The management of cryptoglandular fistula-in-ano

Abstract

Idiopathic cryptoglandular fistula-in-ano is a common pathological condition. Fistula-in-ano has been managed by a number of surgical techniques, and there is still no consensus regarding the management of this condition. Surgical techniques aim to treat and cure the fistula-in-ano with minimal risk of recurrence or complications, and to maintain patient continence. This article discusses the evidence available to inform the management of idiopathic cryptoglandular fistula-in-ano, and problems that surgeons face because of the lack of high-quality evidence.
