Development of a Standardized Program for the Collaboration of Adult and Children's Surgeons.

BACKGROUND: Children's hospitals within larger hospitals (CH/LH) have the specific clinical advantage of easily facilitated collaboration between adult and children's surgeons. These collaborations, which we have termed hybrid surgical offerings (HSOs) are often required for disease processes requiring interventions that fall outside the customary practice of children's surgeons. Formal models to describe or evaluate these practices are lacking. METHODS: HSOs within a CH/LH were identified. Principles of systems-engineering were used to develop a standardized model (Children's Hybrid Enhanced Surgical Services [CHESS]) to describe and evaluate HSOs. Face validity was established via unstructured interviews of CH leaders and HSO surgeons. Areas for improved system-wide standardization and programmatic development were identified. RESULTS: HSOs were identified in collaboration with adult bariatric, minimally invasive, advanced endoscopic, endocrine, thoracic, and orthopedic trauma surgical services. The CHESS framework encompassed: 1) quality improvement metrics, 2) credentialing and oversight, 3) transitions of care, 4) pediatric family-centered care, 5) maintenance of the cycle of expertise, 6) continuing medical education, 7) scholarship. While HSOs fulfilled the majority of aforementioned programmatic domains across all six HSO-providing services, areas for improvement included maintaining a cycle of expertise (33%), quality improvement metrics (50%), and pediatric family-centered care (66%).  Additional noted advantages included faster translation of adult innovation to pediatric care and facilitation of emergency interdisciplinary care. CONCLUSION: Formal evaluation of HSOs is necessary to standardize and improve the quality of children's surgical care. Development of a structured framework such as CHESS addresses gaps in quality oversight and provides a basis for performance improvement, patient safety, and programmatic development.

The Association of Race, Sex, and Insurance With Transfer From Adult to Pediatric Trauma Centers.

OBJECTIVE: Our objective was to investigate whether racial/ethnic-based or payer-based disparities existed in the transfer practices of pediatric trauma patients from adult trauma center (ATC) to pediatric trauma center (PTC) in Pennsylvania. METHODS: Data on trauma patients aged 14 years or less initially evaluated at level I and II ATC were obtained from the Pennsylvania Trauma Outcome Study (2008-2012) (n = 3446). Generalized estimating equations regression analyses were used to evaluate predictors of subsequent transfer controlling for confounders and clustering. Recent literature has described racial and socioeconomic disparities in outcomes such as mortality after trauma; it is unknown whether these factors also influence the likelihood of subsequent interfacility transfer between ATC and PTC. RESULTS: Patients identified as nonwhite comprised 36.1% of the study population. Those without insurance comprised 9.9% of the population. There were 2790 patients (77.4%) who were subsequently transferred. Nonwhite race (odds ratio [OR], 4.3), female sex (OR, 1.3), and lack of insurance (OR, 2.3) were associated with interfacility transfer. Additional factors were identified influencing likelihood of transfer (increased odds: younger age, intubated status, cranial, orthopedic, and solid organ injury; decreased odds: operative intervention at the initial trauma center) (P < 0.05 for all). CONCLUSIONS: Although we assume that a desire for specialized care is the primary reason for transfer of injured children to PTCs, our analysis demonstrates that race, female sex, and lack of insurance are also associated with transfers from ATCs to PTCs for children younger than 15 years in Pennsylvania. Further research is needed to understand the basis of these health care disparities and their impact.

Clinical outcomes of neonatal and pediatric extracorporeal life support: A seventeen-year, single institution experience.

