RESUMEN
This is a case of a neonate with suspected duodenal atresia on prenatal imaging. However, distal bowel gas was identified postnatally on regular X-rays with a possible pyloric obstructing mass visualised on ultasound. No contrast was visualised passing through the stomach on fluoroscopic studies. Operative evaluation revealed an atypical asymmetric hypertrophic pylorus with exophytic lesions of ectopic glandular tissue. Longitudinal open pyloromyotomy was performed which relieved the gastric obstruction resulting in symptomatic relief without any anatomy altering procedure required.

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.

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: 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.

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: Persistent Gastrocutaneous Fistula (GCF) is common problem encountered in the pediatric population. Several management options for intervening on pediatric persistent GCF have been described and range from open surgical management to medical management. Here we describe a novel adaptation on a previously described technique that utilizes a punch biopsy to excise the GCF we have coined as Punch Excision of Epithelialized Tracts (PEET). METHODS: The steps to this procedure include passing a punch biopsy tool over a Foley catheter. The catheter is inserted into the GCF tract, the balloon is inflated, the catheter is retracted against the abdominal wall, and the punch biopsy instrument is pushed through the skin and subcutaneous tissue circumferentially excising the tract. RESULTS: Four patients at our institution have undergone GCF excision using the PEET approach. Mean duration of the GCF in our four patients was 9 months. Mean follow-up after GCF excision using the PEET approach was 7.8 months. No patients in the cohort had any post-operative complications including surgical site wound infection, emergency department visits, or re-hospitalizations related to their surgical care. CONCLUSION: Based on our preliminary findings in this small patient cohort, we believe the PEET approach for managing persistent pediatric GCF has short-term efficacy and has the potential upside of utilizing fewer hospital resources to perform the procedure in a time-efficient manner.

This study presents the technique of percutaneous wire-target access of the superior vena cava (SVC) in patients with bilateral jugular-subclavian vein occlusion requiring a tunneled hemodialysis catheter. A 3-year retrospective review of five patients was performed. The femoral vein is accessed percutaneously and a 5F sheath inserted. This is followed by placement of a pigtail catheter (wire-target) in the SVC with cavography. The SVC is percutaneously cannulated at the level of the pigtail under fluoroscopy, and a guidewire is passed into the vena cava with confirmation by injection of contrast material. A tunneled hemodialysis catheter is then placed. The wire-target technique of SVC access can be used safely and effectively to establish upper body catheter access when traditional techniques are not possible.
RESUMEN
PURPOSE: No consensus guidelines exist for timing of enterostomy closure in neonatal isolated intestinal perforation (IIP). This study evaluated neonates with IIP closed during the initial admission (A1) versus a separate admission (A2) comparing total length of stay and total hospital cost. METHODS: Using 2012 to 2017 Pediatric Health information System (PHIS) data, 359 neonates with IIP were identified who underwent enterostomy creation and enterostomy closure. Two hundred sixty-five neonates (A1) underwent enterostomy creation and enterostomy closure during the same admission. Ninety-four neonates (A2) underwent enterostomy creation at initial admission and enterostomy closure during subsequent admission. For the A2 neonates, total hospital length of stay was calculated as the sum of hospital days for both admissions. A1 neonates were matched to A2 neonates in a 1:1 ratio using propensity score matching. Multivariate models were used to compare the two matched pair groups for length of stay and cost comparisons. RESULTS: Prior to matching, the basic demographics of our study population included a median birthweight of 960â¯g, mean gestational age of 29.5â¯weeks, and average age at admission of 4â¯days. Eighty-seven pairs of neonates with IIP were identified during the matching process. Neonates in A2 had 91% shorter total hospital length of stay compared to A1 neonates (HR: 1.91; 95% CI for HR: 1.44-2.53; pâ¯<â¯.0001). The median length of stay for A1 was 95â¯days (95% CI: 78-102â¯days) versus A2 length of stay of 67â¯days (95% CI: 56-76â¯days). Adjusting for the same covariates, A2 neonates had a 22% reduction in the average total cost compared A1 neonates (RR: 0.78; 95% CI for RR: 0.64-0.95; p-valueâ¯=â¯0.014). The average total costs were $245,742.28 for A2 neonates vs. $315,052.21 for A1 neonates (pâ¯<â¯0.001). CONCLUSION: Neonates with IIP have a 28â¯day shorter hospital length of stay, $75,000 or 24% lower total hospital costs, and a 22â¯day shorter post-operative course following enterostomy closure when enterostomy creation and closure is performed on separate admissions. TYPE OF STUDY: Prognosis Study. LEVEL OF EVIDENCE: Level II.

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.

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.

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.

