RESUMO

OBJECTIVE: To determine the representation of Black/AA women surgeons in academic medicine among U.S. medical school faculty and to assess the number of NIH grants awarded to Black/AA women surgeon-scientists over the past 2 decades. SUMMARY OF BACKGROUND DATA: Despite increasing ethnic/racial and sex diversity in U.S. medical schools and residencies, Black/AA women have historically been underrepresented in academic surgery. METHODS: A retrospective review of the Association of American Medical Colleges 2017 Faculty Roster was performed and the number of grants awarded to surgeons from the NIH (1998-2017) was obtained. Data from the Association of American Medical Colleges included the total number of medical school surgery faculty, academic rank, tenure status, and department Chair roles. Descriptive statistics were performed. RESULTS: Of the 15,671 U.S. medical school surgical faculty, 123 (0.79%) were Black/AA women surgeons with only 11 (0.54%) being tenured faculty. When stratified by academic rank, 15 (12%) Black/AA women surgeons were instructors, 73 (59%) were assistant professors, 19 (15%) were associate professors, and 10 (8%) were full professors of surgery. Of the 372 U.S. department Chairs of surgery, none were Black/AA women. Of the 9139 NIH grants awarded to academic surgeons from 1998 and 2017, 31 (0.34%) grants were awarded to fewer than 12 Black/AA women surgeons. CONCLUSION: A significant disparity in the number of Black/AA women in academic surgery exists with few attaining promotion to the rank of professor with tenure and none ascending to the role of department Chair of surgery. Identifying and removing structural barriers to promotion, NIH grant funding, and academic advancement of Black/AA women as leaders and surgeon-scientists is needed.

RESUMO

BACKGROUND: Peripancreatic fluid collection and pseudocyst development is a common sequela following non-operative management (NOM) of pancreatic injuries in children. Our purpose was to review management strategies and assess outcomes. METHODS: A multicenter, retrospective review was conducted of children treated with NOM following blunt pancreatic injury at 22 pediatric trauma centers between the years 2010 and 2015. Organized fluid collections were called "acute peripancreatic fluid collection" (APFC) if identified < 4 weeks and "pseudocyst" if > 4 weeks following injury. Data analysis included descriptive statistics Wilcoxon rank-sum, Kruskal-Wallis and t tests. RESULTS: One hundred patients with blunt pancreatic injury were identified. Median age was 8.5 years (range 1-16). Forty-two percent of patients (42/100) developed organized fluid collections: APFC 64% (27/42) and pseudocysts 36% (15/42). Median time to identification was 12 days (range 7-42). Most collections (64%, 27/42) were observed and 36% (15/42) underwent drainage: 67% (10/15) percutaneous drain, 7% (1/15) needle aspiration, and 27% (4/15) endoscopic transpapillary stent. A definitive procedure (cystogastrostomy/pancreatectomy) was required in 26% (11/42). Patients with larger collections (≥ 7.1 cm) had longer time to resolution. Comparison of outcomes in patients with observation vs drainage revealed no significant differences in TPN use (79% vs 75%, p = 1.00), hospital length of stay (15 vs 25 median days, p = 0.11), time to tolerate regular diet (12 vs 11 median days, p = 0.47), or need for definitive procedure (failure rate 30% vs 20%, p = 0.75). CONCLUSIONS: Following NOM of blunt pancreatic injuries in children, organized fluid collections commonly develop. If discovered early, most can be observed successfully, and drainage does not appear to improve clinical outcomes. Larger size predicts prolonged recovery. LEVEL OF EVIDENCE: III STUDY TYPE: Case series.

RESUMO

Purpose is to evaluate the durability of two commonly used gastrostomy devices. The performance of balloon-type gastrostomy devices was evaluated in an accelerated aging failure mode as well as a feeding tube interlock pullout failure mode. Two commonly used devices were tested: MINI (Applied Medical Technology Inc.) and MIC-Key (Kimberly Clark/Ballard Medical). In the aging test, devices (n = 20) from each manufacturer were pressurized and subjected to controlled pH and temperature conditions to evaluate the product life. In the pullout failure test, devices were subjected to controlled mechanical loading to evaluate the force at which each plastic interlock pulls out of the rubber that encapsulates it. In the aging testing, the MIC-Key devices had a lifespan of 98 ± 34 h and the MINI survived for 1187 ± 422 h. The difference was statistically significant (p < 1 × 10-9). In the pullout testing, the MIC-Key failed at 183 ± 24 N whereas the MINI failed at 202 ± 26 N (p < 0.04). Pullout strength for both devices appears adequate in view of estimated in vivo loads during normal use of the device with the MINI requiring a statistically significantly greater pullout strength. Although the aging tests were performed using an accelerated protocol, the aging tests suggest that the in vivo lifespan and failure mode of the MINI may be superior to the MIC-Key.

