Subspecialization in pediatric surgery: Results of a survey to the American Pediatric Surgical Association

Management and Outcomes of Wilms Tumor With Suprarenal Intravascular Extension: A Pediatric Surgical Oncology Research Collaborative Study

OBJECTIVE

The purpose of this study was to describe management and outcomes from a contemporary cohort of children with Wilms tumor complicated by inferior vena caval thrombus.

BACKGROUND

The largest series of these patients was published almost 2 decades ago. Since then, neoadjuvant chemotherapy has been commonly used to manage these patients, and outcomes have not been reported.

METHODS

Retrospective review of 19 North American centers between 2009 and 2019. Patient and disease characteristics, management, and outcomes were investigated and analyzed.

RESULTS

Of 124 patients, 81% had favorable histology (FH), and 52% were stage IV. IVC thrombus level was infrahepatic in 53 (43%), intrahepatic in 32 (26%), suprahepatic in 14 (11%), and cardiac in 24 (19%). Neoadjuvant chemotherapy using a 3-drug regimen was administered in 82% and postresection radiation in 90%. Thrombus level regression was 45% overall, with suprahepatic level showing the best response (62%). Cardiopulmonary bypass (CPB) was potentially avoided in 67%. The perioperative complication rate was significantly lower after neoadjuvant chemotherapy [(25%) vs upfront surgery (55%); P =0.005]. CPB was not associated with higher complications [CPB (50%) vs no CPB (27%); P =0.08]. Two-year event-free survival was 93% and overall survival was 96%, higher in FH cases (FH 98% vs unfavorable histology/anaplastic 82%; P =0.73). Neither incomplete resection nor viable thrombus cells affected event-free survival or overall survival.

CONCLUSIONS

Multimodal therapy resulted in excellent outcomes, even with advanced-stage disease and cardiac extension. Neoadjuvant chemotherapy decreased the need for CPB to facilitate resection. Complete thrombectomy may not always be necessary.

Practice Patterns in the Operative Management of Pediatric Thyroid Disease Across Surgical Specializations

BACKGROUND

Multiple surgical specializations are involved in the operative management of pediatric thyroid disease, but current practice patterns remain unknown. The objective of this study was to examine current practice patterns in the operative management of pediatric thyroid disease, specifically comparing practices across different surgical specializations including pediatric surgery, pediatric otolaryngology, general surgery, adult otolaryngology, and endocrine-focused general surgery.

METHODS

Children 0-18 years-old undergoing thyroid surgery from 2015 to 2019 were identified using the Healthcare Cost and Utilization Project State Inpatient Databases and State Ambulatory Surgery and Services Databases across 6 states. Surgeon specialization was determined for all included surgeons. Patient and hospital characteristics were compared across surgical specializations. Clinical outcomes including hypocalcemia/hypoparathyroidism, recurrent laryngeal nerve injury, hematoma, and wound infection were assessed.

RESULTS

A total of 1241 pediatric thyroidectomies performed by 363 surgeons were included. Procedures were most frequently performed by pediatric surgeons (34.9%). Only 7.2% of procedures were performed by adult general surgeons. There were statistically significant differences in patient age, sociodemographics, surgical indications, and type of procedure performed between specializations (p < 0.05). Endocrine-focused general surgeons had the highest average annual thyroid procedure volume with 78.2 cases/year, and pediatric surgeons and pediatric otolaryngologists had the lowest volumes with 0.7 and 0.6 cases/year, respectively. Overall complication rates were low.

CONCLUSIONS

Operative management of pediatric thyroid disease was most frequently performed by pediatric surgery. Pediatric specializations are more likely to operate on low-income, minority children with public insurance and patients with Graves' disease. Overall complications were low.

Gender Distribution and Trends of Ophthalmology Subspecialties, 1992-2020

PURPOSE

To describe the gender trends in ophthalmology primary practice areas using the American Board of Ophthalmology (ABO) diplomates.

DESIGN

A trend study plus a cross-sectional study of the ABO's database.

METHODS

The de-identified records of all (N = 12,844) ABO-certified ophthalmologists between 1992 and 2020 were obtained. The year of certification, gender, and self-reported primary practice for each ophthalmologist was recorded. Subspecialty was defined as the self-reported primary practice emphasis. Practice trends of the entire population and the subpopulation of subspecialists were explored based on gender and were then visualized using tables and graphs and analyzed using the χ2 or Fisher exact test.

RESULTS

A total of 12,844 board-certified ophthalmologists were included. Nearly half (47%) reported a subspecialty as their primary practice area (n = 6042), of whom the majority were male (65%, n = 3940). In the first decade, men outnumbered women reporting subspecialty practices by more than 2:1. Over time, the number of women subspecialists increased whereas the number of men remained stable, such that by 2020 women comprised almost half of new ABO diplomates reporting subspecialty practice. When all subspecialists were compared within gender, there was not a significant difference (P = .15) between the percentage of male (46%) and female (48%) ophthalmologist reporting a subspecialty practice. However, a significantly greater proportion of women than men reported primary practice in pediatrics (20.1% vs 7.9%, P < .001) and glaucoma (21.8% vs 16.0%, P < .0001). Alternatively, a significantly greater proportion of men reported primary practice in vitreoretinal surgery (47.2% vs 22.0%, P < .0001). There was no significant difference between the proportion of men and women reporting cornea (P = .15) or oculoplastics (P = .31).

