Evaluating Outcomes of Nonaccidental Trauma in Military Children

BACKGROUND

Nonaccidental trauma (NAT), or child abuse, is a leading cause of childhood injury and death in the US. Studies demonstrate that military-affiliated individuals are at greater risk of mental health complication and family violence, including child maltreatment. There is limited information about the outcomes of military children who experience NAT. This study compares the outcomes between military-dependent and civilian children diagnosed with NAT.

STUDY DESIGN

A single-institution, retrospective review of children admitted with confirmed NAT at a Level I trauma center was performed. Data were collected from the institutional trauma registry and the Child Abuse Team's database. Military affiliation was identified using insurance status and parental or caregiver self-reported active-duty status. Demographic and clinical data including hospital length of stay (LOS), morbidity, specialty consult, and mortality were compared.

RESULTS

Among 535 patients, 11.8% (n = 63) were military-affiliated. The median age of military-associated patients, 3 months (interquartile range [IQR] 1 to 7), was significantly younger than civilian patients, 7 months (IQR 3 to 18, p < 0.001). Military-affilif:ated patients had a longer LOS of 4 days (IQR 2 to 11) vs 2 days (IQR 1 to 7, p = 0.041), increased morbidity or complication (3 vs 2 counts, p = 0.002), and a higher mortality rate (10% vs 4%, p = 0.048). No significant difference was observed in the number of consults or injuries, trauma activation, or need for surgery.

CONCLUSIONS

Military-affiliated children diagnosed with NAT experience more adverse outcomes than civilian patients. Increased LOS, morbidity or complication, and mortality suggest military-affiliated patients experience more life-threatening NAT at a younger age. Larger studies are required to further examine this population and better support at-risk families.

Factors Associated with Postoperative Opioid Use in Adolescents

BACKGROUND

We aimed to identify factors associated with postoperative prescription opioid use in adolescents.

METHODS

Adolescents aged 13-20 years undergoing surgery were prospectively recruited from a children's hospital. Adolescent-parent dyads completed a preoperative survey, measuring clinical and sociodemographic factors, and two postoperative surveys evaluating self-reported opioid use at 30- and 90-days. Poisson regression analysis identified factors associated with the number of pills used within 90-days, adjusting for age, gender, race/ethnicity, surgery type, and pain at discharge.

RESULTS

We enrolled 119 adolescents who reported postoperative opioid use following posterior spinal fusion (PSF) (50 %), arthroscopy (23 %), pectus excavatum repair (11 %), tonsillectomy (8 %), and hip reconstruction (7 %). Overall, 81 % of adolescents reported unused opioids. The median pain score at discharge was 7 (IQR:5-8). Adolescents reported using a median of 7 (IQR:2-15) opioid pills, with 20 (IQR:7-30) pills left unused. Compared to all other surgeries, adolescents undergoing PSF reported the highest median pill use (10, IQR:5-29; p = 0.004). Adolescents undergoing tonsillectomy reported the lowest median pill use (1, IQR:0-7; p = 0.03). On regression analysis, older patient age was associated with a 12 % increase in pill use (95 % CI:3%-23 %). Undergoing PSF was associated with a 63 % increase in pill use (95 % CI:15%-31 %). Each additional pain scale point reported at discharge was associated with a 13 % increase in pill use (95 % CI:5%-22 %).

CONCLUSIONS

Older age, surgery type, and patient-reported pain at discharge are associated with postoperative prescription opioid use in adolescents. Understanding patient and surgery-specific factors associated with opioid use may guide surgeons to minimize excess opioid prescribing.

Identification and Evaluation of Non-Accidental Trauma in the Pediatric Population: A Clinical Review

Non-accidental trauma (NAT) is a major cause of morbidity and mortality for children around the world and most significantly impacts children under one year of age. Prompt and comprehensive treatment of these children relies on a high index of suspicion from any medical provider that treats pediatric patients. This review discusses those most at risk for experiencing NAT, and common initial presentations, to assist providers in the identification of potential victims. In addition, this review provides guidance on the recommended workup for these patients so that the full extent of associated injuries may be identified and the appropriate healthcare team may be assembled.

A Comparative Study of Laparoscopic versus Open Management of Index Small Bowel Obstruction in Children

INTRODUCTION

There is limited literature on the optimal approach to treat adhesive small bowel obstruction (ASBO) in children. We sought to compare rates and outcomes of laparoscopic (LAP) and open (OPEN) surgery for pediatric ASBO.

METHODS

A California statewide database was used to identify children (<18 years old) with an index ASBO from 2007 to 2020. The primary outcome was the type of operative management: LAP or OPEN. Secondary outcomes were hospital characteristics, patient demographics, and postoperative complications. We excluded patients treated non-operatively.

RESULTS

Our study group had 545 patients. 381 (70%) underwent OPEN and 164 (30%) LAP during the index admission. Over the study period, there was increasing use of laparoscopic surgery, with higher use in older children (p < 0.001). LAP was associated with fewer overall complications (65.2% vs. 81.6%, p < 0.001), with a decreasing trend in complications over time (p < 0.001). The LAP group had significantly lower rates of bowel resection (4.9% vs. 17.1%, p < 0.001), length of stay (LOS) (17 vs. 23 days, p < 0.001), and TPN use (12.2% vs. 29.1%, p < 0.001). Mortality rates were equivalent. Although the LAP group had lower readmission rates (22.6% vs. 37.3%, p < 0.001), the length of time between discharge and readmission was similar (171 vs. 165 days, p = 0.190).

DISCUSSION

The use of laparoscopic surgery for index ASBO increased over the study period. However, it was less commonly utilized in younger children. LAP had fewer overall complications as well as shorter LOS, decreased TPN use, and fewer readmissions. The benefits and risks of each approach must be weighed.

Outcomes of Extracorporeal Life Support Utilization for Pediatric Patients With COVID-19 Infections

Outcomes of pediatric patients who received extracorporeal life support (ECLS) for COVID-19 remain poorly described. The aim of this multi-institutional retrospective observational study was to evaluate these outcomes and assess for prognostic factors associated with in-hospital mortality. Seventy-nine patients at 14 pediatric centers across the United States who received ECLS support for COVID-19 infections between January 2020 and July 2022 were included for analysis. Data were extracted from the electronic medical record. The median age was 14.5 years (interquartile range [IQR]: 2-17 years). Most patients were female (54.4%) and had at least one pre-existing comorbidity (84.8%), such as obesity (44.3%, median body mass index percentile: 97% [IQR: 67.5-99.0%]). Venovenous (VV) ECLS was initiated in 50.6% of patients. Median duration of ECLS was 12 days (IQR: 6.0-22.5 days) with a mean duration from admission to ECLS initiation of 5.2 ± 6.3 days. Survival to hospital discharge was 54.4%. Neurological deficits were reported in 16.3% of survivors. Nonsurvivors were of older age (13.3 ± 6.2 years vs. 9.3 ± 7.7 years, p  = 0.012), more likely to receive renal replacement therapy (63.9% vs. 30.2%, p  = 0.003), demonstrated longer durations from admission to ECLS initiation (7.0 ± 8.1 days vs. 3.7 ± 3.8 days, p  = 0.030), and had higher rates of ECLS-related complications (91.7% vs. 69.8%, p  = 0.016) than survivors. Pediatric patients with COVID-19 who received ECLS demonstrated substantial morbidity and further investigation is warranted to optimize management strategies.

