Introduction: Tracheomalacia severity is difficult to quantify, however, ultrashort echo-time MRI objectively quantifies tracheomalacia in infants without sedation, radiation, or intubation. Patients with tracheoesophageal fistula and esophageal atresia (TEF/EA) commonly have tracheomalacia, however, the relationship between tracheomalacia severity and esophageal atresia has not been well defined. The primary objective of this study was to establish the relationship between EA and tracheomalacia severity and identify possible predictors of tracheomalacia severity., Methods: A retrospective review of neonates with TEF/EA who had previously undergone UTE MRI was performed. The trachea was divided into thirds. Maximal eccentricity in each third was calculated by measuring the anterior posterior dimension (MinD) and dividing it by the maximum width of the trachea (MaxD). Frequency of respiratory related admissions, number of upper respiratory infections, and number of steroids courses were quantified in addition to eccentricity in short and long gap esophageal atresia patients., Results: A total of 16 TEF/EA patients were included. Patients with long gap esophageal atresia had more severe tracheomalacia than short gap as measured by eccentricity in the upper (0.60 vs 0.72, p = 0.03), middle (0.48 vs 0.61, p = 0.02), and lower (0.5 vs 0.65, p = 0.01) trachea. Long gap esophageal atresia patients had more frequent respiratory readmissions (1.87 admissions/year vs 0.54 admissions/year) (p = 0.03). Following TEF/EA repair the trachea was less eccentric in the upper third (0.64 pre, 0.79 post, p < 0.01) and more eccentric in the lower third (0.69 pre, 0.56 post, p < 0.01)., Conclusion: Differences in esophageal gap and repair status correlate with airway eccentricity and tracheomalacia symptoms., Competing Interests: Conflicts of interest None., (Copyright © 2024 Elsevier Inc.

Introduction: Esophageal atresia/tracheoesophageal fistula (EA/TEF) is a congenital malformation that occurs in about 1 in 2500-4000 live births. After surgical repair, despite the lack of evidence supporting the routine use of postoperative esophagram, most surgeons report obtaining an esophagram prior to enteral feeding. We hypothesized that abnormal indicators in vital signs, drain characteristics, and chest radiograph (CXR) could be used to screen for anastomotic leak, thus reducing the need for a routine esophagram., Methods: A single institution, retrospective chart review of all patients born with EA with or without TEF between 2009 and 2022 was performed. Vital signs, postoperative CXR, chest drain characteristics, and esophagram results were analyzed for patients who underwent repair., Results: Forty-five patients who underwent EA/TEF repair were included in the study, and 40 patients had routine esophagram. Out of the twenty-two patients who had at least one abnormal indicator, 14 (64%) had an anastomotic leak. Seventeen patients (43%) had the absence of abnormalities of all three indicators, and none of these patients had an anastomotic leak (100% negative predictive value). Moreover, changes in drain characteristics and vital signs together presented high sensitivity (87.5%), specificity (90%), and negative predictive value (94%)., Conclusions: In the absence of abnormalities in vital signs, CXR, and drain characteristics in patients undergoing EA/TEF repair, routine esophagram can be safely avoided prior to enteral feeding. Abnormalities in drain characteristics and vital signs together were highly sensitive and specific for anastomotic leak, thus potentially eliminating the need for routine CXR and thereby minimizing radiation exposure and cost., (Copyright © 2024.

We report successful surgical management of post-intubation tracheoesophageal fistula (TEF) in an adult patient requiring long-term mechanical ventilation. A complete tracheal transection without tracheal resection, via an anterior cervical approach, followed by direct closure of tracheal and esophageal defect, and interposition of muscle flap between the suture lines and tracheal reconstruction was performed. In selected cases, this surgical procedure may be a viable alternative to traditional techniques used to treat post-intubation TEF via the anterior or lateral cervical approach.

