Surgical Outcomes In Children Research Articles

Surgical outcomes in children with drug-resistant epilepsy and hippocampal sclerosis

BackgroundHippocampal sclerosis (HS) is a common surgical substrate in adult epilepsy surgery cohorts but variably reported in various pediatric cohorts. ObjectiveWe aimed to study the epilepsy phenotype, radiological and pathological variability, seizure and neurocognitive outcomes in children with drug-resistant epilepsy and hippocampal sclerosis (HS) with or without additional subtle signal changes in anterior temporal lobe who underwent surgery. MethodsThis retrospective study enrolled children with drug-resistant focal epilepsy and hippocampal sclerosis with or without additional subtle T2-Fluid Attenuated Inversion Recovery (FLAR)/Proton Density (PD) signal changes in anterior temporal lobe who underwent anterior temporal lobectomy with amygdalohippocampectomy. Their clinical, EEG, neuropsychological, radiological and pathological data were reviewed and summarized. ResultsThirty-six eligible patients were identified. The mean age at seizure onset was 3.7 years; 25% had daily seizures at time of surgery. Isolated HS was noted in 22 (61.1%) cases and additional subtle signal changes in ipsilateral temporal lobe in 14 (38.9%) cases. Compared to the normative population, the group mean performance in intellectual functioning and most auditory and visual memory tasks were significantly lower than the normative sample. The mean age at surgery was 12.3 years; 22 patients (61.1%) had left hemispheric surgeries. ILAE class 1 outcomes was seen in 28 (77.8%) patients after a mean follow up duration of 2.3 years. Hippocampal sclerosis was noted pathologically in 32 (88.9%) cases; type 2 (54.5%) was predominant subtype where further classification was possible. Additional pathological abnormalities were seen in 11 cases (30.6%); these had had similar rates of seizure freedom as compared to children with isolated hippocampal sclerosis/gliosis (63.6% vs 84%, p=0.21). Significant reliable changes were observed across auditory and visual memory tasks at an individual level post surgery. ConclusionsFavourable seizure outcomes were seen in most children with isolated radiological hippocampal sclerosis. Patients with additional pathological abnormalities had similar rates of seizure freedom as compared to children with isolated hippocampal sclerosis/gliosis.

Tools used to measure the impact of comorbidities on surgical outcomes in children with complex chronic conditions: A scoping review.

To identify and describe assessment tools used to measure the impact of comorbidities on postoperative outcomes in children with complex chronic conditions (CCC). This was a scoping review using five electronic databases. The search was conducted in March 2022 by a medical librarian. There were no date or language restrictions. Included studies were full-text articles published in peer-reviewed journals that described a tool used to measure the impact of comorbidities in children with CCC to assess postoperative outcomes. A standardized data charting tool was used. A total of 2157 articles were retrieved. Five studies reporting on six comorbidity measures met inclusion criteria. All were cohort studies and were secondary analyses of data from an administrative database (n = 4) or a patient registry (n = 1). Sample sizes ranged from 645 to 25 747 participants. One paper described the assessment of reliability. Only one form of validity - predictive validity - was assessed in three papers for five measures. Findings from this scoping review revealed a paucity of comorbidity assessment tools validated for use with children with CCC; significant conceptual and measurement challenges exist in the current scientific literature.

Creating an autoencoder single summary metric to assess gait quality to compare surgical outcomes in children with cerebral palsy: The Shriners Gait Index (SGI)

