Abstract
BACKGROUND Surgical correction of tracheobronchomalacia (TBM) has evolved greatly over the past decade, with select pediatric institutions establishing dedicated surgery and anesthesia teams to navigate the complexities and challenges of surgical airway repairs. Although anesthetic techniques have evolved internally over many years to improve patient safety and outcomes, many of these methods remain undescribed in literature. TECHNIQUE In this article, we describe the intraoperative negative pressure suction test. This simulates the negative pressure seen in awake and spontaneously breathing patients, including the higher pressures seen during coughing which induce airway collapse in patients with TBM. Also known as the Munoz maneuver in surgical literature, this test has been performed on over 300 patients since 2015. DISCUSSION The negative pressure suction test allows for controlled intraoperative assessment of surgical airway repairs, replaces the need for risky intraoperative wake-up tests, increases the chances of a successful surgical repair, and improves anesthetic management for emergence and extubation. We provide a guide on how to perform the test and videos demonstrating its efficacy in intraoperative airway evaluation. CONCLUSIONS As surgeries to repair TBM become more prevalent in other pediatric institutions, we believe that pediatric patients and anesthesia providers will benefit from the insights and methods described here.

Abstract
PURPOSE Esophageal atresia with tracheoesophageal fistula (EA/TEF) is often associated with tracheobronchomalacia (TBM), which contributes to respiratory morbidity. Posterior tracheopexy (PT) is an established technique to treat TBM that develops after EA/TEF repair. This study evaluates the impact of primary PT at the time of initial EA/TEF repair. METHODS Review of all newborn primary EA/TEF repairs (2016-2021) at two institutions. Long-gap EA and reoperative cases were excluded. Based on surgeon preference and preoperative bronchoscopy, neonates underwent primary PT (EA + PT Group) or not (EA Group). Perioperative, respiratory and nutritional outcomes within the first year of life were evaluated. RESULTS Among 63 neonates, 21 (33%) underwent PT during EA/TEF repair. Groups were similar in terms of demographics, approach, and complications. Neonates in the EA + PT Group were significantly less likely to have respiratory infections requiring hospitalization within the first year of life (0% vs 26%, p = 0.01) or blue spells (0% vs 19%, p = 0.04). Also, they demonstrated improved weight-for-age z scores at 12 months of age (0.24 vs -1.02, p < 0.001). Of the infants who did not undergo primary PT, 10 (24%) developed severe TBM symptoms and underwent tracheopexy during the first year of life, whereas no infant in the EA + PT Group needed additional airway surgery (p = 0.01). CONCLUSION Incorporation of posterior tracheopexy during newborn EA/TEF repair is associated with significantly reduced respiratory morbidity within the first year of life.

Abstract
BACKGROUND Anastomotic strictures (AS) after esophageal atresia (EA) repair are common. While most respond to endoscopic therapy, some become refractory and require surgical intervention, for which the outcomes are not well established. METHODS All EA children with AS who were treated surgically at two institutions (2011-2022) were retrospectively reviewed. Surgical repair was performed for those with AS that were either refractory to endoscopic therapy or clinically symptomatic and undergoing surgery for another indication. Anastomotic leak, need for repeat stricture resection, and esophageal replacement were considered poor outcomes. RESULTS 139 patients (median age: 12 months, range 1.5 months-20 years; median weight: 8.1 kg) underwent 148 anastomotic stricture repairs (100 refractory, 48 non-refractory) in the form of stricturoplasty (n = 43), segmental stricture resection with primary anastomosis (n = 96), or stricture resection with a delayed anastomosis after traction-induced lengthening (n = 9). With a median follow-up of 38 months, most children (92%) preserved their esophagus, and the majority (83%) of stricture repairs were free of poor outcomes. Only one anastomotic leak occurred in a non-refractory stricture. Of the refractory stricture repairs (n = 100), 10% developed a leak, 9% required repeat stricture resection, and 13% required esophageal replacement. On multivariable analysis, significant risk factors for any type of poor outcome included anastomotic leak, stricture length, hiatal hernia, and patient's weight. CONCLUSIONS Surgery for refractory AS is associated with inherent yet low morbidity and high rates of esophageal preservation. Surgical repair of non-refractory symptomatic AS at the time of another thoracic operation is associated with excellent outcomes. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND The use of magnets for the treatment of long gap esophageal atresia or "magnamosis" is associated with increased incidence of anastomotic strictures; however, little has been reported on other complications that may provide insight into refining selection criteria for appropriate use. METHODS A single institution, retrospective review identified three cases referred for treatment after attempted magnamosis with significant complications. Their presentation, imaging, management, and outcomes were reviewed. RESULTS All three patients had prior cervical or thoracic surgery to close a tracheoesophageal fistula prior to magnamosis, creating scar tissue that can prevent magnet induced esophageal movement, leading to either magnets not attracting enough or erosion into surrounding structures. Two patients had a reported four centimeter esophageal gap prior to attempted magnamosis, both failing to achieve esophageal anastomosis, suggesting that these gaps were either measured on tension with variability in gap measurement technique, or that the esophageal segments were fixed in position from scar tissue and unable to elongate. One patient had severe tracheobronchomalacia requiring tracheostomy, with improvement in his airway after eventual tracheobronchopexies, highlighting that magnamosis does not address comorbidities often associated with this patient population. CONCLUSIONS We propose the following inclusion criteria and considerations for magnamosis: an esophageal gap truly less than four centimeters off tension with standardized measurement across centers, cautious use with a history of prior thoracic or cervical esophageal surgery, no associated tracheobronchomalacia or great vessel anomaly that would benefit from concurrent repair, and ideally to be used in centers equipped to manage potential complications. LEVEL OF EVIDENCE Level IV treatment study.

Abstract
BACKGROUND Indocyanine green (ICG) is commonly used to assess perfusion, but quality defining features are lacking. We sought to establish qualitative features of esophageal ICG perfusion assessments, and develop an esophageal anastomotic scorecard to risk-stratify anastomotic outcomes. METHODS Single institution, retrospective analysis of children with an intraoperative ICG perfusion assessment of an esophageal anastomosis. Qualitative perfusion features were defined and a perfusion score developed. Associations between perfusion and clinical features with poor anastomotic outcomes (PAO, leak or refractory stricture) were evaluated with logistic and time-to-event analyses. Combining significant features, we developed and tested an esophageal anastomotic scorecard to stratify PAO risk. RESULTS From 2019 to 2021, 53 children (median age 7.4 months) underwent 55 esophageal anastomoses. Median (IQR) follow-up was 14 (10-19.9) months; mean (SD) perfusion score was 13.2 (3.4). Fifteen (27.3%) anastomoses experienced a PAO and had significantly lower mean perfusion scores (11.3 (3.3) vs 14.0 (3.2), p = 0.007). Unique ICG perfusion features, severe tension, and primary or rescue traction-induced esophageal lengthening [Foker] procedures were significantly associated with PAO on both logistic and Cox regression. The scorecard (range 0-7) included any Foker (+2), severe tension (+1), no arborization on either segment (+1), suture line hypoperfusion >twice expected width (+2), and segmental or global areas of hypoperfusion (+1). A scorecard cut-off >3 yielded a sensitivity of 73% and specificity of 93% (AUC 0.878 [95%CI 0.777 to 0.978]) in identifying a PAO. CONCLUSIONS A scoring system comprised of qualitative ICG perfusion features, tissue quality, and anastomotic tension can help risk-stratify esophageal anastomotic outcomes accurately.