Introduction: There is currently no validated diagnostic modality to characterize the anatomy and predict outcomes of tracheal esophageal defects, such as esophageal atresia (EA) and tracheal esophageal fistulas (TEFs). We hypothesized that ultra-short echo-time MRI would provide enhanced anatomic information allowing for evaluation of specific EA/TEF anatomy and identification of risk factors that predict outcome in infants with EA/TEF., Methods: In this observational study, 11 infants had pre-repair ultra-short echo-time MRI of the chest completed. Esophageal size was measured at the widest point distal to the epiglottis and proximal to the carina. Angle of tracheal deviation was measured by identifying the initial point of deviation and the farthest lateral point proximal to the carina., Results: Infants without a proximal TEF had a larger proximal esophageal diameter (13.5 ± 5.1 mm vs. 6.8 ± 2.1 mm, p = 0.07) when compared to infants with a proximal TEF. The angle of tracheal deviation in infants without a proximal TEF was larger than infants with a proximal TEF (16.1 ± 6.1° vs. 8.2 ± 5.4°, p = 0.09) and controls (16.1 ± 6.1° vs. 8.0 ± 3.1°, p = 0.005). An increase in the angle of tracheal deviation was positively correlated with duration of post-operative mechanical ventilation (Pearson r = 0.83, p < 0.002) and total duration of post-operative respiratory support (Pearson r = 0.80, p = 0.004)., Discussion: These results demonstrate that infants without a proximal TEF have a larger proximal esophagus and a greater angle of tracheal deviation which is directly correlated with the need for longer post-operative respiratory support. Additionally, these results demonstrate that MRI is a useful tool to assess the anatomy of EA/TEF., (© 2023 S. Karger AG, Basel.)

Purpose: Antenatal detection of limb anomalies is not uncommon, and pregnancies are usually terminated in view of the expected physical handicap. The aim of this retrospective observational study is to delineate the spectrum of fetal limb anomalies and provide evidence in support of complete postnatal evaluation in establishing recurrence risk., Methods: We present 54 cases of limb malformations detected antenatally and discuss the spectrum of abnormalities, the utility of fetal autopsy, and genetic testing to establish recurrence risk in subsequent pregnancies., Results: 16/54 cases were isolated radial ray anomalies. There were five cases of amniotic band syndrome, five limb body wall complex cases, three VACTERL (vertebral defects, anal atresia, cardiac defects, tracheo-esophageal fistula, renal anomalies, and limb abnormalities) associations, one case of sirenomelia, two cases of limb pelvis hypoplasia, and one case of OEIS (Omphalocele Exstrophy Imperforate anus and spinal defects). Four fetuses with non-isolated radial ray anomaly had trisomy 18. One case with bilateral radial ray defect had a mutation in the FANC-E gene confirming fanconi anemia. Twelve cases were unclassified., Conclusion: Autopsy is the most important investigation in fetuses with limb anomalies. We suggest chromosomal microarray (CMA) as a first-tier test after autopsy. However, in cases of bilaterally symmetrical limb anomalies, in case of previous similarly affected child, or history of consanguinity, whole exome sequencing (WES) can be offered as the primary investigation, followed by CMA if WES is normal., (© 2022 Wiley Periodicals LLC.)

We present a case of surgical management of a tracheoesophageal fistula (TEF) following prolonged intubation. After transverse tracheal division and retraction of the distal stump, direct closure of the esophageal defect and repair of the membranous tracheal defect using a synthetic bioabsorbable patch were performed, followed by interposition of muscle flap between the suture lines and tracheal reconstruction. Large TEFs, without tracheal stenosis or circumferential airway defect, associated with marked peritracheal inflammation, may be treated with this alternative tracheoplastic technique in patients deemed not suitable for tracheal resection and anastomosis.

