ABSTRACT

According to the cryptoglandular theory, more than 95% of anal abscesses are produced by infection of the anal glands. Objective: The goal of the present investigation is to determine the frequency of anal fistula after drainage of the anal abscess at clinic. Material and methods: It is a retrospective, observational and transversal study, performed at the Coloproctology Unit of the Gastroenterology Service in the General Hospital of Mexico City, between January 2000 and December 2002. Results: 112 patients were included between 15 and 80 years old. The higher incidence was in the third and fourth decades of age with predominance in the male in a relation of 4:1. Localization of the abscess was perianal in 85 patients (75.89%), ischiorectal in 24 (21.43%) and intersphincteric in 3 (2.68%). There was no suprasphincteric abscess in this series. In 74 of this patients (66.07%) an anal fistula developed after the surgical drainage in a follow up of 6 months or more. Conclusions: The drainage of the anal abscess is a procedure that can be done on ambulatory basis in the office, although 66.07% of anal abscesses treated with just drainage in this series developed an anal fistula.
