Bilateral cardiac sympathetic denervation in patients with congenital long QT syndrome.

BACKGROUND: Long QT syndrome (LQTS) is a potentially lethal yet treatable genetic heart disease for which left cardiac sympathetic denervation (LCSD) is a class I recommendation. Recent reports have suggested bilateral cardiac sympathetic denervation (BiCSD) as the initial surgical denervation therapy in LQTS. OBJECTIVE: The purpose of this study was to determine the frequency and settings in which BiCSD was used in a tertiary referral center with expertise in LCSD. METHODS: We performed a retrospective review of 234 out of 1638 patients with LQTS who underwent sympathetic denervation (14%) at our institution to identify the subset of patients who underwent BiCSD. Cardiac events (CEs) before LCSD, after LCSD, and after the completion of BiCSD were recorded and defined as being an appropriate implantable cardioverter-defibrillator shock, arrhythmic syncope, or sudden cardiac arrest. RESULTS: Only 11 patients (4.7%; 6 females [55%]) had BiCSD at our institution. Patients who received BiCSD trended toward being younger at diagnosis (6 ± 15 years vs 14 ± 13 years; P = .06) and being more likely to be symptomatic (73% vs 53%; P = .07) than the larger LCSD-only cohort. Continued CEs post-LCSD (3.8 CEs per patient on average) was the predominant determinant to return for BiCSD. Over 60 combined years of follow-up, 4 patients have not had a CE post-BiCSD while the other 7 patients average 3.6 nonlethal CEs. CONCLUSION: Less than 5% of all patients receiving denervation therapy underwent BiCSD. When BiCSD was chosen, it was almost always done in a staged sequential manner beginning with LCSD first and when driven by the arrhythmogenicity of the LQTS substrate, despite otherwise optimized guideline-directed therapies.

Incidence and risk of attention-deficit/hyperactivity disorder and learning disability by adulthood after traumatic brain injury in childhood: a population-based birth cohort study.

The aim of this study was to understand the risk of developing attention-deficit/hyperactivity disorder (ADHD) or learning disability (LD) after childhood traumatic brain injury (TBI) in a population-based birth cohort. Cases of TBI for children from birth to 10 years were confirmed and stratified by severity of injury. For each TBI case, two age-matched and sex-matched referents without TBI were identified from the same birth cohort. Presence of ADHD and LD before age 19 were confirmed using medical and/or school records. Associations between TBI exposure and subsequent ADHD or LD were assessed in multivariable Cox regression models, adjusting for maternal age, education, and race. The incidence rate of TBI before age 10 was 1,156 per 100,000 person-years. Children who had a TBI before age 10 were more likely to have met the research criteria for ADHD (hazard ratio [HR], 1.68; 95% CI, 1.15-2.45) or LD (HR, 1.29; 95% CI, 1.00-1.68) by age 19. No statistically significant associations were shown between TBI and ADHD or LD when restricted to definite and probable TBI cases (consistent with moderate to severe and mild TBI, respectively) and their referents. Significant associations were shown when the analysis was confined to possible TBI cases (consistent with concussive TBI) and their referents (ADHD: HR, 2.05; 95% CI, 1.31-3.20; and LD: HR, 1.42; 95% CI, 1.05-1.91). Increased risk for developing ADHD and LD by adulthood was shown particularly for children with the least-severe injuries, indicating that factors other than trauma-related altered brain function likely contribute to this risk.

Post-injury outcomes of children with behavioral health disorders.