Background: Esophageal atresia is a major anomaly of varying severity. The complexity of surgical correction depends on the presence of a distal fistula., Objective: This study aimed to determine the feasibility and accuracy of prenatal ultrasound detection of the distal fistula in fetuses diagnosed with esophageal atresia., Study Design: This was an observational study conducted at a single tertiary care center between 2019 and 2021. Included were pregnant patients carrying a fetus prenatally diagnosed with esophageal atresia that was confirmed postnatally during corrective surgery or at postmortem autopsy. During the scan, the performing investigator determined the presence or absence of a distal fistula by scanning the location of the lower esophagus during fetal breathing. Cases in which the lower esophagus was observed distending with amniotic fluid during breathing were deemed "fistula present," and the remaining cases "fistula absent." Test feasibility and performance indices, including sensitivity, specificity, and positive and negative predictive value were calculated. The offline clips and images were reviewed by 2 investigators for the assessment of interoperator agreement using Cohen's Kappa formula., Results: Included were 16 fetuses with esophageal atresia scanned between 2019 and 2021. All fetuses were successfully scanned with sufficient resolution of the area of interest during at least 3 cycles of breathing. It took a median of 8.5 minutes to determine the presence or absence of a distal fistula. The feasibility of the test was 100% (16/16). The test's sensitivity, specificity, and positive and negative predictive values were 80% (95% confidence interval, 55-100), 100% (95% confidence interval, 60-100), 100% (95% confidence interval, 65-100), and 75% (95% confidence interval, 45-100), respectively. The Cohen's Kappa for interoperator agreement was calculated to be 1, P<.001, corresponding to a "perfect" level of agreement., Conclusion: Distal fistulas in esophageal atresia can be demonstrated prenatally by targeted scanning using appropriate technique. The method provided is feasible, reproducible, and has excellent performance indices. This novel technique and observations may improve the prenatal diagnosis and counseling of esophageal atresia., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Introduction: Infants with esophageal atresia and/or tracheoesophageal fistula (EA/TEF) undergo screening for tethered cord syndrome (TCS) via ultrasound and magnetic resonance imaging. Existing literature lacks data to guide optimal timing of screening and magnetic resonance imaging (MRI) is often delayed until 3-6 mo of age, when it is frequently forgotten. Detethering surgery has a high rate of success in patients with TCS and is often performed prophylactically due to potential irreversible deficits. This study aims to improve screening procedure for infants with EA/TEF., Methods: A retrospective chart review was done of all EA/TEF patients treated over 6 y (n = 79). The study examined how often each imaging modality was performed and identified a TCS lesion, as well as age of screening/surgical intervention., Results: Screening for TCS was done with MRI 58% of the time and US 15% of the time. However, 38% of patients did not undergo any screening. Out of the patients with TCS on MRI (n = 19, 41.3%), 73.7% had neurosurgery. Of patients who underwent ultrasound (US) (n = 12), nine patients also had MRI later: two reported TCS lesions and subsequently had neurosurgery. Surgical infection rates and complications were 0/14., Conclusions: MRI demonstrated a higher rate of detecting TCS lesions than US, and patients with TCS frequently had detethering. Patients with ≥3 VACTERL or vertebral anomalies had a higher incidence of TCS on MRI. Patients with vertebral anomalies reported false negative ultrasounds in two cases, suggesting the potential superiority of MRI screening in this subgroup. A third of children did not undergo any imaging and this will require a process improvement., (Copyright © 2022 Elsevier Inc. All rights reserved.)

This is the first report describing successful visualisation of a tracheo-oesophageal fistula (TEF) based on fluid flow on prenatal foetal ultrasonography. At 36 weeks of gestation, an anechoic tubular structure with a strong blue-coloured stream of fluid flow was observed extending from the trachea towards the gastric bubble on prenatal ultrasonography. TEF can be visualised prenatally under certain conditions.

Revision surgery for the complications after repair of esophageal atresia is often complex because of previous surgeries and chest infections and thus requires surgical expertise. This study describes surgical experiences with the use of indocyanine green (ICG) fluorescence imaging localization-assisted thoracoscopy during revision surgery, including recurrent tracheoesophageal fistula (rTEF) (8 cases, one of which was esophageal-pulmonary fistula) and delayed esophageal closure (1 case). We performed fistula repair and esophageal reconstruction according to the indications of ICG. The application of this method avoids the excessive trauma caused by freeing the trachea and esophagus. Contrast imaging taken one week and one month after surgery indicated no spillover of the contrast agent from the esophagus, except in 1 case. Indocyanine green fluorescence imaging localization-assisted thoracoscopy is worth promoting for revision surgery after esophageal atresia repair., (© 2022. The Author(s).)

This case study presents an infant with non-specific symptoms for esophageal atresia and tracheoesophageal fistula shortly after birth. A detailed examination of the infant provides clues to the potential diagnosis while the radiograph provides confirmation. This column provides the clinician with a detailed evaluation of the x-ray findings specific to the infant with esophageal atresia with and without tracheo esophageal fistula. Additionally, a description of the different types of this congenital anomaly, embryology, pathophysiology, testing, treatment, and nursing considerations is presented., (© Copyright 2022 Springer Publishing Company, LLC.)

The goal of this paper was to report a new variant of oesophageal atresia: an H-type congenital tracheo-oesophageal fistula associated with oesophageal segmental stenosis distal to the fistula. Although symptoms were present from birth, we did not differentiate the new anatomical variant preoperatively. The patient was treated by fistula ligation, segmental resection of the distal oesophagus and end-to-end anastomosis of the oesophagus by thoracoscopic surgery. Here we describe the clinical history and management of the newborn infant, together with diagnostic recommendations to prevent misdiagnosis in the management of this condition., (© The Author(s) 2021.