CONCLUSIONS

The number of women in ophthalmology subspecialty practice has increased steadily over the past 30 years. Men and women subspecialize at the same rate, but significant differences exist between the types of ophthalmology practiced by each gender.

Evaluation of the regional distribution of the pediatric surgery workforce and surgical load in Brazil

Objective

The purpose of this study is to examine the regional distribution of the pediatric surgery workforce and the expected local demand for pediatric surgical procedures in Brazil.

Methods

We collected data on the pediatric surgical workforce, surgical volume, Gross Domestic Product per capita, and mortality for gastrointestinal tract malformations (MGITM) across the different regions of Brazil for 2019.

Results

Data from the Federal Medical Council reported 1515 pediatric surgery registries in Brazil, corresponding to 1414 pediatric surgeons (some pediatric surgeons are registered in more than one state), or 2.4 pediatric surgeons per 100 000 children 14 years of age and younger. There were 828 men and 586 women. The mean age was 51.5±12.8 years, and the mean time from graduation was 3.4±5.7 years. There is a higher concentration of pediatric surgeons in the wealthier Central-West, South, and Southeast regions. Individual surgical volume ranged from 88 to 245 operations/year (average 146 operations/year) depending on the region. Of these, only nine (6.1%) were high-complexity (including neonatal) operations. MGITM tended to be higher in the poorer North and Northeast regions than in other regions of Brazil.

Conclusions

Our findings suggest significant disparities in the surgical workforce and workload across Brazil related to socioeconomic status. Regions with an increased surgical workforce were associated with lower MGITM. The average number of complex operations performed annually by each pediatric surgeon was considerably low. Strategic investment and well-defined health policies are imperative to enhance the quality of surgical care in the different regions of Brazil.

Pediatric Liver and Transplant Surgery: Results of an International Survey and Expert Consensus Recommendations

BACKGROUND

Pediatric liver surgery is a complex and challenging procedure and can be associated with major complications, including mortality. Best practices are not established. The aims of this study were to evaluate surgeons' individual and institutional practices in pediatric liver surgery and make recommendations applicable to the management of children who require liver surgery.

METHODS

A web-based survey was developed, focusing on the surgical management of children with liver conditions. It was distributed to 34 pediatric surgery faculty members of the Biliary Atresia and Related Disorders (BARD) consortium and 28 centers of the European Reference Network-Rare Liver. Using the Delphi method, a series of questions was then created to develop ideas about potential future developments in pediatric liver surgery.

RESULTS

The overall survey response rate was 70.6% (24/34), while the response rate for the Delphi questionnaire was 26.5% (9/34). In centers performing pediatric liver surgery, most pediatric subspecialties were present, although pediatric oncology was the least present (79.2%). Nearly all participants surveyed agreed that basic and advanced imaging modalities (including ERCP) should be available in those centers. Most pediatric liver surgeries were performed by pediatric surgeons (69.6%). A majority of participants agreed that centers treating pediatric liver tumors should include a pediatric transplant program (86%) able to perform technical variant grafts and living donor liver transplantation. Fifty-six percent of responders believe pediatric liver transplantation should be performed by specialized pediatric surgeons.

CONCLUSION

Pediatric liver surgery should be performed by specialized pediatric surgeons and should be centralized in regional centers of excellence where all pediatric subspecialists are present. Pediatric hepatobiliary and transplant training needs to be better promoted amongst pediatric surgery fellows to increase this subspecialized workforce.

Bariatric surgery practice patterns among pediatric surgeons in the United States

BACKGROUND

Metabolic and bariatric surgery (MBS) in adolescents has been shown to be safe and effective, but current practice patterns are variable and poorly understood. The aim of this study is to assess current MBS practice patterns among pediatric surgeons in the United States.

METHODS

American Pediatric Surgical Association members were surveyed on current bariatric surgery practices.

RESULTS

Four hundred and three (40%) surgeons out of a total of 1013 pediatric surgeons responded to the survey. Only 2 respondents had additional training in MBS (0.5%). One hundred thirty-two (32.6%) report that their practice participates in metabolic and bariatric surgery, with 123 (30.4%) having a specific partner specializing in MBS. Most respondents (92%) stated that they believe high volume is associated with better outcomes with regard to MBS. Only 17 (4.2%) surgeons performed a metabolic and bariatric surgery in the last year. All routinely perform sleeve gastrectomy as their primary procedure. Most (82%) perform procedures with an additional surgeon, either another pediatric surgeon (47%) or an adult bariatric surgeon (47%). All pediatric bariatric surgeons responded that they believe high volume led to better outcomes. Adolescent MBS programs most commonly included pediatric nutritionists (94%), pediatric psychologists (94%), clinical nurses (71%), clinical coordinators (59%), pediatric endocrinologists (59%), and exercise physiologists (52%).

