Cervical spine computed tomography (CSCT) scans are used to evaluate cervical spine traumatic injuries; however, recent evidence demonstrates that adult trauma centers (ATCs) overutilize CSCT when evaluating adolescent patients. This leads to unnecessary radiation exposure. The aim of this study is to review a level 1 ATC's use of CSCT in the adolescent blunt trauma population.A retrospective chart review was conducted of a level 1 ATC's trauma database. Blunt trauma patients between the ages of 11 and 18 who receive a CSCT between January 2015 to December 2019 were included. The primary outcome was the prevalence of positive findings on CSCT scans. Data were analyzed using Fischer-Exact analysis and multivariate logistic regression where appropriate.Three-hundred thirty-seven of 546 (61.7%) adolescent blunt trauma patients received CSCT. Of those, 68.2% (230) were male; the mean age was 16.6 ± 1.0 y old. Twenty-eight patients (8.3%) had a positive finding on CSCT. All patients with a positive CSCT failed the National Emergency X-Radiography Utilization study (NEXUS) criteria while 123 patients (36.5%) with a negative CSCT met NEXUS criteria.CSCT was overutilized in our trauma center. There is a low positive CSCT scan rate among adolescent patients, which aligns with the current literature. All patients with positive CSCT passed NEXUS criteria suggesting that a quality improvement project focusing on the use of the NEXUS criteria to assess the risk of cervical spine injury could potentially reduce the use of CSCT scans by nearly 40%.

The algorithm for evaluating adolescent patients with blunt trauma includes abdominal pelvic CT (APCT). The aim of this study is to evaluate the utility of APCT in this context.We performed a retrospective review of adolescent (11 to 18 years of age) blunt trauma patients at an urban adult level 1 trauma center from January 2015 to December 2019. The primary outcome was the prevalence of positive findings on APCT scan. Additionally, clinical risk factors concerning for intra-abdominal injury were analyzed.There were 546 patients evaluated for blunt trauma and the prevalence of APCT within the population was 59.3% (95% CI 54.2%-64.9%). Of the patients who received APCT, 123 (37.9%) had positive findings on APCT. Only 25 patients (7.7% of those who underwent APCT) required abdominal surgery while 40 patients (12.3%) had intraabdominal injury that did not require surgery. Risk factors were present in 100% of patients with intraabdominal injury and absent in 28.7% of patients without intraabdominal injury. Abnormal abdominal exam, abnormal FAST, positive chest x-ray and elevated transaminases were independently associated with intraabdominal injury.Our study found that adolescent blunt trauma patients treated at our trauma center had a higher rate of APCT usage, but a comparable rate of positive findings when compared with the most recent literature. Future studies should focus on reducing the number of patients who undergo APCT despite an absence of clinical risk factors.

The role of contrast study after traumatic gastric repair, continues to be controversial. To that end, we aim to review the incidence, outcomes, and risk factors of patients undergoing contrast study after traumatic gastric repair.This was a retrospective review of all trauma patients admitted to a level 1 trauma center that sustained gastric injuries with subsequent repair between 2011 and 2018. Demographics, surgical interventions, complications, and clinical outcomes were evaluated. Statistical analysis included Chi-square/Fisher exact univariate analysis and multivariate logistic regression analysis with a 5% significance level.A total of 233 patients received a gastric repair, of whom 49 (21%) had a contrast study performed. Out of 49 patients with a contrast study, one was found to have a gastric leak. Mean time to contrast study was 6.3 ± 2.7 days. There was no statistically significant difference in post-operative complications between non-contrast and contrast study groups. Multivariate logistic regression analysis demonstrated a lack of statistical significance in clinical risk factors that would lead to obtaining a contrast study.Gastric leak after repair is rare and there is no statistically significant difference in clinical outcomes when comparing patients who underwent contrast study to those who did not. Routine contrast study after traumatic gastric repair may not be necessary and further evidence is warranted to determine the risk factors for a selective contrast study.

In health care, second victims are traumatized clinicians involved in unanticipated or untoward patient events. Programs that address second victim syndrome are sparse and its diagnosis often goes unrecognized. Consistently, literature has identified gaps in support resources, leading to compromised patient care and provider health. This project evaluates the need for second victim resources in trauma care providers at a tertiary public level 1 trauma hospital by electronically implementing a validated second victim survey over 5 weeks. Our results illustrate that second victim syndrome is prevalent among 57.1% of trauma care providers, of which 22.9% agree that second victim syndrome results in some form of undesirable work intentions.

Screening, brief intervention, and referral to treatment (SBIRT) is an intervention originally developed to prevent and deter substance abuse. Adaptation of the SBIRT model to prevent post-traumatic stress disorder (PTSD) may potentially reduce acute stress symptoms after traumatic injury. We conducted a prospective randomized control study of adult patients admitted for gunshot wounds. Patients were randomized to intervention (INT) vs. treatment as usual (TAU) groups. INT received the newly developed SBIRT Intervention for Trauma Patients (SITP)—a 15-minute session with elements of cognitive behavioral therapy techniques. SITP took place during the index hospitalization; both groups had followup at 30 and 90 days at which time a validated PTSD screening tool, PCL-5, was administered. Most of the 46 participants were young (mean age = 30.5y), male (91.3%), and black (86.9%). At three-month follow-up, SBIRT and TAU patients had similar physical healing scores but the SBIRT arm showed reductions in PTSD symptoms.

