Clinical profile and management of tuberculous bronchoesophageal fistula
Abstract
Background and Objectives: Tracheoesophageal/bronchoesophageal fistula is a rare clinical condition, and occurs due to a variety of disease processes. This report describes the clinical profile, management, and outcome of bronchoesophageal fistulas due to tuberculosis in five patients. Patients and Methods: Patients diagnosed with esophageal tuberculosis over the last eight years were included. Details regarding the demographics, symptomatology, barium swallow, upper GI endoscopy, with biopsy and high resolution computed tomography of the chest were recorded for patients with tracheoesophageal fistula. The diagnosis was confirmed by acid fast bacilli (AFB) positive fluid aspirate/brush cytology from the fistula, lymph node biopsy showing caseous necrosis or AFB bacillus and tissue tuberculosis culture and polymerase chain reaction (PCR). Results: There were five patients (four males and one female) with a mean age of 43.8 ± 17 years (range, 17 to 59 years). The mean duration of symptoms was 38 ± 7 days. The most common symptom was coughing on swallowing followed by dysphagia. Two patients had concomitant pulmonary tuberculosis; two had human immunodeficiency virus (HIV) infection, and one was a post-renal transplant. The diagnosis of tuberculosis was established in all five patients with esophageal cytology, lymph node biopsy, and tissue tuberculosis PCR. All the patients were successfully treated with a combination of antituberculous drugs (five patients), glue application on fistula (one patient), Percutaneous endoscopic gastrostomy (PEG) tube insertion (three patients), and surgery (one patient). Conclusions: Tuberculous bronchoesophageal fistula is a rare complication and can be successfully managed predominatly with a combination of antituberculous treatment, PEG tube placement, and rarely surgery.