Cervical Collar-Associated Pressure Injury in Pediatric Trauma Patients: A Western Pediatric Surgery Research Consortium Study

BACKGROUND

Healthcare-associated pressure injuries (HAPI) are known to be associated with medical devices and are preventable. Cervical spine immobilization is commonly utilized in injured children prior to clinical clearance or for treatment of an unstable cervical spinal injury. The frequency of HAPI has been quantified in adults with cervical spine immobilization but has not been well-described in children. The aim of this study was to describe characteristics of children who developed HAPI associated with cervical immobilization.

METHODS

We analyzed a retrospective cohort of children (0-18 years) who developed a stage two or greater cervical HAPI. This cohort was drawn from an overall sample of 49,218 registry patients treated over a five-year period (2017-2021) at ten pediatric trauma centers. Patient demographics, injury characteristics, and cervical immobilization were tabulated to describe the population.

RESULTS

The cohort included 32 children with stage two or greater cervical HAPI. The median age was 5 years (IQR 2-13) and 78% (n = 25) were admitted to the intensive care unit. The median (IQR) time to diagnosis of HAPI was 11 (7-21) days post-injury. The majority of cervical HAPI (78%, 25/32) occurred in children requiring immobilization for cervical injuries, with only four children developing HAPI after wearing a prophylactic cervical collar in the absence of a cervical spine injury.

CONCLUSION

Advanced-stage HAPI associated with cervical collar use in pediatric trauma patients is rare and usually occurs in patients with cervical spine injuries requiring immobilization for treatment. More expedient cervical spine clearance with MRI is unlikely to substantially reduce cervical HAPI in injured children.

A Window of Opportunity: Understanding Pediatric Falls Using Area Deprivation Index

INTRODUCTION

The purpose of our study is to assess neighborhood socioeconomic disadvantage (NSD) as a risk factor for window falls (WF) in children.

METHODS

A single institution retrospective review was performed of patients ≤18 years old with fall injuries treated at a Level I trauma center between 2018 and 2021. Demographic, injury, and NSD characteristics which were collected from a trauma registry were analyzed and compared between WF versus non-window falls. Area Deprivation Index (ADI) was used to measure NSD levels based on patients' home address 9-digit zip code, with greater NSD being defined as ADI quintiles 4 and 5. Property type was used to compare falls that took place at single-family homes versus apartment buildings.

RESULTS

Among 1545 pediatric fall injuries, 194 were WF, of which 60 % were male and 46 % were Hispanic. WF patients were younger than NWF patients (median age WF 3.2 vs. age 4.3, p<0.047). WF patients were more likely to have a depressed Glasgow Coma Scale (GCS score ≤12, WF 9 % vs. 3 %) and sustain greater head/neck injuries (median AIS 3vs. AIS 2, p<0.001) when compared to NWF. WF patients had longer hospital and ICU lengths of stay than NWF patients (p<0.001 and p<0.001, respectively). WF patients were more likely to live in areas of greater NSD than NWF patients (53 % vs. 35 %, p<0.001), and 73 % of all WF patients lived in apartments or condominiums.

CONCLUSIONS

Window fall injuries were associated with lower GCS, greater severity of head/neck injuries, and longer hospital and ICU length of stay than non-window falls. ADI research can provide meaningful data for targeted injury prevention programs in areas where children are at higher risk of window falls.

Decision-Making in Pleural Drainage Following Lung Resection in Children: A Western Pediatric Surgery Research Consortium Survey

INTRODUCTION

Studies of adults undergoing lung resection indicated that selective omission of pleural drains is safe and advantageous. Significant practice variation exists for pleural drainage practices for children undergoing lung resection. We surveyed pediatric surgeons in a 10-hospital research consortium to understand decision-making for placement of pleural drains following lung resection in children.

METHODS

Faculty surgeons at the 10 member institutions of the Western Pediatric Surgery Research Consortium completed questionnaires using a REDCap survey platform. Descriptive statistics and bivariate analyses were used to characterize responses regarding indications and management of pleural drains following lung resection in pediatric patients.

RESULTS

We received 96 responses from 109 surgeons (88 %). Most surgeons agreed that use of a pleural drain after lung resection contributes to post-operative pain, increases narcotic use, and prolongs hospitalization. Opinions varied around the immediate use of suction compared to water seal, and half routinely completed a water seal trial prior to drain removal. Surgeons who completed fellowship within the past 10 years left a pleural drain after wedge resection in 45 % of cases versus 78 % in those who completed fellowship more than 10 years ago (p = 0.001). The mean acceptable rate of unplanned post-operative pleural drain placement when pleural drainage was omitted at index operation was 6.3 % (±4.6 %).

CONCLUSIONS

Most pediatric surgeons use pleural drainage following lung resection, with recent fellowship graduates more often omitting it. Future studies of pleural drain omission demonstrating low rates of unplanned postoperative pleural drain placement may motivate practice changes for children undergoing lung resection.

Application of a Machine Learning Algorithm in Prediction of Abusive Head Trauma in Children

PURPOSE

We explored the application of a machine learning algorithm for the timely detection of potential abusive head trauma (AHT) using the first free-text note of an encounter and demographic information.

METHODS

First free-text physician notes and demographic information were collected for children under 5 years of age at a Level 1 Trauma Center. The control group, which included patients with head/neck injury, was compared to those with AHT diagnosed by the Child Protective Team. Differential scores accounted for words overrepresented in AHT patient vs. control notes. Sentiment scores were reflective of note positivity/negativity and subjectivity scores accounted for note subjectivity/objectivity. The composite scores reflected the patient's differential score modified by the subjectivity score. Composite, sentiment, and subjectivity scores combined with demographic information trained a Random Forest (RF) machine learning algorithm to predict AHT.

RESULTS

Final composite scores with demographic information were highly associated with AHT in a test dataset. The control group included 587 patients and the test group included 193 patients. Combining composite scores with demographic information into the RF model improved AHT classification area under the curve (AUC) from 0.68 to 0.78, with an overall accuracy of 84%. Feature importance analysis of our RF model revealed that composite score, sentiment, age, and subjectivity were the most impactful predictors of AHT. The sentiment was not significantly different between control and AHT notes (p = 0.87), while subjectivity trended higher for AHT notes (p = 0.081).

CONCLUSION

We conclude that a machine learning algorithm can recognize patterns within free-text notes and demographic information that aid in AHT detection in children.

Trends in Management of Index Adhesive Small Bowel Obstruction in Children

INTRODUCTION

To examine practice patterns and surgical outcomes of nonoperative versus operative management (OPM) of children presenting with an index adhesive small bowel obstruction (ASBO).

METHODS

A California statewide health discharge database was used to identify children (<18 y old) with an index ASBO from 2007 to 2020. The primary study outcome was evaluating initial management patterns (nonoperative versus OPM and early [≤3 d] versus late surgery [>3 d]) of ASBO. Secondary outcomes were hospital characteristics, patient demographics, and postoperative complications.

RESULTS

Of the 2297 patients identified, 1948 (85%) underwent OPM for ASBO during the index admission. Of these, 14.7% underwent early surgery within 3 d. Teaching hospitals had higher operative intervention than nonteaching centers (87.1% versus 83.7%, P = 0.034). OPM was the highest in 0-5-year-olds compared to other ages (89% versus 82%, P < 0.001). In comparison to early surgery, late surgery was associated with longer length of stay (early 7[interquartile range 5-10], late 9[interquartile range 6-17], P < 0.001), increased infectious complications (16.4% versus 9.8%, P = 0.004), and greater use of total parenteral nutrition (28.0% versus 14.3%, P = 0.001); there was no difference in bowel resection (21% versus 18%, P = 0.102) or mortality (P = 0.423).

