Patient characteristics are important determinants of neurodevelopmental outcome during infancy in giant omphalocele

Morbidity in giant omphaloceles: Predictive factors and management strategies

AIM

To identify predictors of morbidity in GO through an analysis of associated anomalies, defect characteristics and management strategies.

METHODS

PubMed and Ovid EMBASE databases were searched from 2013 to 2023. Primary end points assessed correlation of morbidity with gestational age (GA), birth weight (BW), eviscerated organs, defect size, associated anomalies and management strategy.

RESULTS

Twenty articles were included for analysis with a total of 1009 GO. Median GA was 37 weeks (27-41), with a median BW of 2700 g (900-6000). 143 cardiovascular anomalies, 238 pulmonary anomalies, 98 musculoskeletal anomalies, 53 urogenital anomalies, 94 gastrointestinal anomalies, 11 neurological anomalies and 43 chromosomal anomalies were identified. 82 had unspecified additional anomalies, of which 20 and 17 were defined as major and minor, respectively. 123 neonates were managed with primary closure, 206 neonates with staged closure and 312 neonates with conservative treatment. Complications included sepsis, respiratory compromise, feeding dysfunction and closure-related adverse events. Long-term morbidity included home ventilation (n = 72), long-term parental nutrition (n = 36), and delayed motor neurodevelopment (n = 21). Main predictors of morbidity were pulmonary hypertension/hypoplasia, major congenital anomalies, greater defect size and liver herniation.

CONCLUSION

Key predictors of poor outcomes include the presence of additional congenital anomalies, defect size, liver herniation and pulmonary hypertension/hypoplasia.

Longitudinal growth of children born with gastroschisis or omphalocele

Normal childhood growth is an indicator of good health, but data addressing the growth of children born with abdominal wall defects (AWDs) are limited. The detailed growth phenotypes of children born with gastroschisis or omphalocele are described and compared to peers without AWDs from birth to adolescence. Data from 183 gastroschisis and 144 omphalocele patients born between 1993 and 2017 were gathered from Finnish nationwide registers and electronic health records. Weight (n = 3033), length/height (n = 2034), weight-for-length (0-24 months, n = 909), and body mass index measures (2-15 years, n = 423) were converted into sex- and age-specific Z-scores. Linear mixed models were used for comparisons. Intrauterine growth failure was common in infants with gastroschisis. Birth weight Z-scores in girls and boys were - 1.2 (0.2) and - 1.3 (0.2) and length Z-scores - 0.7 (0.2) and - 1.0 (0.2), respectively (p < 0.001 for all comparisons to infants without AWDs). During early infancy, growth failure increased in infants with gastroschisis, and thereafter, catch-up growth was prominent and faster in girls than in boys. Gastroschisis children gained weight and reached their peers' weights permanently at 5 to 10 years. By 15 years or older, 30% of gastroschisis patients were overweight. Infants with omphalocele were born with a normal birth size but grew shorter and weighing less than the reference population until the teen-age years.

CONCLUSION

Children with gastroschisis and omphalocele have distinct growth patterns from fetal life onwards. These growth trajectories may also provide some opportunities to modulate adult health.

WHAT IS KNOWN

• Intrauterine and postnatal growth failure can be seen frequently in gastroschisis and they often show significant catch-up growth later in infancy. It is assumed that part of the children with gastroschisis will become overweight during later childhood.

WHAT IS NEW

 • The longitudinal growth of girls and boys with gastroschisis or omphalocele is described separately until the teenage years. The risk of gaining excessive weight in puberty was confirmed in girls with gastroschisis.

Echocardiographic measurements of left ventricular dimensions and function in newborns with omphalocele and pulmonary

PURPOSE

The purpose of this study was to explore echocardiographic parameters of the left ventricle (LV) in relation to the outcomes of omphalocele neonates with pulmonary hypertension (PH).

METHODS

This retrospective study was conducted among omphalocele patients with PH born from 2019 to 2020. Patients in this study did not have additional severe malformations or chromosomal aberrations. Patients who died under palliative care were excluded. The echocardiographic parameters of LV were obtained within 24 h after birth. Clinical and outcomes data were recorded, echocardiograms evaluated for left ventricular internal dimension in end-diastole (LVIDd), end-diastolic volume (EDV), stroke volume (SV) and cardiac output index (CI), among others.