Risks of intimate partner violence (IPV) escalated during the COVID-19 pandemic given mitigation measures, socioeconomic hardships, and isolation concerns. The objective of this study was to explore the impact of COVID-19 on the incidence of IPV. We conducted an interrupted time series analysis for IPV incidence at a single level 1 trauma center located in the United States. IPV cases were identified by triangulation of institutional data sources. There were 4,624 traumatic injuries of which 292 (6.3%) were due to IPV. IPV-related injury admissions increased 17% in the weeks following the COVID lockdown (RR = 1.17; 95% CI: 1.16, 1.19). Over a quarter of victims (27.4%) were male. Compared to before COVID, victims of IPV during the pandemic were younger (p = .04); no difference in mechanism or severity of injury was found. Our results suggest an ongoing need for universal IPV screening during health emergencies to avoid missed opportunities for IPV detection and referral to support services.

Repair of penetrating retrohepatic inferior vena cava (IVC) injuries continues to challenge trauma surgeons due to difficulty in accessing the injury, hemorrhage prior to the repair, and associated high mortality rates. Complication by suprahepatic vena cava injuries portends an increased risk of an unfavorable outcome. Over time, overall survival has been relatively unchanged, and the morbidity and mortality associated with these injuries continue to be very high. First proposed by Shrock et al. in 1968, atriocaval shunt placement remains the gold standard approach for the temporary bypass of these lesions by controlling bleeding from the retrohepatic IVC to allow time for repair prior to exsanguination and death. Despite familiarity with this management strategy for decades, these injuries remain infrequent but continue to have poor survival due to their complexity. There are only rare examples of the use of this approach resulting in successful discharge from the hospital. We present a case report of survival after the successful deployment of an atriocaval shunt in a patient who sustained multiple gunshot wounds to his right thoraco-abdomen, left chest, and upper and lower extremities. He ultimately survived to discharge from the hospital. We provide a brief review of the current literature and propose future approaches to repairs of juxtahepatic IVC injuries.

Background The objective of our study is to compare the predicted hospital admission disposition based on the level of risk as determined by the modified Trauma-Specific Frailty Index (mTSFI) score with those determined by arbitrary decisions made based on the Emergency Severity Index (ESI) severity level. Methods We surveyed 100 trauma patients ages 50 and older, admitted to a level 1 trauma center between April 2019 and July 2019. We retrospectively reviewed the hospital admission disposition of each patient under the ESI, which was then compared to the mTSFI-predicted hospital admission disposition. The mTSFI scores were calculated by surveying each patient. Statistical analysis was performed to identify any statistical significance of concordance and discordance when comparing the mTSFI and ESI. Results The average age was 57.6 ± 4.2 years old in the non-geriatric group vs 76.3 ± 7.3 years old in the geriatric group. There was a male predominance in both groups (61% vs 69.5%). The mTSFI identified a higher percentage of triage discordance in the non-geriatric group (73%) compared to the geriatric cohort (53%) (95% difference CI, [39.6-40], P = .05). Discussion Non-geriatric patients have higher recorded rate of frailty than previously recognized and screening should begin at age 50, not 65. The mTSFI may be an effective tool to appropriately triage adult trauma patients at increased risk due to frailty and may reduce in-hospital complications.

ObjectivesUsing rectal contrast computed tomography (CT) to identify traumatic colorectal injuries has become commonplace; however, these injuries remain relatively infrequent findings on CTs obtained for penetrating back and flank trauma. We conducted a meta-analysis to ascertain the efficacy of rectal contrast CT in identifying such injuries in victims penetrating injuries.MethodsPubMed and Embase were queried for relevant articles between 1974 and 2022. Review articles, case studies, and non-English manuscripts were excluded. Studies without descriptive CT and operative findings were excluded. Positive scans refer to rectal contrast extravasation. Sensitivity and specificity of rectal contrast CT scans were calculated with aggregated CT findings that were cross-referenced with laparotomy findings.ResultsOnly 8 manuscripts representing 506 patients quantified colorectal injuries and specified patients with rectal contrast extravasation. Seven patients with true colorectal injuries had no contrast extravasation on CT. There was one true positive scan. Another scan identified contrast extravasation, but laparotomy revealed no colorectal injury. Rectal contrast had sensitivity of 12.5%, specificity 99.8%, positive predictive value (PPV) 50%, negative predictive value (NPV) 99%, and a false negative rate of 88% in identifying colonic injuries.DiscussionThe summation of 8 manuscripts suggest that the addition of rectal contrast in identifying colonic and rectal injuries may be of limited utility given its poor sensitivity and may be unnecessary. In its absence, subtle clues such as hematomas, extraluminal air, IV-dye extravasation, and trajectory may be additional indicators of injury. Further investigations are required to demonstrate a true benefit for the addition of rectal contrast.

