Completed
- Conditions
- Fistula in Ano
- Interventions
- Procedure: surgical procedures commonly done for anal fistula
- Registration Number
- NCT04588701
- Lead Sponsor
- University of Michigan
- Brief Summary
Anal fistula is a common condition with a wide variety of clinical presentations, which can make evaluation and treatment challenging and surgical outcomes uncertain. This study was undertaken to identify lessons learned in the surgical treatment of 483 patients over a 20- year period leading to a pragmatic approach to treatment of this condition.
- Detailed Description
The wide array of variations of anal fistulas makes them challenging both to classify and to treat. The aim of the study is to determine if a systematic approach to their evaluation and surgical treatment, regardless of how one wishes to classify them, can be based on careful assessment of sphincter length and of the anatomical and etiological characteristics of the fistula.