RESUMO

BACKGROUND: Pediatric ulcerative colitis (UC) treatment has changed dramatically with the introduction of multiple biologics. The goal of this study was to determine the effectiveness of these new biologics on achieving remission, nutritional impact, and eventual need for surgery in children. METHODS: We retrospectively analyzed hospital records of UC patients (ages 1-19) seen at a pediatric gastroenterology clinic between January 2012 andAugust 2020. Patients were divided into groups: 1) medically without biologics or surgery; 2) patients treated with one biologic; and 3) patients treated with multiple biologics 4)patients that underwent colectomy. RESULTS: There were 115 UC patients with a mean follow-up of 5.9 ± 3.7 years (1 month-15.3 years). PUCAI score at diagnosis was mild in 52 patients (45%), moderate in 25 (21%), and severe in 5 (4.3%). PUCAI score for 33 patients (29%) could not be calculated. There were 48 (41.3%) in group 1 with 58% remission, 34 (29.6%) in group 2 with 71% remission, 24 (20.8%) in group 3 with 29% remission, and only 9 (7.8%) in group 4 with 100% remission. The majority (55%) of surgical patients had colectomy within the first year of diagnosis. BMI improved after surgery (P = 0.001). The change from one biologic to others did not improve nutrition over time. DISCUSSION: New biologics are changing the landscape in maintaining remission from UC. The current need for surgery is much lower than previously published studies. In medically refractive UC, nutritional status only improved after surgery. Addition of another biologic for medically refractory ulcerative colitis in order to avoid surgery must take into account the positive impact surgery has on nutrition and disease remission.

RESUMO

INTRODUCTION: Bias and discrimination remain pervasive in the medical field and increase the risk of burnout, mental health disorders, and medical errors. The experiences of APSA members with bias and discrimination are unknown, therefore the APSA committee on Diversity, Equity and Inclusion conducted a survey to characterize the prevalence of bias and discrimination. METHODS: 1558 APSA members were sent an anonymous survey, of which 423 (27%) responded. Respondents were asked about their demographics, knowledge of implicit bias, and experience of bias and discrimination within their primary workplace, APSA, and APSA committees. Data were analyzed using Fisher's Exact test, Kruskal-Wallis test, and multivariable logistic regression as appropriate with significance defined as p<0.05. RESULTS: Discrimination was reported across all levels of practice, academic appointments, race, ethnicity, and gender identities. On multivariable analysis, surgical trainees (OR 3.6) as well as Asian American and Pacific Islander (OR 4.8), Black (OR 5.2), Hispanic (OR 8.2) and women (OR 8.7) surgeons were more likely to experience bias and discrimination in the workplace. Community practice surgeons were more likely to experience discrimination within APSA committees (OR 3.6). Members identifying as Asian (OR 0.4), or women (OR 0.6) were less likely to express comfort reporting instances of bias and discrimination. CONCLUSION: Workplace discrimination exists across all training levels, academic appointments, and racial and gender identities. Trainees and racial- and gender-minority surgeons report disproportionately high prevalence of bias and discrimination. Improving reporting mechanisms and implicit bias training are possible initiatives in addressing these findings.

RESUMO

INTRODUCTION: There are existing healthcare disparities in pediatric surgery today. Identity and racial incongruity between patients and providers contribute to systemic healthcare inequities and negatively impacts health outcomes of minoritized populations. Understanding the current demographics of the American Pediatric Surgical Association and therefore the cognitive diversity represented will help inform how best to strategically build the organization to optimize disparity solutions and improve patient care. METHODS: 1558 APSA members were sent an anonymous electronic survey. Comparative data was collected from the US Census Bureau and the Association of American Medical Colleges. Results were analyzed using standard statistical tests. RESULTS: Of 423 respondents (response rate 27%), the race and ethnicity composition were 68% non Hispanic White, 12% Asian American and Pacific Islander, 6% Hispanic, 5% multiracial, and 4% Black/African American. Respondents were 35% women, 63% men, and 1% transgender, androgyne, or uncertain. Distribution of sexual identity was 97% heterosexual and 3% LGBTQIA. Religious identity was 50% Christian, 22% Agnostic/Atheist, 11% Jewish, 3% Hindu, and 2% Muslim. 32% of respondents were first-generation Americans. Twenty-four different primary languages were spoken, and 46% of respondents were conversational in a second language. These findings differ in meaningful ways from the overall American population and from the population of matriculants in American medical schools. CONCLUSION: There are substantial differences in the racial, gender, and sexual identity composition of APSA members compared with the overall population in the United States. To achieve excellence in patient care and innovate solutions to existing disparities, representation, particularly in leadership is essential. TYPE OF STUDY: Survey; original research. LEVEL OF EVIDENCE: Level IV.

