J Surg Res 2024; 302:755-764. [PMID: 39216458 DOI: 10.1016/j.jss.2024.07.118] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 07/25/2024] [Accepted: 07/31/2024] [Indexed: 09/04/2024]
Abstract
INTRODUCTION Congenital lung malformations (CLMs) are diverse and readily diagnosed on prenatal ultrasound. Postnatal computed tomography (CT) characteristics, including volume, are used in centers for the clinical decision-making of asymptomatic CLM. We aim to evaluate the relationship of prenatal CLM volume ratio (CVR) to postnatal CT characteristics by suspected prenatal diagnosis and postnatal radiological diagnosis. METHODS We performed a single-center retrospective review of all patients evaluated with prenatally diagnosed CLM (May 2015-December 2022). Demographics, prenatal imaging findings at initial evaluation, and postnatal radiological diagnosis/imaging findings were analyzed with descriptive statistics. Pairwise correlation coefficient tests were performed to analyze the correlation between prenatal CVR and postnatal CT lesion size stratified by diagnosis. RESULTS Of 123 patients referred and evaluated, suspected prenatal diagnoses consisted of 68 bronchial atresia (BA), 20 intralobar bronchopulmonary sequestration (iBPS), 20 extralobar bronchopulmonary sequestration (eBPS), and nine congenital pulmonary airway malformation (CPAM). Postnatal radiological diagnoses consisted of 53 BA, 22 iBPS, 14 eBPS, and 20 CPAM. Overall correlation coefficient of prenatal CVR to postnatal CT lesion size volume was 0.56. By suspected prenatal diagnosis, correlation coefficients were 0.61 (BA), 0.59 (iBPS), 0.29 (eBPS), and 0.51 (CPAM). For postnatal radiological diagnosis, correlation coefficients were 0.58 (BA), 0.56 (iBPS), 0.33 (eBPS), and 0.62 (CPAM). CONCLUSIONS Our results indicate that initial CVR is overall consistent with the postnatal CT lesion size. This correlation is present in suspected prenatal diagnoses of BA and iBPS and postnatal radiological diagnoses of BA, iBPS, and CPAM. Additional studies analyzing long-term follow-up should be conducted to specify the safety of patients who undergo observation rather than surgical intervention.

The Management of Asymptomatic Congenital Pulmonary Airway Malformation: Results of a European Delphi Survey. CHILDREN 2022; 9:children9081153. [PMID: 36010044 PMCID: PMC9406306 DOI: 10.3390/children9081153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Revised: 07/14/2022] [Accepted: 07/20/2022] [Indexed: 11/17/2022]
Abstract
Consensus on the optimal management of asymptomatic congenital pulmonary airway malformation (CPAM) is lacking, and comparison between studies remains difficult due to a large variety in outcome measures. We aimed to define a core outcome set (COS) for pediatric patients with an asymptomatic CPAM. An online, three-round Delphi survey was conducted in two stakeholder groups of specialized caregivers (surgeons and non-surgeons) in various European centers. Proposed outcome parameters were scored according to level of importance, and the final COS was established through consensus. A total of 55 participants (33 surgeons, 22 non-surgeons) from 28 centers in 13 European countries completed the three rounds and rated 43 outcome parameters. The final COS comprises seven outcome parameters: respiratory insufficiency, surgical complications, mass effect/mediastinal shift (at three time-points) and multifocal disease (at two time-points). The seven outcome parameters included in the final COS reflect the diversity in priorities among this large group of European participants. However, we recommend the incorporation of these outcome parameters in the design of future studies, as they describe measurable and validated outcomes as well as the accepted age at measurement.

Abstract
BACKGROUND Whether to operate on asymptomatic patients with congenital lung malformations (CLMs) remains controversial. Our study intended to find out the proportion of hidden infection in CLMs and its effect on surgery, to provide help for the management of asymptomatic CLMs patients. METHODS A retrospective review of the medical records of patients with asymptomatic CLMs from January 2011 to December 2020 was performed in our center. Selected asymptomatic patients were divided into a non-hidden infection group (NHI) and a hidden infection group (HI). RESULTS A total of 581 asymptomatic CLMs patients were included in this study. Thirty-two percent of asymptomatic CLMs patients had hidden infection in the lesion. Among various CLMs diseases, intralobular pulmonary sequestration had the highest percentage of hidden infection (48.8%). With age, the proportion of HI gradually increased. Patients in the HI and NHI groups were 223 and 121. The incidence of pleural adhesion and focal abscess in the HI group were 14.9 and 7.4%. Statistical significances were shown between the two groups in intraoperative blood loss (p = 0.002), operation time (p = 0.045), chest tube drainage time (p < 0.001), postoperative hospital stay (p < 0.001), and air leak (p = 0.012). CONCLUSION The proportion of HI detected by postoperative pathological results was high and they could increase the difficulty and risk of surgery. Therefore, early surgery may be a more appropriate choice for the management of asymptomatic CLMs patients.

