Laparoscopy is commonplace in pediatric surgery. Abdominal access via the umbilicus may present a unique challenge in neonates and young infants predisposing them to complications.
We hypothesized ...that these complications may occur more than described in the literature.
Members of the American Pediatric Surgical Association (APSA) were anonymously surveyed in February of 2018 via REDCap™ regarding technique of umbilical access in infants less than 3 months of age and complications experienced during umbilical access. Approval was obtained from the IRB and the APSA Outcomes and Evidence-based Practice Committee.
The response rate was 31.3% (329/1050). 62.3% of respondents performed 21 or greater neonatal laparoscopic procedures annually. 34 of 322 respondents reported a direct complication from umbilical access for laparoscopy in this age group (10.6%). Surgeons described 37 specific cases with complications related to umbilical access, with laparoscopic pyloromyotomy making up 47.2% (17/36). CO2 embolism was the most common complication; 15.4% of surgeons reported not knowing about the possibility of CO2 embolism. 41% of surgeons confirm intraabdominal placement of the umbilical trocar prior to insufflation. There was no association between any complication and where the umbilical trocar was placed (above/below/through umbilicus) or placement technique in patients with no umbilical cord stump. There may be an association between complication and where the umbilicus is entered in patients with an umbilical cord stump still in place (p = 0.013).
Umbilical access for laparoscopy in neonates and infants less than 3 months of age can present a unique challenge and result in significant complications. All techniques and methods had complications. Surgeons should be aware of these risks and be prepared to manage them emergently if they arise.

IMPORTANCE: Nonoperative management with antibiotics alone has the potential to treat uncomplicated pediatric appendicitis with fewer disability days than surgery. OBJECTIVE: To determine the success ...rate of nonoperative management and compare differences in treatment-related disability, satisfaction, health-related quality of life, and complications between nonoperative management and surgery in children with uncomplicated appendicitis. DESIGN, SETTING, AND PARTICIPANTS: Multi-institutional nonrandomized controlled intervention study of 1068 children aged 7 through 17 years with uncomplicated appendicitis treated at 10 tertiary children’s hospitals across 7 US states between May 2015 and October 2018 with 1-year follow-up through October 2019. Of the 1209 eligible patients approached, 1068 enrolled in the study. INTERVENTIONS: Patient and family selection of nonoperative management with antibiotics alone (nonoperative group, n = 370) or urgent (≤12 hours of admission) laparoscopic appendectomy (surgery group, n = 698). MAIN OUTCOMES AND MEASURES: The 2 primary outcomes assessed at 1 year were disability days, defined as the total number of days the child was not able to participate in all of his/her normal activities secondary to appendicitis-related care (expected difference, 5 days), and success rate of nonoperative management, defined as the proportion of patients initially managed nonoperatively who did not undergo appendectomy by 1 year (lowest acceptable success rate, ≥70%). Inverse probability of treatment weighting (IPTW) was used to adjust for differences between treatment groups for all outcome assessments. RESULTS: Among 1068 patients who were enrolled (median age, 12.4 years; 38% girls), 370 (35%) chose nonoperative management and 698 (65%) chose surgery. A total of 806 (75%) had complete follow-up: 284 (77%) in the nonoperative group; 522 (75%) in the surgery group. Patients in the nonoperative group were more often younger (median age, 12.3 years vs 12.5 years), Black (9.6% vs 4.9%) or other race (14.6% vs 8.7%), had caregivers with a bachelor’s degree (29.8% vs 23.5%), and underwent diagnostic ultrasound (79.7% vs 74.5%). After IPTW, the success rate of nonoperative management at 1 year was 67.1% (96% CI, 61.5%-72.31%; P = .86). Nonoperative management was associated with significantly fewer patient disability days at 1 year than did surgery (adjusted mean, 6.6 vs 10.9 days; mean difference, −4.3 days (99% CI, −6.17 to −2.43; P < .001). Of 16 other prespecified secondary end points, 10 showed no significant difference. CONCLUSION AND RELEVANCE: Among children with uncomplicated appendicitis, an initial nonoperative management strategy with antibiotics alone had a success rate of 67.1% and, compared with urgent surgery, was associated with statistically significantly fewer disability days at 1 year. However, there was substantial loss to follow-up, the comparison with the prespecified threshold for an acceptable success rate of nonoperative management was not statistically significant, and the hypothesized difference in disability days was not met.

