[PMID: 38086256 DOI: 10.1016/j.jss.2023.11.048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 06/23/2023] [Accepted: 11/16/2023] [Indexed: 02/25/2024]
Abstract
INTRODUCTION Congenital lung malformations (CLMs) have a variable natural history. Larger lesions with CLM volume ratio (CVR) ≥ 1.6 are associated with hydrops and fetal mortality. The purpose of this study is to describe the management and outcomes of high-risk (CVR ≥ 1.6) CLM patients. METHODS A retrospective cohort study was performed for all fetuses evaluated between May 2015 and May 2022. Demographics, prenatal imaging factors, prenatal and postnatal treatment, and outcomes were collected. Descriptive statistics were used to compare the cohorts. RESULTS Of 149 fetal CLM patients referred to our fetal center, 21/149 (14%) had CVR ≥ 1.6. One CLM patient had intrauterine fetal demise, and 2 patients were lost to follow-up. Of the remaining 18 patients, 11/18 (67%) received maternal steroids. Seven out of 18 patients (39%) underwent resection at the time of delivery with 1/7 (14%) undergoing exutero intrapartum treatment (EXIT)-to-resection, 5/7 (71%) undergoing EXIT-to-exteriorization-to-resection, and 1/7 (14%) undergoing a coordinated delivery to resection; among those undergoing resection, there were 2 fatalities (28.5%). Seven out of 18 (39%) patients required urgent neonatal open lobectomies, and the remaining 4/18 (22%) patients underwent elective thoracoscopic lobectomies with no mortality. CONCLUSIONS The natural history and outcomes of severe CLM patients remain highly variable. The EXIT-to-exteriorization-to-resection procedure may be a safe and effective approach for a subset of CLM patients with persistent symptoms of mass effect and severe mediastinal shift due to the observed decreased operative time requiring placental support observed in our study.

Abstract
Congenital lung malformations (CLMs) are rare developmental anomalies of the lung, including congenital pulmonary airway malformations (CPAM), bronchopulmonary sequestration, congenital lobar overinflation, bronchogenic cyst and isolated congenital bronchial atresia. CLMs occur in 4 out of 10,000 live births. Postnatal presentation ranges from an asymptomatic infant to respiratory failure. CLMs are typically diagnosed with antenatal ultrasonography and confirmed by chest CT angiography in the first few months of life. Although surgical treatment is the gold standard for symptomatic CLMs, a consensus on asymptomatic cases has not been reached. Resection, either thoracoscopically or through thoracotomy, minimizes the risk of local morbidity, including recurrent infections and pneumothorax, and avoids the risk of malignancies that have been associated with CPAM, bronchopulmonary sequestration and bronchogenic cyst. However, some surgeons suggest expectant management as the incidence of adverse outcomes, including malignancy, remains unknown. In either case, a planned follow-up and a proper transition to adult care are needed. The biological mechanisms through which some CLMs may trigger malignant transformation are under investigation. KRAS has already been confirmed to be somatically mutated in CPAM and other genetic susceptibilities linked to tumour development have been explored. By summarizing current progress in CLM diagnosis, management and molecular understanding we hope to highlight open questions that require urgent attention.

Serial lung mass volume ratios as prognostic indicators of neonatal respiratory morbidity in fetal pulmonary malformations. Am J Obstet Gynecol MFM 2023; 5:101128. [PMID: 37572880 DOI: 10.1016/j.ajogmf.2023.101128] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Revised: 08/02/2023] [Accepted: 08/05/2023] [Indexed: 08/14/2023]
Abstract
BACKGROUND Several studies have shown that the congenital pulmonary airway malformation volume ratio is a useful prognosticator of neonatal outcome in prenatally diagnosed lung lesions. However, there remains a lack of consensus on which congenital pulmonary airway malformation volume ratio values have the best predictive value because of operator dependence, inherent changes in lung lesion size throughout gestation, and the widespread use of maternal steroids. OBJECTIVE This study sought to determine the association between serial congenital pulmonary airway malformation volume ratio measurements and neonatal outcomes among fetuses with lung malformations. STUDY DESIGN This was a retrospective cohort study of fetuses with a prenatally diagnosed lung malformation managed at 2 major fetal centers from January 2010 to December 2021. Prenatal variables, including prospectively measured congenital pulmonary airway malformation volume ratio measurements (initial, maximum, and final), were analyzed. The results were correlated with 3 outcome measures, namely surgical resection before 30 days of life, a need for supplemental O2 at birth, and endotracheal intubation at birth. Statistical analyses were performed using receiver operating characteristic curve analyses, Welch 2 sample t tests, and multivariable logistic regressions (P<.05). RESULTS There were 123 fetuses with isolated lung lesions identified. Eight (6.5%) had hydrops. The mean initial congenital pulmonary airway malformation volume ratio was 0.67±0.61 cm2 at 22.9±3.9 weeks' gestation. The mean maximum congenital pulmonary airway malformation volume ratio was 1.08 ± 0.94 cm2 at 27.0 ± 4.0 weeks' gestation. The mean final congenital pulmonary airway malformation volume ratio was 0.58±0.60 cm2 at 33.2±4.1 weeks' gestation. At a mean gestational age at delivery of 38.3±2.6 weeks, 15 (12.2%) underwent neonatal lung resection for symptomatic disease. In a multivariable regression, all 3 congenital pulmonary airway malformation volume ratio measurements showed a significant correlation with neonatal lung resection (P<.001). Optimal congenital pulmonary airway malformation volume ratio cutoffs were established based on an initial congenital pulmonary airway malformation volume ratio of ≥0.8 cm2, maximum congenital pulmonary airway malformation volume ratio of ≥1.5 cm2, and a final congenital pulmonary airway malformation volume ratio of ≥1.3 cm2 with associated areas under the curve of 0.89, 0.97, and 0.93, respectively. The final congenital pulmonary airway malformation volume ratio had the highest specificity for predicting surgical lung resection in the early postnatal period. CONCLUSION Measuring congenital pulmonary airway malformation volume ratios throughout pregnancy in fetuses with pulmonary malformations has clinical value for prenatal counseling and planning care transition after delivery. Fetuses with a final congenital pulmonary airway malformation volume ratio of more than 1.3 cm2 are likely to require neonatal surgery and therefore should be delivered at tertiary care centers with a neonatal intensive care unit and pediatric surgical expertise.