Gait for individuals with movement disorders varies widely and the variability makes it difficult to assess outcomes of surgical and therapeutic interventions. Although specific joints can be assessed by fewer individual measures, gait depends on multiple parameters making an overall assessment metric difficult to determine. A holistic, summary measure can permit a standard comparison of progress throughout treatments and interventions, and permit more straightforward comparison across varied subjects. We propose a single summary metric (the Shriners Gait Index (SGI)) to represent the quality of gait using a deep learning autoencoder model, which helps to capture the nonlinear statistical relationships among a number of disparate gait metrics. We utilized gait data of 412 individuals under the age of 18 collected from the Motion Analysis Center (MAC) at the Shriners Children’s - Chicago. The gait data includes a total of 114 features: temporo-spatial parameters (7), lower extremity kinematics (64), and lower extremity kinetics (43) which were min–max normalized. The developed SGI score captured more than 89% variance of all 144 features using subject-wise cross-validation. Such summary metrics holistically quantify an individual’s gait which can then be used to assess the impact of therapeutic interventions. The machine learning approach utilized can be leveraged to create such metrics in a variety of contexts depending on the data available. We also utilized the SGI to compare overall changes to gait after surgery with the goal of improving mobility for individuals with gait disabilities such as Cerebral Palsy.

Analysis of Predictive Factors in Surgical Treatment of Intractable Epilepsy Caused by Focal Cortical Dysplasia in Children

Objective: This study aims to analyze key factors affecting the surgical outcome of children with intractable epilepsy caused by focal cortical dysplasia, providing more effective clinical guidance. Methods: We conducted a study from March 2019 to February 2021, selecting 80 children with intractable epilepsy caused by focal cortical dysplasia who underwent surgical treatment. Comprehensive inclusion criteria were met. We collected general information and treatment outcomes before and after surgery, with a two-year postoperative follow-up. Patients were categorized into good and poor outcome groups based on outcomes. Various factors including pathological types, age of onset, seizure frequency, and extent of resection were selected as variables. Logistic regression analysis investigated predictive factors. Results: Engel class I included 53 cases, class II had 16 cases, class III had 9 cases, and class IV had 2 cases. Thus, 53 cases were in the good outcome group, and 27 in the poor outcome group. General data showed no significant differences between the groups (P > 0.05). Single-factor analysis revealed statistically significant risk factors: FCD classification, MRI results, age of onset, seizure frequency, and extent of resection (P < 0.05). Logistic multifactor analysis indicated seizure frequency. acute postoperative seizures (APSO) and extent of resection as independent influencing factors (P < 0.05). Conclusion: Seizure frequency, extent of resection, and APSO are key independent factors for surgical outcome in children with intractable epilepsy caused by focal cortical dysplasia. Clinicians should consider these factors when planning treatment to improve success rates and outcome, enhancing quality of life for affected children.

Comparison of Short-Term Outcomes Following Surgical Intervention of Salivary Gland Malignancies in Adult and Pediatric Patients: A National Database Analysis

Background: Salivary gland malignancy (SGM) is a rare surgical pathology in the pediatric population, with currently ambiguous surgical management guidelines for the pediatric population. Therefore, we aim to use a national database to provide demographical and episode-of-care comparisons between the adult and pediatric population suffering from SGMs, with the interest of discovering baseline characteristic differences and outcomes, in addition to assessing the overall level of reporting at a national scale. Methods: The 2012 to 2019 American College of Surgeons’ National Surgical Quality Improvement Program Adult and Pediatric (ACS NSQIP, NSQIP-P) databases were queried to identify diagnoses of salivary gland malignancies based on postoperative ICD-10 codes. Age was stratified into adult (age ≥ 22 years) or pediatric (age &lt; 22 years). Each age-based cohort were further stratified based on cancer site. Demographics, comorbidities, and complications were compared between adults and children. Results: Overall, 1967 adult and 67 pediatric cases were included. Parotid gland malignancy comprised the majority of both adult and pediatric cases. Within cases of parotid gland malignancies, there were proportionally more adult compared to pediatric males. A lower comorbidity burden was also noted across pediatric cases. Operative time was slightly lower for pediatric cases compared to adult, with roughly 1 day less of total hospital stay. Complication rates were similar between adult and pediatric cases without statistically significant difference. Conclusions: Documentation of surgical outcomes in children with SGMs is severely lacking and continued reporting is imperative in order to improve outcomes of both oncologic and necessary reconstructive surgery. Optimal management of pediatric SGM demands use of a longitudinal multidisciplinary approach by surgeons cross-trained in head and neck surgery and plastic surgery. This is a burgeoning field with a need for studies aimed at developing guidelines specific for children.

