Tracheoesophageal fistula due to Candida and Actinomyces co-infection: A case report and comprehensive review of the literature.

Acquired benign tracheoesophageal fistulas and bronchoesophageal fistulas (TEF) are typically associated with granulomatous mediastinal infections, 75% of which are iatrogenic. Candida albicans and Actinomyces are commonly occurring organisms, but are uncommon etiologies of TEF. Normal colonization and the slow growth characteristics of some species of these agents rarely result in infection, mycetoma, and broncholithiasis, and thus, delays in diagnosis and treatment are likely. Few reports describe C. albicans or Actinomyces spp. as the etiology of TEF or broncholithiasis. Herein, we report a case of benign acquired TEF secondary to coinfection of Candida and Actinomyces complicated by the formation of an actinomycetoma and broncholithiasis and a comprehensive literature review to highlight the unique nature of this presentation and offer a diagnostic algorithm for diagnosis and treatment of TEFs. Following a presentation of three months of productive cough, choking sensation, night sweats, and weight loss, a bronchoscopy revealed a fistulous connection between the esophagus and the posterior right middle lobe. Pathology identified a calcified fungus ball and a broncholith secondary to the co-infection of Candida and Actinomyces. This unique presentation of Candida and Actinomyces co-infection and the associated diagnostic algorithm are presented as education and a useful tool for clinicians.

Unmasking the Invisible: A Case Study of Aspiration Pneumonia Unveiling a Bronchoesophageal Fistula.

Bronchoesophageal fistula (BEF) is a rare, yet clinically significant, condition characterized by an abnormal connection between the bronchial tree and the esophagus. We present the case of a 25-year-old female who initially presented with symptoms of aspiration pneumonitis and was subsequently diagnosed with BEF, attributed to poorly differentiated squamous cell carcinoma. Despite initial attempts at palliative intervention through esophageal stent placement, persistent symptoms prompted further investigation, revealing the underlying malignancy. This case underscores the diagnostic challenges associated with BEF, particularly when malignancy is involved, and emphasizes the importance of a multidisciplinary approach in optimizing patient outcomes. Early recognition, thorough evaluation, and comprehensive oncological management are essential in addressing the clinical complexities posed by BEF. Further research is warranted to better understand the pathophysiology and optimal management strategies for this rare but clinically significant condition.

A Rare Case of Esophageal Carcinoma Cuniculatum Palliated by Esophageal and Endobronchial Stenting.

Carcinoma cuniculatum is a rare variant of well-differentiated squamous cell carcinoma. To date, there are less than 30 cases of esophageal carcinoma cuniculatum reported. It is frequently a diagnostic challenge: A definitive diagnosis typically cannot be made before esophagectomy. We present a uniquely aggressive case of esophageal carcinoma cuniculatum complicated by a bronchoesophageal fistula and successfully palliated with dual esophageal and endobronchial stenting.

Management of aero-digestive fistulas in adults: the bronchoscopist's perspective.

Aero-digestive fistulas (ADFs) are pathologic connections between the airways and gastrointestinal system. These most commonly occur between the central airways and esophagus. Fistulas may develop congenitally or be acquired from a benign or malignant process. Most fistulas presenting in adulthood are acquired, with similar rates of benign and malignant etiologies. Symptoms may severely impact a patient's quality of life and result in dyspnea, cough, and oral intolerance. ADFs have been associated with increased mortality, often related to pneumonias and malnutrition. Management is multifaceted and includes a multidisciplinary approach between the pulmonologist, gastroenterologist, and thoracic surgeon. While definitive management can be achieved with surgery, this is typically reserved for benign causes as surgical repair is often impractical in patients with advanced malignancies. With malignant causes, less invasive endoscopic and/or bronchoscopic interventions may be indicated. Stenting is the most common non-surgical invasive intervention performed. Stents can be placed in the esophagus, airway, or both. There is limited data that suggests outcomes may be better when esophageal stenting is performed with or without airway stenting. Airway stents are indicated when there is airway compromise, inadequate sealing of the fistula with an esophageal stent alone, or when an esophageal stent cannot be placed. This review will provide an overview of approaching ADFs from the bronchoscopist's perspective.

