Lateral internal sphincterotomy is the preferred method of surgery for persons with chronic anal fissures, and is generally used when medical therapy has failed. [1] It is associated with a lower rate of side effects than older techniques such as posterior internal sphincterotomy and anoplasty, [3] and has also been shown to be superior to topical glyceryl trinitrate (GTN 0.2% ointment) in ...
Anal sphincterotomy is a surgical procedure that involves treating mucosal fissures from the anal canal/sphincter. [ 1 ] [ 2 ] The word is formed from sphincter + otomy (to cut, to separate). [ 3 ]

In 1993 Matos et al. described a technique of total anal sphincter preservation in high fistula in ano, which is based on the concept of excision of intersphincteric anal gland infection through the intersphincteric approach. [3] This novel technique was also documented in Corman’s textbook of colon and rectal surgery. [4]
Goodsall's rule relates the external opening (in the perianal skin) of an anal fistula to its internal opening (in the anal canal). It states that if the perianal skin opening is posterior to the transverse anal line, the fistulous tract will open into the anal canal in the midline posteriorly, sometimes taking a curvilinear course.
