Lack of Association of Pediatric Surgical Patient Outcomes With Increased Disposable Operating Room Supply Costs.

INTRODUCTION: There is wide variation in the cost of disposable operating room supplies between surgeons performing the same operation at the same institution. The general relationship between variation in disposable supply cost and patient outcomes is unknown. We aimed to evaluate the relationship between disposable supply cost and patient outcomes for sixteen common operations. METHODS: Cost data were reviewed for the most common procedures performed by five surgical divisions at a single children's hospital over a six-month period in 2021. For procedure, the median disposable OR costs were calculated. Each operation performed was categorized as low cost (below the group median) or high cost (above the group median. We compared the rates of adverse events (clinic visit within 5 days, 30-day emergency department visit, unplanned reoperation, unplanned readmission, anesthesia complications, prolonged hospital length of stay, need for blood product transfusion, or death) between procedures with low and high disposable supply costs. RESULTS: 1139 operations performed by 48 unique surgeons from five specialties were included; 596 (52%) were low-cost and 543 (48%) high-cost. The low and high-cost groups did not differ regarding most demographic characteristics. Overall, 21.9% of children suffered any adverse outcome; this rate did not differ between the low and high-cost groups when evaluated individually or in aggregate (20.5% vs 23.6%, p = 0.23). CONCLUSION: Our data demonstrate that across a wide range of pediatric surgical procedures, the cost of disposable operating room supplies was not associated with the risk of adverse outcomes.

Effect of Early vs Late Inguinal Hernia Repair on Serious Adverse Event Rates in Preterm Infants: A Randomized Clinical Trial.

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

Association of Sociodemographic Factors with Surgical Management of Hepatoblastoma and Hepatocellular Carcinoma in Children.

OBJECTIVE: To evaluate for disparities in surgical care among US children with hepatoblastoma (HB) and hepatocellular carcinoma (HCC). STUDY DESIGN: In this retrospective National Cancer Database study (2004-2015), children aged <18 years with HB or HCC were included. Multivariable mixed-effects logistic regression was used to evaluate the association of sociodemographic factors (age, sex, race and ethnicity, insurance status, income, proximity to treating hospital) with the odds of undergoing surgical treatment after adjusting for disease-related factors (tumor size, metastasis, comorbidities) and hospital-level effects. Subgroup analyses by tumor histology were performed. RESULTS: A total of 811 children were included (HB: 80.9%; HCC: 19.1%), of which 610 (75.2%) underwent surgical treatment. Following adjustment, decreased odds of undergoing surgical treatment were associated with Black race (OR: 0.46 vs White, 95% CI [95% CI]: 0.26-0.80, P = .01), and having Medicaid (OR: 0.58 vs private, 95% CI: 0.38-0.88, P = .01) or no insurance (OR: 0.33 vs private, 95% CI: 0.13-0.80, P = .02). In children with HB, Black race was associated with decreased odds of undergoing surgical treatment (OR: 0.47 vs White, 95% CI: 0.25-0.89, P = .02). In children with HCC, Medicaid (OR: 0.10 vs private, 95% CI: 0.03-0.35, P < .001), or no insurance status (OR: 0.10 vs private, 95% CI: 0.01-0.83, P = .03) were associated with decreased odds of undergoing surgical treatment. Other than metastatic disease, no additional factors were associated with likelihood of surgical treatment in any group. CONCLUSIONS: Black race and having Medicaid or no insurance are independently associated with decreased odds of surgical treatment in children with HB and HCC, respectively. These children may be less likely to undergo curative surgery for their liver cancer.

Delphi Process for Validation of Fluid Treatment Algorithm for Critically Ill Pediatric Trauma Patients.