This study sought to determine the contribution of self-inflicted injury-related deaths to local organ donation rates and analyze contributing factors.A retrospective review of adult patients with traumatic self-inflicted injuries was performed at a Level I trauma center from 2013 to 2017. Data were obtained from the institutional trauma registry and cross-referenced with the local organ procurement organization (OPO). Referral rates were analyzed and outcomes, demographics and injury characteristics were compared between patients who underwent donation versus those who did not.142 adult patients presented with traumatic self-inflicted injury, and 100 (70.4%) had referral calls made to the local OPO. These patients were predominantly male (83%), and gunshot injuries accounted for 75% of all mechanisms. Sixty-four percent had organ referrals versus tissue referrals (34%), and 17 (26.6%) of those patients went on to donate. The median number of organs procured was 4 [IQR 0-5]. In multivariate analysis, for each year increase in age, patients were less likely to have an organ referral (OR = .96 [95% CI .93-.99]; p = .0134) and less likely to undergo donation (OR = .95 [95% CI .90-.99]; p = .0308).Self-inflicted injury, though tragic, may provide a significant contribution to the limited organ donor registry.

There are limited data comparing the severity of traumatic adrenal injury (TAI) and the need for interventions, such as transfusions, hospitalization, or incidence of adrenal insufficiency (AI) and other clinical outcomes. The aim of this study was to analyze the relationship between the grade of TAI and the need for subsequent intervention and clinical outcomes following the injury.After obtaining Institutional Review Board approval, our trauma registry was queried for patients with TAI between 2009 and 2017. Contrast-enhanced computed tomography (CT) examinations of the abdomen and pelvis were evaluated by a board-certified radiologist with subspecialty expertise in abdominal and trauma imaging, and adrenal injuries were classified as either low grade (American Association for the Surgery of Trauma (AAST) grade I-III) or high grade (AAST grade IV-V). Patients without initial contrast-enhanced CT imaging and those with indeterminate imaging findings on initial CT were excluded.A total of 129 patients with 149 TAI were included. Eight-six patients demonstrated low-grade injuries and 43 high grade. Age, gender, and Injury Severity Score (ISS) were not statistically different between the groups. There was an increased number of major vascular injuries in the low-grade vs. high-grade group (23% vs. 5%, p 0.01). No patient required transfusions or laparotomy for control of adrenal hemorrhage. There was no statistical difference in hospital length of stay (LOS), ventilator days, or mortality. Low-grade adrenal injuries were, however, associated with shorter ICU LOS (10 days vs. 16 days, p = 0.03).The need for interventions and clinical outcomes between the low-grade and high-grade groups was similar. These results suggest that, regardless of the TAI grade, treatment should be based on a holistic clinical assessment and less focused on specific interventions directed at addressing the adrenal injury.

This study investigated the impact of COVID-19 infection on hospitalized trauma patients.A retrospective review of hospitalized trauma patients at a level I trauma center was performed from March-December 2020. Data pertaining to patient demographics, presentation and hospital course was compared between COVID positive and negative trauma patients.There were 4,912 patients and 179 (3.64%) were COVID-19 positive. Demographics and clinical presentation did not differ significantly between those with and without concomitant COVID-19. However, COVID positive trauma patients had higher rates of acute kidney injury (p = 0.016), sepsis (p = 0.016), unplanned intubation (p = 0.002) and unplanned return to the ICU (p = 0.01). The COVID positive cohort also had longer hospital stays (p 0.01) with no significant difference in mortality.In the setting of an ongoing pandemic, awareness of the complications COVID positive trauma patients are predisposed to is important for providers.

Background Firearm-related injury (FRI) became the leading cause of death among children/adolescents in 2019. Purpose This study sought to determine changes over time in the population of adolescents affected by FRI in Atlanta, Georgia, such that high risk cohorts could be identified. Research Design City-wide retrospective cohort review. Study Sample Adolescent victims (age 11-21 years of age) of FRI, defined by ICD9/10 codes, in Atlanta, Georgia. Data Analysis Descriptive, multivariate and time series analysis. Results There were 1,453 adolescent FRI victims in this time period, predominantly Black (86%) and male (86.6%). Unintentional injury was higher among ages 11-14 years (43.1%) compared to 15-17 years (10.2%) and 18-21 years (9.3%) (P < .01). FRI affecting females increased at a rate of 8.1 injuries/year (P < .01), and unintentional injuries increased at by 7.6/year (P < .01). Mortality declined from 16% in 2016 to 7.7% in 2021. Conclusion Our data provides evidence for firearm policy reform. Interventions should target prevention of intentional injury among AQ4 females and seek to reverse the trend in unintentional injuries.

Background Guidelines developed by the Pediatric Emergency Care Applied Research Network (PECARN) exist to reserve the use of head CT for pediatric patients with a high risk of head injury. However, CTs are still being overutilized especially at adult trauma centers. The aim of our study was to review our use of head CTs in adolescent blunt trauma patients. Materials and Methods Patients aged 11-18 who underwent head CT scans from 2016 to 2019 at our urban level 1 adult trauma center were included. Data was collected via electronic medical record and analyzed through retrospective chart review. Results Of the 285 patients requiring a head CT, 205 had a negative head CT (NHCT) and 80 patients had a positive head CT (PHCT). There was no difference in age, gender, race, and trauma mechanism between the groups. The PHCT group was found to be with a statistically significant higher likelihood of the Glasgow Coma Scale (GCS) < 15 (65% vs 23%; P < .01), abnormal head exam (70% vs 25%; P < .01), and loss of consciousness (85% vs 54%; P < .01) compared to the NHCT group. There were 44 patients who had low risk of head injury, based on the PECARN guidelines, and received a head CT. None of the patients had a positive head CT. Conclusion Our study suggests that reinforcement of the PECARN guidelines should occur for ordering head CTs in adolescent blunt trauma patients. Future prospective studies are needed to validate the use of PECARN head CT guidelines in this patient population.