Characteristics and Outcomes of Surgical Treatment for Bronchial Anomalies.

OBJECTIVES: Bronchial anomalies are rare but challenging conditions to treat in children, encompassing a variety of structural abnormalities that could compromise airway patency. This includes complete rings, absent cartilage, traumatic avulsions, bronchoesophageal fistulas, and cartilaginous sleeves. The objective of this study is to describe the characteristics and outcomes of a series of pediatric cases of bronchial anomalies that were treated by slide tracheobronchoplasty. METHODS: This is a single-institution retrospective case series of pediatric patients with bronchial anomalies who underwent surgical treatment between February 2004 and April 2020. Data extracted from electronic medical records included patient demographics, comorbidities, and surgical outcomes. RESULTS: There were a total of 29 patients included in the study, of which 14 had complete bronchial rings, 8 had absent bronchial rings, 4 had traumatic bronchial avulsions, 2 had bronchoesophageal fistulas, and one had a cartilaginous sleeve. Median follow-up time was 13 months (with a range of 0.5-213 months). The overall mortality rate was 17.2% (5 patients), all of whom had complete bronchial rings. Patients with complete bronchial rings also had a higher rate of not only cardiac (85.7%) and pulmonary comorbidities (85.7%) but also secondary airway lesions (78.6%). CONCLUSION: This is the largest series to date describing surgical treatment for bronchial anomalies. Complete bronchial rings were the most common anomaly treated, followed by absent rings and trauma. Surgical treatment can be successful but mortality rates are higher in patients with complete bronchial rings, possibly due to higher rates of pulmonary and cardiac comorbidities.

New improved incision-tubing approach for bronchoesophageal Fistula with mediastinal abscess after esophagectomy: A case report.

Bronchoesophageal fistula is a serious threat to the survival after esophagectomy for esophageal cancer. The erosion of mediastinal abscess post anastomotic leakage is the most likely directly cause. However, the bronchoesophageal fistula with gastric conduit necrosis and mediastinal abscess is refractory to either surgical or conservative treatment. In the article, a unique case of Bronchoesophageal fistula with mediastinal abscess after gastric conduit necrosis is presented. A 74-year-old female was detected the right inferior bronchus-esophageal fistula with mediastinal abscess on 15 postoperative day after esophagectomy for esophageal cancer. A successful new improved minimally invasive management was performed.

Successful Management of a Child with Bronchoesophageal Fistula Associated with Other Anomalies.

Bronchoesophageal fistulas (BEFs) are rare malformations characterized by abnormal communication between the bronchus and the esophagus. Herein, we report a successful management of a child with BEF discovered as an intraoperative surprise and associated with the short gut, annular pancreas, and disorder of intestinal fixation.

Congenital bronchoesophageal fistula in an adult patient.

INTRODUCTION: Congenital bronchoesophageal fistulas are extremely rare. Symptoms may not be detected before treatment or may be seen intermittently until advanced ages. Treatment is surgical closure of the fistula. CASE PRESENTATION: A 20-year-old female patient with presented complaints of sputum production and cough. A fistula was confirmed between the middle esophagus and the left main bronchus by bronchoscopy. Management is by surgical closure of the fistula via right thoracotomy. The patient had an uneventful recovery. CONCLUSION: Congenital bronchoesophageal fistula malformation can cause long-term respiratory symptoms associated with the fistula and loss of lung parenchyma if left untreated.

Bronchoesophageal fistula diagnosed on modified barium swallow, a unique presentation.

Modified barium swallow (MBS) studies, performed in conjunction with speech pathologists, are routinely performed to assess for aspiration. The narrow field of view over the area of interest limits assessment of pathology in the thoracic esophagus and airways. We report a case of a 79-year-old female with bronchoesophageal fistula diagnosed incidentally after abnormal findings on an MBS initially performed to assess for aspiration.

Endoscopic submucosal dissection-based suture combined with medical adhesive for complicated tuberculous bronchoesophageal fistula: a case report.

