Management of Acute Wounds - Expert Panel Consensus Statement.

SIGNIFICANCE: The Wound Healing Foundation recognized the need for consensus-based unbiased recommendations for the treatment of wounds. As a first step, a consensus on the treatment of chronic wounds was developed and published in 2022.(1) The current publication on acute wounds represents the second step in this process. Acute wounds may result from any number of conditions, including burns, military and combat operations, and trauma to specific areas of the body. The management of acute wounds requires timely and evidence-driven intervention to achieve optimal clinical outcomes. This consensus statement provides the clinician with the necessary foundational approaches to the causes, diagnosis and therapeutic management of acute wounds. Presented in a structured format, this is a useful guide for clinicians and learners in all patient care settings. RECENT ADVANCES: Recent advances in the management of acute wounds have centered on stabilization and treatment in the military and combat environment, Specifically advancements in hemostasis, resuscitation, and the mitigation of infection risk through timely initiation of antibiotics and avoidance of high pressure irrigation in contaminated soft tissue injury. . CRITICAL ISSUES: Critical issues include infection control, pain management and the unique considerations for the management of acute wounds in pediatric patients. FUTURE DIRECTIONS: Future directions include new approaches to preventing the progression and conversion of burns through the use of the microcapillary gel, a topical gel embedded with the anti-inflammatory drug infliximab.(38) Additionally, the use of three-dimensional bioprinting and photo-modulation for skin reconstruction following burns is a promising area for continued discovery.

The Pathophysiology and Management of Pathologic Scarring-a Contemporary Review.

Significance: Pathologic scarring occurs secondary to imbalances in the cellular mechanisms of wound healing and affects millions of people annually. This review article aims to provide a concise overview of the pathophysiology and management of pathologic scarring for clinicians and scientists alike. Recent Advances: Contemporary research in the field has identified aberrations in transforming growth factor-ß/small mothers against decapentaplegic (TGF-ß/SMAD) signaling pathways as key drivers of pathologic scar formation; indeed, this pathway is targeted by many treatment modalities and translational investigations currently underway. Although intralesional injection of corticosteroids has been the gold standard in the treatment of pathologic scarring, studies show greater treatment efficacy with the use of combination injections such as triamcinolone/5-fluorouracil and triamcinolone/botulinum toxin. Adjunctive therapies including ablative fractional carbon dioxide/erbium-doped yttrium aluminum garnet and non-ablative pulsed-dye lasers, microneedling, and carboxytherapy have shown encouraging results in small cohort studies. Translational investigations involving the use of nanogels, RNA interference, and small molecules targeting TGF-ß/SMAD pathways are also currently underway and hold promise for the future. Critical Issues: The heterogeneous nature of hypertrophic scars and keloids poses significant challenges in formulating standardized treatment and assessment protocols, thereby limiting the conclusions that can be drawn. Future Directions: Rigorous clinical trials into the individual and synergistic effects of these therapies would be ideal before any definitive conclusions or evidence-based treatment recommendations can be made. Owing to the heterogeneity of the pathology and patient population, well-conducted cohort studies may be the next best option.

Surfactant Therapy in Congenital Diaphragmatic Hernia and Fetoscopic Endoluminal Tracheal Occlusion.

INTRODUCTION: Congenital diaphragmatic hernia (CDH) is a complex pathology with severe pulmonary morbidity. Administration of surfactant in CDH is controversial, and the advent of fetoscopic endoluminal tracheal occlusion (FETO) has added further complexity. While FETO has been shown to improve survival outcomes, there are risks of prematurity and potential surfactant deficiency. We aim to evaluate the characteristics and outcomes of surfactant administration for CDH infants and elucidate potential benefits or risks in this unique population. METHODS: A single-center retrospective cohort review of patients with unilateral CDH from September 2015 to July 2022 was performed. Demographics, prognostic perinatal imaging features, and outcomes were collected. Patients were stratified by surfactant administration and history of FETO. Data were analyzed with descriptive statistics, two-sample t-tests, chi-squared analyses, and logistic regression. RESULTS: Of 105 included patients, 19 (18%) underwent FETO and 25 (24%) received surfactant. Overall, surfactant recipients were born at earlier gestational ages and lower birthweights regardless of FETO history. Surfactant recipients possessed significantly worse prenatal prognostic features such as observed to expected total fetal lung volume, observed to expected lung to head ratio, and percent liver herniation. In CDH patients without FETO history, surfactant recipients demonstrated worse outcomes than nonrecipients. This association is notably absent in the FETO population, where surfactant recipients have more favorable survival and comparable outcomes. When controlling for defect severity or surfactant usage, as a proxy for respiratory status, surfactant recipients that underwent FETO trended toward improved survival and decreased ECMO use. CONCLUSIONS: Surfactant administration is not associated with increased morbidity and mortality and may be beneficial in CDH patients that have undergone FETO.

