Modern surgical strategies in pediatric neuroblastoma: Evolving approaches and treatment principles.

Neuroblastoma, the most common extracranial solid tumor in children under the age of 5, has been described as early as the 19th century, and its complexity has continued to intrigue researchers, as well as medical and surgical specialists. At one end of the phenotypic spectrum, neuroblastoma is self-limiting with minimal to no intervention required, while on the opposite end exists the challenge of refractory disease despite aggressive management and toxic systemic treatments. The goal of this review is to describe a comprehensive surgical perspective and contemporary approach to neuroblastoma.

The Only Constant is Change: A Longitudinal Analysis of Women's Representation Across American Pediatric Surgical Association (APSA) Committee Leadership.

BACKGROUND: Women have historically been underrepresented in surgical leadership and in specialty organizations. This study longitudinally examines representation of women across committee leadership within the American Pediatric Surgical Association (APSA). METHODS: Annual APSA committee chair and vice-chair rosters (2003-2023) were obtained. If not self-reported in the membership roster, gender was classified based upon review of publicly available data. Proportions of women who served as chairs and vice-chairs were quantified by committee and by year. RESULTS: Overall, the proportion of women serving as APSA committee chairs and vice-chairs increased from 11% to 48% during the study period (p = 0.001). In examining each position, the proportion of women chairs increased from 12% to 40% (p = 0.042), while women vice-chairs increased from 10% to 58% (p = 0.009). The committees with the highest cumulative proportion of women chairs were Benjy Brooks (100%), Diversity Equity & Inclusion (100%), Finance (100%), Global Pediatric Surgery (67%), and Wellness (67%). Four committees- Trauma, Access to Surgery for Kids, Practice, and Professional Development - were not led by a woman chair in the entire study period. Additionally, five committees that traditionally have had significant impact on organizational workflow and agendas all had cumulative proportions of women chairs of less than 50% - Education (33%), Publications (28.6%), Outcomes (19%), Surgical Quality & Safety (18.8%) and Program (9.5%). CONCLUSION: These results demonstrate encouraging trends in the gender diversity of APSA leadership. However, this progress does not appear to be evenly distributed; leadership of key committees continues to lack substantial women's representation. LEVEL OF EVIDENCE: III.

Serious Illness Communication Training for Surgical Critical Care Fellows: A Pilot Implementation Study.

OBJECTIVE: Effective communication about serious illness is pivotal in delivering surgical palliative care-a crucial component of comprehensive surgical critical care (SCC). However, limited educational strategies exist for fellow-level trainees, who are often directing clinical decision-making and building mutual trust with patients and families. This pilot study assess implications of a novel serious illness communication training opportunity tailored specifically for SCC fellows. DESIGN: Prospective implementation of a multimodal training session (1 hour-didactic lecture, 2 hours-live-action simulation), using pre- and postcourse surveys to assess self-perceived confidence. SETTING: University of Michigan in Ann Arbor, Michigan. PARTICIPANTS: Eleven ACGME-accredited SCC fellows during the 2023 to 2024 academic year participated and completed all 3 survey assessments. RESULTS: Following the course, 6 of 7 confidence domains showed improvement, with 2 reaching statistical significance-communication skills to discuss goals of care and/or code status (3.73 vs. 4.36, p = 0.018) and end-of-life care or transition to comfort-focused care (3.36 vs. 4.18, p = 0.023) with a patient or family member. At 6-month follow up, fellows reported further increases in all queried domains, though changes were nonsignificant. Greatest absolute increases were noted in delivering serious news (4.18 vs. 4.55, p = 0.143) and expressing nonverbal empathy (4.09 vs. 4.50, p = 0.197). The majority (91%) of respondents felt more comfortable having serious illness conversations with patients and families due to their training course experience. CONCLUSION: Implementation of a 3-hour training course tailored for SCC fellows significantly boosted both the immediate and long-term confidence in their serious illness communication skills and ability to manage complex care scenarios.

Patterns and Outcomes of Epoprostenol Use in Infants with Congenital Diaphragmatic Hernia Requiring Extracorporeal Life Support.

