RESUMEN
OBJECTIVE: To determine whether hospital- and surgeon-level operative volumes are associated with differences in postoperative outcomes among infants undergoing elective lung surgery for a congenital lung malformation (CLM). SUMMARY BACKGROUND DATA: Infant lung surgery is a relatively uncommon procedure performed by pediatric surgeons nationwide. The relationship between surgical volume and postoperative outcomes remains unknown. METHODS: A retrospective cohort study of asymptomatic infants who underwent elective lung resection of a CLM was conducted using the Pediatric Health Information System database (2016-2020). Multivariable linear and poisson regressions were performed based on annual lung resection tertiles. RESULTS: There were 1420 infants managed by 48 hospitals and 309 primary surgeons. Institutions that performed seven or fewer CLM resections per year (56%) were associated with significantly higher postoperative complication rates compared to medium- and high-volume hospitals (low: 134 [34%], medium: 110 [21%], high: 144 [29%]; P<0.001). Surgeons who performed one or fewer CLM resections per year (82%) were associated with significantly higher complication rates compared to medium- and high-volume surgeons (low: 171 [31%], medium: 75 [26%], high: 119 [24%]; P=0.02). Multivariable analyses confirmed that low-volume hospitals were associated with higher complications (OR 1.81, CI 1.38-2.37; P<0.001), and low-volume surgeons had an increased risk of complications (overall: OR 1.37, CI 1.01-1.84; P=0.04). CONCLUSIONS: In this cohort study of infants undergoing elective lung resection for a CLM, lower volume providers were associated with higher postoperative patient morbidity. These findings represent an opportunity to inform quality improvement initiatives on pediatric lung resection and the debate on surgical subspecialization for this unique patient population.
RESUMEN
OBJECTIVE: To compare disease severity and mortality differences between female and male patients with congenital diaphragmatic hernia (CDH). STUDY DESIGN: We queried the CDH Study Group (CDHSG) database for CDH neonates managed between 2007 and 2018. Female and males were compared in statistical analyses using t tests, χ² tests, and Cox regression, as appropriate (P ≤ .05). RESULTS: There were 7288 CDH patients, of which 3048 (41.8%) were female. Females weighed less on average at birth than males (2.84 kg vs 2.97 kg, P < .001) despite comparable gestational age. Females had similar rates of extracorporeal life support (ECLS) utilization (27.8% vs 27.3%, P = .65). Although both cohorts had equivalent defect size and rates of patch repair, female patients had increased rates of intrathoracic liver herniation (49.2% vs 45.9%, P = .01) and pulmonary hypertension (PH) (86.6% vs 81.1%, P < .001). Females had lower survival rates at 30-days (77.3% vs 80.1%, P = .003) and overall lower survival to discharge (70.2% vs 74.2%, P < .001). Subgroup analysis revealed that increased mortality was significant among those who underwent repair but were never supported on ECLS (P = .005). On Cox regression analysis, female sex was independently associated with mortality (adjusted hazard ratio 1.32, P = .02). CONCLUSION: After controlling for the established prenatal and postnatal predictors of mortality, female sex remains independently associated with a higher risk of mortality in CDH. Further study into the underlying causes for sex-specific disparities in CDH outcomes is warranted.

INTRODUCTION: The value of chest computed tomography (CT) in pediatric primary spontaneous pneumothorax (PSP) remains controversial. This study sought to evaluate the utility of CT scans in a contemporary cohort of children with PSP. MATERIALS AND METHODS: An institutional review board approval was obtained for a retrospective review of all children (aged ≤18 y) who underwent video-assisted thoracoscopic surgery (VATS) for PSP between 2009 and 2019 at a university-affiliated pediatric hospital. Preoperative CT scans were evaluated for diagnostic accuracy of the CT of bleb disease. RESULTS: Thirty nine patients underwent VATS procedures for PSP, 34 (87%) of the patients were noted to have blebs. Twenty eight (72%) patients received preoperative CT scans with a 5.5:1 male to female ratio. On CT, 17 (61%) were diagnosed with blebs and all had blebs intraoperatively. CT did not identify disease in 11 patients, but seven had blebs intraoperatively. The positive and negative predictive values of preoperative CT for detecting ipsilateral bleb disease were 100% and 36%, respectively, with a sensitivity of 71%. Eleven patients had a contralateral disease on CT (39%). Five received elective contralateral VATS and three developed spontaneous PSP, with intraoperative blebs in all eight patients. Three never developed contralateral PSP. Six (21%) patients with no contralateral disease on CT developed spontaneous PSP with intraoperative blebs. CONCLUSIONS: The decision to operate for PSP should be made based on clinical findings rather than on the presence or absence of blebs identified by CT.