Molecular insights using spatial transcriptomics of the distal lung in congenital diaphragmatic hernia.

Abnormal pulmonary vascular development and function in congenital diaphragmatic hernia (CDH) is a significant factor leading to pulmonary hypertension. The lung is a very heterogenous organ and has marked cellular diversity that is differentially responsive to injury and therapeutic agents. Spatial transcriptomics provides the unmatched capability of discerning the differences in the transcriptional signature of these distinct cell subpopulations in the lung with regional specificity. We hypothesized that the distal lung parenchyma (selected as a region of interest) would show a distinct transcriptomic profile in the CDH lung compared with control (normal lung). We subjected lung sections obtained from male and female CDH and control neonates to spatial transcriptomics using the Nanostring GeoMx platform. Spatial transcriptomic analysis of the human CDH and control lung revealed key differences in the gene expression signature. Increased expression of alveolar epithelial-related genes (SFTPA1 and SFTPC) and angiogenesis-related genes (EPAS1 and FHL1) was seen in control lungs compared with CDH lungs. Response to vitamin A was enriched in the control lungs as opposed to abnormality of the coagulation cascade and TNF-alpha signaling via NF-kappa B in the CDH lung parenchyma. In male patients with CDH, higher expression of COL1A1 (ECM remodeling) and CD163 was seen. Increased type 2 alveolar epithelial cells (AT-2) and arterial and lung capillary endothelial cells were seen in control lung samples compared with CDH lung samples. To the best of our knowledge, this is the first use of spatial transcriptomics in patients with CDH that identifies the contribution of different lung cellular subpopulations in CDH pathophysiology and highlights sex-specific differences.NEW & NOTEWORTHY This is the first use of spatial transcriptomics in patients with congenital diaphragmatic hernia (CDH) that identifies the contribution of different lung cellular subpopulations in CDH pathophysiology and highlights sex-specific differences.

Percutaneous versus Open Fetal Surgical Intervention for Sacrococcygeal Teratomas: Is Less Really More?

INTRODUCTION: Sacrococcygeal teratomas (SCTs) may require in utero intervention for survival. Open surgical intervention (OSI) was first described, but increasing reports of percutaneous intervention (PI) with variable indications and outcomes exist. We reviewed the literature for all published cases of fetal SCT intervention and compared OSI to PI cohorts. METHODS: A keyword search of PubMed was conducted. Inclusion criteria were as follows: data available per individual fetus including gestational age at intervention, type of intervention, primary indication, survival, gestational age at birth, and complications. Complications were grouped into categories: placenta/membrane, procedural, or hemorrhagic. Failure was defined as little/no improvement or recurrence of the primary indication. χ2 analysis was performed for solid tumor PI versus OSI to assess significant trends in these intervention groups. A meta-analysis was not feasible due to small numbers and heterogeneity. RESULTS: Twenty-seven articles met inclusion criteria. In the PI group, 38 fetuses underwent intervention for solid tumors, 21 for cystic tumors, and 3 for solid and cystic tumor components. Among fetuses with solid tumors, OSI was associated with lower need for multiple interventions (0% vs. 31.6%, p = 0.01) and higher survival to discharge (50% vs. 39.5%, p = 0.02). A fetal intervention was performed in the absence of hydrops/early hydrops in 45% of fetuses receiving PI, compared to 21% receiving OSI. Failure to resolve the primary indication was higher in the PI group (55.9% vs. 11.1% OSI, p = 0.02). The overall complication rates were high in both groups (90% OSI, 87% PI), though bleeding was unique to the PI group (26.5%). Preemptive cyst drainage, for purely cystic tumors, was universally successful and associated with a low complication risk (18.2%). CONCLUSIONS: For solid tumors, OSI appears to be superior with regard to survival to discharge, fewer interventions, and lower failure rates. PIs to drain a cyst may facilitate delivery or preempt future complications, though consideration should be given to long-term oncologic outcomes.

