To identify, in fetuses with a congenital lung malformation (CLM), prenatal predictors of the need for postnatal respiratory support and the need for surgery by calculating the CLM volume ratio (CVR), and to evaluate the concordance between the prenatal appearance and the postnatal type of CLM.This was an analysis of prenatal, perinatal and postnatal data from fetuses diagnosed with a CLM at the Erasmus University Medical Center - Sophia Children's Hospital in Rotterdam, The Netherlands, between January 2007 and December 2016. For all included fetuses, CVR was measured retrospectively on stored ultrasound images obtained at 18 + 1 to 24 + 6 weeks (US1), 25 + 0 to 29 + 6 weeks (US2) and/or 30 + 0 to 35 + 6 weeks' gestation (US3). Postnatal diagnosis of CLM was based on computed tomography or histology. Primary outcomes were the need for respiratory support within 24 h and surgery within 2 years after birth.Of the 80 fetuses with a CLM included in this study, 14 (18%) required respiratory support on the first postnatal day, and 17 (21%) required surgery within 2 years. Only the CVR at US2 was predictive of the need for respiratory support, with a cut-off value of 0.39. Four of 16 (25%) fetuses which showed full regression of the CLM prenatally required respiratory support within 24 h after birth. The CVR at US1, US2 and US3 was predictive of surgery within 2 years. Overall, the prenatal appearance of the CLM showed low concordance with the postnatal type. Prenatally suspected microcystic congenital pulmonary airway malformation (CPAM) was shown on computed tomography after birth to be congenital lobar overinflation in 15/35 (43%) cases. Respiratory support within 24 h after birth and surgical resection within 28 days after birth were needed in all cases of macrocystic CPAM.CVR can predict the need for respiratory support within 24 h after birth and for surgery within 2 years. Regression of a CLM prenatally does not rule out respiratory problems after birth. © 2020 The Authors.

Introduction To date, no consensus has been reached on the optimal management of congenital lung abnormalities, and factors predicting postnatal outcome have not been identified. We developed an objective quantitative computed tomography (CT) scoring method, and assessed its value for clinical decision‐making. Methods Volumetric CT‐scans of all patients born with a congenital lung abnormality between January 1999 and 2018 were assessed. Lung disease was quantified using the newly‐developed congenital lung abnormality quantification (CLAQ) scoring method. In 20 equidistant axial slices, cells of a square grid were scored according to the abnormality within. The scored CT parameters were used to predict development of symptoms, and SD scores for spirometry and exercise tolerance (Bruce treadmill test) at 8 years of age. Results CT‐scans of 124 patients with a median age of 5 months were scored. Clinical diagnoses included congenital pulmonary airway malformation (49%), bronchopulmonary sequestration (27%), congenital lobar overinflation (22%), and bronchogenic cyst (1%). Forty‐four patients (35%) developed symptoms requiring surgery of whom 28 (22%) patients became symptomatic before a CT‐scan was scheduled. Lesional hyperdensity was found as an important predictor of symptom development and decreased exercise tolerance. Using receiver operating characteristic analysis, an optimal cut‐off value for developing symptoms was found at 18% total disease. Conclusion CT‐quantification of congenital lung abnormalities using the CLAQ method is an objective and reproducible system to describe congenital lung abnormalities on chest CT. The risk for developing symptoms may increase when more than a single lung lobe is affected.

Objective To determine whether complex gastroschisis (ie, intestinal atresia, perforation, necrosis, or volvulus) can prenatally be distinguished from simple gastroschisis by fetal stomach volume and stomach‐bladder distance, using three‐dimensional (3D) ultrasound. Methods This multicenter prospective cohort study was conducted in the Netherlands between 2010 and 2015. Of seven university medical centers, we included the four centers that performed longitudinal 3D ultrasound measurements at a regular basis. We calculated stomach volumes (n = 223) using Sonography‐based Automated Volume Count. The shortest stomach‐bladder distance (n = 241) was determined using multiplanar visualization of the volume datasets. We used linear mixed modelling to evaluate the effect of gestational age and type of gastroschisis (simple or complex) on fetal stomach volume and stomach‐bladder distance. Results We included 79 affected fetuses. Sixty‐six (84%) had been assessed with 3D ultrasound at least once; 64 of these 66 were liveborn, nine (14%) had complex gastroschisis. With advancing gestational age, stomach volume significantly increased, and stomach‐bladder distance decreased (both P, What's already known about this topic? Infants with complex gastroschisis have a higher risk of morbidity than those with simple gastroschisis.Many attempts have been made to prenatally predict complex gastroschisis, using two‐dimensional ultrasound parameters. What does this study add? This longitudinal prospective multicenter study is the first to evaluate the possible benefit of the use of three‐dimensional ultrasound in fetuses with gastroschisis.Fetal stomach volume and stomach‐bladder distance, measured during pregnancy using three‐dimensional ultrasound, cannot predict complex gastroschisis.

