INTRODUCTION/BACKGROUND:Pediatric surgeons provide a broad array of medical and surgical services in diverse care environments across various institutional settings. This spectrum includes large, free-standing children's hospitals and small pediatric units within predominantly adult hospitals. However, it is unclear how differences in hospital setting affect pediatric surgical practice and the delivery of pediatric surgical care. METHODS:To better understand the effect hospital setting may have on the delivery of pediatric surgical care, a survey was administered to pediatric surgeons serving on surgical committees of the American Academy of Pediatrics, Section on Surgery, to gather perspectives on the hospital settings where they provide care. Data were categorized based on hospital type including free-standing children's hospitals, children's hospital/unit within an adult hospital, and children's hospital with an adjacent adult hospital. RESULTS:A total of 60 pediatric surgeons responded to the survey (44% response rate), 45% from free-standing children's hospitals. Our findings revealed distinct advantages and disadvantages perceived by surgeons associated with each type of hospital setting. Notably, access to dedicated pediatric operating rooms and adult surgical specialists was highlighted as particularly beneficial for pediatric surgical care delivery. Access to various subspecialties varied depending on the hospital setting. CONCLUSIONS:Collectively, these data provide valuable insights on factors that foundationally impact pediatric surgical care delivery, which may vary by hospital setting. Access to pediatric operating rooms, pediatric subspecialists, and adult surgeons were identified as key determinants of effective pediatric surgical care. These data may provide a roadmap in the advocacy for key resources to enhance the surgical care of children.

BACKGROUND:The delivery of pediatric surgical care to newborns varies based on neonatal intensive care unit (NICU) coverage. We aimed to describe the current national coverage landscape and assess pediatric surgeons' perspectives on the optimal management of infants at outlying NICUs. METHODS:The AAP Delivery of Surgical Care Committee administered a web-based survey to pediatric surgery division chiefs at Children's Hospital Association practices. Responses were analyzed using appropriate nonparametric and categorical statistical tests, with significance set at p<0.05. RESULTS:Fifty-two division chiefs responded (28.9%); 26 (50% reporting covering one or more outlying NICUs. Of these outlying NICUS, 76% were Level III. Just over half (51%) had no affiliation with the surgeons' primary hospital. Case volumes were low, with only 5 NICUs (15%) performing more than 25 operations annually. Factors influencing decisions to operate at outlying NICUs included rapport with neonatologists, NICU level designation, transfer capability, and availability of pediatric anesthesiology. The capacity of outlying NICUs to care for infants with index surgical diagnoses varied based on specific diagnosis. Over half of respondents endorsed transfer to the primary center as the optimal location for care for all procedures except gastrostomy tube placement and central venous access. CONCLUSION/CONCLUSIONS:Half of surveyed pediatric surgery groups provide coverage to one or more outlying NICUs despite low reported case volumes. A clear disconnect exists between pediatric surgeons' views on location for optimal care and sites of current care provision. These findings underscore the need for regionalized strategies to optimize surgical care of these infants.

BACKGROUND:Perinatal ovarian cysts may spontaneously resolve or cause ovarian torsion. Cyst size and appearance often guide surgical decision making. The natural history of these cysts and impact of perinatal interventions on ovarian outcomes remain unclear. We investigated the association of various clinical parameters with operative intervention and ovarian loss. METHODS:Infants with ovarian cysts meeting our definition of perinatal (diagnosed between 15 weeks gestational age and 1 year) from November 2006-January 2022 were identified. Cysts were characterized by size, morphology, laterality, and evolution. Outcome measures included resolution, ovarian loss, and operative intervention. Mann-Whitney U and Fisher exact tests were used. Optimal maximal size cutoffs were obtained using ROC curves. RESULTS:Sixty-two female patients with perinatal ovarian cysts were identified. Spontaneous resolution occurred in 35, prenatally and postnatally, with follow-up length averaging 186 days. Of 18 undergoing cystectomies, 9 revealed non-viable ovaries. Overall ovarian loss rate was 29%. Loss occurred more frequently with large, complex, and right-sided cysts (P < 0.05) but some complex cysts also resolved spontaneously. Operative intervention occurred more frequently with larger cysts (P=<0.001) and was associated with ovarian salvage when performed earlier (P = 0.008) on larger cysts (P = 0.02). Maximal cyst diameter > 4.05 cm predicted ovarian loss with 78% sensitivity, 64% specificity (AUC = 0.67,95%CI = 0.54-0.81, P = 0.04). Maximal cyst diameter > 4.55 cm predicted surgery with 83% sensitivity, 82% specificity (AUC = 0.86,95%CI = 0.77-0.96, P < 0.001). CONCLUSIONS:29% of perinatal ovarian cysts resulted in ovarian loss. 56% resolved spontaneously (prenatal and postnatal resolution) including some complex cysts. Cysts that were postnatally complex and maximally > 4 cm had higher rates of ovarian loss and operative intervention. Earlier postnatal operative intervention was associated with ovarian preservation. Standardized imaging (such as the IOTA terminology) and management protocols are needed to better understand behavior and improve treatment of these cysts.

