What is the Difference Between Fistula and Pilonidal Sinus?
🆚 Go to Comparative Table 🆚A fistula and a pilonidal sinus are both abnormal tracts or channels through the tissue, often associated with abscesses and drainage in the anal region. However, there are key differences between the two conditions:
- Tract Direction: In a pilonidal sinus, the tract leads to a collection of hair and debris, while the tract of a fistula extends from the skin all the way to the anal wall.
- Location: A pilonidal sinus is a small tunnel or cavity that usually forms at the top of the crease between the buttocks. An anal fistula, on the other hand, is a connection between the anal canal and the skin around the anus.
- Cause: Pilonidal sinuses are often caused by ingrown hairs or hair fragments that penetrate the skin and become infected, leading to the formation of a cyst-like structure. Anal fistulas are typically caused by an abscess or infection in the anal glands.
In rare and severe cases, a pilonidal sinus can cause a fistula, a condition known as pilonidal fistula-in-ano. Treatment for both conditions may involve surgery, and it is essential to seek immediate medical attention if you suspect you have either a pilonidal sinus or an anal fistula.
Comparative Table: Fistula vs Pilonidal Sinus
Here is a table comparing the differences between a fistula and a pilonidal sinus:
Feature | Fistula | Pilonidal Sinus |
---|---|---|
Definition | A fistula is a disease due to the formation of a passageway inside an infected gland of the anus. | A pilonidal sinus is a disease due to the formation of a cyst-like structure that develops along the tailbone, just near the cleft of the buttocks. |
Prevalence | Fistulas are not specific to any age group or gender. | Pilonidal sinuses are more common in young adults and young men are more prone to developing them. |
Symptoms | Both conditions involve abscesses in the region and can cause drainage and pain. | Both conditions involve abscesses in the region and can cause drainage and pain. |
Cause | Fistulas are typically caused by an infection in a gland, leading to the formation of an abnormal passageway. | Pilonidal sinuses are caused by a cyst-like structure that develops along the tailbone and can become infected. |
Treatment | Treatment for fistulas usually involves surgery to remove the infected gland and the passageway. | Treatment for pilonidal sinuses may involve lancing the abscess, draining the infected material, and sometimes surgery to remove the sinus. |
Please note that in very rare and severe cases, a pilonidal sinus can cause a fistula, known as pilonidal fistula-in-ano. However, this condition is extremely rare, with only six reported cases.
