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.
Prenatal 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 improve counseling on congenital lung malformations (CLM) by describing long‐term outcomes of children either operated on or managed by observation.
Study design
We analyzed lung function (spirometry), exercise tolerance (Bruce treadmill), and physical growth of 8‐year‐old children with CLM who participated in our longitudinal prospective follow‐up program. The data are shown as median standard deviation scores (SDS) with IQR, or estimated marginal means (95% CI) on the basis of general linear models.
Results
Twenty‐nine (48%) of the 61 children had required surgery at a median age of 108 (IQR: 8‐828) days, and 32 (52%) were managed by observation. In the surgery group, all lung function measurements (except for forced vital capacity [FVC]) were significantly below 0 SDS, with median FEV1 −1.07 (IQR: −1.70 to −0.56), FEV1/FVC −1.49 (−2.62 to −0.33), and FEF25%‐75% −1.95 (−2.57 to −0.63) (all P < 0.001). Children in the observation group had normal FEV1 and FVC, whereas FEV1/FVC (−0.81 (−1.65 to −0.14)) and FEF25%‐75% (−1.14 (−1.71 to −0.22)) were significantly below 0 SDS (both P < 0.001). Mean exercise tolerance was significantly below 0 SDS in both groups (observation: −0.85 (95% CI: −1.30 to −0.41); surgery: −1.25 (−1.69 to −0.80)); eight (28%) children in the observation group and ten (40%) in the surgery group scored <−1 SDS. Physical growth was normal in both groups.
Conclusion
Children with CLM may be at risk for reduced lung function and exercise tolerance, especially those who required surgery. As little pulmonary morbidity was found in children with asymptomatic CLM, this study supports a watchful waiting approach in this group.
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 cutoff 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