Abstract
Congenital lung malformations (CLMs) are commonly diagnosed prenatal lesions with varied natural history. Prenatal diagnosis and monitoring help to guide fetal interventions, delivery planning, and need for urgent perinatal surgical interventions. All prenatally diagnosed CLMs should be evaluated postnatally, typically with cross-sectional imaging, because many lesions persist despite the appearance of complete 'regression' in utero. Management of CLMs in asymptomatic infants weighs the surgical and anesthetic risk of prophylactic resection against the risk of expectant management, including the possibility of infection, malignant degeneration, and more complicated surgical resection later with loss of compensatory lung growth.

Abstract
AIM The purpose of this study is to evaluate whether CPAM-volume ratio (CVR) can predict postnatal management (follow up for resolution and surgical treatment) in fetuses with fetal lung masses in the prenatal period. MATERIALS AND METHODS 44 patients who presented at our center with prenatally diagnosed CPAM (Congenital Pulmonary Airway Malformation) and BPS (Bronchopulmonary Sequestration) were analyzed. Obstetric history and outcomes, karyotype results, CVR, additional sonographic findings, characteristics of masses were recorded. CVR was calculated for all cases. İn the study we sought to identify a CVR threshold and did not use the thresholds classically used in the literature. RESULTS 20 fetal BPS and 24 CPAM cases were analyzed. After excluding 5 patients, 46% of the patients were diagnosed with BPS and 54% with CPAM. İn this study the cut off < 0,53 for CVR is taken, it predicts the no need for postnatal surgery with a sensitivity of 85% and a specificity of 88%. When we take the > 0,76 cut-off value for patients who will require emergency surgery within the first 10 days, it predicts the need for surgery with 90% sensitivity and 89% specificity. In addition, it was determined that all patients with mediastinal shift were operated. CONCLUSION We believe that the CVR value and the presence of mediastinal shift should be evaluated in all cases of CPAM and BPS for prediction of the surgery. Proper counseling about the prognosis could be given to the family in cases with mediastinal shift and CVR value above 0,76.

Abstract
Congenital lung malformations represent a spectrum of lesions, each with a distinct cause and tailored clinical approach. This article will focus on the following malformations: congenital pulmonary airway malformations, formally known as congenital cystic adenomatoid malformations, bronchopulmonary sequestration, congenital lobar emphysema, and bronchogenic cyst. Each of these malformations will be defined and examined from an embryologic, pathophysiologic, and clinical management perspective unique to that specific lesion. A review of current recommendations in both medical and surgical management of these lesions will be discussed as well as widely accepted treatment algorithms.

Abstract
BACKGROUND The natural history of congenital pulmonary airway malformations (CPAM) and bronchopulmonary sequestrations (BPS) is not fully understood, and the management of the newborn with an asymptomatic lesion is a controversial issue. We aimed to study the natural history and outcome of CPAM/BPS at our institution with a policy of watchful waiting, and to investigate if any prognostic factors in the pre- and/or postnatal- period may predict the need for surgery. MATERIAL AND METHODS A retrospective review study was conducted of children prenatally diagnosed with CPAM and/or BPS during the 18-year period, from 2002 to 2020. Data from the pre and postnatal period was collected and analysed. RESULTS Sixty- six patients with prenatally observed lung lesions were entered in the study, with an overall survival rate of 94%. Fifty-six percent of the lesions decreased in size during gestation. Thirty-one percent had surgery and 69% could be managed conservatively with a median follow-up of 4 years. Nineteen percent developed symptoms after the neonatal period. Children with a presence of mediastinal shift on postnatal imaging (p = 0.003), with a high CVR (p = 0.005) and a large lesion size during gestation (p = 0.014) were significantly more likely to require surgery. CONCLUSION Prenatal regression is common among prenatally diagnosed CPAM/BPS and the majority of children that are asymptomatic beyond the neonatal period will remain asymptomatic throughout their childhood. Future analysis with a longer follow-up might give new insights in order to identify children at risk of developing symptoms. LEVEL OF EVIDENCE III.

Abstract
PURPOSE Congenital lung malformation (CLM) volume ratio (CVR) of ≥1.1 has been shown to be highly predictive of the need for urgent, perinatal surgical intervention. The purpose of this study was to utilize this information to propose a delivery planning and clinical management algorithm based on this threshold. METHODS A retrospective cohort study was performed for all fetuses evaluated at our fetal center between 5/2015 and 11/2020. Demographics, ultrasound findings, late gestation CVR (≥27 weeks gestational age), prenatal and postnatal treatment, and outcomes were analyzed with nonparametric univariate analysis based on late gestation CVR of 1.1. Receiver operating characteristic curve analysis was performed to evaluate association between late gestation CVR, hydrops, need for fetal intervention, and need for urgent perinatal surgery. RESULTS Of the 90 CLMs referred to our fetal center, 65 had late gestation CVR with a majority <1.1 (47/65, 72%). All patients with late gestation CVR ≥ 1.1 were managed with resection (18/18) with most resections requiring fetal intervention or urgent neonatal resection (13/18). Late gestation CVR < 1.1 were managed with elective resection (36/47, 77%) or non-operative observation (11/47, 23%). Late gestation CVR ≥ 1.1 had 100% sensitivity and NPV for hydrops, need for fetal intervention, and need for urgent perinatal surgery. CONCLUSION CLM with CVR ≥ 1.1 were associated with urgent perinatal surgical intervention and expectant mothers should plan for delivery at centers equipped to manage neonatal resuscitation and potential urgent neonatal resection. Conversely, CLM with CVR < 1.1 may be safe to deliver at patient hospital of choice.

Abstract
INTRODUCTION Pulmonary hypertension is a major determinant of postnatal survival in infants with a congenital diaphragmatic hernia (CDH). The current care during the perinatal stabilisation period in these infants might contribute to the development of pulmonary hypertension after birth-in particular umbilical cord clamping before lung aeration. An ovine model of diaphragmatic hernia demonstrated that cord clamping after lung aeration, called physiological-based cord clamping (PBCC), avoided the initial high pressures in the lung vasculature while maintaining adequate blood flow, thereby avoiding vascular remodelling and aggravation of pulmonary hypertension. We aim to investigate if the implementation of PBCC in the perinatal stabilisation period of infants born with a CDH could reduce the incidence of pulmonary hypertension in the first 24 hours after birth. METHODS AND ANALYSIS We will perform a multicentre, randomised controlled trial in infants with an isolated left-sided CDH, born at ≥35.0 weeks. Before birth, infants will be randomised to either PBCC or immediate cord clamping, stratified by treatment centre and severity of pulmonary hypoplasia on antenatal ultrasound. PBCC will be performed using a purpose-built resuscitation trolley. Cord clamping will be performed when the infant is considered respiratory stable, defined as a heart rate >100 bpm, preductal oxygen saturation >85%, while using a fraction of inspired oxygen of <0.5. The primary outcome is pulmonary hypertension diagnosed in the first 24 hours after birth, based on clinical and echocardiographic parameters. Secondary outcomes include neonatal as well as maternal outcomes. ETHICS AND DISSEMINATION Central ethical approval was obtained from the Medical Ethical Committee of the Erasmus MC, Rotterdam, The Netherlands (METC 2019-0414). Local ethical approval will be obtained by submitting the protocol to the regulatory bodies and local institutional review boards. TRIAL REGISTRATION NUMBER NCT04373902.

