RESUMEN
Importance: Inguinal hernia repair in preterm infants is common and is associated with considerable morbidity. Whether the inguinal hernia should be repaired prior to or after discharge from the neonatal intensive care unit is controversial. Objective: To evaluate the safety of early vs late surgical repair for preterm infants with an inguinal hernia. Design, Setting, and Participants: A multicenter randomized clinical trial including preterm infants with inguinal hernia diagnosed during initial hospitalization was conducted between September 2013 and April 2021 at 39 US hospitals. Follow-up was completed on January 3, 2023. Interventions: In the early repair strategy, infants underwent inguinal hernia repair before neonatal intensive care unit discharge. In the late repair strategy, hernia repair was planned after discharge from the neonatal intensive care unit and when the infants were older than 55 weeks' postmenstrual age. Main Outcomes and Measures: The primary outcome was occurrence of any prespecified serious adverse event during the 10-month observation period (determined by a blinded adjudication committee). The secondary outcomes included the total number of days in the hospital during the 10-month observation period. Results: Among the 338 randomized infants (172 in the early repair group and 166 in the late repair group), 320 underwent operative repair (86% were male; 2% were Asian, 30% were Black, 16% were Hispanic, 59% were White, and race and ethnicity were unknown in 9% and 4%, respectively; the mean gestational age at birth was 26.6 weeks [SD, 2.8 weeks]; the mean postnatal age at enrollment was 12 weeks [SD, 5 weeks]). Among 308 infants (91%) with complete data (159 in the early repair group and 149 in the late repair group), 44 (28%) in the early repair group vs 27 (18%) in the late repair group had at least 1 serious adverse event (risk difference, -7.9% [95% credible interval, -16.9% to 0%]; 97% bayesian posterior probability of benefit with late repair). The median number of days in the hospital during the 10-month observation period was 19.0 days (IQR, 9.8 to 35.0 days) in the early repair group vs 16.0 days (IQR, 7.0 to 38.0 days) in the late repair group (82% posterior probability of benefit with late repair). In the prespecified subgroup analyses, the probability that late repair reduced the number of infants with at least 1 serious adverse event was higher in infants with a gestational age younger than 28 weeks and in those with bronchopulmonary dysplasia (99% probability of benefit in each subgroup). Conclusions and Relevance: Among preterm infants with inguinal hernia, the late repair strategy resulted in fewer infants having at least 1 serious adverse event. These findings support delaying inguinal hernia repair until after initial discharge from the neonatal intensive care unit. Trial Registration: ClinicalTrials.gov Identifier: NCT01678638.