INTRODUCTION: Laparoscopic repair of duodenal atresia in neonates has gained popularity among some pediatric surgeons. Single-center studies suggest comparable short-term outcomes to open surgery. The purpose of this study was to utilize a large, multi-institutional pediatric dataset to examine 30-day post-operative outcomes by operative approach for newborns who underwent duodenal atresia repairs. METHODS: We identified neonates aged ≤1 wk in the 2016-2018 National Surgical Quality Improvement Program-Pediatric -database that underwent a laparoscopic or open repair for duodenal atresia. Preoperative characteristics were compared between operative approaches. Postoperative complications, operative time, postoperative length of stay (LOS), and supplemental nutrition at discharge were assessed using multivariate regressions. RESULTS: There were 267 neonates who met inclusion criteria. There were 233 (87%) infants who underwent open repairs and 34 (13%) who underwent laparoscopic repairs. Ten (29%) children who had laparoscopy were converted to open. After adjusting for confounding, laparoscopy was associated with an increase in operative time by 65 min (95% confidence interval 45-87 min, P < 0.001) but a five-day shorter LOS (95% confidence interval -9 to -2, P = 0.006) when compared to laparotomy. There were no significant differences in postoperative complications or supplemental nutrition at discharge. CONCLUSIONS: Our findings suggest that laparoscopic repairs of duodenal atresia are associated with shorter postoperative LOS but longer operative times when compared to open repairs. Although the conversion rate to laparotomy remained relatively high, the laparoscopic approach was associated with comparable 30-day postoperative outcomes.

OBJECTIVES: Observational data to support delaying elective pediatric thoracic surgery during peak respiratory viral illness season is lacking. This study evaluated whether lung surgery during peak viral season is associated with differences in postoperative outcomes and resource utilization. METHODS: A retrospective observational cohort study was performed using the Pediatric Health Information System (PHIS). Patients with a congenital lung malformation (CLM) who underwent elective lung resection between 1 January 2016 and 29 February 2020 were included. Respiratory syncytial virus (RSV) incidence was used as a proxy for respiratory viral illness circulation. Monthly hospital-specific RSV incidence was calculated from PHIS data, and peak RSV season was defined by Centers for Disease Control data. Multivariable regression models were built to identify predictors of postoperative mechanical ventilation, which was the main outcome measure, as well as secondary outcomes including 30-day readmission after lung resection, postoperative length of stay (LOS) and hospital billing charges. RESULTS: Of 1542 CLM patients identified, 344 (22.3%) underwent lung resection during peak RSV season. 38% fewer operations were performed per month during peak RSV season than during off-peak months (p < .001). Children who underwent surgery during peak RSV season did not differ from the off-peak group in terms of age at operation, race, or comorbid conditions (i.e., congenital heart disease, newborn respiratory distress, and preoperative pneumonia). There was no association between hospital-specific RSV incidence at the time of surgery and postoperative mechanical ventilation, postoperative LOS, 30-day readmission rate or hospital billing charges. DISCUSSION: Performing elective lung surgery in children with CLMs during peak viral season is not associated with adverse surgical outcomes or increased utilization of healthcare resources.