Abstract
Pleuropulmonary blastoma (PPB) is a very rare pediatric lung disease. It can progress from abnormal epithelial cysts to an aggressive sarcoma with poor survival. PPB is difficult to diagnose as it can be confounded with other cystic lung disorders, such as congenital pulmonary airway malformation (CPAM). PPB is associated with mutations in DICER1 that perturb the microRNA (miRNA) profile in lung. How DICER1 and miRNAs act during PPB pathogenesis remains unsolved. Lung epithelial deletion of the Yin Yang1 (Yy1) gene in mice causes a phenotype mimicking the cystic form of PPB and affects the expression of key regulators of lung development. Similar changes in expression were observed in PPB but not in CPAM lung biopsies, revealing a distinctive PPB molecular signature. Deregulation of molecules promoting epithelial-mesenchymal transition (EMT) was detected in PPB specimens, suggesting that EMT might participate in tumor progression. Changes in miRNA expression also occurred in PPB lung biopsies. miR-125a-3p, a candidate to regulate YY1 expression and lung branching, was abnormally highly expressed in PPB samples. Together, these findings support the concept that reduced expression of YY1, due to the abnormal miRNA profile resulting from DICER1 mutations, contributes to PPB development via its impact on the expression of key lung developmental genes.This article has an associated First Person interview with the joint first authors of the paper.

Abstract
BACKGROUND Congenital-pulmonary-airway-malformation (CPAM) and bronchopulmonary-sequestration (BPS) are rare conditions. The objective of this study was to describe the sonographic characteristics and prenatal course of fetal lung mass. METHODS A retrospective study on 20 pregnancies with CPAM and BPS diagnosed during 2018-2018 was performed. Data evaluated included gestational age (GA) at diagnosis, size of lesion, CPAM-volume-ratio (CVR), associated sonographic findings and pregnancy outcome. RESULTS Fourteen cases of CPAM and six cases of BPS were evaluated. The average GA at diagnosis was 22 weeks'-gestation (range 17-26). 66% were macrocystic-multicystic. Five cases of BPS (71.4%) had other structural anomalies. None of the fetuses with CPAM had additional anomalies. Four pregnancies (20%) underwent termination due to severe hydrops fetalis. Two cases of CPAM (15%) had spontaneous resolution by 30 week's-gestation; three cases (20%) continued to grow during pregnancy and all the rest reached their largest size at 25-28 week's-gestation. Most cases delivered at term (average 37.6 range 32.2-41.4). Two children had lobectomy at 11 and 12 months of life. CONCLUSIONS Careful follow-up during pregnancy may result in term delivery of adequate-for-gestational-age newborns, with no need for admission to the NICU, with only 10% need for lobectomy during the first year of life.

Abstract
BACKGROUND Congenital lung malformations (CLMs) have a variable natural history: some patients require urgent perinatal surgical intervention (UPSI) and others remain asymptomatic. These lesions have potential growth until 26-28 wk gestation. CLM volume ratio (CVR) has been shown to predict the risk of hydrops in CLMs. However, no criteria exist to delineate lesions requiring urgent surgical intervention in the perinatal period. Our goal was to determine prenatal diagnostic features that predict the need for UPSI in patients diagnosed with CLM. METHODS Records and imaging features of all fetuses evaluated by our fetal center between May 2015 and December 2018 were retrospectively reviewed. Data included demographics, fetal ultrasound and magnetic resonance imaging, CVR, surgical treatment, and outcome. Features were analyzed for their ability to predict the need for UPSI. RESULTS Sixty-four patients were referred for CLM, with 48 patients serially followed. Nine (18.8%) patients were followed nonoperatively, 35 (72.9%) underwent resection, and four (8.3%) were lost to follow-up. Of the patients who underwent resection, 24 (68.5%) were electively resected and 11 were urgently resected. Five (14.3%) patients underwent ex utero intrapartum treatment resection, and six (17.1%) were urgently resected for symptomatic CLM. There were no cases of UPSI with final CVR <1.1. Of the patients with final CVR 1.1-1.7, 43% required urgent resection. CVR ≥1.1 has 100% sensitivity and 87.8% specificity to predict patients requiring UPSI (area under the curve of 0.98). CONCLUSIONS A final CVR ≥1.1 is highly predictive for UPSI. Patients with a final CVR ≥1.1 should be referred for delivery at centers with pediatric surgeons equipped for potential UPSI for CLM.

ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2019; 54:759-766.

Abstract
OBJECTIVES The congenital lung malformation volume ratio (CVR) is a prenatal ultrasound measurement that parameterizes congenital lung malformation (CLM) size. The aims of this study were to use serial measurements to create estimated growth curves of fetal CVR for asymptomatic and symptomatic neonates with CLM and to investigate whether a discriminant prognostic model based on these measurements could predict accurately which fetuses with CLM will require invasive respiratory support at delivery and should therefore be delivered at a tertiary-care facility. METHODS This was a retrospective study of fetuses diagnosed prenatally with CLM at three tertiary-care children's hospitals between 2009 and 2016. Those with two or more sonographic measurements of CVR were included. Serial fetal CVR measurements were used to create estimated growth curves for neonates with and those without respiratory symptoms at delivery, defined as requiring invasive respiratory support for the first 24 h after delivery. A discriminant model based on serial CVR measurements was used to calculate the dynamic probability of the need for invasive respiratory support. The performance of this model overall and in preterm and term neonates was compared with those using maximum CVR thresholds of 1.0 and 1.6. RESULTS Of the 147 neonates meeting the inclusion criteria, 16 (10.9%) required postnatal invasive respiratory support. The estimated CVR growth curve models showed different growth trajectories for asymptomatic and symptomatic neonates, with significantly higher CVR in symptomatic neonates, and values peaking late in the second trimester at around 25 weeks' gestation in asymptomatic neonates. All prognostic methods had high accuracy for the prediction of the need for invasive respiratory support in term neonates, but the discriminant model had the best performance overall (area under the receiver-operating characteristics curve (AUC) = 0.88) and in the preterm population (AUC = 0.85). CONCLUSIONS The estimated CVR growth curves showed different growth patterns in asymptomatic and symptomatic neonates with CLM. The dynamic discriminant model performed well overall and particularly in neonates that were carried to term. Development of an externally validated clinical tool based on this analysis could be useful in determining the site of delivery for fetuses with CLM. Copyright © 2019 ISUOG.