RESULTS

There were 18 omphalocele newborns with PH, of whom 14 survived and 4 died. Both groups were comparable in the baseline characteristics. Non-survival was associated with a smaller LV [LVIDd (12.2 mm versus15.7 mm, p < 0.05), EDV (3.5 ml versus 6.8 ml, p < 0.05)] and with worse systolic function [SV (2.3 ml versus 4.2 ml, p < 0.05), and CI (1.7 L/min/m2 versus 2.9 L/min/m2, p < 0.01)].

CONCLUSION

In the cohort of omphalocele patients with PH, lower LVIDd, EDV, SV and CI were associated with mortality.

Neurodevelopmental outcome of patients with congenital gastrointestinal malformations: a systematic review and meta-analysis

AIM

Children with congenital gastrointestinal malformations may be at risk of neurodevelopmental impairment due to challenges to the developing brain, including perioperative haemodynamic changes, exposure to anaesthetics and postoperative inflammatory influences. This study aggregates existing evidence on neurodevelopmental outcome in these patients using meta-analysis.

METHOD

PubMed, Embase and Web of Science were searched for peer-reviewed articles published until October 2019. Out of the 5316 unique articles that were identified, 47 studies met the inclusion criteria and were included. Standardised mean differences (Cohen's d) between cognitive, motor and language outcome of patients with congenital gastrointestinal malformations and normative data (39 studies) or the studies' control group (8 studies) were aggregated across studies using random-effects meta-analysis. The value of (clinical) moderators was studied using meta-regression and diagnostic subgroups were compared.

RESULTS

The 47 included studies encompassed 62 cohorts, representing 2312 patients. Children with congenital gastrointestinal malformations had small-sized cognitive impairment (d=-0.435, p<0.001; 95% CI -0.567 to -0.302), medium-sized motor impairment (d=-0.610, p<0.001; 95% CI -0.769 to -0.451) and medium-sized language impairment (d=-0.670, p<0.001; 95% CI -0.914 to -0.425). Patients with short bowel syndrome had worse motor outcome. Neurodevelopmental outcome was related to the number of surgeries and length of total hospital stay, while no relations were observed with gestational age, birth weight, age and sex.

INTERPRETATION

This study shows that children with congenital gastrointestinal malformations exhibit impairments in neurodevelopmental outcome, highlighting the need for routine screening of neurodevelopment during follow-up.

Predicting neonatal outcomes in infants with giant omphalocele using prenatal magnetic resonance imaging calculated observed-to-expected fetal lung volumes

OBJECTIVE

To examine the association between prenatal magnetic resonance imaging (MRI) based observed/expected total lung volume (O/E TLV) and outcome in neonates with giant omphalocele (GO).

METHODS

Between 06/2004 and 12/2019, 67 cases with isolated GO underwent prenatal and postnatal care at our institution. MRI-based O/E TLVs were calculated based on normative data from Meyers and from Rypens and correlated with postnatal survival and morbidities. O/E TLV scores were grouped based on severity into <25% (severe), between 25% and 50% (moderate), and >50% (mild) for risk stratification.

RESULTS

O/E TLV was calculated for all patients according to Meyers nomograms and for 49 patients according to Rypens nomograms. Survival for GO neonates with severe, moderate, and mild pulmonary hypoplasia based on Meyers O/E TLV categories was 60%, 92%, and 96%, respectively (p = 0.04). There was a significant inverse association between Meyers O/E TLV and risk of neonatal morbidities (p < 0.05). A similar trend was observed with Rypens O/E TLV, but associations were less often significant likely related to the smaller sample size.

CONCLUSION

Neonatal outcomes are related to fetal lung size in isolated GO. Assessment of Meyers O/E TLV allows identification of GO fetuses at greatest risk for complications secondary to pulmonary hypoplasia.

Potential Risk Factors for Autism in Children Requiring Neonatal Intensive Care Unit

BACKGROUND

The etiology of autism spectrum disorder (ASD) is complex and involves the interplay of genetic and environmental factors.

