A time out for prayer.

Compassionate care of the surgical patient recognizes the wholeness of each individual. Patients and their caregivers come to healthcare providers with the hope of relief from pain and suffering and aspirations for the potential to feel well or be "normal" again. Many lean on their personal faith and prayer for spiritual comfort and petitions for healing. We discuss a case in which prayer is incorporated into the surgical Time Out, a scenario not uncommon in faith-based hospitals, and offer a framework to evaluate the practice that incorporates ethical principles of beneficence, non-maleficence, patient/parental autonomy, justice, and the fiduciary responsibility of the healthcare provider.

Factors Associated with Health-Related Quality of Life in Children with Intestinal Failure.

OBJECTIVE: To evaluate disease-specific and age-related factors contributing to health-related quality of life (HRQOL). in children with intestinal failure. STUDY DESIGN: A prospective study of HRQOL was performed in a regional intestinal rehabilitation program. Parent-proxy Pediatric Quality of Life Inventory surveys were administered annually to families of 91 children with intestinal failure over a 6-year period. Survey data was stratified by age and compared with pediatric HRQOL data in healthy and chronically ill populations. Linear mixed-effect models using multivariable regression were constructed to identify associations with HRQOL. RESULTS: A total of 180 surveys were completed by 91 children and their families. HRQOL scores were lowest for children ages 5-7 years (P < .001) and 8-12 years (P < .01), and these changes were primarily related to school dimension scores. In multivariable regression, age of 5 years and older and developmental delay were independently associated with lower HRQOL scores. The trend toward lower HRQOL scores parallels reference data from healthy and chronically ill children, although patients with intestinal failure scored lower than both populations at school age. CONCLUSIONS: Children with intestinal failure experience lower parent-proxy HRQOL scores in the 5-7 and 8-12 year age groups primarily related to school dimension scores. Multicenter data to validate these findings and identify interventions to improve QOL for children with intestinal failure are needed.

Attitudes Surrounding the Management of Neonates with Severe Necrotizing Enterocolitis.

OBJECTIVES: To assess providers' recommendations as to comfort care versus medical and surgical management in clinical scenarios of newborns with severe bowel loss and to assess how a variety of factors influence providers' decision making. STUDY DESIGN: We conducted a survey of pediatric surgeons and neonatologists via the American Pediatric Surgical Association and American Academy of Pediatrics Section of Neonatal-Perinatal Medicine. We examined how respondents' recommendations were affected by a variety of patient and provider factors. RESULTS: There were 288 neonatologists and 316 pediatric surgeons who responded. Irrespective of remaining bowel length, comfort care was recommended by 73% of providers for a premature infant with necrotizing enterocolitis and 54% for a full-term infant with midgut volvulus. The presence of comorbidities and earlier gestational age increased the proportion of providers recommending comfort care. Neonatologists were more likely to recommend comfort care than surgeons across all scenarios (OR, 1.45-2.00; P < .05), and this difference was more pronounced with infants born closer to term. In making these recommendations, neonatologists placed more importance on neurodevelopmental outcomes (P < .001), and surgeons emphasized experience with long-term quality of life (P < .001). CONCLUSION: Despite a contemporary survival of >90% in infants with intestinal failure, a majority of providers still recommend comfort care in infants with massive bowel loss. Significant differences were identified in clinical decision making between surgeons and neonatologists. These data reinforce the need for targeted education on long-term outcomes in intestinal failure to neonatal and surgical providers.

Novel findings of left ventricular non-compaction cardiomyopathy, microform cleft lip and poor vision in patient with SMC1A-associated Cornelia de Lange syndrome.

