RESUMEN
INTRODUCTION: Postnatal management of antenatally diagnosed ovarian cysts is not well-defined. The clinical course, management, and outcomes of patients with antenatally diagnosed ovarian cysts were reviewed. METHODS: Infants <1 year of age with antenatally diagnosed ovarian cyst managed at The Hospital for Sick Children between January 2017 and December 2021 were included. Patient charts were reviewed for postnatal ultrasound (US) images, management, clinical course and complications. Mixed linear regression analysis was used to model the change in cyst size over time. RESULTS: In total, 52 patients were included and 10 patients had no cyst identified at their first postnatal US. Of the remaining cases, 36% were simple/physiologic and 64% had complex features. Two underwent percutaneous aspiration while 40 patients were managed expectantly with most cysts (62%) resolving. The rate of resolution was significantly higher and faster for simple compared to complex cysts (84% versus 52%, p < 0.05). Cysts that persisted at the end of the study period (n = 14) had all decreased in size, with a rate of resolution similar to resolved cysts. Only one patient managed expectantly required urgent laparoscopy for salpingoophorectomy. CONCLUSION: Antenatally diagnosed ovarian cysts exhibit high rates of resolution with expectant management, supporting the safety and efficacy for expectant management for these patients. LEVEL OF EVIDENCE: III.
RESUMEN
The presence of comorbidities (CM) in congenital lobar emphysema (CLE) has been previously described with varying rates. However, the clinical implication of CM on the clinical presentation and patient outcome in CLE is unclear. This was a retrospective cohort study between 2000 and 2022 in a single institution. The study included pediatric patients diagnosed with CLE. During the study period, 36 patients were identified with CLE. The presence of respiratory symptoms at diagnosis was documented in 69% (24/35) of the patients with 48% admitted to intensive care units. The presence of CM was documented in 14/36 (39%) of the patients, with cardiovascular anomalies as the most common (22%), followed by genitourinary anomalies (11%) and large airway anomalies (8%). When comparing the CM group (n = 14) vs the non-CM group (N = 22), there was no significant difference regarding gender, term birth, age of diagnosis, and the location of the lesion. The CM group had significantly higher rates of intensive care unit (ICU) admissions (75% vs 33%, p = 0.02), longer duration of admission (median 46 days vs 9, p = 0.02), and need for pre-operative non-invasive respiratory support (50% vs 5%, p = 0.002).Conclusion: The presence of CM in CLE was associated with a more severe presentation as reflected with significantly higher rates of ICU admissions, prolonged admissions, and higher need for non-invasive respiratory support. Screening for CM, mostly for cardiac anomalies, is recommended at time of CLE diagnosis. What is Known: ⢠Congenital lobar emphysema (CLE) is a developmental lung anomaly generally associated with other comorbidities; however, their clinical implication on presentation is unclear ⢠The prevalence of comorbidities in CLE was previously reported around 15-20%, with cardiovascular anomalies as the most common What is New: ⢠Comorbidities are very common (39%) in CLE, and their presence is related to a more severe clinical presentation and need for respiratory support ⢠Screening for comorbidities is recommended in CLE, specifically for cardiovascular and genitourinary anomalies.
RESUMEN
Importance: Neonates requiring surgery are often cared for in neonatal intensive care units (NICUs). Despite a breadth of surgical pathology, neonates share many perioperative priorities that allow for the development of unit-wide evidence-based Enhanced Recovery After Surgery (ERAS) recommendations. Observations: The guideline development committee included pediatric surgeons, anesthesiologists, neonatal nurses, and neonatologists in addition to ERAS content and methodology experts. The patient population was defined as neonates (first 28 days of life) undergoing a major noncardiac surgical intervention while admitted to a NICU. After the first round of a modified Delphi technique, 42 topics for potential inclusion were developed. There was consensus to develop a search strategy and working group for 21 topic areas. A total of 5763 abstracts were screened, of which 98 full-text articles, ranging from low to high quality, were included. A total of 16 recommendations in 11 topic areas were developed with a separate working group commissioned for analgesia-related recommendations. Topics included team communication, preoperative fasting, temperature regulation, antibiotic prophylaxis, surgical site skin preparation, perioperative ventilation, fluid management, perioperative glucose control, transfusion thresholds, enteral feeds, and parental care encouragement. Although clinically relevant, there were insufficient data to develop recommendations concerning the use of nasogastric tubes, Foley catheters, and central lines. Conclusions and Relevance: Despite varied pathology, neonatal perioperative care within NICUs allows for unit-based ERAS recommendations independent of the planned surgical procedure. The 16 recommendations within this ERAS guideline are intended to be implemented within NICUs to benefit all surgical neonates.
RESUMEN
OBJECTIVES: Intestinal perforation during acute lymphoblastic leukemia (ALL) treatment in children is rare, but represents a severe complication with possible long-term consequences. In this study, we aim to provide an overview of the epidemiology and clinical characteristics of these patients; analyze surgical pathology findings for possible causes; and determine its impact on patients' therapy, nutritional status, and outcome. STUDY DESIGN: Historical chart review from January 2000 to October 2020 of children with ALL and intestinal perforation during therapy diagnosed at a single institution. Data collected included patient demographics, anthropometric measurements, ALL characteristics, diagnosis and surgery of intestinal perforation, pathology, adjustments to treatment plan, and outcome. RESULTS: Of 1840 ALL patients, 13 (0.7%) presented with intestinal perforation during treatment. Perforation occurred during induction phase in 91% of cases. Most patients underwent laparotomy with ostomy creation, and no patient died from the intervention or developed malnutrition. Pathology mainly revealed inflammation at the perforation site. Two samples showed leukemic infiltration and presence of microorganisms. Patients were able to resume ALL therapy in all cases. A total of eight patients (73%) were in first remission at last follow-up, with a median follow-up time of 42 months (interquartile range = 42). CONCLUSION: Early surgical intervention is a successful treatment approach for intestinal perforation in ALL patients. There is a clear predilection for induction phase in the occurrence of intestinal perforation in ALL patients. No specific cause was identified. Patients can receive bridging chemotherapy during surgical recovery and proceed with their treatment without apparent impact on outcome.

