Diagnostic Performance of Magnetic Resonance Imaging for Pediatric Ovarian Neoplasms: A Multi-Institutional Review.

STUDY OBJECTIVE: To assess the diagnostic performance of MRI to predict ovarian malignancy alone and compared with other diagnostic studies. METHODS: A retrospective analysis was conducted of patients aged 2-21 years who underwent ovarian mass resection between 2009 and 2021 at 11 pediatric hospitals. Sociodemographic information, clinical and imaging findings, tumor markers, and operative and pathology details were collected. Diagnostic performance for detecting malignancy was assessed by calculating sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for MRI with other diagnostic modalities. RESULTS: One thousand and fifty-three patients, with a median age of 14.6 years, underwent resection of an ovarian mass; 10% (110/1053) had malignant disease on pathology, and 13% (136/1053) underwent preoperative MRI. MRI sensitivity, specificity, PPV, and NPV were 60%, 94%, 60%, and 94%. Ultrasound sensitivity, specificity, PPV, and NPV were 31%, 99%, 73%, and 95%. Tumor marker sensitivity, specificity, PPV, and NPV were 90%, 46%, 22%, and 96%. MRI and ultrasound concordance was 88%, with sensitivity, specificity, PPV, and NPV of 33%, 99%, 75%, and 94%. MRI sensitivity in ultrasound-discordant cases was 100%. MRI and tumor marker concordance was 88% with sensitivity, specificity, PPV, and NPV of 100%, 86%, 64%, and 100%. MRI specificity in tumor marker-discordant cases was 100%. CONCLUSION: Diagnostic modalities used to assess ovarian neoplasms in pediatric patients typically agree. In cases of disagreement, MRI is more sensitive for malignancy than ultrasound and more specific than tumor markers. Selective use of MRI with preoperative ultrasound and tumor markers may be beneficial when the risk of malignancy is uncertain. CONCISE ABSTRACT: This retrospective review of 1053 patients aged 2-21 years who underwent ovarian mass resection between 2009 and 2021 at 11 pediatric hospitals found that ultrasound, tumor markers, and MRI tend to agree on benign vs malignant, but in cases of disagreement, MRI is more sensitive for malignancy than ultrasound.

Relationship between the COVID-19 pandemic and structural inequalities within the pediatric trauma population.

BACKGROUND: The COVID-19 pandemic disrupted social, political, and economic life across the world, shining a light on the vulnerability of many communities. The objective of this study was to assess injury patterns before and after implementation of stay-at-home orders (SHOs) between White children and children of color and across varying levels of vulnerability based upon children's home residence. METHODS: A multi-institutional retrospective study was conducted evaluating patients < 18 years with traumatic injuries. A "Control" cohort from an averaged March-September 2016-2019 time period was compared to patients injured after SHO initiation-September 2020 ("COVID" cohort). Interactions between race/ethnicity or social vulnerability index (SVI), a marker of neighborhood vulnerability and socioeconomic status, and the COVID-19 timeframe with regard to the outcomes of interest were assessed using likelihood ratio Chi-square tests. Differences in injury intent, type, and mechanism were then stratified and explored by race/ethnicity and SVI separately. RESULTS: A total of 47,385 patients met study inclusion. Significant interactions existed between race/ethnicity and the COVID-19 SHO period for intent (p < 0.001) and mechanism of injury (p < 0.001). There was also significant interaction between SVI and the COVID-19 SHO period for mechanism of injury (p = 0.01). Children of color experienced a significant increase in intentional (COVID 16.4% vs. Control 13.7%, p = 0.03) and firearm (COVID 9.0% vs. Control 5.2%, p < 0.001) injuries, but no change was seen among White children. Children from the most vulnerable neighborhoods suffered an increase in firearm injuries (COVID 11.1% vs. Control 6.1%, p = 0.001) with children from the least vulnerable neighborhoods having no change. All-terrain vehicle (ATV) and bicycle crashes increased for children of color (COVID 2.0% vs. Control 1.1%, p = 0.04 for ATV; COVID 6.7% vs. Control 4.8%, p = 0.02 for bicycle) and White children (COVID 9.6% vs. Control 6.2%, p < 0.001 for ATV; COVID 8.8% vs. Control 5.8%, p < 0.001 for bicycle). CONCLUSIONS: In contrast to White children and children from neighborhoods of lower vulnerability, children of color and children living in higher vulnerability neighborhoods experienced an increase in intentional and firearm-related injuries during the COVID-19 pandemic. Understanding inequities in trauma burden during times of stress is critical to directing resources and targeting intervention strategies.

Reducing Unnecessary Oophorectomies for Benign Ovarian Neoplasms in Pediatric Patients.

