Optimal inguinal hernia repair timing remains controversial. It remains unclear how COVID-19 related elective surgery cancellations impacted timing of inguinal hernia repair and whether any delays led to complications. This study aims to determine whether elective surgery cancellations are safe in pediatric inguinal hernia.This multicenter retrospective cohort study at 14 children's hospitals included patients ≤18 years who underwent inguinal hernia repair between September 13, 2019, through September 13, 2020. Patients were categorized by whether their inguinal hernia repair occurred before or after their hospital's COVID-19 elective surgery cancellation date. Incarceration and emergency department encounters were compared between pre and postcancellation.Of 1,404 patients, 604 (43.0%) underwent inguinal hernia repair during the postcancellation period, 92 (6.6%) experienced incarceration, and 213 (15.2%) had an emergency department encounter. The postcancellation period was not associated with incarceration (odds ratio 1.54; 95% confidence interval 0.88-2.71; P = .13) or emergency department encounters (odds ratio 1.53; 95% confidence interval 0.94-2.48; P = .09) despite longer median times to inguinal hernia repair (precancellation 29 days [interquartile range 13-55 days] versus postcancellation 31 days [interquartile range 14-73 days], P = .01). Infants were more likely to have the emergency department be their index presentation in the postcancellation period (odds ratio 1.69; 95% confidence interval 1.24-2.31; P.01).Overall, COVID-19 elective surgery cancellations do not appear to increase the likelihood of incarceration or emergency department encounters despite delays in inguinal hernia repair, suggesting that cancellations are safe in children with inguinal hernia. Assessment of elective surgery cancellation safety has important implications for health policy.

Purpose We aim to assess the healthcare value achieved from a shared savings program for pediatric appendectomy. Methods All appendectomy patients covered by our health plan were included. Quality targets were 15% reduction in time to surgery, length of stay, readmission rate, and patient satisfaction. Quality targets and costs for an appendectomy episode in two 6-month performance periods (PP1, PP2) were compared to baseline. Results 640 patients were included (baseline:317, PP1:167, PP2:156). No quality targets were met in PP1. Two quality targets were met during PP2: readmission rate (−57%) and patient satisfaction. No savings were realized because the cost reduction threshold (−9%) was not met during PP1 (+1.7%) or PP2 (−0.4%). Conclusions Payer-provider partnerships can be a platform for testing value-based reimbursement models. Setting achievable targets, identifying affectable quality metrics, considering case mix index, and allowing sufficient time for interventions to generate cost savings should be considered in future programs.

INTRODUCTION Studies have shown the benefit of intensive care unit (ICU) bundled protocols; however, they are primarily derived from medical patients. We hypothesized that patients and their medication profiles are different between critically ill medical, surgical, and trauma patients. METHODS The Pediatric Health Information System 2017 dataset was used to perform a retrospective cohort study of critically ill children. The pediatric medical, surgical, and trauma cohorts were separated based on ICD-10 codes. Data collected included demographics, secondary diagnoses, outcomes, and medication data. Medications were grouped as opiates, GABA-agonists, alpha-2 agonists, anti-psychotics, paralytics, and "other" sedatives. A non-parametric Kolmogorov-Smirnov test (KS test) and odds ratios (reference group: medical cohort) were calculated to compare medication administration between the study cohorts for the first 30 ICU days. RESULTS A total of 4488 critically ill children (medical 2078, surgical 1650, and trauma 760) were identified. The trauma cohort had increased incidence of delirium (medical 10.8%, surgical 11.5%, trauma 13.8%; p 50% received GABA-agonists on ICU days 0-30. With the KS test, there was a significant difference in administration of opiates, GABA-agonists, alpha-2 agonists, anti-psychotics, and "other" sedatives over the first 30 days in the ICU. Relative to medical patients, trauma patients had significantly higher odds of receiving anti-psychotics on ICU days 10-20 and 22-24. CONCLUSION Critically ill pediatric trauma, medical, and surgical patients are distinctly different patient populations with differing pharmacologic profiles for analgesia, sedation, and delirium.

SARS-CoV-2 has profoundly affected the way healthcare is delivered and has created significant strain on medical facilities globally. As a result, hospitals have had to continuously adapt in order to provide optimal patient care while minimizing the risk of SARS-CoV-2 transmission, particularly in the surgical setting. Texas Children's Hospital developed a set of protocols for surgical screening and clearance of patients in the context of the COVID-19 pandemic. These screening protocols were designed to mitigate the risk of exposing patients and healthcare providers to SARS-CoV-2 and have evolved significantly as a result of the emerging changes in medicine, technology, and governmental regulations. In this article, we share the reasoning behind the development, implementation, and successive modification of our institutional screening protocols.

This cohort study examines resident involvement in the care of US veterans who underwent noncardiac surgery.

Sirolimus has demonstrated effectiveness as a treatment option for several types of vascular anomalies; however, it has a potential side effect of delayed surgical wound healing. The purpose of this study was to evaluate the association of sirolimus with postoperative complications in the pediatric vascular anomaly population.A retrospective cohort study was performed for children with a vascular anomaly who underwent excision or debulking of the anomaly from 2015 to 2020. Patient demographics, vascular anomaly characteristics, operative variables, sirolimus dosing information, and perioperative outcomes were collected. Univariate analysis was performed to compare outcomes based on the administration of sirolimus.Forty-seven patients with vascular anomalies underwent 57 surgical procedures (36 without perioperative sirolimus, 21 with perioperative sirolimus). The median age at the time of surgery was seven years (IQR 1.7-14.0). The most common anomalies were lymphatic and venolymphatic malformations. Of the patients administered perioperative sirolimus, the median preoperative and postoperative sirolimus levels were comparable (preoperative 6.9 ng/mL (IQR 4.9-10.1), postoperative 6.5 ng/mL (IQR 4.7-9.4)). The rate of postoperative complications (sirolimus 19%, without sirolimus 11%; p = 0.45) and wound complications (sirolimus 14%, without sirolimus 6%; p = 0.26) were comparable between the cohorts.Our results suggest sirolimus may not significantly increase perioperative complication rates in pediatric patients undergoing resection of their vascular anomaly.Level III.