AIM

We sought to identify potential prenatal, perinatal, and neonatal risk factors for ASD in a unique population of children who had perinatal complications and required care in a neonatal intensive care unit (NICU).

METHODS

This prospective cohort study included 73 patients discharged from a NICU who received long-term follow-up at the largest children's hospital in Brazil. Potential risk factors were compared between 44 children with a diagnosis of ASD and 29 children without using the Mann-Whitney U test. Proportions were analyzed using the chi-square test. Simple and multiple logistic regression tests were performed.

RESULTS

Of 38 factors analyzed, the following 7 were associated with ASD: family history of neuropsychiatric disorders (p = 0.049); maternal psychological distress during pregnancy (p = 0.007); ≥ 26 days in the NICU (p = 0.001); feeding tube for ≥ 15 days (p = 0.014); retinopathy of prematurity (p = 0.022); use of three or more antibiotics (p = 0.008); and co-sleeping until up to 2 years of age (p = 0.004).

CONCLUSION

This study found associations between specific risk factors during critical neurodevelopmental periods and a subsequent diagnosis of ASD. Knowledge of the etiologic factors that may influence the development for ASD is paramount for the development of intervention strategies and improvement of prognoses.

Comparison of outcomes of infants with giant omphaloceles over two decades

BACKGROUND

The purpose of this study was to compare the outcomes of infants with giant omphalocele (GO) born in two different epochs over two decades at a single institution. Specifically, it examined whether the utilization of selective pulmonary vasodilators and extracorporeal membrane oxygenator (ECMO) in the management of pulmonary hypertension in the second epoch were associated with improved outcomes.

METHODS

The medical records of all patients diagnosed with GO at a large children's hospital from January 1, 1996 to December 31, 2016 were reviewed and divided into two epochs. Patients were classified as having an isolated GO or GO with minor or major associated anomalies. GO was defined as a defect more than or equal to 5 cm in size and/or liver in the sac.

RESULTS

During the study period, 59 infants with GO were identified. The duration of invasive mechanical ventilation was significantly shorter among the survivors from the second epoch (p = 0.03), with none greater than seven days. There were no significant differences in the outcomes of survival to NICU discharge and length of stay (LOS) between infants in the two epochs.

CONCLUSIONS

Infants with GO who required invasive mechanical ventilation for more than seven days did not survive in the second epoch. Survival did not improve with uses of selective pulmonary vasodilators and ECMO. This information could be shared with families during prenatal and postnatal counselling to facilitate informed decision making regarding goals of care.

Major abdominal wall defects in the low- and middle-income setting: current status and priorities

Major congenital abdominal wall defects (gastroschisis and omphalocele) may account for up to 21% of emergency neonatal interventions in low- and middle-income countries. In many low- and middle-income countries, the reported mortality of these malformations is 30-100%, while in high-income countries, mortality in infants with major abdominal wall reaches less than 5%. This review highlights the challenges faced in the management of newborns with major congenital abdominal wall defects in the resource-limited setting. Current high-income country best practice is assessed and opportunities for appropriate priority setting and collaborations to improve outcomes are discussed.

Omphalocele at school age: What do parents report? A call for long-term follow-up of complex omphalocele patients

OBJECTIVE

Many children with omphalocele experience morbidity in early life, which could affect long-term outcomes. We determined parent-reported outcomes in school-aged children treated for minor or giant omphalocele.

STUDY DESIGN

We sent paper questionnaires to the parents of all children treated for omphalocele in 2000-2012. Giant omphalocele was defined as defect diameter ≥ 5 cm with liver protruding. Motor function (MABC-2 Checklist) was compared with Dutch reference data; cognition (PedsPCF), health status (PedsQL), quality of life (DUX-25) and behavior (Strengths and Difficulties Questionnaire; SDQ) were compared with those of controls (two per child) matched for age, gender and maternal education level. Possible predictors of cognition and behavior were evaluated using linear regression analyses.

