Fistula-in-Ano with Broomsticks: An Unusual Etiology.

Fistula-in-ano is caused by idiopathic infection of the cryptoglands located in the anal intersphincteric plane when the resultant cryptoglandular abscess drains internally and externally. It is a common surgical disease that responds well to surgical intervention. In cases of recurrent non-healing fistula-in-ano, an underlying cause should be suspected and searched for.