To determine the association between risk adjusted hospital perioperative mortality rates, postoperative complications, and failure to rescue (FTR) after inpatient pediatric surgery.FTR has been identified as a possible explanatory factor for hospital variation in perioperative mortality in adults. However, the extent to which this may be the case for hospitals that perform pediatric surgery is unclear.The Pediatric Health Information System® database (2012-2020) was used to identify patients who underwent one of 57 high-risk operations associated with significant perioperative mortality (n=203,242). Academic, pediatric hospitals (n=48) were stratified into quintiles based on risk adjusted inpatient mortality (lower than average, quintile 1 [Q1]; higher than average, quintile 5 [Q5]). Multivariable hierarchical regression was used to evaluate the association between hospital mortality rates, complications, and FTR.Inpatient mortality, complication, and FTR rates were 2.3%, 8.8%, and 8.8%, respectively. Among all patients who died after surgery, only 34.1% had a preceding complication (Q1, 36.1%; Q2, 31.5%; Q3, 34.7%; Q4, 35.7%; Q5, 32.2%; trend test, P=0.49). The rates of observed mortality significantly increased across hospital quintiles, but the difference was1% (Q1, 1.9%; Q5; 2.6%; trend test, P0.01). Relative to Q1 hospitals, the odds of complications were not significantly increased at Q5 hospitals (OR 1.02 [0.87-1.20]). By comparison, the odds of FTR was significantly increased at Q5 hospitals (OR 1.60 [1.30-1.96]) with a dose-response relationship across hospital quintiles (Q2-OR 0.99 [0.80-1.22]; Q3-OR 1.26 [1.03-1.55]; Q4-OR 1.33 [1.09-1.63]).The minority of pediatric surgical deaths are preceded by a postoperative complication, but variation in risk adjusted mortality across academic, pediatric hospitals may be partially explained by differences in the recognition and management of postoperative complications. Additional work is needed to identify children at greatest risk of postoperative death from perioperative complications as opposed to those at risk from pre-existing chronic conditions.

Introduction The Nuss procedure is the most common and preferred operative correction of pectus excavatum. Surgeon preference and patient factors can result in variations in Nuss procedure technique. We hypothesize that certain techniques are associated with increased risk of complications. Materials and Methods We performed a single-center retrospective review of Nuss operations from 2016 to 2020. Variations in intraoperative techniques included sternal elevator (SE) use, number of bars placed, and usage of bilateral stabilizing sutures. Patient demographics, intraoperative data, and postoperative outcomes were reported as median with interquartile ranges or percentages. Statistical significance (p Results Two hundred and sixty-five patients were identified. Patients repaired with two bars were older with a larger Haller index (HI). Patient demographics were not significantly different for SE or stabilizing suture use. Placement of two bars was associated with significantly increased risk of readmission. Similarly, SE use was associated with increased risk of pleural effusion and readmission. Finally, the use of bilateral stabilizing sutures resulted in less frequent slipped bars without statistical significance. Conclusion Older patients with a larger HI were more likely to need two bars placed to repair pectus excavatum. Placement of multiple bars and SE use are associated with significantly higher odds of certain complications.

Children undergoing open oncologic surgery can have significant post-operative pain. The purpose of this trial was to compare a surgeon-placed subcutaneous analgesic system (SAS) to epidural analgesia.Single center randomized controlled trial including children ≤18 years undergoing open tumor resection between October 2018 and April 2021. Randomization to SAS or epidural was done preoperatively and perioperative pain management was standardized. Families were blinded to the modality. Comparisons of oral morphine equivalents (OME) and pain scores for three postoperative days, clinical outcome parameters, and parental satisfaction following unblinding were completed using non-parametric analyses.Of 36 patients (SAS 18, Epidural 18), median age was 5 years (range1-17). The Epidural cohort had less OME demand on postoperative day one (SAS 0.76 mg/kg, Epidural 0.11 mg/kg; p0.01) and two (SAS 0.48 mg/kg, Epidural 0.07 mg/kg, p = 0.03). Pain scores were similar on postoperative days 1-3 (0-2 in both groups). The Epidural cohort had more device complications (SAS 11%, Epidural 50%; p = 0.03) and higher urinary catheter use (SAS 50%, Epidural 89%; p = 0.03). More than 80% of parents would use the same device in the future (SAS 100%, Epidural 84%, p = 0.23).For children undergoing open oncologic abdominal or thoracic surgery, early post-operative pain control appears to be better with epidural analgesia; however, SAS has decreased incidence of device complications and urinary catheter use. Parental satisfaction is excellent with both modalities. SAS could be considered as an alternative to epidural, especially in settings when epidural placement is not available or contraindicated.Treatment study, Randomized controlled trial.Level 1.

This is the case of a pediatric blunt trauma patient who presented with a concurrent blunt traumatic aortic and severe brain injury. We describe successful simultaneous management of the aortic and brain injury with delayed endovascular repair of the aorta. This report details the importance of multidisciplinary discussion in definitive management of children with these concurrent injuries and the endovascular technical considerations in children.