BACKGROUND: The benefit of targeting high ratio fresh frozen plasma (FFP):red blood cell (RBC) transfusion in pediatric trauma resuscitation is unclear as existing studies are limited to patients who retrospectively met criteria for massive transfusion. The purpose of this study is to evaluate the use of high ratio FFP:RBC transfusion and the association with outcomes in children presenting in shock. METHODS: A post-hoc analysis of a 24-institution prospective observational study (4/2018-9/2019) of injured children <18 years with elevated age-adjusted shock index was performed. Patients transfused within 24 hours were stratified into cohorts of low (<1:2) or high (>1:2) ratio FFP:RBC. Nonparametric Kruskal-Wallis and chi-square were used to compare characteristics and mortality. Competing risks analysis was used to compare extended (≥75th percentile) ventilator, intensive care, and hospital days while accounting for early deaths. RESULTS: Of 135 children with median (IQR) age 10 (5,14) years and weight 40 (20,64) kg, 85 (63%) received low ratio transfusion and 50 (37%) high ratio despite similar activation of institutional massive transfusion protocols (MTP; low-38%, high-46%, p = .34). Most patients sustained blunt injuries (70%). Median injury severity score was greater in high ratio patients (low-25, high-33, p = .01); however, hospital mortality was similar (low-24%, high-20%, p = .65) as was the risk of extended ventilator, ICU, and hospital days (all p > .05). CONCLUSION: Despite increased injury severity, patients who received a high ratio of FFP:RBC had comparable rates of mortality. These data suggest high ratio FFP:RBC resuscitation is not associated with worst outcomes in children who present in shock. MTP activation was not associated with receipt of high ratio transfusion, suggesting variability in MTP between centers. LEVEL OF EVIDENCE: Prospective cohort study, Level II.
RESUMEN
OBJECTIVES: Variability in opioid-prescribing practices after common pediatric surgical procedures at our institution prompted the development of opioid-prescribing guidelines that provided suggested dose limitations for narcotics. The aims of this study were to improve opioid prescription practices through implementation of the developed guidelines and to assess compliance and identify barriers preventing guideline utilization. METHODS: We conducted a single-center cohort study of all children who underwent the most common outpatient general surgery procedures at our institution from August 1, 2018, to February 1, 2020. We created guidelines designed to limit opioid prescription doses based on data obtained from standardized postoperative telephone interviews. Three 6-month periods were evaluated: before guideline implementation, after guideline initiation, and after addressing barriers to guideline compliance. Targeted interventions to increase compliance included modification of electronic medical record defaults and provider educations. Differences in opioid weight-based doses prescribed, filled, and taken, as well as protocol adherence between the 3 timeframes were evaluated. RESULTS: A total of 1033 children underwent an outpatient procedure during the 1.5-year time frame. Phone call response rate was 72.22%. There was a significant sustained decrease in opioid doses prescribed ( P < 0.0001), prescriptions filled ( P = 0.009), and opioid doses taken ( P = 0.001) after implementation, without subsequent increase in reported pain on postoperative phone call ( P = 0.96). Protocol compliance significantly improved (62.39% versus 83.98%, P < 0.0001) after obstacles were addressed. CONCLUSIONS: Implementation of a protocol limiting opioid prescribing after frequently performed pediatric general surgery procedures reduced opioids prescribed and taken postoperatively. Interventions that addressed barriers to application led to increased protocol compliance and sustained decreases in opioids prescribed and taken without a deleterious effect on pain control.

OBJECTIVE: This study examined differences in clinical and resuscitation characteristics between injured children with and without severe traumatic brain injury (sTBI) and aimed to identify resuscitation characteristics associated with improved outcomes following sTBI. METHODS: This is a post hoc analysis of a prospective observational study of injured children younger than 18 years (2018-2019) transported from the scene, with elevated shock index pediatric-adjusted on arrival and head Abbreviated Injury Scale score of ≥3. Timing and volume of resuscitation products were assessed using χ 2t test, Fisher's exact t test, Kruskal-Wallis, and multivariable logistic regression analyses. RESULTS: There were 142 patients with sTBI and 547 with non-sTBI injuries. Severe traumatic brain injury patients had lower initial hemoglobin (11.3 vs. 12.4, p < 0.001), greater initial international normalized ratio (1.4 vs. 1.1, p < 0.001), greater Injury Severity Score (25 vs. 5, p < 0.001), greater rates of ventilator (59% vs. 11%, p < 0.001) and intensive care unit (ICU) requirement (79% vs. 27%, p < 0.001), and more inpatient complications (18% vs. 3.3%, p < 0.001). Severe traumatic brain injury patients received more prehospital crystalloid (25% vs. 15%, p = 0.008), ≥1 crystalloid boluses (52% vs. 24%, p < 0.001), and blood transfusion (44% vs. 12%, p < 0.001) than non-sTBI patients. Among sTBI patients, receipt of ≥1 crystalloid bolus (n = 75) was associated with greater ICU need (92% vs. 64%, p < 0.001), longer median ICU (6 vs. 4 days, p = 0.027) and hospital stay (9 vs. 4 days, p < 0.001), and more in-hospital complications (31% vs. 7.5%, p = 0.003) than those who received <1 bolus (n = 67). These findings persisted after adjustment for Injury Severity Score (odds ratio, 3.4-4.4; all p < 0.010). CONCLUSION: Pediatric trauma patients with sTBI received more crystalloid than those without sTBI despite having a greater international normalized ratio at presentation and more frequently requiring blood products. Excessive crystalloid may be associated with worsened outcomes, including in-hospital mortality, seen among pediatric sTBI patients who received ≥1 crystalloid bolus. Further attention to a crystalloid sparing, early transfusion approach to resuscitation of children with sTBI is needed. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