Rationale: Surgical lung biopsies are often required for the definitive diagnosis of nonmalignant pediatric diffuse lung diseases; however, the literature on mortality after surgical lung biopsy in pediatric patients is sparse. Objectives: To determine the 30-day postoperative mortality rate after surgical lung biopsies for nonmalignant lung disease in pediatric patients in Ontario, Canada, and to identify risk factors associated with mortality. Methods: We performed an observational cohort study using population-based health administrative data available from ICES in Ontario, Canada, from 2000 to 2019. Cases were identified using the Canadian Classification of Health Interventions. Inclusion criteria were first surgical lung biopsies between 2000 and 2019 and age <18 years. Individuals with lung cancer, lung transplant, or missing data were excluded. A multivariable logistic regression model with generalized estimating equation was used to estimate the 30-day odds of mortality after surgical lung biopsy and to identify patient characteristics associated with increased mortality while accounting for clustering by hospital. Results: We identified 1,474 pediatric patients who underwent surgical lung biopsy in Ontario between 2000 and 2019. The overall mortality rates decreased over the study duration from 6.6% (2000-2004) to 3.0% (2015-2019). The study cohort for multivariate analyses consisted of 1,342 patients who had complete data. The pediatric mortality 30 days after surgical lung biopsy was 5.1% but was <1% in elective cases. Risk factors for increased mortality included open surgical lung biopsy (vs. video-assisted) (odds ratio [OR], 13.13; 95% confidence interval [CI], 3.76, 45.87; P < 0.001), nonelective procedure (OR, 11.74; 95% CI, 3.51, 39.27; P < 0.001), younger age (<3 mo) (OR, 6.04; 95% CI, 2.40, 15.22; P < 0.001), and higher comorbidity score (OR, 1.15; 95% CI, 1.05, 1.26; P = 0.003). Conclusions: Pediatric mortality postsurgical lung biopsy is not insignificant, particularly in nonelective procedures. Other important risk factors to consider when pursuing pathologic diagnosis include surgical approach, younger age, and higher comorbidity.