Abstract
PURPOSE For the approximately three quarters of patients with a prenatal diagnosis of congenital pulmonary airway malformation (CPAM) who are asymptomatic at birth, the chance of eventually developing symptoms is unknown. We sought to explore the natural history of asymptomatic CPAM. METHODS We searched EMBASE, MEDLINE, and the first 50 results from Google Scholar. Studies describing the natural history of prenatally diagnosed, initially asymptomatic CPAM were included. For asymptomatic patients initially managed non-surgically, we tabulated the proportion who went on to develop symptoms as well as the median age at symptom development. RESULTS We included data from 19 retrospective studies on 353 patients. Of the 128 patients managed expectantly, 31 (24.2%) developed symptoms requiring surgical intervention. The median age at symptom development was 7.5 months (range 15 days-5 years). CONCLUSION The risk for developing respiratory symptoms exists with originally asymptomatic CPAM patients, but the exact risk is difficult to predict. Parents may be given the value of approximately 1 in 4 as an estimate of the proportion of asymptomatic CPAM patients who go on to develop symptoms, which will help them make an informed decision regarding the option of elective surgery.

Abstract
The present study aimed to examine the value of ultrasonic soft markers in prenatal screening by analyzing the clinical outcome of fetuses with ultrasonic soft markers during the second trimester of pregnancy. A retrospective analysis was performed to evaluate the outcome of 591 fetuses with ultrasonic soft markers from January 2015 to August 2016 in Zhongnan Hospital of Wuhan University, China. It was found that 591 fetuses showed ultrasonic soft markers in 4927 cases with the occurrence rate being 12.0%. Among them, 564 fetuses (95.4%) were delivered and the remaining 27 cases (4.6%) were aborted. Five hundred and sixty-seven cases had single ultrasonic soft marker, including echogenic intracardiac focus (n=343), mild renal pelvis dilatation (n=116), short long bones (n=72), single umbilical artery (n=31), mild lateral ventriculomegaly (n=21), choroid plexus cysts (n=19), and echogenic bowel (n=13), with the disappearing rates in pregnancy being 97.1% (333/343), 77.6% (90/116), 0% (0/72), 0% (0/31), 57.1% (12/21), 89.5% (17/19) and 61.5% (8/13) respectively. The rate of pregnancy termination due to single ultrasonic soft marker was 3.4% (19/567), and that was 33.3% (8/24) due to two ultrasonic soft markers with the difference being statistically significant (P<0.05). The reasons of pregnancy termination included malformations (polycystic kidney, cleft lip and palate, congenital heart diseases, pcromphalus, hypospadias, hydrocephalus), chromosome abnormality, and stillbirth. It was concluded that single ultrasonic soft marker is usually transient manifestation in pregnancy. Without the other structural defects, single ultrasonic soft marker usually disappears spontaneously with favorable prognosis in a low-risk population. It is suggested that ultrasonic soft markers should be appropriately interpreted to avoid unnecessary invasive examination.

Abstract
PURPOSE Variation in management characterizes treatment of infants with a congenital pulmonary airway malformation (CPAM). This review addresses six clinically applicable questions using available evidence to provide recommendations for the treatment of these patients. METHODS Questions regarding the management of a pediatric patient with a CPAM were generated. English language articles published between 1960 and 2014 were compiled after searching Medline and OvidSP. The articles were divided by subject area and by the question asked, then reviewed and included if they specifically addressed the proposed question. RESULTS 1040 articles were identified on initial search. After screening abstracts per eligibility criteria, 130 articles were used to answer the proposed questions. Based on the available literature, resection of an asymptomatic CPAM is controversial, and when performed is usually completed within the first six months of life. Lobectomy remains the standard resection method for CPAM, and can be performed thoracoscopically or via thoracotomy. There is no consensus regarding a monitoring protocol for observing asymptomatic lesions, although at least one chest computerized tomogram (CT) should be performed postnatally for lesion characterization. An antenatally identified CPAM can be evaluated with MRI if fetal intervention is being considered, but is not required for the fetus with a lesion not at risk for hydrops. Prenatal consultation should be offered for infants with CPAM and encouraged for those infants in whom characteristics indicate risk of hydrops. CONCLUSIONS Very few articles provided definitive recommendations for care of the patient with a CPAM and none reported Level I or II evidence. Based on available information, CPAMs are usually resected early in life if at all. A prenatally diagnosed congenital lung lesion should be evaluated postnatally with CT, and prenatal counseling should be undertaken in patients at risk for hydrops.