An Accountable Care Organization Maintains Access for Appendicitis During the COVID-19 Pandemic.

INTRODUCTION: It has been reported that pediatric patients experienced a delay in treatment for acute appendicitis during the pandemic, resulting in increased rates of complicated appendicitis. We investigated the association of the COVID-19 pandemic and the incidence and severity of acute appendicitis among pediatric Medicaid patients using a population-based approach. METHODS: The claims database of Partners For Kids, a pediatric Medicaid accountable care organization (ACO) in Ohio, was queried for cases of acute appendicitis from April to August 2017-2020. The monthly rate of acute appendicitis/100,000 covered lives was calculated each year and compared over time. Rates of complicated appendicitis were also compared. Diagnosis code validation for classification as complicated or uncomplicated appendicitis was performed for patients treated at our hospital. RESULTS: During the study period, 465 unique cases of acute appendicitis were identified. Forty percent (186/465) were coded as complicated. No significant difference in the incidence of acute appendicitis cases was observed across the 4 y, either in an overall comparison or in pairwise comparisons (P > 0.15 for all). The proportion of acute appendicitis cases that were coded as complicated did vary significantly over the 4-year study period (P = 0.005); this was due to this proportion being significantly higher in 2018 than in either 2019 (P = 0.005 versus 2018) or 2020 (P = 0.03 versus 2018). CONCLUSIONS: The COVID-19 pandemic was not associated with reduced access to treatment for acute appendicitis among patients in a pediatric Medicaid ACO. This suggests that an ACO may promote continued healthcare access for their covered population during an unexpected crisis.

Giant Omphaloceles-Morbidity, Mortality, and Financial Impact of Early Versus Delayed Repair.

INTRODUCTION: We compared strategy outcomes and financial impact over the first two years of life (F2YOL) for patients with giant omphaloceles undergoing early repair (ER) (primary or staged) versus delayed repair (DR). METHODS: A retrospective review of giant omphaloceles (fascial defect > 5 cm/> 50% liver herniation) at a tertiary children's hospital between 1/1/2010 and 12/31/2019 was performed. Survival, length of stay, age at repair, ventilation days (VD), time to full enteral feeds, readmissions during the F2YOL, incidence of major associated anomalies, and total hospitalization charges during the F2YOL were compared. A subanalysis removing potential confounders and only including patients who underwent fascial closure within the F2YOL was also conducted. RESULTS: Thirty four giant omphaloceles (23DR and 11ER) were identified. The median age (days) at repair was 289 [148, 399] DR versus 10 [5, 21] ER, P < 0.001. Total cohort two-year survival was significantly higher in the DR group (95.7% versus 63.6%, P = 0.03). Including patients with a tracheostomy there was no significant difference in VD during the index hospitalization. Excluding tracheostomy patients, the DR group had significantly fewer VD during the index hospitalization, 15 [0, 15] versus 18 [10, 54], P = 0.02 and over the F2YOL 6.5 [ 0, 21] versus 18 [14, 43], P = 0.03. There were no significant differences in the incidence/type of major associated anomalies, time to full enteral feeds, index length of stay, total hospital days, total admissions, or associated hospital charges. On subanalysis, there was no significant difference in VD or survival at any time. CONCLUSIONS: Delayed and early repair strategies for giant omphaloceles have equivalent outcomes in the index hospitalization and over the course of the first two years of life. These findings are useful for family counseling and expectation setting.

Establishing a Fetal Center in a Freestanding Pediatric Hospital.