BACKGROUND: Tunneled central venous catheters (CVCs) are the cornerstone of modern oncologic practice. Establishing best practices for catheter management in children with cancer is essential to optimize care, but few guidelines exist to guide placement and management. OBJECTIVES: To address four questions: 1) Does catheter composition influence the incidence of complications; 2) Is there a platelet count below which catheter placement poses an increased risk of complications; 3) Is there an absolute neutrophil count (ANC) below which catheter placement poses an increased risk of complications; and 4) Are there best practices for the management of a central line associated bloodstream infection (CLABSI)? METHODS: Data Sources: English language articles in Ovid Medline, PubMed, Embase, Web of Science, and Cochrane Databases. STUDY SELECTION: Independently performed by 2 reviewers, disagreements resolved by a third reviewer. DATA EXTRACTION: Performed by 4 reviewers on forms designed by consensus, quality assessed by GRADE methodology. RESULTS: Data were extracted from 110 manuscripts. There was no significant difference in fracture rate, venous thrombosis, catheter occlusion or infection by catheter composition. Thrombocytopenia with minimum thresholds of 30,000-50,000 platelets/mcl was not associated with major hematoma. Limited evidence suggests a platelet count <30,000/mcL was associated with small increased risk of hematoma. While few studies found a significant increase in CLABSI in CVCs placed in neutropenic patients with ANC<500Kcells/dl, meta-analysis suggests a small increase in this population. Catheter removal remains recommended in complicated or persistent infections. Limited evidence supports antibiotic, ethanol, or hydrochloric lock therapy in definitive catheter salvage. No high-quality data were available to answer any of the proposed questions. CONCLUSIONS: Although over 15,000 tunneled catheters are placed annually in North America into children with cancer, there is a paucity of evidence to guide practice, suggesting multiple opportunities to improve care. LEVEL OF EVIDENCE: III. This study was registered as PROSPERO 2019 CRD42019124077.

BACKGROUND: The purpose of this study was to assess diagnostic accuracy and neonatal outcomes in fetuses with a suspected proximal gastrointestinal obstruction (GIO). METHODS: After IRB approval, a retrospective chart review was conducted on prenatally suspected and/or postnatally confirmed cases of proximal GIO at a tertiary care facility (2012-2022). Maternal-fetal records were queried for presence of a double bubble ± polyhydramnios, and neonatal outcomes were assessed to calculate the diagnostic accuracy of fetal sonography. RESULTS: Among 56 confirmed cases, the median birthweight and gestational age at birth were 2550 g [interquartile range (IQR) 2028-3012] and 37 weeks (IQR 34-38), respectively. There was one (2%) false-positive and three (6%) false-negatives by ultrasound. Double bubble had a sensitivity, specificity, positive predictive value, and negative predictive value for proximal GIO of 85%, 98%, 98%, and 83%, respectively. Pathologies included 49 (88%) with duodenal obstruction/annular pancreas, three (5%) with malrotation, and three (5%) with jejunal atresia. The median postoperative length of stay was 27 days (IQR 19-42). Cardiac anomalies were associated with significantly higher complications (45% vs 17%, p = 0.030). CONCLUSIONS: In this contemporary series, fetal sonography has high diagnostic accuracy for detecting proximal gastrointestinal obstruction. These data are informative for pediatric surgeons in prenatal counseling and preoperative discussions with families. LEVEL OF EVIDENCE: Diagnostic Study, Level III.

BACKGROUND: This study aimed to evaluate the contemporary surgical management of long-gap esophageal atresia, a rare and challenging problem managed by pediatric general surgeons. METHODS: A retrospective review of the Pediatric Health Information System database for infants who underwent neonatal gastrostomy, followed by surgical reconstruction for long-gap esophageal atresia (2014-2021). Patients with birthweight less than 1.5 kg and those who received neonatal cardiac surgery were excluded. Outcomes were analyzed, including the need for further procedures, length of stay, and mortality. RESULTS: Of 1,346 infants who underwent repair across 47 major children's hospitals, 100 (7%) met the inclusion criteria for long-gap esophageal atresia. Cardiac anomalies were identified in 43% of patients. The median age at repair was 87 days (interquartile range, 62-133). Ten percent of patients had a planned or unplanned reoperation ≤30 days after index surgery, and 4% underwent reoperation at >30 days. The median time to reoperation was 9 days (interquartile range, 7-60). Mortality during index admission was 5%, and the median hospital length of stay was 143 days (interquartile range, 101-192). Length of stay was significantly longer in patients with cardiac anomalies (cardiac: 179 days, non-cardiac: 125 days; P < .001), and 52% of patients required at least 1 postoperative dilation. The median time to the first dilation was 70 days (interquartile range, 42-173). CONCLUSION: This large multicenter study highlights the challenges of infants with long-gap esophageal atresia but suggests a high rate of successful delayed primary reconstruction. Hospitalizations are prolonged, and anastomotic stricture rates remain high. These data are useful for pediatric surgeons in counseling families on surgical repair strategy, timing, and postoperative outcomes.