Preoperative testing to assess the physiologic impact of pectus excavatum is sometimes ordered to meet third-party payor preauthorization requirements. This study describes the utility of physiologic testing prior to minimally invasive repair of pectus excavatum (MIRPE).We retrospectively reviewed patients that underwent MIRPE from 1/2012-7/2016 at two academic children's hospitals. Data collected included demographics, insurance, Haller Index (HI), pulmonary function tests (PFTs) and echocardiograms (ECHO) obtained, and preauthorization denials.A total of 360 patients (mean age 15.7 ± 2.0 years; mean HI 4.5 ± 1.5) underwent MIRPE (Hospital 1: 189, Hospital 2: 171). Commercial insurers covered 84% of patients. Hospital 1 obtained more frequent preoperative testing (PFTs: 73% vs 6%, p 0.0001). Overall, 72% of PFTs were normal with abnormal studies limited to mild findings. Similarly, 85% of ECHOs were normal. Third-party payors more frequently denied preauthorization for MIRPE at Hospital 2 (11% vs. 5%, p = 0.03).More frequent preoperative testing may decrease initial preauthorization denials for MIRPE; however, this increased utilization of resources may not be necessary as the majority of test results are normal.

Introduction The objective of this study was to evaluate the necessity of repeat imaging after an initial chest radiograph (CXR) following minimally invasive repair of pectus excavatum (MIRPE). Materials and Methods A retrospective review was performed on patients who underwent MIRPE from January 2012 to July 2016 at two academic children's hospitals. Data collected included demographics, severity of pectus defect (Haller index [HI]), utilization of CXRs, outpatient follow-up, and clinical outcomes. Results A total of 360 patients (171 at Hospital 1 and 189 at Hospital 2) underwent MIRPE. Median age was 15.6 years and 84% were males. The median HI was 4.0. Median postoperative hospital length of stay was 4.2 days and median time to bar removal was 34 months. There was significant variation in postoperative imaging between the hospitals, including frequency of immediate postoperative CXR, total number of CXRs during hospitalization, and number of postoperative outpatient CXRs prior to bar removal. However, there was no significant difference in outcomes between the hospitals, including postoperative pneumothorax, postoperative chest tube placement, and complications. Conclusion These data suggest that increased repetitive imaging after an initial postoperative CXR does not affect clinical outcomes and may not be necessary after MIRPE.

The vertical transumbilical incision (TU) technique during neonatal abdominal exploration involves dissection and ligation of umbilical vessels, which allow access to all quadrants of the abdomen and complete bowel evisceration with minimal violation to the anterior abdominal wall. We compared patient characteristics and outcomes for neonates undergoing TU with standard transverse exploration.A single-center retrospective review of neonates who underwent abdominal exploration between January 2010 and September 2015 was conducted after obtaining Institutional Review Board approval. Data included patient demographics, indication for operative intervention, operative details, complications, including incisional hernias, and long-term outcomes.There were 88 neonates under 4 months of age who underwent abdominal exploration, with a median age of 5.5 ± 17 days and a median gestational age of 32.8 ± 16 weeks. Exploration was emergent in 38 patients (43%) and 49 (56%) required ostomy formation. A transverse incision (TV) was used in 30 patients and a TU in 58 patients. Both groups had similar postoperative complication rates; 27 (47%) in the TU group and 11 (36%) in the TV group, P = .51. Median length of follow-up in the TU group was 5.1 ± 18 months and 6.2 ± 16 months in the TV group, P = .48. The TU group had 4 incisional/umbilical hernias (7%), none have required repair.TUs for abdominal explorations in neonates have similar outcomes as the standard TV while preserving the integrity of the anterior abdominal wall.

Children with single ventricle physiology (SVP) have been shown to have a high morbidity and mortality after non-cardiac surgical procedures. Elective circumcision is one of the most common pediatric operations with low morbidity and mortality. The purpose of our study was to review our institutional experience with SVP children undergoing circumcisions to determine peri-operative course and outcomes. We performed a retrospective review of children with SVP who underwent an elective circumcision from 2000 to 2017. Children with non-single ventricle physiology or children undergoing circumcision in combination with another case were excluded. Demographics, surgical characteristics, and outcomes were analyzed. Descriptive statistics were performed, all medians were reported with interquartile range. 15 males underwent elective circumcision with a median age at the time of surgery of 1.13 (1.03, 1.38) years. Eighty-four percent underwent their circumcision after their 2nd stage cardiac operation. Most common operative indication was uncomplicated phimosis. Median operative time was 20 (16, 27) mins. Median total length of stay was 229 (185, 242) mins with no admissions. Post-operative complications included two (16%) hematomas with one requiring surgical intervention. There were no deaths. Children with SVP who undergo elective circumcision may have a higher risk of bleeding.