OBJECTIVES/OBJECTIVE:To evaluate ECMO-related morbidity and mortality between Early-term (ET) and Full-term (FT) infants. METHODS:weeks were classified as FT. Primary outcomes were ECMO survival and survival to discharge. Secondary outcomes were complications while on ECMO. Data were analyzed using Mann-Whitney U and Fisher's Exact testing. Logistic regression was performed to assess odds of ECMO survival for factors noted to be significantly different between groups. RESULTS:Of 2,551 infants who met inclusion criteria based on gestational age, we identified 805 (32 %) ET and 1,746 (68 %) FT infants. ET infants had significantly lower ECMO survival (90 vs. 94 %, p<0.01) and survival to discharge (80 vs. 88 %, p<0.01), more neurologic complications on ECMO (15 vs. 12 %, p=0.024), and increased need for hemofiltration (33 vs. 29 %, p=0.033). There were no statistically significant differences between groups in mechanical, hemorrhagic, infectious, metabolic, renal, pulmonary, limb, or cardiovascular complications while on ECMO. Multiple logistic regression showed that ET gestational age, development of neurologic complications on ECMO, and need for hemofiltration are independent negative predictors of ECMO survival. CONCLUSIONS:ET gestational age is an independent risk factor for worse ECMO outcomes and survival in comparison to FT infants, highlighting the vulnerability of this population.

BACKGROUND:Despite evidence supporting selective use of non-operative management (NOM) for children with uncomplicated, acute appendicitis, no consensus exists regarding its clinical application. This study characterizes surgeons' contemporary perceptions and utilization of NOM. STUDY DESIGN/METHODS:A survey addressing NOM was distributed to attending pediatric surgeons through the American Pediatric Surgical Association, the American Academy of Pediatrics Section on Surgery, and the Pediatric Surgery Research Collaborative between 12/2023-6/2024. RESULTS:The survey achieved a response rate of 41.0% (433/1,056). 42.0% reported regularly discussing NOM, but only half of those who discussed NOM did so in a balanced fashion. Fewer regularly offered NOM to eligible patients (27.9%). Common reasons for not offering NOM included the belief that recovery is faster after appendectomy (52.0%) and concern for high recurrence rates (51.5%). Common reasons for offering NOM included the belief that patients appreciate having options (49.2%) and the potential to avoid surgery (48.5%). 71.2% of surgeons considered absence of an appendicolith essential for attempting NOM, while fewer used symptom duration (50.8%), age (36.0%), or WBC (33.3%) when determining NOM eligibility. Therefore, many respondents did not apply the inclusion criteria used in early clinical trials, and when applied, some deviated from them, especially with increased present-day willingness to use NOM in younger patients. CONCLUSIONS:NOM is infrequently discussed with or offered to eligible patients due to limited surgeon buy-in and different valuations of its risks and benefits. However, many surgeons who do offer NOM are comfortable applying it to a broader patient population than initially studied. LEVEL OF EVIDENCE/METHODS:IV.