Investigate patterns of infant perioperative mortality, describe the infant diagnoses with the highest mortality burden, and evaluate the association between types of postoperative complications and mortality in infants.The majority of mortality events in pediatric surgery occur among infants (i.e. children1 y old). However, there is limited data characterizing patterns of infant perioperative mortality and diagnoses that account for the highest proportion of mortality.Infants who received inpatient surgery were identified in the National Surgical Quality Improvement Program-Pediatric database (2012-2019). Perioperative mortality was stratified into mortality associated with a complication or mortality without a complication. Complications were categorized as wound infection, systemic infection, pulmonary, central nervous system (CNS), renal, or cardiovascular. Multivariable logistic regression was used to evaluate the association between different complications and complicated mortality.Among 111,946 infants, the rate of complications and perioperative mortality was 10.4% and 1.6%, respectively. Mortality associated with a complication accounted for 38.8% of all perioperative mortality. Seven diagnoses accounted for the highest proportion of mortality events (40.3%): necrotizing enterocolitis (22.3%); congenital diaphragmatic hernia (7.3%); meconium peritonitis (3.8%); premature intestinal perforation (2.5%); tracheoesophageal fistula (1.8%); gastroschisis (1.4%); and volvulus (1.1%). Relative to wound complications, cardiovascular (Odds Ratio [OR] 19.4, 95% CI [13.9-27.0]), renal (OR 6.88 [4.65-10.2]), and CNS complications (OR 6.50 [4.50-9.40]) had the highest odds of mortality for all infants.A small subset of diagnoses account for 40% of all infant mortality and specific types of complications are associated with mortality. These data suggest targeted quality improvement initiatives could be implemented to reduce adverse surgical outcomes in infants.

No consensus guidelines exist for timing of enterostomy closure in neonatal isolated intestinal perforation (IIP). This study evaluated neonates with IIP closed during the initial admission (A1) versus a separate admission (A2) comparing total length of stay and total hospital cost.Using 2012 to 2017 Pediatric Health information System (PHIS) data, 359 neonates with IIP were identified who underwent enterostomy creation and enterostomy closure. Two hundred sixty-five neonates (A1) underwent enterostomy creation and enterostomy closure during the same admission. Ninety-four neonates (A2) underwent enterostomy creation at initial admission and enterostomy closure during subsequent admission. For the A2 neonates, total hospital length of stay was calculated as the sum of hospital days for both admissions. A1 neonates were matched to A2 neonates in a 1:1 ratio using propensity score matching. Multivariate models were used to compare the two matched pair groups for length of stay and cost comparisons.Prior to matching, the basic demographics of our study population included a median birthweight of 960 g, mean gestational age of 29.5 weeks, and average age at admission of 4 days. Eighty-seven pairs of neonates with IIP were identified during the matching process. Neonates in A2 had 91% shorter total hospital length of stay compared to A1 neonates (HR: 1.91; 95% CI for HR: 1.44-2.53; p .0001). The median length of stay for A1 was 95 days (95% CI: 78-102 days) versus A2 length of stay of 67 days (95% CI: 56-76 days). Adjusting for the same covariates, A2 neonates had a 22% reduction in the average total cost compared A1 neonates (RR: 0.78; 95% CI for RR: 0.64-0.95; p-value = 0.014). The average total costs were $245,742.28 for A2 neonates vs. $315,052.21 for A1 neonates (p 0.001).Neonates with IIP have a 28 day shorter hospital length of stay, $75,000 or 24% lower total hospital costs, and a 22 day shorter post-operative course following enterostomy closure when enterostomy creation and closure is performed on separate admissions.Prognosis Study.Level II.

IntroductionData examining rates of postoperative complications among SARS-CoV-2 positive children are limited. The purpose of this study was to evaluate the impact of symptomatic and asymptomatic SARS-CoV-2 positive status on postoperative respiratory outcomes for children.MethodsThis retrospective cohort study included SARS-CoV-2 positive pediatric patients across 20 hospitals who underwent general anesthesia from March to October 2020. The primary outcome was frequency of postoperative respiratory complications, including: high-flow nasal cannula/non invasive ventilation, reintubation, pneumonia, Extracorporeal Membrane Oxygenation (ECMO), and 30-day respiratory-related readmissions or emergency department (ED) visits. Univariate analyses were used to evaluate associations between patient and procedure characteristics and stratified analyses by symptoms were performed examining incidence of complications.ResultsOf 266 SARS-CoV-2 positive patients, 163 (61.7%) were male, and the median age was 10 years (interquartile range 4-14). The majority of procedures were emergent or urgent (n=214, 80.5%). The most common procedures were appendectomies (n=78, 29.3%) and fracture repairs (n=40,15.0%). 13 patients (4.9%) had preoperative symptoms including cough or dyspnea. 26 patients (9.8%) had postoperative respiratory complications, including 15 requiring high-flow oxygen, 8 with pneumonia, 4 requiring non invasive ventilation, 3 respiratory ED visits, and 2 respiratory readmissions. Respiratory complications were more common among symptomatic patients than asymptomatic patients (30.8% vs. 8.7%, p=0.01). Higher ASA class and comorbidities were also associated with postoperative respiratory complications.ConclusionsPostoperative respiratory complications are less common in asymptomatic versus symptomatic SARS-COV-2 positive children. Relaxation of COVID-19-related restrictions for time-sensitive, non urgent procedures in selected asymptomatic patients may be reasonably considered. Additionally, further research is needed to evaluate the costs and benefits of routine testing for asymptomatic patients.Level of evidenceIii, Respiratory complications.

The COVID-19 pandemic has impacted timely access to care for children, including patients with appendicitis. This study aimed to evaluate the effect of the COVID-19 pandemic on management of appendicitis and patient outcomes.A multicenter retrospective study was performed including 19 children's hospitals from April 2019-October 2020 of children (age≤18 years) diagnosed with appendicitis. Groups were defined by each hospital's city/state stay-at-home orders (SAHO), designating patients as Pre-COVID (Pre-SAHO) or COVID (Post-SAHO). Demographic, treatment, and outcome data were obtained, and univariate and multivariable analysis was performed.Of 6,014 patients, 2,413 (40.1%) presented during the COVID-19 pandemic. More patients were managed non-operatively during the COVID-19 pandemic compared to before the pandemic (147 (6.1%) vs 144 (4.0%), p0.001). Despite this change, there was no difference in the proportion of complicated appendicitis between groups (1,247 (34.6%) vs 849 (35.2%), p = 0.12). COVID era non-operative patients received fewer additional procedures, including interventional radiology (IR) drain placements, compared to pre-COVID non-operative patients (29 (19.7%) vs 69 (47.9%), p0.001). On adjusted analysis, factors associated with increased odds of receiving non-operative management included: increasing duration of symptoms (OR=1.01, 95% CI: 1.01-1.012), African American race (OR=2.4, 95% CI: 1.3-4.6), and testing positive for COVID-19 (OR=10.8, 95% CI: 5.4-21.6).Non-operative management of appendicitis increased during the COVID-19 pandemic. Additionally, fewer COVID era cases required IR procedures. These changes in the management of pediatric appendicitis during the COVID pandemic demonstrates the potential for future utilization of non-operative management.

