Your Guide to Navigating Anal Fistula

At a Glance

An anal fistula is a small tunnel connecting an infected anal gland to the skin around the anus. It is a highly treatable condition that typically requires advanced imaging like a pelvic MRI for mapping, followed by targeted surgical treatments such as a fistulotomy or seton placement to cure the tract while protecting bowel control.

Welcome to your comprehensive guide on anal fistulas. Receiving this diagnosis can be a frightening and isolating experience, but understanding your condition is the first step toward effective treatment and healing.

An anal fistula is a small tunnel connecting an infected gland inside the anal canal to an opening on the skin around the anus. While it can cause significant physical discomfort and emotional distress, it is a highly treatable condition.

This guide is designed to empower you with evidence-based information, helping you navigate your diagnosis, evaluate your treatment options, and partner effectively with your medical team. Please explore the sections below to learn more about each phase of your care journey:

Common questions in this guide

What is an anal fistula?
An anal fistula is a small tunnel that connects an infected gland inside the anal canal to an opening on the skin around the anus. It often causes discomfort and requires medical evaluation to properly treat and heal.
How is an anal fistula diagnosed and mapped?
Doctors use advanced imaging, primarily a pelvic MRI, as the gold standard to accurately map the fistula tunnel. This detailed imaging helps them understand the fistula's path through the sphincter muscles and plan the safest surgical approach.
What surgical treatments are available for an anal fistula?
Treatment depends on the fistula's complexity and location. Options range from a simple fistulotomy to sphincter-sparing techniques like the LIFT procedure and advancement flaps, which are designed to protect your bowel control.
What is a seton and why is it used for a fistula?
A seton is a piece of surgical material placed through the fistula tract to keep it open and draining. It acts as a safety net to clear infection and protect your sphincter muscles, often used as a step before a more permanent surgery.
How does Crohn's disease affect anal fistula treatment?
For patients with Crohn's disease, treating an anal fistula requires a highly specialized approach. It typically involves a close partnership between a gastroenterologist and colorectal surgeon, combining biologic medications to control inflammation with careful surgical intervention.

Questions to Ask Your Doctor

Curated prompts to bring to your next appointment.

  1. 1.How many complex anal fistula surgeries do you perform each year, and what is your approach to preserving continence?
  2. 2.Do you routinely work with a multidisciplinary team, such as a gastroenterologist, if I have signs of an underlying condition like Crohn's disease?
  3. 3.What is the communication process like with your office if I have a post-operative concern, such as increased pain or bleeding?