Importance: Although most ovarian masses in children and adolescents are benign, many are managed with oophorectomy, which may be unnecessary and can have lifelong negative effects on health. Objective: To evaluate the ability of a consensus-based preoperative risk stratification algorithm to discriminate between benign and malignant ovarian pathology and decrease unnecessary oophorectomies. Design, Setting, and Participants: Pre/post interventional study of a risk stratification algorithm in patients aged 6 to 21 years undergoing surgery for an ovarian mass in an inpatient setting in 11 children's hospitals in the United States between August 2018 and January 2021, with 1-year follow-up. Intervention: Implementation of a consensus-based, preoperative risk stratification algorithm with 6 months of preintervention assessment, 6 months of intervention adoption, and 18 months of intervention. The intervention adoption cohort was excluded from statistical comparisons. Main Outcomes and Measures: Unnecessary oophorectomies, defined as oophorectomy for a benign ovarian neoplasm based on final pathology or mass resolution. Results: A total of 519 patients with a median age of 15.1 (IQR, 13.0-16.8) years were included in 3 phases: 96 in the preintervention phase (median age, 15.4 [IQR, 13.4-17.2] years; 11.5% non-Hispanic Black; 68.8% non-Hispanic White); 105 in the adoption phase; and 318 in the intervention phase (median age, 15.0 [IQR, 12.9-16.6)] years; 13.8% non-Hispanic Black; 53.5% non-Hispanic White). Benign disease was present in 93 (96.9%) in the preintervention cohort and 298 (93.7%) in the intervention cohort. The percentage of unnecessary oophorectomies decreased from 16.1% (15/93) preintervention to 8.4% (25/298) during the intervention (absolute reduction, 7.7% [95% CI, 0.4%-15.9%]; P = .03). Algorithm test performance for identifying benign lesions in the intervention cohort resulted in a sensitivity of 91.6% (95% CI, 88.5%-94.8%), a specificity of 90.0% (95% CI, 76.9%-100%), a positive predictive value of 99.3% (95% CI, 98.3%-100%), and a negative predictive value of 41.9% (95% CI, 27.1%-56.6%). The proportion of misclassification in the intervention phase (malignant disease treated with ovary-sparing surgery) was 0.7%. Algorithm adherence during the intervention phase was 95.0%, with fidelity of 81.8%. Conclusions and Relevance: Unnecessary oophorectomies decreased with use of a preoperative risk stratification algorithm to identify lesions with a high likelihood of benign pathology that are appropriate for ovary-sparing surgery. Adoption of this algorithm might prevent unnecessary oophorectomy during adolescence and its lifelong consequences. Further studies are needed to determine barriers to algorithm adherence.

Evaluating the Regional Differences in Pediatric Injury Patterns During the COVID-19 Pandemic.

INTRODUCTION: Reports of pediatric injury patterns during the COVID-19 pandemic are conflicting and lack the granularity to explore differences across regions. We hypothesized there would be considerable variation in injury patterns across pediatric trauma centers in the United States. MATERIALS AND METHODS: A multicenter, retrospective study evaluating patients <18 y old with traumatic injuries meeting National Trauma Data Bank criteria was performed. Patients injured after stay-at-home orders through September 2020 ("COVID" cohort) were compared to "Historical" controls from an averaged period of equivalent dates in 2016-2019. Differences in injury type, intent, and mechanism were explored at the site level. RESULTS: 47,385 pediatric trauma patients were included. Overall trauma volume increased during the COVID cohort compared to the Historical (COVID 7068 patients versus Historical 5891 patients); however, some sites demonstrated a decrease in overall trauma of 25% while others had an increase of over 33%. Bicycle injuries increased at every site, with a range in percent change from 24% to 135% increase. Although the greatest net increase was due to blunt injuries, there was a greater relative increase in penetrating injuries at 7/9 sites, with a range in percent change from a 110% increase to a 69% decrease. CONCLUSIONS: There was considerable discrepancy in pediatric injury patterns at the individual site level, perhaps suggesting a variable impact of the specific sociopolitical climate and pandemic policies of each catchment area. Investigation of the unique response of the community during times of stress at pediatric trauma centers is warranted to be better prepared for future environmental stressors.

Natural history and consequence of patent processus vaginalis: An interim analysis from a multi-institutional prospective observational study.

