Anal fistula is the medical term for an infected tunnel that develops between the skin and the muscular opening at the end of the digestive tract anus. Most anal fistulas are the result of an infection that starts in an anal gland. This infection results in an abscess that drains spontaneously or is drained surgically through the skin next to the anus.
Predictors of Outcome for Anal Fistula Surgery. Arch Surg. We evaluated age, sex, previous operation, fistula type, number of fistula tracts, horseshoe fistula, and intervention type to determine their independent influence on outcomes.

SUMMARY : Perianal fistula, usually has a criptoglandular etiology, developing from a perianal abscess and communicating the anal mucosa with the perianal skin. The surgical techniques and post-operative outcome have been analysed. Eighty percent were submitted to fistulectomy as the first surgical treatment. There were reoperations in 80 patients.