CONCLUSIONS

Our pediatric study demonstrated a high rate of OPM for index ASBO, especially in newborns and toddlers. Although operative intervention, especially late surgery, was associated with increased length of stay, increased infectious complications, and increased total parenteral nutrition use, the rates of bowel resection and mortality did not differ by management strategy. These trends need to be further evaluated to optimize outcomes.

Machine learning to predict pediatric choledocholithiasis: A Western Pediatric Surgery Research Consortium retrospective study

BACKGROUND

The purpose of this study was to accurately predict pediatric choledocholithiasis with clinical data using a computational machine learning algorithm.

METHODS

A multicenter retrospective cohort study was performed on children <18 years of age who underwent cholecystectomy between 2016 to 2019 at 10 pediatric institutions. Demographic data, clinical findings, laboratory, and ultrasound results were evaluated by bivariate analyses. An Extra-Trees machine learning algorithm using k-fold cross-validation was used to determine predictive factors for choledocholithiasis. Model performance was assessed using the area under the receiver operating characteristic curve on a validation dataset.

RESULTS

A cohort of 1,597 patients was included, with an average age of 13.9 ± 3.2 years. Choledocholithiasis was confirmed in 301 patients (18.8%). Obesity was the most common comorbidity in all patients. Choledocholithiasis was associated with the finding of a common bile duct stone on ultrasound, increased common bile duct diameter, and higher serum concentrations of aspartate aminotransferase, alanine transaminase, lipase, and direct and peak total bilirubin. Nine features (age, body mass index, common bile duct stone on ultrasound, common bile duct diameter, aspartate aminotransferase, alanine transaminase, lipase, direct bilirubin, and peak total bilirubin) were clinically important and included in the machine learning algorithm. Our 9-feature model deployed on new patients was found to be highly predictive for choledocholithiasis, with an area under the receiver operating characteristic score of 0.935.

CONCLUSION

This multicenter study uses machine learning for pediatric choledocholithiasis. Nine clinical factors were highly predictive of choledocholithiasis, and a machine learning model trained using medical and laboratory data was able to identify children at the highest risk for choledocholithiasis.

Understanding the burden of traumatic injuries at the United States-Mexico border: A scoping review of the literature

ABSTRACT

The US-Mexico border is the busiest land crossing in the world and faces continuously increasing numbers of undocumented border crossers. Significant barriers to crossing are present in many regions of the border, including walls, bridges, rivers, canals, and the desert, each with unique features that can cause traumatic injury. The number of patients injured attempting to cross the border is also increasing, but significant knowledge gaps regarding these injuries and their impacts remain. The purpose of this scoping literature review is to describe the current state of trauma related to the US-Mexico border to draw attention to the problem, identify knowledge gaps in the existing literature, and introduce the creation of a consortium made up of representatives from border trauma centers in the Southwestern United States, the Border Region Doing Research on Trauma Consortium. Consortium members will collaborate to produce multicenter up-to-date data on the medical impact of the US-Mexico border, helping to elucidate the true magnitude of the problem and shed light on the impact cross-border trauma has on migrants, their families, and the US health care system. Only once the problem is fully described can meaningful solutions be provided.

Pediatric DUCT Score: A Highly Specific Predictive Model for Choledocholithiasis in Children

BACKGROUND

Current adult guidelines for the management of choledocholithiasis (CDL) may not be appropriate for children. We hypothesized adult preoperative predictive factors are not reliable for predicting CDL in children.

STUDY DESIGN

A multicenter retrospective cohort study was performed evaluating children (≤18 years of age) who underwent cholecystectomy for gallstone disease at 10 children's hospitals. Univariate and multivariable analyses were used to identify factors independently associated with CDL. Patients were stratified into risk groups demonstrating the presence of predictive factors for CDL. Statistical analyses were performed, and chi-square analyses were used with a significance of p < 0.05.

RESULTS

A total of 979 cholecystectomy patients were analyzed. The diagnosis of CDL was confirmed in 222 patients (22.7%) by magnetic resonance cholangiopancreatography, endoscopic retrograde cholangiopancreatography, or intraoperative cholangiography. Three predictive factors were identified: (1) Dilated common bile duct ≥6 mm; (2) Ultrasound with Choledocholithiasis; and (3) Total bilirubin ≥1.8 mg/dL (pediatric DUCT criteria). Risk groups were based on the number of predictive factors: very high (3), high (2), intermediate (1), and low (0). The pediatric DUCT criteria demonstrated accuracies of >76%, specificity of >78%, and negative predictive values of >79%. Adult factors (elevated aspartate aminotransferase/alanine aminotransferase, pancreatitis, BMI, and age) did not independently predict CDL. Based on risk stratification, the high- and very-high-risk groups demonstrated higher predictive capacity for CDL.

CONCLUSIONS

Our study demonstrated that the pediatric DUCT criteria, incorporating common bile duct dilation, choledocholithiasis seen on ultrasound, and total bilirubin ≥1.8 mg/dL, highly predicts the presence of choledocholithiasis in children. Other adult preoperative factors are not predictive of common bile duct stone in children.

Pediatric penetrating thoracic trauma: Examining the impact of trauma center designation and penetrating trauma volume on outcomes

INTRODUCTION

We analyzed the impact of treating center designation and case volume of penetrating trauma on outcomes after pediatric penetrating thoracic injuries (PTI).

METHODS

PTI patients <18 years were identified from the National Trauma Data Bank (2013-2016). Centers were categorized by type (Pediatric or Adult) and designation status (Level I, Level II, and other). Performance was calculated as the difference between observed and expected mortality and standardized using the total penetrating trauma volume per center. Expected mortality was calculated using the Trauma Mortality Prediction Model. Pearson correlation and linear mixed-effects models evaluated the association between variables and performance.

RESULTS

We identified 4,134 PTI patients treated at 596 trauma centers: 879 (21%) at Adult Level I, 608 (15%) at Adult Level II, 531 (13%) at Pediatric Level I, 320 (8%) at Pediatric Level II, and 1,796 (43%) at other centers. Primary injury mechanisms were firearm-related (58%) and cut/piercing (42%). Overall mortality was 16% and median predicted mortality was 3.6% (IQR: 1.5% - 11.2%). Among patients with thoracic firearm-related injuries, centers with lower penetrating case volume and total trauma care demonstrated significantly worse outcomes. Multivariable analysis revealed Adult Level I centers had superior outcomes compared with all other non-Level I centers. There was no difference in mortality between Pediatric and Adult Level I centers.

DISCUSSION

Adult Level I trauma center designation and annual case volume of penetrating thoracic trauma are associated with improved mortality after pediatric firearm-related thoracic injuries. Further study is needed to identify factors in higher volume centers that improve outcomes.

Standardized perioperative care reduces colorectal surgical site infection in children: A Western Pediatric Surgery Research Consortium multicenter analysis

PURPOSE

Surgical site infection (SSI) remains a significant source of patient morbidity and resource utilization in children undergoing colorectal surgery. We examined the utility of a protocolized perioperative care bundle in reducing SSI in pediatric patients undergoing colorectal surgery.

METHODS

We conducted a prospective cohort study of patients ≤18 years of age undergoing colorectal surgery at ten United States children's hospitals. Using a perioperative care protocol comprising eight elements, or "colon bundle", we divided patients into low (1-4 elements) or high (5-8 elements) compliance cohorts. Procedures involving colorectal repair or anastomosis with abdominal closure were included. Demographics and clinical outcomes were compared between low and high compliance cohorts. Compliance was compared with a retrospective cohort. The primary outcome was superficial SSI incidence at 30 days.