BACKGROUND: The prevalence and natural history of patent processus vaginalis (PPV) are unknown. An interim analysis was performed of a multi-institutional, prospective, observational study in neonates undergoing laparoscopic pyloromyotomy during which bilateral inguinal canals were evaluated. METHODS: Infants under 4 months undergoing laparoscopic pyloromyotomy were enrolled at 8 children's hospitals. The presence of a PPV was evaluated and measurements recorded. Patients with a PPV are undergoing annual phone follow-up to 18 years of age. Interim analysis was performed. RESULTS: In a cohort of 610 patient, 80 did not have a PPV examined, 4 had consent issues and were excluded, leaving 526 patients. Of these, 433 (82%) were male, median age 1.2 months (IQR 0.9, 1.6), median weight 3.89 kg (IQR 3.4, 4.46), and EGA 39 weeks (IQR 37, 40). There were 283 PPVs, 132 bilateral (47%), 116 right (41%), and 35 left (12%). Patients with a PPV were significantly younger (1.1 months (IQR 0.9, 1.5) vs 1.3 months (IQR 0.9, 1.7), p=0.02), weighed less (3.76kg (IQR 3.35, 4.26) vs 3.9kg (IQR 3.4, 4.5) p=0.03) and had a significantly lower EGA at birth (38 weeks (IQR 37, 40) vs 39 weeks (IQR 38, 40) p=0.003). Of 246 eligible infants, 208 (85%) responded to at least one annual follow-up. Two patients had an inguinal hernia repair for a symptomatic hernia, 49- and 51-days post pyloromyotomy. One had an orchiopexy and incidental inguinal hernia repair 120 days post pyloromyotomy; for a total of 3 (1.2%) hernia repairs. No additional hernias were identified in 116 patients with the PPV patients who have been followed for > 1 year. CONCLUSIONS: The presence of a PPV at the time of pyloromyotomy is common but the need for hernia repair is rare within the first year of life. Continued long-term longitudinal follow-up of this cohort is needed. LEVEL OF EVIDENCE: II.

Thoracoscopy versus thoracotomy for esophageal atresia and tracheoesophageal fistula: Outcomes from the Midwest Pediatric Surgery Consortium.

BACKGROUND/PURPOSE: Controversy persists regarding the ideal surgical approach for repair of esophageal atresia with tracheoesophageal fistula (EA/TEF). We examined complications and outcomes of infants undergoing thoracoscopy and thoracotomy for repair of Type C EA/TEF using propensity score-based overlap weights to minimize the effects of selection bias. METHODS: Secondary analysis of two databases from multicenter retrospective and prospective studies examining outcomes of infants with proximal EA and distal TEF who underwent repair at 11 institutions was performed based on surgical approach. Regression analysis using propensity score-based overlap weights was utilized to evaluate outcomes of patients undergoing thoracotomy or thoracoscopy for Type C EA/TEF repair. RESULTS: Of 504 patients included, 448 (89%) underwent thoracotomy and 56 (11%) thoracoscopy. Patients undergoing thoracoscopy were more likely to be full term (37.9 vs. 36.3 weeks estimated gestational age, p < 0.001), have a higher weight at operative repair (2.9 vs. 2.6 kg, p < 0.001), and less likely to have congenital heart disease (16% vs. 39%, p < 0.001). Postoperative stricture rate did not differ by approach, 29 (52%) thoracoscopy and 198 (44%) thoracotomy (p = 0.42). Similarly, there was no significant difference in time from surgery to stricture formation (p > 0.26). Regression analysis using propensity score-based overlap weighting found no significant difference in the odds of vocal cord paresis or paralysis (OR 1.087 p = 0.885), odds of anastomotic leak (OR 1.683 p = 0.123), the hazard of time to anastomotic stricture (HR 1.204 p = 0.378), or the number of dilations (IRR 1.182 p = 0.519) between thoracoscopy and thoracotomy. CONCLUSION: Infants undergoing thoracoscopic repair of Type C EA/TEF are more commonly full term, with higher weight at repair, and without congenital heart disease as compared to infants repaired via thoracotomy. Utilizing propensity score-based overlap weighting to minimize the effects of selection bias, we found no significant difference in complications based on surgical approach. However, our study may be underpowered to detect such outcome differences owing to the small number of infants undergoing thoracoscopic repair. LEVEL OF EVIDENCE: Level III.

Pediatric injury trends and relationships with social vulnerability during the COVID-19 pandemic: A multi-institutional analysis.