OBJECTIVE: To describe our experience utilizing epoprostenol for pulmonary hypertension (PH) in infants with congenital diaphragmatic hernia (CDH) requiring extracorporeal life support (ECLS). STUDY DESIGN: We retrospectively reviewed infants diagnosed with CDH who required ECLS at our institution from 2013 to 2023. Data collected included demographics, disease characteristics, medication administration patterns, and hospital outcomes. We first compared infants who received intravenous epoprostenol and those who did not. Among infants who received epoprostenol, we compared survivors and nonsurvivors. χ² test/Fisher's exact and Mann-Whitney tests were used, with significance defined at P < .05. RESULTS: Fifty-seven infants were included; 40 (70.2%) received epoprostenol. Infants receiving epoprostenol had lower observed/expected total fetal lung volume (O/E TFLV) on magnetic resonance imaging (20 vs 26.2%, P = .042) as well as higher prenatal frequency of liver-up (90 vs 64.7%, P = .023) and "severe" classification (67.5 vs 35.3%, P = .007). Survival with and without epoprostenol was comparable (60% vs 64%, P = .23). Of those receiving epoprostenol, both survivors and nonsurvivors had similar prenatal indicators of disease severity. Most (80%) of hernia defects were classified as type C/D and 68% were repaired <72 hours after ECLS cannulation. The median age at initiation of epoprostenol was day of life 6 (IQR: 4, 7) in survivors and 8 (IQR: 7, 16) in nonsurvivors (P = .012). Survivors had shorter ECLS duration (11 vs 20 days, P = .049). Of nonsurvivors, refractory PH was the cause of death for 13 infants (81%). CONCLUSIONS: In infants with CDH requiring ECLS, addition of epoprostenol appears promising and earlier initiation may affect survival.

A modern approach to multiple pulmonary resections in children with recurrent metastatic pulmonary disease.

Implications of repeated resections of pulmonary metastasis (PM) are not well documented in the modern era. Fifteen children underwent two (n = 8), three (n = 3), or four or more (n = 3) resections (total = 38 procedures), most commonly for osteosarcoma (71%). Operative approach included muscle-sparing thoracotomy (71%), non-muscle-sparing thoracotomy (18%), and video-assisted thoracoscopy (11%). Median resected nodules per procedure was four (range = 1-95). Prolonged air leaks were the most common postoperative complication (29%). Median hospital stay was 4 days, and no children were discharged with or have required oxygen. Event-free survival is 67% at median follow-up time of 54 months, with an overall survival rate of 64%. Repeat resection of PM appears to be well tolerated, without prolonged hospital stays or compromised pulmonary function.

Safety and feasibility of conversion from venoarterial to venovenous extracorporeal membrane oxygenation in pediatric patients: A case series.

INTRODUCTION: In children requiring venoarterial (VA) extracorporeal membrane oxygenation (ECMO) for long durations, conversion to venovenous (VV) support may be advantageous. The purpose of this study was to evaluate the feasibility and safety of conversion from VA to VV ECMO. METHODS: This is a retrospective review of all children who underwent conversion from VA to VV ECMO at a single institution, from 2015 to 2022. Indications for and methods of conversion were examined as well as adverse events including re-operation, ischemic complications, renal failure, and mortality. RESULTS: Of 422 pediatric patients on initial VA ECMO, 4 children (0.9%) underwent conversion from VA to VV support. The indications for cannulation were: respiratory failure due to COVID19, respiratory failure due to congenital diaphragmatic hernia, cardiac dysfunction following heart transplant, and sepsis with associated left ventricular dysfunction. The indications for conversion were bleeding from the arterial cannula and ongoing respiratory failure. The median time to conversion was 6.5 days (range 4-54 days) and the median length of ECMO run was 34.5 days. Three patients required renal replacement therapy with two progressing to long-term dialysis. There were no ischemic limb complications although one patient developed a femoral artery pseudoaneurysm that required re-operation. Three patients survived to discharge. One patient was unable to be decannulated after conversion and mechanical support was withdrawn. CONCLUSIONS: Conversion to VV ECMO from initial VA ECMO cannulation is feasible but a rare event. For patients with cardiac stability but continued need for respiratory support, conversion to VV ECMO can be considered.

Diverticulosis and Diverticulitis on YouTube: Is Popular Information the Most Reliable?