Comparative analysis of surgical outcomes in children with type 3 and type 4 lateral physeal condylar humerus fractures in China: Closed Reduction-PerCutaneous Pinning (CRPP) vs. Open Reduction-Internal Fixation (ORIF)

BackgroundLateral physeal condylar humerus fractures in pediatric patients aged 1–13 rank as the second most common elbow injury, occurring with a frequency ranging from 5% to 16.8%. There exists an ongoing debate regarding the surgical management of these fractures. This study aims to evaluate the efficacy of Open Reduction and Internal Fixation (ORIF) and Closed Reduction and Percutaneous Pinning (CRPP) as suitable surgical treatments for displaced unstable fractures of the lateral condyle physeal humerus in children. The comparison encompasses the results of ORIF and CRPP, alongside clinical and radiographic outcomes and complication rates. MethodA retrospective review was conducted at the Department of Orthopedic Surgery in the research hospital. A cohort of 27 patients treated between 2016 and 2023 were analyzed, 19 patients meeting inclusion criteria. The fracture pattern and degree of displacement were assessed, with specialized radiologists, doctors, and surgeons in agreement. Among the patients, 11 underwent CRPP 7 type 3and 4 type 2, while 16 received ORIF 12 type 4 and 4 type 5. Data collection included fracture type, surgical method, operation time, pre and post-operative displacement, casting period, bone union condition, follow-up records, range of motion, complications, delayed union, lateral spurring, and pin removal records. ResultsFor CRPP, the mean time for pin removal was 5.42 weeks, with excellent bone union and an average operation time of 34.57 min. Criteria of Hardacre showed 28.57% of cases as good and 71.42% as excellent. Similarly, ORIF demonstrated a mean operation time of 42.5 min, with the fracture healing within 5.33 weeks and the pin being removed after 15 days on average. Criteria of Hardacre indicated 25% of cases as good and 75% as excellent. Both groups showed satisfactory outcomes, with no complications such as osteomyelitis, nonunion, malunion, delayed union, myositis ossificans, physeal growth arrest, tardy ulnar nerve palsy, cubitus valgus, or varus, and no cases requiring re-surgery. ConclusionBoth CRPP and ORIF are effective surgical methods for treating lateral physeal condylar humeral fractures (types 3 and 4 according to the Song classification) in children, demonstrating satisfactory outcomes. Notably, regardless of displacement (2 mm and >2 mm), both methods yield similar results, albeit with CRPP offering the advantage of avoiding incisions. Overall, both procedures are safe, with favorable bone healing outcomes.

Thyroid diseases in children and adolescents requiring surgical treatment-indications, techniques, results, and complications based on 10 years of the single center's own experience.

Although thyroid abnormalities are observed less frequently in children than in adults, the increased incidence of thyroid cancer makes it mandatory for all pediatric surgeons to be knowledgeable about the disorders of this gland. Thyroid abnormalities can be associated with hyperthyroidism or hypothyroidism and euthyroidism and/or symmetric or asymmetric enlargement of the gland. The present study was undertaken to retrospectively analyze the indications, surgical techniques used, results obtained, and complications found in the surgical treatment of thyroid diseases in children and adolescents in a surgical center for the macro-region of western Poland. The data of 148 patients undergoing total or partial thyroidectomy between 2013 and 2022 were analyzed from the medical records of the Department of Pediatric Surgery, Traumatology, and Urology of the Medical University of Poznan, Poland. A total of 95 children underwent subtotal thyroidectomy and 64 underwent total thyroidectomy, of which the procedure was widened to include prophylactic removal of neck lymph nodes in 45 patients. There were 113 girls (76%) in the analyzed group, and the average age of the patients at the time of surgical treatment was 15 years. The average time from the diagnosis of thyroid disease to surgery was 4 months, ranging from 2 weeks to 3 years. Of the 64 patients undergoing total thyroid resection, 35 (54.69%) were diagnosed with thyroid cancer. Collaboration within a multidisciplinary team ensures optimal surgical outcomes in children and adolescents with thyroid disease. With extreme caution, thyroid removal is a safe procedure with few complications, but the experience of the surgeon performing thyroid surgery in children remains crucial. Despite the absence of such a diagnosis in the first fine-needle aspiration biopsy, the high percentage of thyroid carcinomas in the analyzed group may be because the initial biopsy was performed in a less experienced center, also in terms of histopathological laboratory. Hence, we point out the necessity of performing a repeat fine-needle aspiration biopsy (according to the Bethesda classification) in a more experienced center before the final decision of thyroidectomy.