RESULTS

Three hundred and thirty-six patients were included in our analysis: 138 from the low compliance cohort and 198 from the high compliance cohort. Age and gender were similar between groups. Preoperative diagnosis was similar except for more patients in the high compliance cohort having inflammatory bowel disease (18.2% versus 5.8%, p<0.01). The most common procedure performed was small bowel to colorectal anastomosis. Wound classification and procedure acuity were similar between groups. Superficial SSI at 30 days occurred less frequently among the high compliance compared to the low compliance cohort (4% versus 9.7%, p = 0.036). Median postoperative length of stay and 30-day rates of readmission, reoperation, intra-abdominal abscess and anastomotic leak requiring operation were not significantly different between groups. None of the individual colon bundle elements were independently protective against superficial SSI.

CONCLUSION

Standardization of perioperative care is associated with a reduction in superficial SSI in pediatric colorectal surgery. Expansion of standardized protocols for children undergoing colorectal surgery may improve outcomes and decrease perioperative morbidity.

Postoperative respiratory complications in SARS-CoV-2 positive pediatric patients across 20 United States hospitals: A Cohort Study

INTRODUCTION

Data examining rates of postoperative complications among SARS-CoV-2 positive children are limited. The purpose of this study was to evaluate the impact of symptomatic and asymptomatic SARS-CoV-2 positive status on postoperative respiratory outcomes for children.

METHODS

This retrospective cohort study included SARS-CoV-2 positive pediatric patients across 20 hospitals who underwent general anesthesia from March to October 2020. The primary outcome was frequency of postoperative respiratory complications, including: high-flow nasal cannula/non invasive ventilation, reintubation, pneumonia, Extracorporeal Membrane Oxygenation (ECMO), and 30-day respiratory-related readmissions or emergency department (ED) visits. Univariate analyses were used to evaluate associations between patient and procedure characteristics and stratified analyses by symptoms were performed examining incidence of complications.

RESULTS

Of 266 SARS-CoV-2 positive patients, 163 (61.7%) were male, and the median age was 10 years (interquartile range 4-14). The majority of procedures were emergent or urgent (n = 214, 80.5%). The most common procedures were appendectomies (n = 78, 29.3%) and fracture repairs (n = 40,15.0%). 13 patients (4.9%) had preoperative symptoms including cough or dyspnea. 26 patients (9.8%) had postoperative respiratory complications, including 15 requiring high-flow oxygen, 8 with pneumonia, 4 requiring non invasive ventilation, 3 respiratory ED visits, and 2 respiratory readmissions. Respiratory complications were more common among symptomatic patients than asymptomatic patients (30.8% vs. 8.7%, p = 0.01). Higher ASA class and comorbidities were also associated with postoperative respiratory complications.

CONCLUSIONS

Postoperative respiratory complications are less common in asymptomatic versus symptomatic SARS-COV-2 positive children. Relaxation of COVID-19-related restrictions for time-sensitive, non urgent procedures in selected asymptomatic patients may be reasonably considered. Additionally, further research is needed to evaluate the costs and benefits of routine testing for asymptomatic patients.

Estimates of Treatable Deaths Within the First 20 Years of Life from Scaling Up Surgical Care at First-Level Hospitals in Low- and Middle-Income Countries

BACKGROUND

Surgical care is an important, yet often neglected component of child health in low- and middle-income countries (LMICs). This study examines the potential impact of scaling up surgical care at first-level hospitals in LMICs within the first 20 years of life.

METHODS

Epidemiological data from the global burden of disease 2019 Study and a counterfactual method developed for the disease control priorities; 3rd Edition were used to estimate the number of treatable deaths in the under 20 year age group if surgical care could be scaled up at first-level hospitals. Our model included three digestive diseases, four maternal and neonatal conditions, and seven common traumatic injuries.

RESULTS

An estimated 314,609 (95% UI, 239,619-402,005) deaths per year in the under 20 year age group could be averted if surgical care were scaled up at first-level hospitals in LMICs. Most of the treatable deaths are in the under-5 year age group (80.9%) and relates to improved obstetrical care and its effect on reducing neonatal encephalopathy due to birth asphyxia and trauma. Injuries are the leading cause of treatable deaths after age 5 years. Sixty-one percent of the treatable deaths occur in lower middle-income countries. Overall, scaling up surgical care at first-level hospitals could avert 5·1% of the total deaths in children and adolescents under 20 years of age in LMICs per year.

CONCLUSIONS

Improving the capacity of surgical services at first-level hospitals in LMICs has the potential to avert many deaths within the first 20 years of life.

Modified laparoscopic gastrostomy tube placement in children: Does subcutaneous suture type matter?

BACKGROUND

Laparoscopic gastrostomy tube (GT) placement carries the risk of early tube dislodgement and is often modified with absorbable subcutaneously-tunneled transabdominal tacking sutures that can aid in tube replacement. However, these buried sutures may increase the risk of surgical site infection (SSI). This study sought to evaluate SSI rates associated with different types of transabdominal tacking sutures used in modified laparoscopic GT placement.

METHODS

A single-institution, retrospective review was performed of all patients ≤18 years-old undergoing modified laparoscopic GT placement between September 2016 and March 2020. Patients were stratified into three groups by suture type used, and the primary outcome was SSI within six weeks of surgery. Demographic and perioperative data were analyzed by chi-square or Fisher's exact test.

RESULTS

A total of 113 modified laparoscopic GT placements were performed at a median age of 9 months (interquartile range 3 months to 3 years). Prophylactic antibiotic use was similar between groups. Eleven patients (10%) developed an SSI, and all were treated with antibiotics alone. No SSIs were observed with the use of poliglecaprone suture (n = 46), and higher SSI rates were observed with use of polyglactin (n = 17) and polydioxanone (n = 51) suture (18% polyglactin vs. 16% polydioxanone vs. 0% poliglecaprone, p<0.05). No differences were observed in rates of early postoperative dislodgement, leakage, or granulation tissue.

CONCLUSION

Absorbable braided and long-lasting monofilament transabdominal tacking sutures may increase risk of SSI following modified laparoscopic gastrostomy tube placement. In this cohort, the use of poliglecaprone (Monocryl) suture was associated with no SSIs and similar rates of postoperative dislodgement, leakage, and granulation tissue.

Bike Helmet Usage in the Most Disadvantaged Neighborhoods: A Focused Area for Trauma Prevention

INTRODUCTION

There is a paucity of data to describe how neighborhood socioeconomic disadvantage (NSD) correlates with childhood injuries and outcomes. This study assesses the relationship of NSD to bicycle safety and trauma outcomes among pediatric bicycle versus automobile injuries.

METHODS

Between 2008 and 2018, patients ≤18 y old with bicycle versus automobile injuries from a Level I pediatric trauma center were evaluated. Area Deprivation Index (ADI) was used to measure NSD. Patient demographics, injury, clinical data characteristics, and bike safety were analyzed. Traffic scene data from the Statewide Integrated Traffic Records System were matched to clinical records. Multivariate logistic regression was used to assess demographic characteristics related to helmet usage.