Advances in antenatal imaging have allowed early and accurate diagnosis of many fetal anomalies. This, together with the increasing understanding of the natural history of many fetal diseases, has opened the door to the possibility of offering timely fetal interventions in progressive or life-threatening conditions with the intention of improving perinatal outcomes. These interventions can occur at an adult hospital with obstetrical services (with or without pediatric care) or at a freestanding pediatric hospital. In this article, we provide an overview of the approach to develop a comprehensive fetal care center in a freestanding pediatric hospital. Services included prenatal consultation, advanced diagnostics, innovative fetal therapy, research, and special delivery services. We also review the importance of continuous improvement in achieving this goal.

A Systematic Review of Clinical Outcomes After Carotid Artery Ligation Versus Carotid Artery Reconstruction Following Venoarterial Extracorporeal Membrane Oxygenation in Infants and Children.

INTRODUCTION: In pediatric and neonatal populations, the carotid artery is commonly cannulated for venoarterial (VA) extracorporeal membrane oxygenation (ECMO). The decision to ligate (carotid artery ligation [CAL]) versus reconstruct (carotid artery reconstruction [CAR]) the artery at decannulation remains controversial as long-term neurologic outcomes remain unknown. The objective of this study was to summarize current literature on clinical outcomes following CAL and CAR after Venoarterial Extracorporeal Membrane Oxygenation (VA-ECMO). METHODS: PubMed (MEDLINE), Embase, Web of Science, and Cochrane databases were searched using keywords from January 1950 to October 2020. Studies examining clinical outcomes following CAL and CAR for VA-ECMO in patients <18 y of age were included. Prospective and retrospective cohort studies, case series, case-control studies, and case reports were included. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were performed independently by two reviewers. Assessment of risk of bias was performed. RESULTS: Eighty studies were included and classified into four categories: noncomparative clinical outcomes after CAL (n = 23, 28.8%), noncomparative clinical outcomes after CAR (n = 12, 15.0%), comparative clinical outcomes after CAL and/or CAR (n = 28, 35.0%), and case reports of clinical outcomes after CAL and/or CAR (n = 17, 21.3%). Follow-up ranged from 0 to 11 y. CAR patency rates ranged from 44 to 100%. There was no substantial evidence supporting an association between CAL versus CAR and short-term neurologic outcomes. CONCLUSIONS: Studies evaluating outcomes after CAL versus CAR for VA-ECMO are heterogeneous with limited generalizability. Further studies are needed to evaluate long-term consequences of CAL versus CAR, especially as the first survivors of pediatric/neonatal ECMO approach an age of increased risk of carotid stenosis and stroke.

Serum Amyloid P Attenuates Hypertrophic Scarring in Large Animal Models.

INTRODUCTION: This study's purpose was to (1)determine the effect of locally administered serum amyloid P (SAP) on the development of hypertrophic scars (HTS) in porcine and rabbit HTS models and (2)determine the pharmacokinetics of systemically administered SAP and its effect on circulating fibrocyte quantities. METHODS: Two large animal (New Zealand White Rabbit and Female Red Duroc Pigs) HTS models were utilized to study the effects of daily local injections of SAP immediately post wounding (x5 d in rabbits; x7 d in pigs) on HTS development as measured by scar elevation index , scar area, wound closure, and molecular expression studies of scar components. For SAP pharmacokinetics, total and human SAP levels in porcine blood were measured at regular intervals following intravenous administration of human SAP. Fibrocyte quantities were determined prior to and 1 h following human SAP intravenous administration. RESULTS: In the rabbit model, local SAP significantly decreased the level of tissue inhibitor of metalloproteinases-1 mRNA expression and maintained matrix mettaloproteinase-9 expression, while control and vehicle groups significantly declined. In the pig model, there was a significant decrease in the trend of scar elevation indexes treated with local SAP versus controls over the study period. This decrease was statistically significant at days 14 and 84. Human SAP administered intravenously is degraded within 24 h and does not influence circulating fibrocyte quantities. CONCLUSIONS: This is the first study to demonstrate attenuation of HTS formation using locally administered SAP in large animal HTS models. Local SAP administration reduces HTS formation by maintaining matrix mettaloproteinase-9 and decreasing tissue inhibitor of metalloproteinases-1. Intravenous administration of SAP is not as effective.