Fetal Diagn Ther 2019; 47:171-181.

Abstract
Although relatively uncommon, the incidence of fetal echogenic lung lesions - a heterogeneous group of anomalies that includes congenital pulmonary airway malformations (CPAM) and bronchopulmonary sequestrations (BPS) - has increased recently. Two decades ago, the CPAM-volume ratio (CVR) was first described as a tool to predict the development of hydrops, with this outcome found to be unlikely in fetuses with CVRs of ≤1.6 cm2. Since then, no clear international consensus has evolved as to the optimal CVR thresholds for the prediction of fetal/neonatal outcomes. This systematic review aimed to assess all original research studies that reported on the predictive utility of the CVR. Potentially relevant papers were identified through searching for citations of the paper that originally described the CVR, in addition to keyword searches of electronic databases. Fifty-two original research papers were included in the final review. Of these, 34 used the CVR for descriptive purposes only, 5 assessed the validity of established thresholds in different populations, and 13 proposed new thresholds. The evidence identified in this review would suggest that a threshold much lower than 1.6 cm2 is likely to be of greater utility in most populations for many outcomes of perinatal relevance. For neonatal outcomes (mostly respiratory compromise at birth), a CVR on the initial ultrasound scan ranging from 0.5 to 1.0 cm2 appears to have the greatest predictive value. Although a number of studies concurred that 1.6 cm2 was a useful threshold for the prediction of hydrops, many others were unable to assess this due to the rarity of this complication. For this reason, thresholds as low as 0.4 cm2 may be more useful for the prediction of a broader range of fetal concerns, including mediastinal shift and fluid collections. Further large-scale studies are required to determine the true utility of this well-established index.

Abstract
INTRODUCTION The purpose of this study was to evaluate short-term respiratory outcomes in neonates with symptomatic congenital lung malformations (CLM). METHODS Consecutive newborns who underwent surgical resection of a CLM were retrospectively reviewed. Demographic, prenatal, and outcomes data were analyzed as appropriate (p < 0.05). RESULTS Twenty-one neonates were managed at a median gestational age of 36.2 weeks [interquartile range (IQR), 33.8-39.0]. Endotracheal intubation was required in 14 (66.7%) for a median of 7.5 days [interquartile range (IQR), 3.0-25.8]. Three (14.3%) children underwent ex utero intrapartum treatment-to-resection, and another 14 (66.7%) had neonatal lung resections performed at a median age of 2.0 days (IQR, 0.08-19.5 days). Excluding one patient who received comfort care at birth, all neonates survived to hospital discharge with a median length of hospitalization of 36.5 days (IQR, 23.8-56.5). More than one-quarter were discharged on supplemental oxygen by nasal cannula. Based on a median follow up of 35.5 months (IQR, 19.0-80.8), CLM-related morbidity was still evident in 55.0%. CONCLUSION Our study suggests a high incidence of complications and chronic respiratory morbidity after neonatal lung resection for symptomatic CLMs. These data highlight the need to provide realistic expectations in perinatal counseling discussions with families and the importance of coordinating appropriate multidisciplinary follow up for these children.

Abstract
BACKGROUND Pediatric surgeons frequently offer prenatal consultation for congenital pulmonary airway malformation (CPAM) and congenital diaphragmatic hernia (CDH); however, there is no evidence-based consensus to guide prenatal decision making and counseling for these conditions. Eliciting feedback from experts is integral to defining best practice regarding prenatal counseling and intervention. METHODS A Delphi consensus process was undertaken using a panel of pediatric surgeons identified as experts in fetal therapy to address current limitations. Areas of discrepancy in the literature on CPAM and CDH were identified and used to generate a list of content and intervention questions. Experts were invited to participate in an online Delphi survey. Items that did not reach first-round consensus were broken down into additional questions, and consensus was achieved in the second round. RESULTS Fifty-four surgeons (69%) responded to at least one of the two survey rounds. During round one, consensus was reached on 54 of 89 survey questions (61%), and 45 new questions were developed. During round two, consensus was reached on 53 of 60 survey questions (88%). CONCLUSIONS We determined expert consensus to establish guidelines regarding perinatal management of CPAM and CDH. Our results can help educate pediatric surgeons participating in perinatal care of these patients. LEVEL OF EVIDENCE V.

Abstract
Introduction Congenital cystic adenomatoid malformation (CCAM) is a rare anomaly. The mechanisms and the time at which the abnormality develops are still unclear. The malformation is characterized by the presence of single large or multiple but smaller cysts. Aim To present the experience of our medical centre, the Polish Mother’s Memorial Hospital – Research Institute. Material and methods We analysed the medical records of 32 neonates hospitalized in 2008–2017 at the Department of Paediatric Surgery and Urology ICZMP due to pre- or postnatally diagnosed congenital cystic adenomatoid malformation. Results In 2008–2017 32 children were hospitalized at our department due to prenatally diagnosed CCAM. An intrauterine procedure of thoracoamniotic shunting was performed in 13 fetuses. All newborns had chest computed tomography. Surgery had been performed in 21 children. Histopathological analysis of specimens prepared from the resected lung tissue confirmed type 1 CCAM in 4 cases, type 2 CCAM in 11 cases and type 3 CCAM in 1 case. Four patients were diagnosed with a bronchogenic cyst and one with extralobar pulmonary sequestration. Conclusions Postnatal management of CCAM depends on the clinical status of the newborn. Newborns without clinical symptoms require radiological diagnostics to confirm the presence of malformation. Surgical treatment is recommended before the age of 10 months. Resection of the malformed lung fragment in patients with CCAM is the first-line treatment. It should be emphasized that despite the tremendous advances in diagnostic imaging, the final diagnosis of CCAM is made based on histopathological findings.