INTRODUCTION: Sepsis prevention pathways, which often include blood and urine cultures, are common in children's hospitals. Fever and tachycardia, signs often seen in patients with appendicitis, frequently trigger these pathways. We hypothesized that cultures were frequently obtained in children with appendicitis. MATERIALS AND METHODS: We conducted a single-center retrospective cohort study evaluating children with image-confirmed appendicitis from 4/1/2019 to 10/1/2020, coinciding with the initiation of sepsis prevention pathways. Factors associated with culture acquisition, as well as culture results, treatment, and outcomes were evaluated. RESULTS: Six hundred and fifty eight children presented with acute appendicitis during the 1.5-year period, with a median age of 10.67 years (interquartile range (IQR) 8.17-14.08). Cultures were obtained in 22.9%, including blood culture (BCx) in 8.1% and urine culture (UCx) in 17.9%. Culture acquisition decreased by 17.6% after sepsis protocol initiation. Blood culture acquisition correlated with fever (P = .003) and younger age (P = .03), whereas the attainment of BCx and UCx was associated with female sex (P = .04, P < .0001), complicated appendicitis (P = .0001, P = .03), and unknown diagnosis (P < .0001, P < .0001). There were five positive UCx (4.24%); however, all remained asymptomatic despite a short antibiotic duration dictated by institutional appendicitis protocol. The one positive BCx (1.89%) was suspected contamination and not treated. DISCUSSION: The findings of this cohort suggest a low incidence of positive culture as well as lack of impact on clinical management in image-proven appendicitis and the initiation of a sepsis bundle without automatic culture acquisition may result in decreased culture attainment.

BACKGROUND: The COVID-19 pandemic has impacted timely access to care for children, including patients with appendicitis. This study aimed to evaluate the effect of the COVID-19 pandemic on management of appendicitis and patient outcomes. METHODS: A multicenter retrospective study was performed including 19 children's hospitals from April 2019-October 2020 of children (age≤18 years) diagnosed with appendicitis. Groups were defined by each hospital's city/state stay-at-home orders (SAHO), designating patients as Pre-COVID (Pre-SAHO) or COVID (Post-SAHO). Demographic, treatment, and outcome data were obtained, and univariate and multivariable analysis was performed. RESULTS: Of 6,014 patients, 2,413 (40.1%) presented during the COVID-19 pandemic. More patients were managed non-operatively during the COVID-19 pandemic compared to before the pandemic (147 (6.1%) vs 144 (4.0%), p < 0.001). Despite this change, there was no difference in the proportion of complicated appendicitis between groups (1,247 (34.6%) vs 849 (35.2%), p = 0.12). COVID era non-operative patients received fewer additional procedures, including interventional radiology (IR) drain placements, compared to pre-COVID non-operative patients (29 (19.7%) vs 69 (47.9%), p < 0.001). On adjusted analysis, factors associated with increased odds of receiving non-operative management included: increasing duration of symptoms (OR=1.01, 95% CI: 1.01-1.012), African American race (OR=2.4, 95% CI: 1.3-4.6), and testing positive for COVID-19 (OR=10.8, 95% CI: 5.4-21.6). CONCLUSION: Non-operative management of appendicitis increased during the COVID-19 pandemic. Additionally, fewer COVID era cases required IR procedures. These changes in the management of pediatric appendicitis during the COVID pandemic demonstrates the potential for future utilization of non-operative management.