BACKGROUND: The impact of Behavioral Health Disorders (BHDs) on pediatric injury is poorly understood. We investigated the relationship between BHDs and outcomes following pediatric trauma. METHODS: We analyzed injured children (age 5-15) from 2014 to 2016 using the Pediatric Trauma Quality Improvement Program. The primary outcome was in-hospital mortality. Univariable and multivariable analyses compared children with and without a comorbid BHD. RESULTS: Of 69,305 injured children, 3,448 (5%) had a BHD. These 3,448 children had a median of 1 [IQR: 1, 1] BHD diagnosis: ADHD (n = 2491), major psychiatric disorder (n = 1037), drug use disorder (n = 250), and alcohol use disorder (n = 29). A higher proportion of injured children with BHDs suffered intentional and penetrating injury. Firearm injuries were more common for BHD patients (3% vs 1%, p<0.001). Children with BHDs were more likely to have an ISS>25 compared to children without (5% vs 3%, p<0.001). While median LOS was longer for BHD patients (2 [1, 3] vs 2 [1, 4], p<0.001), mortality was similar (1% vs 1%, p = 0.76) and complications were less frequent (7% vs 8%, p = 0.002). BHD was associated with lower risk of mortality (OR 0.45, 95%CI [0.30, 0.69]) after controlling for age, sex, race, trauma type, and injury intent and severity. CONCLUSION: Children with BHDs experienced lower in-hospital mortality risk after traumatic injury despite more severe injury upon presentation. Intentional and penetrating injuries are particularly concerning, and future work should assess prevention efforts in this vulnerable group.

Evolution of pediatric gastrointestinal ulcer disease: Is acute surgical intervention relevant?

BACKGROUND: There is a lack of contemporary data about pediatric gastrointestinal ulcer disease. We hypothesized that ulcers found in immunosuppressed children were more likely to require surgical intervention. METHODS: All children <21 years (n = 129) diagnosed with ulcers at a quaternary hospital from 1990 to 2019 were retrospectively reviewed. Clinical findings and pertinent information were collected. RESULTS: Of 129 cases, 19 (14.7%) were immunosuppressed. Eight were post-transplant; four were diagnosed with post-transplant lymphoproliferative disease (PTLD).  Eight were associated with cancer. Three were both.  Three of 19 immunosuppressed and 28/110 immunocompetent patients were taking acid suppression therapy. Nine immunosuppressed patients required surgical intervention, including all PTLD cases, compared to 14 immunocompetent (47.3% vs 16.4%, p < 0.01). Five patients had duodenal perforation, two had multiple small bowel perforations, and two had uncontrolled bleeding. Of 9/19 immunosuppressed patients, surgical complications included bleeding (n = 7), sepsis (n = 2), ostomy reoperation/readmissions (n = 2), and death within 30 days (n = 2). Two/eighteen immunocompetent patients had bleeding complications. CONCLUSION: Surgical treatment for ulcers remains relevant for pediatric patients. Immunosuppressed patients have more complications, longer hospital stays, and are more likely to need surgical intervention. Efforts should be made for ulcer prophylaxis with a low threshold to investigate epigastric pain in these complex patients. LEVEL OF EVIDENCE: Prognosis Study Level III Evidence.

CT scans for pediatric injury in a middle-income country trauma center: Are we repeating past mistakes?

PURPOSE: Sustained efforts in high-income countries have decreased the rate of unnecessary computed tomography (CT) among children, aiming to minimize radiation exposure. There are little data regarding CT use for pediatric trauma in low- and middle-income countries. We aimed to assess the pattern and utility of CT performed during evaluation of trauma patients presenting to a middle-income country (MIC) trauma center. METHODS: We reviewed pediatric (age<18) trauma admissions at a single tertiary referral center in South Africa. Patient demographics, injury details, surgical intervention(s), and mortality were abstracted from the medical record. CT indications, results, and necessity were determined by review. RESULTS: Of 1,630 children admitted to the trauma center, 826 (51%) had CT imaging. Children undergoing imaging were younger (median age 11 [IQR: 6, 16] vs 13 [IQR: 7, 17]) and had higher median ISS [9 [IQR: 4, 13] vs 4 [2, 9]) compared to those without imaging (both p<0.001). Overall, 1,224 scans were performed with normal findings in 609 (50%). A median of 1 scan was performed per patient (range: 1-5). The most common location was CT head (n = 695, 57%). Among patients with positive findings on CT head (n = 443), 31 (7%) underwent either intracranial pressure monitoring or surgery. CT of the cervical spine had positive findings in 12 (7%) with no patients undergoing spine surgery. Of 173 patients with abdominal CT imaging, 83 (48%) had abnormal findings and 18 (10%) required operative exploration. Thirteen (16%) patients with abnormal findings on abdominal CT had exploratory laparotomy. Of 111 children undergoing whole body CT, 8 (7%) underwent thoracic and/or abdominal operations. CONCLUSION: Use of CT during evaluation of pediatric trauma is common in an MIC center. A high rate of normal findings and low rates of intervention following head, cervical spine, and abdominal CT suggest potential overuse of this resource. LEVEL OF EVIDENCE: Level III.

