Oversight in identification of H-type TEF, unsatisfactory radiological method, masquerading symptoms related to associated anomalies, and minute symptoms in some patients may cause delay in diagnosis. Radiological and endoscopic procedures are complementary in both diagnosis and treatment of H-type TEF VACTERL=vertebral, anal atresia, cardiac abnormalities, TEF and/or esophageal atresia, Renal agenesis and dysplasia and limb defects; Clinical findings. Presentation for all types is typically early, except for H-type which may go undiagnosed until late childhood; Symptoms include; Choking; Drooling; Difficulty handling secretions; Regurgitation; Aspiratio Congenital TEF can arise due to failed fusion of the tracheo-oesophageal ridges during the third week of embryological development. 1 Congenital isolated TEF (H-type) is a rare disorder posing diagnostic and management problems. 2 It was first described by Lamb in 1873. 3 This anomaly accounts for about 4% of tracheo-oesophageal malformations and has an incidence of around 1:50 000-80,000 births. 4 N-type TEF is more frequent than H-type due to the oblique angle of the fistula from the.
H-type TEF is characterized by a clinical triad consisting of paroxysms of coughing precipitated by feeding, gaseous distention of the gastrointestinal tract, and pneumonitis Many other diagnostic techniques have been advocated in cases of H-type TEF such as scintigraphy, direct sagittal computed tomography (CT) scan and virtual bronchoscopy. 3, 4, 5, 6 In spite of. The diagnosis of H type tracheoesophageal fistula (TEF) was made by rigid bronchoscopy. Successful surgical repair of H type TEF required right thoracotomy approach as fistula was quite low laying. Tracheo-bronchoscopy (especially rigid) is an important investigation due to the better visualization, in doubtful cases and to locate the exact location of fistula
When there is high suspicion for N (also known as H)-type TEF, a pull-back esophagram can be performed by placing a feeding tube into the stomach and gradually pulling back the tube and simultaneously injecting contrast material under direct visualization. 2 However, care should be taken to not inject contrast material too high within the esophagus or too vigorously, as tracheal aspiration can occur. This can be sometimes mistaken for an N-type TEF H-type tracheoesophageal fistula (H-TEF) is an uncommon congenital anomaly in which there is an abnormal communication between the trachea and the oesophagus1,2. It usually confidence in the radiological diagnosis of H-TEF. Ultimately, this will be guided by discussion with the clinical team and their index of suspicion Overall survival in patients with H-type TEF (see the image below) without esophageal atresia (ie, congenital isolated TEF) appears to be good, with a multicenter retrospective reporting a 97% overall survival and a 16% in-hospital complication rate (excluded vocal cord issues; the main complication was postoperative leak [8%]) in 102 patients
. Clinical Features EA is usually detected shortly after birth and should be suspected in an infant with drooling (excessive salivation) that is frequently accompanied by choking, coughing, and sneezing H-type Fistula without Esophageal Atresia (Gross Type E) H-type TEF without atresia is usually discussed together with EA because it may be part of the VACTERL association. It occurs with an incidence of about 4%. The fistula starts from the membranous trachea and runs caudad to enter the esophagus The radiological diagnosis of H-type TEF can be made by esophagography, tube cineesophagography or CT of the neck and upper thorax. Direct sagittal CT, three-dimensional CT and virtual bronchoscopy were all reported to be sensitive to detect H-type TEF [15, 16]. HRCT warned us about the H-type TEF and we decided to perform bronchoscopy at first. especially in H-type TEF cases is uncommon (10). H-type TEF is a rare anomaly and comprises only 4% of the congenital TEF. H-type TEF occurs between the level of the 5th cervical vertebra and 2 nd thoracic vertebra in up to 70% to 80% of patients and courses in an oblique route like the letter N instead of H, from the posterio infant with SS and associated H-type TEF diagnosed by using electrocardiography (ECG)-gated chest CT with detailed image descriptions. CASE REPORT A 3300 g male infant was born at 40 weeks of gestation via normal vaginal delivery as the first baby of a 32-year-old moth-er. No specific fetal anomalies were identified on the prenata
The second most common anomaly is pure atresia without tracheoesophageal fistula ( A-type,10%). The third most common variation is the H-type fistula, which consists of a tracheoesophageal fistula without esophageal atresia( E-type esophageal atresia. 4%). This aberration is more difficult to diagnose clinically picked up the H-type TEF on the CT scan (Figures 2-4). Bronchoscopy (Figure 5) and esophagoscopy confirmed the diagnosis. The TEF was big enough for the bronchoscope to pass from the trachea into the esophagus (Figure 6). Case Report Congenital H-type tracheoesophageal fistula in adults Hon Chi Sue Congenital isolated TEF (H‐type) is a rare disorder posing diagnostic and management problems.1 N‐type TEF is more frequent than H‐type, owing to the oblique angle of the fistula from the trachea (carina or main bronchi) to the oesophagus, anatomically at the level of the neck root (C7-T1). Pressure changes between both structures can cause entry of air into the oesophagus, or entry of. H-type fistula patients from China, only four (12.9%) were diagnosed before the age of 2 months and 12 (38.7%) were diagnosed after one year of age (19). The oldest patient reported to have congenital H-type TEF was 79 years old (20). Although associated anomalies are generally regarded to be less common in H-type TEF cases than in other form
INTRODUCTION. H-type or isolated tracheoesophageal fistula occurs along the spectrum of esophageal malformations. Five types of esophageal malformation are described in the literature. 1 The most common type is esophageal atresia with a distal tracheoesophageal fistula (75%). H-type tracheoesophageal fistulas occur without associated esophageal atresia and represent approximately 5% of all cases TEF is most commonly associated with other congenital anomalies, particularly cardiac defects (Vertebral, Anal, Cardiovascular, Renal and limb) anomalies.3 H type of tracheoesophageal fistula is rare and comprises only 4% of the cases of TEF.4 In the H type, the fistula runs from the posterior wall of trachea downwards to the anterior wall of.
H-type TEF is a very rare anomaly for the determination of which there are no universally recommended diagnostic procedures. Diagnostic testing includes modified barium swallow or fiber optic endoscopic evaluation of swallowing, both of which assess swallowing function. 5 , 6 No study has compared the sensitivity of these tests in the TEF. VATS Repair of H-type Tracheal-esophageal fistula without atresia. Presented at the American College of Surgeons - 66th Annual Puerto Rico Chapter Meeting, 2.. Tracheoesophageal fistula (TEF) without esophageal atresia, commonly called H-type or N-type or isolated fistula, is a rare variant of the spectrum of esophageal anomalies .It was initially classified as type 4 by Vogt in 1929  and later reclassified as type E by Gross in 1953 .In the neonatal period, an H-type TEF typically manifests with choking during feeding, recurrent cough.
We had five type D patients (2%) who had a proximal EA and a double fistula (both proximal and distal); an H-type TEF may occur in the absence of EA (type E) in 2% to 6% of cases. For the purpose of this chapter, we describe the operative management of the most common variants, beginning with type C and also discussing types A and E Type C EA/TEF: It is the most common type TEF, antenatal polyhydramnios is documented, presents in the newborn with vomiting and coiling of the NGT in the blind ended proximal esophagus, which is dilated secondary to the fetus' efforts to swallow amniotic fluid, which may compress the trachea resulting in tracheomalacia
Type E (H-type): A variant of type D, whereby the proximal and distal esophagus is in continuity and a TEF is present near the distal tracheal (4% of cases) • Acquired TEFs — Nonmalignant. Blunt or open trauma, iatrogenic injury, irritation from endotracheal or tracheostomy tube, or cuff causing pressure necrosis. Foreign-body ingestion. Radiology. Rheumatology. Transplantation. The third most common anomaly is the H-type fistula, which consists of a TEF without esophageal atresia. H-type of tracheoesophageal fistula H-type TEF is an important treatable cause of recurrent/ persistent respiratory symptoms in infants and children. The association of H-type TEF and incomplete double aortic arch, a rare vascular anomaly, is not hitherto reported in literature. The preoperative diagnosis of these co-existing defects is importan
= Abstract = H-type tracheoesophageal fistula (TEF) is extremely rare in infants and children, and clinical manifestations of this condition are diverse based on its severity. Some cases of congenital TEF diagnosed in adulthood have been reported, which indicate the difficulty of early diagnosis of this disease. Gastroesophageal reflux (GER) may induce chronic aspiration, pulmonary aspiration. The condition H type TEF, may present mild symptoms of repeated aspiration and pneumonia to life-threatening events. The symptoms may occur in the neonatal period to the oldest reported patient was 79 years old (4). The main symptoms of an H-TEF include recurrent pneumonitis, cyanosis, and choking on feeding and abdominal distension Congenital tracheoesophageal fistula (TEF) without esophageal atresia is commonly known as H type. This is extremely rare in infants. The rarity of the condition, its nonspecific symptomatology, and limitations in its demonstration by contrast radiology and endoscopy contribute to delays between first presentation and confirmation of the. BACKGROUND H-type tracheoesophageal fistula (TEF) was diagnosed in 12 patients during the 25 years from 1971 to 1996. Although all patients were symptomatic since birth, in 58% of the cases, there was a diagnostic delay ranging from 26 days to 4 years Diagnosis of pediatric dual TEF and H-TEF has no standardized endoscopic approach. 1, 2, 4, 5 The cases presented were challenging with diagnostic delays and falsely negative radiological investigations (Table 1) before being identified with flexible bronchoscopy (Video S1)
. We describe here the steps of the surgical repair of an H-type tracheoesophageal fistula. Advanced. Procedure. A direct laryngoscopy and bronchoscopy was initially performed. The fistula was identified again at the mid. In all types excluding type E, chest X-ray shows the NG tube looped in the proximal oesophageal pocket. Air in the stomach is indicative of a distal TEF (types C/D), while a gasless stomach excludes a distal TEF (types A/B). A proximal TEF may be revealed fluoroscopically with the use of a small amount of nonionic contrast material  Zhu H, Shen C, Xiao X, Dong K, Zheng S.

