Introduction: Anal fi stula as abnormal communication between the anorectal canal and the skin is defi ned and is a phase in an anal abscess acute chronic infectious process. Most have anal fi stulas lar criptoglandu- origin. After an anorectal abscess, 7-40% of cases progress to a chronic phase manifests anal fi stula. Fistulas are classifi ed into simple and complex. The sim- ple are defi ned as intersphincteric fi nterianos journeys or transesterifi cation in which the inner hole is identifi ed, below the anorectal ring.

Material and methods: Records of all patients who attended the Consultation of Coloproctology Clinic in the period between 1 January 2008 and 31 December 2012 were reviewed. All patients who were seen for the fi rst time and had an initial diagnosis of anal fi stula, were included, discarding those patients diagnosed with recurrent anal fi stula. The data were collected in a database in order to perform statistical tests.

Results: A total of 871 records were reviewed, of which 87.72 % (n = 764 ) were male and 12.28 % (n = 107) female, with a male-female ratio of 7:1. The mean age was 43.02 years ± 11.76, with an age range of 17-95 years. The number of patients operated on was 544. It was noted that the most common types of fistula were inter-sphincter (over 56%), followed by transsphincter with 33.7 % (23 % upper transsphincteric and 10.7 % lower transsphincteric).

Conclusions: Anal fistula is a common condition in the Coloproctology Clinic in a tertiary hospital. It is more common in men, with a mean age of 43 years. The fi stula seen more often is the inter-sphincteric fi stula, followed by upper transsphincteric. Our results are similar to those found in the international literature.