Although case reports have suggested an association between severe acute respiratory distress syndrome coronavirus 2 and appendicitis, we found that the overall incidence of appendicitis was stable throughout the pandemic at our tertiary pediatric hospital. Furthermore, we did not find evidence of CoV2 infection in 9 appendicitis tissues. Therefore, we conclude that severe acute respiratory distress syndrome coronavirus 2 infection of the appendix is not a common etiologic cause of pediatric appendicitis.

IntroductionThe National Institutes of Health (NIH) provides research funding to scientists at different stages of their career through a range of grant awards. Early-stage researchers are eligible for mentored Career Development (K) awards, to aid in the transition to independent NIH funding. Factors such as education, subspecialty, and time to funding have been studied as predictors of obtaining independent awards in nonsurgical specialties. However, in surgery, the importance of these factors has yet to be clearly elucidated. We aim to identify predictors of K to independent award conversion among surgeon-scientists to understand how to better support early-stage researchers transitioning to independent careers.Materials and MethodsIn July 2020, the NIH Research Portfolio Online Reporting Tools database was queried for individuals affiliated with surgery departments who received NIH Career Development Awards (between 2000 and 2020). The following factors were analyzed: publications, institution, degrees, year of completion of training, and gender.ResultsBetween 2000 and 2020, 228 surgeons received K Awards, of which 44% transitioned to independent funding. On average, surgeons received a K award 4.0 years after completing fellowship training and an independent award 5.4 years after receiving a K grant. The time to receiving a K award was predictive of successfully achieving independent funding, and those with independent funding had a significantly greater number of publications per year of their K-award.ConclusionSurgeons successful in transitioning to independent NIH awards do so approximately 9 years after finishing fellowship. Publication track record is the main factor associated with successful conversion from a K award. Surgery departments should emphasize manuscript productivity and develop strategies to minimize time to independent funding to help K-awardees begin independent research careers.

Congenital diaphragmatic hernia is associated with pulmonary hypoplasia, pulmonary hypertension, and significant neonatal morbidity. Although intrathoracic liver herniation (LH)20% is associated with adverse outcomes, the relationship between LH20% and outcomes is poorly characterized.A single-center retrospective cohort study was performed from 2011 to 2020 of 80 fetuses with left-sided congenital diaphragmatic hernia that were delivered and repaired at our institution. Perinatal, perioperative, and postoperative data were collected. We evaluated the association of %LH with outcomes as a stratified ordinal variable (0%-10% LH, 10%-19% LH, and20% LH) and as a continuous variable. Data were analyzed by analysis of variance with Bonferroni post hoc analysis, chi-square analyses, and univariate logistic regression.Extracorporeal membrane oxygenation (ECMO) (P 0.001), repair on ECMO (P = 0.002), repair with patch (P 0.001), length of stay (P = 0.002), inhaled nitric oxide use (P 0.001), and sildenafil use at discharge (P 0.001), showed significant differences among LH groups. There were no differences among the groups concerning survival (at discharge, 6 mo, and 1 y) and tracheostomy. On further analysis there was no difference between 10% and 19% LH and ≥20% LH patients concerning ECMO (P = 0.55), repair on ECMO (P = 0.54), repair with patch (P = 1.00), length of stay (P = 1.00), and inhaled nitric oxide use (P = 0.33). Logistic regression analysis displayed a significant association with LH and ECMO, repair on ECMO, repair with patch, inhaled nitric oxide use, and sildenafil use.Our analysis displays no significant difference in perinatal management between patients with 10%-19% and ≥20% LH. These findings suggest that the historical cutoff of ≥20% LH may not be sufficient alone to guide perinatal counseling and decision-making.

COVID-19 spurred an unprecedented transition from in-person to telemedicine visits in March 2020 at our institution for all prenatal counseling sessions. This study aims to explore differences in demographics of expectant mothers evaluated pre- and post-telemedicine implementation and to explore the patient experience with telemedicine.A mixed methods study was completed for mothers with a pregnancy complicated by a fetal surgical anomaly who visited a large tertiary fetal center. Using medical records as quantitative data, patient information was collected for all prenatal visits from 3/2019 to 3/2021. The sample was grouped into pre- and post-telemedicine implementation (based on transition date of 3/2020). Univariate analysis was used to compare demographics between the study groups. Statistical significance was defined as P 0.05. Eighteen semi-structured interviews were conducted from 8/2021 to 12/2021 to explore patients' experiences. Line-by-line coding and thematic analysis was performed to develop emerging themes.292 pregnancies were evaluated from 3/2019 to 3/2021 (pre-telemedicine 123, post-telemedicine 169). There was no significant difference in self-reported race (P = 0.28), ethnicity (P = 0.46), or primary language (P = 0.98). In qualitative interviews, patients reported advantages to telemedicine, including the convenience of the modality with the option to conduct their session in familiar settings (e.g., home) and avoid stressors (e.g., travel to the medical center and finding childcare). Some women reported difficulties establishing a physician-patient connection and a preference for in-person consultations.There was no difference in patient demographics at our fetal center in the year leading up to, and the time following, a significant transition to telemedicine. However, patients had unique perspectives on the advantages and disadvantages of the telemedicine experience. To ensure patient centered care, these findings suggest patient preference should be considered when scheduling outpatient surgical counseling and visits.

