Diagnosis of Fistula-in-Ano: An Innovative Approach

Arun Kumar Dwivedi


Fistula-in-ano is a common condition that occurs due to inadequate drainage or spontaneous bursting of a perianal abscess. It often recurs after best of surgery usually because of infection that was missed at surgery. Preoperative imaging can help identification of infection that would have otherwise gone unidentified. In particular, magnetic resonance imaging (MRI) findings have been claimed to influence surgery and markedly diminish the chance of recurrence according to recent reports. But in countries like India, this is not possible for majority of patients to afford MRI because of cost effectiveness and non-availability of MRI facility at common centers. Therefore, still fistulography is commonly used for preoperative imaging of fistula-in-ano. In the present work, fistula-in-ano and its imaging techniques are described, with an emphasis on fistulography by Deshpande technique.