BACKGROUND: Although fetoscopic endoluminal tracheal occlusion (FETO) was recently shown to improve survival in a multicenter, randomized trial of severe congenital diaphragmatic hernia (CDH), morbidity outcomes remain essentially unknown. The purpose of this study was to assess long-term outcomes in children with severe CDH who underwent FETO. METHODS: We conducted a prospective study of severe CDH patients undergoing FETO at an experienced North American center from 2015-2021 (NCT02710968). This group was compared to a cohort of non-FETO CDH patients with severe disease as defined by liver herniation, large defect size, and/or ECMO use. Clinical data were collected through a multidisciplinary CDH clinic. Statistics were performed with t-tests and Chi-squared analyses (p≤0.05). RESULTS: There were 18 FETO and 17 non-FETO patients. ECMO utilization was 56% in the FETO cohort. Despite significantly lower median observed/expected lung-to-head ratio (O/E LHR) in the FETO group, [FETO: 23% (IQR:18-25) vs. non-FETO: 36% (IQR: 28-41), p<0.001], there were comparable survival rates at discharge (FETO: 78% vs. non-FETO: 59%, p = 0.23) and at 5-years (FETO: 67% vs. non-FETO: 59%, p = 0.53) between the two cohorts. At a median follow up of 5.8 years, metrics of pulmonary hypertension, pulmonary morbidity, and gastroesophageal reflux disease improved among patients after FETO. However, most FETO patients remained on bronchodilators/inhaled corticosteroids (58%) and were feeding tube dependent (67%). CONCLUSIONS: These North American data show that prenatal tracheal occlusion, in conjunction with a long-term multidisciplinary CDH clinic, is associated with acceptable long-term survival and morbidity in children after FETO. LEVEL OF EVIDENCE: Level III.

BACKGROUND: Neonatal resection is the mainstay treatment of children presenting with symptomatic congenital lung malformation (CLM) at birth. The objective of this study was to evaluate risk factors for increased morbidity and mortality after neonatal CLM resection using a large multicenter database. STUDY DESIGN: Retrospective review of the Pediatric Health Information System database was performed. Children with a symptomatic CLM managed by lung resection before 30 days of age were included (2016 to 2021). Primary outcomes measures were postoperative respiratory complication and any complication, including death. RESULTS: Of 1,791 CLM patients identified, 256 (14%) underwent neonatal resection for symptomatic disease. Pathology included 123 (48%) congenital pulmonary airway malformation, 24 (10%) bronchopulmonary sequestration, 5 (2%) congenital lobar emphysema, 16 (6%) hybrid, and 88 (34%) unclassified lesion. Preoperative mechanical ventilation and extracorporeal membrane oxygenation (ECMO) were employed in 149 (58.2%) and 17 (6.7%) of cases, respectively. The median age at resection was 6.5 days (interquartile range 2 to 23). Postoperatively, 25 (10%) required mechanical ventilation for 48 hours or more, 3 (1%) continued ECMO, and 3 (1%) required ECMO rescue. The overall respiratory complication rate was 34% (87), rate of any complication was 51% (130), median postoperative length of stay was 20 days (interquartile range 9 to 52), and mortality rate was 14.5% (37). Birthweight was inversely correlated with complication risk (incidence rate ratio 0.55, 95% CI 0.36 to 0.83, p = 0.006). Cardiac structural anomaly was associated with a 21-day longer postoperative length of stay (95% CI 6 to 35, p = 0.006) and 2.2 times increased risk of any complication (95% CI 1.18 to 4.02, p = 0.014). CONCLUSIONS: In this large multicenter study, ECMO use and mortality are relatively uncommon among neonates undergoing lung resection for a symptomatic CLM. However, postoperative morbidity remains high, particularly in those with cardiac structural disease.