Abstract
BACKGROUND Anti-reflux procedures (ARP) in esophageal atresia (EA) patients can be challenging and prone to failure. These challenges become more evident with increasing complexity of EA. We sought to determine predictors of ARP failure in complex EA patients. METHODS Single-institution retrospective review of complex EA patients (e.g. long-gap EA, esophageal strictures, hiatal hernia, and reoperative ARP) who underwent an ARP from 2002 to 2019. ARP failure was defined as hiatal hernia recurrence, wrap migration/loosening, or need for reoperation. Predictors of failure were evaluated using univariate and multivariable time-to-event analysis. RESULTS 121 patients underwent 140 ARP at a median age of 13.5 months (IQR 7, 26.5). Nissen fundoplication (89%) was the most common ARP. Mesh (bovine pericardium) reinforcement was used in 41% of the patients. Median follow-up was 3.2 years (IQR 0.9, 5.8); 44 instances of ARP failure occurred (31%), though only 20 (14%) required reoperation. Median time to failure was 8.7 months (IQR 3.2, 25). Though fewer mesh-reinforced ARP failed (21% with vs 39% without, p = 0.02), on multivariable analysis only partial fundoplication (aHR 2.22 [95% CI 1.01-4.78]) and minimally invasive repair (aHR 2.57 [95% CI 1.12-6.01]) were significant predictors of ARP failure. CONCLUSION In our practice of complex EA patients, where ARP fail in nearly one third of cases, a Nissen fundoplication performed via laparotomy provided the lowest risk of ARP failure.

Abstract
BACKGROUND Radiographic assessment of esophageal growth in long-gap esophageal atresia while on traction and associated traction-related complications have not been described. OBJECTIVE To demonstrate how chest radiography can estimate esophageal position while on traction and to evaluate radiography's utility in diagnosing certain traction system complications. MATERIALS AND METHODS In this retrospective evaluation of portable chest radiographs obtained in infants with long-gap esophageal atresia who underwent the Foker process between 2014 and 2020, we assessed distances between the opposing trailing clips (esophageal gap) and the leading and trailing clips for each esophageal segment on serial radiographs. Growth during traction was estimated using longitudinal random-effects regression analysis to account for multiple chest radiograph measurements from the same child. RESULTS Forty-three infants (25 male) had a median esophageal gap of 4.5 cm. Median traction time was 14 days. Median daily radiographic esophageal growth rate for both segments was 2.2 mm and median cumulative growth was 23.6 mm. Traction-related complications occurred in 13 (30%) children with median time of 8 days from traction initiation. Daily change >12% in leading-to trailing clip distance demonstrated 86% sensitivity and 92% specificity for indicating traction-related complications (area under the curve [AUC] 0.853). Cumulative change >30% in leading- to trailing-clip distance during traction was 85% sensitive and 85% specific for indicating traction complications (AUC 0.874). CONCLUSION Portable chest radiograph measurements can serve as a quantitative surrogate for esophageal segment position in long-gap esophageal atresia. An increase of >12% between two sequential chest radiographs or >30% increase over the traction period in leading- to trailing-clip distance is highly associated with traction system complications.

Abstract
OBJECTIVE Although most children do well after operations to relieve vascular compression of the esophagus and airway, many will have persistent/recurrent symptoms. We review our surgical experience using a customized approach to correct various etiologies of failure after vascular ring/decompression surgery. METHODS Our institutional database identified children who underwent reoperation for persistent/recurrent symptoms after vascular ring or aberrant arterial decompression surgery between January 2014 and December 2019. Charts were reviewed for operative approaches and clinical data. Findings were analyzed by Fisher exact test for comparison between groups. RESULTS Twenty-seven children required reoperative surgery. Detailed preoperative workup identified 5 etiologies of failure for a customized approach. Residual scarring was corrected by lysis and rotational esophagoplasty (n = 23/27); fibrotic bands re-creating a ring were divided (n = 11); ongoing vascular compression was addressed by descending aortopexy (n = 19), aberrant subclavian division (n = 7), aortic uncrossing procedure (n = 4), and Kommerell resection (n = 8); anterior aortopexy (n = 6) and anterior tracheopexy (n = 9) corrected cartilage malformation; and tracheobronchomalacia was addressed with posterior airway pexy (n = 26). At available short-term follow-up (median 1 year), 21 of 22 patients (95%) had symptom improvement, and on bronchoscopy, the average number of airway sections with severe tracheobronchomalacia decreased from 2.8 ± 1.7 to 0.5 ± 0.9 (P < .001). CONCLUSIONS Persistent/recurrent symptoms after release of vascular compression are frequently caused by 5 different etiologies. A multidisciplinary strategy for workup and a customized operative approach can effectively treat these cases and may suggest opportunity at the index surgery to prevent reoperation and achieve optimal outcomes.

Abstract
OBJECTIVES Previous studies have demonstrated that infants are typically born with a left-greater-than-right forebrain asymmetry that reverses throughout the first year of life. We hypothesized that critically ill term-born and premature patients following surgical and critical care for long-gap esophageal atresia (LGEA) would exhibit alteration in expected forebrain asymmetry. METHODS Term-born (n = 13) and premature (n = 13) patients, and term-born controls (n = 23) <1 year corrected age underwent non-sedated research MRI following completion of LGEA treatment via Foker process. Structural T1- and T2-weighted images were collected, and ITK-SNAP was used for forebrain tissue segmentation and volume acquisition. Data were presented as absolute (cm3 ) and normalized (% total forebrain) volumes of the hemispheres. All measures were checked for normality, and group status was assessed using a general linear model with age at scan as a covariate. RESULTS Absolute volumes of both forebrain hemispheres were smaller in term-born and premature patients in comparison to controls (p < 0.001). Normalized hemispheric volume group differences were detected by T1-weighted analysis, with premature patients demonstrating right-greater-than-left hemisphere volumes in comparison to term-born patients and controls (p < 0.01). While normalized group differences were very subtle (a right hemispheric predominance of roughly 2% of forebrain volume), they represent a deviation from the expected pattern of hemispheric brain asymmetry. INTERPRETATION Our pilot quantitative MRI study of hemispheric volumes suggests that premature patients might be at risk of altered expected left-greater-than-right forebrain asymmetry following repair of LGEA. Future neurobehavioral studies in infants born with LGEA are needed to elucidate the functional significance of presented anatomical findings.

Abstract
INTRODUCTION We extended our pilot study in infants following long-gap esophageal atresia (LGEA) repair to report head circumference, an easily obtainable indirect measure of brain size. Data are presented in the context of previously reported body weight and T2-weighted MRI measures of intracranial and brain volumes. METHODS Clinical information and head circumference were obtained for term-born (n = 13) and premature (n = 13) infants following LGEA repair with Foker process, as well as healthy term-born controls (n = 20) <1-year corrected age who underwent non-sedated research MRI. General Linear Model univariate analysis with corrected age at scan as a covariate and Bonferroni adjusted p values assessed group differences. RESULTS We report no difference in head circumference between the three groups. Such findings paralleled trends in body weight and total intracranial volume but not in brain volume as previously reported for the same pilot cohort. DISCUSSION Results suggest uncompromised somatic and head growth after repair of LGEA. In contrast, a novel finding of discrepancy between head circumference (novel data) and brain size (previously published data) in the same cohort suggests that head circumference might not be the best indirect measure of brain size in selected group of patients.