The objective of this study was to describe a single-center experience with neonatal and pediatric extracorporeal life support (ECLS) and compare patient-related outcomes with those of the Extracorporeal Life Support Organization (ELSO) Registry. A retrospective review of subject characteristics, outcomes, and complications of patients who received the ECLS at Penn State Health Children's Hospital (PSHCH) from 2000 to 2016 was performed. Fisher's exact test was used to compare the PSHCH outcomes and complications to the ELSO Registry report. Data from 118 patients were included. Survival to discontinuation of the ECLS was 70.3% and 65.2% to discharge/transfer. Following circuitry equipment changes, the survival to discharge/transfer improved for both neonatal (<29 days) and pediatric (29 days to <18 years) patients. The most common complications associated with ECLS were clinical seizures, intracranial hemorrhage, and culture-proven infection. ECLS for pulmonary support appeared to be associated with a higher risk of circuit thrombus and cannula problems. When compared to the ELSO Registry, low volume ECLS centers, like our institution, can have outcomes that are no different or statistically better as noted with neonatal and pediatric cardiac patients. Pediatric patients requiring pulmonary support appeared to experience more mechanical complications during ECLS suggesting the need for ongoing technological improvement.

Trends and Attributable Costs of Anorectal Involvement in Pediatric Crohn's Disease.

BACKGROUND: Pediatric Crohn's disease (CD) with anorectal involvement has not been well characterized. We sought to describe trends in the prevalence of pediatric CD with anorectal involvement and its influence on health-care utilization. MATERIALS AND METHODS: Patients (<21 y of age) with an International Classification of Diseases, Ninth Revision diagnosis of CD (555.X) were identified in the Kid's Inpatient Database (2003, 2006, 2009, 2012) and stratified by anorectal involvement based on the International Classification of Diseases, Ninth Revision diagnosis and procedural codes. Patient characteristics and resource utilization (length of stay [LOS] and costs) were compared between CD patients with and without anorectal involvement using univariate and multivariable analyses. Propensity score matching was used to estimate attributable LOS and costs. RESULTS: There were 26,029 patients with CD identified in the study interval. Of these, 1706 (6.6%) had anorectal involvement. Those with anorectal disease were younger (age 16 versus 17 y old), more likely to be male (59.4% versus 49.9%) and black or Hispanic (24.7% versus 18.2%), and were more commonly treated in urban teaching hospitals compared with rural or nonteaching hospitals (83.2% versus 70.9%) (P < 0.001 for all). The proportion of patients with anorectal involvement increased over time (odds ratio 1.03, 95% confidence interval 1.02-1.05). After propensity score matching, attributable LOS and costs were 0.5 d and approximately $1600, respectively. CONCLUSIONS: There has been an increase in the proportion of pediatric CD hospitalizations with anorectal manifestations. This pattern of disease is associated with longer hospitalization and higher costs compared with CD alone. Further research is required to understand the underlying etiology of these observed trends.

Childhood Injuries Due to Hay-Hole Falls: A 19-Year Experience at a Rural Pediatric Trauma Center.

OBJECTIVE: Children who live, work, and play on farms with barn design that includes hay-holes are at risk for a particular type of fall. This study retrospectively reviews all children admitted to a pediatric trauma center with injuries due to fall through a hay-hole over a 19-year period. This study is the first to specifically describe hay-hole fall injuries. METHODS: A retrospective review from a 19-year period at a rural pediatric trauma center identified 66 patients who sustained injuries from a hay-hole fall. Charts were reviewed for patient demographics, injuries, interventions, and hospital course. RESULTS: Sixty-six patients sustained injuries from hay-hole falls. Median patient age was 4 years, and median Injury Severity Score was 14. Forty-one percent of patients were admitted to the intensive care unit, and 26% of patients were intubated. Injuries included skull fracture (73%), facial fracture (27%), intracranial hemorrhage (53%), and noncraniofacial injuries (12%). Eighteen percent required a therapeutic intervention. There was 1 fatality (2%). CONCLUSIONS: Hay-hole fall appears to be a distinct injury mechanism, and patients present with different injury patterns than other types of falls. In this study, a high proportion of patients were young, and craniofacial injuries accounted for the majority of injuries. Only a small proportion of patients sustained noncraniofacial injuries. Injury prevention strategies should be targeted to this unique agrarian injury.

Interfacility transfer of pediatric trauma patients by helicopter does not predict the need for urgent intervention.