Surgical Simulation in East, Central, and Southern Africa: A Multinational Survey.

BACKGROUND: High-income countries have increased the use of simulation-based training and assessment for surgical education. Learners in low- and middle-income countries may have different educational needs and levels of autonomy but they and their patients could equally benefit from the procedural training simulation provides. We sought to characterize the current state of surgical skills simulation in East, Central, and Southern Africa and determine residents' perception and future interest in such activities. METHODS: A survey was created via collaboration and revision between trainees and educators with experiences spanning high-income countries and low- and middle-income countries. The survey was administered on paper to 76 trainees (PGY2-3) who were completing the College of Surgeons of East, Central, and Southern Africa (COSECSA) Membership of the College of Surgeons examination in Kampala, Uganda in December 2019. Data from paper responses were summarized using descriptive statistics and frequencies. RESULTS: We received responses from 43 trainees (57%) from 11 countries in sub-Saharan Africa who participated in the examination. Fifty-eight percent of respondents reported having dedicated space for surgical skills simulation training, and most (91%) had participated in some form of simulation activity at some point in their training. However, just 16% used simulation as a regular part of training. The majority of trainees (90%) felt that surgical skills learned in simulation were transferrable to the operating room and agreed it should be a required part of training. Seventy-one percent of trainees felt that simulation could objectively measure technical skills, and 73% percent of respondents agreed that simulation should be integrated into formal assessment. However, residents split on whether proficiency in simulation should be achieved prior to operative experience (54%) and if nontechnical skills could be measured (51%). The most common cited barriers to the integration of surgical simulation into residents' education were lack of suitable tools and models (85%), funding (73%), and maintenance of facilities (49%). CONCLUSIONS: Residents from East, Central, and Southern Africa strongly agree that simulation is a valuable educational tool and ought to be required during their surgical residency. Barriers to achieving this goal include availability of affordable tools, adequate funding and confidence in the value of the educational experience. Trainees affirm further efforts are necessary to make simulation more widely available in these contexts.

A Comparison of Single-Incision Versus Multiport Laparoscopic Splenectomy in Children.

Background: Although single-incision endoscopic splenectomy (SIES-Sp) has been shown to be feasible and safe, few have compared the SIES-Sp with multiport laparoscopic splenectomy (MPLS). The purpose of this study was to compare the two techniques in children undergoing total splenectomy. Materials and Methods: We reviewed all children (age <18 years) who underwent minimally invasive total splenectomy at a single tertiary referral center from January 1, 2000 to January 1, 2019. The primary outcome was complication rate 30 days after discharge defined by maximum Clavien-Dindo score. Secondary outcomes included conversion, operative time, hospital length of stay, postoperative pain scores, and readmission within 30 days of discharge. SIES-Sp and MPLS were compared using univariate analysis. Results: Of 48 children undergoing laparoscopic total splenectomy, 60% (n = 29) were SIES-Sp and 40% (n = 19) were MPLS. Subjects were 48% female (n = 23). Common diagnoses were idiopathic thrombocytopenic purpura (33% [n = 16]), hereditary spherocytosis (29% [n = 14]), and other congenital hemolytic anemias (23% [n = 11]). There were no differences in age, gender, or diagnosis between groups (all P > .05). One in three cases involved additional procedures. Spleens were smaller in both greatest dimension (13.0 cm versus 16.4 cm) and weight (156.5 g versus 240.0 g) in SIES-Sp compared with MPLS patients (both P < .05). Readmission and reoperation rates were similar (both P > .05). Complications occurred in 7% (n = 2) of SIES-Sp and in 11% (n = 2) of MPLS patients (P > .99). Severe complications included: cardiac arrest in 1 SIES-Sp patient and bleeding requiring reoperation in 1 MPLS patient. Conclusion: SIES-Sp is a safe alternative to the traditional MPLS for children. Additional procedures do not preclude a less invasive approach, but larger spleens may present a challenge.

Left Cardiac Sympathetic Denervation Monotherapy in Patients With Congenital Long QT Syndrome.

