Endoscopic esophageal and tracheal cauterization for closure of recurrent tracheoesophageal fistula: A case report and review of the literature

Airway and anesthesia management in tracheoesophageal fistula closure implantation: a single-centre retrospective study

OBJECTIVE

To review and analyze the airway and anesthesia management methods for patients who underwent endoscopic closure of tracheoesophageal fistula (TEF) and to summarize the experience of intraoperative airway management.

METHOD

We searched the anesthesia information system of the First Affiliated Hospital of Nanjing Medical University for anesthesia cases of TEF from July 2020 to July 2023 and obtained a total of 34 anesthesia records for endoscopic TEF occlusion. The intraoperative airway management methods and vital signs were recorded, and the patients' disease course and follow-up records were analyzed and summarized.

RESULTS

The airway management strategies used for TEF occlusion patients included nasal catheter oxygen (NCO, n = 5), high-flow nasal cannula oxygen therapy (HFNC, n = 4) and tracheal intubation (TI, n = 25). The patients who underwent tracheal intubation with an inner diameter of 5.5 mm had stable hemodynamics and oxygenation status during surgery, while intravenous anesthesia without intubation could not effectively inhibit the stress response caused by occluder implantation, which could easily cause hemodynamic fluctuations, hypoxemia, and carbon dioxide accumulation. Compared with those in the TI group, the NCO group and the HFNC group had significantly longer surgical times, and the satisfaction score of the endoscopists was significantly lower. In addition, two patients in the NCO group experienced postoperative hypoxemia.

CONCLUSION

During the anesthesia process for TEF occlusions, a tracheal catheter with an inner diameter of 5.5 mm can provide a safe and effective airway management method.

Recent Advances in the Genetic Pathogenesis, Diagnosis, and Management of Esophageal Atresia and Tracheoesophageal Fistula: A Review

Infants born with esophageal atresia and tracheoesophageal fistula, a complex congenital malformation occurring in 1/2500-4000 live births, may suffer threats to their cardiac, respiratory, and digestive health in addition to anomalies that may exist in the genitourinary and musculoskeletal systems. Optimal care for these patients throughout their lives is best achieved through a coordinated, multidisciplinary approach that our health care system is not always well-equipped to provide. This review, though not exhaustive, highlights the components of care that pertain to initial surgical reconstruction and subsequent diagnosis and management of the complications that are most frequently encountered. Authors from among the many specialties involved in the care of these patients summarize the current best practice with attention to the most recent advances. Assessment and improvement of quality of life and transition to adult specialists as children grow to adulthood is also reviewed.

Endoscopic interventional therapies for tracheoesophageal fistulas in children: A systematic review

Methods

An electronic literature search was performed using the keywords "tracheoesophageal fistula," "endoscopic," and "children" in the four major medical databases (Ovid, Embase, PubMed, and Web of Science) right from inception to September 2022. All English language articles describing the endoscopic interventional therapies of TEF in children were reviewed. Two independent researchers screened eligible articles at the title and abstract level. Full texts of potentially relevant articles were then screened again, and reference lists were screened manually to identify additional studies. Relevant data were extracted and analyzed. A synthesis of the relevant data was presented in descriptive form because of the heterogeneity of the included articles. The Chi-Squared test was used with a significance level of 5% (P < 0.05).

