An anal abscess is a painful condition that affects many people, often caused by an infection of the small anal glands. Although the abscess itself can be alarming due to the sudden onset of pain, fever, and swelling, what’s even more concerning is that it often develops into another condition—an anal fistula. At Kaizen Fistula Care Clinic, under the expert care of Dr. Samrat Jankar, we frequently manage complex cases of anal abscesses and fistulas and aim to help patients understand why one can often lead to the other. In this blog, we will explore the connection between an anal abscess and fistula formation, what causes this progression, and how early expert intervention can help prevent long-term complications.
Understanding Anal Abscess and Anal Fistula:
What is an Anal Abscess?
- An anal abscess is a localized infection that leads to a collection of pus in the tissues surrounding the anus or rectum. It typically happens when a small gland inside the anus becomes blocked and infected, usually by bacteria from the stool.
Symptoms of an anal abscess include:
- Constant pain in the anal area, often throbbing and worse while sitting
- Swelling and redness near the anus
- Fever and chills
- Discharge of pus or fluid
Most abscesses are superficial and can be drained through minor surgery. However, deeper abscesses may need imaging and more complex intervention.
What is an Anal Fistula?
- An anal fistula is an abnormal tunnel that forms between the infected anal gland (inside the anus) and the external skin near the anus. This tunnel acts as a path for pus and discharge to escape, preventing complete healing.
Symptoms of an anal fistula include:
- Recurrent pain or swelling around the anus
- Persistent discharge of pus or blood
- Skin irritation and itching
- A visible opening or hole near the anus
How Does an Abscess Become a Fistula?
An anal abscess and an anal fistula are not separate diseases — they are often part of the same disease process. Around 50% of patients with an anal abscess will go on to develop a chronic fistula, particularly if the abscess is not fully resolved.
Here’s how it typically happens:
- Infection Begins in the Anal Gland: The process starts when a gland in the anal canal becomes blocked and infected.
- Abscess Formation: Pus accumulates as a result of the infection, forming an abscess.
- Drainage of Abscess: The abscess may rupture on its own or be surgically drained. While this facilitates the immediate symptoms, it doesn’t always eliminate the internal source of infection.
- Tunnel Formation: In some cases, a tract forms between the infected gland & the skin surface to allow pus to escape — this evolves the fistula.
- Chronicity Sets In: The tunnel remains open, leading to chronic drainage, inflammation, and discomfort. This persistent tract is unlikely to heal without surgery.
Why Does Fistula Formation Happen?
- Incomplete Healing: After an abscess is drained, the external symptoms may subside, but the internal infected gland or source may not recover completely. This leads to a persistent tract, resulting in a fistula.
- Persistent Infection: If the source of the infection — usually an anal gland — remains active, it keeps producing pus, and the body forms a fistulous tract as a path of least resistance.
- Delayed or Inadequate Treatment: Sometimes abscesses are treated with only antibiotics or superficial drainage without addressing the deeper infection. This can improve the risk of fistula formation.
- High-Risk Conditions: Patients with Crohn’s disease, tuberculosis, diabetes, or weakened immunity are more prone to developing complex fistulas following an abscess.
Signs That Your Abscess May Have Turned into a Fistula:
If you’ve recently had an anal abscess and are now experiencing persistent pain, swelling, pus discharge, or itching, it’s crucial to see a colorectal specialist in Pune like Dr. Samrat Jankar. Ignoring these symptoms can allow the fistula to become more complex, involving deeper tissues or multiple tracts.
Importance of Early Evaluation by a Fistula Specialist:
At Kaizen Fistula Care Clinic, Dr. Jankar uses advanced diagnostic tools such as:
- MRI Fistulogram
- Endoanal ultrasound
- Proctoscopy and digital rectal exam
These techniques help accurately map the fistula tract, determine its complexity, and plan an effective treatment strategy.
Treatment Options for Anal Fistula:
Treatment relies on the type and complexity of the fistula. Dr. Jankar offers cutting-edge options including:
- Fistulotomy: A traditional surgical method where the tract is opened and allowed to heal naturally.
- VAAFT (Video-Assisted Anal Fistula Treatment): Minimally invasive, with precise visualization and destruction of the fistula tract.
- Laser Fistula Treatment: Painless, scarless, and minimally invasive. Uses laser energy to seal the tract.
- LIFT Procedure: Involves closing the internal opening of the fistula and preserving the sphincter muscles.
- Fistula Plug: A bio-compatible material is placed to close the tract from the inside.
Preventing Fistula After an Abscess:
While not all fistulas can be controlled, early and right management of anal abscesses significantly lowers the risk. Here’s what Dr. Samrat Jankar recommends:
- Never ignore anal pain or swelling
- Seek expert care for any suspected abscess
- Follow post-drainage instructions carefully
- Have regular follow-ups to ensure complete healing
- Get evaluated promptly if any discharge or pain returns
Conclusion:
An anal abscess may seem like a one-time problem, but if not handled carefully, it can progress to a chronic anal fistula — a condition that can disrupt your quality of life and need surgical treatment. Understanding this progression is key to seeking timely care.
