PEREZ ESCOBEDO, Sergio Ulises; JIMENEZ BOBADILLA, Billy  e  VILLANUEVA HERRERO, Juan Antonio. Risk factor associated to the development of anal fistula. Cir. gen [online]. 2013, vol.35, n.1, pp.25-31. ISSN 1405-0099.

Objective: To determine the risk factors associated to the development of anal after an anal abscess. Setting: General Hospital of Mexico (third level health care center). Design: Case-controls study. Statistical analysis: Univariate analysis. Patients and methods: The study comprised 250 patients observed in the period of May 2009 to January 2012 assessed in the outpatient clinic of the Coloproctology Unit, with a diagnosis of anal abscess and three months or more of follow-up. Analyzed varaibles were: age, ocupation, diabetes mellitus, smoking, alcohol consumption, previous antibiotics and after the drainage, type of evacuation according to the Bristol scale, anal reception, time of abscess evolution, and site where drainage of the abscess was performed (outpatient clinic, surgery room, or spontaneously). Results: Of the 250 patients with an anal abscess treated with a simple drainage, 103 (41.2%) developed an anal. Results of the univariate analysis did not reveal any statistical significance for any of the studied variables. Conclusion: We did not identify any risk factor in this paper to be able to determine which patients can develop an anal after an anal abscess event.
