Biliary atresia is a progressive cholangiopathy in neonates, which often results in liver failure. In high-income countries, initial treatment requires prompt diagnosis followed by Kasai portoenterostomy. For those with a late diagnosis, or those in whom Kasai portoenterostomy fails, liver transplantation is the only lifesaving treatment.

Background: Choledochal cysts are rare congenital anomalies of the biliary tree that may lead to obstruction, chronic inflammation, infection, and malignancy. There is wide variation in the timing of resection, operative approach, and reconstructive techniques. Outcomes have rarely been compared on a national level.

Maternal-fetal surgical interventions have become a more common part of prenatal care. This third option, beside termination or post-natal interventions, complicates prenatal decision-making: while interventions may be lifesaving, survivors may face a life with disability. Pediatric palliative care (PPC) is more than end of life or hospice care, it aims at helping patients with complex medical conditions live well.

Background: Omental cysts are rare, predominantly occur in children, and often initially present with symptoms masquerading as other more common intra-abdominal pathologies. In this case report, we present the case of a child with an omental cyst that originated from the lesser sac. Due to the location of this cyst, resection presented unique technical challenges that have not been described in existing literature.

Objectives: To characterize patterns of surgery among pediatric patients during terminal hospitalizations in children's hospitals.

Methods: We reviewed patients ≤20 years of age who died among 4 424 886 hospitalizations from January 2013-December 2019 within 49 US children's hospitals in the Pediatric Health Information System database. Surgical procedures, identified by International Classification of Diseases procedure codes, were classified by type and purpose.

Pediatric surgeons play an essential role in prenatal consultation for congenital anomalies likely to require surgery in the newborn period. The involvement of pediatric surgeons during multi-disciplinary prenatal meetings has been an important part of the evolution of comprehensive fetal care, characterized by detailed prenatal evaluation, diagnosis, prognosis, and planned perinatal and post-natal care. Advances in fetal diagnostics and treatments, as well as complex postnatal medical care and decision-making create a broad range of care options for pregnant women with fetal surgical anomalies.

Background And Objectives: The coronavirus disease 2019 (COVID-19) pandemic has led to changes in health care use, including decreased emergency department visits for children. In this study, we sought to describe the impact of the COVID-19 pandemic on inpatient use within children's hospitals.

Methods: We performed a retrospective study using the Pediatric Health Information System.

Purpose: To determine if there is a role for routine pouchogram before ileostomy reversal after IPAA in pediatric patients.

Methods: The medical records of pediatric patients who underwent pouchogram between 2007 and 2017 prior to ileostomy reversal after IPAA at two affiliated hospitals were reviewed for concordance between exam under anesthesia (EUA) and pouchogram findings, management of abnormal pouchogram findings, and short and long-term outcomes after ileostomy reversal. Clinical notes were used to find patient-reported symptoms at the time of pouchogram.

Objective: The Management of Myelomeningocele Study (MOMS) compared prenatal with postnatal surgery for myelomeningocele (MMC). The present study sought to determine how MOMS influenced the clinical recommendations of pediatric neurosurgeons, how surgeons' risk tolerance affected their views, how their views compare to those of their colleagues in other specialties, and how their management of hydrocephalus compares to the guidelines used in the MOMS trial.

Methods: A cross-sectional survey was sent to all 154 pediatric neurosurgeons in the American Society of Pediatric Neurosurgeons.

Uptake of prenatal genetic testing (PGT) is low among those with sickle cell disease (SCD). This study evaluated the association of knowledge and attitudes towards prenatal genetic counseling (PGC), awareness of posttesting intervention options and omission bias with attitudes towards PGT. In addition, we explored changes among knowledge, attitudes, and awareness of options following exposure to an educational, clinical vignette among parents of children with SCD.

Physicians play a key role in implementing health policy, and US physicians were split in their opinions about the Affordable Care Act (ACA) soon after its implementation began. We readministered elements of a prior survey of US physicians to a similar sample to understand how US physicians' opinions of the ACA may have changed over a crucial five-year implementation period (2012-17), and we compared responses across both surveys. Of the 1,200 physicians to whom we sent a survey in the summer of 2017, 489 responded (a response rate of 41 percent).

Context: Do-not-resuscitate (DNR) orders are common among children receiving palliative care, who may nevertheless benefit from surgery and other procedures. Although anesthesia, surgery, and pediatric guidelines recommend systematic reconsideration of DNR orders in the perioperative period, data regarding how clinicians evaluate and manage DNR orders in the perioperative period are limited.

Objectives: To evaluate perioperative management of DNR orders at a tertiary care children's hospital.

Background: Prenatal surgery for myelomeningocele (MMC) has been demonstrated to have benefits over postnatal surgery. Nevertheless, prenatal surgery requires a significant emotional, physical, and financial commitment from the entire family.

Methods: Mixed methods study of parents' perceptions regarding provider communication, treatment choices, and the family impact of having a child with MMC.

Objectives: The ethics of maternal-fetal surgery involves weighing the importance of potential benefits, risks, and other consequences involving the pregnant woman, fetus, and other family members. We assessed clinicians' ratings of the importance of 9 considerations relevant to maternal-fetal surgery.

Methods: This study was a discrete choice experiment contained within a 2015 national mail-based survey of 1200 neonatologists, pediatric surgeons, and maternal-fetal medicine physicians, with latent class analysis subsequently used to identify groups of physicians with similar ratings.

Introduction: Supraglottic airway (SGA) use and outcomes in pediatric trauma are poorly understood. We compared outcomes between patients receiving prehospital SGA versus bag mask ventilation (BVM).

Methods: We reviewed pediatric multisystem trauma patients (2005-2016), comparing SGA and BVM.

Purpose: The purpose of this study was to evaluate the impact of impaired growth on short-term neurodevelopmental (ND) outcomes in CDH survivors.

Methods: Between 9/2005-12/2014, 84 of 215 (39%) CDH survivors underwent ND assessment at 12months of age using the BSID-III.

Results: Mean cognitive, language, and motor scores were 92.

Background: While prenatal surgery historically was performed exclusively for lethal conditions, today intrauterine surgery is also performed to decrease postnatal disabilities for non-lethal conditions. We sought to describe physicians' attitudes about prenatal surgery for lethal and non-lethal conditions and to elucidate characteristics associated with these attitudes.

Methods: Survey of 1200 paediatric surgeons, neonatologists and maternal-fetal medicine specialists (MFMs).

The field of maternal-fetal intervention is rapidly evolving with new technologies and innovations. This raises complex ethical and medico-legal challenges related to what constitutes innovative treatment versus human experimentation, with or without the umbrella of "medical research." There exists a gray zone between these black and white classifications, but there are also clear guidelines that should be responsibly negotiated when making the essential transition between an innovative treatment and a validated therapy.

Background: In utero hematopoietic cell transplantation (IUHCT) has curative potential for sickle cell disease (SCD) but carries a risk of fetal demise.

Methods: We assessed the conditions under which parents of children with SCD and young adults with SCD would consider IUHCT in a future pregnancy, given a 5% fixed risk of fetal demise. Participants were randomized to consider a hypothetical cure rate (20%, 40%, or 70%).