Abstract
Antenatal diagnosis of lung lesion has become more accurate resulting in dilemma and controversies of its antenatal and postnatal management. Majority of antenatally diagnosed congenital lung lesions are asymptomatic in the neonatal age group. Large lung lesions cause respiratory compromise and inevitably require urgent investigations and surgery. The congenital lung lesion presenting with hydrops requires careful postnatal management of lung hypoplasia and persistent pulmonary hypertension. Preoperative stabilization with gentle ventilation with permissive hypercapnia and delayed surgery similar to congenital diaphragmatic hernia management has been shown to result in good outcome. The diagnostic investigations and surgical management of the asymptomatic lung lesions remain controversial. Postnatal management and outcome of congenital cystic lung lesions are discussed.

Abstract
AIM To review the outcome of all antenatally diagnosed conservatively managed congenital lung malformations (CLMs) managed at our centre. METHODS All patients diagnosed antenatally with cystic lung malformations from 2001 to 2011, at a tertiary referral paediatric surgical centre practising a policy of conservative management of asymptomatic cases, were retrospectively reviewed. Data were collected from medical case notes and radiology reports. Ethical approval was obtained from our institutional research and development department. RESULTS The complete records of 74 fetuses antenatally diagnosed with CLM were reviewed. There were 72 live births, at a median gestation of 39.6 weeks. Emergency lobectomy was performed in one symptomatic neonate. Elective lobectomies were performed at parental request in three asymptomatic infants, one of whom had a family history of synovial sarcoma. Two patients developed pneumonia in the affected lobe during early childhood and proceeded to lobectomy at the age of 3 years. One patient with a bronchopulmonary sequestration required embolisation for cyanotic episodes. The remaining 65 patients have been conservatively managed to date, and none have required hospital admission. Less than a quarter report mild respiratory symptoms such as cough or wheeze. Median follow-up is 5 years. CONCLUSIONS This retrospective cohort study of 74 consecutive CLMs diagnosed antenatally over a 10-year period demonstrates that most of these lesions will remain asymptomatic throughout childhood. Although the natural history of CLMs in later years remains to be elucidated, we hope that this report on medium-term outcomes will be useful to clinicians who undertake antenatal counselling and may inform the discussion on how best to manage these children.

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 determine whether the congenital cystic adenomatoid malformation (CCAM) volume ratio (CVR) is associated with fetal and postnatal outcome after prenatal diagnosis and antenatal expectant management in a provincial tertiary referral center that does not offer fetal surgery. METHODS Retrospective cohort of 71 consecutive cases of prenatally diagnosed CCAM meeting study criteria (1996-2004). CVR was calculated on the initial ultrasound at the referral center, and associated with hydrops (Fisher's exact test) and a composite adverse postnatal outcome consisting of death, intubation for respiratory distress, extracorporeal membrane oxygenation, non-elective surgery for symptomatology, or respiratory infection requiring hospital admission (Mann-Whitney test). RESULTS A CVR > 1.6 was significantly associated with hydrops (p = 0.003). In addition, the CVR was significantly associated with the composite adverse postnatal outcome (p = 0.004) at a mean age of follow-up of 41 months (range < 1-117 months). For CVR and postnatal outcome, the area-under-the-curve receiver operating characteristic was 0.81 (95% CI 0.69-0.93, p = 0.006), and choosing a CVR cut-off of < 0.56, the negative predictive value was 100% (95% CI 0.85-1.00). CONCLUSION In a provincial referral center with antenatal expectant management of CCAM, the CVR was associated with hydrops and postnatal outcome, with a CVR < 0.56 predictive of good prognosis after birth.

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.