OBJECTIVES: Helicopter transport can allow trauma patients to reach definitive treatment rapidly, but its appropriate utilization for interfacility transfer to a pediatric trauma center (PTC) has not been well evaluated. This study evaluated differences in variables associated with transport type and intervention at a PTC between helicopter and ground transport for interfacility trauma transfers. METHODS: This retrospective study evaluated pediatric (<18 years old) trauma patients transferred to a rural PTC over a 5-year period. Records (n = 423) were evaluated for transport type, injuries, mechanism, interventions (eg, operations, transfusions, intubation), and treatment time points. Multiple logistic regression and Cox regression survival analyses were performed to evaluate associations with type of transport and interventions. RESULTS: Thirty-five percent of patients received intervention at the PTC, with no significant difference between transport types. Helicopter transport was associated with transport distance, respiratory rate greater than 30 breaths/min, pedestrian struck by auto, subdural hematoma, epidural hematoma, pneumothorax, solid organ injury, and vascular compromise/open fracture. Intervention was associated with epidural hematoma, extremity and pelvic fractures, vascular compromise/open fracture, penetrating neck/trunk injury, and complex laceration. Cox regression at less than 6, less than 4, and less than 2 hours after arrival at the PTC demonstrated similar intervention associations. Helicopter transport also correlated with intervention at these time points. CONCLUSIONS: Most pediatric trauma patients transferred by helicopter did not require interventions. Epidural hematoma, vascular compromise/open fracture, and penetrating neck/trunk injuries predicted prompt interventions (<2 hours) and may have benefited from helicopter transport. There was a disparity between the perceived need for rapid transport and the need for urgent interventions.

Successful application of the innovation process to a case of Floyd Type I tracheal agenesis.

Background: Innovation is broadly defined as the act of introducing a new product, idea, or process. The field of surgery is built upon innovation, revolutionizing technology, science, and tools to improve patient care. While most innovative solutions are aimed at problems with a significant patient population, the process can also be used on orphan pathologies without obvious solutions. We present a case of tracheal agenesis, a rare congenital anomaly with an overwhelming mortality and few good treatment options, that benefited from the innovation process and achieved survival with no ventilator dependence at three years of age. Methods: Utilizing the framework of the innovation process akin to the Stanford Biodesign Program, 1) the parameters of the clinical problem were identified, 2) previous solutions and existing technologies were analyzed, newly invented solutions were brainstormed, and value analysis of the possible solutions were carried out using crowd wisdom, and 3) the selected solution was prototyped and tested using 3D modeling, iterative testing on 3D prints of actual-sized patient parts, and eventual implementation in the patient after regulatory clearance. Results: A 3D-printed external bioresorbable splint was chosen as the solution. Our patient underwent airway reconstruction with "trachealization of the esophagus": esophageotracheal fistula resection, esophagotracheoplasty, and placement of a 3D-printed polycaprolactone (PCL) stent for external esophageal airway support at five months of age. Conclusions: The innovation process provided our team with the guidance and imperative steps necessary to develop an innovative device for the successful management of an infant survivor with Floyd Type I tracheal agenesis. Article summary: We present a case of tracheal agenesis, a rare congenital anomaly with an overwhelming mortality and few good treatment options, that benefited from the innovation process and achieved survival with no ventilator dependence at three years of age.The importance of this report is to reveal how the innovation process, which is typically used for problems with significant patient population, can also be used on orphan pathologies without obvious solutions.

Pediatric biliary disorders: Multimodality imaging evaluation with clinicopathologic correlation.

The spectrum of pathologies affecting the biliary tree in the pediatric population varies depending on the age of presentation. While in utero insults can result in an array of anatomic variants and congenital anomalies in newborns, diverse acquired biliary pathologies are observed in older children. These acquired pathologies display different presentations and consequences than adults. Multimodality imaging assessment of the pediatric biliary system is requisite to establishing an appropriate management plan. Awareness of the imaging features of the various biliary pathologies and conveying clinically actionable information is essential to facilitate appropriate patient management. In this paper, we will illustrate the anatomy and embryology of the pediatric biliary system. Then, we will provide an overview of the imaging modalities used to assess the biliary system. Finally, we will review the unique features of the pediatric biliary pathologies, complemented by histopathologic correlation and discussions of clinical management.

