Local Anaesthesia for Anal Fistula Track Probing
If a surgeon wants to completely eradicate the Anal fistula, then it is necessary to find its course and internal opening. It is better performed by inserting a malleable probe in the track. It can only be done by instilling topical or local anaesthesia. Local anaesthesia in the form of 1% Lignocaine is better as it abolishes all sensations of pain. Probing can be performed with ease thereafter.