Abstract
OBJECTIVE To describe the antenatal findings and outcome of fetuses with echogenic lung lesions. METHODS This was a retrospective study of the prenatal sonographic features, antenatal management and outcome of 193 fetuses with an echogenic lung lesion diagnosed at 18-35 weeks of gestation. There were nine cases of congenital high airway obstruction syndrome (CHAOS), 170 cases of cystic adenomatoid malformation (CAM) and 14 cases of pulmonary sequestration (PS). A literature search was also carried out to compare our data with those of previous series. RESULTS The prognosis in our series of fetuses with CHAOS was invariably poor, but the literature describes a handful of survivors after delivery by Cesarean section and ex-utero intrapartum therapy (EXIT). Of the cases in our series with PS and no pleural effusions, more than 95% survived; in half of these cases the lesion resolved antenatally and in the other half sequestrectomy was carried out postnatally. In cases with PS and pleural effusions, successful treatment was provided by the placement of thoracoamniotic shunts or occlusion of the feeding blood vessel by ultrasound-guided laser coagulation or injection of sclerosants. In cases with CAM and no hydrops, there was more than 95% survival and in up to half of the cases there was sonographic evidence of spontaneous antenatal resolution of the hyperechogenic lesion, which was confirmed by postnatal imaging in about 60% of the cases. Of the cases with CAM with hydrops managed expectantly, more than 95% died before or after birth. Of the cases with macrocystic CAM with hydrops, two-thirds survived after placement of a thoracoamniotic shunt. In cases with microcystic CAM with hydrops, there is some evidence that open fetal surgery with lobectomy could improve survival but such treatment is highly invasive for the mother. CONCLUSIONS CHAOS is a severe abnormality, whereas CAM and PS are associated with a good prognosis. In a high proportion of fetuses with hyperechogenic lung lesion, there is spontaneous antenatal resolution and the underlying pathology may be transient bronchial obstruction.

Abstract
Congenital cystic lung disease comprises a broad spectrum of rare but clinically significant developmental abnormalities, including congenital pulmonary adenomatoid malformations, bronchopulmonary sequestrations, bronchogenic cysts, and congenital lobar emphysema that result from perturbations in lung and airway embryogenesis. As congenital lung lesions are now more commonly recognized antenatally, mothers require accurate prenatal counseling and appropriate perinatal management. In light of long-term complications of infection and malignancy, there is growing consensus that infants with asymptomatic lesions should undergo elective excision of congenital pulmonary adenomatoid malformation (CPAM) or bronchopulmonary sequestration (BPS). This review will focus on advancements and current practice in the diagnosis and management of CPAM and BPS, identifying aspects of the literature that are confusing or controversial. Although our knowledge and pre- and postnatal management of lung lesions will continue to evolve and improve, there is a compelling need for a unified clinical and pathological classification system that creates a common platform for discussion, clinical management, and research.

Abstract
We report on the prenatal diagnosis of partial trisomy 1q and monosomy X in a fetus with a congenital lung lesion and hydrops. The finding of hydrops in a fetus with a small lung lesion, congenital cystic adenomatoid malformation (CCAM) volume to head circumference ratio (CVR) 0.78, prompted cytogenetic analysis of amniotic fluid, revealing an unbalanced translocation between chromosomes X and 1 [46,X,der(X)t(X;1)(p11.2;q25 or q31)]. The incidence of chromosomal abnormalities with CCAM lesions is estimated at 1.6%. This is the first reported case of prenatally diagnosed partial trisomy 1q and monosomy X presenting as a fetal lung lesion and hydrops.

Abstract
With the advent of improved antenatal imaging over the past 10 years, the diagnosis, assessment and management of congenital cystic lung abnormalities have changed. These were once considered the exclusive domain of the surgeon, who had the authority to operate on all congenital cystic lung abnormalities regardless of size or clinical signs in order to avoid the risk of cancer and improve lung growth in even asymptomatic infants. Clinicians are reconsidering this approach in the light of an appreciation of the spontaneous improvement and possible resolution that occurs over months to years with many of these lesions. The risks of subsequent cancer are poorly understood and probably overstated, whereas the magnitude of compensatory lung growth is poorly defined in the majority of children with small unilateral congenital cystic abnormalities. The evolution of regional, national and ideally international databases will provide much-needed longitudinal data to better inform clinicians of the optimal way in which to manage these children.