Posterior Annulus Elevation Technique in Reducing Residual Regurgitation During Mitral Valve Repair in Children: A Randomized Controlled Trial.

Background: The current technique used in severe mitral regurgitation in children can occasionally lead to residual regurgitation. To address this issue, the posterior annulus elevation technique was developed to enhance coaptation and reduce residual lesions. This study aims to evaluate the effectiveness of this technique in reducing residual regurgitation during mitral valve repair in children. Methods: A total of 64 patients aged <18 years old undergoing mitral valve repair were randomized into two groups: the intervention (with posterior annulus elevation) group and the control group, which underwent conventional repair techniques. Various parameters, including coaptation area, residual mitral regurgitation, clinical outcomes, metabolic, and hemolytic markers, were measured on days 0, 5, 2 weeks, and 3 months after surgery. Results: The intervention group (n = 32) showed a significant reduction in residual mitral regurgitation compared with the control group (n = 32) on each evaluation. At three months after surgery, we found that the posterior annulus elevation technique could be a protective factor that reduces the chance of residual regurgitation compared with the control group (RR = 0.31; confidence interval: 0.18-0.54; P ≤ .001). Coaptation length and index were also found to be significantly higher in the intervention group (P ≤ .001). Clinical outcomes, metabolic markers, and hemolysis marker did not show any significant differences between the two groups. Conclusions: The posterior annulus elevation technique demonstrated effectiveness in reducing residual mitral regurgitation and improving coaptation area in pediatric mitral valve repair. This technique showed better short-term surgical outcomes in children with mitral regurgitation compared with the conventional technique.

Long-term seizure and developmental outcomes of epilepsy surgery in children under 3 years old: A single-center study of 113 patients.

To investigate the clinical characteristics, surgical strategy, developmental and seizure outcomes, and predictors of surgical outcome in children with drug-resistant epilepsy (DRE) under 3 years old. One hundred thirteen consecutive children younger than 3 years of age with DRE underwent curative surgical treatment after multidisciplinary preoperative evaluation using the strategy developed in the pediatric epilepsy center of Peking University First Hospital (PKFHPEC) between 2014 and 2018. These patients were selected for retrospective study. The relevant clinical data were collected and analyzed. The surgical prognoses were classified using the Engel classification, and the developmental assessment results were collected. Statistical analysis of the clinical data was performed to analyze the predictors of seizure outcomes and their correlation with developmental outcomes. All the patients were followed up for more than 3 years, and 98 (86.7%) patients had no seizure recurrence. One year after surgery, the seizure-free rate was 86.7%, which was as high as that at the last follow-up. Cortical dysplasia was the most frequent etiology of DRE in this cohort, accounting for 77.0%. According to the Engel classification, acute postoperative seizure (APOS; p < 0.001) was a predictor of seizure recurrence. No deaths occurred. No unpredicted long-term severe complications occurred except for one ventricular peritoneal shunt. The patients' neurodevelopmental statuses were improved after successful surgery, while the scores of the pre- and postoperative developmental assessments were closely correlated. For children who are younger than 3 years old and have DRE and structural abnormalities, early curative treatment can lead to long-term good seizure outcomes and a low complication rate. The development of appropriate strategies for both presurgical evaluation and resection is crucial for the success of surgery.