Background Patients utilize online health information to inform their medical decision-making. YouTube is one of the most popular media platforms with abundant health-related resources, yet the quality of the disseminated information remains unclear. This study aims to evaluate the quality and reliability of content pertaining to diverticulosis and diverticulitis on YouTube. Methods One author queried the terms "diverticulosis," "diverticulitis," "acute diverticulitis," and "chronic diverticulitis" on YouTube. The first 50 videos per search were selected for analysis. Duplicates, non-English videos, or procedural content were excluded. Video characteristics including view count, likes, comments, duration, days since upload, view ratio, video power index, and video sources (professional organizations (POs), health information websites (HIWs), and entertainment/independent users (EIUs)) were collected. Videos were scored using the mDISCERN and Global Quality Score (GQS). Results Sixty-four videos were included. DISCERN scores significantly differed between POs (n=20, mean=4.35), HIWs (n=29, mean=2.97), and EIUs (n=15, mean=1.83). GQS also significantly differed between POs (n=20, mean=4.47), HIWs (n=29, mean=3.62), and EIUs (n=15, mean=2.5). Video characteristics significantly differed between groups, with most user engagement seen in EIUs. Conclusion POs and HIWs disseminate higher quality health information about diverticular disease on YouTube. The higher viewer engagement with EIUs is concerning, as these sources were found to have lower quality content. Although YouTube has the capability to provide valuable information on diverticulosis and diverticulitis, enhanced content screening is needed to ensure accuracy and validation.

University surgeons: An ideal community for unity amid national discourse.

The current sociopolitical landscape continues to infiltrate our house of surgery, leaving faculty, staff, and learners challenged by uncertainty while introducing downstream interference to cohesive health care delivery for our patients. National surgical associations must cultivate an ethos of unity and intellectual solidarity within the surgical community, thereby reinforcing a foundation for productive and respectful discourse. This is not a call for uniformity in thought but for unity in purpose, action, and mutual respect.

Mandibular Distraction in Dual Syndromic Diagnosis.

Mandibular distraction has variable outcomes in Treacher-Collins syndrome. Dual syndromic diagnosis is a rare occurrence that complicates management. Here, the authors present a patient with Treacher-Collins syndrome and severe retrognathia requiring tracheostomy who failed repeat mandibular distraction and decannulation. A genetic workup later revealed Angelman syndrome with severe developmental delay. We discuss explanations for difficulties encountered during mandibular distraction as well as surgical options for patients with Treacher-Collins who fail multiple attempts at decannulation. Overall, patients with dual diagnoses can exhibit an underlying problem in bone formation and mineralization, which challenges any attempt at craniofacial manipulation.

Health Disparities Research: What Every Pediatric Surgeon Should Know.

While the earliest published health disparity research in the United States dates to 1899, the field was not formally established until the late 20th century. Initially focused on race and ethnicity, the field has broadened to include socioeconomic status. Several measures have been developed to quantify socioeconomic disadvantage, including the Social Vulnerability Index, Area Deprivation Index, and Child Opportunity Index. These indices have been validated and demonstrate correlation with health outcomes. However, socioeconomic status cannot fully explain health inequities experienced by people of minoritized racial and ethnic identities. Three generations of health disparities research have been described-identification of disparities, root analysis, and development of interventions to mitigate health inequities. While there has been an increase in publication of health disparity research, there is little third generation work. It is imperative that health disparities research move beyond defining the problem and toward interventions that will reduce health inequities. LEVELS OF EVIDENCE: Level IV.

Periprosthetic hip infection: Current concepts and the Wrightington experience.

Total hip arthroplasty (THA) is a highly successful operation performed worldwide in increasing numbers for a wide range of indications. There has been a corresponding rise in the incidence of periprosthetic joint infection of the hip (PJIH), which is a devastating complication. There is a significant variation in the definition, diagnosis and management of PJIH largely due to a lack of high-level evidence. The current standard of practice is largely based on cohort studies from high-volume centres, consensus publications amongst subject experts, and national guidance. This review describes our philosophy and practical approach of managing PJIH at a regional tertiary high-volume joint replacement centre.

Is There Still a Role for Peritoneal Drains in Neonatal Pneumoperitoneum? A Single-Center Experience.

