RESUMEN
Craniosynostosis, a medical condition characterized by premature fusion of one or multiple cranial sutures, has historically been treated through surgical correction. Computerized Surgical Planning (CSP) and three-dimensional (3D) modeling have gained significant popularity across craniofacial surgery. Through a collaborative effort between surgeons and engineers, it is now possible to virtually execute a surgical plan based on preoperative imaging using computed tomography scans. The CSP workflow involves several elements including virtual 3D modeling, CSP computer-aided surgical guide design, manufacturing of guides and templates, and intraoperative implementation. Through the gradual optimization of this workflow, it has been possible to achieve significant progress in the surgical process including improvements in the preoperative planning of complex craniosynostosis cases and reduction of intraoperative time. Furthermore, CSP and 3D modeling have had a positive impact on surgical simulation and residency training, along with patient education and counseling. This article summarizes the CSP workflow in the treatment of craniosynostosis and the implications of this treatment modality on medical trainee education and patient management.
RESUMEN
OBJECTIVE: While previous literature has investigated the psychosocial impact and aesthetic satisfaction associated with post-operative scarring for certain pediatric craniofacial conditions, the impact of the scar burden resulting from craniosynostosis surgery has not been adequately studied. PARTICIPANTS: SCAR-Q was shared with patients ages 8 and older. Thirty-two complete patient responses were recorded. INTERVENTIONS: SCAR-Q is a PROM that consists of three independent scales - appearance, symptoms, and psychosocial impact - associated with a scar. MAIN OUTCOME MEASURES: Mann-Whitney U, linear regression, and Pearson correlation tests were used to evaluate associations between the scales, in addition to patient characteristics such as sex and suture involvement. RESULTS: Mean ages at time of surgery and survey completion were 9.65 ± 10.10 months and 12.10 ± 3.92 years, respectively. Mean scale scores were 81.5 ± 17.9 for appearance, 86.8 ± 12.4 for symptoms, and 79.3 ± 25.7 for psychosocial impact. Higher patient dissatisfaction with scar appearance correlated with more scar-related symptoms (r = 0.389; p = 0.028) and a greater psychosocial impact (r = 0.725; p < 0.001). SCAR-Q scales did not significantly correlate with age at surgery, age at survey completion, type of synostosis, or type of surgery; however, female patients reported lower mean appearance (65.4 vs. 86.0; p = 0.012) and psychosocial impact (57.3 vs. 85.5; p = 0.010) scores when compared to their male counterparts. CONCLUSIONS: It is vital that surgeons discuss patients' aesthetic satisfaction following craniosynostosis surgery in order to appropriately address and limit deleterious, long-term physical and psychosocial outcomes.
RESUMEN
PURPOSE: The purpose of the study was to determine if antegrade continence enema (ACE) alone is an effective treatment for patients with severe functional constipation and segmental colonic dysmotility. METHODS: A retrospective study of patients with functional constipation and segmental colonic dysmotility who underwent ACE as their initial means of management. Data was collected from six participating sites in the Pediatric Colorectal and Pelvic Learning Consortium. Patients who had a colonic resection at the same time as an ACE or previously were excluded from analysis. Only patients who were 21 years old or younger and had at least 1-year follow-up after ACE were included. All patients had segmental colonic dysmotility documented by colonic manometry. Patient characteristics including preoperative colonic and anorectal manometry were summarized, and associations with colonic resection following ACE were evaluated using Fisher's exact test and Wilcoxon rank-sum test. p-Values of less than 0.05 were considered significant. Statistical analyses and summaries were performed using SAS version 9.4 (SAS Institute Inc., Cary, North Carolina, United States). RESULTS: A total of 104 patients from 6 institutions were included in the study with an even gender distribution (males n = 50, 48.1%) and a median age of 9.6 years (interquartile range 7.4, 12.8). At 1-year follow-up, 96 patients (92%) were successfully managed with ACE alone and 8 patients (7%) underwent subsequent colonic resection for persistent symptoms. Behavioral disorder, type of bowel management, and the need for botulinum toxin administered to the anal sphincters was not associated with the need for subsequent colonic resection. On anorectal manometry, lack of pelvic floor dyssynergia was significantly associated with the need for subsequent colonic resection; 3/8, 37.5% without pelvic dyssynergia versus 1/8, 12.5% (p = 0.023) with pelvic dyssynergia underwent subsequent colonic resection. CONCLUSION: In patients with severe functional constipation and documented segmental colonic dysmotility, ACE alone is an effective treatment modality at 1-year follow-up. Patients without pelvic floor dyssynergia on anorectal manometry are more likely to receive colonic resection after ACE. The vast majority of such patients can avoid a colonic resection.