Relatively few patients with Cornelia de Lange syndrome (CdLS) due to SMC1A mutation have been reported, limiting understanding of the full extent of the phenotype. Compared to children with classic NIPBL-associated CdLS, patients with SMC1A-associated CdLS have a milder physical phenotype with prominent intellectual disability, high rate of cleft palate and absence of limb reductions. We present a patient with SMC1A-associated CdLS who had typical features including developmental delay, seizure disorder, feeding difficulties, hirsutism, and cleft palate. She also was found to have three novel features: (i) left ventricular non-compaction (LVNC) cardiomyopathy; (ii) microform cleft lip; and (iii) severe hyperopia and astigmatism. These features have implications regarding potential insight into the pathogenesis of the disorder, screening, and medical management. Hypertrophic cardiomyopathy has previously been reported in SMC1A-associated CdLS, but to our knowledge this is the first reported child with LVNC. Previous reports have included children with isolated clefts of the palate without involvement of the lip. When cleft palate alone is associated with a disorder, the underlying pathophysiology for clefting is sometimes secondary due to mechanical blocking of the fusion of the palatal shelves with the developing tongue. The presence of microform cleft lip in this patient suggests that the pathophysiology of clefting in SMC1A is primary rather than secondary. Few studies report ophthalmologic findings specific to SMC1A. Based on these findings, LVNC cardiomyopathy and cleft lip should be considered features of SMC1A-associated CdLS. All patients should receive echocardiogram and undergo thorough ophthalmologic evaluation as part of routine CdLS care. © 2016 Wiley Periodicals, Inc.

Neurodevelopmental and Cognitive Outcomes in Children With Intestinal Failure.

OBJECTIVES: Recent advances in medical and surgical management have led to improved long-term survival in children with intestinal failure. Yet, limited data exist on their neurodevelopmental and cognitive outcomes. The aim of the present study was to measure neurodevelopmental outcomes in children with intestinal failure. METHODS: Children enrolled in a regional intestinal failure program underwent prospective neurodevelopmental and psychometric evaluation using a validated scoring tool. Cognitive impairment was defined as a mental developmental index <70. Neurodevelopmental impairment was defined as cerebral palsy, visual or hearing impairment, or cognitive impairment. Univariate analyses were performed using the Wilcoxon rank-sum test. Data are presented as median (range). RESULTS: Fifteen children with a remnant bowel length of 18 (5-85) cm were studied at age 17 (12-67) months. Thirteen patients remained dependent on parenteral nutrition. Twelve (80%) subjects scored within the normal range on cognitive testing. Each child with cognitive impairment was noted to have additional risk factors independent of intestinal failure including cardiac arrest and extreme prematurity. On univariate analysis, cognitive impairment was associated with longer inpatient hospital stays, increased number of surgical procedures, and prematurity (P < 0.02). In total, 4 (27%) children demonstrated findings consistent with neurodevelopmental impairment. CONCLUSIONS: A majority of children with intestinal failure demonstrated normal neurodevelopmental and cognitive outcomes on psychometric testing. These data suggest that children with intestinal failure without significant comorbidity may be at low risk for long-term neurodevelopmental impairment.

Contemporary Ethical Considerations for Pediatric Metabolic and Bariatric Surgery.

BACKGROUND: The prevalence of pediatric obesity continues to increase dramatically. Though metabolic and bariatric surgery (MBS) is efficacious and is supported by high-quality data in this population, it remains underutilized. This paper aims to discuss current ethical concerns, considerations, and controversies of pediatric MBS. METHODS/RESULTS: Three case studies are utilized to illustrate ethical issues related to pediatric MBS: 1) a teenager with obesity and an unsupportive parent; 2) a teenager with morbid obesity and developmental delay; and 3) a young child with severe liver damage from hepatic steatosis. CONCLUSIONS: The prevalence of pediatric obesity is rising exponentially with more cases resistant to lifestyle modifications and medical therapies. Metabolic and bariatric surgery (MBS) in children is efficacious and should prompt thoughtful multi-disciplinary discussion to best help the patient regardless of racial, ethnic, or socioeconomic status. Decision making involves consideration of patient assent, parent/guardian consent, and balance of current and future risk. Providers caring for patients should utilize "obesity-friendly" language to lessen stigma. LEVEL OF EVIDENCE: Level V.

Prevention of Parenteral Nutrition-associated Cholestasis Using Reduced Dose Soybean Lipid Emulsion: A Multicenter Randomized Trial.