CONCLUSION

Only 17 (4.2%) respondents had performed a metabolic and bariatric surgery in the past year, and few of those had additional training in MBS. Future work is necessary to better understand optimal practice patterns for adolescent metabolic and bariatric surgery.

Surgeon perceptions of volume threshold and essential practices for pediatric thyroidectomy✰

INTRODUCTION

The topics of sub-specialization and regionalization of care have garnered increased attention among pediatric surgeons. Thyroid surgeries are one such sub-specialty and are commonly concentrated within practices. A national survey was conducted examining current surgeon practices and beliefs surrounding pediatric thyroid surgery.

METHODS

Non-resident members of the American Pediatric Surgical Association (APSA) were surveyed in October 2020. Respondents were stratified based on self-reported thyroid surgical experience. Those who performed thyroid surgery were asked about surgical technique and operative practices; those who did not were asked about referral patterns. All respondents were asked about perceptions surrounding the volume-outcome relationship for pediatric thyroid surgery.

RESULTS

Among 1015 APSA members, 405 (40%) responded, with 79% (317/400) practicing at academic hospitals, 58% (232/401) practicing in major metropolitan area, and 41% (161/392) with over 10 years of attending pediatric surgery experience. Most respondents (88%, n = 356) agreed that thyroid surgery volume affects outcome, though wide variation was reported in the annual case threshold for "high volume" surgery. Eighty-four respondents (21%) reported performing ≥ 1 pediatric thyroid surgery in the past year. Of these, 82% routinely use recurrent laryngeal nerve monitoring, 32% routinely send hemithyroidectomy patients home the same day, and there was little consensus surrounding postoperative hypocalcemia management. The majority of respondents endorse performing thyroid procedures with a colleague.

CONCLUSIONS

Pediatric thyroid surgery appears to be performed by a subset of active pediatric surgeons, most of whom endorse the use of a dual operating team. More evidence is needed to build consensus around additional perioperative practices.

Current status of subspecialization in pediatric surgery: A focus on fetal surgery

BACKGROUND/PURPOSE

Fetal surgery is a growing field within pediatric surgery. We sought to understand practice patterns of pediatric surgeons who subspecialize in fetal surgery.

METHODS

A survey was sent to all active non-trainee surgeons within the American Pediatric Surgical Association. Respondents were stratified based on self-reported fetal affiliations.

RESULTS

Of 1015 surveys, we received 405 responses (40%). Fetal surgery practices were described by 77 self-designated fetal center members. Centers provide prenatal consultation (99%), diagnostic imaging (84%), care/delivery coordination (83%), and/or fetal surgery/procedures (52%). The majority (56%) of fetal programs are directed by surgery and maternal fetal medicine. Pediatric surgeons are represented on the fetal team in 96% of centers. Prenatal consultations are primarily seen by any pediatric surgeon in the group (53%), with the pediatric surgeon on call operating on/caring for the baby postnatally in the majority (64%), regardless of who performed the prenatal consultation. Only 29% of fetal center members performed a fetal operation in the last year. Yearly fetal case numbers vary widely per procedure, with the most common being complex twin procedures and needle-based sclerotherapy.

CONCLUSIONS

Fetal centers vary by services offered, team composition, and interventions performed, with few surgeons performing a wide range of fetal surgery.

Employment search, initial employment experience, and career preferences of recent pediatric surgical fellowship graduates: An APSA survey, part of the right child/right surgeon initiative

BACKGROUND

APSA's Right Child/Right Surgeon Initiative addresses issues concerning patient access to appropriate pediatric surgical care and workforce distribution. The APSA Workforce Committee sought to understand the experiences and motivations of recent graduates of Pediatric Surgery Training Programs entering the workforce.

METHODS

Using APSA membership databases, we identified members who completed fellowship training from 2010 to 2019. An online survey was created using Survey Monkey, and invitations to participate were sent via email.

RESULTS

144 of 447 invited participants responded (32% response rate). 91% of respondents participated in dedicated research prior to fellowship, but only 64% perform research during their employment. 23% completed an additional clinical fellowship, but only 54% currently practice within the second field. When asked to identify the top three factors used to choose a position, the most common responses were "location or geography" (71%), "available mentorship" (53%), and "compensation and benefits" (37%). Describing their first position, 77% reported working in an academic institution, 78% reported working in a metropolitan/urban area, and 55% reported working in a free-standing children's hospital. 94% participate in General Surgery resident education, and 49% are faculty within a Pediatric Surgery fellowship. Overall, 92% of respondents were able to find the type of employment position that they had wanted.

CONCLUSION

In our survey the overwhelming majority of young pediatric surgeons found the type of job they desired. Most report beginning their practice in more populated, urban areas within academic institutions. Geographic location and work environment played heavily into their employment decisions. These preferences could contribute to continued disparity in access to pediatric surgeons between urban and rural America and to dilution of experience for urban surgeons. Possible solutions include alternative incentive programs for employment in less populated areas or new training models for general surgeons in rural areas to train in fundamentals of Pediatric Surgery.