RESUMO

Despite progress, diversity and minority representation within the pediatric surgery workforce still does not match the expansive backgrounds of the patients we treat. The problem stems from underrepresentation of minority populations at every step along the pediatric surgery training pathway. Strategies aimed at improving diversity and representation in medical school, general surgery residencies, and ultimately pediatric surgery fellowship are necessary to assemble a more diverse pool of pediatric surgeons. The aim of this paper is to review the current demographic make-up of medical and surgical specialties, highlight the value of diversity, and provide evidence-based strategies for increasing minority representation throughout the pediatric surgery pathway. Future patients will be better served with a more representative pediatric surgery workforce.

RESUMO

Introduction: Massive splenomegaly in children can complicate minimally invasive splenectomy. Splenic artery embolization (SAE) before splenectomy has been shown to decrease splenic volume, reduce intraoperative blood loss, and decrease conversion rates in laparoscopic surgery. Our objective was to review our recent experience with immediate preoperative SAE in massive splenomegaly for pediatric patients using both laparoscopic and robotic techniques. Materials and Methods: We retrospectively reviewed preoperative SAE outcomes in pediatric patients with massive splenomegaly undergoing minimally invasive splenectomy between January 2018 and July 2021. Results: Four patients, 3 female, ages 5-18 years, had SAE immediately before minimally invasive splenectomy. Two cases were completed robotically, one laparoscopically, and one laparoscopic case required conversion to open. SAE time ranged from 69 to 92 minutes. Time between embolization and surgical start ranged from 26 to 56 minutes, with operative times from 153 to 317 minutes. Estimated blood loss ranged from <10 to 150 mL. Mean length of stay was 3.5 days (range 2-6). Postoperative complications included one patient with ileus and another with concurrent gastritis and urinary tract infection. Splenic size comparisons were difficult to perform due to morselization of the spleen; however, excised spleen weights, measurements, and surgeon's impression suggested decreased size of the spleen after SAE. There were no transfusions, postembolization complications, or deaths. Conclusion: SAE subjectively appears to decrease splenic distension, which should allow for easier manipulation and possibly better visualization of splenic hilar vessels during minimally invasive surgery. Immediate preoperative SAE is safe and feasible and should be considered in pediatric patients with massive splenomegaly.

RESUMO

IMPORTANCE: The lack of underrepresented in medicine physicians within US academic surgery continues, with Black surgeons representing a disproportionately low number. OBJECTIVE: To evaluate the trend of general surgery residency application, matriculation, and graduation rates for Black trainees compared with their racial and ethnic counterparts over time. DESIGN, SETTING, AND PARTICIPANTS: In this nationwide multicenter study, data from the Electronic Residency Application Service (ERAS) for the general surgery residency match and Graduate Medical Education (GME) surveys of graduating general surgery residents were retrospectively reviewed and stratified by race, ethnicity, and sex. Analyses consisted of descriptive statistics, time series plots, and simple linear regression for the rate of change over time. Medical students and general surgery residency trainees of Asian, Black, Hispanic or Latino of Spanish origin, White, and other races were included. Data for non-US citizens or nonpermanent residents were excluded. Data were collected from 2005 to 2018, and data were analyzed in March 2021. MAIN OUTCOMES AND MEASURES: Primary outcomes included the rates of application, matriculation, and graduation from general surgery residency programs. RESULTS: Over the study period, there were 71 687 applicants, 26 237 first-year matriculants, and 24 893 graduates. Of 71 687 applicants, 24 618 (34.3%) were women, 16 602 (23.2%) were Asian, 5968 (8.3%) were Black, 2455 (3.4%) were Latino, and 31 197 (43.5%) were White. Women applicants and graduates increased from 29.4% (1178 of 4003) to 37.1% (2293 of 6181) and 23.5% (463 of 1967) to 33.5% (719 of 2147), respectively. When stratified by race and ethnicity, applications from Black women increased from 2.2% (87 of 4003) to 3.5% (215 of 6181) (P < .001) while applications from Black men remained unchanged (3.7% [150 of 4003] to 4.6% [284 of 6181]). While the matriculation rate for Black women remained unchanged (2.4% [46 of 1919] to 2.3% [52 of 2264]), the matriculation rate for Black men significantly decreased (3.0% [57 of 1919] to 2.4% [54 of 2264]; P = .04). Among Black graduates, there was a significant decline in graduation for men (4.3% [85 of 1967] to 2.7% [57 of 2147]; P = .03) with the rate among women remaining unchanged (1.7% [33 of 1967] to 2.2% [47 of 2147]). CONCLUSIONS AND RELEVANCE: Findings of this study show that the underrepresentation of Black physicians at every stage in surgical training pipeline persists. Black men are especially affected. Identifying factors that address intersectionality and contribute to the successful recruitment and retention of Black trainees in general surgery residency is critical for achieving racial and ethnic as well as gender equity.