Abstract
OBJECTIVES/HYPOTHESIS The recurrent laryngeal nerve (RLN) is at risk during pediatric cervical, thoracic, and cardiac surgery. We aim to determine the feasibility and effectiveness of RLN monitoring techniques in all pediatric patients. STUDY DESIGN Retrospective case series. METHODS Retrospective review of patients/procedures with RLN(s) at risk and RLN monitoring at Boston Children's Hospital July 2019-October 2020. Primary outcomes: pre/postoperative vocal fold mobility by awake flexible fiberoptic laryngoscopy (FFL). RESULTS One hundred one patients (median [interquartile range, IQR] age 14.6 months [4.6-49.7 months], weight 10 kg [5.2-16.2 kg]) underwent 122 procedures with RLN(s) at risk. RLN monitoring attempted 111 cases, successful 96 (84%). Surgical indications: esophageal atresia/tracheoesophageal fistula, and tracheobronchomalacia. Sixty-two (56%) procedures in reoperative field. Median follow-up 112 days (IQR 41-230). Pre/postoperative FFL performed 84 procedures (69%), 19 new postoperative RLN injuries (16%), median age 12 months, reoperative fields 11 (18%). Prass probes: 34 cases (28 successful, 82%), 6 injuries (18%), age 12.2 (5.8-23.6) months. Dragonfly electrodes: 45 cases (37 successful, 82%), 8 injuries (18%), age 7.5 (3.8-19) months. Nerve integrity monitoring (NIM) integrated electrode endotracheal tube: 33 cases (33 successful, 100%), 5 injuries (15%), age 90 (58.8-136.7) months. Automatic periodic stimulation (APS): 16 cases, 13 successful (81%), four injuries (25%), age 7.2 (5.3-20.6) months. NIM RLN monitoring is significantly more successful than Prass, Dragonfly (95%CI -0.3 to 0.02, P = .02; and 95%CI 0.05-0.31, P = .008). Rates of injury are not different between types of RLN monitoring (P = .94), with APS use (P = .47), or with monitoring success (95%CI -0.36 to 0.09, P = .28). CONCLUSIONS RLN monitoring is feasible in pediatric patients of all ages. Although NIM type RLN monitoring success is superior, all forms offer similar rates of nerve protection.

Abstract
Airway collapse from dynamic tracheobronchomalacia (TBM), static compression from vascular compression, and/or tracheobronchial deformation are challenging conditions. Patients are best assessed and managed by a multidisciplinary team in centers specializing in complex pediatric airway disorders. Suspicion is made through clinical history and physical examination, diagnosis of location and severity by dynamic 3-phase bronchoscopy, and surgical treatment planning by MDCT and other studies as necessary to completely understand the problems. The treatment plan should be patient-based with a thorough approach to the underlying pathology, clinical concerns, and combined abnormalities. Patients should undergo maximum medical therapy prior to committing to other interventions. For those children considered candidates for surgical intervention, all other associated conditions, including vascular anomalies, chest wall deformities, mediastinal lesions, or other airway pathologies, should also be considered. Our preference is to correct the airway lesions at the same operation as other comorbidities, if possible, to prevent multiple reoperations with their attendant increased risks. We also strongly advocate for the use of recurrent laryngeal nerve monitoring in all cases of cervical or thoracic surgery to minimize the risks to vocal cord function and laryngeal sensation. Studies that evaluate the effect of these interventions on the patient and caregiver's quality of life are needed to fully grasp the impact of TBM on this challenging patient population.

Abstract
BACKGROUND Esophageal anastomoses are at risk for leak or stricture. Negative pressure vacuum-assisted closure (VAC) therapy is used to treat leak. We hypothesized that a prophylactic VAC (pEVAC) at the time of new anastomosis may lead to fewer leaks and strictures. METHODS Single center retrospective case-control study of patients undergoing high-risk esophageal anastomoses between July 2015 and January 2019. Outcomes of leak and long-term anastomotic failure (refractory stricture requiring surgery) were compared between groups. RESULTS Sixteen patients had a pEVAC placed during LGEA repair (N = 10) or stricture resection (N = 6). Of pEVAC cases, 3 (N = 1 Foker, N = 2 stricture resections) experienced leak (18.8%). In comparison, leak occurred in 9/41 (22%) Foker patients and in 1/20 (5%) stricture resections without pEVAC, all p > 0.05. Long-term anastomotic failure was more common in the pEVAC cohort versus controls (56.3% versus 11.5%, p < 0.001). CONCLUSIONS Prophylactic EVAC placement does not appear to reduce leak and is associated with significantly greater odds of long-term anastomotic failure. Further device refinement could improve its potential role in prophylaxis of high-risk anastomoses, but future research is needed to better understand optimal patient selection, device design, and duration of pEVAC therapy.

Abstract
PURPOSE We describe a left-sided approach for long gap esophageal atresia (LGEA) repair in patients who have a large leftward upper pouch and no significant tracheomalacia, or as a salvage strategy after prior failed right-sided repairs. METHODS Retrospective review of patients who underwent repair via traction induced growth (Foker procedure [FP]) from 2014 to 2019 was performed. Surgical technique and post-operative outcomes were evaluated. RESULTS Of 47 LGEA patients, 18 (38%) were approached via the left side - 94% had a left aortic arch, and 22% had prior attempts at a right-sided anastomosis. More left-sided patients underwent minimally invasive repair (39% vs 7%, p = 0.007) and internal traction (50% vs 10%, p = 0.002) compared to right-sided patients. On multivariate analysis, internal traction was associated with a decreased length of paralysis (p<0.01); length of intubation and hospital stay were similar between groups. Anastomotic leak (17% vs 20%, p = 0.80) and stricture resection (6% vs 24%, p = 0.12) rates were similar. No left-sided FP patient required additional surgery for tracheomalacia, while six right-sided patients required intervention. CONCLUSION Left-sided FP can be considered for LGEA patients with a large leftward upper pouch or as a salvage pathway after a failed right chest approach, with similar outcomes to the right-sided approach.

Abstract
Objective To report our experience with novel external tracheal and bronchial placed bioresorbable splints in children with severe symptomatic airway collapse. Methods Retrospective review of patients undergoing bioresorbable splint placement. Results Between July 2018 and February 2020, 14 patients received 16 external splints (trachea, n = 8; left bronchus, n = 7; and right bronchus, n = 1). Preoperatively, 7 patients had a tracheostomy; 6 of them were receiving mechanical ventilation with ventilator settings so high that they required an inpatient setting, often in an intensive care unit. Median age at implant was 14.5 months (range, 2 months-14 years). Splints were formed from moldable bioresorbable plates (RapidSorb; Synthes, Oberdorf, Switzerland) and were customized intraoperatively around a Hegar dilator. A series of Prolene sutures were placed through into the airway cartilage under simultaneous bronchoscopic and direct visualization and then tied securing the airway within the splint. Concomitant procedures were also performed in the region of the airway splints, consisting of airway reconstruction, cardiovascular procedures, and/or esophageal rotation (related to posterior tracheopexy). Median follow-up was 20 months (interquartile range, 12-21 months). Four patients required no further intervention. Although not necessarily in the splinted region, 7 patients required additional procedures, including posterior tracheobronchopexy (n = 2), temporary tracheal stent placement (n = 1), tracheal resection with end-to-end anastomosis (n = 1), closure tracheostomy (n = 1), and tracheostomy placement (n = 2). One patient required splint replacement and in 1 patient, the splint was removed later. All patients (except 2 deaths from unrelated causes) were discharged home. Three patients required mechanical ventilation at lower settings that allowed home ventilation (1 of those only at night), and 4 patients required tracheostomy collar. Indications for tracheostomy included subglottic stenosis, vocal cord paralysis, pulmonary insufficiency, small airway malacia, and laryngomalacia. Conclusions An external bioresorbable splint can provide temporary external support while allowing the age-proportional growth of the airway. We applied readily available bioresorbable plates that were custom-molded based on the location, shape, and length of the collapsing airway in selected patients presenting with severe tracheobronchomalacia from loss of structural support and/or cartilage deformation. Further study that includes long-term outcomes are necessary to define the best role for these external splints as part of comprehensive airway management.