Neighborhood Childhood Opportunity, Race/Ethnicity, and Surgical Outcomes in Children With Congenital Heart Disease

BackgroundRacial and ethnic disparities in outcomes for children with congenital heart disease (CHD) coexist with disparities in educational, environmental, and economic opportunity. ObjectivesWe sought to determine the associations between childhood opportunity, race/ethnicity, and pediatric CHD surgery outcomes. MethodsPediatric Health Information System encounters aged <18 years from 2016 to 2022 with International Classification of Diseases-10th edition codes for CHD and cardiac surgery were linked to ZIP code-level Childhood Opportunity Index (COI), a score of neighborhood educational, environmental, and socioeconomic conditions. The associations of race/ethnicity and COI with in-hospital surgical death were modeled with generalized estimating equations and formal mediation analysis. Neonatal survival after discharge was modeled by Cox proportional hazards. ResultsOf 54,666 encounters at 47 centers, non-Hispanic Black (Black) (OR: 1.20; P = 0.01), Asian (OR: 1.75; P < 0.001), and Other (OR: 1.50; P < 0.001) groups had increased adjusted mortality vs non-Hispanic Whites. The lowest COI quintile had increased in-hospital mortality in unadjusted and partially adjusted models (OR: 1.29; P = 0.004), but not fully adjusted models (OR: 1.14; P = 0.13). COI partially mediated the effect of race/ethnicity on in-hospital mortality between 2.6% (P = 0.64) and 16.8% (P = 0.029), depending on model specification. In neonatal multivariable survival analysis (n = 13,987; median follow-up: 0.70 years), the lowest COI quintile had poorer survival (HR: 1.21; P = 0.04). ConclusionsChildren in the lowest COI quintile are at risk for poor outcomes after CHD surgery. Disproportionally increased mortality in Black, Asian, and Other populations may be partially mediated by COI. Targeted investment in low COI neighborhoods may improve outcomes after hospital discharge. Identification of unmeasured factors to explain persistent risk attributed to race/ethnicity is an important area of future exploration.

Electromagnetic source imaging predicts surgical outcome in children with focal cortical dysplasia

ObjectiveTo evaluate the diagnostic accuracy of electromagnetic source imaging (EMSI) in localizing spikes and predict surgical outcome in children with drug resistant epilepsy (DRE) due to focal cortical dysplasia (FCD). MethodsWe retrospectively analyzed magnetoencephalography (MEG) and high-density (HD-EEG) data from 23 children with FCD-associated DRE who underwent intracranial EEG and surgery. We localized spikes using equivalent current dipole (ECD) fitting, dipole clustering, and dynamical statistical parametric mapping (dSPM) on EMSI, electric source imaging (ESI), and magnetic source imaging (MSI). We calculated the distance from the seizure onset zone (DSOZ) and resection (DRES). We estimated receiver operating characteristic (ROC) curves with Youden’s index (J) to predict outcome. ResultsEMSI presented shorter DSOZ (15.18 ± 9.06 mm) and DRES (8.56 ± 6.24 mm) compared to ESI (DSOZ: 25.04 ± 16.20 mm, p < 0.009; DRES: 18.88 ± 17.30 mm, p < 0.03) and MSI (DSOZ: 23.37 ± 8.98 mm, p < 0.03; DRES: 15.51 ± 10.11 mm, p < 0.02) for clustering in patients with good outcome. Clustering showed shorter DSOZ and DRES compared to ECD fitting and dSPM (p < 0.05). EMSI had higher performance as outcome predictor (J = 70.63%) compared to ESI (J = 41.27%) and MSI (J = 33.33%) for clustering. ConclusionsEMSI provides superior localization and improved predictive performance than individual modalities. SignificanceEMSI can help the surgical planning and facilitate the localization of epileptogenic foci.