RESUMO

BACKGROUND: Diagnosing NAT (non-accidental trauma) includes a skeletal survey to identify injuries. A follow-up survey is performed for missed injuries. This study examines the necessity of follow-up surveys. METHODS: The trauma database identified cases of suspected NAT in <4 years olds (2013-2014). Data were stratified by survey, age, injury, then analyzed for the prevalence of findings. All analyses (relative risk, prevalence and odds ratios) utilized RealStats Resource Pack (Trento, Italy). RESULTS: 79% positive initial findings and no new follow up findings. Those with negative initial imaging, had no missed injuries. Initial scans were 27.6X more likely to be positive. Fractured skull (31.3), femur (17.2) and ribs (15.7) were the most prevalent. No pelvic fractures and <1% spinal injuries despite both having the greatest radiation exposure. Repeat scans rarely identify findings for age >12 months. CONCLUSIONS: Follow-up skeletal surveys maybe unnecessary without clinical evidence. Uncommon pelvic and spinal fractures may warrant exclusion from surveys unless clinically indicated.

RESUMO

BACKGROUND/PURPOSE: Endoscopic retrograde cholangiopancreatography (ERCP) is an adjunct for pediatric pancreatic injury management, but its use and utility in pediatric patients are unclear. We set out to evaluate the use of ERCP and its effects on outcomes. METHODS: A retrospective review was performed for children who had pancreatic injuries at 22 pediatric trauma centers between 2010 and 2015. ERCP details and outcomes were collected. Analysis was performed using descriptive statistics and Wilcoxon rank-sum tests. RESULTS: ERCP was used at 14/22 centers for 26 patients. Indications were duct evaluation, duct leak control, pseudocyst, fistula, and stricture. ERCP altered management or improved outcomes in 13/26 (50%), most commonly in patients with ERCP for duct evaluation, stricture, and fistula. In patients managed nonoperatively, those with early endoscopic intervention (within one week of injury) with stent or sphincterotomy (n=9) had similar time to regular diet [median (IQR)]: [10 (7-211) vs 7 (4-12) days; p=0.55], similar hospital days: [12 (8-20) vs 11 (6-19) days, p=0.63], and similar time on parenteral nutrition: [17 (10-40) vs 10 (6-18) days; p=0.19] compared to patients who were only observed. CONCLUSIONS: In children with blunt pancreatic injury, ERCP can be useful to diagnose duct injury and for management of late complications such as stricture and fistula. However, early endoscopic intervention for pancreatic duct disruption may not improve outcome or expedite recovery. Further study is needed. STUDY TYPE: Retrospective Study; Treatment Study. LEVEL OF EVIDENCE: III.