BACKGROUND: The impact of the COVID-19 pandemic on pediatric injury, particularly relative to a community's vulnerability, is unknown. The objective of this study was to describe the change in pediatric injury during the first 6 months of the COVID-19 pandemic compared with prior years, focusing on intentional injury relative to the social vulnerability index (SVI). METHODS: All patients younger than 18 years meeting inclusion criteria for the National Trauma Data Bank between January 1, 2016, and September 30, 2020, at nine Level I pediatric trauma centers were included. The COVID cohort (children injured in the first 6 months of the pandemic) was compared with an averaged historical cohort (corresponding dates, 2016-2019). Demographic and injury characteristics and hospital-based outcomes were compared. Multivariable logistic regression was used to estimate the adjusted odds of intentional injury associated with SVI, moderated by exposure to the pandemic. Interrupted time series analysis with autoregressive integrated moving average modeling was used to predict expected injury patterns. Volume trends and observed versus expected rates of injury were analyzed. RESULTS: There were 47,385 patients that met inclusion criteria, with 8,991 treated in 2020 and 38,394 treated in 2016 to 2019. The COVID cohort included 7,068 patients and the averaged historical cohort included 5,891 patients (SD, 472), indicating a 20% increase in pediatric injury ( p = 0.031). Penetrating injuries increased (722 [10.2%] COVID vs. 421 [8.0%] historical; p < 0.001), specifically firearm injuries (163 [2.3%] COVID vs. 105 [1.8%] historical; p = 0.043). Bicycle collisions (505 [26.3%] COVID vs. 261 [18.2%] historical; p < 0.001) and collisions on other land transportation (e.g., all-terrain vehicles) (525 [27.3%] COVID vs. 280 [19.5%] historical; p < 0.001) also increased. Overall, SVI was associated with intentional injury (odds ratio, 7.9; 95% confidence interval, 6.5-9.8), a relationship which increased during the pandemic. CONCLUSION: Pediatric injury increased during the pandemic across multiple sites and states. The relationship between increased vulnerability and intentional injury increased during the pandemic. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

Use and Accuracy of Intraoperative Frozen Section Analysis for Ovarian Masses in Children and Adolescents.

STUDY OBJECTIVE: Describe the current practice patterns and diagnostic accuracy of frozen section (FS) pathology for children and adolescents with ovarian masses DESIGN: Prospective cohort study from 2018 to 2021 SETTING: Eleven children's hospitals PARTICIPANTS: Females age 6-21 years undergoing surgical management of an ovarian mass INTERVENTIONS: Obtaining intraoperative FS pathology MAIN OUTCOME MEASURE: Diagnostic accuracy of FS pathology RESULTS: Of 691 patients who underwent surgical management of an ovarian mass, FS was performed in 27 (3.9%), of which 9 (33.3%) had a final malignant pathology. Among FS patients, 12 of 27 (44.4%) underwent ovary-sparing surgery, and 15 of 27 (55.5%) underwent oophorectomy with or without other procedures. FS results were disparate from final pathology in 7 of 27 (25.9%) cases. FS had a sensitivity of 44.4% and specificity of 94.4% for identifying malignancy, with a c-statistic of 0.69. Malignant diagnoses missed on FS included serous borderline tumor (n = 1), mucinous borderline tumor (n = 2), mucinous carcinoma (n = 1), and immature teratoma (n = 1). FS did not guide intervention in 10 of 27 (37.0%) patients: 9 with benign FS underwent oophorectomy, and 1 with malignant FS did not undergo oophorectomy. Of the 9 patients who underwent oophorectomy with benign FS, 5 (55.6%) had benign and 4 (44.4%) had malignant final pathology. CONCLUSIONS: FSs are infrequently utilized for pediatric and adolescent ovarian masses and could be inaccurate for predicting malignancy and guiding operative decision-making. We recommend continued assessment and refinement of guidance before any standardization of use of FS to assist with intraoperative decision-making for surgical resection and staging in children and adolescents with ovarian masses.

A Multi-institutional Study Evaluating Pediatric Burn Injuries During the COVID-19 Pandemic.

During the COVID-19 pandemic, children were out of school due to Stay-at-Home Orders. The objective of this study was to investigate how the COVID-19 pandemic may have impacted the incidence of burn injuries in children. Eight Level I Pediatric Trauma Centers participated in a retrospective study evaluating children <18 years old with traumatic injuries defined by the National Trauma Data Bank. Patients with burn injuries were identified by ICD-10 codes. Historical controls from March to September 2019 ("Control" cohort) were compared to patients injured after the start of the COVID-19 pandemic from March to September 2020 ("COVID" cohort). A total of 12,549 pediatric trauma patients were included, of which 916 patients had burn injuries. Burn injuries increased after the start of the pandemic (COVID 522/6711 [7.8%] vs Control 394/5838 [6.7%], P = .03). There were no significant differences in age, race, insurance status, burn severity, injury severity score, intent or location of injury, and occurrence on a weekday or weekend between cohorts. There was an increase in flame burns (COVID 140/522 [26.8%] vs Control 75/394 [19.0%], P = .01) and a decrease in contact burns (COVID 118/522 [22.6%] vs Control 112/394 [28.4%], P = .05). More patients were transferred from an outside institution (COVID 315/522 patients [60.3%] vs Control 208/394 patients [52.8%], P = .02), and intensive care unit length of stay increased (COVID median 3.5 days [interquartile range 2.0-11.0] vs Control median 3.0 days [interquartile range 1.0-4.0], P = .05). Pediatric burn injuries increased after the start of the COVID-19 pandemic despite Stay-at-Home Orders intended to optimize health and increase public safety.

