Causes and Risk Factors of Perianal Fistula
Perianal fistulas typically develop as a consequence of an anal abscess that has not healed properly. Some of the most common causes and risk factors include:
- Previous anal abscesses.
- Inflammatory bowel diseases, such as Crohn’s disease or Ulcerative Colitis.
- Sexually transmitted infections.
- Previous surgeries in the anal area.
- A weakened immune system.
- Poor anal hygiene, which may lead to bacterial infections.
- Trauma to the perianal area, such as untreated wounds or fissures.
Identifying the underlying cause is key to determining the best treatment and avoiding recurrences.
Diagnosis of Perianal Fistula
The diagnosis of a perianal fistula is based on:
- Physical examination, during which the specialist inspects the affected area.
- Endoanal ultrasound, to evaluate the path of the fistula.
- MRI (Magnetic Resonance Imaging), in complex cases, to identify the extent of the fistulous tract.
The sooner a precise diagnosis is made, the better the chances of effective treatment and recovery.
Advanced Treatments for Perianal Fistula in Moncloa-Aravaca
At Centro Pad, we offer advanced and minimally invasive techniques to treat perianal fistulas, reducing pain and speeding up recovery.

Laser Treatment for Perianal Fistula
Laser therapy is a minimally invasive alternative that allows treatment of the fistula without the need for large incisions. Its benefits include:
- Controlled closure of the fistulous tract.
- Less postoperative pain and lower risk of infection.
- Faster recovery and reduced medical leave.
- Less bleeding and minimal visible scarring.
Other Techniques
In addition to laser treatment, at Centro Pad we offer other advanced approaches for perianal fistula, such as:
- Seton placement, which helps to progressively drain the fistula.
- Advancement flap techniques, ideal for recurrent or complicated cases.
- Fistulectomy, a resection technique that promotes natural healing.
When Is Surgery Necessary for Perianal Fistula?
While some fistulas can be treated with non-invasive methods, surgery is often the best option to prevent complications. Some signs that may indicate the need for surgical intervention include:
- Persistent and intense pain that doesn’t improve with medication.
- Continuous discharge of pus or blood, indicating an active infection.
- Recurrent fistulas that haven’t healed with previous treatments.
- Presence of multiple fistulous tracts, which may require a more precise intervention.
- Difficulty maintaining hygiene and constant discomfort in the perianal area.
At Centro Pad, we offer a personalized evaluation to determine the most appropriate treatment for your case.