Abstract
BACKGROUND The differential diagnosis for primary lung masses in neonates includes a variety of developmental abnormalities; it also consists of the much rarer congenital primary lung tumors: cystic pleuropulmonary blastoma (cystic PPB), fetal lung interstitial tumor (FLIT), congenital peribronchial myofibroblastic tumor (CPMT), and congenital fibrosarcoma. Radiologic differentiation between malformations and tumors is often very challenging. OBJECTIVE The objective was to establish distinctive features between developmental pulmonary abnormalities and primary lung tumors. MATERIALS AND METHODS We conducted a retrospective study of 135 congenital lung lesions at a university mother and child center over a period of 10 years (2005-2015). During this time, we noted four tumors (two cystic PPBs and two FLITs) and 131 malformations. We recorded the following parameters: timing of conspicuity in utero (mid-second trimester, third trimester, or not seen prenatally), presence of symptoms at birth, prenatal and perinatal radiologic findings, and either histological diagnoses by pathology or follow-up imaging in non-operated cases. RESULTS All lesions except the four tumors were detected during mid-second-trimester ultrasound. In none of the tumors was any pulmonary abnormality found on the mid-second-trimester sonogram, contrary to the developmental pulmonary abnormalities. CONCLUSION The timing of conspicuity in utero appears to be a key feature for the differentiation between malformations and tumors. Lesions that were not visible at the mid-second-trimester ultrasound should be considered as tumor. A cystic lung lesion in the context of a normal mid-second-trimester ultrasound is highly suggestive of a cystic PPB. Differentiating the types of solid congenital lung tumors based upon imaging features is not yet feasible.

Abstract
BACKGROUND Video-assisted thoracic surgery (VATS) pulmonary resection in children is a technically demanding procedure that requires a relatively long learning period. This study aimed to evaluate the serial improvement of quality metrics according to case volume experience in pediatric VATS pulmonary resection of congenital lung malformation (CLM). Methods VATS anatomical resection in CLM was attempted in 200 consecutive patients. The learning curve for the operative time was modeled by cumulative sum analysis. Quality metrics were used to measure technical achievement and efficiency outcomes. Results The median operative time was 95 min. The median length of hospital stay and chest tube indwelling time was 4 and 2 days, respectively. The improvement of operation time was observed persistently until 200 cases. However, two cut-off points, the 50th case and 110th case, were identified in the learning curve for operative time, and the 110th case was the turning point for stable outcomes with short operation time. Significant reduction of length of hospital stay and chest tube indwelling time was observed after 50 cases (p = .002 and p = .021, respectively). The complication rate decreased but continued at a low rate for entire study period and the interval decrease was not statistically significant. Conversion rate decreased significantly (p = .001), and technically challenging procedures were performed more frequently in later cases. Conclusions Improvements of quality metrics in operation time, conversion rate, length of hospital stay, and chest tube indwelling time were observed in proportion to case volume. Minimum experience of 50 is necessary for stable outcomes of pediatric VATS pulmonary resection.

Abstract
Congenital cystic adenomatoid malformation is a rare, but well-known disease. It can be managed conservatively in patients without symptoms or require surgical removal when symptomatic. The surgical option of choice is en bloc resection of the affected lesion. We report an experience of life-threatening congenital cystic adenoid malformation in a low-birth-weight (1,590 g) premature neonate who was successfully treated with a lobectomy of the lung.

Abstract
OBJECTIVE To describe antenatal findings and evaluate prenatal risk parameters for adverse outcome or need for intervention in fetuses with congenital pulmonary airway malformation (CPAM). METHODS In our retrospective study all fetuses with a prenatal diagnosis of CPAM detected in our tertiary referral center between 2002 and 2013 were analyzed. Sonographic findings were noted and measurements of mass-to-thorax-ratio (MTR), congenital pulmonary airway malformation volume-ratio (CVR) and observed to expected lung-to head-ratio (o/e LHR) were conducted and correlated to fetal or neonatal morbidity and mortality and/or need for prenatal intervention. RESULTS 67 fetuses with CPAM were included in the study. Hydropic fetuses were observed in 16.4% (11/67) of cases, prenatal intervention was undertaken in 9 cases; 7 pregnancies were terminated. The survival rate of non-hydropic fetuses with conservatively managed CPAM was 98.0% (50/51), the survival rate for hydropic fetuses with intention to treat was 42.9% (3/7). 10 (18.2%) children needed respiratory assistance. Fetuses with a CVR of <0.91 were significantly less likely to experience adverse outcome or need for prenatal intervention with sensitivity, specificity and positive/negative predictive value of 0.89, 0.71, 0.62 and 0.93, respectively. A MTR (mass-to-thorax-ratio) of < 0.51 had a positive predictive value of 0.54 and a negative predictive value of 0.96 of adverse events with a sensitivity of 0.95 and a specificity of 0.63. The negative predictive value for o/e LHR of 45% was 0.84 with sensitivity, specificity and positive predictive value of 0.73, 0.68 and 0.52, respectively. CONCLUSIONS The majority of cases with CPAM have a favorable outcome. MTR and CVR are able to identify fetuses at risk, the o/e LHR is less sensitive.

Abstract
PURPOSE Administration of maternal betamethasone (BMZ) is a therapeutic option for fetuses with large microcystic congenital lung lesions at risk for, or causing, hydrops. Not all fetuses respond to a single course of BMZ. We review our experience with the use of single and multiple courses of maternal BMZ for the management of these patients. METHODS A retrospective review of fetuses with congenital lung lesions managed with maternal BMZ from 2003 to 2014 was performed. RESULTS Forty-three patients were managed with prenatal steroids (28 single course, 15 multiple courses). Single course recipients demonstrated a reduction in lesion size and resolution of hydrops in 82% and 88% of patients respectively compared to 47% and 56% in recipients of multiple steroid courses. Survival of multiple course patients (86%) was comparable to that of single course patients (93%) and improved compared to non-treated historical controls. Multiple course recipients demonstrated an increased need for open fetal surgery and postnatal surgery at a younger age. CONCLUSION Fetuses who fail to respond to a single course of BMZ may benefit, as indicated by hydrops resolution and improved survival, from additional courses. However, failure to respond is indicative of a lesion which may require fetal or immediate neonatal resection.

Abstract
PURPOSE To describe a transabdominal, transuterine Seldinger-based percutaneous approach to create a shunt for treatment of fetal thoracic abnormalities. MATERIALS AND METHODS Five fetuses presented with nonimmune fetal hydrops secondary to fetal thoracic abnormalities causing severe mass effect. Under direct ultrasound guidance, an 18-gauge needle was used to access the malformation. Through a peel-away sheath, a customized pediatric transplant 4.5-F double J ureteral stent was advanced; the leading loop was placed in the fetal thorax, and the trailing end was left outside the fetal thorax within the amniotic cavity. RESULTS Seven thoracoamniotic shunts were successfully placed in five fetuses; one shunt was immediately replaced because of displacement during the procedure, and another shunt was not functioning at follow-up requiring insertion of a second shunt. All fetuses had successful decompression of the thoracic malformation, allowing lung reexpansion and resolution of hydrops. Three of five mothers had meaningful (> 7 d) prolongation of their pregnancies. All pregnancies were maintained to > 30 weeks (range, 30 weeks 1 d-37 weeks 2 d). There were no maternal complications. CONCLUSIONS A Seldinger-based percutaneous approach to draining fetal thoracic abnormalities is feasible and can allow for prolongation of pregnancy and antenatal lung development and ultimately result in fetal survival.