BACKGROUND: Videoscopic left cardiac sympathetic denervation (LCSD) is an effective antifibrillatory, minimally invasive therapy for patients with potentially life-threatening arrhythmia syndromes like long QT syndrome (LQTS). Although initially used primarily for treatment intensification following documented LQTS-associated breakthrough cardiac events while on beta-blockers, LCSD as 1-time monotherapy for certain patients with LQTS requires further evaluation. We are presenting our early experience with LCSD monotherapy for carefully selected patients with LQTS. METHODS: Among the 1400 patients evaluated and treated for LQTS, a retrospective review was performed on the 204 patients with LQTS who underwent LCSD at our institution since 2005 to identify the patients where the LCSD served as stand-alone, monotherapy. Clinical data on symptomatic status before diagnosis, clinical, and genetic diagnosis, and breakthrough cardiac events after diagnosis were analyzed to determine efficacy of LCSD monotherapy. RESULT: Overall, 64 of 204 patients (31%) were treated with LCSD alone (37 [58%] female, mean QTc 466±30 ms, 16 [25%] patients were symptomatic before diagnosis with a mean age at diagnosis 17.3±11.8 years, 5 had [8%] ≥1 breakthrough cardiac event after diagnosis, and mean age at LCSD was 21.1±11.4 years). The primary motivation for LCSD monotherapy was an unacceptable quality of life stemming from beta-blocker related side effects (ie, beta-blocker intolerance) in 56/64 patients (88%). The underlying LQTS genotype was LQT1 in 36 (56%) and LQT2 in 20 (31%). There were no significant LCSD-related surgical complications. With a mean follow-up of 2.7±2.4 years so far, only 3 patients have experienced a nonlethal, post-LCSD breakthrough cardiac event in 180 patient-years. CONCLUSIONS: LCSD may be a safe and effective stand-alone therapy for select patients who do not tolerate beta-blockers. However, LCSD is not curative and patient selection will be critical when potentially considering LCSD as monotherapy.

Comparison of the Pediatric Resuscitation and Trauma Outcome (PRESTO) Model and Pediatric Trauma Scoring Systems in a Middle-Income Country.

BACKGROUND: The pediatric resuscitation and trauma outcome (PRESTO) model was developed to aid comparisons of risk-adjusted mortality after injury in low- and middle-income countries (LMICs). We sought to validate PRESTO using data from a middle-income country (MIC) trauma registry and compare its performance to the Pediatric Trauma Score (PTS), Revised Trauma Score, and pediatric age-adjusted shock index (SIPA). METHODS: We included children (age < 15 years) admitted to a single trauma center in South Africa from December 2012 to January 2019. We excluded patients missing variables necessary for the PRESTO model-age, systolic blood pressure, pulse, oxygen saturation, neurologic status, and airway support. Trauma scores were assigned retrospectively. PRESTO's previously high-income country (HIC)-validated optimal threshold was compared to MIC-validated threshold using area under the receiver operating characteristic curves (AUROC). Prediction of in-hospital death using trauma scoring systems was compared using ROC analysis. RESULTS: Of 1160 injured children, 988 (85%) had complete data for calculation of PRESTO. Median age was 7 (IQR: 4, 11), and 67% were male. Mortality was 2% (n = 23). Mean predicted mortality was 0.5% (range 0-25.7%, AUROC 0.93). Using the HIC-validated threshold, PRESTO had a sensitivity of 26.1% and a specificity of 99.7%. The MIC threshold showed a sensitivity of 82.6% and specificity of 89.4%. The MIC threshold yielded superior discrimination (AUROC 0.86 [CI 0.78, 0.94]) compared to the previously established HIC threshold (0.63 [CI 0.54, 0.72], p < 0.0001). PRESTO showed superior prediction of in-hospital death compared to PTS and SIPA (all p < 0.01). CONCLUSION: PRESTO can be applied in MIC settings and discriminates between children at risk for in-hospital death following trauma. Further research should clarify optimal decision thresholds for quality improvement and benchmarking in LMIC settings.

Left cardiac sympathetic denervation reduces skin sympathetic nerve activity in patients with long QT syndrome.