Functional connectivity discriminates epileptogenic states and predicts surgical outcome in children with drug resistant epilepsy

Normal brain functioning emerges from a complex interplay among regions forming networks. In epilepsy, these networks are disrupted causing seizures. Highly connected nodes in these networks are epilepsy surgery targets. Here, we assess whether functional connectivity (FC) using intracranial electroencephalography can quantify brain regions epileptogenicity and predict surgical outcome in children with drug resistant epilepsy (DRE). We computed FC between electrodes on different states (i.e. interictal without spikes, interictal with spikes, pre-ictal, ictal, and post-ictal) and frequency bands. We then estimated the electrodes’ nodal strength. We compared nodal strength between states, inside and outside resection for good- (n = 22, Engel I) and poor-outcome (n = 9, Engel II–IV) patients, respectively, and tested their utility to predict the epileptogenic zone and outcome. We observed a hierarchical epileptogenic organization among states for nodal strength: lower FC during interictal and pre-ictal states followed by higher FC during ictal and post-ictal states (p < 0.05). We further observed higher FC inside resection (p < 0.05) for good-outcome patients on different states and bands, and no differences for poor-outcome patients. Resection of nodes with high FC was predictive of outcome (positive and negative predictive values: 47–100%). Our findings suggest that FC can discriminate epileptogenic states and predict outcome in patients with DRE.

Clinical characteristics and surgical outcomes in children with mild malformation of cortical development and oligodendroglial hyperplasia in epilepsy.

Mild malformation of cortical development with oligodendroglial hyperplasia in epilepsy (MOGHE) is a new and rare histopathological entity of cortical developmental malformations. The clinical characteristics of MOGHE remain challenging. Children with histologically confirmed MOGHE were retrospectively studied. The clinical findings, electroclinical and imaging features, and postoperative outcomes were analyzed, and previously published studies were reviewed up to June 2022. Thirty-seven children were included in our cohort. Clinical characteristics included early onset in infancy (94.6% before 3 years), multiple seizure types, and moderate or severe delay. Epileptic spasm is the most common seizure type and initial manifestation. The lesions were mainly multilobar (59.5% multiple lobes and 8.1% hemispheres), and predominance in the frontal lobe was observed. The interictal EEG pattern was circumscribed or widespread. The prominent MRI characteristics were cortical thickening, cortical/subcortical hyperintense T2/FLAIR signal, and blurring at the GM and WM transition. Among the 21 children followed up for more than 1 year after surgery, 76.2% were seizure-free. Preoperative interictal circumscribed discharges and larger resections were significantly associated with a good postoperative outcome. The clinical features of 113 patients in the reviewed studies were similar to those we reported, but the lesions were mainly unilobar (73.5%) and Engel I was achieved in only 54.2% after surgery. Distinct clinical characteristics in MOGHE, especially age at onset, epileptic spasm, and age-related MRI characteristics, can help in early diagnosis. Preoperative interictal discharge and surgical strategy may be predictors of postoperative outcomes.

The Effects of Orthoptic Therapy on the Surgical Outcome in Children with Intermittent Exotropia: Randomised Controlled Clinical Trial

To assess the clinical effectiveness of orthoptic therapy in the postoperative stabilisation and rehabilitation of binocular function in children with intermittent exotropia (IXT) after surgery. This was a prospective, parallel, randomised controlled trial. A total of 136 IXT patients (aged from 7 to 17 years) who had been successfully corrected at 1 month after surgery were enrolled in this study, and 117 patients (58 controls) completed the 12-month follow-up visit. The primary outcome was established as the proportion of patients with suboptimal surgical outcomes, which were defined as: (1) exodeviation ≥10 prism diopters (PD) at distance or near using the simultaneous prism and cover test (SPCT), or (2) constant esotropia ≥6 PD at distance or near using SPCT, or (3) loss of 2 or more octaves of stereopsis from baseline. The secondary outcomes were the exodeviation at distance and near using the prism and alternate cover test (PACT), stereopsis, fusional exotropia control and convergence amplitude. The cumulative probability of suboptimal surgical outcome by 12 months was 20.5% (14/68) in the orthoptic therapy group and 42.6% (29/68) in the control group. There was a significant difference between these two groups (χ2 = 7.402, p = 0.007). Improvements in stereopsis, fusional exotropia control and fusional convergence amplitude were found in the orthoptic therapy group. A smaller exodrift was found in the orthoptic therapy group at near fixation (t = 2.26, p = 0.025). Early postoperative orthoptic therapy can effectively improve the surgical outcome as well as stereopsis and fusional amplitude.

Automated seizure onset zone locator from resting-state functional MRI in drug-resistant epilepsy.