Fetal malrotation with midgut volvulus: Prenatal diagnosis and planning.

Introduction: Malrotation of the intestinal tract is a congenital malformation commonly found either incidentally or after affected individuals develop signs and symptoms of intestinal obstruction. Malrotation is prone to midgut volvulus that can cause intestinal obstruction and lead to ischemia and necrosis requiring emergent surgical intervention. Rare instances of in utero midgut volvulus have been reported in the literature and carry a high mortality given the difficulty in establishing a diagnosis prior to development of signs of intestinal ischemia and necrosis. Advancements in imaging have made it possible to diagnose in utero malrotation earlier, raising the question of optimal timing of delivery, especially in cases of prenatally diagnosed midgut volvulus. In these cases, the risks of premature birth must be weighed against the risks of fetal intestinal ischemia and potential fetal demise. Case presentation: This case report details an interesting presentation of intestinal malrotation with suspected midgut volvulus found on prenatal imaging at 33 weeks and 4 days' gestation. This prompted delivery of the infant at 34 weeks and 2 days' gestation with urgent operative management, within 3 hours of life, after diagnosis was confirmed postnatally. Intraoperatively, the infant was confirmed to have midgut volvulus without bowel ischemia, the intestines were reduced, and a Ladd procedure was performed without incident. The infant recovered postoperatively without complication, tolerated advancement to full volume feeds and was discharged on day of life 18. Conclusion: Successful management of fetal malrotation with midgut volvulus may be accomplished by early access to a multi-disciplinary team of professionals, prompt postnatal confirmation of diagnosis, and urgent correction to minimize the risk of complications.

Association for Academic Surgery/Society of University Surgeons research awards are highly successful in fostering future surgeon-scientists.

BACKGROUND: The surgeon-scientist brings a unique perspective to surgical research. The Association of Academic Surgeons and Society of University Surgeons foster the development of surgeon-scientists through foundation awards to residents and junior faculty. We sought to evaluate the academic success of surgeons who received an Association for Academic Surgery/Society of University Surgeons award. METHODS: Information was collected for individuals who received a resident or junior faculty research award from the Association for Academic Surgery or Society of University Surgeons. Google Scholar, Scopus, and the National Institutes of Health Research Portfolio Online Reporting Tools: Expenditures and Results were used to assess scholarly achievements. RESULTS: Eighty-two resident awardees were included, 31 (38%) of whom were female. Thirteen (24%) are now professors, 12 (22%) are division chiefs, and 4 (7%) are department chairs. Resident awardees have a median of 886 citations (interquartile range 237-2,111) and an H-index of 14 (interquartile range 7-23). Seven (13%) went on to receive K08/K23 awards, and 7 (13%) received R01s, with a total of about $200 million in National Institutes of Health funding (79-fold return on investment). Thirty-four junior faculty awardees were included, 10 (29%) of whom were female. Thirteen (38%) are now professors, 12 (35%) are division chiefs, and 7 (21%) are department chairs. Faculty awardees have a median of 2,617 citations (interquartile range 1,343-7,857) and an H-index of 25 (interquartile range 18-49). Four (12%) received K08 or K23 awards, and 10 (29%) received R01s, with about $139 million in National Institutes of Health funding (98-fold return on investment). CONCLUSION: Association for Academic Surgery/Society of University Surgeons research awardees experience high degrees of success in academic surgery. Most resident awardees pursue fellowship training and remain in academic surgery. A high percentage of both faculty and resident awardees hold leadership positions and successfully achieve National Institutes of Health funding.

Inhaled Nitric Oxide and Higher Necrotizing Enterocolitis Rates in Congenital Heart Disease Patients.