Devices originally designed for closure of cardiac septal defects have also been proposed for the treatment of acquired tracheo-oesophageal fistula (TOF). Choosing the right occluder device to match TOF size and shape is essential for a tailored treatment. We report the successful endoscopic closure of a post-radiotherapy TOF using preprocedural CT scan with holographic three-dimensional reconstruction and an Amplatzer atrial septal device. Complete TOF sealing was achieved with resolution of respiratory symptoms, and the patient was maintaining his ability to eat at 4-month follow-up., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2022.

Objective: Oesophageal atresia (OA) is a major anomaly of varying severity. The complexity of surgical correction highly depends on the gap length of missing oesophagus and the presence of a distal fistula. The aim of this study was to identify antenatal sonographic findings associated with presence of a distal fistula and type of surgical repair METHODS: Prenatal medical records of neonates postnatally diagnosed with OA were reviewed. Sonographic signs of OA (small/absent stomach, polyhydramnios, oesophageal pouch) and the trimester at sign detection were recorded and compared between (1) OA with and without a distal fistula and (2) early one-step versus delayed two-step anastomosis. Multivariate analysis was performed., Results: Overall, 80 cases of OA were included. Absence of a distal fistula was significantly associated with higher rates of small/absent stomach (100% vs 28.6%, P<0.0001), oesophageal pouch (100% vs 24.3%, P<0.0001) and severe polyhydramnios (66.7% vs 22.9%, P=0.006), compared with OA with a distal fistula.Cases requiring a delayed two-step repair had higher rates of small/absent stomach (84.2% vs 16.7%, P>0.0001), severe polyhydramnios (47.4% vs 16.7%, P=0.008) and oesophageal pouch (73.7% vs 18.5%, P<0.0001), compared with those corrected in an early one-step anastomosis.Multivariate logistic regression found small/absent stomach and pouch to be significantly and independently associated with a delayed two-step anastomosis., Conclusion: OA without a distal fistula is associated with higher rates of prenatal sonographic signs. Both small/absent stomach and a pouch are independently associated with a delayed two-step anastomosis. These findings may help improve antenatal parental counselling regarding the anticipated surgical repair., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Rationale: Congenital tracheoesophageal fistula (TEF) is a rare developmental malformation. The H subtype accounts for approximately 4% of TEFs. Unlike other TEFs, the H-type is not accompanied by esophageal atresia and has nonspecific clinical symptoms, and its specific anatomical abnormalities are not always readily apparent. Furthermore, none of the currently available diagnostic methods for H-type TEF have absolute sensitivity, resulting in misdiagnoses, and accurate diagnoses are often delayed even until adulthood; in our case, we detected a congenital bronchoesophageal fistula, which is even more rare than regular H-type TEF, through a technique that was not previously reported for newborns, involving bronchoscopy, with methylene blue injected through an esophagoscope. We believe that we have provided this kind of case first in newborns.Furthermore, because there is not one literature summarizing the clinical symptoms and the effective methods up to now, we still are not clear which detective method is more efficient or accurate, especially in newborns, so it is very necessary to summarize and compare for improving the early diagnosis of TEFs; our study makes a significant contribution to the literature because we collated previously reported cases, including the clinical features and the usefulness and success rates of major tests, which will be very helpful for the early diagnosis of TEFs., Patient Concerns: A newborn male presented with an array of nonspecific clinical symptoms from birth, leading to pneumonia and mechanical ventilation. Oral feeding led to an improvement in most but not all symptoms, which returned when oral feeding was resumed. A second round of confirmatory tests was still unable to detect the cause., Diagnosis: The diagnosis of H-type bronchoesophageal fistula was established through a technique that was not previously reported for newborns, involving bronchoscopy, with methylene blue injected through an esophagoscope., Interventions: The surgery was performed after diagnosis, and the bronchoesophageal fistula was successfully repaired., Outcomes: The patient was discharged on postoperative day 7, and his status was reported to be normal at a follow-up visit 8 months after surgery., Lessons: H-type TEF is a rare congenital abnormality, and its early diagnosis is highly difficult, especially bronchoesophageal fistula. Increased oral saliva and air-filled stomachs are characteristic manifestations. Bronchoscopy combined with esophagoscopy can improve the rate of early diagnosis. A combination of tests can improve the detection rate., Competing Interests: The authors have no conflicts of interests to disclose., (Copyright © 2022 the Author(s).