PURPOSE: The low perioperative mortality rate in pediatric surgery precludes effective analysis of mortality at individual institutions. Therefore, analysis of multi-institutional data is essential to determine any patterns of perioperative death in children. The aim of this study was to determine diagnoses associated with 24-hour and 30-day perioperative mortality. METHODS: A retrospective review of the 2012-2015 Pediatric Participant Use Data File (PUF) was performed. Statistical comparisons were made between survivors and nonsurvivors and between those with 24-hour and 30-day mortality using Fischer's exact tests. P-values ≤ 0.05 were considered significant. RESULTS: 103,444 patients who underwent a pediatric surgical operation were evaluated. There were 732 deaths with a 30-day perioperative mortality of 0.7% (732/103,444). Necrotizing enterocolitis (NEC) was the diagnosis associated with the highest 30-day perioperative mortality (175/901, 19%). A significantly higher proportion NEC deaths occurred in the first 24 hours (67% (118/175) vs 33% (57/175) 30 day mortality, p<0.001). Compared to patients who survived following operation for NEC, those who died were statistically more likely to require inotropic support (56% vs. 15%, p<0.001), be diagnosed with sepsis (52% vs. 22%, p < 0.001), and undergo blood transfusion within 48 hours of operation (49% vs. 34%, p<0.001). CONCLUSION: Although the overall pediatric surgical operative mortality rate is low, the largest proportion of perioperative deaths occur secondary to NEC. Based on the high immediate mortality, optimization of operative care for septic patients with NEC should be targeted. TYPE OF STUDY: Prognosis Study LEVEL OF EVIDENCE: Level II.

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.

PURPOSE: Pediatric surgeon performed bedside ultrasound (PSPBUS) is a targeted examination that is diagnostic or therapeutic. The aim of this paper is to review literature involving PSPBUS. METHODS: PSPBUS practices reviewed in this paper include central venous catheter placement, physiologic assessment (volume status and echocardiography), hypertrophic pyloric stenosis diagnosis, appendicitis diagnosis, the Focused Assessment with Sonography for Trauma (FAST), thoracic evaluation, and soft tissue infection evaluation. RESULTS: There are no standards for the practice of PSPBUS. CONCLUSIONS: As the role of the pediatric surgeon continues to evolve, PSPBUS will influence practice patterns, disease diagnosis, and patient management. TYPE OF STUDY: Review Article.

This report presents an unusual case of traumatic iliofemoral vessel transection in a 3-year-old patient successfully reconstructed using a cryopreserved greater saphenous conduit. Five years after injury, the patient continues to do well with normal ambulation. An arterial duplex demonstrated graft patency free of aneurysmal dilatation. These encouraging results suggest that the natural history of cryopreserved conduits may differ in the pediatric population and cryopreserved conduits could be used for complex vascular reconstructions.

The purpose of this technological notes paper is to describe our institution's experience collecting peripheral venous pressure (PVP) waveforms using a standard peripheral intravenous catheter in an awake pediatric patient. PVP waveforms were collected from patients with hypertrophic pyloric stenosis. PVP measurements were obtained prospectively at two time points during the hospitalization: admission to emergency department and after bolus in emergency department. Data was collected from thirty-two patients. Interference in the PVP waveforms data collection was associated with the following: patient or device motion, system set-up error, type of IV catheter, and peripheral intravenous catheter location. PVP waveforms can be collected in an awake pediatric patient and adjuncts to decrease signal interference can be used to optimize data collection.

BACKGROUND: Variation exists in pediatric vascular trauma management. We aim to determine practice patterns for vascular trauma management at American College of Surgeons verified pediatric trauma centers and evaluate the resources available for management of vascular trauma at both freestanding children's hospitals (FSCH) and pediatric hospitals within general adult hospitals. METHODS: Pediatric surgeons and trauma medical directors at American College of Surgeons designated pediatric surgery trauma centers completed a survey designed to evaluate anticipated management of traumatic arterial injuries and resource availability. Hospital setting comparisons were made using Fisher exact tests and t tests. Binomial tests were used to compare pediatric and vascular surgeons' responses to clinical vignettes. p Values of 0.05 or less were significant. RESULTS: One hundred seventy-six (42%) of 414 pediatric surgeons participated. Vascular surgeons are more likely to operatively manage vascular trauma at all anatomic sites except subclavian artery when compared to pediatric surgeons, regardless of hospital setting (p <0.001). Forty-eight percent of the pediatric trauma medical directors completed their portion of the survey. At FSCHs, 36% did not have a fellowship-trained vascular surgeon on-call schedule, 27% did not have endovascular capabilities, and 18% did not have a radiology technologist always available. CONCLUSION: Vascular surgeons are more likely to manage pediatric vascular trauma regardless of hospital setting. However, FSCH have fewer resources available to provide optimal care. LEVEL OF EVIDENCE: Care management, level IV.