BACKGROUND: Several studies have shown that the congenital pulmonary airway malformation volume ratio is a useful prognosticator of neonatal outcome in prenatally diagnosed lung lesions. However, there remains a lack of consensus on which congenital pulmonary airway malformation volume ratio values have the best predictive value because of operator dependence, inherent changes in lung lesion size throughout gestation, and the widespread use of maternal steroids. OBJECTIVE: This study sought to determine the association between serial congenital pulmonary airway malformation volume ratio measurements and neonatal outcomes among fetuses with lung malformations. STUDY DESIGN: This was a retrospective cohort study of fetuses with a prenatally diagnosed lung malformation managed at 2 major fetal centers from January 2010 to December 2021. Prenatal variables, including prospectively measured congenital pulmonary airway malformation volume ratio measurements (initial, maximum, and final), were analyzed. The results were correlated with 3 outcome measures, namely surgical resection before 30 days of life, a need for supplemental O2 at birth, and endotracheal intubation at birth. Statistical analyses were performed using receiver operating characteristic curve analyses, Welch 2 sample t tests, and multivariable logistic regressions (P<.05). RESULTS: There were 123 fetuses with isolated lung lesions identified. Eight (6.5%) had hydrops. The mean initial congenital pulmonary airway malformation volume ratio was 0.67±0.61 cm2 at 22.9±3.9 weeks' gestation. The mean maximum congenital pulmonary airway malformation volume ratio was 1.08 ± 0.94 cm2 at 27.0 ± 4.0 weeks' gestation. The mean final congenital pulmonary airway malformation volume ratio was 0.58±0.60 cm2 at 33.2±4.1 weeks' gestation. At a mean gestational age at delivery of 38.3±2.6 weeks, 15 (12.2%) underwent neonatal lung resection for symptomatic disease. In a multivariable regression, all 3 congenital pulmonary airway malformation volume ratio measurements showed a significant correlation with neonatal lung resection (P<.001). Optimal congenital pulmonary airway malformation volume ratio cutoffs were established based on an initial congenital pulmonary airway malformation volume ratio of ≥0.8 cm2, maximum congenital pulmonary airway malformation volume ratio of ≥1.5 cm2, and a final congenital pulmonary airway malformation volume ratio of ≥1.3 cm2 with associated areas under the curve of 0.89, 0.97, and 0.93, respectively. The final congenital pulmonary airway malformation volume ratio had the highest specificity for predicting surgical lung resection in the early postnatal period. CONCLUSION: Measuring congenital pulmonary airway malformation volume ratios throughout pregnancy in fetuses with pulmonary malformations has clinical value for prenatal counseling and planning care transition after delivery. Fetuses with a final congenital pulmonary airway malformation volume ratio of more than 1.3 cm2 are likely to require neonatal surgery and therefore should be delivered at tertiary care centers with a neonatal intensive care unit and pediatric surgical expertise.