RESUMEN
BACKGROUND: Reconstruction of facial melanoma defects can be challenging. Large defects of the midface, cheek, and nasolabial fold are often reconstructed using a cervicofacial flap which requires significant flap elevation and undermining. Surgeons are often hesitant to commit to such a large reconstruction without definitive pathologic evidence of negative margins. However, local perforator flaps may be used as an alternative to large flaps with less dissection and donor site morbidity and may also allow for more facile re-advancement in the event of a positive margin on final pathology. The goal of this study is to evaluate a perforator flap based on the facial artery to determine if it is a safe and cosmetically favorable option to immediately repair oncologic-related defects on the cheek and midface. METHODS: A retrospective review of all melanoma cases performed by the senior author between January 2016 and December 2021 was conducted. Patients who underwent reconstruction using a facial artery perforator flap were included. RESULTS: Sixteen patients were included in our cohort. The average age was 67.3 years and 53% (n=8) were female. Fourteen patients had the primary defect located on the cheek, 1 from the nasolabial fold, and 1 from the distal nasal sidewall. All patients received immediate reconstruction. Excisional margins ranged from 0.5 to 2 cm. Two patients had positive margins following pathology results with one undergoing treatment with imiquimod and the other opting for re-excision. No complications involving the defect or donor site were reported after an average follow-up time of 113.8 days. CONCLUSION: The facial artery perforator flap is a safe and cosmetically favorable option to immediately repair oncologic-related defects on the cheek and midface.

PURPOSE: Fecal incontinence is a problem for many patients born with an anorectal malformation (ARM) that can impact quality of life. It is unknown if racial, ethnic, and socioeconomic disparities relate to fecal continence in these children. We sought to examine outcomes and potential disparities in care. METHODS: We performed a multicenter retrospective study of children > 3y with ARM evaluated at sites participating in the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC). The primary outcome was fecal continence. We evaluated for associations between fecal continence and race, sex, age, and insurance status. RESULTS: 509 patients with ARM from 11 institutions were included. Overall, 24% reported complete fecal continence, and fecal continence was associated with older age (p < .001). For school-aged children, 27% reported complete continence, while 53% reported none. On univariate analysis, patients with combined private and public insurance showed lower rates of continence when compared to those with private insurance (23 vs. 12%; p = 0.02). Age was associated with continence on univariate and multivariable analyses. CONCLUSION: Rates of complete fecal continence in this population are low. Differences based on payor status may exist. There were no observed disparities related to sex and race. Further investigation is warranted to improve care for this patient population. LEVEL OF EVIDENCE: III. TYPE OF STUDY: Multi-institutional retrospective comparative study.