Congenital esophageal web is a very rare type of esophageal atresia (EA) and is considered as Type IV atresia in Kluth's classification. Type IV EA is further classified into subgroups according to the location of web and the presence of tracheoesophageal fistula (TEF). Herein, we present a newborn having Type IV 1a EA who was initially suspected as isolated EA and has co-existing malrotation together with the review of the literature. A newborn having congenital esophageal web was admitted with antenatal ultrasonography revealing polyhydramnios, dilated stomach, and duodenum. Abdominal X-ray revealed a gasless abdomen suggesting isolated EA. The upper gastrointestinal series confirmed complete obstruction at the lower esophagus. Bronchoscopy performed excluding TEF. Laparotomy revealed intestinal malrotation and the absence of another GI webs. Gastrotomy was performed and mucosal web at GEJ was seen by pushing nasogastric catheter. Web excision and Ladd procedure were performed. Congenital esophageal web is an extremely rare type of esophageal anomaly that can be only classified in Kluth classification. A high index of suspicion is required for diagnosis especially in newborns with the gasless abdomen and esophageal obstruction at the level of GEJ. Preoperative bronchoscopy is mandatory to exclude an associating TEF. Surgical exploration via laparotomy is beneficial for exploring additional GIS anomalies., (© 2021 Japanese Teratology Society.)

Purpose: Despite improvements of diagnosis and management, acquired benign tracheoesophageal fistulas (AB-TEFs) remain a challenging clinical problem and a life-threating condition. In the present study, we reviewed the early results and the long-term outcomes after surgical treatment of cervical AB-TEFs treated in our institution during the last 9 years., Methods: This retrospective study included patients who underwent transcervical repair of benign cervical AB-TEFs. Patients were identified from a prospectively filled electronic database which included patients' demographics, medical history, disease presentation, prior treatments, operative report, morbidity and mortality, hospital stay, postoperative results and follow-up information., Results: A total of 13 patients affected by cervical AB-TEF were treated. Most of the patients (91%) in our series were treated with a lateral cervicotomic approach with interposition of either sternocleidomastoid muscle flap (72.7%) or pectoralis major myocutaneous flap (9.1%) or infrahyoid muscle flap (9.1%). The univariate analysis of showed that the etiology and surgical technique were significantly associated with immediate postoperative outcome. Esophageal diversion was removed in all patients but 3 due to their neurological status, which was the only significant factor related to post-operative oral-intake (p =0.016). We experienced 2 (18.2%) failures of the reconstruction, which occurred in patients previously treated with chemoradiation for head and neck malignancies. None of the remaining patients (72.8%) relapsed after a long-term follow-up restoring a normal oral diet was restored., Conclusion: The lateral cervicotomic approach with sternocleidomastoid flap interposition showed its effectiveness and safety in the treatment of AB-TEFs in our single-institution experience., (Copyright © 2021 Elsevier Inc.

Objectives: Stent migration is a common complication of airway stent placement for upper tracheal stenosis and tracheoesophageal fistula. Although several researchers have reported that external fixation is effective in preventing stent migration, the usefulness and safety of external fixation have not been proved because their cohorts were small. We therefore investigated the efficacy and safety of external fixation during upper tracheal stenting., Methods: Records of patients who underwent airway stent placement from May 2007 to August 2018 in a single centre were retrospectively reviewed. We included only patients whose stent had been placed in the upper trachea with external fixation to the tracheal wall. The primary endpoint of this study was the rate of stent migration., Results: Altogether, 51 procedures were performed in 45 patients (32 males, 13 females; median age 60 years, range 14-91 years). The median follow-up period was 9 months (range 0.3-90 months). Among the procedures, 15 were performed for benign disease and 36 for malignancy. Stents were composed of either silicone (n = 42) or metal (n = 9). Stent migration occurred in 3 (6%) patients. The stents with migration were all composed of silicone. Other sequelae were granulation tissue formation in 10 (20%) patients, sputum obstruction in 6 (12%), cellulitis in 3 (6%) and pneumonia in 1 (2%)., Conclusions: External fixation was an effective method for preventing migration of airway stents placed for upper tracheal stenosis and tracheoesophageal fistula. The complications were acceptable in terms of safety., (© The Author(s) 2021. Published by Oxford University Press on behalf of the European Association for Cardio-Thoracic Surgery.