[Medline] 10.1055/b-0038-162792 8.5 Tracheoesophageal Fistula and Esophageal Atresia Key Features Tracheoesophageal fistula (TEF) and esophageal atresia (EA) are the result of a congenital communication between the trachea and esophagus. EA is also present in most cases of TEF. These congenital anomalies present with respiratory and/or feeding difficulties in the newborn
This is the rarest form of EA/TEF affecting less than 1 percent of cases. TYPE E In this form, the esophagus is intact and connects normally to the stomach. However, a TEF is present connecting the esophagus and the trachea. This is also known as H-type fistula. (4 percent) H-Type Tracheoesophageal Fistula and Congenital Esophageal Stenosls* Douglas N. Homnick, M.P.H., M.D., F.C.C.P.t An 18-month-old boy was seen in the pediatric pulmonary clinic with a history of wheezing, stridor and intolerance to solid foods. Barium esophagram revealed distal esophageal stenosis and subsequently an H-type TEF at surgery Type 1. This is the most common type (50%) composed of variable cysts with at (one dominant cyst (greater than 2 cm in diameter). Prognosis is excellent and there is infrequent association with other congenital abnormalities (5% ). Imaging Type 1 lesions have one or more dominant cysts with adjacent smaller cysts Rarely, a small congenital H-type TEF (communicates with a normal esophagus) may present in adulthood.