BACKGROUND: Although left cardiac sympathetic denervation (LCSD) is an effective antiarrhythmic therapy for patients with long QT syndrome (LQTS), direct evidence of reduced sympathetic activity after LCSD in humans is limited. OBJECTIVE: The purpose of this study was to assess skin sympathetic nerve activity (SKNA) in patients with LQTS undergoing LCSD. METHODS: We prospectively enrolled 17 patients with LQTS who underwent LCSD between 2017 and 2019. SKNA recordings from the left arm (L-SKNA) and chest (C-SKNA) leads were performed before and after LCSD. Mean SKNA, burst activity, and nonburst activity of L-SKNA and C-SKNA were analyzed. RESULTS: The mean patient age was 21 ± 9 years (8 men 47%). The longest baseline corrected QT value was 497 ± 55 ms at rest and 531 ± 38 ms on exercise stress testing. Five patients (29.4%) had previous LQTS-triggered cardiac events including syncope, documented torsades de pointes, and ventricular fibrillation. In the 24 hours after LCSD, mean L-SKNA decreased from 1.25 ± 0.64 to 0.85 ± 0.33 µV (P = .005) and mean C-SKNA from 1.36 ± 0.67 to 1.05 ± 0.49 µV (P = .11). The frequency of episodes of SKNA bursts recorded from the left-arm lead (2.87 ± 1.61 bursts per minute vs 1.13 ± 0.99 bursts per minute; P < .001) and mean L-SKNA during burst (1.82 ± 0.79 µV vs 1.15 ± 0.44 µV; P < .001) and nonburst (1.09 ± 0.60 µV vs 0.75 ± 0.32 µV; P = .03) periods significantly decreased after LCSD, while the frequency of episodes of SKNA bursts recorded from the chest lead (P = .57) and mean C-SKNA during burst (P = .44) and nonburst (P = .10) periods did not change significantly. No arrhythmic events were documented after 11.9 months (range 3.0-22.2 months) of follow-up. CONCLUSION: LCSD provides an inhibitory effect on cardiac sympathetic activity by suppressing burst discharge as measured by SKNA.

Follow-up outcomes of pediatric patients who underwent surgical resection for lipoblastomas or lipoblastomatosis: a single-institution experience with a systematic review and meta-analysis.

PURPOSE: The objective of this study was to examine the long-term outcomes of pediatric patients who underwent surgical resection for lipoblastoma and lipoblastomatosis (LB/LBM). METHODS: A single-center retrospective study of pediatric patients with LB/LBMs seen between 1991 and 2015 was conducted. A systematic review, including studies published prior to late August 2018, was performed. Using a random effect meta-analysis, pooled weighted proportions and unadjusted odds ratios (OR) with 95% confidence intervals (CI) were calculated. RESULTS: The retrospective study included 16 patients, while the systematic review included 19 published studies consisting of 381 patients. Among 329 (82%) patients with follow-up information, the pooled recurrence rate was 16.8% (95% CI 10.9-23.5%; I2 = 59%). The reported time to recurrence ranged from < 1 to 8 years. Recurrence risk was greater for incomplete (n = 34) than complete resection (n = 150): OR 11.4 (95% CI 3.0-43.6; I2 = 43%). LBMs (n = 35) had a greater recurrence risk than LBs (n = 116): OR 5.5 (95% CI 1.9-15.9; I2 = 0%). Recurrences were higher for studies with approximately ≥ 3 years of follow-up versus studies with < 3 years of follow-up. CONCLUSION: Recurrences are more likely to occur with LBMs and/or incomplete resection. Follow-up beyond 3-5 years should be considered given that the recurrence risk appears to be greater in the long-term.

Fertility and Sexual Function in Women Following Pediatric Ileal Pouch-Anal Anastomosis.