Abstract
Congenital cystic adenomatoid malformations (CCAM) of the lung are the most frequent congenital lung malformations. Their diagnosis is based on histological features. CCAM consist of bronchopulmonary cystic lesions which are classified according to the presence and cysts size. Type I CCAM are composed of large cysts (>2 cm) lined by a columnar pseudostratified epithelium. Type II CCAM contain multiple small cystic lesions (<1 cm) lined by a flattened cuboidal epithelium. Type III CCAM are more solid and contain immature structures resembling the pseudoglandular stage of lung development. Ultrasonography (US) allows early detection during the second trimester of pregnancy as cystic, and/or hyperechoic fetal lung lesions. Although most CCAM remain asymptomatic, CCAM can cause polyhydramnios or fetal hydrops, respiratory distress at birth, infections and pneumothoraces during infancy, and may give rise to malignancies. Serial US allow detection of complications, and planification of delivery. Complicated forms require an urgent treatment. In fetuses with a macrocystic life-threatening lesion, a thoraco-amniotic shunt can be placed. Microcystic compressive forms may respond to prenatal steroids. Post-natal symptomatic lesions require early surgery. The treatment of asymptomatic forms remains controversial. Some recommend a non-operative approach with a long-term clinical and radiological following, whereas other favour a preventive surgical excision. The origin of CCAM remains unknown. Recent advances suggest a transient and focal abnormality in lung development which may result from an airway obstruction. This article reviews the diagnosis, treatment, and pathophysiology of CCAM.

Abstract
OBJECTIVE The purpose of this study was to develop a simple and accurate approach for risk stratification of fetal lung lesions that are associated with respiratory compromise at birth. STUDY DESIGN We conducted a retrospective review of 64 prenatal lung lesions that were managed at a single fetal care referral center (2001-2011). Sonographic data were analyzed and correlated with perinatal outcomes. RESULTS Hydrops occurred in only 4 cases (6.3%). Among fetuses without hydrops, the congenital pulmonary airway malformation volume ratio (CVR) was the only variable that was associated significantly with respiratory compromise and the need for lung resection at birth (P < .01). Based on a maximum CVR >1.0, the sensitivity, specificity, positive predictive value, and negative predictive value for respiratory morbidity were 90%, 93%, 75%, and 98%, respectively. CONCLUSION Nonhydropic fetuses with a maximum CVR >1.0 are a subgroup of patients who are at increased risk for respiratory morbidity and the need for surgical intervention. These patients should be delivered at a tertiary care center with pediatric surgery expertise to ensure optimal clinical outcomes.

Abstract
Sonographic scan revealed a homogenously hyperechogenic lesion in the right fetal lung with microcystic pattern by a primigravid women at 22nd weeks of gestation. A large congenital pulmonary airway malformation (CPAM) was suspected with a lesion-to-lung ratio over 90%. The microcystic image of this thoracic anomaly was moderately visible on magnetic resonance imaging (MRI) at that early stage of the pregnancy. Fetopsy confirmed the diagnosis as a pure microcystic CPAM following termination of pregnancy. A controlled prospective study could be performed to compare ultrasound as a diagnostic modality to the MRI, focusing on volumetry, signal characteristics, and follow-up/regression of fetal pulmonary malformations.

Abstract
PURPOSE To identify prenatal diagnostic features that will help select fetuses with lung masses (LM) who may benefit from ex-utero intrapartum treatment (EXIT procedure) as the preferred mode of delivery. METHODS The CCAM-volume ratio (CVR), fetal treatment, and outcomes of all fetuses with LM evaluated between 2001 and 2011 were reviewed retrospectively. Fetuses with hydrops or CVR>1.6 were classified as high risk. Indications for fetal interventions included hydrops and heart failure, and indication for EXIT-to-resection was the finding of persistent mediastinal compression (PMC) near birth. RESULTS Of 110 fetuses evaluated for LM, 78 were classified as low-risk. No fetus in this group had PMC near birth and none required perinatal treatment. Of 32 high-risk fetuses, 8 developed heart failure of which 4 survived (3 following fetal surgery). Nine high-risk fetuses with no PMC near birth were asymptomatic postnatally and treated electively. Sixteen high-risk fetuses had PMC near birth. All 9 babies with PMC treated with EXIT-to-resection did well with discharge at a median of 10 days post-operatively. All 7 fetuses treated without an EXIT developed respiratory distress following birth requiring an urgent operation; 2 died. CONCLUSION The EXIT-to-resection procedure is a favorable delivery approach for those fetuses with large LM and PMC near birth.

Abstract
Congenital thoracic malformations (CTMs) are a heterogeneous group of rare disorders that may involve the airways or lung parenchyma. The authors have focused on the condition that causes the most controversy, namely, congenital cystic adenomatoid malformation (CCAM). The reported incidence is 3.5 and 0.94 per 10,000 live births for CTMs and CCAMs respectively. Ultrasound is the antenatal imaging modality of choice for screening for CCAMs whilst magnetic resonance imaging is complimentary for morphological and volumetric evaluation of the foetal lung. Most CCAMs are detected antenatally with only a small proportion presenting postnatally. Only a few CCAMs cause foetal problems, with foetal hydrops being the best predictor of death. Although many CCAMs regress during pregnancy, most remain detectable postnatally by CT scans. Surgical excision of symptomatic lesions is relatively straightforward, but management of asymptomatic lesions is controversial. Some surgeons adopt a "wait and see" approach operating only on those patients who develop symptoms, but others operate on asymptomatic patients usually within the first year of life. Due to the potential of malignant transformation, children should have long term follow up. There is an urgent need to delineate the natural history of antenatally detected CCAMs to guide future management.

