Objective: Evaluate if hyperosmolar water-soluble contrast challenges (CC) can improve clinical outcomes and reduce hospital length-of-stay (LOS) in children with adhesive small bowel obstruction (ASBO).

Background: Despite documented efficacy of CC algorithms in adults with ASBO, ongoing variability exists in management of children.

Methods: This is a multi-institutional prospective, pre/post-algorithm implementation study of a contrast challenge algorithm in children (≤18 y) admitted with ASBO (10/2021-09/2023).

Background/purpose: Controversy persists regarding the ideal surgical approach for repair of esophageal atresia with tracheoesophageal fistula (EA/TEF). We examined complications and outcomes of infants undergoing thoracoscopy and thoracotomy for repair of Type C EA/TEF using propensity score-based overlap weights to minimize the effects of selection bias.

Methods: Secondary analysis of two databases from multicenter retrospective and prospective studies examining outcomes of infants with proximal EA and distal TEF who underwent repair at 11 institutions was performed based on surgical approach.

The purpose of this policy statement is to update the 2004 American Academy of Pediatrics clinical report and provide enhanced guidance for institutions, administrators, and providers in the development and operation of a pediatric intermediate care unit (IMCU). Since 2004, there have been significant advances in pediatric medical, surgical, and critical care that have resulted in an evolution in the acuity and complexity of children potentially requiring IMCU admission. A group of 9 clinical experts in pediatric critical care, hospital medicine, intermediate care, and surgery developed a consensus on priority topics requiring updates, reviewed the relevant evidence, and, through a series of virtual meetings, developed the document.

Article Synopsis
  • Anastomotic stricture is a common complication following esophageal atresia repair, and the study aimed to investigate if acid suppression after surgery could reduce the occurrence of these strictures.
  • Conducted on a cohort of 156 infants from 2016 to 2020, the study found that 51% developed strictures, with a significant proportion occurring within three months post-repair, and the use of acid suppression did not correlate with a reduction in stricture formation at various time points.
  • The analysis revealed that the use of a transanastomotic tube was linked to an increased risk of strictures at hospital discharge and at three months, indicating that this device may contribute to the complications rather than the duration

Diverse perspectives are critical components of effective teams in every industry. Underrepresentation of minorities in medicine leads to worse outcomes for minority patients, and efforts to increase diversity in the health care workforce are critical. Presently, about 70% of the pediatric surgery workforce is white, and pediatric surgeons at large do not reflect the racial or ethnic diversity of the populations they serve.

Background: The objective of our study was to describe the workup, management, and outcomes of pediatric patients with breast masses undergoing operative intervention.

Materials And Methods: A retrospective cohort study was conducted of girls 10-21 y of age who underwent surgery for a breast mass across 11 children's hospitals from 2011 to 2016. Demographic and clinical characteristics were summarized.

Background: There is growing concern regarding the impact of general anesthesia on neurodevelopment in children. Pre-clinical animal studies have linked anesthetic exposure to abnormal central nervous system development, but it is unclear whether these results translate into humans. The purpose of this systematic review from the American Pediatric Surgical Association (APSA) Outcomes and Evidence-Based Practice (OEBP) Committee was to review, summarize, and evaluate the evidence regarding the neurodevelopmental impact of general anesthesia on children and identify factors that may affect the risk of neurotoxicity.

Objective: The goal of this systematic review by the American Pediatric Surgical Association Outcomes and Evidence-Based Practice Committee was to develop recommendations for the management of ileocolic intussusception in children.

Methods: The ClinicalTrials.gov, Embase, PubMed, and Scopus databases were queried for literature from January 1988 through December 2018.

Purpose: Chest tube (CT) management for pediatric primary spontaneous pneumothorax (PSP) is associated with long hospital stays and high recurrence rates. To streamline management, we explored simple aspiration as a test to predict need for surgery.

Methods: A multi-institution, prospective pilot study of patients with first presentation for PSP at 9 children's hospitals was performed.

Background: Gastroschisis is an increasingly common congenital abdominal wall defect. Due to advances in neonatal critical care and early surgical management, mortality from gastroschisis and associated complications has decreased to less than 10% in most series. However, it has been recognized that the outcome of gastroschisis has a spectrum and that the disorder affects a heterogeneous cohort of neonates.

Background: Treatment of the neonate with long gap esophageal atresia (LGEA) is one of the most challenging scenarios facing pediatric surgeons today. Contributing to this challenge is the variability in case definition, multiple approaches to management, and heterogeneity of the reported outcomes. This necessitates a clear summary of existing evidence and delineation of treatment controversies.

Background: Omphaloceles can be some of the more challenging cases managed by pediatric surgeons. Single center studies have not been meaningful in delineating outcomes due to the length of time required to accumulate a large enough series with historical changes in management negating the results. The purpose of this study was to evaluate factors impacting the morbidity and mortality of neonates with omphaloceles.