Pediatric Injury Transfer Patterns During the COVID-19 Pandemic: An Interrupted time Series Analysis.

INTRODUCTION: With the expected surge of adult patients with COVID-19, the Children's Hospital Association recommended a tiered approach to divert children to pediatric centers. Our objective was understanding changes in interfacility transfer to Pediatric Trauma Centers (PTCs) during the first 6 mo of the pandemic. METHODS: Children aged < 18 y injured between January 1, 2016 and September 30, 2020, who met National Trauma Databank inclusion criteria from 9 PTCs were included. An interrupted time-series analysis was used to estimate an expected number of transferred patients compared to observed volume. The "COVID" cohort was compared to a historical cohort (historical average [HA]), using an average across 2016-2019. Site-based differences in transfer volume, demographics, injury characteristics, and hospital-based outcomes were compared between cohorts. RESULTS: Twenty seven thousand thirty one/47,382 injured patients (57.05%) were transferred to a participating PTC during the study period. Of the COVID cohort, 65.4% (4620/7067) were transferred, compared to 55.7% (3281/5888) of the HA (P < 0.001). There was a decrease in 15-y-old to 17-y-old patients (10.43% COVID versus 12.64% HA, P = 0.003). More patients in the COVID cohort had injury severity scores ≤ 15 (93.25% COVID versus 87.63% HA, P < 0.001). More patients were discharged home after transfer (31.80% COVID versus 21.83% HA, P < 0.001). CONCLUSIONS: Transferred trauma patients to Level I PTC increased during the COVID-19 pandemic. The proportion of transferred patients discharged from emergency departments increased. Pediatric trauma transfers may be a surrogate for referring emergency department capacity and resources and a measure of pediatric trauma triage capability.

Disparities in the Management of Pediatric Breast Masses.

INTRODUCTION: Disparities in surgical management have been documented across a range of disease processes. The objective of this study was to investigate sociodemographic disparities in young females undergoing excision of a breast mass. METHODS: A retrospective study of females aged 10-21 y who underwent surgery for a breast lesion across eleven pediatric hospitals from 2011 to 2016 was performed. Differences in patient characteristics, workup, management, and pathology by race/ethnicity, insurance status, median neighborhood income, and urbanicity were evaluated with bivariate and multivariable regression analyses. RESULTS: A total of 454 females were included, with a median age of 16 y interquartile range (IQR: 3). 44% of patients were nonHispanic (NH) Black, 40% were NH White, and 7% were Hispanic. 50% of patients had private insurance, 39% had public insurance, and 9% had other/unknown insurance status. Median neighborhood income was $49,974, and 88% of patients resided in a metropolitan area. NH Whites have 4.5 times the odds of undergoing preoperative fine needle aspiration or core needle biopsy compared to NH Blacks (CI: 2.0, 10.0). No differences in time to surgery from the initial imaging study, size of the lesion, or pathology were observed on multivariable analysis. CONCLUSIONS: We found no significant differences by race/ethnicity, insurance status, household income, or urbanicity in the time to surgery after the initial imaging study. The only significant disparity noted on multivariable analysis was NH White patients were more likely to undergo preoperative biopsy than were NH Black patients; however, the utility of biopsy in pediatric breast masses is not well established.

The COVID-19 pandemic and associated rise in pediatric firearm injuries: A multi-institutional study.

BACKGROUND: Firearm sales in the United States (U.S.) markedly increased during the COVID-19 pandemic. Our objective was to determine if firearm injuries in children were associated with stay-at-home orders (SHO) during the COVID-19 pandemic. We hypothesized there would be an increase in pediatric firearm injuries during SHO. METHODS: This was a multi institutional, retrospective study of institutional trauma registries. Patients <18 years with traumatic injuries meeting National Trauma Data Bank (NTDB) criteria were included. A "COVID" cohort, defined as time from initiation of state SHO through September 30, 2020 was compared to "Historical" controls from an averaged period of corresponding dates in 2016-2019. An interrupted time series analysis (ITSA) was utilized to evaluate the association of the U.S. declaration of a national state of emergency with pediatric firearm injuries. RESULTS: Nine Level I pediatric trauma centers were included, contributing 48,111 pediatric trauma patients, of which 1,090 patients (2.3%) suffered firearm injuries. There was a significant increase in the proportion of firearm injuries in the COVID cohort (COVID 3.04% vs. Historical 1.83%; p < 0.001). There was an increased cumulative burden of firearm injuries in 2020 compared to a historical average. ITSA showed an 87% increase in the observed rate of firearm injuries above expected after the declaration of a nationwide emergency (p < 0.001). CONCLUSION: The proportion of firearm injuries affecting children increased during the COVID-19 pandemic. The pandemic was associated with an increase in pediatric firearm injuries above expected rates based on historical patterns.