BACKGROUND: Nephrogenic rests (NR) may represent precursor lesions for Wilms tumor (WT), but their clinical course is not fully understood and no guidelines for treatment exist. This study sought to evaluate the outcomes of pediatric patients with NRs related to traditional chemotherapy and surgery. METHODS: A PRISMA-P-compliant literature search was conducted in MEDLINE, Embase, CINAHL, Web of Science, COCHRANE, and SCOPUS from inception to June 2021. Clinical questions regarding the treatment of NRs, including chemotherapy and surgery, were developed in the population, intervention, comparison, and outcome format. RESULTS: Twenty-five studies including 1445 patients met inclusion criteria for evaluating chemotherapy compared to observation for NRs. Eighteen studies including 1392 patients met inclusion criteria for evaluating the role of surgery for NRs. Patients with isolated NRs who underwent observation progressed to WT 33% of the time; chemotherapy reduced the rate of WT to 3.9%. Observation of multiple NRs and diffuse hyperplastic perilobar nephroblastomatosis (DHPLN) led to progression to WT 50% and 100% of the time, respectively. Chemotherapy reduced the rate of WT to 34% for multiple NRs and 46% for DHPLN. Surgery for isolated NRs reduced the risk of WT development from 23.7% in patients with incomplete excision to 3.3% with complete excision; however, 96% of patients with incompletely excised NRs had bilateral disease. CONCLUSIONS: Observation with close surveillance for isolated NRs is safe. Treatment with chemotherapy is recommended for patients with multiple NRs and DHPLN. Surgical management of NRs should focus on renal function preservation. LEVEL OF EVIDENCE: Treatment study, Level III.
RESUMEN
Importance: There is some data to suggest that racial and ethnic minority infants with congenital diaphragmatic hernia (CDH) have poorer clinical outcomes. Objective: To determine what patient- and institutional-level factors are associated with racial and ethnic differences in CDH mortality. Design, Setting, and Participants: Multicenter cohort study of 49 US children's hospitals using the Pediatric Health Information System database from January 1, 2015, to December 31, 2020. Participants were patients with CDH admitted on day of life 0 who underwent surgical repair. Patient race and ethnicity were guardian-reported vs hospital assigned as Black, Hispanic (White or Black), or White. Data were analyzed from August 2021 to March 2022. Exposures: Patient race and ethnicity: (1) White vs Black and (2) White vs Hispanic; and institutional-level diversity (as defined by the percentage of Black and Hispanic patients with CDH at each hospital): (1) 30% or less, (2) 31% to 40%, and (3) more than 40%. Main Outcomes and Measures: The primary outcomes were in-hospital and 60-day mortality. The study hypothesized that hospitals managing a more racially and ethnically diverse population of patients with CDH would be associated with lower mortality among Black and Hispanic infants. Results: Among 1565 infants, 188 (12%), 306 (20%), and 1071 (68%) were Black, Hispanic, and White, respectively. Compared with White infants, Black infants had significantly lower gestational ages (mean [SD], White: 37.6 [2] weeks vs Black: 36.6 [3] weeks; difference, 1 week; 95% CI for difference, 0.6-1.4; P < .001), lower birthweights (White: 3.0 [1.0] kg vs Black: 2.7 [1.0] kg; difference, 0.3 kg; 95% CI for difference, 0.2-0.4; P < .001), and higher extracorporeal life support use (White: 316 patients [30%] vs Black: 69 patients [37%]; χ21 = 3.9; P = .05). Black infants had higher 60-day (White: 99 patients [9%] vs Black: 29 patients [15%]; χ21 = 6.7; P = .01) and in-hospital (White: 133 patients [12%] vs Black: 40 patients [21%]; χ21 = 10.6; P = .001) mortality . There were no mortality differences in Hispanic patients compared with White patients. On regression analyses, institutional diversity of 31% to 40% in Black patients (hazard ratio [HR], 0.17; 95% CI, 0.04-0.78; P = .02) and diversity greater than 40% in Hispanic patients (HR, 0.37; 95% CI, 0.15-0.89; P = .03) were associated with lower mortality without altering outcomes in White patients. Conclusions and Relevance: In this cohort study of 1565 who underwent surgical repair patients with CDH, Black infants had higher 60-day and in-hospital mortality after adjusting for disease severity. Hospitals treating a more racially and ethnically diverse patient population were associated with lower mortality in Black and Hispanic patients.

BACKGROUND: The objective was to explore the hospital-level relationship between routine pre-discharge WBC utilization (RPD-WBC) and outcomes in children with complicated appendicitis. METHODS: Multicenter analysis of NSQIP-Pediatric data from 14 consortium hospitals augmented with RPD-WBC data. WBC were considered routine if obtained within one day of discharge in children who did not develop an organ space infection (OSI) or fever during the index admission. Hospital-level observed-to-expected ratios (O/E) for 30-day outcomes (antibiotic days, imaging utilization, healthcare days, and OSI) were calculated after adjusting for appendicitis severity and patient characteristics. Spearman correlation was used to explore the relationship between hospital-level RPD-WBC utilization and O/E's for each outcome. RESULTS: 1528 children were included. Significant variation was found across hospitals in RPD-WBC use (range: 0.7-100%; p < 0.01) and all outcomes (mean antibiotic days: 9.9 [O/E range: 0.56-1.44, p < 0.01]; imaging: 21.9% [O/E range: 0.40-2.75, p < 0.01]; mean healthcare visit days: 5.7 [O/E 0.74-1.27, p < 0.01]); OSI: 14.1% [O/E range: 0.43-3.64, p < 0.01]). No correlation was found between RPD-WBC use and antibiotic days (r = +0.14, p = 0.64), imaging (r = -0.07, p = 0.82), healthcare days (r = +0.35, p = 0.23) or OSI (r = -0.13, p = 0.65). CONCLUSIONS: Increased RPD-WBC utilization in pediatric complicated appendicitis did not correlate with improved outcomes or resource utilization at the hospital level. LEVEL OF EVIDENCE: III. TYPE OF STUDY: Clinical Research.