The purpose of the present study is to evaluate our institutional management of high-risk congenital lung malformations (CLM) with particular consideration of the use of multiple maternal steroid courses and maternal steroids in CLMs with pathologies other than congenital pulmonary airway malformation (CPAM).A single-center retrospective review was performed for all fetuses evaluated for CLM who received maternal steroids and/or had a CLM volume ratio (CVR) ≥ 1.6 (2015-2020). Fetuses were categorized as receiving no steroids, single steroid, or multiple steroid courses. Outcomes evaluated included CVR growth rate, resolution of early hydrops, and resolution of hydrops. Results are reported with a descriptive analysis.Nineteen patients were identified who had CVR ≥ 1.6 (single steroid course 9/19, multiple steroid courses 6/19, and no steroids 4/19). A majority (n = 13, 68%) of all lesions had a reduction or no change in CVR between initial and final measurements (single steroid course 7/9, 78%; multiple steroid courses 4/6, 67%). When evaluating by pathology, ≥ 50% of each classification had reduction or no growth of CVR (CPAM 7/11, bronchial atresia 2/4, sequestration 3/3, congenital lobar emphysema 1/1). Seventy five percent (3/4) of lesions with early hydrops had resolution following steroid treatment (single steroid course 1, multiple steroid courses 2). Of the four lesions that had hydrops, only one had resolution after receiving multiple steroid courses.Our institutional experience reports the majority of CLM (including pathologies other than CPAM) who received steroids had reduction or no change in CVR. Given the low risk-benefit ratio of maternal steroids, physicians could consider use of multiple steroid courses for CLM refractory to a single course.

Abdominal lymphatic malformations (LM) have been historically managed with surgical resection; however, sclerotherapy and sirolimus have emerged as effective therapies. The purpose of our study is to evaluate our institutional change in management and outcomes for abdominal LM over the past decade.A retrospective cohort study was performed for all children with an abdominal LM managed at our multidisciplinary Vascular Anomalies Center from 2011 to 2020. Patient demographics, symptoms, treatment, treatment response, and complications were analyzed with descriptive statistics.Twenty-nine patients with abdominal LM were identified with a median age at treatment of 6 y (interquartile range 3-14). A majority of lesions were identified as macrocystic (n = 18, 62%). The most common intervention was surgery alone (n = 14, 48%) followed by sirolimus alone (n = 4, 14%), and sclerotherapy + sirolimus (n = 4, 14%). Five patients were observed due to lack of symptoms at presentation. Prior to 2017, 91% (10/11) of LM were treated with surgery alone. Following 2017, only 31% (4/13) were treated with surgery alone. Sixty-seven percent (16/24) of treated patients had95% reduction in LM maximum diameter. A majority of patients (23/24) who received treatment had improvement or resolution of symptoms at median 9-mo follow-up. Only three patients had post-treatment complications, including a drain site infection, small bowel obstruction, and an aspiration event. Complications only occurred after sclerotherapy sessions.Over the study period, our institution has transitioned to initial management of symptomatic abdominal LM with sclerotherapy and/or sirolimus with almost all treated patients having excellent or satisfactory treatment response. Post-treatment complications were rare.

Intercostal nerve cryoablation with the Nuss procedure has been shown to decrease opioid requirements and hospital length of stay; however, few studies have evaluated the impact on complications and hospital costs.A retrospective cohort study was performed for all Nuss procedures at our institution from 2016 through 2020. Outcomes were compared across 4 pain modalities: cryoablation with standardized pain regimen (n = 98), patient-controlled analgesia (PCA; n = 96), epidural (n = 36), and PCA with peripheral nerve block (PNB; n = 35). Outcomes collected included length of stay, opioid use, variable direct costs, and postoperative complications. Univariate and multivariate hierarchical regression analysis was used to compare outcomes between the pain modalities.Cryoablation was associated with increased total hospital cost compared with PCA (cryoablation, $11 145; PCA, $8975; P.01), but not when compared with epidural ($9678) or PCA with PNB ($10 303). The primary driver for increased costs was operating room supplies (PCA, $2741; epidural, $2767; PCA with PNB, $3157; and cryoablation, $5938; P.01). With multivariate analysis, cryoablation was associated with decreased length of stay (-1.94; 95% CI, -2.30 to -1.57), opioid use during hospitalization (-3.54; 95% CI, -4.81 to -2.28), and urinary retention (0.13; 95% CI, 0.05-0.35).Cryoablation significantly reduces opioid requirements and length of stay relative to alternative modalities, but it was associated with an increase in total hospital costs relative to PCA, but not epidural or PCA with PNB. Cryoablation was not associated with allodynia or slipped bars requiring reoperation.

INTRODUCTION: Red blood cell transfusion (RBCT) is commonly administered in neonatal surgical care in the absence of clear clinical indications such as active bleeding or anemia. We hypothesized that higher RBCT volumes are associated with worse postoperative outcomes. METHODS: Neonates within the National Surgical Quality Improvement Program–Pediatric database who underwent inpatient surgery (2012–2016) were stratified by weight-based RBCT volume: < 20 cc/kg, 20–40 cc/kg, and > 40 cc/kg. Postoperative complications were categorized as wound, systemic infection, central nervous system (CNS), renal, pulmonary, and cardiovascular. Multivariable logistic regression and cubic spline analysis were used to evaluate the association between RBCT volume, postoperative complications, and 30–day mortality. Sensitivity analysis was conducted by performing propensity score matching. RESULTS: Among 9,877 neonates, 1,024 (10%) received RBCTs. Of those who received RBCT, 53% received < 20 cc/kg, 27% received 20–40 cc/kg, and 20% received > 40 cc/kg. Relative to neonates who were not transfused, RBCT volume was associated with a dose-dependent increase in renal complications, CNS complications, cardiovascular complications, and 30-day mortality. With cubic spline analysis, a lone inflection point for 30-day mortality was identified at a RBCT volume of 30 – 35 cc/kg. After propensity score matching, the dose-dependent relationship was still present for 30-day mortality. CONCLUSION: Total RBCT volume is associated with worse postoperative outcomes in neonates with a significant increase in 30-day mortality at a RBCT volume of 30 – 35cc/kg. Future prospective studies are needed to better understand the association between large RBCT volumes and poor outcomes after neonatal surgery.