RESULTS

Among 321 patients, 84% were male with a median age of 12 y [interquartile range 9-13], and 44% were of Hispanic ethnicity. Hispanic ethnicity was greater in the most disadvantaged ADI groups (P < 0.001). Mortality occurred in two patients, and most (96%) were discharged home. Of Statewide Integrated Traffic Records System matched traffic records, 81% were at locations without a bike lane. No differences were found in GCS, intensive care unit admission, or length of stay by ADI. Hispanic ethnicity and the highest deprivation group were independently associated with lower odds of wearing a helmet (AOR 0.35, 95% confidence interval 0.1-0.9, P = 0.03; AOR 0.33 95% confidence interval 0.17-0.62; P = 0.001), while patient age and sex were unrelated to helmet usage.

CONCLUSIONS

Outcomes for bike versus auto trauma remains similar across ADI groups. However, bike helmet usage is significantly lower among Hispanic children and those from neighborhoods with greater socioeconomic disadvantage.

Integrating Traffic Safety Data with Area Deprivation Index: A Method to Better Understand the Causes of Pediatric Pedestrian Versus Automobile Collisions

BACKGROUND

The purpose of this study was to identify clinical and traffic factors that influence pediatric pedestrian versus automobile collisions (P-AC) with an emphasis on health care disparities.

METHODS

A retrospective review was performed of pediatric (≤18 years old) P-AC treated at a Level I pediatric trauma center from 2008 to 2018. Demographic, clinical, and traffic scene data were analyzed. Area Deprivation Index (ADI) was used to measure neighborhood socioeconomic disadvantage (NSD) based on home addresses. Traffic scene data from the California Statewide Integrated Traffic Records System (SWITRS) were matched to clinical records. Traffic safety was assessed by the streetlight coverage, the proximity of the collision to home addresses, and sidewalk coverage. Descriptive statistics and univariate analysis for key variables and outcomes were calculated using Kruskal-Wallis, Wilcoxon, Chi-square, or Fisher's exact tests. Statistical significance was attributed to p-values <0.05.

RESULTS

Among 770 patients, the majority were male (65%) and Hispanic (54%), with a median age of 8 years (IQR 4-12). Hispanic patients were more likely to live in more disadvantaged neighborhoods than non-Hispanic patients (67% vs. 45%, p < 0.01). There were no differences in clinical characteristics or outcomes across ADI quintiles. Using the SWITRS (N = 272), patients with more NSD were more likely injured during dark streetlight conditions (15% vs. 4% least disadvantaged; p = 0.04) and within 0.5 miles from home (p < 0.01). Pedestrian violations were common (65%). During after-school hours, 25% were pedestrian violations, compared to 12% driver violations (p = 0.02).

CONCLUSION

A larger proportion of Hispanic children injured in pedestrian versus automobile collisions lived in neighborhoods with more socioeconomic disadvantage. Hispanic ethnicity and NSD are each independently associated with P-AC. Poor streetlight conditions and close proximity to home were associated with the most socioeconomically disadvantaged neighborhoods. This research may support targeted prevention programs to improve pedestrian safety in children.

Pediatric trauma in the California-Mexico border region: Injury disparities by Area Deprivation Index

BACKGROUND

The California-Mexico border region is a high-volume trauma area with populations of widely disparate socioeconomic status. This work analyzed differences in demographics and mechanism of injury in children using the Area Deprivation Index (ADI), a composite measure of 17 markers of neighborhood socioeconomic disadvantage.

METHODS

A retrospective review was performed of pediatric patients evaluated at the regional Level I Pediatric Trauma Center between 2008 and 2018. Collected data included patient demographics and injury characteristics. Patient addresses were correlated to neighborhood disadvantage level using ADI quintiles, with a higher quintile representing greater socioeconomic disadvantage.

RESULTS

A total of 9,715 children were identified, of which 4,307 (44%) were Hispanic. Hispanic children were more likely to live in more disadvantaged neighborhoods than non-Hispanic children (p < 0.001). There were markedly different injury mechanisms in neighborhoods with greater socioeconomic disadvantage (higher ADI) compared with those with less socioeconomic disadvantage. Sports-related and nonmotorized vehicular trauma predominated in less disadvantaged neighborhoods, while higher ADI quintiles were strongly associated with pedestrian versus automobile, motorized vehicle accidents/collisions, and nonaccidental injuries (p < 0.001).

CONCLUSION

This analysis represents the first study to characterize pediatric traumatic injury patterns based upon the neighborhood ADI metric. Area Deprivation Index can be a useful resource in identifying disparities in pediatric trauma and children at increased risk for vehicular and abusive injury who may benefit from increased resource allocation, social support, and prevention programs.

Adolescent Vaping-Associated Trauma in the Western United States

INTRODUCTION

Electronic cigarettes (e-cigarettes) are handheld, battery-powered vaporizing devices. It is estimated that more than 25% of youth have used these devices recreationally. While vaping-associated lung injury is an increasingly recognized risk, little is known about the risk of traumatic injuries associated with e-cigarette malfunction.

METHODS

A multi-institutional retrospective study was performed by querying the electronic health records at nine children's hospitals. Patients who sustained traumatic injuries while vaping from January 2016 through December 2019 were identified. Patient demographics, injury characteristics, and the details of trauma management were reviewed.

RESULTS

15 children sustained traumatic injuries due to e-cigarette explosion. The median age was 17 y (range 13-18). The median injury severity score was 2 (range 1-5). Three patients reported that their injury coincided with their first vaping experience. Ten patients required hospital admission, three of whom required intensive care unit admission. Admitted patients had a median length of stay of 3 d (range 1-6). The injuries sustained were: facial burns (6), loss of multiple teeth (5), thigh and groin burns (5), hand burns (4), ocular burns (4), a radial nerve injury, a facial laceration, and a mandible fracture. Six children required operative intervention, one of whom required multiple operations for a severe hand injury.

CONCLUSIONS

In addition to vaping-associated lung injury, vaping-associated traumatic injuries are an emerging and worrisome injury pattern sustained by adolescents in the United States. This report highlights another means by which e-cigarettes pose an increasing risk to a vulnerable youth population.

Balloons for kids: Anatomic candidacy and optimal catheter size for pediatric resuscitative endovascular balloon occlusion of the aorta

BACKGROUND

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a potential adjunct in pediatric trauma patients with noncompressible truncal and pelvic hemorrhage; however, there are little data evaluating the anatomic considerations of REBOA in children. We evaluated the vascular dimensions and anatomic limitations of using REBOA in children.

METHODS

Computed tomography scans of pediatric patients performed between February 2016 and October 2019 were retrospectively reviewed by two investigators. Vascular measurements included diameters of aorta zones I and III, common iliac arteries, external iliac arteries, and common femoral arteries (CFAs), and distances between access site (CFA) and aorta zones I and III. Measurements were grouped within Broselow categories, based upon patient height. Interrater reliability for measurements was determined using intraclass correlation coefficients. Vascular dimensions were correlated with the patient's height, weight, and body mass index using linear regression analysis.

RESULTS

A total of 557 computed tomography scans met the inclusion criteria and were reviewed. Measurements of vessel diameter and distance from the CFA to aorta zones I and III were determined and grouped by Broselow category. Patient age ranged from 0 to 18 years, with a male to female ratio of 1:1. Overall interrater reliability of vessel measurements was good (average intraclass correlation coefficient, 0.90). Vessel diameter had greatest correlation with height (R2 = 0.665, aorta zone I; R2 = 0.611, aorta zone III) and poorly correlated with body mass index (R2 = 0.318 and R2 = 0.290, respectively).

CONCLUSION

This study represents the largest compilation of REBOA-related pediatric vessel diameter measurements and the first to provide data on distance between access site and balloon deployment zones. Based on our findings, the 7-Fr REBOA catheter would be appropriate for the Black, Green, and Orange Broselow categories, and a 4-Fr REBOA catheter would be warranted for Yellow, White, and Blue Broselow categories.