Minimally invasive surgery (MIS) has improved surgical access to the foregut. While the benefits of MIS versus open surgery are well accepted, the relative benefits of laparoscopic versus robotic approaches continue to be debated. Procedure-specific comparisons are difficult to obtain for Heller myotomy, due to the relative rarity of the procedure in most practices. A retrospective review of prospectively collected perioperative data of a single surgical practice from 2001 to 2019 was conducted for the rate of perforation during Heller myotomy laparoscopically compared to robotically. From 2001 through February 2012, a laparoscopic approach was employed and from October 2008 to 2019, a robotic approach was employed. All perforations were recorded, as well as secondary outcomes of perforation location (gastric or esophageal), postoperative imaging for evidence of leak, length of stay, and complications. Chi-square and simple t test were employed for data analysis. During the 11 years of laparoscopic Heller myotomy, 14 cases resulted in 7 instances of perforation (50%). During the 11 years of robotic Heller myotomy, 45 cases resulted in 11 instances of perforation (24%) (p value = 0.06). All perforations in both groups were tiny, recognized, and repaired immediately. The length of stay (LOS) was longer in the laparoscopic perforation group (3.4 days) compared to the laparoscopic non-perforation group (1.2 days) (p value = 0.06). LOS for robotic was not significantly longer in the perforation group (2.8 days) compared to the robotic non-perforation group (1.5 days) (p value = 0.18). First time Heller myotomies showed a higher rate of perforation with laparoscopic (50%) vs robotic (14%) (p value = 0.009) approach. In subgroup analysis of revisional procedures, all ten were performed robotically (p value < 0.001) with a 60% perforation rate (p value = 0.001) and one associated, radiographically confirmed leak. Primary laparoscopic Heller myotomy related to more than four times the frequency of perforation than did primary robotic myotomy. We propose that the robotic platform provided the surgeon with superior ability to avoid perforation. Interestingly, the robotic group in this study dealt with more complex redo cases. In fact, reoperation in the area of the hiatus was a separate risk factor for perforation during robotic Heller myotomy. We recommend further prospective trials be done to better evaluate the benefits of robotic platform in regard to revisional foregut surgery.

Introduction: Spindle cell lipoma (SCL) is a rare subset of benign lipomatous neoplasms, making up approximately 1.5% of all adipocytic neoplasms. Since SCLs were first described in 1975, numerous nonclassical cases have been reported in the literature, with variation in location, cytologic composition, patient demographic, and progression. Although some previous reports review related cases of specific rare presentations or institution-based summaries, no comprehensive summary of published nonclassical SCL case reports has been done. Methods: PubMed was queried for nonclassical presentations of SCL from 1978 to 2018. The nonclassical characteristics were analyzed and described. Those with multiple nonclassical features were studied for common characteristics. The Fisher exact test was used, and a P value of 0.05 was determined to be statistically significant. Results: We present the first case of a patient with six nonclassical findings: a fast-growing, infiltrating into skeletal muscle, located in two positions on the chin of an 18-year-old African American woman. In this review of the existing nonclassical SCL, we evaluate 125 cases for demographics, location, size, erosion/infiltration, multiple lesions in one individual, and the number of nonclassical findings in one individual. Women and younger than 40-year-old patients significantly present with more than one nonclassical finding. Conclusions: Thorough characterization of the rare nonclassical cases of this benign condition could guide diagnostic decision-making and identify trends in disease presentation over time as well as alert the clinician to the increased risk of rapid regrowth or invasion in an individual with nonclassical findings especially young age and female gender.
RESUMEN
The superior gluteal artery perforator (SGAP) flap can be challenging and in common with all flaps can develop venous and arterial insufficiency. Several prior studies have demonstrated the successful utility of hyperbaric oxygen therapy (HBOT) in the salvage of compromised flaps, mainly with deep inferior epigastric perforator, latissimus dorsi or transverse rectus abdominis myocutaneous flaps. SGAP flaps are autologous alternatives to abdominal-based flaps and provides adequate adipose tissue for breast reconstruction. We report a case of a woman in her 50s who underwent a delayed bilateral breast reconstruction using SGAP free flaps. Postoperatively, venous congestion of her right breast flap was noted for which she was referred for HBOT. An acceptable aesthetic result was achieved following 17 HBOT treatments. This is the first case we can find in the published literature of ischaemic SGAP free flap being salvaged by HBOT.