PURPOSE: Ileal Pouch-Anal Anastomosis (IPAA) is the standard of care for children requiring surgical treatment of severe colitis or polyposis syndromes. This study aims is to investigate the sexual function and fertility in women after undergoing childhood IPAA. METHODS: A prospectively maintained colon and rectal database of consenting patients was queried from January 1980 to October 2015. We included all females that replied to at least 1 survey between the ages of 20 and 45 years that had undergone IPAA younger than 20 years of age. RESULTS: Two hundred females met inclusion criteria, whereas 149 women replied to the sexual function questions. Ulcerative colitis was diagnosed in 122 (83%) patients, with the remainder having polyposis. Seven patients had a laparoscopic proctectomy. Only 2 patients had a pelvic infection, whereas 21 had intestinal obstruction postoperatively. A severely restricted sex life was reported in 6 (5%) patients. Of the 93 (62%) women who attempted pregnancy, 68 (73%) became pregnant. Median age of pregnancy and IPAA was 34 (range 22-45) and 17 years (range 9-20), respectively. Medical intervention to assist fertilization was required in 14/68. A total of 29 women reported problems during pregnancy with 58/68 (88%) giving birth to a live baby. Elective termination was reported in 2/68 surveys. Vaginal delivery occurred in 26/58 mothers with 27/58 planned and 9/58 unplanned cesarean sections. Age at IPAA, diagnosis, procedure type, pelvic infection, and obstruction were not associated with decreased fertility. All 7 patients operated laparoscopically have become pregnant. Change in pouch function after delivery was reported in 20/68 (32%, 5 missing) surveys. CONCLUSIONS: 73% of women who desired children become pregnant, and 88% had a successful delivery after pediatric IPAA. Only 5% reported severely restricted sexual function. Changes in pouch function occurred with pregnancy and persisted in 1/3 after delivery. Minimally invasive techniques may improve fertility rates but equire continued follow-up. LEVEL OF EVIDENCE: Level IV. TYPE OF STUDY: Observational study.

Pouchogram Prior to Ileostomy Reversal after Ileal Pouch-Anal Anastomosis in Pediatric Patients: Is it Useful in the Setting of Routine EUA?

PURPOSE: To determine if there is a role for routine pouchogram before ileostomy reversal after IPAA in pediatric patients. METHODS: The medical records of pediatric patients who underwent pouchogram between 2007 and 2017 prior to ileostomy reversal after IPAA at two affiliated hospitals were reviewed for concordance between exam under anesthesia (EUA) and pouchogram findings, management of abnormal pouchogram findings, and short and long-term outcomes after ileostomy reversal. Clinical notes were used to find patient-reported symptoms at the time of pouchogram. RESULTS: Sixty patients (57% female) underwent pouchogram before planned ileostomy reversal. The median time from IPAA formation to pouchogram was 60.5 days (IQR: 46-77) and median follow-up was 4 years (IQR: 1-6). Fifty-seven patients (95%) were asymptomatic prior to reversal. Of the 40 asymptomatic patients with a normal EUA, pouchogram detected one stricture (3%), but reversal proceeded as planned. In the 16 patients with strictures on EUA, pouchogram only detected six (40%). One of 50 (2%) asymptomatic patients with normal pouchogram had anastomotic dehiscence found on EUA. Despite normal pouchogram and EUA, four asymptomatic patients required subsequent diversion for pouch-related complications between 13 and 60 months after ileostomy reversal. Three patients had pelvic pain prior to pouchogram; associated symptoms included perineal pain (n = 1) hematochezia (n = 1), and tenesmus (n = 1). EUA and pouchogram were concordant in two patients (n = 1 anastomotic complication, n = 1 pouch septum) and ileostomy reversal was delayed. In the remaining symptomatic patient, pouchogram detected an anastomotic leak where EUA detected only a stricture, and this prompted a delay in reversal. Long term, none of these patients required diversion or excision of their pouch. CONCLUSION: Routine pouchogram in asymptomatic pediatric patients does not change management and can be omitted, thereby sparing patients discomfort and unnecessary radiation exposure. Pouchogram may have diagnostic value in symptomatic patients. LEVEL OF EVIDENCE: III. TYPE OF STUDY: Study of Diagnostic Test.

The effect of diversion on readmission following ileal pouch-anal anastomosis in children.