Tumor or Inflammatory Myofibroblastic Reaction in an Adolescent With an Abdominal Lymphatic Malformation?

We report the case of a 17-year-old male who presented with intractable nausea and vomiting. Cross-sectional imaging revealed a large retrogastric abdominal mass. Fine needle aspiration done via endoscopic ultrasound (EUS) was nondiagnostic. Exploratory laparotomy revealed a large inflammatory mass densely adherent to the stomach and retroperitoneum. Incisional biopsy frozen section revealed spindle cells, and subsequent resection of the mass with en-bloc subtotal gastrectomy with Roux-en-y gastrojejunostomy reconstruction was performed. Final pathology demonstrated a lymphatic malformation with reactive myofibroblastic proliferation. Inflammatory abdominal lymphatic malformations are especially rare and not well described in the literature. These masses may present diagnostic challenges until the specimen is sent for pathologic analysis.

Trends in Surgical Case Volume During Pacific Partnership Missions Onboard USNS Mercy

INTRODUCTION

Since 2006, the U.S. Navy has conducted six Pacific Partnership (PP) missions throughout Southeast Asia on board the U.S. Naval Ship Mercy (T-AH 19). This study describes trends in overall and surgical specialty operative volumes to better understand the burden of surgical disease treated during these humanitarian and civic assistance (HCA) operations. This information can assist medical planners and surgical leaders involved in future humanitarian missions.

MATERIALS AND METHODS

Following approval from the Naval Medical Center San Diego Institutional Review Board, a retrospective review of surgical case data was performed for the six PP missions from 2006 to 2018. Data collected included patient demographics, Current Procedural Terminology codes, and surgical specialty. The primary outcome was surgical case volume per specialty. Secondary outcomes included surgical staffing per mission and overall trends in operative volume.

RESULTS

A total of 3,826 operative procedures were performed during the study period. Mission years in which case volume for both general surgery and ophthalmology were below their respective medians were associated with the least total surgical services to host nations (HNs). The number of active duty Navy surgeons varied with each mission; however, the staffing for a PP mission generally included at least two general surgeons, one ophthalmologist, one plastic surgeon, one pediatric surgeon, one orthopedic surgeon, one otolaryngologist, one oral surgeon, one urologist, and one obstetrician-gynecologist. Case volume per surgeon was highest in 2006 (50 cases per surgeon) and decreased after 2006, reaching an all-time low during the 2018 PP mission (10 cases per surgeon). Pediatric surgery and plastic surgery had the highest average case volumes per surgeon at 58 and 46 cases per surgeon, respectively, while oromaxillofacial surgery and neurosurgery had the lowest average case volumes per surgeon at 9 and 14 cases per surgeon, respectively.

CONCLUSIONS

Operative volume on military HCA missions is greatly influenced by the priorities of the HN, the mission focus, the number of individuals from the HN that present for screening, and the availability of personnel and resources available on the hospital ship. Future mission planning should optimize general surgery and ophthalmology staffing and essential equipment, as total mission case volumes were highly dependent upon the productivity of these two specialties. Careful determination of the surgical needs of HNs should serve as a guide for the selection of subspecialists to maximize effectiveness in future military HCA missions.

Telementorship in Underway Naval Operations: Leveraging Operational Virtual Health for Tactical Combat Casualty Care

BACKGROUND

Virtual health (VH) may enhance mentorship to remote first responders. We evaluated the feasibility of synchronous bidirectional VH to mentor life-saving procedures performed by deployed novice providers.

METHODS

Video teleconferencing (VTC) was established between the USNS Mercy (T-AH 19) underway in the Pacific Ocean to Naval Medical Center San Diego using surgeon teleconsultation. The adult simulated clinical vignette included injuries following a shipboard explosion with subsequent fire. The pediatric simulated vignette included injuries that resulted from an improvised explosive device (IED) blast. Using VTC, augmented reality (AR) goggles, and airway simulation equipment, corpsmen (HMs) received visual cues to perform advanced life-saving procedures.

RESULTS

In adult scenarios, 100% of novice hospital HMs performed tasks on first attempt (n = 12). Mean time for tourniquet placement was 46 seconds (standard deviation [SD], 19 seconds); needle thoracostomy, 70 seconds (SD, 67 seconds); tube thoracostomy, 313 seconds (SD, 152 seconds); and cricothyroidotomy, 274 seconds (SD, 82 seconds). In pediatric scenarios, 100% of novice HMs performed tasks on first attempt (n = 5). Mean time for tube thoracostomy completion was 532 seconds (SD, 109 seconds).

CONCLUSION

VH can enhance the training and delivery of trauma care during prolonged field care in resource-limited settings.

Identifying risk factors for enteral access procedures in neonates with congenital diaphragmatic hernia: A novel risk-assessment score

BACKGROUND/PURPOSE

The purpose of this study was to evaluate the characteristics of neonates with congenital diaphragmatic hernia (CDH) undergoing enteral access procedures (gastrostomy or jejunostomy) during their initial hospitalization, and establish a clinical scoring system based on these characteristics.

METHODS

Data were obtained from the multicenter, multinational CDH Study Group database (CDHSG Registry) between 2007 and 2019. Patients were randomly partitioned into model-derivation and validation subsets. Weighted scores were assigned to risk factors based on their calculated β-coefficients after logistic regression.

RESULTS

Of 4537 total patients, 597 (13%) underwent gastrostomy or jejunostomy tube placement. In the derivation subset, factors independently associated with an increased risk for enteral access included oxygen requirement at 30-days, chromosomal abnormalities, gastroesophageal reflux, major cardiac anomalies, ECMO requirement, liver herniation, and increased defect size. Based on the devised scoring system, patients could be stratified into very low (0-4 points; <10% risk), low (5-6 points; 10-20% risk), intermediate (7-9 points; 30-60% risk), and high risk (≥10 points; 70% risk) groups for enteral access.

CONCLUSION

This study identifies risk factors associated with enteral access procedures in neonates with congenital diaphragmatic hernia and establishes a novel scoring system that may be used to guide clinical decision making in those with poor oral feeding.

Extremes of age are associated with differences in the expression of selected pattern recognition receptor genes and ACE2, the receptor for SARS-CoV-2: implications for the epidemiology of COVID-19 disease

Background

Older aged adults and those with pre-existing conditions are at highest risk for severe COVID-19 associated outcomes.

Methods

Using a large dataset of genome-wide RNA-seq profiles derived from human dermal fibroblasts (GSE113957) we investigated whether age affects the expression of pattern recognition receptor (PRR) genes and ACE2, the receptor for SARS-CoV-2.

Results

Extremes of age are associated with increased expression of selected PRR genes, ACE2 and four genes that encode proteins that have been shown to interact with SAR2-CoV-2 proteins.

Conclusions

Assessment of PRR expression might provide a strategy for stratifying the risk of severe COVID-19 disease at both the individual and population levels.

Patience is a virtue: Multiple preoperative visits are associated with decreased recurrence in pediatric pilonidal disease

BACKGROUND/PURPOSE

This study aimed to compare preoperative management strategies for patients undergoing trephination for pilonidal disease and evaluate risk factors for recurrence.

METHODS

A retrospective review was performed of children undergoing index surgical treatment with trephination for pilonidal disease between September 2017 and April 2019. Intraoperative and postoperative management were standardized. Demographic and perioperative data were collected and analyzed.