Blue Rubber Bleb Nevus Syndrome is a congenital rarity that manifests as vascular malformations throughout the body, including the gastrointestinal tract. With fewer than 300 cases reported, the etiology and clinical course is poorly understood; however, the literature suggests TEK mutations on chromosome 9 result in unregulated angiogenesis. We present the case of a young female treated for anemia of unknown etiology who presented in hemorrhagic shock due to gastrointestinal hemorrhage necessitating small bowel resection, with cutaneous, intestinal, hepatic, and lingual vascular malformations associated with a single somatic pathologic TEK mutation. Although uncommon, this case suggests that Blue Rubber Bleb Nevus Syndrome should be considered in the differential of a patient with persistent anemia and cutaneous lesions, carrying the potential for multiple gastrointestinal vascular malformations progressing to hemorrhage necessitating operative management. Additionally, a severe phenotype can occur without a double-hit TEK mutation.

BACKGROUND: While it is assumed adolescents receive comparable trauma care at pediatric trauma centers (PTC), adult trauma centers (ATC), and combined facilities (MTC), this remains understudied. METHODS: We conducted a retrospective cohort study through the NTDB evaluating patients 14-18 years of age who presented to an ACS-verified level 1 or 2 trauma facility between 1/1/2016 and 12/31/2019. Multiple logistic regression analyses were performed to compare mortality risk among trauma facility verification types. RESULTS: 91,881 adolescents presented after trauma over the four-years. Hypotension, severe TBI, firearm mechanism, and ISS >15 were associated with increased mortality. Compared to PTCs, the odds of trauma-related mortality were statistically higher at MTCs (OR 1.82, p = 0.004) and ATCs (OR 1.89-2.05, p = 0.001-0.002). CONCLUSIONS: Injured adolescents receiving care at ATCs and MTCs have higher mortality risk than those cared for at PTCs. Further evaluation of factors associated with this observed difference is warranted and may help identify opportunities to improve outcomes in injured adolescents.

BACKGROUND: Persistent gastrocutaneous fistulae frequently complicate gastrostomy tube placement. A minimally invasive technique for tract closure employing balloon catheter retraction and punch excision of the epithelized tract (PEET) was recently reported. We hypothesized the PEET technique of closure would lead to decreased complications without an increased incidence of recurrence. METHODS: We conducted a single-center retrospective cohort study evaluating children who underwent gastrocutaneous fistula (GCF) closure 1/1/2018-12/31/2021, comparing patients who underwent the PEET procedure to those repaired with layered closure. Procedure duration and outcomes were additionally compared to the 2018-2019 National Surgical Quality Improvement Program (NSQIP) Participant Use File (PUF) database. RESULTS: Sixty-two children underwent operative GCF closure, including 25 with PEET and 37 traditional layered closure. Procedural time was significantly decreased employing PEET (14 vs 26 minutes, P < .0001), less than half the national median by the NSQIP PUF database of 292 GCF closures (14 vs 34.5 minutes, P < .0001). Those repaired with the PEET method experienced no episodes of recurrence, surgical site infection, readmission, reoperation, or mortality within 30 days of the procedure. Conversely, in traditional closure, there was a 24.3% complication rate, including 7 surgical site infections, 1 readmission, and 2 unplanned reoperations. National procedural complication rate by NSQIP PUF was 5.5%, with a 4.8% rate of surgical site infection, .3% reoperation incidence, and .3% mortality. DISCUSSION: Our study suggests GCF closure employing the PEET procedure is a safe, more efficient method of tract closure than the traditional layered closure technique.

