Esophageal tuberculosis is rare among digestive system diseases. We herein present two cases of esophageal tuberculosis. One patient presented with a choking sensation and pain in the chest, and the other presented with loss of appetite and emaciation. Both patients had an esophagomediastinal fistula, underwent endoscopic ultrasonography and fine-needle aspiration, were clinically diagnosed with esophageal tuberculosis, received antituberculosis treatment, and exhibited clinical improvement. These two rare cases suggest that the possibility of esophageal tuberculosis should be considered in patients with an esophagomediastinal fistula. Endoscopic ultrasonography and fine-needle aspiration can be performed to assist the diagnosis. Good clinical results can often be achieved with timely antituberculosis treatment.

Esophageal tuberculosis is one of the rarest forms of tuberculosis with higher incidence in immunocompromised cases. In majority of cases it is seen associated with esophagomediastinal and esophagotracheal fistulas. Diagnosis is established with the help of esophagoscopy followed by histopathology and microbiological analysis of biopsy sample. Treatment with antituberculous therapy alone is sufficient in majority of cases, however surgical management is mandatory in severe and non resolving cases. We thereby report an interesting case of esophagomediastinal fistula presenting as drug resistant tuberculosis with retroviral disease.

The aim of the present study was to investigate the survival and prognostic factors of patients who were with advanced esophageal squamous cell carcinoma (ESCC) and developed an esophageal fistula. The data from 221 patients with advanced ESCC developed esophageal fistula from January 2008 to December 2017 at the Harbin Medical University Cancer Hospital was retrospectively analyzed. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated by the Cox proportional hazard models. The median survival time after a diagnosis of the esophageal fistula was calculated using the Kaplan-Meier method. We found that the pathogens infected by patients are common bacteria in nosocomial infection. Besides, the incidence rate of esophagomediastinal fistula was the highest (54.2%) in the lower third of the esophagus. Kaplan-Meier analysis revealed a median survival time of 11.00 months and a median post-fistula survival time of 3.63 months in patients who developed esophageal fistula in advanced esophageal cancer. In the univariate analysis, gender, therapies for ESCC before the development of fistula, type of esophageal fistula, treatment of esophageal fistula and hemoglobin (Hb) level were the factors with significant prognostic value. Gender, type of esophageal fistula and Hb level were identified as independent prognostic factors in further multivariate analysis. In summary, our study demonstrated that several factors are significantly related to patients with esophageal fistula and should be concerned about in clinical practice.

BACKGROUND: Acute mediastinitis with esophageal perforation is a very fatal condition and must be treated promptly. Esophagomediastinal fistula is a rare complication of acute mediastinitis with esophageal perforation. There are many treatment options such as surgery or endoscopic treatment, but it is most important to start treatment immediately.
METHODS: A 69-year-old female presented with chest pain and fever. Contrast enhanced chest computed tomography was compatible with acute mediastinitis and esophageal perforation. Esophagography revealed esophagomediastinal fistula in the upper esophagus. Endoscopic clipping with fibrin was failed and endoscopic vacuum therapy (EVT) was not effective for esophagomediastinal fistula. We performed the successful transcatheter embolization of the esophagomediastinal fistula with N-butyl cyanoacrylate (NBCA) glue.
CONCLUSIONS: There are many considerations in the treatment of acute mediastinitis with esophageal perforation, but surgery is the mainstay of treatment. Recently non operative management is appropriate in certain well-defined situations. Like our case patients, non-operative management may be considered if the diagnosis is delayed and the surgical treatment period is missed. Currently, endoscopic treatment such as covered stenting, clipping and application of fibrin glue are useful and a less invasive rather than surgical treatment. However, if endoscopic or surgical procedure are not possible, we considered transcatheter NBCA glue embolization.
CONCLUSIONS: Transcatheter embolization with NBCA glue was proven to its effectiveness as an alternative therapeutic option in the treatment of esophagomediastinal fistula which endoscopic or surgical treatment are impossible or fails.

BACKGROUND: Esophagomediastinal fistula is a very rare complication of tuberculosis in otherwise healthy adults, and mediastinal bronchial artery aneurysm is even rarer. In this case report, we describe a rare case of tuberculosis complication that presented with acute upper gastrointestinal (GI) bleeding. It also highlights the benefits of chest computed tomography (CT) as an excellent adjunct diagnostic tool to endoscopy and bronchoscopy and the role of trans-arterial embolization as a minimal invasive therapy alternative to surgery.
METHODS: A 19-year-old medically free male patient presented with acute multiple episodes of hematemesis for 1 d. Upper GI endoscopy, bronchoscopy, and chest CT with IV contrast confirmed esophagomediastinal fistula with mediastinal bronchial artery aneurysm. After resuscitating patient with IV fluid and blood product transfusion, trans catheter embolization was performed for mediastinal bronchial artery aneurysm.
CONCLUSIONS: We successfully treated a patient with acute upper GI bleeding due to tuberculous esophagomediastinal fistula and mediastinal bronchial artery aneurysm using transcatheter coil embolization.