RESULTS

Of 54 eligible participants, 31 (57%) returned the questionnaires. MABC-2 Checklist scores were normal for 21/26 (81%) children. Cognition, health status, quality of life and behavior were similar to scores of matched controls. One quarter (26%) of children with omphalocele scored ≤ - 1 standard deviation on the PedsPCF, compared with 9% of matched controls (p = 0.07). Giant omphalocele and presence of multiple congenital anomalies (MCA) were most prominently associated with lower PedsPCF scores (giant omphalocele: β -22.11 (95% CI: -43.65 to -0.57); MCA -23.58 (-40.02 to -7.13)), although not significantly after correction for multiple testing.

CONCLUSIONS

Parent-reported outcomes of children with omphalocele at school age are reassuring. Children with an isolated, minor omphalocele do not need extensive long-term follow-up of daily functioning. Those with a giant omphalocele or MCA might be at risk for delayed cognitive functioning at school age; we recommend long-term follow-up to offer timely intervention.

Autism spectrum disorder and neurodevelopmental delays in children with giant omphalocele

OBJECTIVE

To determine the prevalence and identify risk factors of autism spectrum disorders (ASDs) and neurodevelopmental delays in giant omphalocele (GO) survivors.

MATERIALS AND METHODS

The study cohort consists of 47 GO survivors enrolled in our follow-up program between 07/2004 and 12/2015. All patients underwent assessments at 2 years of age or older. Outcomes were assessed by either the Bayley Scales of Infant Development II (prior 2006) or III (after 2006), or the Wechsler Preschool and Primary Scale of Intelligence (children older than 4 years). ASD diagnosis was made based on the Diagnostic and Statistical Manual of Mental Disorders IV (prior to 2014) or 5 criteria.

RESULTS

The prevalence of ASD in GO children is 16 times higher than the general population (P = 0.0002). ASD patients were more likely to be diagnosed with neurodevelopmental and neurofunctional delays, language disorders, and genetic abnormalities (P < 0.01). While 53.2% of GO children scored within the average range for all developmental domains, 19.1% scored within the mildly delayed and 27.7% in the severe delayed range in at least one domain. Prolonged respiratory support, pulmonary hypertension, gastroesophageal reflux disease, feeding problems, prolonged hospitalization, abnormal BAER hearing screen, presence of delayed motor coordination, and hypotonicity were associated with delayed scores (P < 0.05).

CONCLUSIONS

There is a significant rate of ASD in GO survivors. Neurodevelopmental delays, language delays, and genetic abnormalities were strongly associated with ASD. Neurological impairments were present in nearly half of GO children. Surrogate markers of disease severity were associated with below average neurodevelopmental scores. Level of evidence Level IV.

Prenatally diagnosed omphalocele: characteristics associated with adverse neonatal outcomes

OBJECTIVE

To characterize factors associated with adverse neonatal outcomes in prenatally diagnosed omphalocele cases.

STUDY DESIGN

Prenatally diagnosed omphalocele cases at a single referral center from 1 January 2009 to 31 December 2017 were retrospectively reviewed. Clinical variables and antenatal imaging measurements were collected. Associations between prenatal and neonatal characteristics and the adverse outcome of death or prolonged length of stay (LOS) were analyzed.

RESULTS

Out of 63 fetal cases, 33 were live-born, > 50% had other anomalies, and neonatal mortality was 12%. Adverse outcomes were associated with neonatal variables, including lower median 1-min Apgar score, initial mechanical ventilation, and late-onset sepsis, but not approach to omphalocele closure. With multivariate analysis, death or prolonged LOS was associated only with low lung volumes by fetal MRI (OR 34 (3-422), p = 0.006).

CONCLUSION

Low lung volumes by fetal MRI were associated with death or prolonged LOS in neonates with prenatally diagnosed omphalocele and may guide clinicians with counseling families.

Outcomes in omphalocele correlate with size of defect

BACKGROUND

Omphaloceles can be some of the more challenging cases managed by pediatric surgeons. Single center studies have not been meaningful in delineating outcomes due to the length of time required to accumulate a large enough series with historical changes in management negating the results. The purpose of this study was to evaluate factors impacting the morbidity and mortality of neonates with omphaloceles.