BACKGROUND: Pediatric trauma patients sustaining blunt abdominal trauma (BAT) with intra-abdominal injury (IAI) are frequently admitted to the intensive care unit (ICU). This study was performed to identify predictors for ICU admission following BAT. METHODS: Prospective study of children (< 16 years) who presented to 14 Level-One Pediatric Trauma Centers following BAT over a 1-year period. Patients were categorized as ICU or non-ICU patients. Data collected included vitals, physical exam findings, laboratory results, imaging, and traumatic injuries. A multivariable hierarchical logistic regression model was used to identify predictors of ICU admission. Predictive ability of the model was assessed via tenfold cross-validated area under the receiver operating characteristic curves (cvAUC). RESULTS: Included were 2,182 children with 21% (n = 463) admitted to the ICU. On univariate analysis, ICU patients were associated with abnormal age-adjusted shock index, increased injury severity scores (ISS), lower Glasgow coma scores (GCS), traumatic brain injury (TBI), and severe solid organ injury (SOI). With multivariable logistic regression, factors associated with ICU admission were severe trauma (ISS > 15), anemia (hematocrit < 30), severe TBI (GCS < 8), cervical spine injury, skull fracture, and severe solid organ injury. The cvAUC for the multivariable model was 0.91 (95% CI 0.88-0.92). CONCLUSION: Severe solid organ injury and traumatic brain injury, in association with multisystem trauma, appear to drive ICU admission in pediatric patients with BAT. These results may inform the design of a trauma bay prediction rule to assist in optimizing ICU resource utilization after BAT. STUDY DESIGN: Prognosis study.

Analysis of peripheral venous pressure (PVP) waveforms is a novel method of monitoring intravascular volume. Two pediatric cohorts were studied to test the effect of anesthetic agents on the PVP waveform and cross-talk between peripheral veins and arteries: (1) dehydration setting in a pyloromyotomy using the infused anesthetic propofol and (2) hemorrhage setting during elective surgery for craniosynostosis with the inhaled anesthetic isoflurane. PVP waveforms were collected from 39 patients that received propofol and 9 that received isoflurane. A multiple analysis of variance test determined if anesthetics influence the PVP waveform. A prediction system was built using k-nearest neighbor (k-NN) to distinguish between: (1) PVP waveforms with and without propofol and (2) different minimum alveolar concentration (MAC) groups of isoflurane. 52 porcine, 5 propofol, and 7 isoflurane subjects were used to determine the cross-talk between veins and arteries at the heart and respiratory rate frequency during: (a) during and after bleeding with constant anesthesia, (b) before and after propofol, and (c) at each MAC value. PVP waveforms are influenced by anesthetics, determined by MANOVA: p value < 0.01, η2 = 0.478 for hypovolemic, and η2 = 0.388 for euvolemic conditions. The k-NN prediction models had 82% and 77% accuracy for detecting propofol and MAC, respectively. The cross-talk relationship at each stage was: (a) ρ = 0.95, (b) ρ = 0.96, and (c) could not be evaluated using this cohort. Future research should consider anesthetic agents when analyzing PVP waveforms developing future clinical monitoring technology that uses PVP.

BACKGROUND: Postoperative oral antibiotic management at discharge for perforated appendicitis varies by institution. A prior study at our institution led to a decrease in antibiotic therapy in patients without leukocytosis. A subsequent protocol change eliminated the white blood cell count check and oral antibiotics if discharge criteria were met by postoperative day seven. We hypothesized this change could be made without an increase in abscess or readmission rates. METHODS: We conducted a retrospective review of patients with perforated appendicitis over two 1-year periods after institutional review board approval (262061). In the pre-protocol group, a white blood cell count was checked at discharge and patients with leukocytosis were prescribed oral antibiotics to complete a total of 7 d. In the post-protocol group, no white blood cell count was checked and patients were discharged home without antibiotics. RESULTS: There were a total of 174 patients with complicated appendicitis in the two 1-year periods with 129 (74%) patients with perforated appendicitis discharged before postoperative day seven. The pre-protocol group included 71 children, and post-protocol included 58 children. There were no differences between mean postoperative days to discharge (2.57 versus 3, P = 0.0896), postoperative abscess rate (12.7% versus 12.1%, P = 1.0000), or readmission rate (12.7% versus 17.2%, P = 0.6184). None of the patients in the post-protocol group were discharged home with oral antibiotics compared with 22.5% in the pre-protocol group (P < 0.001). CONCLUSIONS: For pediatric patients with perforated appendicitis discharged before postoperative day seven, stopping antibiotics at the time of discharge significantly decreased our home antibiotic use without an increase in postoperative morbidity.