RESULTS

One-hundred twenty patients were identified with a median follow-up time of 7.5 months (interquartile range 4.1-13.2 months). Overall, 24 (20%) patients had a postoperative recurrence of pilonidal disease. Patients with multiple preoperative surgery clinic visits were less likely to have recurrent disease compared to those seen only once preoperatively (11% vs 26%, p = 0.040). Compared to patients without recurrence, those who recurred went to the operating room sooner from the time of initial surgical consultation (32 days vs 54 days, p < 0.001). Perioperative antibiotics, history of acute infection, and prior drainage procedures were not risk factors for recurrence.

CONCLUSIONS

Multiple preoperative clinic visits are associated with a lower recurrence rate in children undergoing trephination for pilonidal disease. An increased duration of preoperative medical management may be responsible for this finding. Prospective study is needed to confirm these findings and identify additional factors that influence recurrence.

An Analysis of Essential Pediatric Surgical Cases Encountered During a Decade of Large-Scale Military Humanitarian Aid Missions

INTRODUCTION

Disease Control Priorities, 3rd Edition (DCP3) is an evidence-based, published resource that outlines essential procedures recommended for developing health care systems. These systems must consider various populations and the incidence of certain surgical conditions that require treatment. In relation to pediatric patients, the prevalence of certain surgical conditions encountered remains unclear in several low- and middle-income countries. Over the past 15 years, the USNS Mercy, one of the U.S. Navy's large hospital ships, has led the Pacific Partnership missions, which provide large-scale humanitarian aid throughout Southeast Asia. The data collected during these missions provide an opportunity to analyze the scope of pediatric operations performed in resource-limited countries. This analysis may assist in future planning for specific needs during military humanitarian missions.

MATERIALS AND METHODS

Surgical case data were prospectively collected during the six Pacific Partnership missions from 2006 to 2018. Demographic data were analyzed for all patients ≤8 years of age who underwent an operation. These data were retrospectively reviewed and all case logs were categorized by mission year, procedure-type, and host nation. Operations were classified based on 44 essential operations delineated in DCP3. Primary outcome was incidence of DCP3 essential operations. Secondary outcomes were perioperative complications. Standard statistical methods were performed for descriptive analysis.

RESULTS

A total of 3,209 major and minor operations were performed during 24 port visits in nine countries. Pediatric cases represented 1,117 (38%) of these procedures. Pediatric surgeons performed 291 (26%) of these cases. Based on DCP3 criteria, 789 pediatric operations (71%) were considered essential procedures. The most common DCP3-aligned procedures were cleft lip repair (432, 57%), hernia repair (207, 27%), and hydrocelectomy (60, 8%). Operative volume for pediatric surgery was highest during the 2008 mission (522 cases), when two pediatric surgeons were deployed, and lowest during the 2018 mission (five cases), when the mission focus was on education rather than surgical procedures and lack of pediatric cases referred by the host nation. Overall complication rate for pediatric cases was 1%.

CONCLUSIONS

This study represents the largest known analysis of military humanitarian assistance. Pediatric operations represented over one-third of the surgical volume during Pacific Partnership missions from 2006 to 2018. The majority of cases were DCP3-aligned and associated with a low complication rate. Future humanitarian aid missions and host nations should allocate appropriate medical and educational resources to treat DCP3 pediatric surgical diseases in low- and middle-income countries to support long-term capacity building while maintaining optimal surgical outcomes.

Patient-oriented online resources in pediatric surgery: Are we failing the readability test?

BACKGROUND

The study aim was to evaluate the readability of patient-oriented resources in pediatric surgery from children's hospitals in the US.

METHODS

The websites of 30 children's hospitals were evaluated for information on 10 common pediatric surgical procedures. Hospitals of varying characteristics including bed number, geographic location and ACS Children's Surgery Verification (CSV) were selected for the study. Readability scores were calculated using validated algorithms, and text was assigned an overall grade level.

RESULTS

Of 195 patient-oriented resources identified, only three (2%) were written at or below the recommended sixth grade level. Larger hospitals provided patient information at a higher grade level than medium and smaller sized centers (10.7 vs 9.3 vs 9.0 respectively, p < 0.001). Hospital size also correlated with availability of information, with large and medium sized hospitals having information more often. Hospitals with ACS CSV had information available more often, and written at a lower grade level, compared to nonverified centers (78% vs 62%, p = 0.023; 9.0 vs 10.0, p = 0.013).

CONCLUSION

Most hospital provided patient-oriented resources in pediatric surgery are written at a grade level well above the national guidelines. Centers with ACS CSV status have improved availability and readability of this material, while larger hospitals have improved availability, but decreased readability.

Trephination versus wide excision for the treatment of pediatric pilonidal disease

BACKGROUND/PURPOSE

To evaluate outcomes of trephination compared to wide excision in children undergoing initial surgical treatment of pilonidal disease.

METHODS

A retrospective review was conducted of patients undergoing initial pilonidal excision between September 2017 and September 2018. Operations were categorized as either trephination or wide excision via an open or closed-wound technique. Outcomes were evaluated and data analyzed by chi-squared and one-way ANOVA tests.

RESULTS

One-hundred and five patients were identified, with a mean follow-up of 4.6 months. Trephination was performed in 57% of patients, and of the remaining patients undergoing wide excision, 62% of wounds were left open. There were no demographic differences among the three groups. Compared to both the open and closed techniques, trephination was associated with fewer wound complications (17% vs 29% vs 3%, respectively, p = 0.006), and postoperative visits (4.4 vs 2.4 vs 1.4, respectively, p < 0.001). There was no difference in recurrence rates among groups.

CONCLUSION

Trephination for pilonidal disease in pediatric patients is associated with a lower wound complication rate and fewer postoperative visits compared to wide excision. Recurrence rates are similar among the various surgical methods. Further prospective study would be useful to describe long-term outcomes of patients undergoing trephination for pilonidal disease.

Practical Bioethics for the Humanitarian Surgeon: The Development, Implementation and Assessment of an Ethics Curriculum for Residents Participating in Humanitarian Missions

BACKGROUND

Humanitarian surgeons face many ethical challenges. Despite increasing resident participation during humanitarian activities, minimal literature exists describing premission ethics training.

METHODS

A systematic literature review was conducted to identify publications on humanitarian surgery. A 3-tiered review was performed assessing for ethical conflicts and guidelines. A Humanitarian Ethics Curriculum (HEC) was developed based on these findings and administered to residents prior to a humanitarian mission. Postmission essays were assigned to describe an ethical dilemma they encountered. The HEC's value was evaluated by identifying the ACGME core competencies represented in the essays.

RESULTS

49 eligible publications were identified. Several areas of consensus were found. Controversies identified included: trainee involvement, surgical innovation, and operating on patients with dismal prognosis. All residents stated that the HEC was vital. 61% of ethical dilemmas involved surgical patients. Core competencies emphasized included systems-based practice, patient care, professionalism, interpersonal/communication skills, and medical knowledge.

CONCLUSIONS

There is consensus regarding ethical principles that surgeons should follow during humanitarian activities. However, areas of controversy persist. Premission HEC should be administered to residents participating in humanitarian missions.

Evaluating surgical outcomes in pediatric extremity vascular trauma

BACKGROUND

The purpose of this study was to evaluate the epidemiology and management of pediatric vascular extremity trauma to assess injury patterns and other factors that may contribute to poor outcomes.

METHODS

Using the California Office of Statewide Health Planning and Development discharge database, we identified pediatric patients with extremity arterial trauma admitted to acute-care hospitals from 2007 to 2014. Demographics, management patterns, and outcomes were collected and analyzed.