INTRODUCTION: While intravenous fluid therapy is essential to re-establishing volume status in children who have experienced trauma, aggressive resuscitation can lead to various complications. There remains a lack of consensus on whether pediatric trauma patients will benefit from a liberal or restrictive crystalloid resuscitation approach and how to optimally identify and transition between fluid phases. METHODS: A panel was comprised of physicians with expertise in pediatric trauma, critical care, and emergency medicine. A three-round Delphi process was conducted via an online survey, with each round being followed by a live video conference. Experts agreed or disagreed with each aspect of the proposed fluid management algorithm on a five-level Likert scale. The group opinion level defined an algorithm parameter's acceptance or rejection with greater than 75% agreement resulting in acceptance and greater than 50% disagreement resulting in rejection. The remaining were discussed and re-presented in the next round. RESULTS: Fourteen experts from five Level 1 pediatric trauma centers representing three subspecialties were included. Responses were received from 13/14 participants (93%). In round 1, 64% of the parameters were accepted, while the remaining 36% were discussed and re-presented. In round 2, 90% of the parameters were accepted. Following round 3, there was 100% acceptance by all the experts on the revised and final version of the algorithm. CONCLUSIONS: We present a validated algorithm for intavenous fluid management in pediatric trauma patients that focuses on the de-escalation of fluids. Focusing on this time point of fluid therapy will help minimize iatrogenic complications of crystalloid fluids within this patient population.

Hepatic Metastasectomy in Pediatric Patients: An Observational Study.

BACKGROUND: The role of hepatectomy for metastatic disease in children is controversial. Rationales include potential cure, obtaining a diagnosis, and guiding chemotherapy decisions. This study examines the safety and utility of hepatic metastasectomy for children at a single institution. METHODS: After IRB approval (#22-1258), medical records were reviewed from 1995 to 2022 for children undergoing hepatic metastasectomy. En-bloc hepatectomies during primary tumor resection were excluded. RESULTS: Hepatic metastasectomy was performed in 16 patients for a variety of histologies. Median patient age was 12.2 years [IQR 6.9-22.6], and 13/16 patients were female (81 %). Number of hepatic metastases ranged from 1 to 23 and involved between 1 and 8 Couinaud segments. Anatomic resections included 4 hemihepatectomies and 1 sectionectomy. All other resections were nonanatomic. 3/6 resections for germ cell tumor (GCT) revealed only mature teratoma, driving adjuvant therapy decisions. When indicated, median time to adjuvant chemotherapy was 19 days [IQR 11-22]. No patients had Clavien-Dindo Class III or higher perioperative morbidity. Three patients (1 GCT, 1 adrenocortical carcinoma (ACC), and 1 gastric neuroendocrine tumor (GNET) experienced hepatic relapse. The patients with relapsed GCT and GNET are alive with disease at 17 and 135 months, respectively. The patient with ACC died of disease progression and liver failure. One patient with Wilms tumor experienced extrahepatic, retroperitoneal recurrence and died. With a median follow-up of 38 months, 10-year disease-specific and disease-free survival were 77 % and 61 %, respectively. CONCLUSIONS: Hepatic metastasectomy can be accomplished safely in children, may guide adjuvant therapy decisions, and is associated with long-term survival in selected patients. LEVEL OF EVIDENCE: Level IV. TYPE OF STUDY: Treatment Study, Case series with no comparison group.

Hirschsprung disease.

Hirschsprung disease (HSCR) is a rare congenital intestinal disease that occurs in 1 in 5,000 live births. HSCR is characterized by the absence of ganglion cells in the myenteric and submucosal plexuses of the intestine. Most patients present during the neonatal period with the first meconium passage delayed beyond 24 h, abdominal distension and vomiting. Syndromes associated with HSCR include trisomy 21, Mowat-Wilson syndrome, congenital central hypoventilation syndrome, Shah-Waardenburg syndrome and cartilage-hair hypoplasia. Multiple putative genes are involved in familial and isolated HSCR, of which the most common are the RET proto-oncogene and EDNRB. Diagnosis consists of visualization of a transition zone on contrast enema and confirmation via rectal biopsy. HSCR is typically managed by surgical removal of the aganglionic bowel and reconstruction of the intestinal tract by connecting the normally innervated bowel down to the anus while preserving normal sphincter function. Several procedures, namely Swenson, Soave and Duhamel procedures, can be undertaken and may include a laparoscopically assisted approach. Short-term and long-term comorbidities include persistent obstructive symptoms, enterocolitis and soiling. Continued research and innovation to better understand disease mechanisms holds promise for developing novel techniques for diagnosis and therapy, and improving outcomes in patients.

