the first Canadian Children's Hospital participant in this program. METHOD Randomly sampled surgical cases from the "included" case list were abstracted into the ACS-NSQIP database. These surgical procedure-specific data incorporate patient risk factors, intraoperative details, and 30 day outcomes to generate annual reports which provide hierarchical ranking of participant hospitals according to their risk-adjusted outcomes. RESULTS Our first risk-adjusted report identified local improvement opportunities based on our rates of surgical site infection (SSI) and urinary tract infection (UTI). We developed and implemented an engagement strategy for our stakeholders, performed literature reviews to identify practice variation, and conducted case control studies to understand local risk factors for our SSI/UTI occurrences. We have begun quality improvement activities targeting reduction in rates of SSI and UTI with our general surgery division and ward nurses, respectively. CONCLUSIONS The NSQIP pediatric program provides high quality outcome data that can be used in support of quality improvement. This process requires multidisciplinary teamwork, systematic stakeholder engagement, clinical research methods and process improvement through engagement and culture change.

Surgical site infections in infants admitted to the neonatal intensive care unit. J Pediatr Surg 2014; 49:381-4. [PMID: 24650461 PMCID: PMC5756080 DOI: 10.1016/j.jpedsurg.2013.08.001] [Citation(s) in RCA: 42] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2013] [Revised: 07/31/2013] [Accepted: 08/02/2013] [Indexed: 01/30/2023]
Abstract
BACKGROUND Surgical interventions are common in infants admitted to the neonatal intensive care unit (NICU). Despite our awareness of the broad impact of surgical site infection (SSI), there are little data in neonates. Our objective was to determine the rate and clinical impact of SSI in infants admitted to the NICU. METHODS Provincial population-based study of infants admitted to a tertiary care NICU. SSI, explicitly defined, was included if it occurred within 30 days of a skin/mucosal-breaking surgical intervention. RESULTS Among 724 infants who underwent 1039 surgical interventions very low birth weight (VLBW) infants were over-represented. The overall SSI rate was 4.3 per 100 interventions [CI 95% 3.2 to 5.7], up to 19 per 100 dirty interventions (wound class 4) [CI 95% 4.0 to 46]. Rates were higher in infants following gastroschisis closure (13 per 100 infants [CI 95% 5.8 to 24]), whereas they were generally low following a ligation of a ductus arteriosus. Infants with SSI required longer hospitalization after adjusting for co-morbidities (p<0.001). CONCLUSIONS Data from this relatively large contemporary study suggest that SSI rates in the NICU setting are more comparable to the pediatric age group. However, VLBW infants and those undergoing gastroschisis closure represent high risk groups.

Use of safety scalpels and other safety practices to reduce sharps injury in the operating room: what is the evidence? Can J Surg 2013; 56:263-9.

Abstract
BACKGROUND The occupational hazard associated with percutaneous injury in the operating room (OR) has encouraged harm reduction through behaviour change and the use of safety-engineered surgical sharps. Some Canadian regulatory agencies have mandated the use of "safety scalpels." Our primary objective was to determine whether safety scalpels reduce the risk of percutaneous injury in the OR, while a secondary objective was to evaluate risk reduction associated with other safety practices. METHODS We used evidence review methods described by the International Liaison Committee on Resuscitation and conducted a systematic, English-language search of Ovid, MEDLINE and EMBASE using the following search terms: "safety-engineered scalpel," "mistake proofing device," "retractable/removable blade/scalpel," "pass tray," "hands free passing," "neutral zone," "sharpless surgery," "double/cutproof gloving" and "blunt suture needles." Included articles were scored according to level of evidence; quality; and whether they were supportive, opposed or neutral to the study question(s). RESULTS Of 72 included citations, none was supportive of the use of safety scalpels. There was high-level/quality evidence (Cochrane reviews) in support of risk reduction through double-gloving and use of blunt suture needles, with additional evidence supporting a pass tray/neutral zone for sharps handling (4 of 5 articles supportive) and use of suturing adjuncts (1 article supportive). CONCLUSION There is insufficient evidence to support regulated use of safety scalpels. Injury-reduction strategies should emphasize proven methods, including double-gloving, blunt suture needles and use of hands-free sharps transfer.

Management of the base of the appendix in pediatric laparoscopic appendectomy: clip, ligate, or staple? Surg Technol Int 2013; 23:81-83.

