INTRODUCTION/BACKGROUND:Traumatic brain injury (TBI) is the leading cause of pediatric disability. Most pediatric TBIs are mild but can result in long-term cognitive and functional impairments. Outpatient follow-up is essential to detect post-concussive symptoms and aid recovery. METHODS:All patients 3-18 years of age with positive TBI findings on CT or MRI from 2018-2024 were retrospectively reviewed. Follow-up was defined as an appointment with neurology, neuropsychology, neurosurgery, or physical medicine and rehabilitation within three months of discharge. Analyses were performed with appropriate Chi-squared, Fisher's exact, Mann-Whitney U, or t-tests. RESULTS:Fifty-seven patients (41 male, mean age 11.4 years) were identified, with mild TBIs (GCS 13-15) comprising 41/57 (71.9%). Four patients (7.0%) died from their injury. Of 53 surviving patients, 20 (37.7%) had follow-up appointments scheduled for them at discharge, seven (13.2%) were given a specific date and contact number, 17 (32.1%) received service referrals without a specific date, and eight (15.1%) received nonspecific directions or were directed only to follow-up with non-neuroscience services. Within three months, 32 (60.4%) patients followed up, though only 22/53 (41.5%) patients saw a non-surgical neuroscience discipline. Patients who followed up were more likely to have undergone neurosurgery (p = 0.007) or any surgical procedure at all (p = 0.007). They were also more likely to have a shorter hospital length of stay (p = 0.021). Discharge instruction type was significantly associated with follow-up (p = 0.0013); 62.5% of patients who followed up had an appointment scheduled for them or were given a specific date versus 33.4% of patients who did not follow-up. Conversely, 38.1% of patients without follow-up received nonspecific instructions or were told to follow-up with non-neuroscience specialties. This finding remained significant when excluding patients with severe TBI. Follow-up had no significant associations with demographics, injury severity, or insurance type. CONCLUSION/CONCLUSIONS:Patient-centered discharge instructions with detailed service referrals increase access to critical follow-up care. Children with TBIs should have follow-up care arranged regardless of injury severity. Larger multicenter studies are needed to validate these findings.

Extracorporeal membrane oxygenation (ECMO) to support neonates and children with cardiopulmonary failure was first described in the 1970s, since which time its use has expanded to an increasingly complex and heterogenous pediatric population. Despite preserved survival outcomes, complications of ECMO use, including iatrogenic vascular injury, are common. Here, we provide a brief overview of the epidemiology of pediatric ECMO and associated vascular complications; describe common peripheral cannulation equipment and techniques, trends in cannulation and decannulation strategies, and respective incidence of vascular complications; and review existing evidence for best practices in cannula site selection, cannulation technique, decannulation strategies, and management of vascular complications, with the goal of providing a comprehensive review for interventionalists involved in the care of pediatric ECMO patients. Areas of wide practice variation in vessel management-application of vessel-sparing cervical venoarterial cannulation, the use of distal perfusion catheters in femoral arterial cannulation, and best practices for percutaneous single-lumen venovenous cannulation, as examples-areas of focus for future research, and the potential role of vascular surgeons and other subspecialty proceduralists in the care of pediatric ECMO patients are highlighted.

PURPOSE/OBJECTIVE:The premature infant brain may be particularly vulnerable to anesthesia effects, but there is conflicting evidence on the association between anesthesia exposure and developmental outcomes. Twin studies can control for confounding factors. A twin cohort of premature twins provides internal control of difficulty to measure confounders and delivers added power to a study examining the effects of anesthesia on neurodevelopmental outcomes. METHODS:We conducted a retrospective cohort study of sets of premature twins and multiples born at an academic medical center, in which 1 member of the set was exposed to general anesthesia. The primary outcome was the composite scores using Bayley Scale of Infant and Toddler Development III performed at age 6 months to 18 months. Unpaired and paired analyses were performed with linear regression models, Wilcoxon signed rank test, and Mann-Whitney U test. RESULTS:We identified 81 children born at less than 32 weeks gestation within 39 sets of twins and 1 set of triplets for a total of 18 paired observations. All of the exposed infants had a single exposure to general anesthesia. There was no significant association between anesthesia exposure and a diagnosis of developmental delay (OR = 0.8; 95% confidence interval, 0.2-3.2; p = 0.99). Regression models demonstrated no association between anesthesia exposure and cognitive (96.67 vs 97.50; p = 0.74), language (98.33 vs 98.61; p = 0.94), or motor (96.25 vs 96.44; p = 0.91) composite Bayley scores. There was no association between duration of anesthesia and the 3 composite Bayley scores ( p = 0.33; p = 0.40; p = 0.74). CONCLUSION/CONCLUSIONS:Using a premature twin cohort with discordant exposure to anesthesia, our data did not demonstrate any association between anesthesia exposure and developmental delay in this vulnerable population of premature infants.