BACKGROUND:Specialized pediatric surgical referral programs (PSPs) for complex conditions are increasing across the United States, resulting in care rendered geographically distant from patients' homes. We explored care coordination gaps across differing stakeholder perspectives to identify opportunities to optimize post-discharge practices in this evolving landscape. METHODS:We reviewed published literature for guidelines and consensus statements on ideal care coordination practices. Qualitative interviews were conducted with three PSPs examining themes and gaps in their care coordination workflows. Surveys were distributed to an established family support network to assess patient/family perspectives on post-discharge care. To explore communication bias across practice settings, surveys were provided to American Pediatric Surgical Association (APSA) members. RESULTS:Eight thematic domains for an ideal care coordination framework were identified. Effective PSP practices included identifying local physician contacts, providing thorough pre-discharge patient/family education, and ensuring reliable post-discharge PSP access. PSPs reported challenges in ensuring patient access to medication/devices, variability in discharge documentation, and lack of closed-loop feedback. Fifty-two family support network surveys (13% response) revealed PSPs frequently fulfilled medication/device safety, but demonstrated gaps in medication/device receipt confirmation, insurance coverage for medications/devices, and assessment of discharge readiness. In 239 APSA responses (17% response), local surgeons perceived bias against non-academic practice environments as a barrier to effective post-discharge PSP care coordination. CONCLUSION/CONCLUSIONS:PSPs implement care coordination practices that inconsistently address the core domains of a standardized framework. These findings provide guidance for improved alignment between PSPs, families, and local surgeons to optimize pediatric surgical post-discharge care coordination independent of geography.

INTRODUCTION/BACKGROUND:GLP-1 receptor agonists (GLP1-RAs) are increasingly prescribed as an alternative to bariatric surgery for weight loss, and may pose as an alternative to conversion Roux-En-Y Gastric Bypass (cRYGB) in patients with insufficient weight loss or weight recurrence after sleeve gastrectomy [A C, N C, A I. Postoperative morbidity and weight loss after revisional bariatric surgery for primary failed restrictive procedure: a systematic review and network meta-analysis. International Journal of Surgery; 2022;Jensen et al. in Obes Surg 33:1017-1025, 2023; Jamal et al. in Obes Surg 34:1324-1332, 2024; Lautenbach A, Wernecke M, Stoll FD, Meyhöfer SM, Meyhöfer S, Aberel J. 1422-P: The potential of semaglutide once-weekly in patients without Type 2 Diabetes with weight regain or insufficient weight loss after bariatric surgery. Diabetes 2022; 71(Supplement_1);]. METHODS AND PROCEDURES/METHODS:Adult patients ≥ 18 years old, who previously underwent a sleeve gastrectomy and were subsequently treated with weekly injectable Semaglutide or Tirzepatide, or treated with conversion from sleeve gastrectomy were included for analysis. Patients converted for GERD, GLP1-RA use with BMI ≤ 35, or pre operative GLP1-RA use were excluded. Post operative weights and Hgb A1C were assessed from 3 months to 3 years post intervention (start of GLP1-RA or surgery). T-test, ANOVA, and chi-squared analysis were used to compare groups, while multivariable linear regression analysis was used to evaluate the effect of bariatric surgery on %TBWL at 3 years post intervention when adjusting for baseline characteristics. RESULTS:4901 patients were included for analysis (3004 cRYGB, 1897 GLP1-RA). There was no difference in pre-intervention weight (242.8 ± 44.4 GLP1-RA vs 242.3 ± 57.8 cRYGB, p = .993). cRYGB patients had a higher baseline Hgba1c (6.19 ± 1.4 vs 5.85 ± 1.2, p < 0.001). cRYGB was associated with significantly greater weight loss at all post operative time points up to 3 years post intervention, (26.1 vs 13.7%, p < 0.001). There was no significant difference in Hgba1c control between treatments at all post intervention time points (all p > 0.05). In the multivariate linear regression analysis, when adjusting for sex, baseline BMI, baseline age, and non-white race, cRYGB was associated with an 11% greater %TBWL compared to those who were treated with a GLP1-RA. CONCLUSIONS:For patients who have had insufficient weight loss or weight recurrence following sleeve gastrectomy, conversion to RYGB offers greater, long-term weight loss compared to GLP1-RAs.

BACKGROUND AND OBJECTIVES/OBJECTIVE:Diagnosis of adnexal torsion is challenging due to variable clinical presentations and often inconclusive imaging results. We hypothesized that diagnostic delays are common, leading to prolonged ischemia and subsequent tissue loss. We aimed to identify factors associated with diagnostic delays in pediatric patients with adnexal torsion. METHODS:We performed a multi-institutional retrospective review of females aged 5 to 18 years with confirmed adnexal torsion between 2013 to 2022. Delay to care was defined as prior emergency department discharge within 7 days of operation and/or hospital admission without initial plan for operation. RESULTS:862 patients were identified from 10 children's hospitals, with delayed diagnosis in 30%. Patients with delay were less likely to present with emesis or fever, have initial pediatric surgery consultation, or have typical ultrasound findings of torsion compared to those without delay (P < .05). For every unit increase in area deprivation index, the odds of delay increased by 1.3% (odds ratio 1.013, 95% CI, 1.007-1.018). The odds of delay were 81% greater for patients living > 30 miles from the hospital compared with 1-10 miles (odds ratio 1.812, 95% CI, 1.236-2.657). Oophorectomy and salpingectomy rates were 10% and 13%; those with delay had higher risk of oophorectomy (14% vs 7%, P = .002). CONCLUSION/CONCLUSIONS:Delayed diagnosis of adnexal torsion is common and associated with higher area deprivation index and farther distance from hospital. Risk of oophorectomy was higher in patients with delay. Improved diagnostics and increased awareness of social disparities are critical to decrease time to definitive treatment and improve rates of adnexal salvage.