Abstract
OBJECTIVE To report the performance of fetal bronchoscopy in a case of pulmonary sequestration. MATERIALS AND METHODS A 24 year-old female, Gravida 2, Para 1, was referred at 27.5 weeks with a large fetal left lung mass with marked right mediastinal shift and no visible normal left lung. Differential diagnosis included possible bronchial atresia. RESULTS The patient underwent fetal laryngoscopy and fetal bronchoscopy at 31.5 weeks. The right lung and a portion of the left lung expanded during surgery as a result of bronchial lavage. Bronchial atresia or bronchogenic cyst were not found. Pregnancy continued uneventfully, with continuous growth of the right lung and a small amount of left lung. The patient delivered vaginally at term. The baby underwent thoracoscopic resection of a pulmonary sequestration at 10.5 months of age and did well. CONCLUSION Fetal bronchoscopy is feasible. The procedure may prove useful in the differential diagnosis and in the potential treatment of different fetal lung lesions, as well as aid in the understanding of the role of bronchial obstruction as a common pathophysiologic mechanism for different fetal lung masses. Risks and benefits of fetal bronchoscopy warrant further experience.

Abstract
Confusion, controversy, and uncertainty are all terms applicable to the diagnosis and management of congenital lung lesions both prenatally and postnatally. This review examines the current status of fetal diagnosis and treatment of these lesions; reviews the various classifications, including congenital cystic adenomatoid malformation/congenital pulmonary airway malformation, sequestrations, variants and hybrid lesions; discusses the risk of malignant transformation or misdiagnosis with pleuropulmonary blastoma; presents the arguments in favor and against resection of asymptomatic lesions, the timing of such resection, and the long-term pulmonary function after resection; and reviews the experience with thoracoscopic resection of congenital lung lesions.

Abstract
PURPOSE The aim of this study was to identify the most accurate prenatal predictors of outcomes and need for fetal surgery for fetuses with high-risk lung masses and vascular tumors. METHODS The records of all fetuses with high-risk lung mass (congenital cystic adenomatoid malformation-volume ratio > 1.6 or findings of hydrops) and vascular tumor evaluated between July 2001 and March 2011 were reviewed retrospectively. Hydrops was defined as accumulation of fluid in 2 or more compartments. RESULTS Of fetuses with high-risk lung mass, hydrops was identified in 46% (11/24). Fetuses with hydrops and an abnormal echocardiogram (n = 8) demonstrated poor survival without fetal surgery (13%) compared with 100% survival in fetuses with hydrops and a normal echocardiogram (n = 3; P = .02). Of 21 fetuses with vascular tumor (11 sacrococcygeal and 8 cervical teratomas; 2 hemangioendotheliomas), hydrops was identified in 29% and an abnormal echocardiogram in 57%. All fetuses with hydrops had an abnormal echocardiogram and either died (n = 5) or required fetal surgery (n = 1). However, all fetuses with abnormal echocardiograms alone (n = 7) survived without fetal intervention. CONCLUSIONS For fetuses with lung mass, an abnormal echocardiogram in the setting of hydrops is the best predictor of mortality and need for fetal surgery. For fetuses with vascular tumor, hydrops in the setting of high-output physiology best predicts demise and need for fetal surgery.

Abstract
Congenital lung lesions, mostly congenital cystic adenomatoid malformations (CCAMs) and bronchopulmonary sequestrations (BPSs), are uncommon disorders. Prenatal intervention in severely affected (hydropic) fetuses has drastically improved perinatal survival. Not much is known, however, on the short-term and long-term respiratory and neurodevelopmental outcome. Several small case series have been reported and suggest an increased incidence of neonatal morbidity, mainly associated with prematurity and respiratory failure at birth. Overall, neonatal mortality and morbidity after prenatal interventions for CCAM seems to be worse than for BPS. This review focuses on the neonatal outcome after prenatal intervention for congenital lung lesions and summarizes the results reported in the literature.

Abstract
Most fetal lung masses present by mid gestation, grow during the canalicular phase of lung development (18-26 weeks of gestation), and plateau in growth or shrink after 26 weeks of gestation. We describe the unique case of a fetal lung mass presenting at 37 weeks of gestation with hydrops and fetal heart failure. The late growth of this lesion and resultant hydrops prompted resection as part of the ex utero intrapartum treatment. Histopathology revealed a rare, recently described fetal lung interstitial tumor. This case demonstrates that a subset of fetal lung masses may continue to grow later in gestation and emphasizes the need for late gestation imaging and close follow-up in this patient cohort.

Abstract
The field of neonatal surgery is now inextricably linked to the field of obstetrics. Neonatologists and surgical specialists experienced with the postnatal management and outcomes of infants with various disorders now look in utero along with obstetricians and fetal medicine specialists to characterize the development and well-being of fetuses with congenital anomalies with a goal to optimize fetal, perinatal and postnatal management. The purpose of this article is to examine how prenatal diagnosis and therapy has influenced neonatal surgery. An overview of prenatal diagnosis and the evolution of fetal therapy are provided. In addition, we review the impact of prenatal diagnosis and therapy on the management and outcomes of infants with specific anomalies, including congenital lung malformations, sacrococcygeal teratoma, myelomeningocele, giant fetal neck masses, diaphragmatic hernia and congenital heart defects.

Abstract
The widespread availability of high resolution ultrasound equipment and almost universal routine anatomy scanning in all pregnant women in the developed world has lead to increased detection of abnormalities in the fetal thorax. Already in the 1980s, large pleural effusions and significant macrocystic lesions in the fetus were easily detected on ultrasound. However, smaller lung tumours were often missed. Nowadays, fetal medicine centres receive many referrals for evaluation of fetal lung lesions, of which the most common are congenital cystic adenomatoid malformation and bronchopulmonary sequestration. Almost invariably, both the parents and the referring physicians experience anxiety after detection of large lung masses in the fetus. However, the vast majority of the currently detected fetal lung lesions have an excellent prognosis without the need for prenatal intervention. In the small group of fetuses in which the prognosis is poor, almost exclusively those with concomitant fetal hydrops and cardiac failure, several options for fetal therapy exist, often with a more than 50% survival rate. Indications, techniques, complications and outcomes of these interventions will be described in this review.

Abstract
Congenital CNS abnormalities have been targets for prenatal intervention since the founding of fetal surgery 30 years ago, but with historically variable results. Open fetal neurosurgery for myelomenigocele has demonstrated the most promising results of any CNS malformation. Improvements in the understanding of congenital diseases and in fetal surgical techniques have reopened the door to applying fetal surgery to other congenital CNS abnormalities. Advances in gene therapy, bioengineering and neonatal neuroprotection will aid in the future expansion of fetal neurosurgery to other CNS disorders.