INTRODUCTION: Although pneumoperitoneum from necrotizing enterocolitis or spontaneous intestinal perforation is a surgical emergency, risk stratification to determine which neonates benefit from initial peritoneal drainage (PD) is lacking. METHODS: Using a single-center retrospective review of very low birth weight neonates under 1500 g who underwent PD for pneumoperitoneum (January 2015 to December 2023) from necrotizing enterocolitis or spontaneous intestinal perforation, two cohorts were created: drain "responders" (patients managed definitively with PD; includes placement of a second drain) and "nonresponders" (patients who underwent subsequent laparotomy or died after PD). Antenatal/postnatal characteristics, periprocedural clinical data, and hospital outcomes were compared between responders and nonresponders using Student's t-test, chi-squared test, or Kruskal-Wallis test as appropriate, with P < 0.05 considered significant. RESULTS: Fifty-six neonates were included: 31 (55%) drain responders and 25 (45%) nonresponders. Birth weight, gestational age, sex, ethnicity, use of postnatal steroids, and enteral feeds were similar between the cohorts. Nonresponders had higher base deficits (-3.4 versus -5.0, P = 0.032) and FiO2 (0.25 versus 0.52, P = 0.001) after drain placement. Drain responders had significantly shorter lengths of stay (89 versus 148 days, P = 0.014) and lower mortality (6.4% versus 56%, P < 0.001). A subgroup analysis of the nonresponders showed no differences in birth weight, vasopressor requirement, FiO2, or postdrain base deficit between nonresponders who had a drain alone versus laparotomy following drain placement. CONCLUSIONS: PD remains a viable initial therapy for pneumoperitoneum in premature very low birth weight neonates (< 1500 g), demonstrating clinical response in more than half. Ongoing clinical assessment and judgment is imperative after drain placement to ensure continued clinical improvement.

Pediatric surgical border health: Supply may not be meeting demand in South Texas communities.

INTRODUCTION: The Rio Grande Valley (RGV) has historically high incidence of congenital defects (CDs) necessitating intervention by pediatric surgical specialties. We examined mortality in this region and related workforce patterns. METHODS: Mortality data related to CDs (2007-2021) and surgical workforce trends/projections (2024-2032) were collected using multiple databases: National Vital Statistics System, Texas Department of State Health Services, Texas Medical Board, Center for Disease Control. RESULTS: Nationally, RGV counties rank as high as 5th in CD mortality rates. Between 2020 and 2024, 3 of 4 studied pediatric surgical specialties experienced stagnant/decreasing workforces ranging from 0 to 66 â€‹%. Furthermore, the RGV is projected to have some of the most marked state-wide disparities in surgical providers over the next 8 years. CONCLUSION: High infant mortality rates along with ongoing and future shortages of surgical specialists is concerning. These results may inform allocation of public health resources and workforce distribution to improve outcomes.

Current advances in the use of artificial intelligence in predicting and managing urological complications.

BACKGROUND: Artificial intelligence (AI) has emerged as a promising avenue for improving patient care and surgical outcomes in urological surgery. However, the extent of AI's impact in predicting and managing complications is not fully elucidated. OBJECTIVES: We review the application of AI to foresee and manage complications in urological surgery, assess its efficacy, and discuss challenges to its use. METHODS AND MATERIALS: A targeted non-systematic literature search was conducted using the PubMed and Google Scholar databases to identify studies on AI in urological surgery and its complications. Evidence from the studies was synthesised. RESULTS: Incorporating AI into various facets of urological surgery has shown promising advancements. From preoperative planning to intraoperative guidance, AI is revolutionising the field, demonstrating remarkable proficiency in tasks such as image analysis, decision-making support, and complication prediction. Studies show that AI programmes are highly accurate, increase surgical precision and efficiency, and reduce complications. However, implementation challenges exist in AI errors, human errors, and ethical issues. CONCLUSION: AI has great potential in predicting and managing surgical complications of urological surgery. Advancements have been made, but challenges and ethical considerations must be addressed before widespread AI implementation.

Optimizing Readability of Patient-Facing Hand Surgery Education Materials Using Chat Generative Pretrained Transformer 3.5.