Our objective was to increase ultrasound reliability for diagnosing appendicitis in an academic children's hospital emergency department (ED) through a multidisciplinary quality improvement initiative.A retrospective review of ultrasound use in patients diagnosed with appendicitis in our ED from 1/1/2011 to 6/30/2014 established a baseline cohort. From 8/1/2014 to 7/31/2015 a diagnostic algorithm that prioritized ultrasound over CT was used in our ED, and a standardized template was implemented for the reporting of appendicitis-related ultrasound findings by our radiologists.Of 627 patients diagnosed with appendicitis in the ED during the retrospective review, 46.1% (n=289) had an ultrasound. After implementation of the diagnostic algorithm and standardized ultrasound report, 88.4% (n=236) of 267 patients diagnosed with appendicitis had an ultrasound (p0.01). The frequency of indeterminate results decreased from 44.3% to 13.1%, and positive results increased from 46.4% to 66.1% in patients with appendicitis (p0.01). The sensitivity of ultrasound (indeterminate counted as negative) increased from 50.6% to 69.2% (p0.01).Ultrasound reliability for the diagnosis of appendicitis in children can be improved through standardized results reporting. However, these changes should be made as part of a multidisciplinary quality improvement initiative to account for the initial learning curve necessary to increase experience.Level II, Study of Diagnostic Test.

Ultrasound assessments of children with possible acute appendicitis (AA) are often nondiagnostic. We aimed to identify the predictors of nondiagnostic ultrasound and to investigate the outcomes. A retrospective review was conducted on children aged 4 to 17 years evaluated in 2013 for AAwith ultrasound at a tertiary hospital pediatric emergency department. Demographics, clinical data, and outcomes were analyzed. Of 528 children, 194 (36.7%) had diagnostic ultrasounds and 334 (63.3%) had nondiagnostic ultrasounds. Nondiagnostic ultrasounds were more common after-hours (7 pm–7 am weekdays and on weekends, 70.7%) than during business hours (7 am–7 pm weekdays; 29.3%). After-hours timing and female sex were identified as independent predictors of non-diagnostic ultrasounds (P < 0.05 for both). AA was diagnosed in 35 children with a nondiagnostic ultrasound (10.5%; P < 0.05). No child who underwent a nondiagnostic ultrasound was found to have AA with laboratory values of white blood cell < 11 x 103/μL and c-reactive protein (CRP) < 5 mg/dL. Children with nondiagnostic ultrasounds have a low likelihood of AA if white blood cell < 11 and CRP < 5. We propose a management algorithm that we hope will help reduce admissions and decrease the use of computed tomography scans.

Background High narcotic requirements after minimally invasive repair of pectus excavatum (MIRPE) can increase the risk of urinary retention. Placement of intraoperative Foley catheters to minimize this risk is variable. This study determines the rate of urinary retention in this population to guide future practice. Materials and Methods We reviewed retrospectively all patients who underwent MIRPE from January 2012 to July 2016 at 2 academic children's hospitals. Data collected included demographics, BMI, severity of the pectus defect, postoperative pain management, and the incidence of urinary retention and urinary tract infection (UTI). Results Of 360 total patients who underwent MIRPE, 218 had an intraoperative Foley catheter. Patients with epidural pain control were more likely to receive a Foley catheter. The urinary retention rate was 34% for patients without an intraoperative Foley, and 1% in patients after removal of an intraoperatively placed Foley. Urinary retention was greater with an epidural compared with patient-controlled anesthesia (55% vs 26%, P = .002) in the no intraoperative Foley group. No urinary tract infections were identified. Epidural pain control was the only risk factor on multivariate analysis for retention in patients without an intraoperatively Foley catheter. Conclusion Intraoperative Foley catheters obviate urinary retention without increasing the risk of urinary tract infection after MIRPE. These results will allow surgeons to better counsel patients regarding Foley placement.

It has been postulated that children with Hirschsprung disease (HD) and mucosal eosinophilia have been thought to have poorer outcome, but supporting evidence is lacking. The objective of our study was to review the outcomes of children with HD and mucosal eosinophilia. A single center, retrospective review was conducted on all patients diagnosed with HD between 1999 and 2016. Pathology specimens were evaluated for mucosal eosinophilia. Demographics, complications, and outcomes were analyzed. A total of 100 patients were diagnosed with HD and 27 had mucosal eosinophilia. Median age at the time of surgery was 12 days (8, 30) and 82 were males. Comparing patients with HD with and without mucosal eosinophilia, there was no statistically significant difference in time to bowel function (2 days vs. 2 days; p = 0.85), time to start feeds (3 days vs. 3 days; p = 0.78) and time to goal feeds (5 days vs. 5 days; p = 0.47). There was no statistically significant difference in feeding issues (13% vs. 9%; p = 1.0) and stooling issues (60% vs. 50%; p = 0.38). There was no statistically significant difference in postoperative complications and readmissions rates (63% vs. 56%; p = 0.53). Hirschsprung-associated mucosal eosinophilia may not increase postoperative complications, and may not change feeding and bowel management. Further prospective studies are in process to evaluate long term follow-up outcomes for this patient population.