BACKGROUND: Readmission rates as high as 20% have been reported after ileal pouch-anal anastomosis (IPAA) in children, with obstruction and dehydration as the most commonly listed reasons. We hypothesized that a diverting ileostomy contributes to unplanned readmission after IPAA creation. METHODS: Children (age <18) who underwent IPAA creation from January 2007 to August 2018 at two affiliated institutions were reviewed. Patient demographics, operative details, and post-operative length of stay (LOS) were abstracted. Unplanned readmission within 30 days and details on patient readmission were reviewed. RESULTS: Ninety-three patients (57% female) with a median age of 15 years (range: 18 months-17 years) underwent IPAA. Indications for IPAA included ulcerative colitis (n = 63; 68%), familial adenomatous polyposis (n = 24; 26%), indeterminate colitis (n = 5; 5%), and total colonic Hirschsprung's (n = 1; 1%). Sixty-one (66%) patients were diverted at the time of IPAA creation. Fourteen patients (15%) were readmitted, and reasons for readmission included bowel obstruction (n = 9; 64%), dehydration (n = 2; 14%), anastomotic leak (n = 2; 14%), and gastrointestinal (GI) bleeding (n = 1; 6%). Patients with a diverting ileostomy at the time of IPAA were more often readmittted than patients who were not diverted (21% vs 3%, p = 0.03). Further, 10 (71%) of the readmitted patients had complications attributable to their ileostomy. In patients readmitted for obstructive symptoms, six (67%) required red rubber catheter insertion for resolution, two (22%) patients required reoperation for obstructions at the level of the stoma, and one (11%) resolved with bowel rest alone. CONCLUSION: Readmission following IPAA creation in children is often secondary to preventable issues related to diverting ileostomy. Surgeons should carefully consider the necessity of diversion. When it is necessary, particular attention to fascial aperture size and post-discharge initiatives to reduce dehydration may reduce readmission rates. LEVEL OF EVIDENCE: Level III.

Early Hospital Discharge After Helicopter Transport of Pediatric Trauma Patients: Analysis of Rates of Over and Undertriage.

OBJECTIVES: Helicopter air ambulance (HAA) of pediatric trauma patients is a life-saving intervention. Triage remains a challenge for both scene transport and interhospital transfer of injured children. We aimed to understand whether overtriage or undertriage was a feature of scene or interhospital transfer and how in or out of state transfers affected these rates. METHODS: Children (<18 years) who underwent trauma activation at a level I trauma center between 2011 and 2013 were identified and reviewed. Patients transported by HAA were compared with those transported by ground ambulance (GA). RESULTS: Of 399 pediatric patients (median age, 10.4 years; range, 0.1-17 years; 264 male [66%]), 71 (18%) were transported by HAA. Seventy-two percent of HAA patients went to the intensive care unit or the operating room from the trauma bay or suffered in-hospital mortality (vs 42% GA, P < 0.001). More patients were overtriaged (HAA with injury severity score [ISS] of <15) from interhospital transfers than from the scene (25% vs 3%, P = 0.002). Undertriage (GA with ISS >15) was acceptable at 5% from the scene and 14% from interhospital transfers (P = 0.08). Overtriage of patients with ISS less than 15 to HAA was significantly lower from in-state hospitals (22%) than out-of-state hospitals (45%) (P = 0.02). Undertriage of patients with ISS greater than 15 to GA was also lower from in-state hospitals (20%) versus out-of-state hospitals (38%) (P = 0.03). CONCLUSIONS: Triage of pediatric trauma patients to HAA remains difficult. There remains potential for improvement, particularly as regards interhospital HAA overtriage, but well developed transfer protocols (such in-state protocols) may help.

North American pediatric surgery fellows' preparedness for humanitarian surgery.