PURPOSE: To address patient health literacy, the American Medical Association and the National Institutes of Health recommend that readability of patient education materials should not exceed an eighth grade reading level. However, patient-facing materials often remain above the recommended average reading level. Current online calculators provide readability scores; however, they lack the ability to provide text-specific feedback, which may streamline the process of simplifying patient materials. The purpose of this study was to evaluate Chat Generative Pretrained Transformer (ChatGPT) 3.5 as a tool for optimizing patient-facing hand surgery education materials through reading level analysis and simplification. METHODS: The readability of 18 patient-facing hand surgery education materials was compared by a traditional online calculator for reading level and ChatGPT 3.5. The original excerpts were then entered into ChatGPT 3.5 and simplified by the artificial intelligence tool. The simplified excerpts were scored by the same calculators. RESULTS: The readability scores for the original excerpts from the online calculator and ChatGPT 3.5 were similar. The simplified excerpts' scores were lower than the originals, with a mean of 7.28, less than the maximum recommended 8. CONCLUSIONS: The use of ChatGPT 3.5 for the purpose of simplification and readability analysis of patient-facing hand surgery materials is efficient and may help facilitate the conveyance of important health information. ChatGPT 3.5 rendered readability scores comparable with traditional readability calculators, in addition to excerpt-specific feedback. It was also able to simplify materials to the recommended grade levels. CLINICAL RELEVANCE: By confirming ChatGPT3.5's ability to assess and simplify patient education materials, this study offers a practical solution for potentially improving patient comprehension, engagement, and health outcomes in clinical settings.

Approach to Constipation in Children: Recommendations for Evaluation and Management.

Constipation is common in childhood, and most patients can be successfully managed by their primary care provider. However, some patients will require more specialized management either due to an underlying congenital colorectal disorder such as Hirschsprung disease or anorectal malformation or due to severe functional constipation that is refractory to medical management.

Standardization of Weightage Assigned to Different Segments of the Hand X-ray for Assessment of Bone Age by the Greulich-Pyle Method.

Introduction: Bone age (BA) assessment is important in evaluating disorders of growth and puberty; the Greulich and Pyle atlas method (GP) is most used. We aimed to determine the weightage to be attributed by raters to various segments of the hand x-ray, namely, distal end of radius-ulna (RU), carpals, and short bones for rating bone age using the GP atlas method. Methods: 692 deidentified x-rays from a previous study (PUNE-dataset) and 400 from the Radiological Society of North America (RSNA-dataset) were included in the study. Mean of BA assessed by experienced raters was termed reference rating. Linear regression was used to model reference age as function of age ratings of the three segments. The root-mean-square-error (RMSE) of segmental arithmetic mean and weighted mean with respect to reference rating were computed for both datasets. Results: Short bones were assigned the highest weightage. Carpals were assigned higher weightage in pre-pubertal PUNE participants as compared to RSNA, vice-versa in RU segment of post-pubertal participants. The RMSE of weighted mean ratings was significantly lower than for the arithmetic mean in the PUNE dataset. Conclusion: We thus determined weightage to be attributed by raters to segments of the hand x-ray for assessment of bone age by the GP method.

Early Lessons From Implementation of Holistic Review for Pediatric Surgery Fellowship Applicants.

PURPOSE: Holistic review (HR) considers applicants' unique identities and experiences rather than focusing on academic metrics. Though several residency programs have demonstrated increases in women and those underrepresented in medicine (URiM), this is the first study to examine HR in pediatric surgery (PS). METHODS: Using a retrospective review of applicants, demographic, academic, and non-academic metrics of traditional review (TR) [2015-2017] were compared to HR [2018-2022]. HR initiatives include expansion of faculty reviewers, implementation of a pre-screening rubric, and greater prioritization of non-academic factors. Chi-squared/Fisher's exact tests, Wilcoxon rank-sum tests, and two sample z-test for proportions were used where appropriate. RESULTS: For 635 applicants (TR: 268, HR: 367), the proportion offered interviews in the TR and HR cohorts were similar (31.7 vs 36%, p = 0.30). Candidates selected for interview pre- and post-HR most commonly graduated from residency programs affiliated with PS fellowships (56.5 vs 50%, p = 0.65). After HR implementation, no change in proportion of women interviewees (TR: 52.9 vs HR: 54.5%, p = 0.93) was observed. Though URiM residents applying to PS remained consistently low (TR: 14.6 vs HR: 10.9%, p = 0.21), significantly more received interviews with HR (30.8 vs 42.5%, p = 0.001). The median number of peer-review publications per interviewee increased (17 vs 22, p = 0.02) as did non-academic achievements (leadership, service, athletic awards, etc.) per applicant (1.0 vs 1.5, p = 0.104), though the latter did not reach significance, demonstrating similar qualification of interviewees in HR and TR. CONCLUSION: Holistic review of PS fellowship applications increased the proportion of URiM interviewees, despite a persistently low URiM proportion in the applicant pool. Furthermore, implementing HR did not sacrifice the caliber of interviewees, as publications and non-academic achievements increased by over 25% in the HR cohort. LEVEL OF EVIDENCE: IV.