Complications and treatment failures of video-assisted thoracoscopic debridement for pediatric empyema.

PURPOSE: Video-assisted thoracoscopic debridement (VATD) is a well-established intervention to treat pediatric empyema. There is ongoing controversy at what stage in the treatment algorithm it should be utilized. To shed further light onto this debate, we reviewed our institutional experience looking for factors predicting treatment failure or complications of VATD. METHODS: We retrospectively analyzed data on patients that had undergone VATD for empyema from 1995 to 2008. We used independent sample t tests and Chi-square tests (SPSS) for statistical analysis. RESULTS: One hundred and fifty-two procedures in 151 patients [81 male (53.6%)] were identified. In 146 (96.7%) the etiology of the empyema was pulmonary, in 3 (1.98%) due to an infectious abdominal process and in 2 (1.3%) due to abdominal trauma. 118 patients (78.1%) were transferred from outside hospitals. 107 (70.1%) underwent VATD primarily, 44 (29.1%) following another procedure. The overall complication rate was 13.8%, most of which were minor. Treatment failures occurred in seven patients, resulting in three reoperations; two patients died. The average length of stay was 10.1 days, but was significantly longer if VATD followed another procedure or if a complication occurred. The risk for complications correlated with older age (6.2 vs. 8.8 years, p = 0.023) and lower hematocrit on admission (31.1 vs. 27.9%, p = 0.006). CONCLUSIONS: VATD provided effective treatment for pediatric empyema. Complications were mostly minor, occurring more frequently in older patients and those with a lower admission hematocrit. Early VATD decreased the length of hospitalization.

A Model for a Standardized and Sustainable Pediatric Anesthesia-Intensive Care Unit Hand-Off Process.

BACKGROUND AND OBJECTIVES: The hand-off process between pediatric anesthesia and intensive care unit (ICU) teams involves the exchange of patient health information and plays a major role in reducing errors and increasing staff satisfaction. Our objectives were to (1) standardize the hand-off process in children's ICUs, and (2) evaluate the provider satisfaction, efficiency and sustainability of the improved hand-off process. METHODS: Following multidisciplinary discussions, the hand-off process was standardized for transfers of care between anesthesia-ICU teams. A pre-implementation and two post-implementation (6 months, >2 years) staff satisfaction surveys and audits were conducted to evaluate the success, quality and sustainability of the hand-off process. RESULTS: There was no difference in the time spent during the sign out process following standardization-median 5 min for pre-implementation versus 5 and 6 min for post-implementation at six months and >2 years, respectively. There was a significant decrease in the number of missed items (airway/ventilation, venous access, medications, and laboratory values pertinent events) post-implementation compared to pre-implementation (p ≤ 0.001). In the >2 years follow-up survey, 49.2% of providers felt that the hand-off could be improved versus 78.4% in pre-implementation and 54.2% in the six-month survey (p < 0.001). CONCLUSION: A standardized interactive hand-off improves the efficiency and staff satisfaction, with a decreased rate of missed information at the cost of no additional time.

Primary Posterior Sagittal Anorectoplasty Outcomes for Rectovestibular and Perineal Fistulas Using an Accelerated Pathway: a Single Institution Study.