Abstract
BACKGROUND The jejunal interposition is our preferred esophageal replacement route when the native esophagus cannot be reconstructed. We report the evolution of our approach and outcomes. METHODS The study was a single-center retrospective review of children undergoing jejunal interposition for esophageal replacement. Outcomes were compared between historical (2010-2015) and contemporary cohorts (2016-2019). RESULTS Fifty-five patients, 58% male, median age 4 years (interquartile range 2.4-8.3), with history of esophageal atresia (87%), caustic (9%) or peptic (4%) injury, underwent a jejunal interposition (historical cohort n = 14; contemporary cohort n = 41). Duration of intubation (11 vs 6 days; P = .01), intensive care unit (22 vs 13 days; P = .03), and hospital stay (50 vs 27 days; P = .004) were shorter in the contemporary cohort. Anastomotic leaks (7% vs 5%; P = .78), anastomotic stricture resection (7% vs 10%; P = .74), and need for reoperation (57% vs 46%; P = .48) were similar between cohorts. Most reoperations were elective conduit revisions. Microvascular augmentation, used in 70% of cases, was associated with 0% anastomotic leaks vs 18% without augmentation; P = .007. With median follow-up of 1.9 years (interquartile range 1.1, 3.8), 78% of patients are predominantly orally fed. Those with preoperative oral intake were more likely to achieve consistent postoperative oral intake (87.5% vs 64%; P = .04). CONCLUSION We have made continuous improvements in our management of patients undergoing a jejunal interposition. Of these, microvascular augmentation was associated with no anastomotic leaks. Despite its complexity and potential need for conduit revision, the jejunal interposition remains our preferred esophageal replacement, given its excellent long-term functional outcomes in these complex children who have often undergone multiple procedures before the jejunal interposition.

Abstract
Tracheobronchomalacia (TBM) is an excessive dynamic narrowing of the airway that is greatest with increased mediastinal pressure such as coughing, Valsalva, and forced expiration. Airway compression and/or cartilage malformation is a fixed or static narrowing of the airway typically caused by great vessel malposition and/or abnormalities and may also contribute to airway narrowing. Although imprecise and misleading, the term TBM is often used to represent both problems, static and dynamic airway narrowing, which only serves to confuse and may mislead the treatment team into ineffective therapies. The consequences of airway narrowing caused by dynamic TBM and/or static compression includes a range of clinical signs and symptoms, depending on the location, extent, and severity of the airway collapse. All patients with mild to severe TBM benefit from medical management to optimize airway clearance of mucus. The milder cases of TBM may become asymptomatic with this therapy, allowing time for the child to grow and the airway to enlarge without the consequences of recurrent infections. In cases of more severe TBM with clinical sequelae, more aggressive management may be warranted. Multiple options for surgical intervention are available. This article discusses the details of clinical presentation, evaluation, diagnosis, and a variety of treatments.

Abstract
BACKGROUND A recurrent tracheo-esophageal fistula can complicate esophageal atresia and tracheo-esophageal fistula (TEF) repair in children. Therapeutic approaches and the rate of recurrence vary widely. Most reports are limited by small cohorts and short-term follow-up, and rates of re-recurrence are substantial, making it difficult to select the treatment of choice. We aimed to review our experience with the treatment of recurrent TEF using posterior tracheopexy, focusing on operative risks and long-term outcomes. STUDY DESIGN We conducted a retrospective review of patients with esophageal atresia TEF with recurrent TEF treated at 2 institutions from 2011 to 2020. We approach recurrent TEFs surgically. Once the TEF is divided and repaired, the membranous trachea is sutured to the anterior longitudinal ligament of the spine (posterior tracheopexy) and the esophagus is rotated into the right chest (rotational esophagoplasty), separating the suture lines widely. To detect re-recurrence, patients undergo endoscopic surveillance during follow-up. RESULTS Sixty-two patients with a recurrent TEF were surgically treated (posterior tracheopexy/rotational esophagoplasty) at a median age of 14 months. All had significant respiratory symptoms. On referral, 24 had earlier failed endoscopic and/or surgical attempts at repair. Twenty-nine required a concomitant esophageal anastomotic stricturoplasty or stricture resection. Postoperative morbidity included 3 esophageal leaks, and 1 transient vocal cord dysfunction. We have identified no recurrences, with a median follow-up of 2.5 years, and all symptoms have resolved. CONCLUSIONS The surgical treatment of recurrent TEFs that incorporates a posterior tracheopexy and rotational esophagoplasty is highly effective for preventing re-recurrence with low perioperative morbidity.

Abstract
Anastomotic stricture is a common complication of esophageal atresia (EA) repair. Such strictures are managed with dilation or other therapeutic endoscopic techniques such as steroid injections, stenting, or endoscopic incisional therapy (EIT). In situations where endoscopic therapy is unsuccessful, patients with refractory strictures may require surgical stricture resection; however, the point at which endoscopic therapy should be abandoned in favor of repeat thoracotomy is unclear. We hypothesized that increasing numbers of therapeutic endoscopies are associated with increased likelihood of stricture resection. We retrospectively reviewed the records of patients with EA who had an initial surgery at our institution resulting in an esophago-esophageal anastomosis between August 2005 and May 2019. Up to 2 years of post-surgery endoscopy data were collected, including exposure to balloon dilation, intralesional steroid injection, stenting, and EIT. Primary outcome was need for stricture resection. Receiver operating characteristic (ROC) curve analysis and univariate and multivariable Cox proportional hazards regression analyses were performed. There were 171 patients who met inclusion criteria. The number of therapeutic endoscopies was a moderate predictor of stricture resection by ROC curve analysis (AUC = 0.720, 95% CI 0.617-0.823). With increasing number of therapeutic endoscopies, the probability of remaining free from stricture resection decreased. By Youden's J index, a cutoff of ≥7 therapeutic endoscopies was optimal for discriminating between patients who had versus did not have stricture resection, though an absolute majority of patients (≥50%) remained free of stricture resection at each number of therapeutic endoscopies through 12 endoscopies. Significant predictors of needing stricture resection by univariate regression included ≥7 therapeutic endoscopies, Foker surgery for long-gap EA, fundoplication, history of esophageal leak, and length of stricture ≥10 mm. Multivariate analysis identified only history of leak as statistically significant, though this regression was underpowered. The utility of repeated therapeutic endoscopies may diminish with increasing numbers of endoscopic therapeutic attempts, with a cutoff of ≥7 endoscopies identified by our single-center experience as our statistically optimal discriminator between having stricture resection versus not; however, a majority of patients remained free of stricture resection well beyond 7 therapeutic endoscopies. Though retrospective, this study supports that repeated therapeutic endoscopies may have clinical utility in sparing surgical stricture resection. Esophageal leak is identified as a significant predictor of needing subsequent stricture resection. Prospective study is needed.