OBJECTIVES: To describe the outcomes of preterm born infants with congenital diaphragmatic hernia (CDH; ≤32.0 weeks of gestation) and the associations between prenatal imaging markers and survival. DESIGN: Retrospective cohort study. SETTING: Multicentre study in large referral centres. POPULATION: Infants with an isolated unilateral CDH, live born at 32.0 weeks or less of gestation, between January 2009 and January 2020. METHODS: Neonatal outcomes were evaluated for infants that were expectantly managed during pregnancy and infants that underwent fetoscopic endoluminal tracheal occlusion (FETO) therapy, separately. We evaluated the association between prenatal imaging markers and survival to discharge. Prenatal imaging markers included observed to expected lung-to-head ratio (o/e LHR), side of the defect, liver position, stomach position grade, and observed to expected total fetal lung volume (o/e TFLV). MAIN OUTCOME MEASURE: Survival to discharge. RESULTS: We included 53 infants born at 30+4 (interquartile range 29+1 -31+2 ) weeks. Survival in fetuses expectantly managed during pregnancy was 48% (13/27) in left-sided CDH and 33% (2/6) in right-sided CDH. Survival in fetuses that underwent FETO therapy was 50% (6/12) in left-sided CDH and 25% (2/8) in right-sided CDH. The o/e LHR at baseline was positively associated with survival in cases expectantly managed during pregnancy (odds ratio [OR] 1.20, 95% CI 1.07-1.42, p < 0.01), but not in cases that received FETO therapy (OR 1.01, 95% CI 0.88-1.15, p = 0.87). Stomach position grade (p = 0.03) and o/e TFLV were associated with survival (p = 0.02); liver position was not (p = 0.13). CONCLUSIONS: In infants with CDH born at or before 32 weeks of gestation, prenatal imaging markers of disease severity were associated with postnatal survival.

INTRODUCTION: Surgical (OP) management for symptomatic congenital lobar emphysema (CLE) is the standard of care with nonoperative (NOP) approach applied for asymptomatic cases. The aim of this study is to report the outcomes for NOP approach to the care of symptomatic CLE infants. METHODS: A retrospective study of CLE patients treated 2000-2021 at a single institution. Patients with CLE and respiratory symptoms were included. RESULTS: Overall, 23 children had symptomatic CLE, and 12 had NOP management. The median age at diagnosis was 38.5 days (50) in the NOP group versus 25 days (20) in the OP group (p = 0.31). There was no significant difference in the location of the involved lobe, term birth, postnatal diagnosis and gender, and both groups required noninvasive support in 33% of the cases. There was a trend towards higher frequency of oxygen support in the OP group preoperatively (89% vs. 42%, p = 0.07). The median length of stay was 14 days in the NOP group compared to a median postsurgery stay of 7.5 days in the OP group. In follow-up, there was no significant difference in respiratory readmission in first year of life, growth delay, treatment with asthma medication or body mass index in the NOP versus OP group. None of the children in the NOP group required surgery during follow-up. CONCLUSIONS: A NOP approach for symptomatic CLE infants can have favorable long-term outcomes. Further studies will be required to identify markers to aid in clinical decision-making.

BACKGROUND: Following surgical correction, many patients with esophageal atresia with or without tracheoesophageal fistula (EA/TEF) present to the emergency department (ED) with acute airway complications. We sought to determine the incidence and risk factors for severe acute life-threatening events (ALTEs) in pediatric patients with repaired congenital EA/TEF and the outcomes of operative interventions. METHODS: A retrospective cohort chart review was performed on patients with EA/TEF with surgical repair and follow-up at a single centre from 2000 to 2018. Primary outcomes included 5-year ED visits and/or hospitalizations for ALTEs. Demographic, operative, and outcome data were collected. Chi-square tests and univariate analyses were performed. RESULTS: In total, 266 EA/TEF patients met inclusion criteria. Of these, 59 (22.2%) had experienced ALTEs. Patients with low birth weight, low gestational age, documented tracheomalacia, and clinically significant esophageal strictures were more likely to experience ALTEs (p < 0.05). ALTEs occurred prior to 1 year of age in 76.3% (45/59) of patients with a median age at presentation of 8 months (range 0-51 months). Recurrence of ALTEs after esophageal dilatation was 45.5% (10/22), mostly due to stricture recurrence. Patients experiencing ALTEs received anti-reflux procedures (8/59, 13.6%), airway pexy procedures (7/59, 11.9%), or both (5/59, 8.5%) within a median age of 6 months of life. The resolution and recurrence of ALTEs after operative interventions are described. CONCLUSION: Significant respiratory morbidity is common among patients with EA/TEF. Understanding the multifactorial etiology and operative management of ALTEs have an important role in their resolution. TYPE OF STUDY: Original Research, Clinical Research. LEVEL OF EVIDENCE: Level III Retrospective Comparative Study.