BACKGROUND: Posterior sagittal anorectoplasty (PSARP) is the most common surgical treatment for patients with anorectal malformations. Such patients are often subjected to prolonged nil per os (NPO), antibiotic use, and use of parenteral nutrition. Our aim was to review our institutional experience with patients undergoing PSARP using an accelerated standardized postoperative pathway. METHODS: Our hospital database was queried from 2004 to 2016 for patients diagnosed with imperforate anus who underwent a surgical procedure. Short term outcomes, hospital length of stay (LOS), and cost were evaluated. RESULTS: Sixty-three patients were identified during the study period. Of these patients, 34 (54.0%) had a fistula to the urogenital tract or had no demonstrable fistula and one cloaca and 29 (46.0%) had a fistula in the perineum. Approximately half of patients underwent primary PSARP, including 8 patients with fistulas located in the vestibule and vagina in girls and two with no apparent fistulas (12.7% of total cohort). Only two postoperative complications occurred: one superficial surgical site infection and one perineal wound dehiscence. Among the whole cohort, median LOS was 3 days. Median time to PO intake was 2 days, and median cost was $11,532. No complications occurred among the subset of 8 patients undergoing primary PSARP. CONCLUSION: Patients undergoing PSARP experienced similar outcomes compared to historical series, suggesting that the accelerated pathway for early refeeding and reduced use of antibiotics may be beneficial in appropriately selected patients. TYPE OF STUDY: Case series with no comparison group Level of evidence Level IV.

Understanding readmissions in children undergoing surgery: A pediatric NSQIP analysis.

BACKGROUND: Readmission is increasingly being utilized as an important clinical outcome and measure of hospital quality. Our aim was to delineate rates, risk factors, and reasons for unplanned readmission in pediatric surgery. MATERIALS AND METHODS: Retrospective review of pediatric patients (n=130,274) undergoing surgery (2013-2014) at hospitals enrolled in the Pediatric National Surgical Quality Improvement Program (NSQIP-P) was performed. Logistic regression was used to model factors associated with unplanned 30-day readmission. Reasons for readmission were reviewed to determine the most common causes of readmission. RESULTS: There were 6059 (n=4.7%) readmitted children within 30days of the index operation. Of these, 5041 (n=3.9%) were unplanned, with readmission rates ranging from 1.3% in plastic surgery to 5.2% in general pediatric surgery, and 10.8% in neurosurgery. Unplanned readmissions were associated with emergent status, comorbidities, and the occurrence of pre- or postdischarge postoperative complications. Overall, the most common causes for readmission were surgical site infections (23.9%), ileus/obstruction/gastrointestinal (16.8%), respiratory (8.6%), graft/implant/device-related (8.1%), neurologic (7.0%), or pain (5.8%). Median time from discharge to readmission was 8days (IQR: 3-14days). Reasons for readmission, time until readmission, and need for reoperative procedure (overall 28%, n=1414) varied between surgical specialties. CONCLUSION: The reasons for readmission in children undergoing surgery are complex, varied, and influenced by patient characteristics and postoperative complications. These data inform risk-stratification for readmission in pediatric surgical populations, and help to identify potential areas for targeted interventions to improve quality. They also highlight the importance of accounting for case-mix in the interpretation of hospital readmission rates. LEVEL OF EVIDENCE: 3.

Completely minimally invasive approach to restorative total proctocolectomy with j-pouch construction in children.

Restorative total proctocolectomy with J-pouch is a procedure used for children with severe ulcerative colitis or premalignant conditions like familial polyposis. The classic approach requires a laparotomy incision. Most published minimally invasive techniques still require a somewhat smaller incision to complete the procedure. We present a completely minimally invasive approach to accomplish the same goal, using a combined laparoscopic and endorectal technique and present our current clinical results with this method.

Costs of Clostridium difficile infection in pediatric operations: A propensity score-matching analysis.

BACKGROUND: The purpose of this analysis was to assess the burden of Clostridium difficile infection in the hospitalized pediatric surgical population and to characterize its influence on the costs of care. METHODS: There were 313,664 patients age 1-18 years who underwent a general thoracic or abdominal procedure in the Kids' Inpatient Database during 2003, 2006, 2009, and 2012. Logistic regression was used to model factors associated with the development of C difficile infection. A propensity score-matching analysis was performed to evaluate the influence of C difficile infection on mortality, duration of stay, and costs in similar patient cohorts. Population weights were used to estimate the national excess burden of C difficile infection on these outcomes. RESULTS: The overall prevalence of C difficile infection in the sampled cohort was 0.30%, with an increasing trend of C difficile infection over time in non-children's hospitals (P < .001). C difficile infection was associated with younger age, nonelective procedures, increasing comorbidities, and urban teaching hospital status (P < .001). An estimated 1,438 children developed C difficile infection after operation. After propensity score matching, the mean excess duration of stay and costs attributable to C difficile infection were 5.8 days and $12,801 (P < .001), accounting for 8,295 days spent in the hospital and $18.4 million (2012 USD) in spending annually. CONCLUSION: C difficile infection is a relatively uncommon but costly complication after pediatric operative procedures. Given the increasing trend of C difficile infection among hospitalized surgical patients, there is substantial opportunity for reduction of inpatient burden and associated costs in this potentially preventable nosocomial infection.