Abstract
BACKGROUND & AIMS Congenital esophageal stenosis (CES) is an inborn condition of the esophagus that can be refractory to endoscopic dilation. Surgical intervention is not curative, with patients experiencing frequent ongoing need for therapy for anastomotic stricture postoperatively. We hypothesized that novel methods of endoscopic CES management including endoscopic incisional therapy (EIT) would lead to less surgical intervention. METHODS We retrospectively reviewed the medical records of all patients with CES treated by our tertiary care center who had at least one endoscopy between July 2007 and July 2019. Statistical comparison of cohorts who underwent advanced endoscopic therapy involving EIT versus traditional endoscopic therapy with balloon dilation was performed. Primary outcome measure was need for surgical intervention. RESULTS Thirty-six patients with CES met inclusion criteria. Thirty-four ever had at least one endoscopic intervention such as balloon dilation, steroid injection, stenting, and/or endoscopic incisional therapy (EIT) at their CES. Esophageal vacuum assisted closure (EVAC) was used for treatment or prevention of esophageal leak. Odds of surgical intervention were significantly lower in the group who received therapeutic endoscopy with EIT (odds ratio (OR) 0.1; p = 0.007). Clinical feeding outcomes were similar in the endoscopic and surgical management groups. Odds of complications after therapeutic endoscopies involving EIT were significantly greater than those without EIT (odds ratio 6.39; 95% confidence interval (2.34, 17.44); p < 0.001), though our rates of esophageal leak significantly decreased over time as our use of EVAC increased (Spearman's ρ = -0.884; p = 0.004). CONCLUSION Complementary endoscopic techniques such as EIT broaden the toolbox of the treating physician and may allow for avoidance of surgery in CES. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND Tracheobronchomalacia and airway obstruction from severely dilated pulmonary arteries in tetralogy of Fallot with absent pulmonary valve (TOF-APV) has been associated with high rates of respiratory failure and mortality (15% to 25%). It is not known whether aggressive pulmonary artery (PA) or direct airway intervention during early definitive cardiac repair improves outcomes. METHODS A retrospective observational study was made of all patients undergoing surgical repair for TOF-APV at our center between 2006 and 2018. RESULTS Twenty patients underwent repair at a median age of 51 days and PA Z-scores of 8.1. Twelve patients had a valve implanted, 6 of whom required reoperation for valve replacement at a median of 9 months (range, 3 to 28) compared with 8 who had initial transannular patch, and only 1 patient required subsequent valve replacement (P < .05). Seven patients had central PAs replaced with thin-walled Gore-Tex (WL Gore, Flagstaff, AZ) grafts; none of these required PA reoperation during a median follow-up of 26.5 months, whereas 3 of 13 patients who did not have PA replacement with Gore-Tex required subsequent PA reoperation (P < .05). Concomitant airway interventions (eg, tracheobronchopexy/plasty) were performed in 4 patients and none required subsequent airway interventions, whereas 2 patients not having initial airway intervention required subsequent tracheopexy (P < .05). Three patients in the cohort eventually required tracheostomy (15%), and 2 patients died (10%; on postoperative days 30 and 326); none had received initial airway intervention. CONCLUSIONS Pulmonary artery replacement and aggressive direct airway management at initial definitive repair of cardiac TOF-APV can be performed safely with acceptable survival outcomes and low rates of airway and PA reintervention.

Abstract
BACKGROUND Tracheobronchial compression (TBC) from great vessel anomalies (GVA) can contribute to tracheobronchomalacia (TBM) symptoms. The frequency, impact on symptoms and optimal management of GVA in these patients, with or without a history of esophageal atresia (EA), are still unclear. STUDY DESIGN Patients who underwent surgery for TBM/ TBC between 2001 and 2017 were reviewed. Demographics, type of GVA, and operative interventions were collected. The frequency and treatment modalities of GVA between EA and non-EA patients were compared. RESULTS Overall, 209 patients met criteria; 120 (57.4%) patients had at least one GVA, including double aortic arches (n = 4, 1.9%), right aortic arches (n = 14, 6.7%), aberrant right subclavian arteries (n = 15, 7.2%), and innominate artery compression (n = 71, 34.0%). Non-EA patients were more likely to have surgery later in life (29.5 months versus 16 months, p = 0.0002), double aortic arch (p = 0.0174), right aortic arch (p < 0.0001), and undergo vascular reconstruction concurrently with their airway procedure (25% vs 8.4%, p = 0.002). Vessel reconstruction was performed in 25 patients; six required cardiac bypass. CONCLUSION The frequency of GVA in patients with symptomatic airway collapse is substantial. Multidisciplinary evaluation is imperative for operative planning as many require complex reconstruction and collaboration with cardiac surgery, particularly patients without a history of EA.

Abstract
INTRODUCTION Fashioning a patent, watertight anastomosis in patients with esophageal atresia is a challenging task in pediatric surgery, particularly when performed under tension. A reproducible suture-less alternative would decrease operative time. We evaluated magnetic esophageal compression anastomoses in a novel bypass-loop swine model. METHODS Eight-week-old piglets underwent thoracotomy to mobilize the esophagus at the carina to create a U-shaped loop. Custom-made 8 mm diameter Neodymium Magnets were inserted into the esophagus proximal and distal to the loop, then mated side-to-side at the future anastomosis site. Pigs were observed for 8 (n = 4), 10 (n = 6), and 12 (n = 2) days and then sacrificed. The magnetic compression anastomosis was evaluated macroscopically, by radiography, burst pressure testing, and histology. RESULTS All 12 pigs survived until the endpoint. Separation of the magnets occurred at a median of 9 days. Contrast esophagrams showed patency and no leak. All anastomoses withstood pressures well over 13 kPa without leak. Histopathology showed epithelialized circular scar tissue. CONCLUSION Magnetic compression anastomoses of the esophagus using our specially-designed magnets are formed between the 8th and 10th postoperative day, are patent and mechanically resistant to supraphysiologic intraluminal pressures. These data lay the basis for a potential clinical application in patients born with esophageal atresia. LEVEL OF EVIDENCE Not applicable (experimental animal study).

Abstract
Objective: Review techniques for intraoperative recurrent laryngeal nerve (RLN) monitoring during pediatric surgery for esophageal atresia, tracheoesophageal fistula, tracheobronchomalacia, and cardiac surgery. Summary Background Data: Literature was reviewed for reports of intraoperative recurrent laryngeal nerve monitoring in cervical, thoracic, and cardiac surgical procedures which place the RLNs at risk for injury. Methods: Review paper. Results: The RLN is at risk during pediatric surgery for esophageal atresia, tracheoesophageal fistula, tracheobronchomalacia, and cardiac surgery. Intraoperative nerve monitoring has decreased rates of RLN injury in thyroid surgery. Intraoperative RLN monitoring techniques appropriate for pediatric surgery are discussed, including endotracheal tubes with integrated surface electrodes, adhesive surface electrodes for smaller endotracheal tubes, endolaryngeal electrodes, and automatic periodic continuous intra-operative stimulation. Conclusions: Multiple techniques exist to monitor the RLN in children undergoing cervical, cardiac, and thoracic surgery. Monitoring the RLN during procedures that place the RLNs at risk may help decrease the rate of RLN injury.

Abstract
We previously showed that infants born with long-gap esophageal atresia (LGEA) demonstrate clinically significant brain MRI findings following repair with the Foker process. The current pilot study sought to identify any pre-existing (PRE-Foker process) signs of brain injury and to characterize brain and corpus callosum (CC) growth. Preterm and full-term infants (n = 3/group) underwent non-sedated brain MRI twice: before (PRE-Foker scan) and after (POST-Foker scan) completion of perioperative care. A neuroradiologist reported on qualitative brain findings. The research team quantified intracranial space, brain, cerebrospinal fluid (CSF), and CC volumes. We report novel qualitative brain findings in preterm and full-term infants born with LGEA before undergoing Foker process. Patients had a unique hospital course, as assessed by secondary clinical end-point measures. Despite increased total body weight and absolute intracranial and brain volumes (cm3) between scans, normalized brain volume was decreased in 5/6 patients, implying delayed brain growth. This was accompanied by both an absolute and relative CSF volume increase. In addition to qualitative findings of CC abnormalities in 3/6 infants, normative CC size (% brain volume) was consistently smaller in all infants, suggesting delayed or abnormal CC maturation. A future larger study group is warranted to determine the impact on the neurodevelopmental outcomes of infants born with LGEA.