Accurate localization of a seizure onset zone (SOZ) from independent components (IC) of resting-state functional magnetic resonance imaging (rs-fMRI) improves surgical outcomes in children with drug-resistant epilepsy (DRE). Automated IC sorting has limited success in identifying SOZ localizing ICs in adult normal rs-fMRI or uncategorized epilepsy. Children face unique challenges due to the developing brain and its associated surgical risks. This study proposes a novel SOZ localization algorithm (EPIK) for children with DRE. EPIK is developed in a phased approach, where fMRI noise-related biomarkers are used through high-fidelity image processing techniques to eliminate noise ICs. Then, the SOZ markers are used through a maximum likelihood-based classifier to determine SOZ localizing ICs. The performance of EPIK was evaluated on a unique pediatric DRE dataset (n = 52). A total of 24 children underwent surgical resection or ablation of an rs-fMRI identified SOZ, concurrently evaluated with an EEG and anatomical MRI. Two state-of-art techniques were used for comparison: (a) least squares support-vector machine and (b) convolutional neural networks. The performance was benchmarked against expert IC sorting and Engel outcomes for surgical SOZ resection or ablation. The analysis was stratified across age and sex. EPIK outperformed state-of-art techniques for SOZ localizing IC identification with a mean accuracy of 84.7% (4% higher), a precision of 74.1% (22% higher), a specificity of 81.9% (3.2% higher), and a sensitivity of 88.6% (16.5% higher). EPIK showed consistent performance across age and sex with the best performance in those < 5 years of age. It helped achieve a ~5-fold reduction in the number of ICs to be potentially analyzed during pre-surgical screening. Automated SOZ localization from rs-fMRI, validated against surgical outcomes, indicates the potential for clinical feasibility. It eliminates the need for expert sorting, outperforms prior automated methods, and is consistent across age and sex.

Income Disparities in Nationwide Outcomes of Malrotation with Midgut Volvulus

BackgroundMalrotation with midgut volvulus is a surgical emergency commonly encountered in pediatric surgical practice. Outcomes are excellent with timely diagnosis and treatment, but the development of bowel ischemia is associated with many negative consequences. MethodsThe Nationwide Readmissions Database was used to identify patients 0–18 years (excluding newborns) with malrotation and midgut volvulus from 2010 to 2014. Demographics, procedures, and outcomes were compared by income group (highest quartile vs. lowest quartile) using standard statistical tests. Results were weighted for national estimates. ResultsEmergency surgery for midgut volvulus was performed in 572 patients. The majority (86%) underwent Ladd's procedure, while 14% required bowel resection and/or ostomy. Patients in the lowest income quartile were more likely to require bowel resection (18% vs. 8%, p = 0.03) or ostomy (9% vs. 2%, p = 0.015) compared to those in the highest income quartile. Low-income patients were more likely to experience prolonged hospital stay (8 [5-13] days vs. 6 [4-8] days, p<0.001) and experience complications including infections (19% vs. 5%, p = 0.002), endotracheal intubation (18% vs. 4%, p<0.001), and blood transfusions (13% vs. 3%, p = 0.003). ConclusionIncome disparity represents a major factor in surgical outcomes in children with midgut volvulus. A broad spectrum of clinical outcomes following surgery for midgut volvulus exists. Patients from lower-income communities are at significantly higher risk for numerous complications, negative outcomes, and higher resource utilization. These findings support additional investigations of practices to mitigate risk for low-income patients. Level of evidenceLevel III: Retrospective comparative study

Cor triatriatum sinister: Long-term surgical outcomes in children and a proposal for a new classification.