Three conditions where this may occur include H-type tracheoesophageal fistula (TEF), proximal TEF with distal esophageal atresia, and esophageal bronchus in which an anomalous bronchus originates from the esophagus. Patients with these rare conditions typically present with acute respiratory distress after the first feeding Abbreviations: CLO = congenital lobar overinflation, CPAM = congenital pulmonary airway malformation, H-E = hematoxylin-eosin RadioGraphics 2010; 30:1721-1738 • Published online 10.1148/rg.306105508 • Content Codes
Classification• In 1929 E. C. Vogt, a radiologist classified the anomaly anatomically:• Type 1: absent esophagus.• Type 2: EA without TEF.• Type 3: EA with fistula: • a: EA with proximal TEF • b: EA with distal TEF • c: EA with proximal & distal TEF.• Type 4: isolated TEF with intact esophagus. 7 Esophageal atresia, with or without tracheoesophageal fistula, is a fairly common congenital disorder that family physicians should consider in the differential diagnosis of a neonate who develops. VACTERL is a condition that includes various anatomic anomalies including vertebral, cardiac, tracheoesophageal fistula (TEF), renal, and limb defects. TEF can be found in up to 80% of patients with the condition. Although TEFs are usually identified early in life, the H-type TEF can be more difficult to detect. We report the case of a 15-year-old male with a previous diagnosis of VACTERL who. Radiology. 2003;228(2):379-388. 20. Langer JC, Hussain H, Khan A et al.

3) Esophageal ateresia(EA) can occur in presence or absence of TEF, rarely, TEF can occur without EA (H-type fistula). 4) 1:3,000 live births, sporadically. 5) 50-75% of those have associated anomalie Type E - TEF without esophageal atresia or so-called H-type fistula (4%) Type F - Congenital esophageal stenosis (<1%) (not discussed in this article) A fetus with esophageal atresia cannot effectively swallow amniotic fluid , especially when TEF is absent; in a fetus with esophageal atresia and a distal TEF, some amniotic fluid presumably.
Type C, which consists of a proximal esophageal pouch and a distal TEF, accounts for 84 percent of cases. TEF occurs without EA (H-type fistula) in only 4 percent. Other rare variations have been reported. TEF and EA are caused by a defect in the lateral septation of the foregut into the esophagus and trachea Type 1. This is the most common type (50%) composed of variable cysts with at (one dominant cyst (greater than 2 cm in diameter). Prognosis is excellent and there is infrequent association with other congenital abnormalities (5% ). Imaging Type 1 lesions have one or more dominant cysts with adjacent smaller cysts

