Ano-rectal Fistula

Information about ano rectal fistula

An ano-rectal fistula, also known as an anal fistula, is an abnormal connection between the epithelialized surface of the anal canal and the perianal skin. This condition is usually the result of an anorectal abscess that has drained spontaneously or has been surgically drained but failed to heal completely. Here is an overview of key information regarding ano-rectal fistulas:


Anorectal Abscess: The most common cause, where an infection in the anal glands leads to an abscess, which, if not properly healed, forms a fistula.
Crohn’s Disease: Chronic inflammation from this inflammatory bowel disease can lead to fistula formation.
Trauma: Injury to the anal or rectal area can result in a fistula.
Radiation: Radiation therapy for cancer can sometimes lead to fistulas.
Infections: Conditions like tuberculosis, sexually transmitted infections, or actinomycosis can cause fistulas.
Cancer: Rectal or anal cancer may also be associated with fistula formation.


Recurrent Abscesses: Frequent abscesses in the same area.
Pain and Swelling: Pain around the anus, especially when sitting, moving, or during bowel movements.
Discharge: Persistent discharge (pus or blood) from an opening around the anus.
Irritation and Redness: Skin irritation around the anus due to constant discharge.
Fever: Occasionally, fever may be present, indicating an ongoing infection.


Physical Examination: A thorough examination of the anal region by a healthcare provider.
Anoscopy: A procedure where a small, rigid scope is inserted into the anus to visualize the fistula.
Imaging Studies: MRI or endoanal ultrasound may be used to determine the fistula’s tract and complexity.
Fistulography: An X-ray procedure where a contrast dye is injected into the fistula to outline its course.


Surgical Options:
Fistulotomy: The most common procedure where the fistula tract is cut open to heal as a flat scar.
Seton Placement: A surgical thread (seton) is placed to help drain the fistula and allow it to heal.
Advancement Flap Procedures: Tissue is moved to cover the internal opening of the fistula.
LIFT Procedure (Ligation of Intersphincteric Fistula Tract): Involves ligating the fistula tract between the internal and external sphincters.
Non-Surgical Options:
Fibrin Glue: A biocompatible glue injected into the fistula tract to close it.
Bioprosthetic Plug: A plug made of biocompatible material to close the fistula.


The prognosis for patients with an anal fistula depends on the complexity of the fistula and the underlying cause.
Simple fistulas have a high rate of cure with appropriate surgical treatment.
Complex fistulas, especially those associated with Crohn’s disease or other systemic conditions, may require more extensive treatment and have a higher risk of recurrence.


Prompt treatment of anorectal abscesses to prevent fistula formation.
Managing underlying conditions like Crohn’s disease effectively.
Maintaining good anal hygiene to prevent infections.
If you suspect you have an anal fistula, it is important to seek medical advice promptly for proper diagnosis and treatment.

Homeopathic approach for ano rectal fistula

Homeopathy offers a range of remedies that aim to treat ano-rectal fistulas by stimulating the body’s natural healing processes. While these remedies are used by some practitioners and patients, it’s important to note that the efficacy of homeopathy is a subject of debate within the medical community, and conventional treatments are often recommended for conditions like fistulas due to their potentially serious nature.

Here are some homeopathic remedies commonly suggested for ano-rectal fistulas:

Common Homeopathic Remedies

Silicea (Silica)
Indications: Useful for fistulas that are associated with recurrent abscesses, pus formation, and offensive discharge.
Symptoms: May include hard lumps, slow healing wounds, and feeling cold or chilly.
Calcarea sulphurica

(Calcium Sulphate)
Indications: Often recommended for fistulas with yellow, purulent discharge and persistent drainage.
Symptoms: Associated with slow-healing wounds and glandular swellings.
Hepar sulphuris calcareum

(Calcium Sulphide)
Indications: Helps in cases where there is intense pain, especially from the slightest touch or exposure to cold air.
Symptoms: Marked by the formation of pus and a tendency for the abscess to burst open.
Myristica sebifera

(Brazilian Ucuba)
Indications: Known as the “homeopathic knife,” it is used for promoting suppuration and expelling pus.
Symptoms: Effective in treating abscesses and boils, and may help hasten the formation of pus.
Berberis vulgaris

Indications: Used for fistulas associated with urinary and digestive complaints.
Symptoms: Symptoms may include sharp, stitching pain, and sensations of bubbling or bursting.
Paeonia officinalis

Indications: Particularly effective for fistulas and hemorrhoids, especially when there is severe pain during and after bowel movements.
Symptoms: Often accompanied by intense burning and itching.

Homeopathic Treatment Approach

Constitutional Treatment: A homeopath may consider a patient’s overall health, lifestyle, emotional state, and specific symptoms to prescribe a constitutional remedy that suits the individual’s unique condition.
Symptomatic Relief: Remedies are chosen based on specific symptoms presented by the patient, aiming to provide relief from pain, discharge, and inflammation.
Follow-up and Monitoring: Regular follow-ups are important to monitor the progress and make adjustments to the treatment as needed.
Consultation with a Professional: It’s crucial to consult with a qualified homeopathic practitioner to receive a personalized treatment plan.
Combination with Conventional Treatment: In some cases, homeopathy may be used as a complementary approach alongside conventional medical treatments. Always inform your healthcare provider about any homeopathic remedies you are using.
Monitoring for Complications: Due to the potential for complications with fistulas, such as infection or progression to more serious conditions, close monitoring by a healthcare professional is important.
While some people find relief with homeopathic remedies for ano-rectal fistulas, it’s essential to approach treatment with caution. Homeopathy should not replace conventional medical treatment, especially for conditions that may require surgical intervention. Always seek professional medical advice for diagnosis and treatment options tailored to your specific needs.