RESULTS

A total of 775 patients were treated for an extremity arterial injury. Overall, 40% were admitted to pediatric trauma centers and 39% to adult trauma centers. Management was predominantly by open surgical repair. Injury to the common femoral artery was associated with mortality (Hazard Ratio 3.9; 95% CI 1.1-14.5; p < 0.05). Popliteal artery injuries (Odds Ratio [OR] 4.8; 95% CI 1.2-19.9; p < 0.05) and anterior tibial artery injuries (OR 7.1; 95% CI 1.4-37.3; p < 0.05) had an increased risk of amputation. There was no difference in amputation or mortality rates by hospital category.

CONCLUSIONS

Pediatric extremity arterial injuries are rare. In California, outcomes are similar by hospital type. Common femoral artery injuries are associated with an increased risk of mortality, while popliteal and anterior tibial artery injuries are associated with an increased risk of amputation.

Premenarchal patients present differently: A twist on the typical patient presenting with ovarian torsion

BACKGROUND/PURPOSE

The aim of this study was to characterize differences between pre- and postmenarchal females with ovarian torsion.

METHODS

A single-center review was conducted of all nonneonatal pediatric patients with ovarian torsion from 2011 to 2018. Clinical data were compared between pre- and postmenarchal patients.

RESULTS

One hundred and twenty-seven patients were identified, and 25% were premenarchal. Premenarchal patients were more likely to have a delay in diagnosis (38% vs 20%, p = 0.042), develop ovarian necrosis (34% vs 17%, p = 0.036), and present without an associated adnexal mass (44% vs 0%, p < 0.001). All patients without a mass (n = 14) were premenarchal and presented with ovarian asymmetry. Patients without an associated mass underwent oophoropexy in the majority of cases. There were no differences in postoperative complication or recurrence rates between groups.

CONCLUSION

Premenarchal females with ovarian torsion can present differently than females postmenarche and often have a delay in diagnosis. Premenarchal females are more likely to undergo torsion without an associated adnexal mass and are at higher risk for ovarian necrosis. Oophoropexy is an appropriate treatment in the absence of an adnexal mass. A high-index of suspicion for ovarian torsion should be maintained for premenarchal females presenting with abdominal pain and an otherwise negative workup.

Attrition Rate in Military General Surgery GME and Effect on Quality of Military Programs

INTRODUCTION

The attrition rate in civilian general surgery Graduate Medical Education (GME) is estimated at 20%, while estimates of attrition in military general surgery (MGS) GME programs using the same methodology are nearly twice that. We sought to identify the true attrition rate in MGS GME, identify factors influencing attrition, and examine the relationship between attrition and quality of MGS GME.

METHODS

Deidentified data were collected on categorical general surgery residents matriculating from 2010 to 2013 from all 12 MGS residency programs. Information gathered included gender, medical degree, marital status, location of program, presence of a military-related interruption in training, and age at start of the categorical contract. For those who did not graduate, data on postgraduate year at time of attrition, reasons for attrition, and deficiencies in core competencies were solicited. To assess the effect of true attrition rate on graduate performance, we compared the published 5-year American Board of Surgery qualifying exam/certifying exam first time pass rates between military and civilian programs.

RESULTS

One hundred eighty-four categorical residents matriculated from 2010 to 2013. Fifty six (31.5 %) were women, 151 (62.1%) were MD's, 103 (56%) were married, 172 (93.5%) were less than 35 years old, and 33 (17.9%) had a military-related interruption in training. Nineteen individuals left residency prior to graduation (15 resigned, 2 resigned in lieu of termination, 2 terminated) for an overall attrition rate of 10.3%. The most common year for attrition was PGY-3 (31.6%) and most common reason for resignation was changing to a different subspecialty (73.3%). Men and women had equal attrition rates (10.3%), and there was no meaningful difference between MD's and DO's (9.9% vs 12.1%, p = 0.71) or region of training (10.6% East vs 9.1% West, p = 0.73). However, those who were not married, had a militarily mandated interruption in training and started their categorical training over the age of 35 had higher attrition rates (married 5.6%, not married 15%, p = 0.04, interruption 16% vs no interruption 9%, p = 0.1; Age ≥ 35 33.3% vs age < 35 6.7%, p < 0.01). Comparison of American Board of Surgery (ABS) first time pass rates over a similar time period showed that military programs performed statistically discernibly better than civilian programs (82% ± 12 vs 75% ± 13, p = 0.047).

CONCLUSIONS

Previous used methodology over estimates the attrition rate in MGS GME. The lower rate in MGS programs results in a high level of graduate performance as measured by ABS pass rates. Interruption in training and especially marital status and age ≥ 35 appear to be potential predictors of attrition. Components of MGS GME training and selection processes might inform efforts to reduce attrition and improve performance in civilian surgical GME.

The History of Surgical Staplers: A Combination of Hungarian, Russian, and American Innovation

Since their development in 1908, surgical staplers have been used as a method of "mechanical suturing" in efforts to divide hollow viscera and create anastomoses in an efficient and sterile manner. The concept for the surgical stapler was first developed by Humér Hultl, a Hungarian professor and surgeon, and designed by Victor Fischer, a Hungarian businessman and designer of surgical instruments. The design was highly acclaimed; however, it was bulky, cumbersome, and expensive to manufacture. In 1920, Aladár Petz, a student of Hultl, incorporated two innovations to the Fischer-Hultl stapler to create a more lightweight model, which was named the Petz clamp. In 1934, Friedrich of Ulm designed what would be the predecessor to the modern-day linear stapler. In the 1950s, Russian and American staplers began to emerge. Throughout the 1960s, a variety of stapling instruments were developed in the United States, manufactured by the United States Surgical Corporation. In the 1970s, Johnson & Johnson Ethicon brand joined the market. The United States Surgical Corporation was later bought by Tyco Healthcare and became Covidien in 2007. Through the collaboration of Felicien Steichen, Mark Ravitch, and Leon Hirsch, surgical staplers were further modified to incorporate interchangeable cartridges with various designs. With the advent of minimally invasive surgery began production of laparoscopic surgical staplers. Since its inception, the surgical stapler has provided a means to efficiently create safe and effective visceral and vascular anastomoses. The surgical stapler design continues to evolve while still maintaining the basic principles that were implemented in the original design.

Abdominoscrotal hydrocele (ASH) is an uncommon condition characterized by a fluid-filled mass with inguinoscrotal and abdominal components. Controversy exists regarding the best management. We conducted a systematic review of the literature with special interest in presentation, management and outcomes.

METHODS

A search was conducted of the MEDLINE/PubMed, Embase, Ovid, Web of Science and Scopus databases. Two authors independently extracted data and assessed the risk of bias in each study.

RESULTS

We found 18 case series that met selection criteria, describing 116 patients with 146 hydroceles. Unilateral ASH was found in 59% of cases with almost even distribution between left and right-sided hydroceles. Ipsilateral undescended testicle, testicular dysmorphism, and contralateral pathology (inguinal hernia) often accompanied ASH. Management was always surgical. The most common approaches were inguinal (67.2%), combined laparoscopic + inguinal (11.2%), and scrotal (10.3%). Complications were poorly reported, but were generally minor. There were a decreased number of complications with the scrotal approach because of avoidance of a difficult inguinal dissection.

CONCLUSIONS

ASH is a rare entity treated most commonly via an inguinal approach. However, consideration should be given to combining with an extraperitoneal or laparoscopic approach given coexisting pathology, or to the scrotal approach for reducing morbidity.