INTRODUCTION: Reducing soybean lipid emulsion (SLE) dose may prevent parenteral nutrition-associated cholestasis (PNAC) but effects on growth and neurodevelopment are unknown. The purpose of this study was to evaluate the effect of reduced dose SLE on growth and neurodevelopment. METHODS: Surgical neonates at 4 centers were randomized to standard SLE (3 g/kg/day) or reduced SLE (1 g/kg/day) over a 12-week period. Bilirubin levels and growth parameters were measured baseline and weekly while on study. The effects of time and group on direct bilirubin and growth were evaluated with a linear mixed effects model. Neurodevelopmental outcomes were assessed at 12- and 24-months corrected gestational age. RESULTS: Twenty-one individuals were randomized (standard dose = 9, reduced dose = 12). Subjects in the reduced dose group had slower rates of direct bilirubin increase and overall levels decreased earlier than those in the standard dose group. There was a trend toward a faster direct bilirubin decrease in the reduced dose group (p = 0.07 at day 84). There were no differences in the rates of change in weight (p = 0.352 at day 84) or height Z-scores (p = 0.11 at day 84) between groups. One subject in the reduced dose group had abnormal neurodevelopmental testing at 24 months. CONCLUSIONS: Surgical neonates randomized to a reduced dose of SLE had improved trends in direct bilirubin levels without clinically significant differences in overall growth and neurodevelopment. TYPE OF STUDY: Randomized Controlled Trial. LEVEL OF EVIDENCE: II.

Ultrashort bowel syndrome in children.

OBJECTIVE: Recent data have demonstrated improved survival in children with intestinal failure. We hypothesized that this trend would also be observed in children with ultrashort bowel syndrome. METHODS: A prospective database from Seattle Children's Intestinal Failure Program was used to evaluate outcomes and morbidities of consecutive patients with 10 cm or less of small bowel enrolled in the program since 2005. Data are listed as median (range). RESULTS: Five patients were identified with a bowel length of 6 (1-10) cm and follow-up of 54 (43-61) months. All children have survived and are currently between 3.5 and 5.5 years of age. One patient underwent isolated intestinal transplantation and one patient is currently listed for intestinal transplantation. The transplanted child is fully enterally fed. The other patients remain at least partially dependent on parenteral nutrition. None of these patients have current evidence of parenteral nutrition-associated liver disease. Patients have required extensive care after referral to our program, including 18 (15-32) visits to the emergency room, 152 (114-273) days of inpatient care, and 6 (5-9) central line-associated blood stream infections. CONCLUSIONS: Long-term survival in children with ultrashort bowel length is possible after referral to an intestinal failure program, although extensive medical management is required. These children may be reasonable candidates for long-standing intestinal rehabilitation as a bridge to intestinal transplantation.

Health-related quality of life in children with intestinal failure.

OBJECTIVES: Survival of infants with intestinal failure (IF) has increased in the past decade; however, data on their health-related quality of life (HRQOL) are lacking. We hypothesized that HRQOL would be lower among children with IF compared with that of healthy children. METHODS: We performed a cross-sectional study of the HRQOL of children enrolled in the outpatient intestinal rehabilitation program at Seattle Children's Hospital using the PedsQL 4.0 Generic Core Scales parent proxy-report and the Family Impact Module questionnaires. Parents were asked 2 open-ended questions pertaining to the suitability and completeness of the PedsQL to assess their and their child's HRQOL. RESULTS: Parents of 23 children with IF completed the questionnaires. Compared with norms for healthy children, parents reported significantly lower total PedsQL scores for children ages 1 to 2 years (mean difference -13.16, 95% confidence interval [CI] -21.86 to -4.46; P = 0.003) and 2 to 6 years (mean difference -15.57, 95% CI -22.66 to -8.48; P < 0.001). Scores were also lower for children younger than 1 year (mean difference -6.43, 95% CI -13.93 to 1.07), although this test was not statistically significant. No measured demographic or clinical characteristics were associated with HRQOL. The majority of parents (65%) said the PedsQL failed to address important effects of IF on children and their families. CONCLUSIONS: Children with IF and their parents have a decreased HRQOL compared with healthy children as measured by the PedsQL survey. A disease-specific module or separate HRQOL questionnaire is needed for a more comprehensive assessment of HRQOL in children with IF.

Chest Tube Management following Lung Resection in Pediatric Patients: A Retrospective Analysis.