ObjectiveWe aimed to identify gestational-age corrected prenatal ultrasound markers of complex gastroschisis, and to compare physical growth and neurodevelopment between children with simple and complex gastroschisis.DesignWe included prenatally diagnosed gastroschisis patients from 2000 to 2012 who joined our longitudinal follow-up programme. Associations between complex gastroschisis and prenatal ultrasound markers collected at 30 weeks’ gestation and prior to delivery were tested using logistic regression. Physical growth (SD scores (SDS)), mental and psychomotor developmental index (MDI, PDI; Bayley Scales of Infant Development) were recorded at 12 and 24 months. Data were analysed using general linear models and compared with population norms.ResultsData of 61 children were analysed (82% of eligible cases). Extra-abdominal bowel dilatation at 30 weeks’ gestation was significantly associated with complex gastroschisis (OR (95% CI): 5.00 (1.09 to 22.98)), with a high negative (88%) but low positive (40%) predictive value. The mean (95% CI) height SDS at 12 months (−0.46 (–0.82 to –0.11)), and weight SDS at 12 and 24 months (−0.45 (–0.85 to –0.05), and −0.44 (−0.87 to –0.01), respectively) fell significantly below 0 SDS. MDI and PDI were significantly below 100 at 24 months; 93 (88 to 99) and 83 (78 to 87), respectively). Children with complex gastroschisis had a significantly lower PDI (76 (68 to 84)) than those with simple gastroschisis (94 (90 to 97), pConclusionsPrenatal ultrasound markers could not reliably distinguish between simple and complex gastroschisis. Children with complex gastroschisis may be at increased risk for delayed psychomotor development; they should be monitored more closely, and offered timely intervention.

Objective To determine the predictive value of the fetal omphalocele circumference/abdominal circumference (OC/AC) ratio for type of surgical closure and survival and to describe the trajectory of OC/AC ratio throughout gestation. Methods This cohort study included all live‐born infants prenatally diagnosed with an omphalocele in our tertiary centre (2000–2017) with an intention to treat. The OC/AC ratio and liver position were determined using 2D ultrasound at three periods during gestation (11–16, 17–26, and/or 30–38 weeks). Primary outcome was type of closure; secondary outcome was survival. In the secondary analyses, the predictive value of the OC/AC‐ratio trend for type of closure and survival was assessed. Results Primary closure was performed in 37/63 (59%) infants, and 54/63 (86%) survived. The OC/AC ratio was predictive for type of closure and survival in all periods. Optimal cut‐off values for predicting closure decreased throughout gestation from 0.69 (11–16 weeks) to 0.63 (30–38 weeks). Repeated OC/AC‐ratio measurements were available in 33 (73%) fetuses. The trend of the OC/AC ratio throughout gestation was not significantly associated with type of closure. All infants without liver herniation underwent primary closure. Conclusion Type of omphalocele surgical closure and survival can be predicted prenatally on the basis of the OC/AC ratio and liver herniation independent of associated anomalies. Learning objective The reader will be able to use the OC/AC ratio throughout gestation in all omphalocele cases for prediction of type of closure and survival and thus patient counselling., What's already known about this topic? In fetuses with an isolated omphalocele, the OC/AC ratio is less than 24 weeks; gestation is of predictive value for postnatal type of closure. What does this study add? The OC/AC ratio is predictive for type of surgical closure and survival in all fetuses with an omphalocele.This report is the first concerning the trend of the OC/AC ratio throughout gestation.The OC/AC ratio best predicts type of closure and survival in the third trimester of pregnancy.

Children with gastroschisis are at high risk of morbidity in early life, which could affect long-term outcomes. We determined parent-reported outcomes in school-aged children born in 2000–2012, using paper questionnaires. Parent-perceived child vulnerability and motor function were compared with the Dutch reference data; parent-rated data on cognition, health status, quality of life, and behavior were compared with those of controls matched for age, gender, and maternal education level. Of 77 eligible participants, 31 (40%) returned the questionnaires. Parent-reported motor function was normal in 23 (74%) children. Total scores on health status, quality of life, and behavior did not differ significantly from those of matched controls. Children with gastroschisis had lower scores on cognition (median (interquartile range); 109 (87–127)) than their matched controls (124 (113–140); p = 0.04). Neonatal intestinal failure and increased parent-perceived vulnerability were associated with lower scores on cognition (β − 25.66 (95% confidence interval − 49.41, − 1.91); − 2.76 (− 5.27, − 0.25), respectively). Conclusion: Parent-reported outcomes of school-aged children with gastroschisis were mainly reassuring. Clinicians and parents should be aware of the higher risk of cognitive problems, especially in those with neonatal intestinal failure or increased parent-perceived vulnerability. We recommend multidisciplinary follow-up at school age of children with gastroschisis and neonatal intestinal failure. What is Known: • Many infants with gastroschisis experience morbidity in early life.• Data on developmental outcomes and daily functioning in children with gastroschisis beyond the age of 5 years are scarce and conflicting. What is New: • Parents of school-aged children treated for gastroschisis report normal motor function, health status, quality of life, and behavior.• Children with gastroschisis, especially those with intestinal failure, may be at risk for cognitive problems at school age. Parents who reported their child as being more vulnerable also reported more cognitive problems at school age.

ObjectivesTo 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.DesignWe 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.ResultsWe 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).ConclusionsThe 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.

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.