BACKGROUND: The purpose of this study was to determine the relationship between timing and volume of crystalloid before blood products and mortality, hypothesizing that earlier transfusion and decreased crystalloid before transfusion would be associated with improved outcomes. METHODS: A multi-institutional prospective observational study of pediatric trauma patients younger than 18 years, transported from the scene of injury with elevated age-adjusted shock index on arrival, was performed from April 2018 to September 2019. Volume and timing of prehospital, emergency department, and initial admission resuscitation were assessed including calculation of 20 ± 10 mL/kg crystalloid boluses overall and before transfusion. Multivariable Cox proportional hazards and logistic regression models identified factors associated with mortality and extended intensive care, ventilator, and hospital days. RESULTS: In 712 children at 24 trauma centers, mean age was 7.6 years, median (interquartile range) Injury Severity Score was 9 (2-20), and in-hospital mortality was 5.3% (n = 38). There were 311 patients(43.7%) who received at least one crystalloid bolus and 149 (20.9%) who received blood including 65 (9.6%) with massive transfusion activation. Half (53.3%) of patients who received greater than one crystalloid bolus required transfusion. Patients who received blood first (n = 41) had shorter median time to transfusion (19.8 vs. 78.0 minutes, p = 0.005) and less total fluid volume (50.4 vs. 86.6 mL/kg, p = 0.033) than those who received crystalloid first despite similar Injury Severity Score (median, 22 vs. 27, p = 0.40). On multivariable analysis, there was no association with mortality (p = 0.51); however, each crystalloid bolus after the first was incrementally associated with increased odds of extended ventilator, intensive care unit, and hospital days (all p < 0.05). Longer time to transfusion was associated with extended ventilator duration (odds ratio, 1.11; p = 0.04). CONCLUSION: Resuscitation with greater than one crystalloid bolus was associated with increased need for transfusion and worse outcomes including extended duration of mechanical ventilation and hospitalization in this prospective study. These data support a crystalloid-sparing, early transfusion approach for resuscitation of injured children. LEVEL OF EVIDENCE: Therapeutic, level IV.

BACKGROUND: We implemented a protocol to evaluate pediatric patients with suspected appendicitis using ultrasound as the initial imaging modality. CT utilization rates and diagnostic accuracy were evaluated two years after pathway implementation. METHODS: This was a retrospective observational study of patients <18 years evaluated for suspected appendicitis. CT rates were compared before and after implementation of the protocol, and monthly CT rates were calculated to assess trends in CT utilization. RESULTS: CT use decreased significantly following pathway implementation from 94.2% (130/138) to 27.5% (78/284; pâ¯<â¯0.001). Linear regression of monthly CT utilization demonstrated that CT rates continued to trend down two years after pathway implementation. Adherence to the pathway was 89.8% (255/284). Negative appendectomy rate was 2.4% (2/85) in the post-pathway period. CONCLUSIONS: Adherence to a pathway designed to evaluate pediatric patients with suspected appendicitis using ultrasound as the primary imaging modality has led to a sustained decrease in CT use without compromising diagnostic accuracy.