Abstract
Options for intracorporeal appendiceal stump closure span a variety of techniques including ligation using intra-corporeal knots, extra-corporeal knots, or an endo-loop (EL), closure with endoscopic clips (EC), or endoscopic stapled (ES) closure. The guiding principles are the need for secure, inert closure of the appendiceal base without injury to the appendiceal stump or cecum, with minimal risks of complication attributable to the closure technique. Safety and complication rates, as well as cost data, should guide the techniques used for pediatric laparoscopic appendectomy. Based on the literature available there is not a clear answer as to the best method for closing the appendiceal stump in pediatric patients, with each of the methods described providing safe closure. Many institutions and surgeons may favor a selective approach, with choice of closure determined by the condition of the appendix at laparoscopy.

Abstract
PURPOSE Little is known about liveborn CDH patients who die without surgery. We audited a national CDH cohort to determine whether these patients were different from patients who received CDH repair. METHODS A national CDH database was analyzed (2005-2009). After excluding infants with severe physiologic instability and genetic/congenital malformations, a potential surgical candidate (PSC) subgroup was identified. PSCs were compared to the operative group (OG) and the operative non-survivor (ONS) subgroup. Standard statistical analyses were performed. RESULTS Of 275 liveborns, 35 (13%) died without surgery. The PSC subgroup (n=11) had a median survival of 10 days (range: 3-18). Ten of 11 PSC infants were treated in ECMO centers, with 4 receiving ECMO. No differences in BW, GA, and rates of minor malformation were observed between PSC and OG patients. While neonatal illness severity (SNAP-II) predicted overall mortality, SNAP-II scores were similar between PSC and ONS groups (34 vs. 29; p=0.431). Furthermore, greater than 80% of infants with SNAP-II scores between 30 and 39 survived in the OG cohort. CONCLUSION Our analysis demonstrated that PSCs were similar to infants offered surgery based on illness severity and the presence of congenital malformations. We suggest that criteria for surgical ineligibility be developed to standardize the selection of surgical candidates.

Effect of timing of enteral feeding on outcome in gastroschisis. J Pediatr Surg 2013; 48:971-6. [PMID: 23701769 DOI: 10.1016/j.jpedsurg.2013.02.014] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2013] [Accepted: 02/03/2013] [Indexed: 10/26/2022]
Abstract
BACKGROUND Timely initiation of enteral nutrition is pivotal to outcome optimization in gastroschisis (GS). The purpose of our study was to analyze the effect of timing of first feeds on outcome. METHOD GS cases accrued between May 2005 and August 2011 were abstracted from a national database. Risk variables evaluated included GA, illness severity, bowel injury severity, and post-closure days to first feed (DTF). The outcomes analyzed included duration of TPN, LOS, and infectious complications. Descriptive, univariate, and multivariate regression analyses were conducted. RESULTS The study cohort comprised 570 cases (16% with "high risk" bowel injury). Group distribution by DTF was: 0-7 days (12%), 8-14 days (44%), 15-21 days (26%), and >21 days (17%), with a mean DTF of 17 ± 15 days. Mean durations of TPN and LOS were 44 ± 56 and 112 ± 71 days, respectively. DTF subgroups were comparable, except for a greater proportion of "high risk bowel injury" in DTF>21 days. Initiation of feeds between 8 and 21 days was associated with fewer TPN days and reduced LOS. Multivariate analyses revealed that TPN duration, LOS, and infectious complications were independently predicted by DTF. CONCLUSIONS Post-closure DTF predicts outcome in GS, with best outcomes observed when feeds are started 7 days post-closure.

The gastroschisis prognostic score: reliable outcome prediction in gastroschisis. J Pediatr Surg 2012; 47:1111-7.

Abstract
BACKGROUND/PURPOSE Disease-specific outcome predictors are required for gastroschisis. We derived and validated a gastroschisis prognostic score (GPS) based on bowel appearance after birth. METHODS Visual scoring of bowel matting, necrosis, atresia, and perforation generated a novel gastroschisis bowel injury score recorded in a national database. Reweighting of score components by regression analysis led to assessments of model calibration and goodness of fit. The GPS was validated in subsequent cases. RESULTS Records from 225 infants were used for model derivation. Only intestinal necrosis independently predicted mortality by regression analysis (odds ratio, 11.5; 95% confidence interval, 4.2-31.4). Model recalibration identified that a GPS of 4 or more predicted mortality in 75% of nonsurvivors and 99% of survivors (P = .0001). A GPS of 2 or more demonstrated significantly worse survival outcomes compared with scores of 0 or 1 (length of stay: P = .011, days to first enteral feed: P = .013, days on total parenteral nutrition: P = .006). Model validation with 184 new patients yielded continued high-quality discrimination of outcomes. The GPS demonstrated "near-perfect" interobserver reliability between 2 surgeons (κ ≥ 0.86). CONCLUSIONS The GPS allows the accurate and reliable identification of high-risk groups for mortality and morbidity based on bowel appearance at birth. This information can drive discussions regarding family counseling, resource allocation, and new therapies for these patients.