METHODS

A multicenter, retrospective observational study was performed for live born neonates with omphalocele between 2005 and 2013 at nine centers in the United States. Maternal and neonatal data were collected for each case. In-hospital management and outcomes were also reported and compared between neonates with small and large omphaloceles.

RESULTS

Two hundred seventy-four neonates with omphalocele were identified. The majority were delivered by cesarean section with a median gestational age of 37 weeks. Overall survival to hospital discharge was 81%. The presence of an associated anomaly was common, with cardiac abnormalities being the most frequent. Large omphaloceles had a significantly longer hospital and ICU length of stay, time on ventilator, number of tracheostomies, time on total parenteral nutrition, and time to full feeds, compared to small omphaloceles. Birth weight and defect size were independent predictors of survival.

CONCLUSION

This is the largest contemporary study of neonates with omphalocele. Increased defect size is an independent predictor of neonatal morbidity and mortality.

LEVEL OF EVIDENCE

Impact of Breast Milk, Respiratory Insufficiency, and Gastroesophageal Reflux Disease on Enteral Feeding in Infants With Omphalocele

OBJECTIVES

The aim of this study was to document the process of achieving full enteral feeding in infants with omphalocele and to identify factors that affect feeding success.

METHODS

After institutional review board approval (study no. 5100169), 123 infants with omphalocele, born between 1993 and 2011 were reviewed. Mortalities were excluded. All survivors had complete follow-up. Variables suspected to impact enteral feeding in infants with non-giant versus giant omphalocele were compared. Independent t test, Mann-Whitney, and χ test were used. Regression evaluated for variable independence.

RESULTS

Of 123 infants with omphalocele, 97 (79%) survived, 62/97 (64%) had non-giant, and 35/97 (36%) giant omphalocele. For survivors, the mean gestational age was 37 ± 4 weeks with median follow-up of 4.4 years (range: 1.4-7.4 years). The median time to full feeds was 4 days (range: 0-85 days) for non-giant versus 8 days (range: 1-96 days) for giant, a significant difference (P < 0.01). Breast milk significantly decreased time to full feeds independent of omphalocele size. Giant omphalocele infants had a significantly higher incidence of respiratory insufficiency at birth (P < 0.01) and sac rupture (P = 0.02), but fewer chromosomal anomalies (P = 0.04). Respiratory insufficiency at birth (P < 0.01) and gastroesophageal reflux disease (P < 0.01) independently delayed feeding in omphalocele infants.

CONCLUSIONS

Infants with non-giant omphalocele can achieve full enteral feeds within the first week of life, but giant omphalocele infants require significantly more time. Breast milk independently promotes feeding success whereas gastroesophageal reflux disease and respiratory insufficiency at birth independently delay feeding in infants with omphalocele.

Long term complications and outcomes in omphalocele

After a diagnosis of omphalocele during pregnancy, questions regarding long-term prognosis are of primary importance for parents. It is imperative that their questions are answered with substantiated data to promote confident decisions for their children. They frequently express concerns regarding long-term survival, quality of life, need for more operations, feeding issues, motor and cognitive development, cosmesis, and the unique difficulties of giant omphaloceles. The available outcome studies that address these questions are discussed.

Omphalocele: from diagnosis to growth and development at 2 years of age

OBJECTIVES

To compare the prenatal frame of reference of omphalocele (ie, survival of fetuses) with that after birth (ie, survival of liveborn neonates), and to assess physical growth and neurodevelopment in children with minor or giant omphalocele up to 2 years of age.

DESIGN

We included fetuses and neonates diagnosed in 2000-2012. Physical growth (SD scores, SDS) and mental and motor development at 12 and 24 months were analysed using general linear models, and outcomes were compared with reference norms. Giant omphalocele was defined as defect ≥5 cm, with liver protruding.

