With improvements in initial care for patients with congenital diaphragmatic hernia (CDH), the number of CDH patients with severe disease who are surviving to discharge has increased. This growing population of patients faces a unique set of long-term challenges, multisystem adverse outcomes, and post-intervention complications requiring specialized multidisciplinary follow-up. Early identification and intervention are essential to mitigate the potential morbidity associated with these challenges.

Extracorporeal life support (ECLS) serves as a rescue therapy for patients with congenital diaphragmatic hernia (CDH) and severe cardiopulmonary failure, and only half of these patients survive to discharge. This costly intervention has a significant complication risk and is reserved for patients with the most severe disease physiology refractory to maximal cardiopulmonary support. Some contraindications to ECLS do exist such as coagulopathy, lethal chromosomal or congenital anomaly, very preterm birth, or very low birth weight, but many of these limits are being evaluated through further research.

Objectives: Literature is emerging regarding the role of center volume as an independent variable contributing to improved outcomes. A higher volume of index procedures may be associated with decreased morbidity and mortality. This association has not been examined for the subgroup of infants with congenital diaphragmatic hernia (CDH) receiving extracorporeal life support (ECLS).

Although used commonly, ability of inhaled nitric oxide (iNO) to improve outcomes in infants with congenital diaphragmatic hernia (CDH) who receive extracorporeal life support (ECLS) remains controversial. We sought to determine the association between pre-ECLS use of iNO and mortality in infants with CDH from the Extracorporeal Life Support Organization (ELSO) Registry. Neonates who underwent ECLS for CDH were identified from the ELSO Registry from 2009 to 2019.

Congenital diaphragmatic hernia (CDH) is a challenging surgical disease that requires complex preoperative, perioperative, and postoperative care. Survival depends on successful reduction and repair of the defect, and numerous complex decisions must be made regarding timing and preparation for surgery. This review describes the challenges and controversies inherent to surgical CDH care and provides recommendations for management based on the most recent evidence.

Congenital diaphragmatic hernia (CDH) is a rare birth defect characterized by incomplete closure of the diaphragm and herniation of fetal abdominal organs into the chest that results in pulmonary hypoplasia, postnatal pulmonary hypertension owing to vascular remodelling and cardiac dysfunction. The high mortality and morbidity rates associated with CDH are directly related to the severity of cardiopulmonary pathophysiology. Although the aetiology remains unknown, CDH has a polygenic origin in approximately one-third of cases.

Article Synopsis
  • The study aimed to analyze mortality rates of infants with congenital diaphragmatic hernia (CDH) on extracorporeal life support (ECLS) across different medical centers using standardized mortality ratios (SMRs).
  • Data from the Extracorporeal Life Support Organization registry (2000-2019) was utilized, revealing significant variations in mortality rates, with some centers performing better and others worse compared to the median rate.
  • The findings highlight 13 centers with significantly better outcomes and 7 with worse outcomes, suggesting the need for further investigation into successful treatment strategies to enhance overall care for infants with CDH.

Introduction: Upper gastrointestinal (UGI) pathologies are common in adolescents with obesity. This study aims to determine the prevalence of UGI inflammation on preoperative esophagogastroduodenoscopy (EGD) in adolescents undergoing sleeve gastrectomy (SG) and to assess weight loss outcomes.

Methods: This is a retrospective analysis of pathology reports from EGD biopsies performed prior to SG from September 2017 to August 2020.

Background: The care of patients with congenital diaphragmatic hernia (CDH) is expensive, yet little is known about variability in cost-of-care for these patients. The purpose of this study was to examine the cost-effectiveness of CDH treatment, comparing high- versus low-volume centers.

Methods: This is a retrospective study of neonatal patients with CDH at U.

Article Synopsis
  • Congenital diaphragmatic hernia (CDH) is a serious condition in newborns that can be fatal, and this study compares outcomes for babies delivered at the hospital providing specialized care (inborn) versus those delivered elsewhere (outborn).
  • From 2007 to 2019, data from 4,195 neonates with prenatally diagnosed CDH were analyzed, revealing no significant differences in mortality rates (32.6% vs. 33.8%) or the need for extracorporeal life support (ECLS) between inborn and outborn infants.
  • Although outborn infants requiring ECLS initially showed higher mortality risk, this factor was no longer significant when considering the size of their surgical

Background: Neonates receiving extracorporeal life support (ECLS) for congenital diaphragmatic hernia (CDH) require prolonged support compared with neonates with other forms of respiratory failure. Hemolysis is a complication that can be seen during ECLS and can lead to renal failure and potentially to worse outcomes. The purpose of this study was to identify risk factors for the development of hemolysis in CDH patients treated with ECLS.

The management of infants with congenital diaphragmatic hernia (CDH) receiving extracorporeal life support (ECLS) is complex. Significant variability in both practice and prevalence of ECLS use exists among centers, given the lack of evidence to guide management decisions. The purpose of this report is to review existing evidence and develop management recommendations for CDH patients treated with ECLS.

Background: Anorectal malformations (ARMs) have a wide spectrum of presentation ranging from mild defects with perineal fistulas to more severe defects requiring complex management. A primary repair of ARMs with perineal or rectovestibular fistulas has been shown to have good outcomes. However, the timing of the reconstruction is still debated.

Background: Although longer ECMO run times for patients with congenital diaphragmatic hernia (CDH) have been associated with worse outcomes, a large study has not been conducted to examine the risk factors for long ECMO runs.

Methods: The Extracorporeal Life Support Organization (ELSO) Registry from 2000 to 2015 was used to identify predictors of long ECMO runs in CDH patients. A long run was any duration of ≥14 days.

Article Synopsis
  • The study explores the relationship between congenital diaphragmatic hernia (CDH) and the risk of multiorgan dysfunction (MOD) in infants treated with extracorporeal membrane oxygenation (ECMO), noting a high mortality rate of 52.4%.
  • Researchers analyzed data from the Extracorporeal Life Support Organization database, focusing on factors like pre-ECMO cardiac arrest and bagging procedures, which were found to significantly increase the risk of MOD.
  • The findings suggest that improving pre-ECMO support and initiating ECMO before cardiac arrest could reduce the chances of developing complications like MOD.

Because congenital diaphragmatic hernia (CDH) is characterized by a spectrum of severity, risk stratification is an essential component of care. In both the prenatal and postnatal periods, accurate prediction of outcomes may inform clinical decision-making, care planning, and resource allocation. This review examines the history and utility of the most well-established risk prediction tools currently available, and provides recommendations for their optimal use in the management of CDH patients.

Objective: The goal of this systematic review by the American Pediatric Surgical Association Outcomes and Evidence-Based Practice Committee was to derive recommendations from the medical literature regarding the management of pilonidal disease.

Methods: The PubMed, Cochrane, Embase, Web of Science, and Scopus databases from 1965 through June 2017 were queried for any papers addressing operative or non-operative management of pilonidal disease. The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines were followed.

Purpose: Studying the timing of repair in CDH is prone to confounding factors, including variability in disease severity and management. We hypothesized that delaying repair until post-ECMO would confer a survival benefit.

Methods: Neonates who underwent CDH repair were identified within the ELSO Registry.