Abstract
Tracheobronchomalacia (TBM) refers to airway collapse due to typically excessive posterior membrane intrusion and often associated with anterior cartilage compression. TBM occurs either in isolation or in association with other congenital or acquired conditions. Patients with TM typically present non-specific respiratory symptoms, ranging from noisy breathing with a typical barking cough to respiratory distress episodes to acute life-threatening events and recurrent and/or prolonged respiratory infections. There are no definitive standardized guidelines for the evaluation, diagnosis, and treatment of TBM; therefore, patients may be initially misdiagnosed and incorrectly treated. Although milder cases of TBM may become asymptomatic as the diameter of the airway enlarges with the child, in cases of severe TBM, more aggressive management is warranted. This article is an overview of the clinical presentation, evaluation, diagnosis, medical management, and surgical treatment options in pediatric tracheomalacia.

Abstract
Objective: To determine brain magnetic resonance imaging (MRI) measures of cerebrospinal fluid (CSF) and whole brain volume of full-term and premature infants following surgical treatment for thoracic non-cardiac congenital anomalies requiring critical care. Methods: Full-term (n = 13) and pre-term (n = 13) patients with long-gap esophageal atresia, and full-term naïve controls (n = 19) < 1 year corrected age, underwent non-sedated brain MRI following completion of thoracic non-cardiac surgery and critical care treatment. Qualitative MRI findings were reviewed and reported by a pediatric neuroradiologist and neurologist. Several linear brain metrics were measured using structural T1-weighted images, while T2-weighted images were required for segmentation of total CSF and whole brain tissue using the Morphologically Adaptive Neonatal Tissue Segmentation (MANTiS) tool. Group differences in absolute (mm, cm3) and normalized (%) data were analyzed using a univariate general linear model with age at scan as a covariate. Mean normalized values were assessed using one-way ANOVA. Results: Qualitative brain findings suggest brain atrophy in both full-term and pre-term patients. Both linear and volumetric MRI analyses confirmed significantly greater total CSF and extra-axial space, and decreased whole brain size in both full-term and pre-term patients compared to naïve controls. Although linear analysis suggests greater ventricular volumes in all patients, volumetric analysis showed that normalized ventricular volumes were higher only in premature patients compared to controls. Discussion: Linear brain metrics paralleled volumetric MRI analysis of total CSF and extra-axial space, but not ventricular size. Full-term infants appear to demonstrate similar brain vulnerability in the context of life-saving thoracic non-cardiac surgery requiring critical care as premature infants.

Abstract
Purpose We review outcomes of posterior tracheopexy for tracheomalacia in esophageal atresia (EA) patients, comparing primary treatment at the time of initial EA repair versus secondary treatment. Methods All EA patients who underwent posterior tracheopexy from October 2012 to September 2016 were retrospectively reviewed. Clinical symptoms, tracheomalacia scores, and persistent airway intrusion were collected. Indication for posterior tracheopexy was the presence of clinical symptoms, in combination with severe tracheomalacia as identified on bronchoscopic evaluation, typically defined as coaptation in one or more regions of the trachea. Secondary cases were usually those with chronic respiratory symptoms who underwent bronchoscopic evaluation, whereas primary cases were those found to have severe tracheomalacia on routine preoperative dynamic tracheobronchoscopy at the time of initial EA repair. Results A total of 118 patients underwent posterior tracheopexy: 18 (15%) primary versus 100 (85%) secondary cases. Median (interquartile range) age was 2 months (1–4 months) for primary (22% type C) and 18 months (8–40 months) for secondary (87% type C) cases (p < 0.001). There were statistically significant improvements in most clinical symptoms postoperatively for primary and secondary cases, with no significant differences in any postoperative symptoms between the two groups (p > 0.1). Total tracheomalacia scores improved significantly in primary (p = 0.013) and secondary (p < 0.001) cases. Multivariable Cox regression analysis indicated no differences in persistent airway intrusion requiring reoperation between primary and secondary tracheopexy adjusting for imbalances in age and EA type (p = 0.67). Conclusion Posterior tracheopexy is effective in treating severe tracheomalacia with significant improvements in clinical symptoms and degree of airway collapse on bronchoscopy. With no significant differences in outcomes between primary and secondary treatment, posterior tracheopexy should be selectively considered at the time of initial EA repair.

Abstract
PURPOSE In severe tracheomalacia, aortopexy addresses anterior vascular compression, but does not directly address posterior membranous tracheal intrusion. We review patient outcomes of posterior tracheopexy for tracheomalacia with posterior intrusion to determine if there were resolution of clinical symptoms and bronchoscopic evidence of improvement in airway collapse. METHODS All patients who underwent posterior tracheopexy from October 2012 to March 2016 were retrospectively reviewed. Clinical symptoms, tracheomalacia scores based on standardized dynamic airway evaluation by anatomical region, and persistent airway intrusion were collected. Data were analyzed by Wald and Wilcoxon signed-ranks tests. RESULTS 98 patients (51% male) underwent posterior tracheopexy at a median age of 15months (IQR 6-33months). Median follow-up was 5months (range 0.25-36months). There were statistically significant improvements in clinical symptoms postoperatively, including cough, noisy breathing, prolonged and recurrent respiratory infections, transient respiratory distress requiring positive pressure, oxygen dependence, blue spells, and apparent life-threatening events (p<0.001), as well as ventilator dependence (p=0.04). Tracheomalacia scores on bronchoscopy improved significantly in all regions of the trachea and bronchi (p<0.001). 9.2% had persistent airway intrusion requiring reoperation, usually with aortopexy. CONCLUSIONS Posterior tracheopexy is effective in treating severe tracheomalacia with significant improvements in clinical symptoms and degree of airway collapse on bronchoscopy. LEVEL OF EVIDENCE Level III, treatment study.

Abstract
The management of long-gap esophageal atresia remains challenging with limited consensus on the definition, evaluation, and surgical approach to treatment. Efforts to preserve the native esophagus have been successful with delayed primary anastomosis and tension-based esophageal growth induction processes. Esophageal replacement is necessary in a minority of cases, with the conduit of choice and patient outcomes largely dependent on institutional expertise. Given the complexity of this patient population with significant morbidity, treatment and long-term follow-up are best done in multidisciplinary esophageal and airway treatment centers.

Abstract
PURPOSE Recurrent trachea-esophageal fistula (recTEF) is a frequent (5%-10%) complication of congenital TEF (conTEF) and esophageal atresia (EA) repair. In addition, postoperative acquired TEF (acqTEF) can occur in addition to or even in the absence of prior conTEF in the setting of esophageal anastomotic complications. Reliable repair often proves difficult by endoluminal or standard surgical techniques. We present the results of an approach that reliably identifies the TEF and facilitates airway closure as well as repair of associated tracheal and esophageal problems. METHODS Retrospective review of 66 consecutive patients 2009-2016 (55 referrals and 11 local) who underwent repair via reoperative thoracotomy or cervicotomy for recTEF and acqTEF (IRB P00004344). Our surgical approach used complete separation of the airway and esophagus, which reliably revealed the TEF (without need for cannulation) and freed the tissues for primary closure of the trachea and frequently resection of the tracheal diverticulum. For associated esophageal strictures, stricturoplasty or resection was performed. Separation of the suture lines by rotational pexy of the both esophagus and the trachea, and/or tissue interposition were used to further inhibit re-recurrence. For associated severe tracheomalacia, posterior tracheopexy to the anterior spinal ligament was utilized. RESULTS The TEFs were recurrent (77%), acquired from esophageal leaks (26%), in addition to persistent or missed H-type (6%). Seven patients in this series had multiple TEFs of more than one category. Of the acqTEF cases, 6 were esophagobronchial, 10 esophagopulmonic, 2 esophagotracheal (initial pure EA cases), and 2 from a gastric conduit to the trachea. Upon referral, 18 patients had failed endoluminal treatments; and open operations for recTEF had failed in 18 patients. Significant pulmonary symptoms were present in all. During repairs, 58% were found to have a large tracheal diverticulum, and 51% had posterior tracheopexy for significant tracheomalacia. For larger esophageal defects, 32% were treated by stricturoplasty and 37% by segmental resection. Rotational pexy of the trachea and/or esophagus was utilized in 62% of cases to achieve optimal suture line separation. Review with a mean follow-up of 35months identified no recurrences, and resolution of pulmonary symptoms in all. Stricture treatment required postoperative dilations in 30, and esophageal replacement in 6 for long strictures. There was one death. CONCLUSION This retrospective review of 66 patients with postoperative recurrent and acquired TEF following esophageal atresia repair is the largest such series to date and provides a new categorization for postoperative TEF that helps clarify the diagnostic and therapeutic challenges for management.