BACKGROUND: Pediatric trauma patients sustaining blunt abdominal trauma (BAT) with intra-abdominal injury (IAI) are frequently admitted to the intensive care unit (ICU). This study was performed to identify predictors for ICU admission following BAT. METHODS: Prospective study of children (< 16 years) who presented to 14 Level-One Pediatric Trauma Centers following BAT over a 1-year period. Patients were categorized as ICU or non-ICU patients. Data collected included vitals, physical exam findings, laboratory results, imaging, and traumatic injuries. A multivariable hierarchical logistic regression model was used to identify predictors of ICU admission. Predictive ability of the model was assessed via tenfold cross-validated area under the receiver operating characteristic curves (cvAUC). RESULTS: Included were 2,182 children with 21% (n = 463) admitted to the ICU. On univariate analysis, ICU patients were associated with abnormal age-adjusted shock index, increased injury severity scores (ISS), lower Glasgow coma scores (GCS), traumatic brain injury (TBI), and severe solid organ injury (SOI). With multivariable logistic regression, factors associated with ICU admission were severe trauma (ISS > 15), anemia (hematocrit < 30), severe TBI (GCS < 8), cervical spine injury, skull fracture, and severe solid organ injury. The cvAUC for the multivariable model was 0.91 (95% CI 0.88–0.92). CONCLUSION: Severe solid organ injury and traumatic brain injury, in association with multisystem trauma, appear to drive ICU admission in pediatric patients with BAT. These results may inform the design of a trauma bay prediction rule to assist in optimizing ICU resource utilization after BAT. STUDY DESIGN: Prognosis study. LEVEL OF EVIDENCE: 1.

The purpose of this study is to evaluate the relationship of social continence with patient centered outcomes, such as quality of life, in children with sarococcygeal teratoma (SCT). We hypothesize there is a correlation between social continence and patient-centered outcomes.A chart review and three surveys (Pediatric Quality of Life Inventory™ (PedsQL™), Baylor Continence Scale (BCS), and Impact on Family (IOF)) were performed for SCT patients who underwent resection at our institution from 2013 to 2018. PedsQL™ assesses quality of life, BCS evaluates global continence, and the IOF scale measures the impact of a child's illness on the family. Pearson correlation was used to examine the relationship between BCS, PedsQL™, and IOF.Eighteen patients were identified with 72% (13/18) participating in the surveys with a median age at time of survey of 4.7 years (range 2.8-7.9). Patients with Altman IV were diagnosed postnatally and had smaller tumors. At the time of survey administration, a majority of children were toilet trained (54%, 7/13). Parents reported urinary incontinence (46%, 6/13) more frequently than bowel incontinence (15%, 2/13). Altman III/IV trended towards worse PedsQL™, BCS, and IOF surveys; however, it was not significant. The BCS correlated with the Total PedsQL™ (ρ = -0.56, p = 0.048) and IOF (ρ = 0.68, p = 0.011).Children with SCT have a correlation between social continence, quality of life, and the impact on family. This study suggests interventions to screen and improve continence in children with SCT could also improve patient centered metrics.Cross-sectional study LEVEL OF EVIDENCE: Level II, Prognosis Study.

Congenital lung malformation (CLM) volume ratio (CVR) of ≥1.1 has been shown to be highly predictive of the need for urgent, perinatal surgical intervention. The purpose of this study was to utilize this information to propose a delivery planning and clinical management algorithm based on this threshold.A retrospective cohort study was performed for all fetuses evaluated at our fetal center between 5/2015 and 11/2020. Demographics, ultrasound findings, late gestation CVR (≥27 weeks gestational age), prenatal and postnatal treatment, and outcomes were analyzed with nonparametric univariate analysis based on late gestation CVR of 1.1. Receiver operating characteristic curve analysis was performed to evaluate association between late gestation CVR, hydrops, need for fetal intervention, and need for urgent perinatal surgery.Of the 90 CLMs referred to our fetal center, 65 had late gestation CVR with a majority1.1 (47/65, 72%). All patients with late gestation CVR ≥ 1.1 were managed with resection (18/18) with most resections requiring fetal intervention or urgent neonatal resection (13/18). Late gestation CVR 1.1 were managed with elective resection (36/47, 77%) or non-operative observation (11/47, 23%). Late gestation CVR ≥ 1.1 had 100% sensitivity and NPV for hydrops, need for fetal intervention, and need for urgent perinatal surgery.CLM with CVR ≥ 1.1 were associated with urgent perinatal surgical intervention and expectant mothers should plan for delivery at centers equipped to manage neonatal resuscitation and potential urgent neonatal resection. Conversely, CLM with CVR 1.1 may be safe to deliver at patient hospital of choice.

Background: Thoracic inlet (TI) tumors are rare, and can be particularly challenging to resect due to proximity to mediastinal vessels and nerves. Traditional resection is typically performed throu...

Studies have shown the benefit of intensive care unit (ICU) bundled protocols; however, they are primarily derived from medical patients. We hypothesized that patients and their medication profiles are different between critically ill medical, surgical, and trauma patients.The Pediatric Health Information System 2017 dataset was used to perform a retrospective cohort study of critically ill children. The pediatric medical, surgical, and trauma cohorts were separated based on ICD-10 codes. Data collected included demographics, secondary diagnoses, outcomes, and medication data. Medications were grouped as opiates, GABA-agonists, alpha-2 agonists, anti-psychotics, paralytics, and "other" sedatives. A non-parametric Kolmogorov-Smirnov test (KS test) and odds ratios (reference group: medical cohort) were calculated to compare medication administration between the study cohorts for the first 30 ICU days.A total of 4488 critically ill children (medical 2078, surgical 1650, and trauma 760) were identified. The trauma cohort had increased incidence of delirium (medical 10.8%, surgical 11.5%, trauma 13.8%; p 0.01) and mortality (medical 5.4%, surgical 2.4%, trauma 11.7%; p 0.01). For all study cohorts, 50% received GABA-agonists on ICU days 0-30. With the KS test, there was a significant difference in administration of opiates, GABA-agonists, alpha-2 agonists, anti-psychotics, and "other" sedatives over the first 30 days in the ICU. Relative to medical patients, trauma patients had significantly higher odds of receiving anti-psychotics on ICU days 10-20 and 22-24.Critically ill pediatric trauma, medical, and surgical patients are distinctly different patient populations with differing pharmacologic profiles for analgesia, sedation, and delirium.Level III (Retrospective Comparative Study).