INTRODUCTION/BACKGROUND:Ergonomic injuries pose significant risks to surgeons, affecting health, productivity, care access, and retirement age. Despite unique challenges in pediatric surgery, including varied patient sizes and operations, little is known about pediatric surgeons' ergonomics. This study aimed to assess ergonomic practices and associated injuries among pediatric surgeons. METHODS:A cross-sectional survey was distributed to the American Pediatric Surgical Association regular members and fellows. Data collected included demographics, physical health, surgical practices, operating habits, discomfort, injuries, interventions, and outcomes. Associations with injury were analyzed using Fisher's exact test, Pearson's Chi-squared test, and Wilcoxon rank-sum tests. RESULTS:One hundred seventeen (11%) surgeons responded, 53% were male with a median of 15 y in practice (interquartile range: 6-25). Regarding operating habits, 76% did not take regular breaks, 48% double-gloved, and 51% used loupes regularly. Notably, 90% experienced discomfort or pain, and 30% sustained injuries from operating, primarily affecting the neck and cervical spine (53%). White-identifying pediatric surgeons (80%) reported significantly more ergonomic injuries than other races (P < 0.01). Only 18% of respondents received ergonomic training. Ergonomics training and operating with a resident or co-surgeon were associated with less injury (P < 0.05). Among those experiencing discomfort or injury, 13% underwent a procedure, 63% experienced sleep disturbance, 74% reported contribution to burnout, and 88% used pain medications. CONCLUSIONS:Ergonomic-related discomfort and injuries occurred in nearly 90% of pediatric surgeons who responded. Few had ergonomic training and most reported an impact on well-being. Modifiable ergonomic factors for pediatric surgeons, along with targeted interventions to reduce injuries, can improve surgeon well-being.

BACKGROUND:Four-dimensional computed tomography is routinely used to localize parathyroid disease, with consistently excellent parathyroid gland localization rates reported. This study evaluated whether pairing 4-dimensional computed tomography results with preoperative clinical variables can accurately predict single-gland disease in primary hyperparathyroidism. METHODS:Patients with primary hyperparathyroidism who underwent both 4-dimensional computed tomography imaging and parathyroidectomy between January 2019 and September 2021 at a large academic health system were included. Patient demographics, preoperative characteristics, and peri- and postoperative data were collected. The accuracy of 4-dimensional computed tomography in correctly identifying patients with single-gland disease with and without preoperative calcium and parathyroid hormone levels was calculated. Single-gland disease was defined by intraoperative parathyroid hormone decrease >50% and a hypercellular gland on pathology. RESULTS:One hundred seventy-five patients had 4-dimensional computed tomography results suggestive of single gland disease. One hundred fifty-two patients (87%) were predicted correctly to have single-gland disease. The predictive accuracy increased when stratifying by preoperative calcium (≥10.5 mg/dL, ≥11 mg/dL, and ≥12 mg/dL) and parathyroid hormone levels (≥65 pg/mL, ≥100 pg/mL, and ≥200 pg/dL). The accuracy further increased when stratifying by age (≤50 years). Accuracy for single gland disease was 100% when combined with any of the following: (1) calcium ≥12 mg/dL, (2) parathyroid hormone ≥200 pg/dL, or (3) calcium ≥11 mg/dL in patients ≤50 years. CONCLUSION/CONCLUSIONS:Four-dimensional computed tomography alone accurately predicted single gland disease in 87% of patients with primary hyperparathyroidism. When combined with preoperative calcium, parathyroid hormone and age thresholds, predictive accuracy for single-gland disease approached 100%. Given the high likelihood of single-gland disease in these scenarios, clinicians may consider offering focused unilateral parathyroidectomy without intraoperative parathyroid hormone monitoring in selected patients.