Results

Among the 1,167 retrieved papers, a total of 46 studies describing 170 TEF patients with an age range of 0.3-175 months were included, including 11 cases of acquired tracheoesophageal fistula, 144 cases of recurrent tracheoesophageal fistula, and 15 cases of congenital tracheoesophageal fistula (H-type TEF). A total of 119 out of 170 fistulas were successfully blocked via endoscopic techniques with an overall success rate of 70.0%, while 48 fistulas failed to close by endoscopic interventions, following which the procedure was converted to open surgery. No obviously severe intraoperative/postoperative complications occurred during the follow-up period, but only a mild esophageal stricture was noticed in six patients and grade II tracheal stenosis in one patient. Two patients died from causes unrelated to endoscopic procedures, with a mortality rate of approximately 1.2%. A comparative assessment of different endoscopic interventional techniques for TEF that detected endotracheal stenting was performed in six patients and one fistula was successfully blocked (16.7%). De-epithelialization alone was performed in 65 patients and the fistula healed in 47 of them (72.3%), with the mean number of successful treatments required being 2.3 times. Chemical sealant injection was administered in 33 patients and success was achieved in 21 (63.6%). The average requirement for endoscopic procedures was 1.5 times. De-epithelialization, in combination with chemical sealant injection, was performed in 62 patients, achieving the highest success rate of 77.4% (48 patients). Other treatment methods were performed in four patients and successfully treatment outcomes were reported in two of them (50.0%). The mean number of successful treatments required was four times, and a treatment was converted to surgery in one patient (25.0%). An assessment of different TEF types showed that 9 out of 15 congenital TEFs, 7 out of 11 acquired TEFs, and 103 out of 144 recurrent TEFs were successfully occluded. A comparison of the success rate across multiple groups showed a significant difference with a score of P < 0.05, while there was no significant difference in the success rate of different TEF-type groups (P > 0.05).

Conclusion

Endoscopic intervention is currently a preferred treatment modality for children with TEF because of its less-invasive nature, less complications, and high success rate. Among all interventional techniques, de-epithelialization, in combination with chemical sealant, has a higher success rate than other techniques. However, due to the limited number of cases reported for implementing many kinds of techniques, an ideal endoscopic interventional technique has yet to be devised, often necessitating more treatment applications and close follow-up.

The largest report on thoracoscopic surgery for recurrent tracheoesophageal fistula after esophageal atresia repair

BACKGROUND

Although thoracoscopic surgery has become the routine surgical method for esophageal atresia/tracheoesophageal fistula (EA/TEF), thoracoscopic treatment for recurrent tracheoesophageal fistula (rTEF) is far from popularized.

OBJECTIVES

We aimed to explore the safety and efficacy of thoracoscopic treatment for rTEF with a large-cohort study.

METHODS

We retrospectively analyzed the clinical characteristics and outcomes of 103 consecutive patients who underwent thoracoscopic surgery for rTEF by one surgeon after EA/TEF repair at two different institutions in China from 2014 to 2021.

RESULTS

One hundred and three pediatric patients (67 boys) were enrolled and the primary operations were performed via thoracoscopic (n = 75, 72.82%) or open surgery (n = 28, 27.18%). The median age at rTEF diagnosis was 5 (3, 10) months after the primary repair. Patients were diagnosed with recurrent fistula to the trachea (n = 97, 94.17%), bronchi (n = 4, 3.88%), and lung parenchyma (n = 2, 1.94%), and all of them underwent thoracoscopic surgery at a median age of 7 (5, 14) months with a median weight of 6200 (4870, 7650) g. After the repair of rTEF, the incidence of esophageal leakage, esophageal stricture, and TEF recurrence were 12.8%, 33.4%, and 10.8%, respectively. After the follow-up, 87 patients survived, 6 died, and 10 were lost to follow-up.

CONCLUSIONS

The results of thoracoscopic surgery for rTEF were comparable with previously reported thoracotomy surgery. Owing to the clear field during the operation, rapid patient recovery and esthetic results, the thoracoscopic approach could be a better choice for experienced pediatric surgeons.

Outcomes of Endoscopic Closure of Respiratory Esophageal Fistula in Children Using the Esophageal Approach: A Case Series

Repository-esophageal fistula (REF) in children includes congenital or acquired tracheoesophageal fistula (TEF) and pleuro-esophageal fistula (PEF). TEF is a well-known congenital anomaly that is managed surgically. Recurrent tracheoesophageal fistula (rTEF) occurring after surgical repair of TEF is not an uncommon complication and most of the time requires repeat surgery. The aim of this paper is to report the outcomes of endoscopic closure of REF in children in Oman. This is a retrospective case series describing the endoscopic closure of REF in children in the Royal Hospital (RH), Oman. Five cases were identified with one of them having acquired PEF while the rest had rTEF. All children had esophageal endoscopic closure of the esophageal fistula using endoclips, cauterization, and glue injection. The patient who had PEF had successful closure of the fistula and only one out of four with rTEF had successful endoscopic closure. Esophageal endoscopic approach is unsatisfactory in the closure of rTEF but could be effective in the closure of inflammatory PEF. An esophageal approach for the closure of rTEF may need to be consolidated with simultaneous bronchoscopic closure.