Demographic and Clinical Characteristics Associated With the Failure of Nonoperative Management of Uncomplicated Appendicitis in Children: Secondary Analysis of a Nonrandomized Clinical Trial.

Importance: The factors associated with the failure of nonoperative management of appendicitis and the differences in patient-reported outcomes between successful and unsuccessful nonoperative management remain unknown. Objectives: To investigate factors associated with the failure of nonoperative management of appendicitis and compare patient-reported outcomes between patients whose treatment succeeded and those whose treatment failed. Design, Setting, and Participants: This study was a planned subgroup secondary analysis conducted in 10 children's hospitals that included 370 children aged 7 to 17 years with uncomplicated appendicitis enrolled in a prospective, nonrandomized clinical trial between May 1, 2015, and October 31, 2018, with 1-year follow-up comparing nonoperative management with antibiotics vs surgery for uncomplicated appendicitis. Statistical analysis was performed from November 1, 2019, to February 12, 2022. Interventions: Nonoperative management with antibiotics vs surgery. Main Outcomes and Measures: Failure of nonoperative management and patient-reported outcomes. The relative risk (RR) of failure based on sociodemographic and clinical characteristics was calculated. Patient-reported outcomes were compared based on the success or failure of nonoperative management. Results: Of 370 patients (34.6% of 1068 total patients; 229 boys [61.9%]; median age, 12.3 years [IQR, 10.0-14.6 years]) enrolled in the nonoperative group, treatment failure occurred for 125 patients (33.8%) at 1 year, with 53 patients (14.3%) undergoing appendectomy during initial hospitalization and 72 patients (19.5%) experiencing delayed treatment failure after hospital discharge. Higher patient-reported pain at presentation was associated with increased risk of in-hospital treatment failure (RR, 2.1 [95% CI, 1.0-4.4]) but not delayed treatment failure (RR, 1.3 [95% CI, 0.7-2.3]) or overall treatment failure at 1 year (RR, 1.5 [95% CI, 1.0-2.2]). Pain duration greater than 24 hours was associated with decreased risk of delayed treatment failure (RR, 0.3 [95% CI, 0.1-1.0]) but not in-hospital treatment failure (RR, 1.2 [95% CI, 0.5-2.7]) or treatment failure at 1 year (RR, 0.7 [95% CI, 0.4-1.2]). There was no increased risk of treatment failure associated with age, white blood cell count, sex, race, ethnicity, primary language, insurance status, transfer status, symptoms at presentation, or imaging results. Health care satisfaction at 30 days and patient-reported, health-related quality of life at 30 days and 1 year were not different. Satisfaction with the decision was higher with successful nonoperative management at 30 days (28.0 vs 27.0; difference, 1.0 [95% CI, 0.01-2.0]) and 1 year (28.1 vs 27.0; difference, 1.1 [95% CI, 0.2-2.0]). Conclusions and Relevance: This analysis suggests that a higher pain level at presentation was associated with a higher risk of initial failure of nonoperative management and that a longer duration of pain was associated with lower risk of delayed treatment failure. Although satisfaction was high in both groups, satisfaction with the treatment decision was higher among patients with successful nonoperative management at 1 year. Trial Registration: ClinicalTrials.gov Identifier: NCT02271932.

Evaluating the risk of peri-umbilical hernia after sutured or sutureless gastroschisis closure.

INTRODUCTION: We evaluate the incidence, outcomes, and management of peri­umbilical hernias after sutured or sutureless gastroschisis closure. METHODS: A retrospective, longitudinal follow-up of neonates with gastroschisis who underwent closure at 11 children's hospitals from 2013 to 2016 was performed. Patient encounters were reviewed through 2019 to identify the presence of a peri­umbilical hernia, time to spontaneous closure or repair, and associated complications. RESULTS: Of 397 patients, 375 had follow-up data. Sutured closure was performed in 305 (81.3%). A total of 310 (82.7%) infants had uncomplicated gastroschisis. Peri-umbilical hernia incidence after gastroschisis closure was 22.7% overall within a median follow-up of 2.5 years [IQR 1.3,3.9], and higher in those with uncomplicated gastroschisis who underwent primary vs. silo assisted closure (53.0% vs. 17.2%, p< 0.001). At follow-up, 50.0% of sutureless closures had a persistent hernia, while 16.4% of sutured closures had a postoperative hernia of the fascial defect (50.0% vs. 16.4%, p< 0.001). Spontaneous closure was observed in 38.8% of patients within a median of 17 months [9,26] and most frequently observed in those who underwent a sutureless primary closure (52.2%). Twenty-seven patients (31.8%) underwent operative repair within a median of 13 months [7,23.5]. Rate and interval of spontaneous closure or repair were similar between the sutured and sutureless closure groups, with no difference between those who underwent primary vs. silo assisted closure. CONCLUSION: Peri-umbilical hernias after sutured or sutureless gastroschisis closure may be safely observed similar to congenital umbilical hernias as spontaneous closure occurs, with minimal complications and no additional risk with either closure approach. LEVELS OF EVIDENCE: Level II.