Several studies have evaluated differences in firearm injury patterns among children based on regionalization. However, many of these studies exclude patients who die before arriving at a trauma ...center. We therefore hypothesize that important population-based differences in pediatric firearm injuries may be uncovered with the inclusion of both prehospital firearm mortalities and patients treated at a tertiary children's hospital.
Patients less than 15 y of age who sustained a firearms-related injury/death between the years 2012 and 2018 were identified in: (1) death certificates from the Office of Vital Statistics State of Indiana and (2) Riley Hospital for Children at Indiana University Health Trauma Registry. Counties of injury were classified as either urban, midsized, or rural based on the National Center for Health Statistic's population data. Significant variables in univariate analysis were then assessed using multivariate logistic regression models.
A total of 222 patients were identified. Median age of firearm injury survivors was 13 (interquartile range 7-14), while the median age of nonsurvivors was 14 (interquartile range 11-15), P = 0.040. The proportion of suicide was significantly higher in rural counties (P < 0.001). When controlling for shooter intent, patients from a rural or midsized county had statistically significant higher odds of dying before reaching a hospital than their urban counterpart (rural odds ratio OR 5.67 95% confidence interval {CI} 2.23, 14.38; midsized OR 6.53 95% CI 2.43, 17.46; P < 0.001).
Important differences exist between pediatric firearm injuries based on where they occur. Public health initiatives aimed at reducing pediatric firearm injury and death should not exclude rural pediatrics patients.

Duodenal atresia (DA), a common cause of congenital duodenal obstruction, is associated with trisomy 21. The postoperative feeding issues are not well described in this population. We hypothesize ...that the combination of DA and trisomy 21 is associated with the need for postoperative enteral feeding access.
A retrospective cohort of patients between 2010 and 2017 with the diagnosis of DA or duodenal stenosis was identified. Relevant prenatal and postnatal clinical data were abstracted. Univariate analyses were performed.
Forty-three patients were identified. Nineteen patients (44%) were diagnosed with trisomy 21. Eight patients (25% with trisomy 21) had gastrostomy placed at the time of DA repair. In the remaining patients (n = 35), 40% ultimately had a gastrostomy button placed. The indications for placement included poor oral skills (n = 8), aspiration (n = 5), and failure to thrive (n = 1). All these patients had trisomy 21, resulting in 82.4% of trisomy 21 patients having a gastrostomy. There was a significant association between trisomy 21 and placement of a gastrostomy button both during index admission (P = 0.003) and lifetime (P < 0.001). All trisomy 21 patients with congenital heart disease (n = 9) had a gastrostomy placed versus only five of eight trisomy 21 patients (62.5%) without structural heart disease (P = 0.006).
Our data suggest that a correlation exists between trisomy 21, structural congenital heart anomalies, DA, and the eventual need for gastrostomy. These data should inform operative planning for this patient population.

We aim to evaluate recurrence rates of gallstone pancreatitis in children undergoing early vs interval cholecystectomy.
A multicenter, retrospective review of pediatric patients admitted with ...gallstone pancreatitis from 2010 through 2017 was performed. Children were evaluated based on timing of cholecystectomy. Early cholecystectomy was defined as surgery during the index admission, whereas the delayed group was defined as no surgery or surgery after discharge. Outcomes, recurrence rates, and complications were evaluated.
