What is the difference between Fistulotomy and Fistulectomy?
A fistulectomy involves complete excision of the fistulous tract, thereby eliminating the risk of missing secondary tracts and providing complete tissue for histopathological examination. A fistulotomy lays open the fistulous tract, thus leaving smaller unepithelized wounds, which hastens the wound healing.

Which is true of goodsall rule?
Goodsall’s rule states that a fistula with the external opening anterior to an imaginary transverse line across the anus has its internal opening at the same radial position and for an external opening posterior to this line, the internal opening is in the midline posteriorly with a horse-shoe track.
How long is fistulotomy recovery?
