Double H-type tracheoesophageal fistulas identified and repaired in 1 operation

Diagnose and treatment for Type D congenital esophageal atresia with tracheoesophageal fistula

Importance

Type D esophageal atresia (EA) with tracheoesophageal fistula (TEF) is characterized by EA with both proximal and distal TEFs. It is a rare congenital anomaly with a very low incidence.

Objective

To investigate diagnostic and treatment strategies for this rare condition.

Methods

We retrospectively reviewed the clinicopathological features of patients with EA/TEF treated at our institution between January 2007 and September 2021.

Results

Among 386 patients with EA/TEF, 14 (3.6%) had type D EA/TEF. Only two patients were diagnosed with proximal TEF preoperatively. Seven patients were diagnosed intraoperatively. Five patients were missed for diagnosis during the initial surgery but was later confirmed by bronchoscopy. During the neonatal period, seven patients underwent a one-stage repair of proximal and distal TEF via thoracoscopy or thoracotomy. Due to missed diagnosis and other reasons, the other 7 patients underwent two-stage surgery for repair of the proximal TEF, including cervical incision and thoracoscopy. Ten of the 14 patients experienced postoperative complications including anastomotic leakage, pneumothorax, esophageal stricture, and recurrence. Patients who underwent one-stage repair of distal and proximal TEF during the neonatal period showed a higher incidence of anastomotic leak (4/7). In contrast, only one of seven patients with two-stage repair of the proximal TEF developed an anastomotic leak.

Interpretation

Type D EA/TEF is a rare condition, and proximal TEFs are easily missed. Bronchoscopy may aim to diagnose and determine the correct surgical approach. A cervical approach may be more suitable for repairing the proximal TEF.

A dual H-type tracheoesophageal fistula; why not being repaired simultaneously? A case report and review of literature

BACKGROUND

H-type Tracheoesophageal Fistula (TEF) is a particular type of congenital esophageal anomalies, in which patients present with non-specific symptoms that can result in delayed diagnosis. Here, we report two pediatric cases with a rarer variant called ‟dual H-type TEFˮ.

CASE PRESENTATION

We present two cases of H-type TEF. The first was a 45-day-old boy with feeding problem and cyanosis while feeding, and the second was a three-month-old girl with cough and choking after feeding from the first day of birth. In both cases, two separate TEFs were detected during diagnostic evaluation by flexible bronchoscopy. Both were repaired simultaneously through a cervical incision. The first patient deteriorated 13 days after the surgery, disturbancing in acid-base balance and expired unfortunately.

CONCLUSION

Hence, it is necessary to consider the possibility of double TEF in any newly diagnosed H-type TEF.

Flexible Bronchoscopy Diagnosis of Uncommon Congenital H-type Tracheoesophageal Fistula, Dual Fistulae, Bronchoesophageal Fistula, and Recurrence of Fistula in Children: A 20-year Experience

BACKGROUND

Interventional pediatric flexible bronchoscopy has many advantages over radiologic investigations in diagnosing uncommon congenital H-type tracheoesophageal fistula (TEF), dual TEF, bronchoesophageal fistula (BEF) and fistula recurrence including higher rates of identification and anatomic localization with guide wire cannulation. We compare the diagnostic utility of flexible bronchoscopy to radiologic techniques for congenital aerodigestive fistula.

METHODS

A single center retrospective review was completed of all cases of pediatric TEF and BEF diagnosed with flexible bronchoscopy between January 2000 and November 2020.

RESULTS

Fistulae were diagnosed 21 times in 18 patients at a median age of 1.22 years (interquartile range: 0.50 to 2.99). The median time from diagnosis to repair was 17.5 days (interquartile range: 5.5 to 43). Symptoms commonly related to fistula were found in all patients. Uncommon fistulae included single H-type TEF (n=10, 47.6%), dual H-type TEF (n=2, 9.5%), dual proximal and distal TEF with esophageal atresia (n=5, 23.8%), TEF recurrence (n=2, 14.3%), BEF (n=1, 4.8%), and a BEF recurrence (n=1, 4.8%). Flexible bronchoscopy confirmed the diagnosis in all fistulae using a guide wire cannulation or methylene blue dye injection. A combined procedure with simultaneous bronchoscopy and esophagoscopy was used for 6 fistulae. The positive examination rate was 75% for bronchoscopy compared with 2.6% for contrast swallow studies and 28.6% for tube esophagograms.