Same-day discharge after appendectomy for uncomplicated appendicitis in children: Potential barriers to increased utilization.

BACKGROUND: Utilization of same-day discharge (SDD) after appendectomy for uncomplicated appendicitis (UA) was closely examined to explore potential barriers to greater use of SDD. METHODS: Children (≤18 years) who underwent appendectomy for UA between 2015 and 2019 at a tertiary care children's hospital were reviewed. Associations with SDD were evaluated using multivariable regression models. RESULTS: Among 973 children, SDD was less frequently utilized after appendectomy performed between 12pm and 5pm (aOR 0.14, p < 0.001) and after 5pm (aOR 0.01, p < 0.001) compared to before 12pm. SDD utilization was also less frequent in those from lower resource neighborhoods (adjusted odds ratio [aOR] 0.90 per decile increase in Area Deprivation Index, p = 0.04), females (aOR 0.53, p = 0.005), and patients residing 30-60 min away (aOR 0.56, p = 0.04) compared to <30 min away. CONCLUSIONS: SDD utilization was primarily impacted by operative timing and socioeconomic and travel factors, focuses for quality improvement efforts to further increase utilization of SDD.

Acid suppression duration does not alter anastomotic stricture rates after esophageal atresia with distal tracheoesophageal fistula repair: A prospective multi-institutional cohort study.

INTRODUCTION: Anastomotic stricture is the most common complication after esophageal atresia (EA) repair. We sought to determine if postoperative acid suppression is associated with reduced stricture formation. METHODS: A prospective, multi-institutional cohort study of infants undergoing primary EA repair from 2016 to 2020 was performed. Landmark analysis and multivariate Cox regression were used to explore if initial duration of acid suppression was associated with stricture formation at hospital discharge (DC), 3-, 6-, and 9-months postoperatively. RESULTS: Of 156 patients, 79 (51%) developed strictures and 60 (76%) strictures occurred within three months following repair. Acid suppression was used in 141 patients (90%). Landmark analysis showed acid suppression was not associated with reduction in initial stricture formation at DC, 3-, 6- and 9-months, respectively (p = 0.19-0.95). Multivariate regression demonstrated use of a transanastomotic tube was significantly associated with stricture formation at DC (Hazard Ratio (HR) = 2.21 (95% CI 1.24-3.95, p<0.01) and 3-months (HR 5.31, 95% CI 1.65-17.16, p<0.01). There was no association between acid suppression duration and stricture formation. CONCLUSION: No association between the duration of postoperative acid suppression and anastomotic stricture was observed. Transanastomotic tube use increased the risk of anastomotic strictures at hospital discharge and 3 months after repair.

Laparoscopy versus laparotomy for pediatric ovarian dermoids.

BACKGROUND: With increased surgeon comfort using laparoscopy, we hypothesized resection of pediatric ovarian dermoids using laparoscopy would yield a shorter length of stay and no increase in morbidity or recurrence compared to laparotomy. METHODS: A retrospective review was performed amongst eleven pediatric hospitals. Patients aged 2 to 21 who underwent resection of an ovarian dermoid from 2010 to 2020 were included. Patient characteristics, operative details, and outcomes by approach were evaluated using Chi-squared and Wilcoxon-Mann tests. RESULTS: 466 patients were included, with a median age of 14.4 and median follow-up of 4.0 months. 279 patients underwent laparoscopy (60%), 139 laparotomy (30%), and 48 laparoscopy converted to laparotomy (10%). There were no differences in rates of tumor spillage by approach (p = 0.15). 65% underwent ovarian-sparing surgery and 35% underwent oophorectomy. Length of stay was significantly shorter amongst patients who underwent laparoscopy (1 day versus 2 days for laparotomy and converted, p<0.0001). There were no differences in rates of suspected recurrence or reoperation (p = 0.19 and p = 0.57, respectively). CONCLUSION: Patients who underwent laparoscopy experienced no differences in the rates of tumor spillage, recurrence, or reoperation and had a shorter length of stay compared to laparotomy. Laparoscopy is an acceptable approach for resection of pediatric ovarian dermoids.

