Abstract Objective Tuberculosis fistula in ano, though less encountered, is an important clinical entity in developing countries like India. Diagnosis of TB fistula is a challenge despite of advances in diagnostic modalities and it depends upon both local and systemic clinical presentation. This prospective study aimed at to substantiate the importance of clinical diagnosis as well as medical management of tubercular fistula by antitubercular drugs. Methods and results 25 patients of fistula in ano suspected to be of tubercular origin underwent histopathology of fistulous tracks and an 8 week therapeutic trial of antitubercular treatment after getting an informed consent. Though biopsy showed positive evidence of tubercular pathology only in 52% cases, therapeutic trial showed improvement in local and systemic features in 23 (92%) cases. Of these 23 cases, 3 were cured after 18 months of anti tubercular treatment and 18 showed cure after 24 months of anti tubercular treatment while 2 cases withdrew from the study at 12 and 14 months respectively due to adverse drug reactions though their fistulous symptoms were relieved. Conclusion Meticulous clinical evaluation plays a vital role in diagnosis of tubercular fistula in addition to other diagnostic methods. Anti tubercular treatment is the mainstay of treatment in tubercular fistula with a minimum duration of 18-24 months owing to the recurrent and relapsing nature of disease.