Extrarenal malignant rhabdoid tumors (MRT) are highly aggressive tumors of childhood with a poor overall prognosis. While most commonly found within the kidney and central nervous system, MRT can also occur in other locations and present highly specific challenges for pediatric surgical providers in an effort to achieve a meaningful resection. Cervical rhabdoid tumors are extremely rare. We report the multidisciplinary management of a patient with a complex cervicothoracic malignant rhabdoid tumor who underwent successful surgical resection with a greater than one year survival.

A cascade of complications is believed to be the primary mechanism underlying failure to rescue (FTR), or death of a patient after a postoperative complication. It is unknown whether specific types of index complications are associated with the incidence of secondary complications and FTR after pediatric surgery.National cohort study of patients within the National Surgical Quality Improvement Program-Pediatric database who underwent inpatient surgery (2012-2019). Index complications were grouped into nine categories (cardiovascular, venous thromboembolism, pulmonary, bleeding/transfusion, renal, central nervous system, wound, infectious, or minor [defined as having an associated mortality rate1%]). The association between the type of index complication with FTR, secondary complications, reoperation, unplanned readmission, and postoperative length of stay was evaluated with multivariable logistic regression and generalized linear modeling.Among 425,386 patients, 15.5% had at least one complication, 16.6% had one or more secondary complications, 13.9% reoperation, 14.5% readmission, and 2.4% FTR. Secondary complication (10.8-59.7%) and FTR (0.3-31.1%) rates varied by type of index complication. Relative to patients who had an index minor complication, those with an index infectious complication were most likely to have secondary complication (Odds Ratio [OR] 10.3, 95% CI [9.36-11.4]). Index CV complications were most strongly associated with FTR (OR 30.7 [24.0-39.4]). Index wound complications had the greatest association with reoperation (OR 21.9 [20.5-23.4]) and readmission (OR 18.7 [17.6-19.9]). Index pulmonary complications had the strongest association with length of stay (coefficient 9.39 [8.95-9.83]).Different types of index complications are associated with different perioperative outcomes. These data can help identify patients potentially at risk for suboptimal outcomes and can inform pediatric quality improvement interventions.Cohort study.Level II.

Purpose Ganglioneuroma (GN) and ganglioneuroblastoma-intermixed (GNB-I) represent benign variants of neuroblastic tumors in children; however, differentiating from more aggressive histological variants of GNB including the nodular subtype (GNB-N) prior to resection can be challenging, even with biopsy. Currently, no standard treatment guidelines exist. The purpose of this study was to identify pre-operative characteristics of benign neuroblastic tumors and evaluate outcomes for patients who underwent surgical resection or observation. Methods Retrospective chart review of children treated at a single institution between 2009 and 2019 for non-metastatic tumor with a tissue diagnosis of GN, GNB-N or GNB-I. Demographics, imaging, labs, operative details and outcomes were recorded and analyzed. Results Of 53 patients, 45% were male. The most common tumor location was abdomen (49%), followed by thorax (34%). Forty-five percent had at least one image defined risk factor. Biopsy was performed in 32% (17/53) and upfront surgery in 68% (36/53). Three patients (3/53, 5.6%) with biopsy demonstrating GN tumors were observed due to high surgical risk. Pathology of resected specimens demonstrated GN in 52% (26/50) and GNB-I or GNB-N in 48% (24/50). The majority of GNB tumors (75% (18/24) were GNB-I and 25% (6/24) were GNB-N. Therefore, 88% of the resected tumors were benign spectrum neuroblastic tumors (GN & GNB-I). Seven (7/50, 14%) patients experienced perioperative complication (temporary paralysis, Horner's syndrome, chylothorax, vocal cord paralysis). Recurrence was noted in 1 patient with GN (1/50, 2%) and 3 with GNB-N (3/50, 6%). There were no tumor-related deaths. Patients with GN were older than those with GNB (8.8 years (IQR 6–11.25) vs 5.6 years for GN (IQR 3–7); p = 0.01). GNB tumors were also more likely to have calcifications on imaging (63% vs. 38%, p = .01) and more commonly had MIBG avidity (88% vs 66%, p = .04). There were no significant differences in tumor size or symptoms at presentation. Conclusions In children with neuroblastic tumors, older age, CT without tumor calcifications, lack of MIBG avidity, and/or normal urine catecholamines may indicate benign GN. Close observation could be considered for asymptomatic patients meeting these criteria with biopsy-proven GN, with resection reserved for progressive growth or symptom development. However, larger, multicenter studies are needed for further validation. Level of evidence IV.