BACKGROUND: Food allergy affects up to 10% of the pediatric population. Despite ongoing efforts, treatment options remain limited. Novel models of food allergy are needed to study response patterns downstream of IgE-crosslinking and evaluate drugs modifying acute events. Here, we report a novel human ex vivo model that displays acute, allergen-specific, IgE-mediated smooth muscle contractions using precision cut intestinal slices (PCIS). METHODS: PCIS were generated using gut tissue samples from children who underwent clinically indicated surgery. Viability and metabolic activity were assessed from 0 to 24 h. Distribution of relevant cell subsets was confirmed using single nucleus RNA sequencing. PCIS were passively sensitized using plasma from peanut allergic donors or peanut-sensitized non-allergic donors, and exposed to various stimuli including serotonin, histamine, FcÉRI-crosslinker, and food allergens. Smooth muscle contractions and mediator release functioned as readouts. A novel program designed to measure contractions was developed to quantify responses. The ability to demonstrate the impact of antihistamines and immunomodulation from peanut oral immunotherapy (OIT) was assessed. RESULTS: PCIS viability was maintained for 24 h. Cellular distribution confirmed the presence of key cell subsets including mast cells. The video analysis tool reliably quantified responses to different stimulatory conditions. Smooth muscle contractions were allergen-specific and reflected the clinical phenotype of the plasma donor. Tryptase measurement confirmed IgE-dependent mast cell-derived mediator release. Antihistamines suppressed histamine-induced contraction and plasma from successful peanut OIT suppressed peanut-specific PCIS contraction. CONCLUSION: PCIS represent a novel human tissue-based model to study acute, IgE-mediated food allergy and pharmaceutical impacts on allergic responses in the gut.

Background: Prolonged mechanical ventilation (MV) should be avoided in neonates. Noninvasive ventilation (NIV) can facilitate weaning from MV but has risks for patients immediately following foregut surgery due to the potential risk of anastomotic leak. We evaluated the risk factors for prolonged MV following intestinal surgery in neonates. Methods: We retrospectively reviewed 253 neonates undergoing intestinal surgery in 2017-2018 to identify risk factors for prolonged MV, and determine the correlation between NIV and anastomotic leak in a tertiary neonatal intensive care unit that performs the greatest number of neonatal surgeries in Ontario. Results: The most common diagnoses were necrotizing enterocolitis/spontaneous intestinal perforation (NEC/SIP) 21%, intestinal atresia 16%, esophageal atresia/tracheoesophageal fistula 14%, ano-rectal malformation 13%, malrotation/volvulus 11%, gastroschisis 9% and omphalocele 4%. The median (IQR) duration of MV post-surgery was 3 (1-8) days with 25.7 % (n=65) of neonates on MV for >7 days. Compared to infants on MV post-surgery for ≤7 days, those with MV>7 days were of lower gestational age, birth weight and weight at surgery, but a higher proportion underwent stoma creation, had a longer duration of opioid administration and higher rates of moderate to severe bronchopulmonary dysplasia (BPD) and mortality (P<0.05). Generalized linear regression analysis showed lower gestational age (GA) and longer opioid administration were associated with longer duration of MV (P<0.001), but indication for surgery, weight at surgery and stoma creation didn't correlate with longer duration of MV (P>0.05). Of the 122 patients handled by one-stage resection with primary anastomosis, 22.1% (n=27) received NIV with 74.1% (n=20) commenced on NIV after 7 days post-surgery, anastomotic leak was detected in 2.5 % (3/122) patients and didn't correlate with NIV. Conclusions: Lower GA and longer opioid administration were risk factors for prolonged MV in neonates following intestinal surgery. Further research is needed to investigate modifiable practices around pain assessment/ventilation in these patients, and the correlation between NIV and anastomotic leak.
RESUMEN
Airway clearance is an essential part of airway maintenance to ensure the airway lumen is protected against particulate and infectious insults. The mechanisms involved in airway clearance include intrinsic structural and cellular components that can be impaired or inhibited through developmental defects and surgical interventions. Tracheomalacia is a developmental defect of the airway that can contribute to the mechanical failure to clear the airway. This chapter will review the mechanisms of airway clearance and the processes that can impair this vital process.