Chylothorax after congenital diaphragmatic hernia repair: a population-based study. J Pediatr Surg 2012; 47:842-6. [PMID: 22595558 DOI: 10.1016/j.jpedsurg.2012.01.031] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2011] [Accepted: 01/26/2012] [Indexed: 02/07/2023]
Abstract
PURPOSE Chylothorax is a recognized complication of congenital diaphragmatic hernia (CDH) repair. Our aims were to describe the frequency and outcomes of chylothorax and to seek predictors of chylothorax occurrence within a population-based CDH cohort. METHODS Records for patients with CDH born between 2006 and 2010 were abstracted from a national database and were compared according to presence/absence of postrepair chylothorax. Univariate, and where appropriate, multivariate analyses were performed for group comparisons and chylothorax outcome prediction. RESULTS Of 243 newborns with CDH surviving to repair, 11 (4.5%) developed a chylothorax. All were managed nonoperatively. Factors predictive of chylothorax outcome on multivariate analysis included need for preoperative transfusion (odds ratio, 13.2; 95% confidence interval, 2.1-83.7; P = .006) and preoperative high-frequency oscillatory ventilation (odds ratio, 7.1; 95% confidence interval, 1.6-31.2; P = .01). Preoperative vasopressor use was significant on univariate analysis only. The groups were comparable for survival, length of stay, and duration of ventilation, but chylothorax patients had prolonged total parenteral nutrition (53 vs 21 days, P = .006) and more central line days (46 vs 24 days, P = .03). CONCLUSIONS Our data suggest that severity of preoperative cardiopulmonary derangement and not anatomical or technical factors predicts chylothorax occurrence after CDH repair.

Abstract
BACKGROUND Little is known about associated anomalies in fetuses with gastroschisis (GS) who experience an "atypical perinatal event," defined as spontaneous abortion, stillbirth, termination, or death within 24 hours of birth. PURPOSE This study aims to compare associated malformation rates in an atypical perinatal event cohort vs newborns with GS surviving longer than 24 hours. METHODS A national prospective GS database was analyzed for cases with an atypical perinatal event. Associated anomaly rates were compared between this cohort and babies surviving longer than 24 hours. RESULTS Twenty-three atypical perinatal events (2 spontaneous abortions, 7 stillbirths, 11 terminations, and 3 deaths within 24 hours) were identified from 529 total GS cases. Autopsies in 14 (61%) of 23 identified at least 1 anomaly (excluding intestinal, patent ductus arteriosus, and undescended testicle) in 11 (78.6%) and a "lethal" anomaly in 4 (36%). The associated anomaly rate in newborns surviving longer than 24 hours was 7.3% (37/506; P < .0001). The anomalies in the atypical perinatal event cohort were musculoskeletal (35%), cardiac, central nervous system, pulmonary, and genitourinary (12% each). Among survivors, the most common anomalies were cardiac (38%), genitourinary (32%), musculoskeletal (16%), and central nervous system (8%). CONCLUSION Rates of associated anomalies are significantly higher in fetuses experiencing atypical perinatal events and may represent the "hidden mortality" of GS.

Abstract
BACKGROUND There is little information available to inform choice of technique for appendiceal stump control in pediatric laparoscopic appendectomy (LA). We compared complications (stump leak, intra-abdominal abscess formation [IAA], surgical site infection [SSI]) in children undergoing LA for perforated (PA) and nonperforated appendicitis (NPA) by technique of appendiceal stump control. METHODS All children who underwent LA for confirmed acute appendicitis between 2006 and 2009 were reviewed. Choice of stump control (endoloop [EL] or endostapler [ES]) was determined by surgeon preference. Interactions between stump closure techniques and other potential confounders (intra-abdominal drain, irrigation, different antibiotic regimens) were explored using a logistic regression model. RESULTS Of 242 patients undergoing LA, 57 (23.6%) had PA. In the PA group the appendiceal stump was closed with EL in 47 (82.5%) patients, while in the NPA group EL was used in 161 (87%) patients. Among PA patients, IAA was more common in the ES than the EL group (5 of 10 [50%] v. 6 of 47 [12.7%]). There was no significant difference in rates of SSI. Among NPA patients, there were no differences in rates of IAA or SSI. There were no stump leaks in either group. Logistic regression analysis confirmed the predictive effect of ES use on IAA formation in PA (adjusted odds ratio 7.09; 95% confidence interval 1.08-46.13; p = 0.042). CONCLUSION Our data suggest that in most cases of PA, the appendiceal stump can be safely controlled with EL. Within the PA group, the higher rates of IAA seen in ES patients may be attributable to the quality of the appendiceal stump rather than the technique of closure.