Traditional methods for securing a laparoscopic gastrostomy (LG) involve the placement of two monofilament transabdominal (TA) sutures to be removed after a short interval of 5 days. A modified technique employing an absorbable suture tunneled subcutaneously has been adopted by many surgeons. The aim of this study was to compare wound complications between these techniques.A retrospective review of patients who underwent LG placement between 2010 and 2016 was conducted, dividing patients into two cohorts by securing stitch type, TA and subcutaneous (SC), and evaluating for complications.A total of 740 children underwent laparoscopic gastrostomy tube (GT) placement, of whom 554 (75%) patients had a TA stitch and the remaining 186 (25%) had a SC stitch. Demographic data were comparable in both groups. The most common wound complication was granulation tissue (22%), dislodgement (19%), external drainage (16%), cellulitis (10%), erosion (3%), and abscess formation (2%). Seven patients required operative revision for dislodgement; TA patients comprised the majority of these patients. Operative times were significantly longer in the SC group (22 minutes versus 28 minutes, P .05). Rates of granulation, erosion, external and internal leakage, and dislodgement were equivalent between cohorts. There were higher rates of cellulitis (7.3% versus 19%, P .05) and abscess (0.8% versus 7.6%, P .05) noted in the SC group. Time to external leakage was significantly earlier in the SC group (P .05); however, all other complications occurred at comparable times following initial operation. Persistent gastrocutaneous fistula requiring surgical closure occurred at equal rates with no difference in times to closure from GT discontinuation in both groups.While both techniques are feasible, there was a significant increase in infectious complications and operative times observed in the SC stitch patients, suggesting this may not be the optimal securing method.

Introduction The recent increased awareness of the dangers of opioids in the United States has highlighted the need to minimize narcotics and identify nonopioid options for pain control after surgery. With evidence suggesting that intravenous acetaminophen (IVA) can be an opioid sparing option, we conducted a prospective, randomized trial that evaluated the effect of IVA on the postoperative pain course of children with perforated appendicitis. Materials and Methods After IRB approval, children with perforated appendicitis were randomized to receive postoperative IVA with the standard patient/nurse-controlled analgesia (PCA) or to receive the PCA alone. All patients were treated according to an evidence-based treatment protocol. The primary outcome was duration of time on PCA. Results Eighty-two patients were analyzed from 7/14 to 11/15. There was no statistically significant difference in the time to transition from the PCA to oral pain medications for children given IVA compared with children not receiving IVA (76.4 ± 32.5 versus 86.7 ± 49.3 hours; p = 0.73). Children in the IVA group had no statistically significant difference in intravenous narcotics delivered and pain scores compared with the non-IVA group. There was no significant difference in the amount of oral narcotics between both groups (2.8 ± 2.4 versus 2.9 ± 2.5; p = 0.88). Patients who received IVA had higher medication charges ($3752.7 ± 1618.3 vs. $1198.19 ± 521.51; p Conclusion Children given IVA showed no difference in the transition time off the PCA and to oral pain medications after laparoscopic appendectomy for perforated appendicitis.

Background The ability of ultrasound to identify specific features relevant to nonoperative management of pediatric appendicitis, such as the presence of complicated appendicitis (CA) or an appendicolith, is unknown. Our objective was to determine the reliability of ultrasound in identifying these features. Methods We performed a retrospective study of children who underwent appendectomy after an ultrasound at four children's hospitals. Imaging, operative, and pathology reports were reviewed. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of ultrasound for identifying CA based on pathology and intraoperative findings and an appendicolith based on pathology were calculated. CA was defined as a perforation of the appendix. Equivocal ultrasounds were considered as not indicating CA. Results Of 1027 patients, 77.5% had simple appendicitis, 16.2% had CA, 5.4% had no evidence of appendicitis, and 15.6% had an appendicolith. Sensitivity and specificity of ultrasound for detecting CA based on pathology were 42.2% and 90.4%; the PPV and NPV were 45.8% and 89.0%, respectively. Sensitivity and specificity of ultrasound for detecting CA based on intraoperative findings were 37.3% and 92.7%; the PPV and NPV were 63.4% and 81.4%, respectively. Sensitivity and specificity of ultrasound for detecting an appendicolith based on pathology were 58.1% and 78.3%; the PPV and NPV were 33.1% and 91.0%, respectively. Results were similar when equivocal ultrasound and negative appendectomies were excluded. Conclusions The high specificity and NPV suggest that ultrasound is a reliable test to exclude CA and an appendicolith in patients being considered for nonoperative management of simple appendicitis.

An estimated 3.6 million reports of possible child abuse or neglect, also known as nonaccidental trauma (NAT) or nonaccidental injury, involving approximately 6.6 million children were made to child protective services in the United States in 2014. The annual societal cost of child abuse and neglect is estimated conservatively to be over $103 billion. Understanding the history and physical findings specific to NAT will allow physicians to identify those children at risk and avoid missed injuries and recurrent child abuse. Bruising in particular is a cardinal physical finding for NAT. Certain diagnostic tools, such as skeletal surveys and retinal examinations, are used in evaluating for NAT. Abusive head trauma is the most common and deadliest injury. Although less common, abdominal injuries have a high mortality due to nonspecific symptoms and delayed presentation. Solid-organ abdominal injuries and duodenal hematomas can be managed nonoperatively, with a low failure rate. Up to 25% of skeletal fractures for children less than 1 year old are due to NAT. Tools to help medical personnel identify NAT are vitally important because children with recurrent NAT have a higher mortality compared with those identified at the initial episode. In Europe and the United States, checklists and algorithms have been established to standardize management of children with NAT. NAT carries significant morbidity, mortality, and cost to families and hospital resources. The key to prevention is early identification of children with NAT and early involvement of general or pediatric surgeons.