Altered hepatic and intestinal homeostasis in a neonatal murine model of short-term total parenteral nutrition and antibiotics.

Parenteral nutrition (PN) prevents starvation and supports metabolic requirements intravenously when patients are unable to be fed enterally. Clinically, infants are frequently provided PN in intensive care settings along with exposure to antibiotics (ABX) to minimize infection during care. Unfortunately, neonates experience extremely high rates of hepatic complications. Adult rodent and piglet models of PN are well-established but neonatal models capable of leveraging the considerable transgenic potential of the mouse remain underdeveloped. Utilizing our newly established neonatal murine PN mouse model, we administered ABX or controlled drinking water to timed pregnant dams to disrupt the maternal microbiome. We randomized mouse pups to PN or sham surgery controls +/- ABX exposure. ABX or short-term PN decreased liver and brain organ weights, intestinal length, and mucosal architecture (vs. controls). PN significantly elevated evidence of hepatic proinflammatory markers, neutrophils and macrophage counts, bacterial colony-forming units, and evidence of cholestasis risk, which was blocked by ABX. However, ABX uniquely elevated metabolic regulatory genes resulting in accumulation of hepatocyte lipids, triglycerides, and elevated tauro-chenoxycholic acid (TCDCA) in serum. Within the gut, PN elevated the relative abundance of Akkermansia, Enterococcus, and Suterella with decreased Anaerostipes and Lactobacillus compared with controls, whereas ABX enriched Proteobacteria. We conclude that short-term PN elevates hepatic inflammatory stress and risk of cholestasis in early life. Although concurrent ABX exposure protects against hepatic immune activation during PN, the dual exposure modulates metabolism and may contribute toward early steatosis phenotype, sometimes observed in infants unable to wean from PN.NEW & NOTEWORTHY This study successfully established a translationally relevant, murine neonatal parenteral nutrition (PN) model. Short-term PN is sufficient to induce hepatitis-associated cholestasis in a neonatal murine model that can be used to understand disease in early life. The administration of antibiotics during PN protects animals from bacterial translocation and proinflammatory responses but induces unique metabolic shifts that may predispose the liver toward early steatosis.

Paneth cell dysfunction in radiation injury and radio-mitigation by human α-defensin 5.

Introduction: The mechanism underlying radiation-induced gut microbiota dysbiosis is undefined. This study examined the effect of radiation on the intestinal Paneth cell α-defensin expression and its impact on microbiota composition and mucosal tissue injury and evaluated the radio-mitigative effect of human α-defensin 5 (HD5). Methods: Adult mice were subjected to total body irradiation, and Paneth cell α-defensin expression was evaluated by measuring α-defensin mRNA by RT-PCR and α-defensin peptide levels by mass spectrometry. Vascular-to-luminal flux of FITC-inulin was measured to evaluate intestinal mucosal permeability and endotoxemia by measuring plasma lipopolysaccharide. HD5 was administered in a liquid diet 24 hours before or after irradiation. Gut microbiota was analyzed by 16S rRNA sequencing. Intestinal epithelial junctions were analyzed by immunofluorescence confocal microscopy and mucosal inflammatory response by cytokine expression. Systemic inflammation was evaluated by measuring plasma cytokine levels. Results: Ionizing radiation reduced the Paneth cell α-defensin expression and depleted α-defensin peptides in the intestinal lumen. α-Defensin down-regulation was associated with the time-dependent alteration of gut microbiota composition, increased gut permeability, and endotoxemia. Administration of human α-defensin 5 (HD5) in the diet 24 hours before irradiation (prophylactic) significantly blocked radiation-induced gut microbiota dysbiosis, disruption of intestinal epithelial tight junction and adherens junction, mucosal barrier dysfunction, and mucosal inflammatory response. HD5, administered 24 hours after irradiation (treatment), reversed radiation-induced microbiota dysbiosis, tight junction and adherens junction disruption, and barrier dysfunction. Furthermore, HD5 treatment also prevents and reverses radiation-induced endotoxemia and systemic inflammation. Conclusion: These data demonstrate that radiation induces Paneth cell dysfunction in the intestine, and HD5 feeding prevents and mitigates radiation-induced intestinal mucosal injury, endotoxemia, and systemic inflammation.