RESULTS

We included 145 fetuses and neonates. Of 126 (87%) who were diagnosed prenatally, 50 (40%) were liveborn and 35 (28%) survived at least 2 years. Nineteen (13%) neonates were diagnosed after birth. Of the 69 liveborn neonates, 52 (75%) survived and 42 children (81% of survivors) were followed longitudinally. At 24 months, mean (95% CI) height and weight SDS were significantly below 0 in both minor (height: -0.57 (-1.05 to -0.09); weight: -0.86 (-1.35 to -0.37)) and giant omphalocele (height: -1.32 (-2.10 to -0.54); weight: -1.58 (-2.37 to -0.79)). Mental development was comparable with reference norms in both groups. Motor function delay was found significantly more often in children with giant omphalocele (82%) than in those with minor omphalocele (21%, P=0.002).

CONCLUSIONS

The prenatal and postnatal frames of reference of omphalocele differ considerably; a multidisciplinary approach in parental counselling is recommended. As many children with giant omphalocele had delayed motor development, we recommend close monitoring of these children and early referral to physical therapy.

Rate and Risk Factors Associated with Autism Spectrum Disorder in Congenital Diaphragmatic Hernia

To determine the rate and predictors of autism spectrum disorder (ASD) in congenital diaphragmatic hernia (CDH). Between 06/2004 and 09/2015 a total of 110 CDH survivors underwent neurodevelopmental (ND) testing and screening for ASD, followed by a full autism diagnostic evaluation if indicated at our institution. We found a 9 time higher rate of ASD in CDH children compared to the general population (P = 0.0002). Multiple patient-related and clinical variables risk factors of ASD were identified by univariate analysis. However, only short-term and long-term neurodevelopmental delays were strongly associated with ASD in CDH by multivariate comparisons. There is a striking prevalence of ASD in CDH survivors and our findings suggest that all CDH children should be regularly screened for ASD.

Short-Term Neurodevelopmental Outcome in Children Born With High-Risk Congenital Lung Lesions

BACKGROUND

This study sought to evaluate neurodevelopmental outcome in survivors of high-risk congenital lung lesions (CLLs) who underwent prenatal intervention or postnatal surgery within the first month of life.

METHODS

Forty-five high-risk CLL survivors underwent assessment using the Bayley Scales of Infant Development, 3rd Edition between July 2004 and December 2016. Scores were grouped as average, at-risk, and delayed based on SD intervals. Correlations between outcome and risk factors were analyzed by Fisher's exact test or two-sided t test as appropriate, with significant p values <0.05.

RESULTS

Open prenatal intervention was required in 13 (28.9%) children (fetal surgical resection, n = 4 , ex utero intrapartum treatment, n = 9), whereas 32 (71.1%) children had respiratory distress postnatally and required resection within the first month of life. Mean age at follow-up was 19.3 ± 10.3 months. Mean composite scores were within the expected average range. A total of 62.2% scored within the average range for all domains. At-risk scores were found in 26.7% of children in at least one domain, and 11.1% had delays in at least one domain. Neurodevelopmental outcome was similar between treatment groups. Prolonged ventilator support and neonatal intensive care unit stay, need for supplemental oxygen at day of life 30, gastroesophageal reflux disease, and delayed enteral feeding were associated with neurologic delays (all p < 0.05).

CONCLUSIONS

Neurodevelopmental scores for high-risk CLL survivors in infancy and toddlerhood are age appropriate. Neither fetal intervention nor the need for postnatal resection within the first month of life increases the risk of delays. Surrogate markers of a complicated neonatal course are predictive of adverse outcome.

Cognition and behaviour in children with congenital abdominal wall defects

AIM

To characterise neurodevelopment at age two years and cognition and behaviour at age five years in children born with abdominal wall defects (gastroschisis or exomphalos).

STUDY DESIGN

Participants were treated as neonates for gastroschisis or exomphalos and invited for routine clinical follow-up at ages two and five years. Thirty-nine two year-olds and 20 five year-olds with gastroschisis and 20 two year-olds and 10 five year-olds with exomphalos returned for age-appropriate assessments of development (two years) and intellectual functioning (IQ), executive function, and behavioural problems. Results were compared with normative data from the tests and published data from local term-born children.