The multidisciplinary management of recurrent tracheoesophageal fistula after esophageal atresia: Experience with 135 cases from a tertiary center

BACKGROUND & AIMS

Recurrent tracheoesophageal fistula (rTEF) after esophageal atresia requires complex management across different specialties. This study reviews our experience and discusses a multidisciplinary (MDT) approach adopted in the past 4 years.

METHODS

We reviewed the medical records of 100 patients with rTEF managed by an MDT approach (post-MDT group) from 2016 to 2019. These cases were compared to a historical group of 35 patients with rTEF from 2012 to 2015 (pre-MDT group).

RESULTS

Of the 135 patients with rTEF, 124 were referred from other hospitals. Preoperative examination found tracheomalacia in 23 patients, vocal fold immobility in 19 patients, and laryngomalacia in five patients. The incidence of postoperative anastomotic leak, anastomotic stricture, and repeat recurrences was 28.1%, 23.0%, and 8.9%, respectively. The overall mortality rate was 4.4%. No statistical difference in postoperative complications was noted between the two groups. The duration of stay in the pediatric intensive care unit (P = 0.038), the duration of intubation (P = 0.049), the postoperative hospital stay (P = 0.011), and the total length of hospital stay (P = 0.001) were significantly lower in the post-MDT group. Mid-term follow-up showed 23 patients had pathological gastroesophageal reflux. Five of them underwent fundoplication and recovered.

CONCLUSION

The MDT approach by fostering coordination of surgical, medical, radiological, and nutritional management is beneficial in the management of rTEF and leads to a satisfactory outcome .

Thulium LASER for endoscopic closure of tracheoesophageal fistula in esophageal atresia's spectrum: An appropriate tool?

PURPOSE

To report our experience with endoscopic Thulium LASER for treatment of recurrent TEF after EA surgery, and for H-Type fistulas.

METHODS

A retrospective chart review of consecutive patients undergoing standardized endoscopic closure as first line therapy of recurrent tracheoesophageal fistula (RTEF) and H-type fistula using Thulium LASER, from 2013 to 2019, in a pediatric tertiary care center. Control endoscopic procedure was systematically performed. If persistence of the TEF was noted an external approach was performed. Patient demographics, medical history, symptoms, TEF type, treatment modalities, complications and outcomes were collected.

RESULTS

Eleven patients with tracheoesophageal fistula were included: six RTEF after primary repair of esophageal atresia and five H-type fistulas. The average age at endoscopic treatment was 19 months (SD 23 months, range 13 days-63 months). Closure of the fistula after single endoscopic procedure with Thulium LASER was obtained in 3 RTEF (50%) and 1 H-type fistula (20%). Six patients with failure of endoscopic treatment were cured after a single external procedure without any complications. One child, treated for H-type fistula, presented a severe complication of Thulium LASER treatment. Median follow-up after last repair was 24 months (range: 14-72 months). All fistulas were successfully treated.

CONCLUSIONS

In H-Type fistula, success rate of Thulium LASER is only 20% and thus should not be used. In contrast, in RTEF, success rate of 50% is achieved, avoiding as many open procedures, and Thulium LASER could be considered as first line treatment. In any case, open surgery is safe and efficient and can be considered as a first-line treatment for H-type fistulas, and as a salvage treatment for endoscopic treatment failures.

Surgical Treatment of Type III Laryngotracheoesophageal Clefts: Techniques and Outcomes

OBJECTIVES/HYPOTHESIS

Determine surgical and swallowing outcomes after surgery for type III laryngotracheoesophageal cleft (LTEC).

STUDY DESIGN

Case series with chart review.

METHODS

Chart review was performed on patients with type III LTEC between 2000 and 2019. Demographics, surgical outcomes, and swallowing outcomes were collected and analyzed.