Providers' Perceptions Versus Practices Inform Pediatric Colorectal Enhanced Recovery After Surgery Implementation.

INTRODUCTION: There are many barriers to the implementation of an enhanced recovery after surgery (ERAS) pathway. The aim of this study was to compare surgeon and anesthesia perceptions with current practices prior to the initiation of an ERAS protocol in pediatric colorectal patients and to use that information to inform ERAS implementation. METHODS: This was a mixed method single institution study of barriers to implementation of an ERAS pathway at a free-standing children's hospital. Anesthesiologists and surgeons at a free-standing children's hospital were surveyed regarding current practices of ERAS components. A retrospective chart review was performed of 5- to 18-y-old patients undergoing colorectal procedures between 2013 and 2017, followed by the initiation of an ERAS pathway, and a prospective chart review for 18 mo postimplementation. RESULTS: The response rate was 100% (n = 7) for surgeons and 60% (n = 9) for anesthesiologists. Preoperative nonopioid analgesics and regional anesthesia were rarely used. Intraoperatively, 54.7% of patients had a fluid balance of <10 cc/kg/h and normothermia was achieved in only 38.7%. Mechanical bowel prep was frequently utilized (48%). Median nil per os time was significantly longer than required at 12 h. Postoperatively, 42.9% of surgeons reported that patients could have clears on postoperative day zero, 28.6% on postoperative day one, and 28.6% after flatus. In reality, 53.3% of patients were started on clears after flatus, with a median time of 2 d. Most surgeons (85.7%) expected patients to get out of bed once awake from anesthesia; however, median time that patients were out of bed was postoperative day one. While most surgeons reported frequent use of acetaminophen and/or ketorolac, only 69.3% received any nonopioid analgesic postoperatively, with only 41.3% receiving two or more nonopioid analgesics. Nonopioid analgesia showed the highest rates of improvement from retrospective to prospective: preoperative use of analgesics increased from 5.3% to 41.2% (P < 0.0001), postoperative use of acetaminophen increased by 27.4% (P = 0.5), Toradol by 45.5% (P = 0.11), and gabapentin by 86.7% (P < 0.0001). Postoperative nausea/vomiting prophylaxis with >1 class of antiemetic increased from 8% to 47.1% (P < 0.001). The length of stay was unchanged (5.7 versus 4.4 d, P = 0.14). CONCLUSIONS: For the successful implementation of an ERAS protocol, perceptions versus reality must be assessed to determine current practices and identify barriers to implementation.

Impact of institutional prophylaxis guidelines on rates of pediatric venous thromboembolism following trauma-A multicenter study from the pediatric trauma society research committee.