RESUMO

BACKGROUND: Guidelines for nonoperative management (NOM) of high-grade pancreatic injuries in children have not been established, and wide practice variability exists. The purpose of this study was to evaluate common clinical strategies across multiple pediatric trauma centers to develop a consensus-based standard clinical pathway. METHODS: A multicenter, retrospective review was conducted of children with high-grade (American Association of Surgeons for Trauma grade III-V) pancreatic injuries treated with NOM between 2010 and 2015. Data were collected on demographics, clinical management, and outcomes. RESULTS: Eighty-six patients were treated at 20 pediatric trauma centers. Median age was 9 years (range, 1-18 years). The majority (73%) of injuries were American Association of Surgeons for Trauma grade III, 24% were grade IV, and 3% were grade V. Median time from injury to presentation was 12 hours and median ISS was 16 (range, 4-66). All patients had computed tomography scan and serum pancreatic enzyme levels at presentation, but serial enzyme level monitoring was variable. Pancreatic enzyme levels did not correlate with injury grade or pseudocyst development. Parenteral nutrition was used in 68% and jejunal feeds in 31%. 3Endoscopic retrograde cholangiopancreatogram was obtained in 25%. An organized peripancreatic fluid collection present for at least 7 days after injury was identified in 59% (42 of 71). Initial management of these included: observation 64%, percutaneous drain 24%, and endoscopic drainage 10% and needle aspiration 2%. Clear liquids were started at a median of 6 days (IQR, 3-13 days) and regular diet at a median of 8 days (IQR 4-20 days). Median hospitalization length was 13 days (IQR, 7-24 days). Injury grade did not account for prolonged time to initiating oral diet or hospital length; indicating that the variability in these outcomes was largely due to different surgeon preferences. CONCLUSION: High-grade pancreatic injuries in children are rare and significant variability exists in NOM strategies, which may affect outcomes and effective resource utilization. A standard clinical pathway is proposed. LEVEL OF EVIDENCE: Therapeutic/care management, level V (case series).

RESUMO

Jejunal diverticulosis is a rare, acquired pathology of the small bowel. While most patients are asymptomatic, the condition is difficult to diagnose. It may present with chronic abdominal pain, diarrhoea, bloating and complications including malabsorption, diverticulitis, bleeding, intestinal obstruction or perforation. This is a case presentation of a 27-year-old woman with a history of necrotising enterocolitis (NEC) requiring surgical resection as a premature newborn who presented with recurrent abdominal pain and was found to have several small bowel diverticula intraoperatively. She underwent resection with complete resolution of symptoms over a 2-year follow-up. This is the first case report to suggest that small bowel diverticular disease as a long-term complication of NEC may result in chronic morbidity in long-term survivors.

RESUMO

Gastrointestinal stromal tumor (GIST) is a mesenchymal tumor that is rare in children. We report a case of GIST in a pediatric patient. A 16-year-old adolescent girl presented after an episode of syncope preceded by one episode of melena. Physical examination results were normal except for Hemoccult-positive stool. Laboratory studies included a hemoglobin level of 6.1 g/dL; complete metabolism profile and coagulation studies revealed normal results. She was transfused with 2 units of packed red blood cells, and an urgent esophagogastroduodenoscopy was performed. Esophagogastroduodenoscopy demonstrated 3 submucosal sessile masses in the gastric antrum ranging from 1 to 3 cm with normal overlying mucosa except for one of the lesions, which was ulcerated. Endoscopic biopsies stained positive for CD117 and were consistent with GIST. Radiologic imaging demonstrated the endoscopically visualized masses and also showed a solitary 1-cm lesion within the liver. She underwent partial gastrectomy and open biopsy of the hepatic lesion. Histologic examination confirmed GIST with hepatic metastasis. Typically with GIST, esophagogastroduodenoscopy will demonstrate a normal surface mucosa and a firm, smooth yellowish submucosal mass, which can be ulcerated. In some cases these tumors can be missed because of their frequent submucosal and extraluminal growth. This case, to our knowledge, is one of the first reports of the endoscopic appearance of GIST in a pediatric patient. Although a rare entity in children, GIST should be considered in pediatric patients with endoscopically visualized submucosal gastric masses.

RESUMO

BACKGROUND/PURPOSE: Multisystem organ failure (MSOF) is a major cause of morbidity and mortality in the critically ill patient. Animal models of endotoxin-induced sepsis were used to develop therapeutic regimens, which thus far have failed in clinical trials. Because multiple etiologies of MSOF affect the intestine, the authors hypothesized that during sepsis the gut may act as a possible trigger of the inflammatory cascade. As ischemia and reperfusion of the small intestine disrupts gut barrier function, thereby activating systemic inflammatory responses, the authors evaluated a murine model of ischemia/reperfusion to investigate these systemic responses to local mucosal and epithelial injury. METHODS: C57BL/10 and Balb/c mice underwent variable amounts of gut ischemia by superior mesenteric artery occlusion. Animals were evaluated for survival as well as gross and microscopic intestinal damage. RESULTS: Maximal ischemic damage occurred in the distal jejunum and proximal ileum. More severe epithelial damage and transmural inflammation were observed in C57BL/10 mice, which correlated with a higher mortality. CONCLUSIONS: This model mimics what is observed clinically with intestinal injury resulting from a progressive ischemic insult with eventual systemic manifestations. This reproducible model of systemic inflammation elicits variable responses from genetically different animals, the results of which may lead to a better understanding of MSOF.