Introduction Non-accidental trauma (NAT) has significant societal and health care implications. Standardized care has been shown to improve outcomes. The purpose of our study was to survey trauma centers and elucidate the continued variable management of NAT. Methods After institutional review board approval, an email survey was sent to Level 1 and 2 ACS verified trauma centers along with general and pediatric surgery training programs. Trauma hospital characteristics and NAT management were analyzed. Results A total of 493 emails were sent and 91 responses (18%) were received. There were 74 (81%) pediatric surgeons who responded and 15(17%) adult general surgeons. The most common location of respondents were children’s hospitals within academic/community hospitals (58%) followed by stand-alone children hospitals (42%), and adult only hospitals (9%). 51 (57%) providers reported using a screening tool; most commonly used by the emergency department (52%). 75% of providers reported utilizing management protocols in which 71% were initiated by trauma surgery. The most common consulting and admitting service for NAT was trauma surgery (86% and 84%). When comparing stand-alone and affiliated children hospitals, there was no difference in the use of a screening tool (54% vs. 59%; p = 0.84), and management protocol (70% vs. 85%; p = 0.19). However, those providers from pediatric trauma centers used a management protocol more often than providers from adult trauma centers (78% vs. 38%; p = 0.04). No providers from adult trauma centers had intentions to initiate a management protocol in the future. Conclusion Screening and management of non-accidental trauma continues to vary across the country. Future studies focusing on standardization and outreach/education to adult trauma centers is warranted.

Congenital diaphragmatic hernia (CDH) can be repaired open or through thoracoscopy. Thoracoscopic CDH repair could improve cosmesis and avoid the complications of laparotomy, but may have higher recurrence rates. The purpose of this study was to examine the outcomes of thoracoscopic versus open CDH repair, with regard to recurrence, perioperative parameters, and postoperative complications.We performed a retrospective review of open versus thoracoscopic CDH repairs over an 8.5-year period. The primary outcome was hernia recurrence. Secondary outcomes included intraoperative partial pressure of carbon dioxide (pCOA total of 54 infants underwent CDH repair during the study period, of whom 25 underwent successful thoracoscopic repair. Two patients who had undergone open repair developed recurrent diaphragmatic hernias (recurrence rate 3.7%). Operative time and intraoperative pCOIn our experience, thoracoscopic CDH repair was performed safely and with similar outcomes compared to open repair. In addition to improved cosmesis, thoracoscopic repair may avoid some of the long-term complications of laparotomy. In our series, none of the thoracoscopic CDH repairs recurred. We conclude that thoracoscopic CDH repair is a safe and appropriate technique for select neonates.

Patient-controlled analgesia (PCA) is often used in children with perforated appendicitis. To prevent urinary retention, some providers also routinely place Foley catheters. This study examines the necessity of this practice.We retrospectively reviewed all children (≤18 years old) with perforated appendicitis and postoperative PCA from 7/2015 to 6/2016 at two academic children's hospitals. Urinary retention was defined as the inability to spontaneously void requiring straight catheterization or placement of a Foley catheter.Of 313 patients who underwent appendectomy for perforated appendicitis (Hospital 1: 175, Hospital 2: 138), 129 patients received an intraoperative Foley (Hospital 1: 22 [13%], Hospital 2: 107 [78%], p 0.001). Age, gender, and BMI were similar between those with an intraoperative Foley and those without. There were no urinary tract infections in either group. Urinary retention rate in patients with an intraoperative Foley following removal on the inpatient unit (n = 3, 2%) and patients without an intraoperative Foley (n = 10, 5%) did not reach significance (p = 0.25). On univariate analysis, demographics, intraoperative findings, PCA specifics, postoperative abscess formation, and postoperative length of stay, were not significant risk factors for urinary retention.The risk of urinary retention in this population is low despite the use of PCA. Children with perforated appendicitis do not require routine Foley catheter placement to prevent urinary retention.II.

To review the outcomes of magnet ingestions from two children's hospitals and develop a clinical management pathway.Children18years old who ingested a magnet were reviewed from 1/2011 to 6/2016 from two tertiary center children's hospitals. Demographics, symptoms, management and outcomes were analyzed.From 2011 to 2016, there were 89 magnet ingestions (50 from hospital 1 and 39 from hospital 2); 50 (56%) were males. Median age was 7.9 (4.0-12.0) years; 60 (67%) presented with multiple magnets or a magnet and a second metallic co-ingestion. Suspected locations found on imaging were: stomach (53%), small bowel (38%), colon (23%) and esophagus (3%). Only 35 patients (39%) presented with symptoms and the most common symptom was abdominal pain (33%). 42 (47%) patients underwent an intervention, in which 20 (23%) had an abdominal operation. For those undergoing abdominal surgery, an exact logistic regression model identified multiple magnets or a magnet and a second metallic object co-ingestion (OR 12.9; 95% CI, 2.4 - Infinity) and abdominal pain (OR 13.0; 95% CI, 3.2-67.8) as independent risk factors.Magnets have a high risk of requiring surgical intervention for removal. Therefore, we developed a management algorithm for magnet ingestion.Level III.

