RESUMO
BACKGROUND: The management of asymptomatic congenital lung malformations (CLM) is debated, and pulmonary function of patients with CLM is seldom discussed. Short-term respiratory outcome in patients operated for CLM was assessed in order to better define surgical impact. METHODS: A retrospective study on patients operated for CLM between 2012 and 2021 was performed. Respiratory function was assessed with tidal breath analysis (TBA) in spontaneous sleep within 2 years of life. Patients with comorbidities affecting pulmonary function were excluded. Three variables were studied: tPTEF/tE (time to peak tidal expiratory flow/total expiratory time), tV (tidal volume), RR (respiratory rate). Results were assessed as z-score (normal ±1.64) and expressed as median (range). Pre- and post-operative results were compared, as well as post-operative results of disease and surgery type subgroups. RESULTS: Thirty-nine patients were included. Median pre- and post-operative tPTEF/tE were normal (pre: -0.32 (-2.12; +1.56); post: -0.18 (-1.62; +2.43)). Patients with extralobar sequestration had pre-operative high median RR, which improved after sequestrectomy (pre: +1.99 (-2.49; +7.43); post -0.22 (-3.01; +1.18)). All groups had reduced pre-operative median tV, which restored after surgery (pre: -2.15 (-9.75; +0.91); post: -0.35 (-6.65; +3.14)). Patients undergoing lobectomy and patients with intralobar sequestration showed greater improvement. Median post-operative TBA results were normal for all sub-groups except for reduced tV in patients operated with thoracotomy (-2.27 (-6.12; +5.26)). CONCLUSIONS: Patients with clinically asymptomatic CLM can have pathologic pulmonary function tests, which improve after surgery. These results add to the elements in favor of an interventional approach. LEVEL OF EVIDENCE: III, Treatment study.
RESUMO
BACKGROUND: Aim of the present report was to investigate the repercussions of COVID-19 pandemic on the procedural volumes and on the main indications of pediatric digestive endoscopy in Italy. METHODS: An online survey was distributed at the beginning of December 2020 to Italian digestive endoscopy centers. Data were collected comparing two selected time intervals: the first from 1st of February 2019 to 30th June 2019 and the second from 1st February 2020 to 30th June 2020. RESULTS: Responses to the survey came from 24 pediatric endoscopy Units. Globally, a reduction of 37.2% was observed between 2019 and 2020 periods with a significant decrease in median number of procedures (111 vs 57, p < 0.001). Both the median number of procedures performed for new diagnoses and those for follow-up purposes significantly decreased in 2020 (63 vs 36, p < 0.001 and 42 vs 21, p< 0.001, respectively). We reported a drastic reduction of procedures performed for suspected Celiac Disease and Functional Gastrointestinal Disorders (55.1% and 58.0%, respectively). Diagnostic endoscopies for suspected IBD decreased of 15.5%, whereas procedures for Mucosal Healing (MH) assessment reduced of 48.3%. CONCLUSIONS: Our study provides real-world data outlining the meaningful impact of COVID-19 on pediatric endoscopy practice in Italy.

In newborns with congenital diaphragmatic hernia (CDH), the radiographic lung area is correlated with functional residual capacity (FRC) and represents an alternative method to estimate lung hypoplasia. In a cohort of newborn CDH survivors, we retrospectively evaluated the relationship between radiographic lung area measured on the 1st day of life and long-term respiratory function. As a secondary analysis, we compared radiographic lung areas and respiratory function between patients undergoing fetal endoscopic tracheal occlusion (FETO) and patients managed expectantly (non-FETO). Total, ipsilateral, and contralateral radiographic areas were obtained by tracing lung perimeter as delineated by the diaphragm and rib cage, excluding mediastinal structures and herniated organs. Tidal volume (VT), respiratory rate (RR), and their Z-Scores when compared to the norm were collected from pulmonary function tests (PFTs) performed at 12 ± 6 months of age. Linear regression analyses using the absolute Z-Score values for each parameter were performed. In CDH survivors, an increase in total and ipsilateral lung area measured at birth was related to a reduction in the absolute Z-Score for VT in PFTs (p = 0.046 and p = 0.023, respectively), indicating a trend toward an improvement in pulmonary volumes and VT normalization. Radiographic lung areas were not significantly different between FETO and non-FETO patients, suggesting a volumetric lung increase due to prenatal intervention. However, the mean Z-Score value for RR was significantly higher in the FETO group (p < 0.001), probably due to impaired diaphragmatic motility in the most severe cases. Further analyses are necessary to better characterize the role of the radiographic pulmonary area in the prognostic evaluation of respiratory function in patients with CDH. Clinical Trial Registration: This trial was registered at ClinicalTrials.gov with the identifier NCT04396028.