Tuberculous bronchoesophageal fistula is a rare complication of tuberculosis. Herein, we report the case of a woman in her late 60s with a choking cough for more than 1 month. Iohexol esophagography revealed a fistulous communication between the esophagus and the right principal bronchus, and gastroscopy documented a fistulous orifice in the esophagus. Endoscopic closure with metal clips failed, and other treatment options, such as extended conservative treatment, covered self-expandable metal stents, and over-the-scope clips were rejected by the patient. Therefore, a combined therapy, endoscopic submucosal dissection-based suture combined with medical adhesive, was performed. Follow-up iohexol esophagography and gastroscopy confirmed fistula closure. During 1 year of follow-up after discharge, the bronchoesophageal fistula did not recur. Endoscopic submucosal dissection-based suture combined with medical adhesive appears to be a practical and feasible solution to complicated tuberculous bronchoesophageal fistula.

Tubercular Bronchoesophageal Fistula in an Adolescent Girl.

Bronchoesophageal fistula is a rare complication of Mycobacterium tuberculosis in children. An adolescent girl who was diagnosed of tubercular mediastinal lymphadenopathy with associated bronchoesophageal fistula at presentation, is reported here. This 16-y-old girl presented with high-grade fever, cough, decreased appetite, weight loss for 3 mo, and breathlessness for 10 d. Chest radiograph revealed hilar lymphadenopathy with bilateral pleural effusion. GA GeneXpert was positive for mycobacterium and rifampicin sensitivity. Despite antitubercular therapy cough persisted and there was a history of dry cough with food intake, especially more on liquids. Bronchoscopy and CECT chest confirmed bronchoesophageal fistula in the right main bronchus just below the carina. Child continued on tube feeding and antitubercular therapy. After completion of intensive phase, child improved with resolution of clinical symptoms and scarring of tract on repeat bronchoscopy. It is concluded that in children with combination of mediastinal lymphadenopathy and persistent cough following intake of food needs careful evaluation for trachea/bronchoesophageal fistula.

Successful Repair of Bronchoesophageal Fistula Through Uniportal Video-Assisted Thoracoscopic Surgery.

This report describes a case of successful repair of bronchoesophageal fistula through uniportal video-assisted thoracoscopic surgery. A 79-year-old female patient presented with persistent cough and aspiration pneumonia. Chest computed tomography and esophagography showed a bronchoesophageal fistula at right side wall of mid to lower esophagus. Esophagogastroduodenoscopy confirmed a fistula in the esophageal diverticulum. Surgical treatment was planned. The operation was performed through uniportal video-assisted thoracoscopic surgery. The patient was discharged 6 days postoperatively without any complication. No recurrence has been observed during 3 months follow-up in the outpatient clinic to date.

Detection of a pinhole-sized bronchoesophageal fistula under bronchoscopic autofluorescence imaging.

Autofluorescence imaging (AFI) is a technique for detecting early-stage lung cancer by amplifying the difference in autofluorescence of the bronchial mucosa. However, there are few reports detailing its other applications. Here, we report the case of a 54-year-old woman with stage IVa esophageal cancer who completed chemoradiation therapy, but developed a bronchoesophageal fistula at the left main bronchus and underwent fasting treatment. Computed tomography confirmed that the fistula had closed; however, she subsequently developed aspiration pneumonia and underwent bronchoscopy for confirmation. Although it was difficult to identify the site of the pinhole bronchoesophageal fistula under white light, AFI could easily identify the fistula and digestive mucus in light magenta. AFI may therefore be worth considering for the detection of pinhole bronchoesophageal fistulas.

Bronchoesophageal fistula secondary to esophageal diverticulum in an adult: a case report and literature review.

Esophageal diverticulum with secondary bronchoesophageal fistula is a rare clinical entity that manifests as respiratory infections, coughing during eating or drinking, hemoptysis, and sometimes fatal complications. In the present study, we describe a case of bronchoesophageal fistula emanating from esophageal diverticulum in a 45-year-old man who presented with bronchiectasis. We summarize the characteristics of this rare condition based on a review of the relevant literature.

Atypical presentation of barium reflux due to bronchoesophageal fistula.

Subtle signs of an abnormal communication from the esophagus to the respiratory tract space via the fistula may be missed and can result in delayed diagnosis. Our case shows an atypical presentation of a fistula during barium swallowing test.

Direct and indirect CT imaging features of esophago-airway fistula in adults.