This includes x-rays, CT (computed tomography or CAT), Ultrasound, MRI and chest procedures, such as lung biopsy and thoracentesis or drainage of fluid from the chest. Emergency Radiology The least common form of TEF is the H-type fistula, which connects the esophagus and trachea (creating the appearance of a capital H) but does not involve EA. An H-type fistula affects between 1% and 4% of patients with EA/TEF. 6,7. During embryonic development, the trachea and esophagus share a common lumen Tracheoesophageal fistula (TEF) in dogs is a rare disease with only few reports in the literature. This report aims to contribute to the current literature on suitable diagnostic methods for TEF and to provide follow-up information after successful surgical treatment. A seven-month-old intact female Spanish Water Dog was presented for further investigation of recurrent respiratory symptom Surgery for EA and TEF is performed through an opening on the side of your baby's chest. Depending on the type of surgery your child needs, this will either be one long opening or several small openings. The first step in esophageal atresia repair — whether your baby has EA/TEF or EA alone — is a bronchoscopy. In a bronchoscopy, a small.

Purpose: This study was performed to evaluate the management of tracheoesophageal fistula (TEF) ± esophageal atresia (EA) under the guidance of preoperative tracheo-bronchoscopy (TrSc). Methods: Between 2007 and July 2014, a total of 26 consecutive newborns who underwent rigid TrSc for suspected TEF were identified. All associated charts and operation reports were retrospectively analyzed TEF is identified by an abnormal connection (fistula) between the esophagus and trachea and is the most common type of airway fistula. Typical symptoms in case of TEF are choking following food intake, severe coughing, feeding disorders, and unmanageable pneumonia (1,3). The quality of life of patients with TEF is poor
H-type TEF, which has fewer symptoms and is typically diagnosed when the child is at least four months old, is also easier to repair when the child's size and weight have increased. The esophagus can be dilated periodically during the growth period and a stomach tube used to decompress the stomach until the surgical repair is performed Tracheoesophageal fistula demarcates an open connection between the esophagus and the trachea. It is frequently associated with esophageal atresia, while malignant diseases of the esophagus and instrumentation are other notable factors. Aspiration of gastric contents, coughing after swallowing and frequent pneumonia are reported symptoms. The diagnosis is made by either bronchoscopy or barium.

Pulmonary radiography suggested a type III esophageal atresia. Surgery was performed on day 1 to cure the atresia and close the tracheoesophageal fistula, with success. Surgical exploration and complementary exams showed: a type III esophageal atresia, a dextrocardia, and a severe right pulmonary atresia associated with right pulmonary artery. KFSH&RC at 15 ± 29 months. Period of follow up was 5 ± 3.8 years. Diagnosis of TEF was based on nasogastric tube coiling (NGT) and by dilated blind esophagus in chest x-ray in 40 (98%) of the patients. EA and distal TEF were found in 37 (90%) of the patients, isolated EA in 2 (5%) and H-type fistula in 2 (5%) of the patients.

Alic, Moataz El Tayeb El Shaarawayd aDepartment of Diagnostic Radiology, Faculty of Medicine, Assiut University, Egypt bDepartment of Diagnostic Radiology, Taibah University, Saudi Arabi Oesophageal atresia (OA) is a rare condition where a short section at the top of the oesophagus (gullet or foodpipe) has not formed properly so is not connected to the stomach. This means food cannot pass from the throat to the stomach. Tracheo-oesophageal fistula (TOF) is another rare condition, which tends to occur alongside oesophageal atresia EA without TEF does not permit any passage of gas into the bowel, but a TEF permits a pathway from the trachea to the distal esophagus and the stomach. In rare instances, infants have a tracheoesophageal fistula without an esophageal atresia. This is known as an H-type TEF (the connection between the esophagus and trachea looks like an H)

Whilst the diagnosis of esophageal atresia is readily made shortly after birth, patients with an isolated H type TEF can present with varying degrees of symptomatology which can pose a diagnostic challenge  Background: Esophageal diverticulum (ED) is an extremely rare complication of congenital esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) surgery. We aimed to investigate feasible methods for the treatment of this rare complication.Methods: We retrospectively reviewed all patients with EA/TEF at Beijing Children's Hospital from January 2015 to September 2019 Background: The management of infants (infs.) with esophageal atresia and tracheoesophageal fistula (EA ± TEF) is demanding and complex. The aim of this study was to evaluate early morbidity, the timing of surgery, and the results of surgery. Patients and Method: We collected data of 30 consecutive infs. treated for EA ± TEF between 2006 and 2014