Choledochal cysts are rare cystic dilations of the biliary tree that typically involve the extrahepatic bile duct and more infrequently, the intrahepatic bile ducts. Todani's classification of choledochal cysts is the most referenced system in which five types of choledochal cysts are described. Several new variants have been reported including dilations of the cystic duct and a double common bile duct. We describe a never reported variant involving dilation of the common bile duct, dilation of the cystic duct and an accessory right hepatic duct.

BACKGROUND:Published data demonstrate that management of uncomplicated pediatric appendicitis with antibiotics-alone is safe and frequently successful. Randomized controlled trials (RCT) comparing antibiotics-alone to appendectomy are lacking, alongside insight into drivers of failure. We sought to validate the antibiotics-alone approach and identify barriers to success using an RCT design. METHODS:Patients aged 6-17 years with uncomplicated appendicitis were randomized to appendectomy or intravenous piperacillin/tazobactam for 24-48 h followed by 10 days of oral ciprofloxacin/metronidazole. Enrollment required symptoms <48 h, WBC<18, appendiceal diameter <11 mm, and radiographic absence of perforation. Lack of clinical improvement or persistently elevated WBC resulted in appendectomy. Primary outcomes were 1-year success rate of antibiotics-alone and quality-of-life measures. RESULTS:Among 39 children enrolled over 31 months, 20 were randomized to antibiotics-alone and 19 to surgery. At 1 year, 6 nonoperative patients underwent appendectomy (70% success). Four cases were not true antibiotic failures but instead reflected "pragmatic" challenges to executing nonoperative algorithms. Only 2 cases represented recurrent/refractory appendicitis, suggesting a 90% adjusted 1-year success rate. Parental PedsQL™ scores were similar between treatment cohorts (91.3 vs 90.2, P = 0.32). Children treated with antibiotics-alone had faster return to activity (2.0 vs 12 days, P = 0.001) and fewer parental missed work days (0.0 vs 2.5, P = 0.03). CONCLUSIONS:These data corroborate findings from non-randomized studies suggesting 70-90% of uncomplicated pediatric appendicitis can be treated with antibiotics-alone, with fewer disability days. Failures appear multifactorial, often reflecting practical hurdles and not antibiotic limitations. As surgeons consider nonoperative protocols for uncomplicated appendicitis, these data further inform the variability of treatment success. LEVEL OF EVIDENCE/METHODS:1; randomized controlled trial.

OBJECTIVE:The aim of the study was to determine whether perforated appendicitis rates in children were influenced by the Coronavirus disease 2019 (COVID-19) surge. BACKGROUND:Disruption of care pathways during a public health crisis may prevent children from obtaining prompt assessment for surgical conditions. Progression of appendicitis to perforation is influenced by timeliness of presentation. In the context of state-mandated controls and public wariness of hospitals, we investigated the impact of the COVID-19 outbreak on perforated appendicitis in children. STUDY DESIGN/METHODS:We conducted an analysis of all children presenting to 3 hospital sites with acute appendicitis between March 1 and May 7, 2020, corresponding with the peak COVID-19 outbreak in the New York City region. Control variables were collected from the same institutions for the preceding 5 years. The primary outcome measure was appendiceal perforation. RESULTS:Fifty-five children presented with acute appendicitis over 10 weeks. Compared to a 5-year control cohort of 1291 patients, we observed a higher perforation rate (45% vs 27%, odds ratio 2.23, 95% confidence interval 1.29-3.85, P = 0.005) and longer mean duration of symptoms in children with perforations (71 ± 39 vs 47 ± 27 h, P = 0.001) during the COVID-19 period. There were no differences in perforation rates (55% vs 59%, P = 0.99) or median length of stay (1.0 vs 3.0 days, P = 0.58) among children screening positive or negative for SARS-CoV-2. CONCLUSIONS:Children in the epicenter of the COVID-19 outbreak demonstrated higher rates of perforated appendicitis compared to historical controls. Preoperative detection of SARS-CoV-2 was not associated with inferior outcomes. Although children likely avoid much of the morbidity directly linked to COVID-19, disruption to local healthcare delivery systems may negatively impact other aspects of pediatric surgical disease.