Of 246 patients from 6 centers with gallstone pancreatitis, 178 (72%) were female, with mean age 13.5 ± 3.2 years and a mean body mass index of 28.9 ± 15.2. Most (90%) patients were admitted with mild pancreatitis (Atlanta Classification). Early cholecystectomy was performed in 167 (68%) patients with no difference in early cholecystectomy rates across institutions. Delayed group patients weighed less (61 kg vs. 72 kg, p = 0.003) and were younger (12 vs. 14 years, p = 0.001) than those who underwent early cholecystectomy. However, there were no differences in clinical, radiological, or laboratory characteristics between groups. There were 4 (2%) episodes of postoperative recurrent pancreatitis in the early group compared with 22% in the delayed group. More importantly, when cholecystectomy was delayed more than 6 weeks from index discharge, recurrence approached 60%. There were no biliary complications in any group.
Cholecystectomy during the index admission for children with gallstone pancreatitis reduces recurrent pancreatitis. Recurrence proportionally increases with time when patients are treated with a delayed approach.
Background
The aim of this study was to elucidate the outcomes of percutaneous internal ring suture (PIRS) technique for inguinal hernia repair augmented with thermal peritoneal injury compared to ...open inguinal hernia repair (OHR) in a large population of contemporary pediatric patients. Thermal injury with PIRS has been shown to reduce recurrence in animal models and is increasingly being incorporated into clinical practice.
Methods
Retrospective review of all PIRS procedures and OHR between Jan-2017 to Sept-2018 was performed. Data regarding patient characteristics, characteristics of the hernia, operative details, postoperative complications, and recurrence were collected. Non-parametric tests were used and
p
< 0.05 was regarded as statistically significant. 1:1 Propensity score matching was performed using “nearest-score” technique. Matching was done based on age, sex, follow-up time, side of hernia, repair of contralateral hernia, and number of additional procedures.
Results
90 modified PIRS patients were matched to 90 OHRs. Patient demographics, hernia characteristics, and follow-up time were similar between the two groups after matching. There were no differences in recurrence rates (1 vs. 3 in OHR and PIRS, respectively,
p
= 0.6), complication rates (1 vs. 4 in OHR and PIRS, respectively,
p
= 0.4), and OR time 44.5 vs. 43 min in OHR and PIRS, respectively,
p
= 0.8. There were no intraoperative complications for either technique. For OHR, laparoscopic look was performed in 23%. When successful, it revealed a contralateral PPV (patent processus vaginalis-PPV) in 41% of cases (9.4% of all OHR), all of which were repaired. For the PIRS procedures, a contralateral PPV was found in 25.6%, all of which were repaired. In the unmatched population, OHR had a metachronous hernia rate of 1.8%, none of whom had the contralateral PPV repaired at the original procedure.
Conclusions
PIRS with peritoneal injury has comparable efficacy and good safety compared to OHR. Recurrence and complication rates should further improve with increasing experience. Future studies should elucidate long term outcomes.

Pectus excavatum and pectus carinatum are the most common chest wall deformities of childhood. Surgical repair can be complicated by post-operative analgesic challenges. Thoracic epidural analgesia, ...patient-controlled analgesia, and multimodal pain control are among the most common strategies. We sought to define the current utilization of intraoperative thoracic neurolysis, hypothesizing that this would minimize length of stay (LOS) and post-operative narcotic use with relatively higher proportion of non-narcotic post-operative analgesia.
We performed a retrospective review of the Pediatric Health Information System (PHIS) database between 2017 and 2020. We first identified patients who underwent a pectus repair via ICD-10-PCS codes. We used ICD-10-PCS codes 01580ZZ and 01584ZZ to identify those patients who underwent concomitant thoracic neurolysis. Statistical analyses were performed using R; p value less than 0.05 was considered significant.