Microcystic congenital cystic adenomatoid malformations (CCAM), when associated with hydrops, carry a dismal prognosis. Options for treatment are limited and experimental, including antenatal corticosteroids, open fetal surgery, laser ablation and, more recently, sclerotherapy. We describe a case of a large, predominantly microcystic CCAM in a hydropic fetus treated successfully with direct interstitial injection of a sclerosant agent (3% sodium tetradecyl sulfate) at 23+3 weeks gestation, after multiple failed courses of steroids. Elective thoracoscopic right lower lobectomy was performed at 1 year of life and there have been no respiratory or other medical morbidities since. A literature review of fetal lung masses treated with sclerosants antenatally reveals that sclerotherapy may represent a novel treatment option for large hydropic microcystic CCAMs, which are unresponsive to corticosteroids. Further studies are required to evaluate the utility and safety of fetal sclerotherapy, as this may represent an alternative minimally invasive treatment option to fetal lobectomy.

BACKGROUND: Contemporary outcomes of infants with esophageal atresia with or without tracheoesophageal fistula (EA/TEF) from multi-gestational pregnancies compared to those of singleton pregnancies have not been reported. METHODS: A single-center retrospective review of EA/TEF patients born from 1999 to 2013 was performed. Patient demographics, gestational age (GA), birth weight, associated anomalies, requirement for gastrostomy tube and mortality were reviewed. RESULTS: Singleton EA/TEF patients outnumbered those from multi-gestational pregnancies nearly 10:1 (214 vs 22 patients). EA/TEF patients from multi-gestational pregnancies were more likely to be premature (77% vs. 32%), have lower birth weight (mean 1766â¯g vs. 2695â¯g), have associated duodenal atresia (18% vs. 6%) and require gastrostomy tube (41% vs. 33%) for feeding challenges compared to EA/TEF singletons. Mortality was also significantly greater for multi-gestational EA/TEF patients compared to singleton EA/TEF patients (18% vs. 6%). CONCLUSION: EA/TEF infants from multi-gestational pregnancies have greater clinical complexity and mortality than singleton EA/TEF patients. Parents of EA/TEF multi-gestational infants should be appropriately counseled and supported.

PURPOSE: Oral feeds pose a challenge for congenital diaphragmatic hernia (CDH) infants. Tube feed (TF) supplementation may be required to support the achievement of normal growth. The aim of this study was to determine the duration and factors associated with TF use in CDH infants at our institution. METHODS: A single centre retrospective chart review was performed for CDH-born infants who underwent repair between 2000 to 2013 (REB #1000053124). Patient demographics, perinatal management, and feeding status of infants with at least 1-year follow-up were reviewed. RESULTS: Of 160 CDH infants, 32 (20%) were discharged on partial or complete TF, and an additional 5 (3.1%) patients started TF post discharge. CDH infants with TF were more likely to have initial arterial blood pHâ¯<â¯7.25, patch repair, ECMO support, and prolonged ICU stay (pâ¯<â¯0.05). Time to TF discontinuation did not differ significantly between those partially or fully TF at discharge. Twelve patients (33.3%) remained TF at their last known follow-up. CONCLUSION: High risk CDH patients are likely to require TF to support their nutritional intake. Parents and caregivers need to be informed and properly supported. Long-term monitoring of CDH patient oral intake, growth, and development will be required. LEVEL OF EVIDENCE/TYPE OF STUDY: Level III Retrospective Study.