Vital signs are included in the determination of shock secondary to hemorrhage; however, more granular predictors are needed. We hypothesized that fast Fourier transformation (FFT) would have a greater percent change after hemorrhage than heart rate (HR) or systolic blood pressure (SBP). Using a porcine model, nine 17 kg pigs were hemorrhaged 10% of their calculated blood volume. Peripheral venous pressure waveforms, HR and SBP were collected at baseline and after 10% blood loss. FFT was performed on the peripheral venous pressure waveforms and the peak between 1 and 3 hertz (f1) corresponded to HR. To normalize values for comparison, percent change was calculated for f1, SBP, and HR. The mean percent change for f1 was an 18.8% decrease; SBP was a 3.31% decrease; and HR was a 0.95% increase. Using analysis of variance, FFT at f1 demonstrates a statistically significant greater change than HR or SBP after loss of 10% of circulating blood volume (p = 0.0023). Further work is needed to determine if this could be used in field triage to guide resuscitation.

BACKGROUND: No standard dehydration monitor exists for children. This study attempts to determine the utility of Fast Fourier Transform (FFT) of a peripheral venous pressure (PVP) waveform to predict dehydration. MATERIALS AND METHODS: PVP waveforms were collected from 18 patients. Groups were defined as resuscitated (serum chloride ≥ 100 mmol/L) and hypovolemic (serum chloride < 100 mmol/L). Data were collected on emergency department admission and after a 20 cc/kg fluid bolus. The MATLAB (MathWorks) software analyzed nonoverlapping 10-s window signals; 2.4 Hz (144 bps) was the most demonstrative frequency to compare the PVP signal power (mmHg). RESULTS: Admission FFTs were compared between 10 (56%) resuscitated and 8 (44%) hypovolemic patients. The PVP signal power was higher in resuscitated patients (median 0.174 mmHg, IQR: 0.079-0.374 mmHg) than in hypovolemic patients (median 0.026 mmHg, IQR: 0.001-0.057 mmHg), (P < 0.001). Fourteen patients received a bolus regardless of laboratory values: 6 (43%) resuscitated and 8 (57%) hypovolemic. In resuscitated patients, the signal power did not change significantly after the fluid bolus (median 0.142 mmHg, IQR: 0.032-0.383 mmHg) (P = 0.019), whereas significantly increased signal power (median 0.0474 mmHg, IQR: 0.019-0.110 mmHg) was observed in the hypovolemic patients after a fluid bolus at 2.4 Hz (P < 0.001). The algorithm predicted dehydration for window-level analysis (sensitivity 97.95%, specificity 93.07%). The algorithm predicted dehydration for patient-level analysis (sensitivity 100%, specificity 100%). CONCLUSIONS: FFT of PVP waveforms can predict dehydration in hypertrophic pyloric stenosis. Further work is needed to determine the utility of PVP analysis to guide fluid resuscitation status in other pediatric populations.

BACKGROUND: Variation exists for postoperative antibiotics in children with complicated appendicitis. We investigated the impact of white blood count (WBC) at discharge on oral antibiotic therapy, abscess rate, and readmission rate. MATERIAL/METHODS: We conducted a two year review of children with complicated appendicitis. In the pre-protocol group, total antibiotic therapy was ten days (IV and oral) and home oral antibiotics at discharge. In the post-protocol group, children with leukocytosis were prescribed oral antibiotics to complete seven days of total antibiotic therapy and children without leukocytosis were not prescribed oral home antibiotics. RESULTS: There was no difference between mean hospital days after operation (3.52 vs. 3.24, pâ¯=â¯0.5111), means days of inpatient intravenous antibiotics (3.13 vs. 2.58, pâ¯=â¯0.5438), post-operative abscess rates (20.7% vs. 19.6%, pâ¯=â¯0.9975), or readmission rate (13.4% vs. 12.4%, pâ¯=â¯1.000). The post-protocol group had a shorter average total antibiotic duration (4.24 vs. 9.52 days, pâ¯<â¯0.001) and were more likely to be discharged without oral antibiotics (71.1% vs 8.5%, pâ¯<â¯0.001). DISCUSSION: Limiting home antibiotics at discharge to children with leukocytosis significantly decreases home antibiotic use.