Abstract
BACKGROUND Long-gap esophageal atresia (LGEA) may have clinical and syndromic presentations different from those of esophageal atresia (EA) that affects shorter segments of the esophagus (non-LGEA). This may suggest unique underlying developmental mechanisms. OBJECTIVES We sought to characterize clinical differences between LGEA and non-LGEA by carefully phenotyping a cohort of EA patients, and furthermore to assess molecular genetic findings in a subset of them. METHODS This is a retrospective cohort study to systematically evaluate clinical and genetic findings in EA infants who presented at our institution over a period of 10 years (2005-2015). RESULTS Two hundred twenty-nine EA patients were identified, 69 (30%) of whom had LGEA. Tracheoesophageal fistula was present in most non-LGEA patients (158 of 160) but in only 30% of LGEA patients. The VACTERL association was more commonly seen with non-LGEA compared to LGEA (70 vs. 25%; p < 0.001). Further, trisomy 21 was more common in LGEA than in non-LGEA. 25% of LGEA patients had an isolated EA diagnosis without other anomalies, compared to <1% for non-LGEA. Chromosomal microarray analysis showed copy number variations (CNV) in 4 of 39 non-LGEA patients and 0 of 3 LGEA patients. A review of the ClinGen database showed that none of those CNV have been previously described with EA. CONCLUSIONS LGEA represents a unique type of EA. Compared to non-LGEA, it is more likely to be an isolated defect and associated with trisomy 21. Further, it is less commonly seen with VACTERL anomalies. Our findings suggest the involvement of unique pathways that may be distinct from those causing non-LGEA.

Abstract
Early brain development is characterized by rapid growth and perpetual reconfiguration, driven by a dynamic milieu of heterogeneous processes. Postnatal brain plasticity is associated with increased vulnerability to environmental stimuli. However, little is known regarding the ontogeny and temporal manifestations of inter- and intra-regional functional connectivity that comprise functional brain networks. Resting-state functional magnetic resonance imaging (rs-fMRI) has emerged as a promising non-invasive neuroinvestigative tool, measuring spontaneous fluctuations in blood oxygen level dependent (BOLD) signal at rest that reflect baseline neuronal activity. Over the past decade, its application has expanded to infant populations providing unprecedented insight into functional organization of the developing brain, as well as early biomarkers of abnormal states. However, many methodological issues of rs-fMRI analysis need to be resolved prior to standardization of the technique to infant populations. As a primary goal, this methodological manuscript will (1) present a robust methodological protocol to extract and assess resting-state networks in early infancy using independent component analysis (ICA), such that investigators without previous knowledge in the field can implement the analysis and reliably obtain viable results consistent with previous literature; (2) review the current methodological challenges and ethical considerations associated with emerging field of infant rs-fMRI analysis; and (3) discuss the significance of rs-fMRI application in infants for future investigations of neurodevelopment in the context of early life stressors and pathological processes. The overarching goal is to catalyze efforts toward development of robust, infant-specific acquisition, and preprocessing pipelines, as well as promote greater transparency by researchers regarding methods used.

Abstract
PURPOSE Patients with long-gap esophageal atresia (LGEA) treated with the Foker process are at increased risk of venous thromboembolism (VTE). An institutional quality improvement program to decrease VTE risk factor exposure and utilize prophylactic anticoagulation was implemented. We aim to evaluate the efficacy and safety of a VTE risk-reduction program in patients with LGEA. METHODS Implementation and evaluation of a VTE risk-reduction program in patients with LGEA from 2012 to 2015 was performed. Symptomatic VTE with radiographic confirmation were defined as events. Post-program characteristics were evaluated and compared to a historical cohort. RESULTS Sixty-seven patients were identified. Two developed VTE (7 %) post-program implementation; compared to 13/40 (33 %) VTE incidence in the historical cohort (p = 0.018). Baseline demographics were similar, including age, esophageal atresia type and gap length. Post-protocol patients had fewer paralysis episodes (p = 0.004), paralysis days (p = 0.003), central venous catheters (p = 0.003), thoracotomies (p < 0.001), ventilator hours (p = 0.02), and decreased hospital (p < 0.001) and ICU stay (p < 0.001). All patients in the VTE risk-reduction program were exposed to prophylactic anticoagulation. No bleeding complications and/or thrombosis-related mortality occurred. CONCLUSION VTE risk-reduction program implementation decreased symptomatic VTE incidence with associated decreases in ICU and hospital length of stay. Prophylactic anticoagulation can be utilized safely in a complicated pediatric surgical population.

Abstract
Tracheobronchomalacia, as a whole, is likely misdiagnosed and underestimated as a cause of respiratory compromise in pediatric patients. Currently, there is no standardized approach for the overall evaluation of pediatric tracheobronchomalacia (TBM) and the concept of excessive dynamic airway collapse (EDAC); no grading score for the evaluation of severity; nor a standardized means to successfully approach TBM and EDAC. This paper describes our experience standardizing the approach to these complex patients whose backgrounds include different disease etiologies, as well as a variety of comorbid conditions. Preoperative and postoperative evaluation of patients with severe TBM and EDAC, as well as concurrent development of a prospective grading scale, has allowed us to ascertain correlation between surgery, symptoms, and effectiveness on particular tracheal-bronchial segments. Long-term, continued collection of patient characteristics, surgical technique, complications, and outcomes must be collected given the overall heterogeneity of this particular population.

Abstract
Tracheomalacia (TM) is defined as an increased collapsibility of the trachea due to structural anomalies of the tracheal cartilage and/or posterior membrane. Tracheomalacia has a wide range of etiologies but is most commonly present in children born with esophageal atresia and tracheal esophageal fistula. Clinical symptoms can range from minor expiratory stridor with typical barking cough to severe respiratory distress episodes to acute life-threatening events (ALTE). Although the majority of children have mild-to-moderate symptoms and will not need surgical intervention, some will need life-changing surgical treatment. This article examines the published pediatric literature on TM, discusses the details of clinical presentation, evaluation, diagnosis, and a variety of treatments.