PURPOSE: The aim is to identify prognostic markers of long-term pulmonary morbidity among congenital diaphragmatic hernia (CDH) survivors. METHODS: A single-institution, retrospective review was performed on all CDH patients from 2000 and 2012 (REB#1000053383). Liver position, patch use, and pulmonary function tests (PFTs) (forced expiratory volume at 1 second [FEV1] and forced vital capacity [FVC] expressed as mean % predicted + SD) were recorded. Data were analyzed using analysis of variance. RESULTS: Patients with acceptable and reproducible PFT (n = 72 for 202 total PFT) with patch repair and liver up (n = 28) had significantly lower FEV1 (72.4 + 17.6) than those with no patch and liver down (n = 98, FEV1= 86.3 + 15.9, p = 0.002). Patients with patch repair and liver down (n = 40) also had significantly lower FEV1 (76.6 + 14.4) than those with liver down and no patch (p = 0.0463). Patients with liver up and patch repair had PFT results consistent with moderate reduction of lung function, while the remainder had mild to no decrease in lung function. All CDH patients older than 14 years had a reduction in FEV1/FVC consistent with obstructive phenotype, with a mean FEV1/FVC = 62.3 for patch repair group and FEV1/FVC = 76.1 in the no patch group. CONCLUSION: Decreased pulmonary function of CDH survivors correlated with the use of patch repair and liver position. CDH lung disease should be monitored in adulthood.

Prenatal observed/expected lung-to-head ratio (O/E LHR) by ultrasound correlates with postnatal mortality for congenital diaphragmatic hernia (CDH) patients. The aim of this study is to determine if O/E LHR correlates with pulmonary hypertension (PH) outcomes for CDH patients. METHODS: A single center retrospective chart review was performed for CDH neonates from January 1, 2006, to December 31, 2015, (REB #1000053124) to include prenatal O/E LHR, liver position, first arterial blood gas, repair type, echocardiogram (ECHO), and lung perfusion scan (LPS) results up to 5years of age. RESULTS: Of 153 newborns, 123 survived (80.4%), 58 (37.9%) had prenatal O/E LHR, and 42 (27.5%) had postnatal ECHO results. High mortality risk neonates (O/E LHR ≤45%) correlated with higher right ventricular systolic pressure (RVsp) at birth. Generally PH resolved by age 5years. LPS results did not change over time (p>0.05) regardless of initial PH severity, suggesting that PH resolution did not correlate with increased ipsilateral lung perfusion to offload the right ventricle. CONCLUSION: Prenatal prognostic markers correlated with initial PH severity for CDH newborns, but PH resolved over time despite fixed perfusion bias to the lungs. These results suggest favorable PH outcomes for CDH patients who survive beyond infancy. TYPE OF STUDY: Retrospective Cohort Study. LEVEL OF EVIDENCE: 3b.

BACKGROUND: The provision of timely and comprehensive transition of care from pediatric to adult surgical providers for patients who have undergone childhood operations remains a challenge. Understanding the barriers to transition from a patient and family perspective may improve this process. METHODS: A cross-sectional survey was conducted of patients with a history of anorectal malformation (ARM) or Hirschsprung Disease (HD) and their families. The web-based survey was administered through two support groups dedicated to the needs of individuals born with these congenital abnormalities. Categorical variables were compared using Chi-squared and Fisher's exact test with Student's t test and ANOVA for continuous variables. RESULTS: A total of 118 surveys were completed (approximately 26.2% response). The average age of patients at time of survey was 12.3years (SD 11.6) with 64.5% less than 15years old. The primary diagnosis was reported for 78.8% patients and included HD (29.0%), ARM (61.3%), and cloaca (9.7%). The average distance traveled for ongoing care was 186.6miles (SD 278.3) with 40.9% of patients traveling ≥30miles; the distance was statistically significantly greater for patients with ARM (p<0.001). With regards to ongoing symptoms, 44.1% experience constipation, 40.9% experience diarrhea, and approximately 40.9% require chronic medication for management of bowel symptoms; only 3 respondents (3.2%) reported fecal incontinence. The majority of patients, 52.7% reported being seen by a provider at least twice per year and the majority continued to be followed by a pediatric provider, consistent with the majority of the cohort being less than 18years of age. Conversations with providers regarding transitioning to an adult physician had occurred in fewer than 13% of patients. The most commonly cited barrier to transition was the perception that adult providers would be ill-equipped to manage the persistent bowel symptoms. CONCLUSION: Patients undergoing childhood procedures for ARM or HD have a high prevalence of ongoing symptoms related to bowel function but very few have had conversations regarding transitions in care. Early implementation of transitional care plans and engagement of adult providers are imperative to transitions and may confer long-term health benefits in this patient population. LEVEL OF EVIDENCE: Level IV, case series with no comparison group.