BACKGROUND: Pleural drainage following lung resection is almost universally practiced in pediatric surgery, but its necessity has been questioned in adult literature. We performed a cross-sectional study of pediatric patients undergoing lung resection to characterize chest tube (CT) practices and clarify their utility. METHOD: Retrospective chart review of patients <21 years of age undergoing pulmonary lobectomy or wedge resection at an academic children's hospital from 2013 to 2022. Variables regarding demographics and post-operative CT management were recorded. RESULTS: 130 procedures meet inclusion criteria: 59 lobectomies (group 1), 19 diagnostic wedges (group 2), and 52 excisional wedges (group 3). 74.6% of group 1 patients had no air leak, and median CT duration was 2 days. In group 2, 89.5% had no air leak and median CT duration was 1 day. In Group 3, 80.8% had no air leak and median CT duration was 1 day. Overall, 43.1% patients had their CT removed on post-operative day 1 and 21.5% on post-operative day 2. CONCLUSION: CT duration following lung resection in pediatric patients is typically brief, with most patients having no air leak and CT removal within 2 days of surgery. Obligatory CT drainage may not be necessary in select patients undergoing lung resection. LEVEL OF EVIDENCE: Level IV. TYPE OF STUDY: Retrospective Study.

Colocolonic intussusception in a four-yr-old with a heart transplant: a case report and review of the literature.

A rare case of a colocolonic intussusception in a pediatric cardiac transplant patient is reported along with a review of colocolonic intussusception in pediatric patients after organ transplantation. A four-yr-old girl with a history of heart transplantation shortly after birth presented with a 12-hour history of abdominal pain, vomiting, and bloody stools. Initial abdominal x-ray showed rectal edema. A rectal examination revealed a palpable intussusceptum that prompted a therapeutic contrast enema, which failed to reduce the intussusception. Surgical exploration was performed with reduction of the intussusception and resection of the terminal ileum and cecum. A pathologic lead point was not identified.

Hidden attraction: a menacing meal of magnets and batteries.

BACKGROUND: Magnet and button battery ingestions are increasingly common, and can result in significant morbidity. Timely identification of hazardous foreign body ingestions can be difficult in non-verbal and non-disclosing children. OBJECTIVES: We aim to present a case that demonstrates some of the challenges around identifying and correctly locating magnets and batteries, and the importance of prompt identification and removal. CASE REPORT: We describe an older child with the covert ingestion of multiple magnets and batteries, with magnets that attracted across the stomach and a loop of jejunum. Mild symptoms and signs resulted in a delayed diagnosis and serious consequences. Radiographs suggested a gastric location of the foreign bodies. CONCLUSION: Health care workers should consider the possibility of battery or magnet ingestions in children with vomiting and abdominal pain, even when well-appearing. Like esophageal batteries, multiple gastrointestinal magnets and combined magnet-battery ingestions can cause significant morbidity, and prompt identification is important. Providers should ask verbal children for ingestion histories, and consider radiographs when symptoms are atypical or persistent. Like esophageal batteries, gastrointestinal magnet-battery ingestions should be removed promptly to prevent complications. Caregivers should supervise or limit the use of toys that include magnets and batteries.

Medical and Surgical Aspects of Intestinal Failure in the Child.

Medical and surgical care for children with intestinal failure has evolved so that long-term life expectancy is common even in the setting of the shortest bowel lengths. The long-term administration of parenteral nutrition has become safe with alterations in lipid formulation, and the risk of liver injury has been dramatically reduced. Well-established techniques for bowel lengthening and tapering exist to increase the absorptive capacity of the remnant bowel. These advances allow for ongoing intestinal rehabilitation in the child with the ultimate goal of enteral autonomy while the use of intestinal transplantation in this population has declined in recent years.

Child self-reported quality of life in pediatric intestinal failure.

BACKGROUND: Recent studies have focused on parent-reported health-related quality of life (HRQOL) in children with intestinal failure (IF). However, there is a paucity of data on HRQOL from the perspective of the child with IF. METHODS: A prospective study of child self-reported HRQOL was performed in a regional intestinal rehabilitation program from 2015 to 2019. The PedsQL 4.0 Generic Core Scales were administered annually to children with IF ages five years and older along with their parents. Survey data was stratified by age and compared with parent-proxy scores and reference populations of healthy and chronically ill children. Linear mixed-effect models were constructed to identify associations with child self-reported HRQOL. RESULTS: A total of 140 surveys were administered to 69 children and their parents. Median child age at survey was 8 (IQR 6-10) years. Child self-reported HRQOL scores increased with each increasing age range. Children reported higher HRQOL scores compared to parent-proxy data in all age groups. Children with IF had lower HRQOL scores compared to healthy children in all survey dimensions (p < 0.001) and to children with chronic illness in the school and social functioning dimensions (p < 0.05). In adjusted analysis, longer remnant bowel length was independently associated with decreased HRQOL scores in children (p < 0.05). CONCLUSIONS: Children with IF reported better HRQOL compared to parent-proxy data. While these HRQOL scores improved with age, they remain significantly lower than healthy and chronically ill peers. The association between bowel length and child-reported HRQOL deserves further investigation. LEVEL OF EVIDENCE: Level II.