To review current management and outcomes of ingested batteries and develop a clinical management algorithm.Children18years old who ingested a battery between 1/2011 and 9/2016 at two tertiary care children's hospitals were reviewed. Demographics, imaging, management and outcomes were analyzed using descriptive statistics, Chi-square and Wilcoxon Rank-sum tests.There were 180 battery ingestions. The median age was 3.9 (range 0.7-18) years, with 78 (43%) males. The most common symptoms were abdominal pain (17%) and nausea/vomiting (14%). Diagnosis was confirmed with plain radiographs in 170 (94%) patients. Locations on imaging were: stomach (37%), small bowel (24%), esophagus (18%), colon (11%), and non-specific location past the gastroesophageal junction (9%). Treatment was dictated by five different subspecialties including surgery (35%), gastroenterology (25%), emergency medicine (19%), primary care/emergency with a consulting service (13%), and otolaryngology (8%). All esophageal batteries (n=33) had an intervention. Interventions included fluoroscopic balloon extraction (6 attempted, 33% retrieval rate), rigid esophagoscopy (26 attempted, 96% retrieval rate), and EGD (6 attempted, 83% retrieval rate). For batteries distal to the gastroesophageal junction 16 (11%) patients had an intervention. Interventions included EGD (13 patients, 69% retrieval), colonoscopy (1 patient, successful retrieval), and abdominal surgery in two patients.Isolated batteries that pass the gastroesophageal junction rarely require intervention and can be managed conservatively. Given the variability in managing these patients, we developed an evidence based algorithm.Level 2.Retrospective Study.

Complications from shunts placed in the peritoneum, either ventriculoperitoneal or subdural, are varied. Perforation of hollow organs and subsequent natural orifice protrusion is a rare but well known complication. We report a case of a transanal protrusion of a subdural peritoneal shunt in the setting of previous abdominal pain possibly consistent with acute appendicitis. While a report of transanal protrusion of a ventriculoperitoneal shunt via the appendix has been reported this is the first report where abdominal inflammation was also present. While patients with hollow organ perforation have been described as being managed conservatively after externalization of the proximal shunt and removal of the distal shunt, we managed our patient with an operation given our concern for appendicitis.

The aim of this study was to evaluate the national trends in surgical management of ovarian torsion (OT) in children. The Nationwide Inpatient Sample was queried from 1998 to 2011 for females less than 18 years of age with OT. Patients were stratified into three treatment groups: oophorectomy (OO), oophoropexy, or release of torsion (RT) alone. There were 2041 patients with OT, of which 1598 (78%) underwent OO, 126 (6%) oophoropexy, and 317 (15%) RT. RT significantly increased from 1998 to 2011 (9% vs 25%; P0.05). At nonteaching hospitals, there were higher rates of OO (89.3% vs 79.5%; P0.05) and lower rates of RT (10.7% vs 20.5%; P0.05) compared with teaching hospitals. RT was performed at a higher rate in Northeast United States compared with the South (22.7% vs 14.2%; P0.05). Girls presenting at nonteaching hospitals and the South had increased odds of undergoing OO compared with those presenting at teaching hospitals and the Northeast (P0.05). Although ovarian conservation for OT in children is more often performed in the Northeast United States and at teaching hospitals, this large population-based study demonstrates OO remains the most common surgical management for OT in the United States.

Pancreatic and peripancreatic fluid collections may develop after severe acute pancreatitis. Organized fluid collections such as pancreatic pseudocyst and walled-off pancreatic necrosis (WOPN) that mature over time may require intervention to treat obstructive or constitutional symptoms related to the size and location of the collection as well as possible infection. Endoscopic, open surgical and minimally invasive techniques are described to treat post-inflammatory pancreatic fluid collections. Surgical intervention may be required to treat collections containing necrotic pancreatic parenchyma or in locations not immediately apposed to the stomach or duodenum. Comprising a blend of the surgical approach and the clinical benefits of minimally invasive surgery, the robot-assisted technique of pancreatic cystgastrostomy with pancreatic debridement is described.

The Cambodian Kaléidoscope, by Richard Sola After Norodom Sihanouk was imposed as King of Cambodia by France, he quickly proved himself a clever negotiator as well as an often cruel autocrat. But he was also a demagogue who adopted socialist rhetoric and was caught in the wave of communism which spread from Indochina and eventually brought his downfall. He was deposed in 1970 and since then has unceasingly sought vengeance against Lon Nol and the United States, who did not understand the difficulties of his non-alignment. To this end, he did not hesitate to play China's game by allying himself with the « Khmers Rouges » whom he had earlier driven out. He was their prisoner from 1975-1978 and was saved by the Chinese when his former allies, the Vietnamese invaded. Under the présent circumstances in Cambodia, could Sihanouk still be useful as a symbol or has he betrayed too often ?, Imposé comme roi du Cambodge par la France, Norodom Sihanouk se montre vite un négociateur rusé mais aussi un autocrate souvent cruel. Démagogue mais objet aussi de la décolonisation et de la poussée communiste en Indochine, il s'enferme dans un discours socialiste dont il sera la victime. Déposé en 1970, il n'aura de cesse de vouloir se venger de Lon Nol et des Etats-Unis qui n'auront pas su comprendre les difficultés de son non-alignement. Pour se faire, il n'hésitera pas à faire le jeu de la Chine populaire en s'alliant avec les Khmers rouges qu'il avait pourtant pourchassés auparavant. Prisonnier de ces derniers de 1975 à 1978, il sera sauvé par les Chinois face à l'invasion des Vietnamiens, ses anciens alliés. Compte tenu de la situation au Cambodge, le prince Sihanouk est-il encore un symbole ou bien a t-il trop trahi pour être encore utilisé ?, Sola Richard. Le kaléidoscope cambodgien.