BACKGROUND: Vascular surgeons infrequently care for pediatric patients. As such, variability in operative management and available hospital resources at free-standing children's hospitals (CHs) may exist. The study aims were (1) to determine vascular surgeon comfort level with pediatric vascular surgery and (2) to determine variations in pediatric vascular surgery practice patterns. METHODS: A survey composed of clinical vignettes emailed to all members of Vascular and Endovascular Surgery Society was designed to assess operative management of pediatric vascular conditions and hospital resources. Comparisons of surgeon satisfaction between free-standing CHs and a CH within an adult general hospital were made using Wilcoxon rank-sum tests. Comparison of surgeon comfort between hospital types was made using a McNemar's test. P-values less than or equal to 0.05 indicated statistical significance. RESULTS: Response rate was 18% (93/525) with 96% (89/93) indicating completion of a 2 year vascular fellowship. Surgeon satisfaction with operative equipment (P = 0.002), support staff (P < 0.001), and vascular laboratory availability (P = 0.01) was significantly lower at CHs. Eighty-seven percent of surgeons operated on fewer than 2 children over the preceding 3 months. For the different clinical vignettes, there was a wide variation in practice patterns with a range of 50-89% of the surgeons performing fewer than 5 cases over the preceding 10 years. There was a significant decrease in surgeon's comfort level with elective pediatric vascular operations compared to the operative management of pediatric vascular trauma (P = 0.0025). CONCLUSIONS: Most vascular surgeons do not feel comfortable in the operative management of pediatric vascular disease, and optimal resource availability within pediatric CHs may be lacking. Centralized care of this patient population may be warranted.

OBJECTIVES: Children with choledocholithiasis are frequently managed at tertiary children's hospitals that do not have available endoscopic retrograde cholangiopancreatography (ERCP) proceduralists. We hypothesized that patients treated at hospitals without ERCP proceduralists would have a longer hospital length of stay (LOS) than those with ERCP proceduralists. METHODS: Charts were reviewed for patients who underwent cholecystectomy and ERCP at 3 tertiary children's hospitals over 10 years. Trauma and complicated pancreatitis patients were excluded. Comparisons between patients requiring and not requiring transfer for ERCP were made using Wilcoxon rank-sum tests for continuous variables and Fisher's exact tests for categorical variables. RESULTS: One hundred and sixty-four children underwent ERCP for suspected choledocholithiasis: 79 (48%) in the transfer group and 85 (52%) in the no transfer group.Median LOS was longer for patients requiring transfer (7 vs 5 days, Pâ<â0.0001). One-third (34%) of the transfer patients had magnetic resonance cholangiopancreatography compared to only 7% that did not require transfer (Pâ<â0.0001). Among the 123 patients who underwent ERCP before cholecystectomy, 53% required (66/123) transfer and 47% (57/123) did not. Transfer group patients had longer median hospital LOS (Pâ<â0.0001), more days between admission and ERCP (Pâ<â0.0001), and more days between ERCP and surgery (Pâ=â0.0004). CONCLUSIONS: Overall median LOS was significantly shorter for patients who underwent ERCP at the admitting facility. Patients who underwent ERCP before cholecystectomy at hospitals without available ERCP proceduralists incurred longer LOS. There is a need for more pediatric proceduralists appropriately trained to perform ERCP in children.

This is a case with associated radiologic images for a pediatric patient who developed portomesenteric and splenic vein thrombosis (PMSVT) after Roux-en-Y gastric bypass with subsequent development of portal cavernoma and gallbladder varices (GBV). This case highlights both the importance of post-operative prophylactic anti-coagulation after gastric bypass and detailed imaging following a diagnosis of PMSVT. This case is relevant for pediatric surgeons as they are performing this operation more frequently with the increase in pediatric obesity.