We identified 2979 patients who underwent a pectus repair. 184 underwent a concomitant thoracic nerve destruction procedure (6.7%); 13 were performed in 2017 (2.01%), 76 in 2018 (10.7%), and 84 in 2019 (9.6%). LOS was shorter in those patients who underwent neurolysis (mean=2.55 vs 3.73 days, SD=1.33 vs 1.78 days, p<0.001). There were fewer post-operative ICU admissions in neurolysis patients (3/184 vs. 193/2795, p = 0.003). The cost of procedures that included a neurolysis were higher, though not significantly so (mean=$24,885.64 vs $22,200.59).
Thoracic neurolysis may be a useful analgesic strategy, expediating post-operative discharge and potentially obviating the need for intensive care. Further larger-scale prospective trials should be considered to further elucidate the role of this analgesia method.

Ammonites, as well as other fauna, were common in methane seeps of the Late Cretaceous Western Interior Seaway (WIS) of North America. Biogeochemical processes at the seeps, in particular the ...anaerobic oxidation of methane, produced a dissolved inorganic carbon reservoir with a low δ13C, manifested in the carbon isotope composition of the inorganic calcium carbonate concretions associated with the seeps and recorded in well-preserved shells of ammonites documented at the sites. Detailed sclerochronological sampling of six well-preserved specimens of Baculites compressus collected at seep sites in the Pierre Shale of South Dakota reveals three patterns that can be explained by reference to two specimens of the same species collected at age-equivalent non-seep sites. Three of the specimens exhibit uniformly low values of δ13C that are significantly different (unpaired t-test, p < .0001) from similarly sized specimens of the same species collected at age-equivalent non-seep sites, suggesting that these ammonites lived at the seeps during the time interval over which the shell was secreted (adult portion of the shell). Two of the specimens collected from a seep site exhibit values of δ13C consistent with early ontogeny at a non-seep site followed by later ontogeny at a seep site. The values of δ18O of all the specimens reveal water temperatures of 16 to 28 °C. One small juvenile (15 mm long) collected at a seep site exhibits higher values of δ13C consistent with a non-seep environment, but values of δ18O that indicate very warm or slightly brackish water, suggesting that this animal lived in surface waters during its early ontogeny and died soon after arriving at the seep. Our results demonstrate that seep fluids affected the geochemistry of the water column above the seeps and that seeps provided habitats for ammonites in the WIS. Thus, although ammonites were mobile animals, they probably exploited a low-energy life style, remaining at the same site for extended periods of time.
Available evidence supports ovary-sparing surgery for benign ovarian neoplasms; however, preoperative risk stratification of pediatric ovarian masses can be difficult. Our objective of this study was ...to characterize the surgical management of pediatric ovarian neoplasms across 10 children's hospitals and to identify factors that could potentially aid in the preoperative risk stratification of these lesions.
A retrospective review of girls and women aged 2 to 21 years who underwent surgery for an ovarian neoplasm between 2010 and 2016 at 10 children's hospitals was performed. Multivariable logistic regression was used to examine the relationships between the preoperative cohort characteristics, procedure performed, and risk of malignancy.
Among 819 girls and women undergoing surgery for an ovarian neoplasm, malignant lesions were identified in 11%. The overall oophorectomy rate for benign disease was 33% (range: 15%-49%) across institutions. Oophorectomy for benign lesions was independently associated with provider specialty (
= .002: adult gynecologist, 45%; pediatric surgeon, 32%; pediatric gynecologist, 18%), premenarchal status (
= .02), preoperative suspicion for malignancy (
< .0001), larger lesion size (
< .0001), and presence of solid components (
< .0001). Preoperative findings independently associated with malignancy included increasing size (
< .0001), solid components (
= .003), and age (
< .0001).
The rate of oophorectomy for benign ovarian disease remains high within the pediatric population. Identification of factors associated with the choice of procedure and the risk of malignancy may allow for improved preoperative risk stratification and fewer unnecessary oophorectomies. These results have been used to develop and validate a multidisciplinary preoperative risk stratification algorithm that is currently being studied prospectively across 10 institutions.