CONCLUSIONS

Flexible bronchoscopy should be considered as a first line investigation in uncommon aerodigestive fistulae. In the absence of a skilled bronchoscopist, the best radiologic investigation is a pull-back tube esophagogram but may still require endoscopic confirmation at the time of fistula repair.

Detection of H-type bronchoesophageal fistula in a newborn: A case report and literature review

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.

H-type congenital tracheoesophageal fistula: Insights from 70 years of The Royal Children's Hospital experience

BACKGROUND

The long-term outcomes of H-type tracheoesophageal fistula (TOF), an uncommon variant of esophageal atresia/tracheoesophageal fistula (OA/TOF), are rarely described in the literature. We reviewed our institutional experience of 70 years.

METHODS

The Nate Myers Oesophageal Atresia Database was queried for patients with an H-type TOF (1948-2017). Data included presentation, diagnostic workup, surgical management, and outcomes.

RESULTS

Of 1088 patients with OA/TOF, 56 (5.1%) had an H-type TOF. The most common presenting symptoms were cyanotic episodes (68%), choking with feeds (52%), and aspiration pneumonitis (46%). The majority (82%) were symptomatic in the first week of life. Coexisting congenital anomalies were present in 46%: cardiac (13/56, 23%), genitourinary (10/56, 18%), and vertebral/skeletal (9/56, 16%). Patients were consistently diagnosed with prone contrast tube esophagogram (77% sensitivity on the first study and 96% after a second study). The fistula was most commonly approached through a right cervical collar incision. Right vocal cord palsy occurred in 22%, with one case of bilateral palsies. Other complications included leak (5.6%), recurrence (9.3%), stricture (1.9%), and diverticulum (1.9%). Although there was a trend towards a lower recurrence rate when interposition material was used, this was not statistically significant (3.3% vs 16.7%, p = 0.16). Survival in operative cases was 98.2%, and when all diagnosed cases were considered was 89.3%.

CONCLUSIONS

We have reported the largest single-center series of H-type TOF. Diagnosis is challenging, and surgical morbidity remains high. Despite this, long-term outcomes are favorable.

Practical safety in the diagnosis and treatment of congenital isolated tracheoesophageal fistula

The rareness of H-type tracheoesophageal fistula in conjunction with its unspecific clinical presentation and wide range of anatomical presentation makes its diagnosis and treatment a problematic topic for both ear, nose and throat (ENT) specialists and pediatric surgeons worldwide. Symptoms and clinical signs of H-TOF are easily misleading. Diagnostic methods, most of the times, are dependent on the physician's experience; therefore, various errors may be made. We analyzed our experience in managing H-TOF cases over the last 15 years. Advice and strategies of action for health professionals directly involved in the diagnosis and treatment were identified, but also errors and mistakes while managing 6 cases. We analyzed 'red flags' but also important steps in the practical safety concerning this rare congenital malformation. Choosing the surgical access for division of the fistula throughout the cervical or thoracic approach is sometimes difficult. A scrupulous perioperative planning is mandatory. A dynamic overview of the patient's presentation never underestimating the subtlety of H-TOF presentation should be conducted for its early recognition and achieving best outcomes.

Adolescent With VACTERL Association Presents With Recurrent Pneumonia

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 presented with a history of recurrent pneumonia, chest pain, and asthma and was found to have a previously undetected H-type TEF that was surgically repaired. When evaluating a patient with features of VACTERL, it is important to choose studies that can explore the presence of all associated features. Clinical history and type of imaging utilized can be essential in making a timely diagnosis, especially for H-type TEF.

