Background: Entrustable Professional Activities (EPAs) have emerged as a valuable tool in medical education, enabling the assessment of trainee competence in a real-world context. Despite its growing popularity in other medical specialties, the use of EPAs in pediatric surgery is still relatively new.

Methods: This article provides an overview of the development and application of EPAs in pediatric surgery.

Background: The Nuss procedure for pectus excavatum is associated with prolonged hospitalizations due to pain. We evaluated implementation of intercostal nerve cryoablation and enhanced recovery after surgery (ERAS) protocols on outcomes of Nuss procedures performed over six years at a single institution.

Methods: This retrospective cohort study included patients who underwent Nuss procedure from 10/2017 to 09/2023.

Background: Previous studies showed comparable outcomes for common in-patient general surgery operations, but it is unknown if this extends to outpatient operations. Our aim was to compare outpatient cholecystectomy outcomes between rural and urban hospitals.

Methods: A retrospective cohort analysis was done using the Nationwide Ambulatory Surgery Sample for patients 20-years-and-older undergoing cholecystectomy between 2016 and 2018 ​at rural and urban hospitals.

Among neonatal cardiomyopathies, primary endocardial fibroelastosis (pEFE) remains a mysterious disease of the endomyocardium that is poorly genetically characterized, affecting 1/5000 live births and accounting for 25% of the entire pediatric dilated cardiomyopathy (DCM) with a devastating course and grave prognosis. To investigate the potential genetic contribution to pEFE, we performed integrative genomic analysis, using whole exome sequencing (WES) and RNA-seq in a female infant with confirmed pathological diagnosis of pEFE. Within regions of homozygosity in the proband genome, WES analysis revealed novel parent-transmitted homozygous mutations affecting three genes with known roles in cilia assembly or function.

Article Synopsis
  • The RVU system, implemented by Medicare, aims to standardize payments for medical services but tends to overlook pediatric-specific procedures, which affects reimbursements from private insurers and Medicaid.
  • A study analyzed 85 pediatric surgical procedures, revealing that 74% were Peds-specific and about half of these had never been updated, compared to a higher update rate for Non-specific procedures.
  • The findings suggest that RVUs for pediatric surgeries have not been prioritized for updates, meaning they could lead to inaccurate reimbursement for pediatric surgeons since most valuation justifications are based on adult patients.

Article Synopsis
  • CMS is proposing to change how postoperative care is billed by removing it from global periods and requiring surgeons to use evaluation & management (E&M) codes, which could affect pediatric surgeons' reimbursement.
  • A study using NSQIP-pediatric data showed that most high-volume surgical procedures have a significantly lower length of stay (LOS) than current CMS values, indicating a potential reimbursement decrease for surgeons.
  • The overall impact of these changes suggests pediatric surgeons could face a reduction of about $3.4 million annually in reimbursements, raising concerns about possible effects on the quality of patient care that need further exploration.

Background: Males and females are known to have varied responses to medical interventions. Our study aimed to determine the effect of sex on surgical outcomes after pyloromyotomy.

Materials And Methods: Using the Kids' Inpatient Database for the years 2003-2012, we performed a serial, cross-sectional analysis of a nationally representative sample of all patients aged <1 y who underwent pyloromyotomy for hypertrophic pyloric stenosis.

Background: National, procedure-specific clinical registries are increasingly available in surgery, although data about children have lagged behind. Data related to the surgical management of appendicitis in children have become available recently and can be used to inform patient and family expectations and to identify clinical areas in need of ongoing improvement.

Methods: Cases of acute, uncomplicated appendicitis in children (<18 years of age) were extracted from the 2017 pediatric appendectomy-targeted file of the American College of Surgeons National Surgical Quality Improvement Program.

Background: Necrotizing soft tissue infections (NSTI) are aggressive infections associated with significant morbidity and mortality. Despite multiple predictive models for the identification of NSTI, a subset of patients will not have an NSTI at the time of surgical exploration. We hypothesized there is a subset of patients without NSTI who are clinically indistinguishable from those with NSTI.

Variations in the management of adolescents at children's hospitals (CHs) and nonchildren's hospitals (NCHs) have been well described in the trauma literature. However, the effects of CH designation on outcomes after common general surgical procedures have not been investigated. The purpose of this study was to compare the outcomes and costs of adolescent cholecystectomies performed at CHs and NCHs.

Background: There is a well-established relationship between surgical volume and outcomes after complex pediatric operations. However, this relationship remains unclear for common pediatric procedures. The aim of our study was to investigate the effect of hospital volume on outcomes after hypertrophic pyloric stenosis (HPS).

Perforated appendicitis, as defined by a visible hole in the appendix or an appendicolith free within the abdomen, carries significant morbidity in the pediatric population. Accurate diagnosis is challenging as there is no single symptom or sign that accurately predicts perforated appendicitis. Younger patients and those with increased duration of symptoms are at higher risk of perforated appendicitis.

Background: Variations in the management of pediatric patients at children's hospitals (CHs) and non-CHs (NCHs) have been well described, especially within the trauma literature. However, little is known about the outcomes and costs of common general surgical procedures at NCHs. The purpose of this study was to evaluate the effect of CH designation on the outcomes and costs of appendectomy and cholecystectomy.

Background/purpose: Despite policy efforts to support rural hospitals, little is known about the quality and safety of pediatric surgical care in geographically remote areas. Our aim was to determine the outcomes and costs of appendectomies at rural hospitals.

Methods: The Kids' Inpatient Database (2003-2012) was queried for appendectomies in children <18 years at urban and rural hospitals.

Background: The purpose of our study was to assess the outcomes and costs of appendectomies performed at rural and urban hospitals.

Methods: The National Inpatient Sample (2001-2012) was queried for appendectomies at urban and rural hospitals. Outcomes (disease severity, laparoscopy, complications, length of stay (LOS), and cost) were analyzed.

Acute appendicitis is a common nonobstetric indication for surgical intervention during pregnancy with serious potential complications for the mother and fetus. The aim of this study was to evaluate the presentation, management practices, outcomes, and costs of appendectomy during pregnancy. We did a retrospective analysis of 62,118 nonincidental appendectomies performed in women (age 15-45 years) identified from the California State Inpatient Database (2005-2011).

Background: The study of regional variations in surgical outcomes and cost has been used to identify areas for improvement and savings. This study investigates potential regional differences in the outcomes and cost of adult appendicitis. We hypothesized that there would be no difference in rates of laparoscopy, perforation, morbidity, length of stay (LOS), and cost among different regions of the United States.

We evaluated the outcomes for nonoperative management (NOM) of all children with suspected nonperforated appendicitis, including those patients with an appendicolith. Parents of all children with suspected nonperforated appendicitis were offered NOM versus laparoscopic appendectomy. NOM included administration of intravenous antibiotics and hospital admission.