Objective: Esophageal atresia and/or tracheoesophageal fistula (EA/TEF) remains one of the most frequently missed congenital anomalies prenatally. The aim of our study was to elucidate the sonographic manifestation of EA/TEF throughout pregnancy., Methods: This was a retrospective study of data obtained from a tertiary center over a 12-year period. The prenatal ultrasound scans of fetuses with EA/TEF were assessed to determine the presence and timing of detection of three principal signs: small/absent stomach and worsening polyhydramnios, both of which were considered as 'suspected' EA/TEF, and esophageal pouch, which was considered as 'detected' EA/TEF. We assessed the yield of the early (14-16 weeks' gestation), routine mid-trimester (19-26 weeks) and third-trimester (≥ 27 weeks) anomaly scans in the prenatal diagnosis of EA/TEF., Results: Seventy-five cases of EA/TEF with available ultrasound images were included in the study. A small/absent stomach was detected on the early anomaly scan in 3.6% of fetuses scanned, without a definitive diagnosis. On the mid-trimester scan, 19.4% of scanned cases were suspected and 4.3% were detected. On the third-trimester anomaly scan, 43.9% of scanned cases were suspected and 33.9% were detected. An additional case with an esophageal pouch was detected on magnetic resonance imaging (MRI) in the mid-trimester and a further two were detected on MRI in the third trimester. In total, 44.0% of cases of EA/TEF in our cohort were suspected, 33.3% were detected and 10.7% were suspected but, eventually, not detected prenatally., Conclusions: Prenatal diagnosis of EA/TEF on ultrasound is not feasible before the late second trimester. A small/absent stomach may be visualized as early as 15 weeks' gestation. Polyhydramnios does not develop before the mid-trimester. An esophageal pouch can be detected as early as 22 weeks on a targeted scan in suspected cases. The detection rates of all three signs increase with advancing pregnancy, peaking in the third trimester. The early and mid-trimester anomaly scans perform poorly as a screening and diagnostic test for EA/TEF. © 2020 International Society of Ultrasound in Obstetrics and Gynecology., (© 2020 International Society of Ultrasound in Obstetrics and Gynecology.)

We report the case of a 6-month-old girl who presented with recurrent pneumonia and growth failure. After full examination, she was diagnosed with long-standing, unrecognised tracheal foreign body, which was then successfully removed. However, her chronic respiratory symptoms did not improve, and she also had feeding intolerance. The persistence of symptoms indicated a second bronchoscopy and finally an acquired tracheo-oesophageal fistula was diagnosed. This case emphasises the challenges in diagnosis of an inhaled foreign body in young children. Late diagnosis of this condition can cause significant morbidities. A high index of suspicion and careful investigation are very important to prevent long-term complications., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2021.

Background: Tracheo- or bronchoesophageal fistula (TBF) occurring after esophagectomy represent a rare but devastating complication. Management remains challenging and controversial. Therefore, the purpose of this study was to evaluate the outcome of different treatment approaches and to propose recommendations for the management of TBF., Methods: From 2008 to 2018, 15 patients were treated because of TBF and were analyzed with respect to fistula appearance, treatment strategy (stenting, endoscopic vacuum therapy and/or surgical reintervention) and outcome., Results: In each case, the fistula was small, located close to the tracheal bifurcation and associated simultaneously ( n  = 6, 40%) or metachronously ( n  = 9, 60%) with an anastomotic leakage. Latter was covered by esophageal stents in six patients which in turn resulted in occurrence of TBF at a later time in five patients. Management of TBF included conservative therapy ( n  = 3), stenting ( n  = 6), or suturing ( n  = 6). Ten patients underwent rethoracotomy. Treatment failure was observed in eight patients (53%). In all patients, treatment was accompanied by progressive sepsis. On the contrary, all seven patients with successful defect closure remained in good general condition., Conclusion: Fistula appearance was similar in all patients. Implementation of esophageal stents cannot be recommended because of possibility of TBF at a later time point. Surgery is usually required and should preferably be performed when the patient's condition has been optimized at a single-stage repair. Esophageal diversion can only be recommended in patients with persisting mediastinitis. The key element for successful treatment of TBF, however, is control over sepsis; otherwise, outcome of TBF is devastating., Competing Interests: The authors have no conflict of interest., (Thieme.

Herein, realistic and reusable phantoms for simulation of pediatric lung video-assisted thoracoscopic surgery (VATS) were proposed and evaluated. 3D-printed phantoms for VATS were designed based on chest computed tomography (CT) data of a pediatric patient with esophageal atresia and tracheoesophageal fistula. Models reflecting the patient-specific structure were fabricated based on the CT images. Appropriate reusable design, realistic mechanical properties with various material types, and 3D printers (fused deposition modeling (FDM) and PolyJet printers) were used to represent the realistic anatomical structures. As a result, the phantom printed by PolyJet reflected closer mechanical properties than those of the FDM phantom. Accuracies (mean difference ± 95 confidence interval) of phantoms by FDM and PolyJet were 0.53 ± 0.46 and 0.98 ± 0.55 mm, respectively. Phantoms were used by surgeons for VATS training, which is considered more reflective of the clinical situation than the conventional simulation phantom. In conclusion, the patient-specific, realistic, and reusable VATS phantom provides a better understanding the complex anatomical structure of a patient and could be used as an educational phantom for esophageal structure replacement in VATS.