Congenital H-type tracheoesophageal fistula: a national multicenter study

BACKGROUND

Congenital H-type tracheoesophageal fistula (TEF) is very rare and represents <5 % of all congenital tracheoesophageal malformations. This is a national, multicenter review of our experience with isolated H-type TEF outlining clinical presentation, methods of diagnosis, associated anomalies, treatment and outcome

PATIENTS AND METHODS

The medical records of all patients with the diagnosis of congenital H-type TEF treated at four pediatric surgery units in Saudi Arabia were retrospectively reviewed for: age at diagnosis, sex, presenting symptoms, associated anomalies, method of diagnosis, treatment and outcome.

RESULTS

During the study period (January 1998-December 2013), 435 infants and children with the diagnosis of esophageal atresia with or without TEF were treated. Among these, 23 (5.3 %) had isolated TEF. There were 11 males and 12 females. Their age at presentation ranged from 5 days to 3 years and 7 months but the majority (90 %) were diagnosed during their first year of life. Their clinical presentation included: chocking and coughing during feeds in 12 (52.2 %), recurrent chest infection in 16 (69.6 %) and cyanosis in 10 (43.5 %). One presented with abdominal distension also. The diagnosis was made using esophagogram. In 11 (47.8 %), a single study confirmed the diagnosis, 8 (34.8 %) required two studies while 4 (17.4 %) required three studies. Nineteen (82.6 %) had preoperative bronchoscopy and in 13 (56.5 %), a catheter was used to cannulate the fistula. All were operated through a right cervical incision except one who underwent thoracoscopic ligation and division of the fistula. In one, the fistula was only transfixed and tied without being divided. This patient developed a recurrent fistula. Two patients developed postoperative stridor secondary to recurrent laryngeal nerve palsy. In both of them, there was complete recovery.

CONCLUSIONS

H-type TEF is very rare and commonly presents with recurrent chest infection, chocking and coughing during feeds and cyanosis. Physicians caring for these patients should be aware of this and a high index of suspicion is of paramount importance to avoid delay in diagnosis with its associated morbidity. A contrast esophagogram is valuable in confirming the diagnosis. The study however may need to be repeated. Preoperative bronchoscopy is valuable to localize and cannulate the fistula for easier access during surgery. Surgical repair is the treatment of choice and this should be performed through a right cervical incision or thoracotomy for low fistulae. Thoracoscopic ligation and division of a low H-type fistula is an alternative and less invasive approach when compared to thoracotomy.

Cervical/thoracotomic/thoracoscopic approaches for H-type congenital tracheo-esophageal fistula: a systematic review

PURPOSE

Aim of this systematic review is to investigate the thoracic and cervical surgical approaches of H-type tracheo-esophageal fistula (TEF) according to the position of the fistula.

METHODS

The PubMed database was searched for original studies on H-type TEF treatment published between 1977 and 2012. Manuscripts finally included were divided into open and thoracoscopic surgery groups.

RESULTS

Seventeen studies were selected for open surgery group, and most of them agree on the importance of pre-operative diagnosis of the fistula by preliminary tracheoscopy. Right cervicotomy was used in 70 cases (76.9%), left cervicotomy in 12 (13.2%), and thoracotomy only in 9 (9.9%). Five studies were included in thoracoscopic group (6 patients). Indications for the surgical approach (cervical vs thoracic) according to the position of the TEF were clearly described in 10 manuscripts, and all stated differences in surgical technique details. Complications and mortality rates were not statistically correlated to the different surgical approaches.

CONCLUSIONS

The evidence base in regard to the treatment of H-type fistula in children is poor and the skills and preferences of the surgeons guide the choice of the procedure. Surgical division of the fistula is curative, and the key to a successful repair is the pre-operatively identification of the level of the fistula with tracheoscopy. Right cervicotomy seems to be the approach of choice in the majority of case, with the thoracic approach appropriate only for fistulae opening below T2. Further well-designed prospective studies which take into account of selection and performance bias are strongly required.
