ABSTRACT

Objective: To assess the hypothesis that the frequency of anorectal fistulas is lower in patients with abscesses treated with surgical drainage complemented with antibiotics.
Setting: Third level health care hospital.
Design: Retrospective, descriptive, transversal study.
Statistical analysis: Percentages with summary measures for qualitative variables.
Patients and methods: Forty-one clinical records of patients with a diagnosis of anorectal abscesses treated at the ABC Hospital, Mexico City, from November 1997 to February 2002 were reviewed. The following data were obtained: Identification tag, medical, surgical antecedents of anorectal pathology, such as previous abscesses and/or fistulae, anatomy of the abscess, surgical technique used for the treatment, use of drainage, type of antibiotics, percentage of patients with recurring abscess and/or fistula, and days of intrahospital stay.
Results: Forty one patients fulfilled inclusion criteria; 26 (64%) men and 15 (36%) women. The man:woman ratio was 3:1, average age of 40 years (19-82). All patients were treated with drainage, debridement and marsupialization of the abscesses complemented with antibiotics. Abscesses were classified as: 16 (39%) inter-sphincter, 12 (29%) ischiorectal, 7 (17%) supra-elevated, 5 (12%) postanal, and 1 (2.4%) perianal. Recurrence index of abscesses was 9%, the inter-sphincter abscess was the most frequent (39%). Total percentage of fistula formation was 3%. Intrahospital stay amounted to a mean of 48 h (1-8 days).
Conclusion: Despite the size of the sample, there is a tendency towards a lower incidence to form fistulae and in the recurrence of anorectal abscesses in patients treated with surgical drainage complemented routinely with antibiotics. These results will serve as a basis to perform a prospective, randomized, controlled study.