OBJECTIVE: Neuromyelitis optica spectrum disorders (NMOSD) represent rare autoimmune diseases of the central nervous system largely targeting optic nerve(s) and spinal cord. The present analysis used real-world data to identify clinical and epidemiological correlates of treatment change in patients with NMOSD. METHODS: CIRCLES is a longitudinal, observational study of NMOSD conducted at 15 centers across North America. Patients with ≥ 60 days of follow-up and receiving on-study maintenance treatment were evaluated. The mean annual relapse rate (ARR) was estimated using negative binomial models; the likelihood of treatment change was estimated using Cox proportional hazards models. Relapses were included as time-varying covariates to estimate the relationship to treatment change. RESULTS: Of 542 patients included, 171 (31.5%) experienced ≥ 1 relapse on the study and 133 patients (24.5%) had ≥ 1 change in the treatment regimen. Two categories of variables significantly correlated with the likelihood of treatment change: (1) relapse: any on-study relapse (hazard ratio [HR] = 2.91; p < 0.001), relapse phenotypes (HR range = 2.15-5.49; p < 0.001), and pre-study ARR > 0.75 (HR 2.28; p < 0.001); 2) disease phenotype: brain syndrome only vs transverse myelitis involvement at onset (HR 2.44; p = 0.008), disease duration < 1 vs > 5 years (HR 1.66; p = 0.028), or autoimmune comorbidity (HR 1.55; p = 0.015). A subset of these factors significantly correlated with shorter time to first rituximab discontinuation. CONCLUSIONS: In CIRCLES, relapse patterns and disease phenotype significantly correlated with changes in the maintenance treatment regimen. Such findings may facilitate the identification of patients with NMOSD who are likely to benefit from treatment change to reduce relapse risk or disease burden and enhance the quality of life.

PURPOSE: Fecal continence is a concern for many patients with idiopathic constipation and can significantly impact quality of life. It is unknown whether racial, ethnic, and socioeconomic disparities are seen in fecal continence within the idiopathic constipation population. We aimed to evaluate fecal continence and associated demographic characteristics in children with idiopathic constipation referred for surgical evaluation. METHODS: A multicenter retrospective study of children with idiopathic constipation was performed at sites participating in the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC). All patients >3y of age with idiopathic constipation diagnosis were included. The primary outcome was fecal continence, categorized as complete (no accidents ever), daytime (no accidents during the day), partial (occasional incontinence day/night), and none (incontinent). We evaluated for associations between fecal continence and race, sex, age, insurance status, and other patient-level factors, employing Kruskal-Wallis and trend tests. RESULTS: 458 patients with idiopathic constipation from 12 sites were included. The median age of diagnosis was 4.1 years. Only 25% of patients referred for surgical evaluation were completely continent. Age at the visit was significantly associated with fecal continence level (p = 0.002). In addition, patients with public and mixed public and private insurance had lower levels of continence (p<0.001). Patients with developmental delay were also more likely to have lower continence levels (p = 0.009) while diagnoses such as anxiety, ADD/ADHD, autism, depression, obsessive-compulsive disorder were not associated. Approximately 30% of patients had an ACE operation (antegrade continence enema) at a median age of 9.2 years at operation. Black patients were significantly less likely to undergo ACE operation (p = 0.016) when compared to white patients. CONCLUSION: We observed data that suggest differences in fecal incontinence rates based on payor status. Further investigation is needed to characterize these potential areas of disparate care. LEVEL OF EVIDENCE: Level III.

INTRODUCTION: Children with severe constipation and a neurodiverse disorder (Autism and/or developmental delay) represent a challenging bowel management group. Treatment outcomes with laxative or enema therapy remain limited and are often complicated by patient/caregiver compliance. We hypothesized that children with neurodiverse disorders and severe constipation would benefit from a bowel management program (BMP) that includes early use of antegrade enemas. MATERIALS AND METHODS: Children requiring BMP in the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC) registry with diagnosis of constipation and/or constipation with pseudo-incontinence were reviewed. Those with Hirschsprung disease and/or Anorectal Malformation were excluded. BMP needs in patients with a neurodiverse diagnosis were compared to those without to evaluate differences in BMP's. RESULTS: 372 patients requiring a BMP were identified. 95 patients (58 autism spectrum, 54 developmental delay) were neurodiverse, and 277 patients were not. Neurodiverse patients had a higher prevalence of enema therapy 62.1% (59/95) vs. 54.9% (152/273) and use of antegrade enema therapy 33.7% (32/95) vs. 21.2% (58/273), p = 0.126. Neurodiverse patients were older 37.9% (36/95) > 12 years vs. 23.1% (63/273), p = 0.001 and 47.6% (10/21) were changed from laxative to enema therapy over time. 80% (8/10) of those changed from laxatives to enemas used antegrade therapy. 67.3% (35/52) of neurodiverse patients followed over time were on enema therapy at the most recent visit with 80% (28/35) requiring antegrade therapy. CONCLUSION: A large portion of patients with a neurodiverse disorder who fail laxative therapy use antegrade enemas to achieve effective bowel management. Early consideration of an antegrade conduit may simplify treatment in this group of children. LEVEL OF EVIDENCE: III.