BACKGROUND: A paucity of data exists with regard to the incidence, management, and outcomes of venous thromboembolism (VTE) in injured children. We sought to determine the impact of institutional chemoprophylaxis guidelines on VTE rates in a pediatric trauma population. METHODS: A retrospective review of injured children (≤15 years) admitted between 2009 and 2018 at 10 pediatric trauma centers was performed. Data were gathered from institutional trauma registries and dedicated chart review. The institutions were surveyed as to whether they had chemoprophylaxis guidelines in place for high-risk pediatric trauma patients, and outcomes were compared based on the presence of guidelines using χ 2 analysis ( p < 0.05). RESULTS: There were 45,202 patients evaluated during the study period. Three institutions (28,359 patients, 63%) had established chemoprophylaxis policies during the study period ("Guidelines"); the other seven centers (16,843 patients, 37%) had no such guidelines ("Standard"). There were significantly lower rates of VTE in the Guidelines group, but these patients also had significantly fewer risk factors. Among critically injured children with similar clinical presentations, there was no difference in VTE rate. Specifically within the Guidelines group, 30 children developed VTE. The majority (17/30) were actually not indicated for chemoprophylaxis based on institutional guidelines. Still, despite protocols only one VTE patient in the guidelines group who was indicated for intervention ended up receiving chemoprophylaxis prior to diagnosis. No consistent ultrasound screening protocol was in place at any institution during the study. CONCLUSION: The presence of an institutional policy to guide chemoprophylaxis for injured children is associated with a decreased overall frequency of VTE, but this disappears when controlling for patient factors. However, the overall efficacy is impacted by a combination of deficits in guideline compliance and structure. Further prospective data are needed to help determine the ideal role for chemoprophylaxis and protocols in pediatric trauma. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Upper Gastrointestinal Series in the Workup for Pediatric Gastrostomy Placement: Does it Delay Care?

INTRODUCTION: Upper gastrointestinal (UGI) series is often part of the workup prior to the placement of gastrostomy tubes in children. Prior studies have suggested UGI to be limited in utility and an extra financial burden. The goal of this study was to investigate the utility and cost of UGI studies. METHODS: A retrospective, case control study of patients aged < 18 y receiving gastrostomy tubes at a free-standing children's hospital between 2012 and 2017. Total costs were obtained from the Pediatric Health Information System. RESULTS: Six hundred eighty five patients underwent gastrostomy placement during the study period. UGI was obtained in 90.8% of patients; 23.6% of studies were abnormal. The most common abnormal findings were reflux (13.8%) and abnormal anatomy (5.8%). The median time to obtain a UGI was 0.82 d (interquartile range 0.22-1.05). Obtaining a UGI was associated with delayed care in 104 patients (15.2%). If a delay was encountered, median time was 2.47 d (interquartile range 1.86-2.99). Ladd's procedures were performed in 12 patients (1.7%) found to have malrotation on UGI. None of the 63 patients who did not undergo UGI required a Ladd's procedure. Patients that had a UGI did not experience an increase in overall length of stay (14.3 versus 15.6 d, excluding intensive care unit patients), operative time (34 versus 39 min), or a change in rate of operative complications (11.5% versus 14.3%). In addition, UGI did not have a significant impact on total adjusted costs ($49,844 versus $83,438 without UGI, P = 0.12) but did slightly increase total adjusted costs per day ($2212 versus $1999 without UGI, P = 0.01). CONCLUSIONS: UGI prior to gastrostomy placement in children rarely identified abnormal findings that changed the operative plan, was associated with delayed care in 15% of patients, and was associated with slightly increased costs per day. Further analyses to identify subsets of children that may benefit from routine UGI are warranted.

Readability of patient and family education materials on pediatric surgical association websites.

PURPOSE: Globally, pediatric surgical association websites present patient/family education materials on an extensive list of conditions, including descriptions of the condition, signs and symptoms, diagnostic modalities, and treatment options. The purpose of this project was to assess the readability of pediatric surgical association websites' patient/family education materials. METHODS: With IRB approval, we accessed all patient/family education materials on pediatric surgical association websites from around the globe and used multiple grade-level assessments and readability assessments to determine the reading level at which the information is presented. RESULTS: The American Pediatric Surgical Association (APSA) website and the British Association of Paediatric Surgeons (BAPS) present publicly accessible patient/family education materials. Seventy-four (74) conditions on APSA's website were analyzed. Three grade-level assessments and the Flesch Reading Ease assessment indicated that the articles are written at high school reading levels. No articles were available in languages other than English. BAPS presented 6 conditions, most of which were more readable than their APSA counterparts. CONCLUSIONS: Our analysis indicates that the patient/family education materials available on pediatric surgical association websites may not be written at a level that is comprehensible by the general population. Potential solutions include re-writing the materials with an emphasis on readability and presenting materials in languages other than English. LEVEL OF EVIDENCE: V.