RESULTS

For both gastroschisis and exomphalos two year-olds, neurodevelopment was in line with the test normative data, but below the level of local normative data for all domains (effect sizes from -0.4 to -1.4 standard deviations). At five years, children with gastroschisis performed similarly to the normative mean for IQ but had high rates of various executive functioning problems on parent report (18-41% compared with 7% expected from norms). There was also a tendency for increased frequency of internalising problems (33% compared with normative expectation of 16%). Five year-olds with exomphalos also performed similarly to the normative mean for IQ and had low rates of executive and behavioural problems.

CONCLUSIONS

Survivors of gastroschisis and exomphalos may be at risk of poor neurodevelopment in toddlerhood, depending on the reference group, and children with gastroschisis may be particularly at risk for executive functioning difficulties despite an IQ within normal limits.

Neurodevelopmental outcomes at 5years of age in congenital diaphragmatic hernia

OBJECTIVE

To evaluate neurodevelopmental sequelae in congenital diaphragmatic hernia (CDH) children at 5years of age.

MATERIALS AND METHODS

The study cohort of 35 CDH patients was enrolled in our follow-up program between 06/2004 and 09/2014. The neurodevelopmental outcomes assessed at a median of 5years (range, 4-6) included cognition (Wechsler Preschool and Primary Scale of Intelligence [WPPSI], n=35), Visual-Motor-Integration (n=35), academic achievement (Woodcock-Johnson Tests of Achievement, n=25), and behavior problems (Child Behavior Check List [CBCL], n=26). Scores were grouped as average, borderline, or extremely low by SD intervals.

RESULTS

Although mean Full (93.9±19.4), Verbal (93.4±18.4), and Performance (95.2±20.9) IQ were within the expected range, significantly more CDH children had borderline (17%) and extremely low (17%) scores in at least one domain compared to normative cohorts (P<0.02). The Visual-Motor-Integration score was below population average (P<0.001). Academic achievement scores were similar to expected means for those children who were able to complete testing. CBCL scores for the emotionally reactive (23%) and pervasive developmental problems scales (27%) were more likely to be abnormal compared to normal population scores (P=0.02 and P=0.0003, respectively). Autism was diagnosed in 11%, which is significantly higher than the general population (P<0.01). Univariate analysis suggests that prolonged NICU stay, prolonged intubation, tracheostomy placement, pulmonary hypertension, autism, hearing impairment, and developmental delays identified during infancy are associated with worse cognitive outcomes (P<0.05).

CONCLUSION

The majority of CDH children have neurodevelopmental outcomes within the average range at 5years of age. However, rates of borderline and extremely low IQ scores are significantly higher than in the general population. CDH survivors are also at increased risk for developing symptoms of emotionally reactive and pervasive developmental problems. Risk of autism is significantly elevated. Disease severity and early neurological dysfunction appear to be predictive of longer-term impairments.

Management of giant omphaloceles: A systematic review of methods of staged surgical vs. nonoperative delayed closure

PURPOSE

Despite the numerous methods of closure for giant omphaloceles, uncertainty persists regarding the most effective option. Our purpose was to review the literature to clarify the current methods being used and to determine superiority of either staged surgical procedures or nonoperative delayed closure in order to recommend a standard of care for the management of the giant omphalocele.

METHODS

Our initial database search resulted in 378 articles. After de-duplification and review, we requested 32 articles relevant to our topic that partially met our inclusion criteria. We found that 14 articles met our criteria; these 14 studies were included in our analysis. 10 studies met the inclusion criteria for nonoperative delayed closure, and 4 studies met the inclusion criteria for staged surgical management.

RESULTS

Numerous methods for managing giant omphaloceles have been described. Many studies use topical therapy secondarily to failed surgical management. Primary nonoperative delayed management had a cumulative mortality of 21.8% vs. 23.4% in the staged surgical group. Time to initiation of full enteric feedings was lower in the nonoperative delayed group at 14.6days vs 23.5days.

CONCLUSION

Despite advances in medical and surgical therapies, giant omphaloceles are still associated with a high mortality rate and numerous morbidities. In our analysis, we found that nonoperative delayed management with silver therapy was associated with lower mortality and shorter duration to full enteric feeding. We recommend that nonoperative delayed management be utilized as the primary therapy for the newborn with a giant omphalocele.