INTRODUCTION: Certain congenital cardiac lesions are at increased risk for the development of necrotizing enterocolitis (NEC). These patients are often reliant on pulmonary and systemic vasomodulators to maintain adequate perfusion and oxygenation. This study sought to determine whether pulmonary or systemic vasodilator treatment is protective against the development of NEC in this population. METHODS: We utilized International Classification of Diseases (ICD) codes to identify high risk congenital cardiac disease patients ≤6 mo of age, cared for at a tertiary children's hospital between January 2011 and January 2021. Cardiac anomalies were stratified into ductal dependent (pulmonary DD-P or systemic DD-S) or independent lesions. The rate of NEC development in those who received vasodilators (inhaled nitric oxide [iNO], pulmonary vasodilators, systemic vasodilators) was compared to controls in a multivariate analysis. RESULTS: Of the 352 patients, who met inclusion criteria, 77.6% had ductal dependent lesions (DD-S 41.9%, DD-P 35.7%), 19.5% received iNO, and 37.5% received other vasodilatory drugs. The overall NEC rate was 15.1%. On univariate analysis, DD-S, iNO use, and systemic vasodilators was associated with a significantly higher risk of NEC, while DD-P was associated with lower NEC risk. On multivariate analysis, only iNO (odds ratio 2.725, confidence interval [1.36-5.44]) and DD-S (odds ratio 2.279, confidence interval [1.02-5.11]) were independent risk factors for NEC. CONCLUSIONS: In patients with at-risk congenital cardiac disease lesions, a ductus dependent systemic circulation or iNO treatment is associated with an increased risk of developing NEC. The presence of iNO or DD-S should be utilized as markers of increased risk both in the prevention and workup of suspected NEC.

Endogenous Interleukin-10 Contributes to Wound Healing and Regulates Tissue Repair.

INTRODUCTION: Interleukin-10 (IL-10) is essential in fetal regenerative wound healing and likewise promotes a regenerative phenotype in adult dermal wounds. However, the role of endogenous IL-10 in postnatal dermal wound healing is not well-established. We sought to determine the function of endogenous IL-10 in murine full thickness excisional wounds that are splinted to prevent contracture and mimic human patterns of wound closure. METHODS: Full-thickness excisional wounds were made in wildtype (WT) and IL-10-/- mice on a C57BL/6J background (F/M, 8 wk old). In a subset of wounds, contraction was prevented by splinting with silicone stents (stenting) and maintaining a moist wound microenvironment using a semiocclusive dressing. Wounds were examined for re-epithelialization, granulation tissue deposition, and inflammatory cell infiltrate at day 7 and fibrosis and scarring at day 30 postwounding. RESULTS: We observed no difference in wound healing rate between WT and IL-10-/- mice in either the stented or unstented group. At day 7, unstented IL-10-/- wounds had a larger granulation tissue area and more inflammatory infiltrate than their WT counterparts. However, we did observe more F4/80+ cell infiltrate in stented IL-10-/- wounds at day 7. At day 30, stented wounds had increased scar area and epithelial thickness compared to unstented wounds. CONCLUSIONS: These data suggest that endogenous IL-10 expression does not alter closure of full thickness excisional wounds when wound hydration and excessive contraction of murine skin are controlled. However, the loss of IL-10 leads to increased inflammatory cell infiltration and scarring. These new findings suggest that IL-10 contributes to the regulation of inflammation without compromising the healing response. These data combined with previous reports of increased rates of healing in IL-10-/- mice wounds not controlled for hydration and contraction suggest an important role for murine wound healing models used in research studies of molecular mechanisms that regulate healing.

A Review of Covered Abdominal Wall Defects: Cord Hernias Are Associated With Major Anomalies.