Cor Triatriatum Sinister (CTS) is a rare congenital anomaly with an estimated incidence of 0.4%, resulting from abnormal left atrial septation. It may present in isolation or in association with other heart defects. High percentage of patients require surgery with low mortality and recurrence rates. CTS has been classified in the past however we aim to describe a case series with more comprehensive and inclusive classification. This was a single-center retrospective cohort study of 16 children with the diagnosis of CTS between 2000 and 2020. Medical records were reviewed for clinical presentations, hospital, and postoperative courses. Sixteen patients (63% female), with a median age at diagnosis of 4.3 months, five (31%) were neonates. Six (38%) had isolated CTS, two (13%) with functional single ventricle (SV), and the remaining eight patients (50%) had other associated heart defects (septal defects in three, coarctation of the aorta in another three, and anomalous pulmonary venous connections in three). Eight patients (50%) presented with obstructed CTS. Twelve patients (75%) underwent surgical intervention. Mortality occurred in three patients (19%) with two surgical (one with total anomalous pulmonary venous connection and another with SV) and one nonsurgical (septal defect with Fanconi anemia). The surgical median follow up was 4.7 years. Recurrence of the membrane occurred in two patients (17%). This study showed good long-term outcomes for patients with isolated and complex CTS. Complete and proper classification of CTS ensures appropriate diagnosis, surgical planning, and better family counseling which may correlate with outcomes.

Association Between Race, Gender, and Pediatric Postoperative Outcomes: An Updated Retrospective Review

IntroductionThere has not been a recent evaluation of the association between racial and gender and surgical outcomes in children. We aimed to evaluate improvements in race- and gender-related pediatric postoperative outcomes since a report utilizing the Kids’ Inpatient Database data from 2003 to 2006. MethodsUsing Kids’ Inpatient Database (2009, 2012, 2016), we identified 245,976 pediatric patients who underwent appendectomy for acute appendicitis (93.6%), pyloromyotomy for pyloric stenosis (2.7%), empyema decortication (1.6%), congenital diaphragmatic hernia repair (0.7%), small bowel resection for intussusception (0.5%), or colonic resection for Hirschsprung disease (0.2%). The primary outcome was the development of postoperative complications. Multivariable logistic regression was used to evaluate risk-adjusted associations among race, gender, income, and postoperative complications. ResultsMost patients were male (61.5%) and 45.7% were White. Postoperative complications were significantly associated with male gender (P < 0.0001) and race (P < 0.0001). After adjustment, Black patients were more likely to experience any complication than White patients (adjusted odds ratio 1.3, confidence interval 1.2-1.4), and males were more likely than females (adjusted odds ratio 1.3, confidence interval 1.2-1.4). ConclusionsNo clear progress has been made in eliminating race- or gender-based disparities in pediatric postoperative outcomes. New strategies are needed to better understand and address these disparities.

Surgical outcomes in children with Trisomy 13: An ACS NSQIP – Pediatric review

BackgroundTrisomy 13 is a rare genetic condition with a characteristic set of severe congenital abnormalities. Traditionally, the standard of care was to provide palliative care only. However, there has been a recent shift towards life-prolonging care, including surgery. This study seeks to describe surgical outcomes in patients with trisomy 13 and compare them to comorbidity-matched controls. MethodsUsing the ACS NSQIP Pediatric 2012–2019 Participant Use Data Files, patients with trisomy 13 were identified and described. A nearest-neighbor 10:1 propensity score match was performed using demographics, comorbidities, and procedural details. This yielded 254 patients with trisomy 13 and 2,422 controls. Risk ratios for morbidity and mortality by trisomy 13 status were determined using modified Poisson regression. The primary outcomes were thirty-day mortality and the occurrence of any morbidity. ResultsThe median age of patients with trisomy 13 was 16 months (IQR 87 months). 126 were male (49.6%) and 128 were female (50.4%). There were no differences in overall morbidity compared to controls (31.8% vs. 29.7%, RR 1.06, 95%CI 0.87–1.28, p = 0.554), but patients with trisomy 13 had markedly higher mortality (7.9% vs. 1.8%, RR 4.43, 95%CI 2.28–8.61, p<0.001). ConclusionsWe conclude that patients with trisomy 13 undergoing surgery have frequent morbidity and an elevated although not prohibitive risk of death. Compared to patients with similar comorbidities, they have similar rates of morbidity but a markedly higher risk of mortality. Parents of children with trisomy 13 require thorough counseling on these risks before deciding on surgery.