Connexin 43 gene expression in mice with cardiopulmonary developmental defects.

Gap junctions are vital for cellular integrity, including homeostasis, morphogenesis, differentiation and growth in normal development of organs such as heart. Connexin 43 (Cx43) is a major gap junction protein. Our cDNA microarray analysis of normal and nitrofen-exposed neonatal mice with hypoplastic lungs, associated congenital diaphragmatic hernia (CDH) and heart developmental defects showed up-regulation of Cx43. Our objective was to establish if cardiopulmonary defects in nitrofen-exposed mice may be linked to altered expression of the Cx43 gene. We addressed our objective by performing northern blot analysis, real-time RT-PCR, immunoblotting and immunohistochemistry by localizing Cx43 in hearts and lungs of normal and nitrofen-exposed mice at different gestational stages. The data confirmed up-regulation of Cx43 expression in both hearts and lungs of CDH neonate mice and in lungs at other developmental stages except the pseudoglandular stage. However, Cx43 protein levels were either the same or less in hearts and lungs of nitrofen-exposed mice than in normal tissues except in pseudoglandular lungs. Different expressions of mRNA and protein suggest possible post-transcriptional or translational defects in Cx43. We observed dysmorphic hearts with exaggerated interventricular grooves and deep notches at the apex of the hearts in nitrofen-exposed fetal/neonatal mice; narrowed pulmonary out-flow and various degrees of craniofacial defects in 15-20% of the affected mice. Our data suggest a possible involvement of Cx43 in craniofacial, heart and lung defects in nitrofen-exposed mice. Such cardiopulmonary defects are also observed in human newborns with CDH. Thus, the murine data may help elucidate the pathways of cardiopulmonary defects in the human newborn condition.

Measuring Surgical Site Infections in Children: Comparing Clinical, Electronic, and Administrative Data.

BACKGROUND: Surgical site infections (SSIs) are an important end point and measure of quality of care. Surgical site infections can be identified using clinical registries, electronic surveillance, and administrative claims data. This study compared measurements of SSIs using these 3 different methods and estimated their implication for health care costs. STUDY DESIGN: Data were obtained from 5,476 surgical patients treated at a single academic children's hospital (January 1, 2010 through August 31, 2014). Surgical site infections within 30 days were identified using a clinical registry in the NSQIP Pediatric, an electronic surveillance method (Nosocomial Infection Marker; MedMined), and billing claims. Infection rates, diagnostic characteristics, and attributable costs were estimated for each of the 3 measures of SSI. RESULTS: Surgical site infections were observed in 2.24% of patients per NSQIP Pediatric definitions, 0.99% of patients per the Nosocomial Infection Marker, and 2.34% per billing claims definitions. Using NSQIP Pediatric as the clinical reference, Nosocomial Infection Marker had a sensitivity of 31.7% and positive predictive value of 72.2%, and billing claims had a sensitivity of 48.0% and positive predictive value of 46.1% for detection of an SSI. Nosocomial Infection Marker and billing claims overestimated the costs of SSIs by 108% and 41%, respectively. CONCLUSIONS: There is poor correlation among SSIs measured using electronic surveillance, administrative claims, and clinically derived measures of SSI in the pediatric surgical population. Although these measures might be more convenient, clinically derived data, such as NSQIP Pediatric, may provide a more appropriate quality metric to estimate the postoperative burden of SSIs in children.

The Depression Index: an objective measure of the severity of pectus excavatum based on vertebral diameter, a morphometric correlate to patient size.