Aggressive Pursuit of No Evidence of Disease Status in Hepatoblastoma Improves Survival: An Observational Study.

BACKGROUND: The utility of repeated surgical interventions in hepatoblastoma to achieve no evidence of disease (NED) is not well-defined. We examined the effect of aggressive pursuit of NED status on event-free (EFS) and overall survival (OS) in hepatoblastoma with subgroup analysis of high-risk patients. METHODS: Hospital records were queried for patients with hepatoblastoma from 2005 to 2021. Primary outcomes were OS and EFS stratified by risk and NED status. Group comparisons were performed using univariate analysis and simple logistic regression. Survival differences were compared with log-rank tests. RESULTS: Fifty consecutive patients with hepatoblastoma were treated. Forty-one (82%) were rendered NED. NED was inversely correlated with 5-year mortality (OR 0.006; CI 0.001-0.056; P < .01). Ten-year OS (P < .01) and EFS (P < .01) were improved by achieving NED. Ten-year OS was similar between 24 high-risk and 26 not high-risk patients when NED was attained (P = .83). Fourteen high-risk patients underwent a median of 2.5 pulmonary metastasectomies, 7 for unilateral disease, and 7 for bilateral, with a median of 4.5 nodules resected. Five high-risk patients relapsed, and three were salvaged. CONCLUSIONS: NED status is necessary for survival in hepatoblastoma. Repeated pulmonary metastasectomy and/or complex local control strategies to obtain NED can achieve long-term survival in high-risk patients.

Hirschsprung-associated inflammatory bowel disease: A multicenter study from the APSA Hirschsprung disease interest group.

BACKGROUND/PURPOSE: A small number of Hirschsprung disease (HD) patients develop inflammatory bowel disease (IBD)-like symptoms after pullthrough surgery. The etiology and pathophysiology of Hirschsprung-associated IBD (HD-IBD) remains unknown. This study aims to further characterize HD-IBD, to identify potential risk factors and to evaluate response to treatment in a large group of patients. METHODS: Retrospective study of patients diagnosed with IBD after pullthrough surgery between 2000 and 2021 at 17 institutions. Data regarding clinical presentation and course of HD and IBD were reviewed. Effectiveness of medical therapy for IBD was recorded using a Likert scale. RESULTS: There were 55 patients (78% male). 50% (n = 28) had long segment disease. Hirschsprung-associated enterocolitis (HAEC) was reported in 68% (n = 36). Ten patients (18%) had Trisomy 21. IBD was diagnosed after age 5 in 63% (n = 34). IBD presentation consisted of colonic or small bowel inflammation resembling IBD in 69% (n = 38), unexplained or persistent fistula in 18% (n = 10) and unexplained HAEC >5 years old or unresponsive to standard treatment in 13% (n = 7). Biological agents were the most effective (80%) medications. A third of patients required a surgical procedure for IBD. CONCLUSION: More than half of the patients were diagnosed with HD-IBD after 5 years old. Long segment disease, HAEC after pull through operation and trisomy 21 may represent risk factors for this condition. Investigation for possible IBD should be considered in children with unexplained fistulae, HAEC beyond the age of 5 or unresponsive to standard therapy, and symptoms suggestive of IBD. Biological agents were the most effective medical treatment. LEVEL OF EVIDENCE: Level 4.

Management of pediatric appendicitis during the COVID-19 pandemic: A nationwide multicenter cohort study.

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

Pregnancy During Surgical Training: Are Residency Programs Truly Supporting Their Trainees?