The role of feeding advancement strategy on length of stay and hospital costs in newborns with gastroschisis.

BACKGROUND: Infants with gastroschisis require prolonged hospitalization for surgical repair and gradual advancement of feeds. The present study explores the effect of a change in a protocolized enteral feeding regimen with length of hospital stay (LOS) and total costs in newborns with gastroschisis. METHODS: A retrospective review was performed in neonates with uncomplicated gastroschisis at a free-standing pediatric institution from 2012 to 2020. The effect of two different enteral feed advancement protocols on clinical outcomes and hospital costs was analyzed. RESULTS: Seventy-four patients were identified, of which 50 (68%) underwent 10 ml/kg/day feeding advancements, and 24 (32%) underwent 20 ml/kg/day feeding advancements. Compared to neonates who underwent 10 ml/kg/day enteral advancements, neonates receiving 20 ml/kg/day advancements reached goal feeds faster (14 vs 20 days, p<0.001), were younger at goal feeds (26 vs 34 days, p = 0.001), required fewer days of parenteral nutrition (22 vs 29 days, p = 0.001), and had shorter LOS (30 vs 36 days, p = 0.001). On multivariable analysis, total costs decreased by 9.77% in the 20 ml/kg/day advancement cohort (p = 0.071). CONCLUSION: In neonates with uncomplicated gastroschisis who underwent primary repair, a nutritional protocol that incorporated 20 ml/kg/day feeding advancements was safe and resulted in faster attainment of goal feeds and shorter LOS. LEVEL OF EVIDENCE: II/III.

Ethical dilemmas in the management of infants with necrotizing enterocolitis totalis.

PURPOSE: Necrotizing enterocolitis (NEC) totalis is a devastating disease of the newborn intestine. A precise clinical definition of the extent of gastrointestinal involvement is lacking in the existing literature, and the clinical outcomes are typically viewed as grim. METHODS: Herein, we present a series of clinical case examples of patients with varying degrees of NEC totalis and other co-morbid conditions, with possible anticipated outcomes based on current data. RESULTS: We define the key ethical issues and provide a framework and discussion of the ethical issues involved in the care of patients with NEC totalis and recommendations of how to approach discussions with the family of these patients We discuss the ethical considerations for both the providers caring for these patients, and the patient's family members. CONCLUSION: The management of patients with NEC totalis is complex and ethically challenging. LEVEL OF EVIDENCE: V.

Prospective evaluation of the family's health-related quality of life in pediatric intestinal failure.

BACKGROUND: Due to altered nutrition regimens and complex medical needs, pediatric intestinal failure (IF) may have a powerful impact on health-related quality of life (HRQOL). Studies have shown that children with IF experience lower HRQOL. Data on the HRQOL of families of children with IF are lacking. METHODS: We performed a prospective analysis of the HRQOL of families of children with IF in a regional intestinal rehabilitation program from 2011 to 2018. The Pediatric Quality of Life Family Impact Module (FIM) was administered annually to parents. FIM scores were regressed on risk factors using linear mixed-effect models that accounted for repeated surveys within families. RESULTS: A total of 117 families completed 272 surveys. FIM scores increased with patient age across nearly all survey dimensions. Total FIM scores were lower when compared to families of healthy children (median differences = -5, P = .01) and similar to families of chronically ill children. While IF families reported major deficits in the Communication (-11, P < .001) and Worry (-17, P < .001) dimensions, they also reported higher Family Relationship scores (+7, P < .01). On multivariable regression, presence of a major comorbidity and four or more hospital admissions in the prior year were associated with lower family HRQOL (P < .05). Parenteral nutrition dependence was independently associated with lower scores in the Communication (-7, P = .03) and Daily Activities (-10, P = .02) dimensions. CONCLUSION: Families of children with IF experience a decreased HRQOL that may improve with patient age. Intestinal rehabilitation programs should address the HRQOL of families in addition to patients.