RESUMO
INTRODUCTION: Consensus on the best postnatal radiological evaluation of congenital lung malformations (CLMs) is still lacking. In recent years, the interest on magnetic resonance imaging (MRI) has grown, but its role is still unknown. AIM: The aim of the study was to identify the best preoperative diagnostic assessment for CLM. MATERIALS AND METHODS: All patients with a prenatal suspicion of CLM between January 2014 and February 2018 were studied. Asymptomatic newborns underwent MRI, during spontaneous sleep without contrast. Patients with a positive MRI were scheduled for computed tomography (CT) within the fourth month of life. Thoracoscopic resection was performed in cases with a pathological CT. MRI, CT, and surgical findings were compared based on dimension, localization, and features of the CLM using the Cohen's kappa test (K). RESULTS: A total of 20 patients were included (10 males). No difference was found in the diameter and site of the lesions always localized in the same side (K = 1) and in the same pulmonary lobe (K = 1). Infants who underwent thoracoscopic resection included: three congenital pulmonary airway malformations (CPAMs), five extralobar and eight intralobar sequestrations (bronchopulmonary sequestrations [BPSs]), three bronchogenic cysts, and one congenital emphysema. The concordance between MRI and CT and between radiological investigations and pathology was satisfactory for the greatest part of the studied variables. MRI showed sensitivity of 100%, specificity of 82%, positive predictive value of 50% and negative predictive value of 100% for CPAM and 77, 100, 100, and 80% for BPS, respectively. CONCLUSION: MRI proved to be a reliable diagnostic investigation for CLM with high sensitivity and specificity. Early MRI in spontaneous sleep without contrast and preoperative contrast CT scan is a valuable preoperatory assessment.

INTRODUCTION: We aim to assess gastroesophageal reflux (GER) in patients treated for congenital diaphragmatic hernia (CDH) and to determine whether a pH-metry investigation should be routinely performed in follow-up. MATERIALS AND METHODS: Twenty-four-hour pH-metry at 1 year was performed in all patients treated for CDH between January 2014 and April 2015 (Group 1). We compared pH-metry results to those of two other groups: children treated for esophageal atresia (EA) (Group 2) and normal babies presenting with typical symptoms (Group 3). All the pH-metric findings were analyzed and compared. Intra-group analysis was performed in Group 1. RESULTS: Group 1 consisted of 21, Group 2 of 24, and Group 3 of 21 patients. Mean pH-metry values for Groups 1, 2, and 3 were, respectively: reflux index (RI) 4.3, 5.1, and 3.9; total number of refluxes (NR) 79.5, 88.8, and 88.7; refluxes longer than 5' (R > 5) 1.7, 2.3, and 1.47; and longest reflux episode (LR) 11.4, 13.3, and 8.6. No significant differences were found between Group 1 and the others. Only two CDH patients presented with GER-related symptoms. Patch was associated with significantly higher RI (8.5 vs. 2.98, p = 0.03). The worse was the defect, the worse were the pH-metric results (RI: A3.09, B3.15, and C9.1). CONCLUSION: We believe that a routine GER assessment should be performed in all CDH patients regardless the presence of symptoms. LEVEL OF EVIDENCE: This is a Level II study.