OBJECTIVE: Despite recent national improvements in family leave policies, there has been little focus on program-level support for surgical trainees. Trainees who may require clinical duty adjustments during pregnancy, who experience pregnancy loss, or who struggle with balancing work obligations with the demands of a new infant may face stigma when seeking schedule accommodations. The aim of this study was to describe program and colleague support of surgical trainees for pregnancy-related and postpartum health needs. DESIGN: Survey questionnaire. Participants responded to multiple-choice questions about their history of pregnancy loss, their experience with reduction of clinical duties during pregnancy, and their breastfeeding experience. Those who took time off after miscarriages or reduced their clinical duties during pregnancy were asked whether they perceived their colleagues and/or program leadership to be supportive using a 4-point Likert scale (1-strongly agree, 4-strongly disagree) which was dichotomized to agree/disagree. SETTING: Electronically distributed through social media and surgical societies from November 2020 to January 2021. PARTICIPANTS: Female surgical residents and fellows. RESULTS: 258 female surgical residents and fellows were included. Median age was 32 (IQR 30-35) years and 76.74% were white. Of the 52 respondents (20.2%) who reported a miscarriage, 38 (73.1%) took no time off after pregnancy loss, including 5 of 10 women (50%) whose loss occurred after 10 weeks' gestation. Of the 14 residents who took time off after a miscarriage, 4 (28.6%) disagreed their colleagues and/or leadership were supportive of time away from work. Among trainees who reported at least 1 live birth, only 18/114 (15.8%) reduced their work schedule during pregnancy. Of these, 11 (61.1%) described stigma and resentment from colleagues and 14 (77.8%) reported feeling guilty about burdening their colleagues. 100% of respondents reported a desire to breastfeed their infants, but nearly half (46.0%) were unable to reach their breastfeeding goals. 46 (80.7%) cited a lack of time to express breastmilk and 23 (40.4%) cited inadequate lactation facilities as barriers to achieving their breastfeeding goals. CONCLUSIONS: A minority of female trainees takes time off or reduces their clinical duties for pregnancy or postpartum health needs. National parental leave policies are insufficient without complementary program-level strategies that support schedule adjustments for pregnant trainees without engendering a sense of resentment or guilt for doing so. Surgical program leaders should initiate open dialogue, proactively offer clinical duty reductions, and ensure time and space for lactation needs to safeguard maternal-fetal health and improve the working environment for pregnant residents.

Postpartum Depression in Surgeons and Workplace Support for Obstetric and Neonatal Complication: Results of a National Study of US Surgeons.

BACKGROUND: Postpartum depression has well-established long-term adverse effects on maternal and infant health. Surgeons with rigorous operative schedules are at higher risk of obstetric complications, but they rarely reduce their workload during pregnancy. We evaluated whether lack of workplace support for work reductions during difficult pregnancies or after neonatal complications is associated with surgeon postpartum depression. STUDY DESIGN: An electronic survey was sent to practicing and resident surgeons of both sexes in the US. Female surgeons who had at least one live birth were included. Lack of workplace support was defined as: (1) disagreeing that colleagues/leadership were supportive of obstetric-mandated bedrest or time off to care for an infant in the neonatal intensive care unit; (2) feeling unable to reduce clinical duties during pregnancy despite health concerns or to care for an infant in the neonatal intensive care unit. Multivariate logistic regression was used to determine the association of lack of workplace support with postpartum depression. RESULTS: Six hundred ninety-two surgeons were included. The 441 (63.7%) respondents who perceived a lack of workplace support had a higher risk of postpartum depression than those who did not perceive a lack of workplace support (odds ratio 2.21, 95% CI 1.09 to 4.46), controlling for age, race, career stage, and pregnancy/neonatal complications. Of the surgeons with obstetric-related work restrictions, 22.6% experienced loss of income and 38.5% reported >$50,000 loss. CONCLUSION: Lack of workplace support for surgeons with obstetric or neonatal health concerns is associated with a higher risk of postpartum depression. Institutional policies must address the needs of surgeons facing difficult pregnancies to improve mental health outcomes and promote career longevity.

Current understanding of Hirschsprung-associated enterocolitis: Pathogenesis, diagnosis and treatment.

Hirschsprung-associated enterocolitis (HAEC) was described in 1886 by Harald Hirschsprung and is a potentially deadly complication of Hirschsprung Disease. HAEC is classically characterized by abdominal distension, fever, and diarrhea, although there can be a variety of other associated symptoms, including colicky abdominal pain, lethargy, and the passage of blood-stained stools. HAEC occurs both pre-operatively and post-operatively, is the presenting symptom of HSCR in up to 25% of infants and varies in overall incidence from 20 to 60%. This article reviews our current understanding of HAEC pathogenesis, diagnosis, and treatment with discussion of areas of ongoing research, controversy, and future investigation.

