There is wide practice variation in the use of laparoscopic fundoplication (LF) versus gastrojejunostomy (GJ) tube insertion for children who do not tolerate gastric feeds. Using weight gain as an objective proxy of adequate nutrition, we sought to evaluate the difference in weight gain between LF and GJ.A retrospective, cohort study was conducted of patients ≤ 2 years who underwent LF or GJ between 2014 and 2019 at a single institution. Patient characteristics, change in weight 1-year post-procedure and frequency of unplanned healthcare utilization encounters were collected and examined.A total of 125 patients (50.4%LF, 49.6%GJ) were identified. Adjusted modeling demonstrated that on average, there was an additional 0.85-unit increase in weight-for-age Z scores in the LF compared to the GJ cohort (p = 0.01). The GJ cohort had significantly more unplanned healthcare utilization encounters (4.2, SD 3.4) compared to LF (3.0, SD 3.1) (p = 0.03). Furthermore, the GJ cohort underwent an average of 3.3 planned GJ exchanges within 1-year post-procedure.In the first year post-operatively, LF is associated with increased weight gain and fewer unplanned and overall healthcare encounters compared to GJ. Long-term outcomes including weight gain and quality-of-life measures should be studied to develop standardized guidelines for this common clinical scenario.

Vascular malformations are commonly encountered in the pediatric population. This article reviews the imaging appearances of simple and syndromic vascular malformations in infants and children that radiologists should know and provides imaging guidelines based on an evidence-based approach. Malformations are discussed within the framework of the International Society for the Study of Vascular Anomalies classification system.

The ability of computed tomography (CT) to distinguish between benign congenital lung malformations and malignant cystic pleuropulmonary blastomas (PPBs) is unclear.To assess whether chest CT can detect malignant tumors among postnatally detected lung lesions in children.This retrospective multicenter case-control study used a consortium database of 521 pathologically confirmed primary lung lesions from January 1, 2009, through December 31, 2015, to assess diagnostic accuracy. Preoperative CT scans of children with cystic PPB (cases) were selected and age-matched with CT scans from patients with postnatally detected congenital lung malformations (controls). Statistical analysis was performed from January 18 to September 6, 2020. Preoperative CT scans were interpreted independently by 9 experienced pediatric radiologists in a blinded fashion and analyzed from January 24, 2019, to September 6, 2020.Accuracy, sensitivity, and specificity of CT in correctly identifying children with malignant tumors.Among 477 CT scans identified (282 boys [59%]; median age at CT, 3.6 months [IQR, 1.2-7.2 months]; median age at resection, 6.9 months [IQR, 4.2-12.8 months]), 40 cases were extensively reviewed; 9 cases (23%) had pathologically confirmed cystic PPB. The median age at CT was 7.3 months (IQR, 2.9-22.4 months), and median age at resection was 8.7 months (IQR, 5.0-24.4 months). The sensitivity of CT for detecting PPB was 58%, and the specificity was 83%. High suspicion for malignancy correlated with PPB pathology (odds ratio, 13.5; 95% CI, 2.7-67.3; P = .002). There was poor interrater reliability (κ = 0.36 [range, 0.06-0.64]; P .001) and no significant difference in specific imaging characteristics between PPB and benign cystic lesions. The overall accuracy rate for distinguishing benign vs malignant lesions was 81%.This study suggests that chest CT, the current criterion standard imaging modality to assess the lung parenchyma, may not accurately and reliably distinguish PPB from benign congenital lung malformations in children. In any cystic lung lesion without a prenatal diagnosis, operative management to confirm pathologic diagnosis is warranted.

Midline catheters have emerged as a successful alternative to peripheral venous catheters (PVCs) and central venous catheters (CVCs) in select patients. Midline catheters allow for greater duration of access when compared with PVCs and avoid the critical complications associated with CVCs. This article describes the implementation of the Powerwand® midline at a large paediatric tertiary care facility in acute and intensive care settings, and presents illustrative cases of the catheter in use. Product evaluation was performed by a paediatric vascular access team of registered nurses and included information on patient outcomes, inserter satisfaction, patient satisfaction, and cost effectiveness.

Vascular anomalies encompass a collection of diagnoses that differ greatly in terms of clinical presentation, natural history, imaging findings, and management. The purpose of this article is to review diagnostic imaging findings of vascular malformations and vascular tumors, excluding the central nervous system, that occur beyond childhood. A widely accepted classification system created by the International Society for the Study of Vascular Anomalies provides a framework for this review, focusing on the entities most likely to be encountered by general radiologists, although several rare but clinically important entities are also reviewed.