BACKGROUND: The optimal timing of operative management in children with primary spontaneous pneumothorax (PSP) remains controversial. This study sought to determine early risk factors for failure of chest tube nonoperative management during the initial hospitalization in adolescents with PSP. METHODS: A retrospective review was conducted for children (aged ≤18 years) admitted to a single tertiary care referral center for their first presentation of a PSP managed with at least 48 h of chest tube decompression (CTD) alone. Patient outcomes and early risk factors for operative management were analyzed by multivariate regression. RESULTS: Of the 39 patients who met inclusion criteria, 15 (38.5%) patients failed nonoperative treatment while 24 (61.5%) patients were managed with CTD therapy alone. Progression to thoracoscopic surgery was associated with longer CTD of 8 vs 3 days and hospital length of stay of 9 vs 4 days when compared to nonoperative management (p < 0.001, both). Air leak and increase in pneumothorax size at 24 h after CTD were independently associated with progression to surgery (p = 0.007, p = 0.002). Combined, these risk factors were associated with a significant increase in recurrence (OR 6.00, 95% CI 1.11-41.11, p = 0.048). There were no significant differences between PSP management strategies regarding cumulative radiation exposure or 2 year recurrence. CONCLUSIONS: Air leak or increasing pneumothorax size within 24 h of CTD are highly correlated with failed nonoperative management during the initial hospitalization in pediatric patients with PSP. This data may be useful in the development of pediatric-specific treatment algorithms to optimally manage these patients. LEVEL OF EVIDENCE: Treatment study, Level III.

Importance: The ability of computed tomography (CT) to distinguish between benign congenital lung malformations and malignant cystic pleuropulmonary blastomas (PPBs) is unclear. Objective: To assess whether chest CT can detect malignant tumors among postnatally detected lung lesions in children. Design, Setting, and Participants: This retrospective multicenter case-control study used a consortium database of 521 pathologically confirmed primary lung lesions from January 1, 2009, through December 31, 2015, to assess diagnostic accuracy. Preoperative CT scans of children with cystic PPB (cases) were selected and age-matched with CT scans from patients with postnatally detected congenital lung malformations (controls). Statistical analysis was performed from January 18 to September 6, 2020. Preoperative CT scans were interpreted independently by 9 experienced pediatric radiologists in a blinded fashion and analyzed from January 24, 2019, to September 6, 2020. Main Outcomes and Measures: Accuracy, sensitivity, and specificity of CT in correctly identifying children with malignant tumors. Results: Among 477 CT scans identified (282 boys [59%]; median age at CT, 3.6 months [IQR, 1.2-7.2 months]; median age at resection, 6.9 months [IQR, 4.2-12.8 months]), 40 cases were extensively reviewed; 9 cases (23%) had pathologically confirmed cystic PPB. The median age at CT was 7.3 months (IQR, 2.9-22.4 months), and median age at resection was 8.7 months (IQR, 5.0-24.4 months). The sensitivity of CT for detecting PPB was 58%, and the specificity was 83%. High suspicion for malignancy correlated with PPB pathology (odds ratio, 13.5; 95% CI, 2.7-67.3; P = .002). There was poor interrater reliability (κ = 0.36 [range, 0.06-0.64]; P < .001) and no significant difference in specific imaging characteristics between PPB and benign cystic lesions. The overall accuracy rate for distinguishing benign vs malignant lesions was 81%. Conclusions and Relevance: This study suggests that chest CT, the current criterion standard imaging modality to assess the lung parenchyma, may not accurately and reliably distinguish PPB from benign congenital lung malformations in children. In any cystic lung lesion without a prenatal diagnosis, operative management to confirm pathologic diagnosis is warranted.

An autoamputated ovary (AO) is an extremely rare circumstance with a few reports in the literature. We present a case of a 3-month-old girl with a history of vague abdominal symptoms as well as a known ovarian mass, which was initially suspected to be benign and regressing. On laparoscopy for pain and obstructive symptoms, she was found to have an AO. The pathology was consistent with necrotic and torsed ovarian tissue with superimposed infection and possibly a cystic non-malignant teratoma. AOs are thought to originate from a torsion and are typically diagnosed incidentally. This is an interesting case of an AO causing a partial small bowel obstruction.