BACKGROUND: Health-related quality of life (HRQOL) is an important outcome among children with Hirschsprung Disease (HD), but there are challenges in interpreting findings in previous studies owing to the choice of a comparator group and informant. We compared parent-proxy versus child self-report HRQOL in children with HD to children with functional constipation (FC) and examined predictors of HRQOL. METHODS: Data of 126 children (5-18 years, 60.3% male, HD: n = 52, FC: n = 74) were acquired from the Pediatric Colorectal and Pelvic Learning Consortium. Demographics, clinical variables, HRQOL (Pediatric Quality of Life Inventory parent-proxy; child self-report) and functional outcomes (Baylor Continence Scale, Cleveland Clinic Constipation Scoring System) were collected. RESULTS: Parent and child HRQOL was similar for both cohorts, with higher scores on physical functioning and lower scores on emotional and school functioning. For children with HD, demographics and clinical variables did not predict HRQOL in multivariable regression models. For children with FC, greater severity of constipation predicted lower HRQOL (parent-proxy: B = -2.14, p < 0.001; child: B = -1.75, p = 0.001). Parent-child agreement on HRQOL scores was poor to moderate in the HD group (intraclass correlations (ICC)=0.38-0.74), but moderate to excellent in the FC group (ICC=0.63-0.84). Furthermore, parents of children with FC and ≤10 years overestimated children's HRQOL (proportional OR 4.59 (1.63, 13.85); p = 0.004). CONCLUSION: Clinical symptoms and demographic factors did not predict HRQOL among children with HD, highlighting the need to examine other biopsychosocial factors to understand long term HRQOL. Low parent-child HRQOL agreement in children with HD demonstrates the importance of obtaining parent and child perspectives. LEVEL OF EVIDENCE: III. TYPE OF STUDY: Prognosis study.

PURPOSE: Botulinum toxin (BT) is used to treat pediatric patients with Hirschsprung disease (HD) with obstructive symptoms. We aimed to characterize use of BT in HD patients across pediatric colorectal surgery referral centers. METHODS: A multicenter retrospective study of BT use in children (0-18y) with HD was performed using the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC) between 2017 and 2021. Sites with <10 HD patients recorded were excluded. Patterns were evaluated using Fisher's exact, Wilcoxon rank-sum, Kruskal-Wallis, and Cochran-Armitage trend test. RESULTS: 494 patients at 8 centers were included. 118 (23.9%) received at least one BT injection. Among patients who required redo pullthrough procedures, 53.1% received BT compared to 22.7% of patients who only underwent one pullthrough (p<0.001). Age at pullthrough was also significantly associated (p = 0.021). A lower proportion of Hispanic patients received BT (9.6% vs. 26.3%;p = 0.006). Percentage of HD patients receiving BT varied significantly across sites (p<0.001). CONCLUSIONS: Use of BT in patients with HD varies widely with greater use in patients who underwent redo surgery and in those who underwent pullthrough at an older age. Hispanic patients received less BT. These findings highlight the need to develop consensus guidelines and for further study on timing of injections and potential disparities in care.

