INTRODUCTION: The incidence of perianal fistulas is high, and this condition has a profoundly negative impact on patients' quality of life. The problem is greater when the fistula tract is high because treatment is necessarily complex (limited surgery may lead to recurrence, while aggressive surgery is associated with higher rates of faecal incontinence). To achieve a balance between these two options, we suggest that complex fistulas should be treated by sealing the tract with platelet-rich fibrin. Our objective is to evaluate the medium- to long-term results obtained from the treatment of complex perianal fistulas by sealing with platelet-rich fibrin. MATERIAL AND METHODS: Prospective longitudinal multicentre study involves three colorectal surgeons working at three hospitals. The study period was October 2010 to June 2013, during which a total of 60 patients were treated for complex fistulas. In all cases, the intervention consisted of curetting the fistula tract, sealing it with platelet-rich fibrin and closing the internal orifice. We evaluated the clinical outcomes (clinical examination and pelvic magnetic resonance (MRI)) and the quality of life results, both general (SF-36) and gastrointestinal (GIQLI questionnaire) in periodic reviews during consultation. RESULT: The median follow-up period was 24 months (11-43 months), during which in 40 patients (66.66 %) the fistulas remained closed, with a zero rate of faecal incontinence. The results of the quality of life questionnaires are comparable (indeed, they are better in some items for the cured patients) to those of the reference population. CONCLUSION: In our opinion, this procedure is safe and its results are promising in terms of clinical outcome and medium- to long-term quality of life.