INTRODUCTION: Covered abdominal wall defects (CAWD) can be categorized into giant omphaloceles (GOs), nongiant omphaloceles (NGOs), and umbilical cord hernias (UCHs). We sought to evaluate differences in management and outcomes of the different CAWD, treated at a large tertiary children's hospital, with regards to survival and association with other major congenital anomalies. METHODS: A retrospective review of CAWD patients between January 2010 and January 2021 was conducted. GO was defined as a fascial defect >5 cm or >50% liver herniation. UCH were defined as fascial defects ≤ 2 cm. All others were classified as NGO. Type of repair, time to fascial closure, index hospitalization length of stay (LOS), and survival rates were compared. Four major anomaly categories were identified: cardiac, midline, Beckwith-Weidemann Syndrome, and other genetic anomalies. RESULTS: We identified 105 CAWD patients (UCH n = 40; GO n = 34; and NGO n = 31). Ninety percent of UCH underwent primary repair, 10% were never repaired. NGOs were repaired by primary or staged methods in 92.9% of cases and 7.1% by delayed repair. Primary or staged repair occurred in 32.4% of GOs and delayed repair occurred in 67.6%. The median days to repair was 181 [24,427] GO, 1 [1,3] NGO, and 1 [0,1] UCHs (P < 0.01). Index hospitalization median LOS (days) was 90 [55,157] GO, 23 [10,48] NGO, 9 [5,22] UCH, (P < 0.01). There were no statistical differences in survival rates, number of patients with major anomalies (GO 35.4%, NGO 51.5%, UCH 50%), or types of anomalies. CONCLUSIONS: UCHs and omphaloceles have similar incidences of major associated anomalies. Thus, all patients with a covered abdominal wall defect should undergo workup for associated anomalies.

Surgical Management of Congenital Lung Malformations.

Congenital lung malformations (CLMs) are commonly diagnosed prenatal lesions with varied natural history. Prenatal diagnosis and monitoring help to guide fetal interventions, delivery planning, and need for urgent perinatal surgical interventions. All prenatally diagnosed CLMs should be evaluated postnatally, typically with cross-sectional imaging, because many lesions persist despite the appearance of complete 'regression' in utero. Management of CLMs in asymptomatic infants weighs the surgical and anesthetic risk of prophylactic resection against the risk of expectant management, including the possibility of infection, malignant degeneration, and more complicated surgical resection later with loss of compensatory lung growth.

Minimally Invasive Fetal Surgery and the Next Frontier.

Most patients with congenital anomalies do not require prenatal intervention. Furthermore, many congenital anomalies requiring surgical intervention are treated adequately after birth. However, there is a subset of patients with congenital anomalies who will die before birth, shortly after birth, or experience severe postnatal complications without fetal surgery. Fetal surgery is unique in that an operation is performed on the fetus as well as the pregnant woman who does not receive any direct benefit from the surgery but rather lends herself to risks, such as hemorrhage, abruption, and preterm labor. The maternal risks involved with fetal surgery have limited the extent to which fetal interventions may be performed but have, in turn, led to technical innovations that have significantly advanced the field. This review will examine congenital abnormalities that can be treated with minimally invasive fetal surgery and introduce the next frontier of prenatal management of fetal surgical pathology.

To Err is human, but what happens when surgeons Err?

BACKGROUND: Physicians involved in adverse events may suffer from second victim syndrome and can experience emotional and physical distress long after the complication occurred. We sought determine the prevalence of second victim syndrome among surgeons at our children's hospital and evaluate any differences in how surgeons respond to adverse events based on their age, position, and gender. METHODS: An anonymous 19-question questionnaire distributed via institutional emails linking to an anonymous Research Electronic Data Capture (REDCap) survey. Eligible participants included all surgeons and rotating surgical trainees at our hospital. RESULTS: Of 64 faculty surgeons eligible to participate, 63 surveys were returned for a 98% completion rate. Ten additional surveys from surgical trainees were completed for a total of 73 participants. Eighty-four percent reported having had difficulty dealing with a poor outcome or unhappy patient/family. Speaking with a colleague was the most common coping strategy, reported by 82%. Fifty-six percent indicated they believed reporting a poor outcome would have negative ramifications for them. Younger surgeons were more likely to suppress their feelings following an adverse event, and trainees were less likely to advise their peers to speak to a superior about the event (p < 0.05). CONCLUSION: There is a high prevalence of second victim syndrome among surgeons at our children's hospital. There exist differences in ways that surgeons respond to adverse events based on age and position. Healthcare institutions should establish formal mechanisms of support to shift the culture towards one where help is actively sought and offered. LEVEL OF EVIDENCE: IV.