INTRODUCTION: The overwhelming burden of pediatric surgical need in humanitarian settings has prompted mutual interest between humanitarian organizations and pediatric surgeons. To assess adequate fit, we correlated pediatric surgery fellowship case mix and load with acute pediatric surgical relief efforts in conflict and disaster zones. METHODS: We reviewed pediatric (age < 18) cases logged by the Médecins Sans Frontières Operational Centre Brussels (MSF-OCB) from a previously validated and published database spanning 2008-2014 and cases performed by American College of Graduate Medical Education (ACGME) pediatric surgery graduates from 2008 to 2018. Non-operative management for trauma, endoscopic procedures, and basic wound care were excluded as they were not tracked in either dataset. ACGME procedures were classified under 1 of 32 MSF pediatric surgery procedure categories and compared using chi-squared tests. RESULTS: ACGME fellows performed procedures in 44% of tracked MSF-OCB categories. Major MSF-OCB pediatric cases were comprised of 62% general surgery, 23% orthopedic surgery, 9% obstetrical surgery, 3% plastic/reconstructive surgery, 2% urogynecologic surgery, and 1% specialty surgery. In comparison, fellows' cases were 95% general surgery, 0% orthopedic surgery, 0% obstetrical surgery, 5% urogynecologic surgery, and 1% specialty surgery. Fellows more frequently performed abdominal, thoracic, other general surgical, urology/gynecologic, and specialty procedures, but performed fewer wound and burn procedures (all p < 0.05). Fellows received no experience in Cesarean section or open fracture repair. Fellows performed a greater proportion of surgeries for congenital conditions (p < 0.05). CONCLUSION: While ACGME pediatric surgical trainees receive significant training in general and urogynecologic surgical techniques, they lack sufficient case load for orthopedic and obstetrical care - a common need among children in humanitarian settings. Trainees and program directors should evaluate the fellow's role and scope in a global surgery rotation or provide advanced preparation to fill these gaps. Upon graduation, pediatric surgeons interested in humanitarian missions should seek out additional orthopedic and obstetrical training, or select missions that do not require such skillsets.

Adrenalectomy for non-neuroblastic pathology in children.

BACKGROUND: Adrenalectomy for non-neuroblastic pathologies in children is rare with limited data on outcomes. We reviewed our experience of adrenalectomy in this unique population. METHODS: Retrospective study of children (age ≤ 18) who underwent adrenalectomy with non-neuroblastic pathology from 1988 to 2018. Clinical and operative details of patients were abstracted. Outcomes included length of stay and 30-day postoperative morbidity. RESULTS: Forty children underwent 50 adrenalectomies (12 right-sided, 18 left-sided, 10 bilateral). Six patients (15%) presented with an incidental adrenal mass while 4 (10%) had masses found on screening for genetic mutations or prior malignancy. The remaining 30 (75%) presented with symptoms of hormonal excess. Nineteen patients (48%) underwent genetic evaluation and 15 (38%) had genetic predispositions. Diagnoses included 9 patients (23%) with pheochromocytoma, 8 (20%) with adrenocortical adenoma, 8 (20%) with adrenocortical carcinoma, 7 (18%) with adrenal hyperplasia, 2 (5%) with metastasis, and 6 (14%) with additional benign pathologies. Of 50 adrenalectomies, twenty-five (50%) were laparoscopic. Median hospital length of stay was 3 days (range 0-11). Post-operative morbidity rate was 17% with the most severe complication being Clavien-Dindo grade II. CONCLUSION: Adrenalectomy for non-neuroblastic pathology can be done with low morbidity. Its frequent association with genetic mutations and syndromes requires surgeons to have knowledge of appropriate pre-operative testing and post-operative surveillance.

Utilization of age-adjusted shock index in a resource-strained setting.

BACKGROUND: Identification of injury severity and appropriate triage are critical to effective surgical care, especially where medical and surgical resources are strained. We hypothesized that pediatric age-adjusted shock index (SIPA) would outperform traditional shock index (SI) in a middle-income country (MIC) setting. METHODS: Injured children hospitalized in two trauma centers (South Africa and the United States) from 2012 to 2017 were reviewed. Maximum heart rate and minimum systolic blood pressure defined SI. SI > 0.9 defined elevation. SIPA elevation was based on SI stratified by age: 1-6 years (SI > 1.22), 7-12 years (SI > 1.0), and 13-17 years (SI > 0.9). SI and SIPA were compared using univariate analyses and area under the receiver operating characteristic curves (AUROC). RESULTS: 1648 patients (741 MIC and 907 high-income country (HIC)) were evaluated with a median [IQR] age of 11 [6-15] years. SI was elevated in 377 (51%) MIC children, whereas SIPA was elevated in 248 (34%). In both the HIC and MIC, elevated SIPA was more associated with ISS ≥ 25, ICU admission, and mortality. In MIC patients specifically, elevated SIPA improved discrimination for in-hospital mortality (AUROC 0.66 vs AUROC 0.57, p < 0.01). CONCLUSION: In a multinational cohort including MIC patients, SIPA facilitated identification of injured children with altered physiology, reflecting greater injury severity and poorer outcomes. Use of SIPA has the potential for more effective resource utilization in MICs. LEVEL OF EVIDENCE: Level III.