Background Recent studies have shown intercostal cryoablation(IC) during the Nuss procedure decreases hospital length of stay(LOS) and opioid administration. However, few studies have also evaluated the risk of postoperative complications related to IC. Methods We performed a single center retrospective analysis of all patients who underwent Nuss procedure by one surgeon from 2/2016 to 2/2020, comparing intraoperative IC to other pain management modalities(non-IC). Primary outcomes were postoperative complications, hospital LOS, and opioid administration. Multivariate analysis was performed with outcomes reported as regression coefficients(RC) or odds ratios(OR) with 95% confidence interval. Results IC was associated with decreased hospital LOS (RC −1.91[−2.29 to −1.54], less hospital opioid administration (RC −4.28[−5.13 to −3.43]), and less discharge opioid administration (RC −3.82[−5.23 to −2.41]). With respect to postoperative complications, IC decreased the odds of urinary retention (OR 0.16[0.06 to 0.44]); however, increased the odds of slipped bars requiring reoperation (OR 36.65[5.04–266.39]). Conclusions Our single surgeon experience controls for surgeon variability and demonstrates intraoperative IC for the Nuss procedure is an effective pain management modality that decreases hospital LOS and opioid use during hospitalization and at discharge; however, it is associated with increased odds of slipped bars requiring reoperation.

Background Current literature has shown that adult patients with perioperative Coronavirus Disease-2019 (COVID-19) have increased rates of postoperative morbidity and mortality. We hypothesized that children with COVID-19 have favorable postoperative outcomes compared to the reported adult experience. Methods We performed a retrospective cohort study for children with a confirmed preoperative COVID-19 diagnosis from April 1st, 2020 to August 15th, 2020 at a free-standing children's hospital. Primary outcomes evaluated were postoperative complications, readmissions, reoperations, and mortality within 30 days of operation. Secondary outcomes included hospital resource utilization, hospital length of stay, and postoperative oxygen support. Results A total of 66 children with preoperative confirmed COVID-19 were evaluated with median age of 9.5 years (interquartile range (IQR) 5–14) with 65% male and 70% Hispanic White. Sixty-five percent of patients had no comorbidities, with abdominal pain identified as the most common preoperative symptom (65%). Twenty-three percent of patients presented with no COVID-19 related symptoms. Eighty-two percent of patients had no preoperative chest imaging and 98% of patients did not receive preoperative oxygen support. General pediatric surgeons performed the majority of procedures (68%) with the most common diagnosis appendicitis (47%). Forty-one percent of patients were discharged the same day as surgery with 9% of patients utilizing postoperative intensive care unit resources and only 5% receiving postoperative invasive mechanical ventilation. Postoperative complications (7%), readmission (6%), and reoperation (6%) were infrequent, with no mortality. Conclusion COVID-19+ children requiring surgery have a favorable postoperative course and short-term outcomes compared to the reported adult experience. Type of study Prognosis Study. Level of evidence Level IV.

There is no required competency for pediatric vascular injury in surgical training. We sought to describe changes over time for surgical specialists operating on pediatric vascular trauma injuries at a pediatric trauma center.Charts were retrospectively reviewed for vascular trauma injuries at a freestanding children's hospital between 1993 and 2015. Data were collected on mechanism, injured vessel(s), operation(s) performed, and specialists performing operation. Surgical specialists were compared over time.Ninety-four patients (median age = 12) underwent 101 pediatric vascular trauma operations. There were significant differences in frequency of types of operations (primary repairs, graft repairs, and ligations) performed by pediatric, vascular, and orthopedic surgeons (P.001). The proportion of operations performed by vascular surgeons increased and those performed by pediatric surgeons decreased significantly over time.Various surgical specialists manage pediatric vascular trauma. With expansion of integrated residency programs, surgical specialists managing these patients in the future should be trained in both pediatric and vascular surgery.

We report an infant with COVID-19 who presented with bloody stools, lethargy and imaging findings significant for pneumatosis intestinalis. The infant was treated with conservative therapy, including resuscitation, bowel rest and intravenous antibiotics, successfully avoiding surgical intervention.

Optimal timing to begin feeds in neonates with gastroschisis remains unclear. We examined if bedside abdominal ultrasound for intestinal motility is a feasible tool to detect return of bowel function in neonates with gastroschisis.Neonates born with uncomplicated gastroschisis who underwent closure received daily ultrasound exams. Full motility was defined as peristalsis seen in all quadrants. Average length of time between abdominal wall closure and start of enteral feeds, full ultrasound motility, and clinical characteristics was compared using Student's t-tests.Seventeen patients were enrolled. No differences were found between motility on ultrasound and bowel movements, gastric residuals, or nonbilious residuals. Mean time to enteral feeds (11.82days) was significantly delayed compared to documentation of full motility on ultrasound (8.94days; p=0.012), consistent bowel movements (8.41days; p=0.006), low gastric residuals (9.47days; p0.001), and nonbilious residuals (9.18days; p0.001). In the single subject in which feeds were started before full motility was seen on ultrasound, feeds were subsequently discontinued because of emesis.Bedside abdominal ultrasound provides real-time evidence regarding intestinal motility and is a feasible tool to detect return of bowel function in neonates with gastroschisis. Future studies are needed to determine if abdominal ultrasound can shorten time to start of enteral feeds.III (diagnosis: nonconsecutive study).

Background Both the Medicare (MCR) and Medicaid (MCD) programs turn 50 this year. Medicare has developed a national resource-based payment methodology for physicians' services, with broad input by specialty societies, and MCD payments are set by individual states by various means. Study Design We have conducted the first national comparison of payment methodology of MCD vs MCR for procedures commonly delivered by general surgeons. Using the most recent Centers for Medicare and Medicaid Services' Medicare data for frequency of allowed charges for general surgeons, we selected the most frequently billed procedures and gathered data from the 50 states for MCD and MCR payments. We determined the "Medicaid discount" (MCD payment minus MCR payment) expressed as dollars and percent, as well as dollars paid per relative value of work. Results We have discovered wide variations in MCD payments among states for the same procedures, demonstrating unexplained "discounts" of MCD payments in relationship to MCR. We found that MCD payments show wide variations across the states, with many states paying far less than MCR for common, essential procedures. Conclusions These findings call into question the fairness of MCD reimbursement for general surgery services in the United States. This discount to MCR could act as a disincentive for surgeons to care for some patients, based on the state of residence. These unexplained discounts could have considerable long-term effects for patients dependent on the MCD program. Our study should act as a stimulus for states to examine their payment methodologies to provide more uniform and fairer payments for surgical procedures.