We report a case of an extremely low birth weight premature infant born at 27 weeks of gestation, transferred to our tertiary pediatric referral center for surgical repair of an esophageal atresia. Endoscopic evaluation before the start of surgery revealed a hypopharyngeal perforation, resulting in the false impression of esophageal atresia. If no tracheoesophageal fistula is found during tracheoscopy, esophagoscopy should be done before surgical intervention as the inability to pass a nasogastric tube into the stomach is not sufficiently reliable for a correct diagnosis of esophageal atresia., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 International Anesthesia Research Society.)

Background: Esophageal atresia with tracheoesophageal fistula (EA/TEF) is associated with many congenital and vascular malformations; however, reports utilizing computed tomography (CT) and computed tomography angiography (CTA) are limited. The objective of this study is to review CT scans of the chest from patients with EA/TEF and report their pulmonary and vascular findings., Methods: We completed a retrospective chart review of children with congenital EA/TEF evaluated in the aerodigestive clinic at Children's Hospital Colorado. Results of the most recent CTA or CT of the chest were investigated. Demographics, medical conditions, and bronchoscopy findings were also recorded. The ratio of tracheal lumen area between inspiratory and expiratory CTA images was measured., Results: Of the patients with congenital EA/TEF seen in the program, 47 patients had a chest CT available for review. Eight patients (17%) had bronchiectasis. Of the contrast CT scans, 15 (58%) had a vascular abnormality and 16 (62%) demonstrated tracheal compression (38% at the level of the innominate artery, 35% from other structures). Nineteen of the CTAs had volumetric expiratory images of the trachea to evaluate tracheomalacia. The mean expiratory:inspiratory area was 0.57 (SD ± 0.23) at the level of the innominate., Conclusion: Patients with EA/TEF frequently have vascular abnormalities that may alter airway mechanics as well as pulmonary comorbidities that may affect long-term management. For patients experiencing persistent respiratory symptoms, CTA of the chest should be considered adjunct to bronchoscopy to help with medical and surgical management of these children., (© 2020 Wiley Periodicals LLC.)

Tracheoesophageal fistulas (TEFs) are abnormal connections between the esophagus and tra-chea and are associated with atresia of the esophagus in most cases. Herein, we present a case of H-type TEF in a young woman which is successfully treated with slide tracheoplasty technique.

Objective: To analyze the outcomes of an open anterior cervical approach and tospecifically describe a novel extended tracheotomy incision ("Key-hole technique") torepair H-type and other challenging tracheoesophageal fistulae (TOF) at a singletertiary pediatric center., Method: A retrospective chart analysis of pediatric patients (0-18 years old) who had undergone repair of TOF's between January 2006 and March 2020 were reviewed. A case series of patients who had undergone open cervical utilizing three different techniques were included. Patient demographics, surgical management and post-operative surgical outcomes including complications were evaluated., Results: During the study period, 117 pediatric patients were diagnosed and anaged with TOFs with or without oesophageal atresia. Within this group, 12 patients (10%) had anterior open cervical repair of congenital or persisting TOFs (6 males and 6 females). Eight cases (7%) had congenital Type E (known as H-type), two had type D, one type B and one type C TOF. Median gestational age was 37 weeks (range 28-41 weeks), age of presentation ranged from 1 day old to 3 years old with 67% being diagnosed within the first month of life. At the time of definitive surgery all patients had a bronchoscopy and oesophagoscopy to confirm the diagnosis, identify the level of the fistula and place a catheter through the fistula. This cases series of open anterior cervical repair of TOFs comprised of seven (58%) patients who had primary extraluminal tracheal approach, four (33%) with extended tracheotomy incision ('Key-hole' technique) and one (9%) patient with slide tracheoplasty for recurrent type C TOF in the presence of subglottic stenosis. Eleven of the twelve patients had successful open anterior cervical repair of TOF. One patient who had primary open anterior cervical repair with the 'Key-hole' technique had recurrence managed successfully with slide tracheoplasty. There were no cases of recurrent laryngeal nerve injury., Conclusion: This series demonstrates that open anterior cervical approach to correct TOFs is an effective and safe method in the majority of cases of congenital and acquired fistulae where there is no oesophageal atresia or the atresia is corrected (in the case of recurrent or second fistulae). We also present the outcomes of a novel surgical "Keyhole" technique to manage TOF fistulas via an extended-tracheotomy incision. We also found that slide tracheoplasty is an effective salvage operation in the case of complex recurrent fistulae., (Crown Copyright © 2020. Published by Elsevier B.V. All rights reserved.)