RESULTS

Thirty-three patients met inclusion criteria (28 open and 5 endoscopic repairs). Mean age was 3.4 years for the open group and 0.9 years for the endoscopic group. Seventeen (51.5%) patients had a syndromic diagnosis, most commonly Opitz syndrome and Trisomy 21. Mean follow-up was 33.6 months. Thirteen (39.4%) patients had a previous repair attempt prior to repair at our institution. Twenty-four (70.6%) patients had a tracheostomy prior to or at the time of surgical repair and 13 (38.2%) remain tracheostomy-dependent. Nine patients (27.3%) required a revision cleft repair and four (12.1%) required two revisions. Thirty-one patients had an intact repair at last follow-up (93.9). Two patients died outside the hospital over a year after surgery. Preoperatively 13 of 17 patients with swallowing evaluations aspirated. After repair, 11 of 20 patients were deemed safe for all consistencies and seven were safe for thickened. Endoscopic approaches were performed during the last 2 years of the study and had significantly lower operative time (354.4 minutes vs. 171.5 minutes).

CONCLUSIONS

Endoscopic and open approaches are effective for treatment of type III LTEC with 27.3% requiring revision and 93.9% of repairs intact at last follow-up. Overall swallowing outcomes were good in patients who underwent postoperative instrumental swallow evaluation.

Care recommendations for the respiratory complications of esophageal atresia-tracheoesophageal fistula

Tracheoesophageal fistula (TEF) with esophageal atresia (EA) is a common congenital anomaly that is associated with significant respiratory morbidity throughout life. The objective of this document is to provide a framework for the diagnosis and management of the respiratory complications that are associated with the condition. As there are no randomized controlled studies on the subject, a group of experts used a modification of the Rand Appropriateness Method to describe the various aspects of the condition in terms of their relative importance, and to rate the available diagnostic methods and therapeutic interventions on the basis of their appropriateness and necessity. Specific recommendations were formulated and reported as Level A, B, and C based on whether they were based on "strong", "moderate" or "weak" agreement. The tracheomalacia that exists in the site of the fistula was considered the main abnormality that predisposes to all other respiratory complications due to airway collapse and impaired clearance of secretions. Aspiration due to impaired airway protection reflexes is the main underlying contributing mechanism. Flexible bronchoscopy is the main diagnostic modality, aided by imaging modalities, especially CT scans of the chest. Noninvasive positive airway pressure support, surgical techniques such as tracheopexy and rarely tracheostomy are required for the management of severe tracheomalacia. Regular long-term follow-up by a multidisciplinary team was considered imperative. Specific templates outlining the elements of the clinical respiratory evaluation according to the patients' age were also developed.

Recent advancements in the minimally invasive management of esophageal perforation, leaks, and fistulae

INTRODUCTION

Historically, the gold standard management of esophageal perforations, leaks, and fistulae has been traditional open surgery, but it is associated with significant morbidity and mortality. Minimally invasive approaches offer alternatives to surgery in treating hemodynamically stable patients with such defects. In this review article, we will discuss the recent advancements in the minimally invasive management of esophageal perforations, leaks, and fistulas.

AREAS COVERED

This review includes information from case reports, case series, and clinical trials on minimally invasive management of esophageal perforations, leaks, and fistulas. The focus is on the devices, outcomes, and application of the technology.

EXPERT COMMENTARY

Minimally invasive treatment represents significant progress in the management of esophageal perforations, leaks, and fistulas. Based on current evidence, it seems safe and effective but it is evolving and more studies are needed to help draw definitive conclusions.

Endoscopic management of tracheoesophageal fistulas

Tracheoesophageal fistulas (TEF) are pathologic communications between the trachea and esophagus. TEF can lead to significant respiratory distress that may result in lethal respiratory compromise, often due to recurrent and intractable infections. Through the use of endoscopy, some TEF can be successfully repaired using different approaches depending on the size, location, availability, and experience of the treating endoscopist. The aim of this manuscript is to provide an up-to-date review of the endoscopic management of TEF for gastroenterologists.