Abstract
PURPOSE To identify factors associated with an increased risk of fractures in Long-Gap Esophageal Atresia (LGEA) patients. Following implementation of a risk-stratified program, we hypothesized a reduction in fracture incidence within this potentially high-risk population. METHODS A retrospective review of LGEA-patients admitted between 2005 and 2014 was conducted. Symptomatic fractures with radiographic confirmation were defined as events. Univariate and multivariable analysis evaluated factors including admission weight-for-age z-score, primary versus secondary Foker process (FP), weight at Foker Stage I, days and episodes of paralysis, number of parenteral nutrition (PN) days, cumulative dose of loop diuretics adjusted for body weight and days exposed, and exposure to non-loop diuretics. A fracture-prevention protocol was initiated in 2012; incidence was evaluated pre and post-intervention. RESULTS Fifty-nine patients met inclusion criteria. Twenty-three (39%) patients in the entire cohort incurred at least one fracture during their hospitalization utilizing the Foker process. Given this high percentage, a targeted fracture-prevention protocol was initiated in 2012. Fracture incidence decreased from 48% prior to the protocol to 21% following the protocol (P = 0.046). Several variables that were associated with an increased risk of fractures on univariate analysis included prior esophageal anastomosis attempt (P = 0.008), number of separate episodes of paralysis (P = 0.002), exposure to non-loop diuretics (P = 0.006), cumulative loop diuretic dose (P < 0.001), as well as cumulative loop diuretic over days exposed (P < 0.001). Intensive care unit (ICU) stay (P = 0.002) and total length of hospitalization (P < 0.001) were also significantly longer among patients with a fracture. Number of separate episodes of paralysis was the only independent risk factor for the development of a fracture; patients having more than 3 episodes of paralysis had an estimated risk of fracture 15 times higher than those patients paralyzed only once or twice (O.R. 15.87, 95% C.I.: 1.47-171.23, P = 0.008). CONCLUSION Episodes of paralysis appeared to be the most significant risk factor for fractures in patients with LGEA who underwent the Foker procedure. The incidence of symptomatic fractures decreased significantly following implementation of a standardized protocol in this series of LGEA patients with continued prospective evaluation.

Abstract
BACKGROUND Infants with long-gap esophageal atresia (LGEA) undergo repeated thoracotomies for staged surgical repair known as the Foker process (FP). Associated prolonged mechanical ventilation results in exposure to high doses of opioids and benzodiazepines, and prolonged weaning times and ICU stays. AIM The aim of this study was to determine the effectiveness of short-term paravertebral nerve block (PVNB) catheters in reducing opioid/benzodiazepine exposure and effects on clinical variables. METHODS The medical records of seventeen infants were retrospectively reviewed; 11 with PVNB and six without (CG). PVNB were placed using ultrasound-guidance and chloroprocaine infusions implemented in the ICU. Opioids and benzodiazepines were administered via the protocol for 5 days following thoracotomies for Foker-I and Foker-II. RESULTS Foker-I: Average reduction in morphine and midazolam consumption was 36% (2.18 vs 3.40 mg·kg(-1) ·day(-1) ; P < 0.001) and 31% (2.25 vs 3.25 mg·kg(-1) ·day(-1) ; P = 0.033), respectively, in the PVNB compared with CG. Foker-II: Average reduction in morphine and midazolam consumption was 39% (3.19 vs 5.27 mg·kg(-1) ·day(-1) ) and 38% (3.46 mg·kg(-1) ·day(-1) vs 5.62; P < 0.001), respectively in the PVNB compared with CG. 24-h prior to extubation: Average reduction in morphine and midazolam consumption was 50% (2.91 vs 5.85 mg·kg(-1) ·24 h(-1) ; p = 0.023) and 61% (2.27 vs 5.83 mg·kg(-1) ·24 h(-1) ; P = 0.004), respectively, in the PVNB compared with CG. Infusion wean time, (independence from opioid/midazolam infusions) following extubation was 5 days in the PVNB group and 15 days in CG (P = 0.005). Median ICU stay (IQR) was 40 days (34-45 days) in PVNB patients and 71 days (42-106 days) in controls (P = 0.02). PVNB catheters were left an average of 7 days and there were no complications associated with the nerve blocks. CONCLUSION Short-term PVNB placement decreases opioid and benzodiazepine exposure, weaning days and ICU stay in infants undergoing prolonged mechanical ventilation for LGEA repair in this small pilot study. Larger studies are warranted to confirm results.

Abstract
PURPOSE Tracheobronchomalacia (TBM) is associated with esophageal atresia, tracheoesophageal fistulas, and congenital heart disease. TBM results in chronic cough, poor mucous clearance, and recurrent pneumonias. Apparent life-threatening events or recurrent pneumonias may require surgery. TBM is commonly treated with an aortopexy, which indirectly elevates trachea's anterior wall. However, malformed tracheal cartilage and posterior tracheal membrane intrusion may limit its effectiveness. This study describes patient outcomes undergoing direct tracheobronchopexy for TBM. METHODS The records of patients that underwent direct tracheobronchopexy at our institution from January 2011 to April 2014 were retrospectively reviewed. Primary outcomes included TBM recurrence and resolution of the primary symptoms. Data were analyzed by McNemar's test for matched binary pairs and logistic regression modeling to account for the endoscopic presence of luminal narrowing over multiple time points per patient. RESULTS Twenty patients were identified. Preoperative evaluation guided the type of tracheobronchopexy. 30% had isolated anterior and 50% isolated posterior tracheobronchopexies, while 20% had both. Follow-up was 5 months (range, 0.5-38). No patients had postoperative ALTEs, and pneumonias were significantly decreased (p=0.0005). Fewer patients had tracheobronchial collapse at postoperative endoscopic exam in these anatomical regions: middle trachea (p=0.01), lower trachea (p<0.001), and right bronchus (p=0.04). CONCLUSION The use of direct tracheobronchopexy resulted in ALTE resolution and reduction of recurrent pneumonias in our patients. TBM was also reduced in the middle and lower trachea and right mainstem bronchus. Given the heterogeneity of our population, further studies are needed to ascertain longer-term outcomes and a grading scale for TBM severity.

Abstract
The Foker process is a method of esophageal lengthening through axial tension-induced growth, allowing for subsequent primary reconstruction of the esophagus in esophageal atresia (EA). In this unique case, the Foker process was used to grow the remaining esophageal segment long enough to attain esophageal continuity following failed colonic interpositions for long-gap esophageal atresia (LGEA). Initially developed for the treatment of LGEA in neonates, this case demonstrates that (i) an active esophageal lengthening response may still be present beyond the neonate time-period; and, (ii) the Foker process can be used to restore esophageal continuity following a failed colonic interposition if the lower esophageal segment is still present.

Abstract
BACKGROUND We investigated whether removable stents, such as self-expandable plastic stents (SEPSs) and fully covered self-expandable metal stents (FCSEMSs) could provide an alternative treatment for recalcitrant strictures and esophageal perforations after esophageal atresia (EA) repair. OBJECTIVE The primary aim of our study was to evaluate technical feasibility. Secondary aims were to evaluate safety and procedural success. DESIGN Retrospective study. SETTING Tertiary-care referral center. PATIENTS A total of 24 children with EA. INTERVENTIONS Retrospective review of all children with EA who underwent dilation and esophageal stent placement from January 2010 to February 2013 at our institution. MAIN OUTCOME MEASUREMENTS Healing of perforation and stricture resolution at 30 and 90 days. RESULTS A total of 41 stents (SEPSs 14, FCSEMSs 27) were placed in 24 patients with EA during the study period, including 14 who had developed esophageal leaks. Procedural success of esophageal stent placement in the treatment of refractory strictures was 39% at 30 days and 26% at 90 days. The success rate was 80% for closure of esophageal perforations with stent therapy after dilation and 25% for perforations associated with surgical repair. Adverse events of stent placement included migration (21% of SEPSs and 7% of FCSEMSs), granulation tissue (37% of FCSEMSs), and deep ulcerations (22% of FCSEMSs). LIMITATIONS Retrospective study with small sample size. CONCLUSION SEPSs and FCSEMSs can be placed successfully in small infants and children with a history of EA repair. The stents appear to be safe and beneficial in closing esophageal perforations, especially post-dilation. However, a high stricture recurrence rate after stent removal may limit their usefulness in treating recalcitrant esophageal anastomotic strictures.