Button batteries are the second most frequently-ingested foreign bodies and can lead to serious clinical complications within hours of ingestion. The purpose of this study was to analyze the outcomes of 14 children with button batteries lodged in the upper gastrointestinal tract.Totally 14 children with button batteries lodged in the upper gastrointestinal tract were included. The diagnosis was made primarily by the history of button battery ingestion, physical examination and chest-abdomen X-ray examination.The button batteries lodged in the esophagus were removed by esophagoscope, and those in the gastrointestinal tract were under observation. Among 10 children with batteries in the first esophageal stenosis, 9 were cured and 1 suffered from tracheoesophageal fistula. One case of battery in the second esophageal stenosis was dead due to intercurrent aortoesophageal fistula. Two cases of batteries in the third esophageal stenosis were cured after removal, and 1 case of the battery in the gastrointestinal tract discharged spontaneously.Ingested button batteries are mainly lodged in the esophageal stenoses and are easy to cause esophageal injury and severe complications. Early detection, prompt treatment, strengthening observation and regular follow-up after discharge may help to decrease the incidence of complications and improve the outcomes.

Rationale: Neonatal long-gap esophageal atresia (LGEA) with tracheoesophageal fistula (TEF) is an uncommon but serious congenital malformation of the esophagus in newborns, and it remains challenging for pediatric surgeons. Magnetic compress has been shown to be effective for the treatment of LGEA in children and adults. However, the implementation of this unique technique for neonatal LGEA has not been evaluated., Patient Concerns: A female infant was born at 37 weeks of gestation. Prenatal ultrasound imaging revealed signs of esophageal atresia, including the absence of the gastric bubble and polyhydramnios., Diagnoses: A diagnosis of LGEA with TEF was confirmed at birth by contrast X-ray., Interventions: She was treated with magnetic compression anastomosis (MCA) following an esophago-esophagostomy. Two magnetic rings were customized, and the MCA was conducted during the same stage surgery of ligating the TEF. Under the magnetic force, the 2 magnet rings pulled along the gastric tube to achieve anastomosis. The postoperative permanent suction of these 2 pouches was instituted, and spontaneous growth was awaited. Magnet removal was performed at 36 days, and enteral nutrition was continued via a gastric tube for 4 weeks at post-operation., Outcomes: The upper gastrointestinal contrast confirmed the anastomotic patency perfectly after 3 months. The patient was followed up for 18 months, and exhibited durable esophageal patency without dysphagia., Lessons: These results suggest that MCA is feasible and effective for treating LGEA in infants.

Repairing a large tracheoesophageal fistula with extensive involvement of the membranous wall of the trachea is sometimes troublesome because of the lack of an ideal replacement for the large defect. We report the successful use of a pedicled sternocleidomastoid musculocutaneous flap to repair a large tracheoesophageal fistula in which the cutaneous component was applied to the defect of the membranous trachea after tracheal resection and the muscular component was interposed between the tracheal and esophageal walls., (Copyright © 2020 The Society of Thoracic Surgeons.

Tracheoesophageal fistulas (TEF) in adults can be managed either surgically or endoscopically, depending on their etiology, size, anatomy and patient comorbidities. A 68-year-old female was admitted to the ER due to dysphagia and a cough. The patient had a medical history of TEF resulting from a tracheostomy and prolonged mechanical ventilation. Previous endoscopic treatment had failed, namely 3-attempts of closure with an over-the-scope clip (OTSC®). The patient refused surgery. After a multidisciplinary discussion (Gastroenterology, Pneumology, Surgery and Interventional-Cardiology), we decided to attempt Amplatzer-Occluder® placement. An 8mm Amplatzer-Occluder® was placed from the tracheal side, with sequential opening of the esophageal and tracheal strands (under endoscopic, bronchofibroscopic and fluoroscopic visualization). Nevertheless, migration of the device occurred 8-weeks later. Percutaneous endoscopic gastrostomy (PEG) was placed and the patient was referred to surgery. When there is extensive fibrosis that is not amendable to the application of clips, atrial septal defect occluder devices can be considered to manage TEF. Nevertheless, there is a need to develop strategies to minimize migration risk.