PURPOSE: While fecal incontinence is a primary concern for many children with anorectal malformations (ARM), urinary incontinence is also prevalent in this population. Racial, ethnic, and socioeconomic disparities in urinary continence have been observed in other conditions, but have not been previously evaluated in ARM. We aimed to evaluate urinary continence and associated demographic and socioeconomic characteristics in individuals with ARM. METHODS: We performed a multicenter retrospective study of ARM patients evaluated at sites participating in the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC). We included all patients with ARM 3 years and older. The primary outcome was urinary continence which was categorized as complete (no accidents), daytime (accidents at night), partial (rare or occasional accidents), and none (frequent accidents or no continence). We evaluated for associations between urinary continence and race, sex, age, insurance status, and adoption status, employing Kruskal-Wallis and trend tests. Secondary outcomes included bladder management strategies such as clean intermittent catheterization and continence surgery. P-value < 0.05 was considered significant. RESULTS: A total of 525 patients with ARM were included. Overall, 48% reported complete urinary continence, and continence was associated with greater age. For school-aged children (age ≥ 5 years), 58% reported complete continence, while 30% reported none. Public insurance and adoption status were associated with decreased likelihood of incontinence. CONCLUSIONS: We observed a novel finding of disparities in urinary continence for children with ARM related to insurance and adoption status. Further investigation regarding the etiologies of these inequities is needed in order to affect clinical outcomes.

BACKGROUND/PURPOSE: the timing of endorectal pull-through for Hirschsprung disease (HD) is controversial. Neonatal primary endorectal pull-through theoretically prevents preoperative enterocolitis. Delayed primary endorectal pull-through offers the surgeon the benefit of more robust perineal anatomy and allows primary caregivers the time to emotionally process the diagnosis and to gain experience with rectal irrigations. We hypothesized that delayed primary endorectal pull-through would be associated with equivalent perioperative morbidity compared to the neonatal repair and would lead to improved long-term functional outcomes. METHODS: we analyzed all patients in the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC) registry who had a primary endorectal pull-through for HD and at least three-and-one-half years of follow up in a specialty colorectal clinic. We evaluated patient demographics, operative outcomes, perioperative episodes of enterocolitis, and long-term functional outcomes for the neonatal (<31 days) and delayed (≥31 days) pull-through cohorts. RESULTS: eighty-two patients were identified of whom 49 were operated upon in the neonatal period and 33 in a delayed fashion. The median age at operation was 11 days [IQR 7 - 19 days] for the neonatal cohort and 98 days [IQR 61 - 188 days] for the delayed cohort. Thirty-four (69.4%) of the neonatal and 22 (66.7%) of the delayed cohort patients had rectosigmoid transition zones. Four of 49 patients (8.1%) in the neonatal cohort were diagnosed with enterocolitis preoperatively compared to two of 33 (6.0%) in the delayed cohort (p = 0.89). Eighteen of 49 patients (36.7%) in the neonatal cohort and 16 of 33 (48.5%) in the delayed cohort had at least one postoperative episode of enterocolitis (p = 0.38). Fifteen of 49 patients (30.6%) in the neonatal cohort were receiving bowel management for fecal incontinence at most recent follow up compared to five of 33 (15.2%) in the delayed cohort (p = 0.13). CONCLUSION: delayed primary endorectal pull-through offers a safe alternative to operation in the neonatal period and appears to have, at least, equivalent functional outcomes. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Stercobilin is an end-stage metabolite of hemoglobin, a component of red blood cells. It has been found that there is a significantly lower concentration of stercobilin in the urine of people diagnosed with autism spectrum disorders, suggesting potential use as a biomarker. In vitro, we have synthesized stercobilin from its precursor bilirubin through a reduction reaction proceeded by an oxidation reaction. In addition, we have isotopically labeled the stercobilin product with deuterium using this protocol. Nuclear magnetic resonance investigations show the products of the unlabeled stercobilin (Rxn 1) and the deuterated stercobilin (Rxn 2) both had a loss of signals in the 5.0- to 7.0-ppm range indicating proper conversion to stercobilin. Changes in the multiplicity of the sp3 region of the proton nuclear magnetic resonance suggest proper deuterium incorporation. Mass spectrometry studies of Rxn 1 show a difference in fragmentation patterns than that of Rxn 2 proposing potential locations for deuterium incorporation. This isotopologue of stercobilin is stable (>6 mo), and further analysis permits investigation for its use as a biomarker and potential quantitative diagnostic probe for autism spectrum disorders.
