Anal fistula surgery is a commonly performed procedure.The diverse anatomy of anal fistulae and their proximity to anal sphincters make accurate preoperative diagnosis essential to avoid recurrence and fecal incontinence.Despite the fact that proper preoperative diagnosis can be reached in the majority of patients by simple clinical examination,endoanal ultrasound or magnetic resonance imaging,on many occasions,unexpected findings can be encountered during surgery that can make the operation difficult and correct decision-making crucial.In this article we discuss the difficulties and unexpected findings that can be encountered during anal fistula surgery and how to overcome them.