BACKGROUND/PURPOSE: In patients with Pectus Excavatum (PEX), the proposed Depression Index (DI) is derived from the absolute measurement of sternal depression using the transverse vertebral body diameter as a surrogate for height. The previously described objective and useful Pectus Index (PI) and Correction Index (CI), utilize thoracic diameters and do not always reflect the severity of the deformity as observed by clinicians. METHODS: Data for age, weight, height and vertebral diameter of T9, 10 and 11 were collected on 60 patients, with normal skeletons, undergoing CT scanning. The DI, PI and CI were calculated from CT scans on 76 patients with PEX. Indices were also compared to subjective rankings of the deformity from visual inspection of photographs by 5 clinicians. RESULTS: All parameters of age, weight and height correlated with the vertebral diameter. The DI correlated with the severity of the PEX deformity as also measured by the PI and the CI. There was a better correlation of the observed deformity severity to the DI than the PI or CI. CONCLUSION: There is a strong correlation between transverse vertebral size and patient height. The DI is an objective measurement of the severity of a PEX deformity that is independent of the thoracic diameters.

Comparing 30-day outcomes between thoracoscopic and open approaches for resection of pediatric congenital lung malformations: Evidence from NSQIP.

BACKGROUND/PURPOSE: Thoracoscopic surgery has been increasingly utilized in treating pediatric congenital lung malformations (CLM). Comparative studies evaluating 30-day outcomes between thoracoscopic and open resection of CLM are lacking. METHODS: There were 258 patients identified in pediatric NSQIP with a CLM and pulmonary resection in 2012-2013. Comparisons of patient characteristics and outcomes between surgical approaches were made using standard univariate statistics. In addition, a propensity score match was performed to evaluate outcomes in similar patient cohorts. RESULTS: One-hundred twelve patients (43.4%) received thoracoscopic resections and 146 patients (56.6%) received open resections. Patients undergoing open resections were more likely to be less than 5 months of age and have a comorbidity/preoperative condition (47.3% vs. 25.0%, p<0.001). The extent of resection was a lobectomy in 84.8% of thoracoscopic and 92.5% of open resection patients. Median operative time was similar between both groups (thoracoscopic 172 vs. open 153.5 minutes). On univariate analysis, thoracoscopic resection was associated with decreased postoperative complications (9.8% vs. 25.3%, p=0.001) and LOS (3 vs. 4 days, p<0.001). However, after adjusting for similar patient and operative characteristics, no significant differences were encountered between techniques. CONCLUSIONS: Thoracoscopic and open resection provide comparable 30-day outcomes and safety in the management of congenital lung malformations.

Endobronchial occlusion with one-way endobronchial valves: a novel technique for persistent air leaks in children.

PURPOSE: In children, persistent air leaks can result from pulmonary infection or barotrauma. Management strategies include surgery, prolonged pleural drainage, ventilator manipulation, and extracorporeal membrane oxygenation (ECMO). We report the use of endobronchial valve placement as an effective minimally invasive intervention for persistent air leaks in children. METHODS: Children with refractory prolonged air leaks were evaluated by a multidisciplinary team (pediatric surgery, interventional pulmonology, pediatric intensive care, and thoracic surgery) for endobronchial valve placement. Flexible bronchoscopy was performed, and air leak location was isolated with balloon occlusion. Retrievable one-way endobronchial valves were placed. RESULTS: Four children (16 months to 16 years) had prolonged air leaks following necrotizing pneumonia (2), lobectomy (1), and pneumatocele (1). Patients had 1-4 valves placed. Average time to air leak resolution was 12 days (range 0-39). Average duration to chest tube removal was 25 days (range 7-39). All four children had complete resolution of air leaks. All were discharged from the hospital. None required additional surgical interventions. CONCLUSION: Endobronchial valve placement for prolonged air leaks owing to a variety of etiologies was effective in these children for treating air leaks, and their use may result in resolution of fistulae and avoidance of the morbidity of pulmonary surgery.