Abstract
AIM The purpose of this study is to evaluate the accuracy of prenatal diagnostic features, particularly congenital cystic adenomatoid malformation volume ratio (CVR), in predicting outcomes for fetuses with lung masses. METHODS The records and imaging features of all fetuses referred to the Texas Children's Fetal Center with a fetal lung mass between July 2001 and May 2010 were reviewed retrospectively. Data collected included gestational age (GA) at diagnosis, fetal magnetic resonance imaging findings, CVR, mass size, nature of fetal treatment, surgical findings, pathology, and outcome. Data were analyzed for predicting development of hydrops or the need for fetal therapy using receiver operating characteristic curves. RESULTS Of 82 fetuses (41 male) evaluated for a lung mass, 53 (65%) were left-sided (1 bilateral), and the mean (SD) GA at diagnosis was 21.5 (4.3) weeks. Seventy-three fetuses underwent fetal magnetic resonance imaging at a mean (SD) GA of 26.1 (4.6) weeks. Thirteen fetuses (16%) had fetal treatment. Four fetuses with hydrops underwent open fetal surgical resection, and 3 survived. Six fetuses with large lung masses and persistent mediastinal compression near term underwent ex-utero intrapartum therapy-to-resection procedures, and 3 fetuses with hydrops underwent serial thoracentesis. Congenital cystic adenomatoid malformation volume ratio correlated strongly with the development of hydrops and the need for fetal therapy with an area under the receiver operating characteristic curve of 0.96 (P < .0001) and 0.88 (P < .0001), respectively. Of 18 fetuses with a CVR greater than 2.0 compared with 2 (3%) of 60 with a CVR of 2.0 or less, 10 (56%) required fetal intervention (P < .0001). CONCLUSION Congenital cystic adenomatoid malformation volume ratio correlates strongly with the development of fetal hydrops and the need for fetal intervention. A threshold value of 2.0 yields the most powerful statistical results.

Abstract
An increasing number of fetal anomalies are being diagnosed prior to birth, some of them amenable to fetal surgical intervention. We discuss the current clinical status and recent advances in endoscopic and open surgical interventions. In Europe, fetoscopic interventions are widely embraced, whereas the uptake of open fetal surgery is much less. The indications for each access modality are different, hence they cannot substitute each other. Although the stage of technical experimentation is over, most interventions remain investigational. Today there is level I evidence that fetoscopic laser surgery for twin-to-twin transfusion syndrome is the preferred therapy, but this operation actually takes place on the placenta. In terms of surgery on the fetus, an increasingly frequent indication is severe congenital diaphragmatic hernia as well as myelomeningocele. Overall maternal safety is high, but rupture of the membranes and preterm delivery remain a problem. The increasing application of fetal surgery and its mediagenicity has triggered the interest to embark on fetal surgical therapy, although the complexity as well as the overall rare indications are a limitation to sufficient experience on an individual basis. We plead for increased exchange between high volume units and collaborative studies; there may also be a case for self-regulation. Inclusion of patients into trials whenever possible should be encouraged rather than building up casuistic experience.

Abstract
OBJECTIVE The purpose of this study is to evaluate the effect of prenatal steroid treatment in fetuses with sonographically diagnosed congenital cystic adenomatoid malformations (CCAMs). METHODS This was an institutional review board-approved retrospective review of 372 patients referred to the University of California, San Francisco (UCSF), for fetal CCAM. Inclusion criteria were (1) a predominately microcystic CCAM lesion sonographically diagnosed at our institution, (2) maternal administration of a single course of prenatal corticosteroids (betamethasone), and (3) no fetal surgery. CCAM volume-to-head ratio (CVR), presence of hydrops, mediastinal shift, and diaphragm eversion were assessed before and after administration of betamethasone. The primary end points were survival to birth and neonatal discharge. RESULTS Sixteen patients with predominantly microcystic CCAMs were treated with prenatal steroids. Three were excluded because of lack of follow-up information. All remaining fetuses (13/13) survived to delivery and 11/13 (84.6%) survived to neonatal discharge. At the time of steroid administration, all patients had CVR greater than 1.6, and 9 (69.2%) also had nonimmune hydrops fetalis. After a course of steroids, CVR decreased in 8 (61.5%) of the 13 patients, and hydrops resolved in 7 (77.8%) of the 9 patients with hydrops. The 2 patients whose hydrops did not resolve with steroid treatment did not survive to discharge. CONCLUSION In high-risk fetal patients with predominantly microcystic CCAM lesions, betamethasone is an effective treatment. This series is a pilot study for a prospective randomized trial comparing treatment of CCAM with betamethasone to placebo.

Abstract
The antenatal finding of a congenital thoracic malformation (CTM) leads to anxiety in the parents and uncertainty as to the optimal management. The antenatal spectrum of CTM includes congenital cystic adenomatoid malformation, sequestration, congenital lobar emphysema, enteric and bronchogenic cysts, and bronchial atresia. Most lesions require no antenatal intervention, and shrink substantially in the third trimester, but if fetal hydrops develops, then antenatal intervention is required, occasionally medical but more usually surgical, because mortality is high. If the baby is symptomatic in the newborn period, then some form of surgical intervention is clearly required. The asymptomatic baby presents a therapeutic dilemma. Advocates of early surgery point to the complications of CTM, which include infection, pneumothorax, bleeding and malignant transformation. Those who are proponents of conservative management retort that some CTM disappear postnatally, and that the complication rate is unknown; many children appear never to need surgery. Furthermore, there is clearcut evidence that excision of a CTM does not totally eliminate the risk of a subsequent malignancy. It is clear that, both antenatally and postnatally, counselling of the family on a case by case basis is needed. The limitations of present evidence should be stressed. Different families will make different decisions about postnatal surgery in an asymptomatic baby. If surgery is performed, morbidity is low, particularly with a video-assisted thoracoscopic (VATS) procedure.

Abstract
BACKGROUND Antenatally detected asymptomatic congenital cystic lung lesions may be managed conservatively or by surgical resection. We undertook a systematic review and meta-analysis to quantify the risks of elective surgery, emergency surgery, and observation. METHODS All series published between 1996 and 2008, where the postnatal management of congenital cystic lung lesions was described, were reviewed. A meta-analysis was performed to determine whether elective or emergency surgery was associated with a higher risk of adverse outcomes. RESULTS There were 41 reports describing 1070 patients (of whom 79% were antenatally detected). Five hundred five neonates survived without surgery into infancy, of whom only 16 (3.2%) became symptomatic. For all ages, elective surgery was associated with significantly less complications than emergency surgery. The risk ratio was 2.8 (95% confidence interval, 1.4-5.5; P < .005) when comparing complications after elective surgery with emergency surgery. CONCLUSIONS The risk of asymptomatic cases developing symptoms is small. However, elective surgery is associated with a better outcome than emergency surgery. If elective surgery is undertaken, it should be performed before 10 months. Although no prognostic indicators have so far been identified in the literature, a conservative approach may be appropriate for small lesions.