Association between COVID-19 related elective surgery cancellations and pediatric inguinal hernia complications: A nationwide multicenter cohort study.

BACKGROUND: Optimal inguinal hernia repair timing remains controversial. It remains unclear how COVID-19 related elective surgery cancellations impacted timing of inguinal hernia repair and whether any delays led to complications. This study aims to determine whether elective surgery cancellations are safe in pediatric inguinal hernia. METHODS: This multicenter retrospective cohort study at 14 children's hospitals included patients ≤18 years who underwent inguinal hernia repair between September 13, 2019, through September 13, 2020. Patients were categorized by whether their inguinal hernia repair occurred before or after their hospital's COVID-19 elective surgery cancellation date. Incarceration and emergency department encounters were compared between pre and postcancellation. RESULTS: Of 1,404 patients, 604 (43.0%) underwent inguinal hernia repair during the postcancellation period, 92 (6.6%) experienced incarceration, and 213 (15.2%) had an emergency department encounter. The postcancellation period was not associated with incarceration (odds ratio 1.54; 95% confidence interval 0.88-2.71; P = .13) or emergency department encounters (odds ratio 1.53; 95% confidence interval 0.94-2.48; P = .09) despite longer median times to inguinal hernia repair (precancellation 29 days [interquartile range 13-55 days] versus postcancellation 31 days [interquartile range 14-73 days], P = .01). Infants were more likely to have the emergency department be their index presentation in the postcancellation period (odds ratio 1.69; 95% confidence interval 1.24-2.31; P < .01). CONCLUSION: Overall, COVID-19 elective surgery cancellations do not appear to increase the likelihood of incarceration or emergency department encounters despite delays in inguinal hernia repair, suggesting that cancellations are safe in children with inguinal hernia. Assessment of elective surgery cancellation safety has important implications for health policy.

Lack of Workplace Support for Obstetric Health Concerns is Associated With Major Pregnancy Complications: A National Study of US Female Surgeons.

OBJECTIVE: We sought to assess whether lack of workplace support for clinical work reductions during pregnancy was associated with major pregnancy complications. BACKGROUND: Surgeons are at high risk of major pregnancy complications. Although rigorous operative schedules pose increased risk, few reduce their clinical duties during pregnancy. METHODS: An electronic survey was distributed to US surgeons who had at least 1 live birth. Lack of workplace support was defined as: (1) desiring but feeling unable to reduce clinical duties during pregnancy due to failure of the workplace/training program to accommodate and/or concerns about financial penalties, burden on colleagues, requirement to make up missed call, being perceived as weak; (2) disagreeing colleagues and/or leadership were supportive of obstetrician-prescribed bedrest. Multivariate logistic regression determined the association between lack of workplace support and major pregnancy complications. RESULTS: Of 671 surgeons, 437 (65.13%) reported lack of workplace support during pregnancy and 302 (45.01%) experienced major pregnancy complications. Surgeons without workplace support were at higher risk of major pregnancy complications than those who had workplace support (odds ratio: 2.44; 95% confidence interval: 1.58-3.75). Bedrest was prescribed to 110/671 (16.39%) surgeons, 38 (34.55%) of whom disagreed that colleagues and/or leadership were supportive. Of the remaining surgeons, 417/560 (74.5%) desired work reductions but were deterred by lack of workplace support. CONCLUSIONS: Lack of workplace support for reduction in clinical duties is associated with adverse obstetric outcomes for surgeons. This is a modifiable workplace obstacle that deters surgeons from acting to optimize their infant's and their own health. To ensure the health of expectant surgeons, departmental policies should support reduction of clinical workload in an equitable manner without creating financial penalties, requiring payback for missed call duties, or overburdening colleagues.