Impact of "Stay-at-Home" orders on non-accidental trauma: A multi-institutional study.

BACKGROUND: It is unclear how Stay-at-Home Orders (SHO) of the COVID-19 pandemic impacted the welfare of children and rates of non-accidental trauma (NAT). We hypothesized that NAT would initially decrease during the SHO as children did not have access to mandatory reporters, and then increase as physicians' offices and schools reopened. METHODS: A multicenter study evaluating patients <18 years with ICD-10 Diagnosis and/or External Cause of Injury codes meeting criteria for NAT. "Historical" controls from an averaged period of March-September 2016-2019 were compared to patients injured March-September 2020, after the implementation of SHO ("COVID" cohort). An interrupted time series analysis was utilized to evaluate the effects of SHO implementation. RESULTS: Nine Level I pediatric trauma centers contributed 2064 patients meeting NAT criteria. During initial SHO, NAT rates dropped below what was expected based on historical trends; however, thereafter the rate increased above the expected. The COVID cohort experienced a significant increase in the proportion of NAT patients age ≥5 years, minority children, and least resourced as determined by social vulnerability index (SVI). CONCLUSIONS: The COVID-19 pandemic affected the presentation of children with NAT to the hospital. In times of public health crisis, maintaining systems of protection for children remain essential. LEVEL OF EVIDENCE: III.

Multi-Institutional Review of the Preoperative Diagnostic Accuracy for Pediatric Ovarian Mature Cystic Teratomas.

STUDY OBJECTIVE: To assess the preoperative imaging impression and surgeon diagnostic accuracy for pediatric ovarian mature cystic teratomas (MCTs) DESIGN: Retrospective review SETTING: Eleven pediatric hospitals PARTICIPANTS: Patients ages 2 to 21 who underwent surgical management of an ovarian neoplasm or adnexal torsion with an associated ovarian lesion INTERVENTION: None MAIN OUTCOME MEASURES: Preoperative imaging impression, surgeon diagnosis, tumor markers, and pathology RESULTS: Our cohort included 946 females. Final pathology identified 422 (45%) MCTs, 405 (43%) other benign pathologies, and 119 (12%) malignancies. Preoperative imaging impression for MCTs had a 70% sensitivity, 92% specificity, 88% positive predictive value (PPV), and 79% negative predictive value (NPV). For the preoperative surgeon diagnosis, sensitivity was 59%, specificity 96%, PPV 92%, and NPV 74%. Some measures of diagnostic accuracy were affected by the presence of torsion, size of the lesion on imaging, imaging modality, and surgeon specialty. Of the 352 masses preoperatively thought to be MCTs, 14 were malignancies (4%). Eleven patients with inaccurately diagnosed malignancies had tumor markers evaluated and 82% had at least 1 elevated tumor marker, compared with 49% of those with MCTs. CONCLUSIONS: Diagnostic accuracy for the preoperative imaging impression and surgeon diagnosis is lower than expected for pediatric ovarian MCTs. For all ovarian neoplasms, preoperative risk assessment including a panel of tumor markers and a multidisciplinary review is recommended. This process could minimize the risk of misdiagnosis and improve operative planning to maximize the use of ovarian-sparing surgery for benign lesions and allow for appropriate resection and staging for lesions suspected to be malignant.

Does Use of a Feeding Protocol Change Outcomes in Gastroschisis? A Report from the Midwest Pediatric Surgery Consortium.

INTRODUCTION: Gastroschisis feeding practices vary. Standardized neonatal feeding protocols have been demonstrated to improve nutritional outcomes. We report outcomes of infants with gastroschisis that were fed with and without a protocol. MATERIALS AND METHODS: A retrospective study of neonates with uncomplicated gastroschisis at 11 children's hospitals from 2013 to 2016 was performed.Outcomes of infants fed via institutional-specific protocols were compared with those fed without a protocol. Subgroup analyses of protocol use with immediate versus delayed closure and with sutured versus sutureless closure were conducted. RESULTS: Among 315 neonates, protocol-based feeding was utilized in 204 (65%) while no feeding protocol was used in 111 (35%). There were less surgical site infections (SSI) in those fed with a protocol (7 vs. 16%, p = 0.019). There were no differences in TPN duration, time to initial oral intake, time to goal feeds, ventilator use, peripherally inserted central catheter line deep venous thromboses, or length of stay. Of those fed via protocol, less SSIs occurred in those who underwent sutured closure (9 vs. 19%, p = 0.026). Further analyses based on closure timing or closure method did not demonstrate any significant differences. CONCLUSION: Across this multi-institutional cohort of infants with uncomplicated gastroschisis, there were more SSIs in those fed without an institutional-based feeding protocol but no differences in other outcomes.