Is the changing landscape of fellowship recruitment during COVID-19 here to stay?

BACKGROUND: The 2020 Pediatric Surgery (PS) fellowship selection process was heavily impacted by the COVID-19 pandemic. A review of lessons learned can help determine best practices for the future. The purpose of the study was to analyze the virtual interview experience and assess opportunities to improve the post-pandemic fellowship recruitment process. STUDY DESIGN: Using a 28-question survey of Program Directors (PDs) of PS fellowships as well as a 44-question survey of applicants to PS fellowships in the US and Canada, we gathered information on the recruitment process during the COVID-19 pandemic (2020). Dichotomous, multiple choice and open-ended questions about the changes in process, platforms used, format, comparison to on-site interviews and overall satisfaction were used for objective and subjective feedback. RESULTS: A 95% participation rate was recorded for the PD survey. 24 out of 55 programs (44%) changed their on-site interviews to virtual format due to the pandemic. Most PDs described their overall impression of virtual interviews as satisfactory (66%, 16/24) and did not have an impact on the applicant's success in the match (35/54; 65%). About 50% of PDs preferred to have on-site interviews with virtual screening in the future. While the participation rate from applicants was much less (26 of 70), responses confirmed our survey results. Majority preferred on-site interviews (17/26), 6 of which preferred virtual screening followed by on-site interviews. CONCLUSION: Components of virtual screening and interviews were found to have benefits financially and from both time and stress perspectives, and thus might survive past the pandemic.

Pediatric surgery milestones 2.0: A primer.

More than twenty years ago, the Accreditation Council for Graduate Medical Education and the American Board of Medical Specialties began the conversion of graduate medical education from a structure- and process-based model to a competency-based framework. The educational outcomes assessment tool, known as the Milestones, was introduced in 2013 for seven specialties and by 2015 for the remaining specialties, including pediatric surgery. Designed to be an iterative process with improvements over time based on feedback and evidence-based literature, the Milestones started the evolution from 1.0 to 2.0 in 2016. The formation of Pediatric Surgery Milestones 2.0 began in 2019 and was finalized in 2021 for implementation in the 2022-2023 academic year. Milestones 2.0 are fewer in number and are stated in more straightforward language. It incorporated the harmonized milestones, subcompetencies for non-patient care and non-medical knowledge that are consistent across all medical and surgical specialties. There is a new Supplemental Guide that lists examples, references and links to other assessment tools and resources for each subcompetency. Milestones 2.0 represents a continuous process of feedback, literature review and revision with goals of improving patient care and maintaining public trust in graduate medical education's ability to self-regulate.

Success in pediatric surgery: An updated survey of Program Directors 2020.

BACKGROUND: One of the most competitive surgical sub-specialty fellowships remains Pediatric Surgery (PS), which requires candidates to develop a strong and research-oriented curriculum vitae. Although some objective factors of matriculation are known, factors for the interview selection and ranking per the program directors (PDs) have not been reviewed in over a decade. METHODS: A web-based survey of US and Canadian PS program directors (PDs) (n = 58) was used to evaluate a comprehensive list of factors in the selection criteria for PS fellowships. A mix of dichotomous, ranking, five-point Likert scale, and open-ended questions evaluated applicant characteristics, ABSITE scores, research productivity, interview day, and rank order criteria. RESULTS: Fifty-five programs responded to the survey for a 95% participation rate. PDs desired an average of two years in dedicated research and weighted first authorship and total number of publications heavily. Only 38% of programs used an ABSITE score cutoff for offering interviews; however, the majority agreed that an overall upward trend was important. Quality letters of recommendation, especially from known colleagues, carried weight when deciding to offer interviews. Interview performance, being a team player, observed interpersonal interactions, perceived operative skills and patient care, and leadership were some of the notable factors when finalizing rank lists. CONCLUSIONS: A multitude of factors define a successful matriculant, including quality of letters of recommendation, quality and quantity of publications, supportive phone calls, observed interactions, interview performance, perceptions of being team player with leadership skills as well as perceptions of good operative skills and patient care.