BACKGROUND: Esophago-airway fistula (EAF) is an abnormal connection between the esophagus and the trachea or a major bronchus. While contrast esophagography remains the primary radiographic tool for the diagnosis of EAF, computed tomography (CT) is often employed in its evaluation. A systematic analysis of CT findings of EAF in adults has not been previously published. The goal of our study is to determine the direct and indirect CT findings of EAF in adults. METHODS: We identified patients with EAF detected on CT at our institution between January 1, 2001 and December 31, 2019, with endoscopic or surgical confirmation. We collected patient clinicopathologic characteristics and assessed CTs for direct and indirect imaging features of EAF in these patients. RESULTS: Twenty-six patients (median age: 56 years; range, 25-79 years; F=13, 50% and M=13, 50%) with confirmed EAF were identified. Half of the patients had an underlying malignancy. On CT, a direct connection between the esophagus and the airway was identified in most cases (22/26; 85%). Common indirect CT findings of EAF included esophageal wall thickening (21/26, 81%), mediastinal fatty stranding (21/26, 81%), airway wall thickening (20/26, 77%), fluid or debris within the airways (17/26, 65%), and focal or diffuse esophageal dilation with air (17/26, 65%). Mediastinal fluid collections were infrequently seen (4/26, 15%), but findings of aspiration or other pneumonia were common (19/26, 73%). CONCLUSIONS: CT plays an essential role in both the primary and secondary evaluation of adult EAF resulting from both malignant and benign etiologies. CT may be the first diagnostic exam to suggest and detect the presence of EAF and may precede clinical suspicion, and it can detect a subset of fistulas not demonstrated on esophagography. There are several direct and indirect imaging findings on CT that can help in the detection of EAF.

Bronchoesophageal fistula secondary to postpneumonectomy like syndrome caused by bilobectomy and postoperative radiation therapy for lung cancer.

Postpneumonectomy like syndrome is a very rare condition and benign bronchoesophageal fistula (BEF) is also uncommon in the adult. Therefore, the probability of occurrence of BEF secondary to postpneumonectomy like syndrome will be extremely rare, and has not been reported yet in the literature. This is the first case report of postpneumonectomy like syndrome combined BEF after bilobectomy and postoperative radiation therapy for lung cancer.

Tuberculous Bronchoesophageal Fistula in Nephrotic Syndrome: A Silent Assassin.

Tuberculosis, a global public health concern, is emerging as an important complication in children with nephrotic syndrome. We report a case of an adolescent with nephrotic syndrome who developed fatal miliary tuberculosis after initiation of steroid therapy, presenting as a bronchoesophageal fistula. The case highlights the importance of maintaining a high index of suspicion prior to starting immunosuppressive therapy in pediatric patients of nephrotic syndrome.

Esophageal bypass surgery as a definitive repair of recurrent acquired benign bronchoesophageal fistula.

BACKGROUND: Acquired benign bronchoesophageal fistula (BEF) is rare and develops as a complication of other diseases, mostly of inflammatory processes and traumas of the chest. The treatment of choice is a surgical repair, which is considered definitive and leads to successful outcomes. However, incidence of recurrence after the primary repair based on limited data is up to 10% and its treatment is challenging. We report a surgical case of a patient with recurrent acquired benign BEF after primary resection and ensuing successful definitive repair with esophageal bypass surgery after temporary esophageal stenting. CASE REPORT: A 46-year-old male was referred to our department with a symptomatic left-sided bronchoesophageal fistula as a complication of severe acute necrotizing mediastinitis that originated from odontogenic abscess. Previously, several cervicotomies and bilateral thoracotomy were performed at an external medical facility to manage the acute condition. We performed resection of the fistula through re-thoracotomy. Postprocedural esophagography demonstrated a recurrence of bronchoesophageal communication. Postinflammatory adhesions excluded further repair through thoracotomy, therefore a stent was introduced in the esophagus for 12 weeks. Thereafter, an esophageal bypass surgery using a substernaly interposed gastric conduit was performed and resulted in an excellent long-term outcome. CONCLUSIONS: Esophageal bypass surgery using a substernaly interposed gastric conduit may be considered if the standard surgical repair of acquired benign bronchoesophageal fistula is not successful or feasible.