PURPOSE: The surgical management of neonates with duodenal atresia (DA) involves re-establishment of intestinal continuity, either by duodeno-duodenostomy (DD) or by duodeno-jejunostomy (DJ). Although the majority of pediatric surgeons perform DD repair preferentially, we aimed to analyze the outcome of DA neonates treated with either surgical technique. METHODS: Following ethical approval (REB:1000047737), we retrospectively reviewed the charts of all patients who underwent DA repair between 2004 and 2014. Patients with associated esophageal/intestinal atresias and/or anorectal malformations were excluded. Outcome measures included demographics (gender, gestational age, and birth weight), length of mechanical ventilation, time to first and full feed, length of hospital admission, weight at discharge (z-scores), and postoperative complications (anastomotic stricture/leak, adhesive obstruction, and need for re-laparotomy). Both DD and DJ groups were compared using parametric or non-parametric tests, with data presented as mean ± SD or median (interquartile range). RESULTS: During the study period, 92 neonates met the inclusion criteria. Of these, 47 (51%) had DD and 45 (49%) DJ repair. All procedures were performed open, apart from one laparoscopic DJ. Overall, DD and DJ groups had similar demographics. Likewise, we found no differences between the two groups for length of ventilation (p = 0.6), time to first feed (p = 0.5), time to full feed (p = 0.4), length of admission (p = 0.6), prokinetic use (p = 0.5), nor weight at discharge (p = 0.1). When the 30/92 (33%) patients with trisomy-21 (DD = 16, DJ = 14) were excluded from analysis, the groups still had similar weight at discharge (p = 0.2). Postoperative complication rate was not different between the two groups. One patient per group died, due to respiratory failure (DD) and sepsis (DJ). CONCLUSIONS: This study demonstrates that in neonates with duodenal atresia, duodeno-duodenostomy and duodeno-jejunostomy have similar outcomes. These findings are relevant for surgeons who repair duodenal atresia laparoscopically, as duodeno-jejunostomy had equal clinical outcomes and may be easier to perform.

BACKGROUND: Malnutrition is common among congenital diaphragmatic hernia (CDH) survivors and may result from elevated respiratory effort. We evaluated body mass index (BMI), measured resting energy expenditure (mREE) and pulmonary function test (PFT) results in children and adolescents with CDH to determine if there is a correlation. METHODS: With ethics approval (REB# 1000035323), anthropometrics, indirect calorimetry (IC) results and PFTs were collected from patients 5-17years of age during CDH clinic visits between 2000 and 2016. Malnutrition was defined as BMI z-scores <-2.0; mREE (as percent predicted REE) was measured using IC; z-scores for forced expiratory volume in 1s (FEV1) and forced vital capacity (FVC) were normal if <-1.64. STATISTICS: GraphPad Prism 6, San Diego, CA. RESULTS & DISCUSSION: Of 118 patients who attended clinic, 33 had reproducible PFTs, anthropometrics and IC results. Mean BMI z-score was -0.89±1.47 and 24% of patients were malnourished; mean FVC z-score (-1.32±1.39) was within normal range, whereas mean z-scores for FEV1 (-2.21±1.68) and FEV1/FVC ratio (-1.78±0.73) were below normal. A correlation was noted between BMI and PFTs (FEV1 r=0.70, P<0.0001; FVC r=0.74 P<0.0001). Mean mREE was 112%±12% of expected and 67% of patients were hypermetabolic (mREE<110% predicted). IC results did not correlate with z-scores for either FEV1 (r=0.10, P=0.57); or FVC (r=0.28, P=0.12). CONCLUSIONS: These preliminary results suggest that a correlation is present between BMI and lung function in CDH children and adolescents, whereas lung function does not seem to correlate with mREE.
