The medical treatment of a tuberculous tracheo-oesophageal fistula

Esophagomediastinal Fistula Closed Endoscopically in a Young Patient With Tuberculosis and Human Immunodeficiency Virus

Tuberculosis is a primary lung disease that can spread to the lymph nodes, vertebrae, and gastrointestinal tract. The esophagus can be affected by mediastinal lymphadenitis, mostly in immunocompromised patients, leading to the formation of esophagomediastinal fistulas. They can cause dysphagia, pleuritic chest pain, and choking coughs from recurrent aspiration. The treatment is surgery but endoscopic interventions using over-the-scope endoclips, stents, medical adhesives, and sutures are successful alternatives. We present a case of an esophagomediastinal fistula in a patient with tuberculosis and human immunodeficiency virus that was successfully treated with through-the-scope endoclips.

Atypical presentation of acquired tracheo-oesophageal fistula in an adolescent girl with pulmonary tuberculosis

We report a case of an adolescent girl presenting with acute respiratory distress syndrome (ARDS) requiring mechanical ventilation. Initial presentation during the ongoing COVID-19 pandemic was compatible with multisystem inflammatory response in children associated with COVID-19 (MIS-C). Subsequently a diagnosis of tuberculosis was made. During ventilation, she developed significant abdominal distension which was not relieved with nasogastric decompression. There was a high index of suspicion of bronchoenteric fistula. Bronchoscopy with adjunct oesophagoscopy demonstrated tracheo-oesophageal fistula (TEF). The classical presentation of TEF has been masked by onset of ARDS. During the pandemic the diagnosis of tuberculosis in high-burden countries decreased for multiple reasons leading to development of complications which are often confused with MIS-C. While diagnosing MIS-C, maintaining a high level of suspicion for concomitant or alternative aetiologies is essential.

Gastrointestinal Tuberculosis

Gastrointestinal tuberculosis (TB) is a fascinating disease which can be observed both in the clinical context of active pulmonary disease and as a primary infection with no pulmonary involvement. It represents a significant clinical challenge because of the resurgence of TB as well as the diagnostic challenges it poses. A high clinical suspicion remains the most powerful tool in an era of medicine when reliance on diagnostic technology increases. Antimicrobial therapy is the mainstay of therapy, but surgical and endoscopic interventions are frequently required for intestinal TB. Gastrointestinal TB is truly the "great mimic" and continues to require the astute clinical acumen of skillful clinicians to diagnose and treat.

Tuberculosis presenting as bronchoesophageal fistula

We report a case of bronchoesophageal fistula associated with tuberculosis. A 25 year old woman presented to us with 3 month history of cough worsening with deglutition. Radiological examination revealed mediastinal lymphadenopathy and bronchoscopy with esophagoscopy confirmed the presence of fistulous communication with features of endobronchial tuberculosis. Histological examination of bronchial biopsy specimen showed non necrotic granuloma with the PCR positive for Mycobacterium tuberculosis in her bronchial secretions. She was begun on antituberculous treatment and became asymptomatic after 2 months. Bronchoscopy done during follow up after 4 months showed normal bronchial lumen with disappearance of fistulous tract. Imaging showed resolution of lung lesions.

An Interesting Case of Dysphagia in a HIV Patient

Oesophageal tuberculosis is a rare disease. Tuberculosis (TB) can cause dysphagia due to oesophageal ulcers, Tracheo-Oesophageal Fistulas (TOFs) and an extrinsic compression which is caused by the mediastinal lymph nodes. A 33-year-old gentleman was admitted to our hospital for the evaluation of fever, dysphagia and cough. His chest X-ray was suggestive of miliary tuberculosis. A CT scan of his chest revealed miliary tuberculosis, mediastinal lymphadenopathy and pneumomediastinum. His sputum AFB (acid-fast bacilli) test was positive. An upper gastrointestinal endoscopy revealed a large ulcer in the oesophagus with a fistulous opening which was suggestive of a tracheo-oesophageal fistula. A biopsy from the ulcer was positive for AFB. The test for HIV-1 was positive. A nasogastric feeding tube was placed and the Anti Tubercular Therapy ( ATT) was started. The main aim of this case report is to sensitize the clinicians about the fact that Tuberculosis can present with dysphagia, especially in HIV patients.

Endotracheal tuberculous granuloma formation following endobronchial ultrasound transbronchial needle aspiration

Endobronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA) is a useful and safe diagnostic test. We herein report a case of endotracheal granuloma formation that occurred after EBUS-TBNA in a 73-year-old woman. The patient was admitted due to coughing and dyspnea after 70 days of antituberculous therapy for mediastinal lymphadenitis. Computed tomography revealed decreases in the size of the lymph nodes with a new mass protruding into the tracheal lumen. The mass originated from the right paratracheal area, which was a previous puncture site. This case suggests that clinicians should pay attention to complications because tuberculosis can produce new granulomas via the sinus tract after EBUS-TBNA.

Dysphagia due to tuberculosis

OBJECTIVE

Dysphagia due to tuberculosis is rare in both the developing countries with high prevalence rates and the western population following the recent upsurge linked to the AIDS and immigration.

AIM

To study tuberculosis as an aetiological factor in the causation of dysphagia and to evaluate the outcome of anti-tubercular treatment and surgical results in these patients.

METHODS

Retrospective review of experience with 14 cases of dysphagia due to tuberculosis encountered between 1996 and 2003.

RESULTS

The duration of symptoms ranged between 3 and 18 months. All of them underwent oesophagogastroscopy, barium swallow, fiberoptic bronchoscopy and CT scan of the chest. The aetiology was subcarinal node enlargement in seven, tracheo-oesophageal fistula in four, oesophageal ulcer in two and cervical node suppuration in one. Tuberculous involvement was confirmed by pathological examination in all patients. All of them received anti-tuberculous therapy. Seven patients required surgery, transthoracic repair of tracheo-oesophageal fistula in four patients, one patient required subcarinal node excision and two needed abscess drainage. There were no mortalities and there was complete relief of dysphagia in all of them.

CONCLUSIONS

Tuberculosis as a causative factor for dysphagia should be considered in regions with high incidences of tuberculosis and in immunocompromised patients. Treatment with anti-tuberculous therapy is effective. Surgery is required only for complications of tuberculosis.

Tuberculous fistula of the esophagus

BACKGROUND

Tuberculous involvement of the esophagus has been extremely rare during the past 40 years. It will be, however, more frequently encountered in the future, as the number of immunocompromised patients is growing. This condition is usually secondary to infection in other thoracic sites, such as lungs, larynx, or mediastinum. The diagnosis is difficult if the suspicion of tuberculosis is not raised. Dysphagia and cough after ingestion of fluids and food are common symptoms without any other specific signs in these patients. Diagnosis is based on combination of esophagography, esophagoscopy, bronchoscopy, and computed tomographic scan.

METHODS

We present 3 patients with tuberculous fistulas of the esophagus. Two of our 3 patients were treated successfully with the combination of operation and antituberculous chemotherapy. Fistulas were resected and closed directly. Suture lines were secured with pedicled pleural flaps.

RESULTS

Both patients who underwent operation recovered without complications. One patient died without definitive diagnosis and treatment.

CONCLUSIONS

Treatment of tuberculous fistulas consists of operation and antituberculous chemotherapy, although antituberculous medication alone has been suggested to be effective if the diagnosis is early. However, operation is usually necessary to establish the correct diagnosis. Therefore, we believe that if the cause of the esophageal fistula cannot be verified, thoracotomy should be performed. If the fistula is left untreated the consequences are usually fatal.
