Perianal abscess

Perianal abscess is a type of abscess that develops near the anus. Most commonly caused by the infection of an anal gland, a perianal abscess can cause severe pain and discomfort.

Causes

The primary cause of a perianal abscess is the infection of an anal gland. These glands are small pockets located inside the anus, which can become blocked and subsequently infected. Other causes can include sexually transmitted infections, Crohn's disease, and diabetes.

Symptoms

The symptoms of a perianal abscess can vary, but often include severe pain in the anal area, a visible lump near the anus, and sometimes fever or general malaise. If the abscess ruptures, pus may be visible.

Diagnosis

Diagnosis of a perianal abscess is typically made through a physical examination. In some cases, a doctor may order additional tests such as an ultrasound, MRI, or CT scan to confirm the diagnosis and assess the extent of the infection.

Treatment

Treatment for a perianal abscess usually involves surgical drainage of the abscess to relieve symptoms and prevent further infection. This is often done under local anesthesia. In some cases, antibiotics may also be prescribed.

Prognosis

With prompt treatment, the prognosis for a perianal abscess is generally good. However, if left untreated, the infection can spread and lead to serious complications such as fistula formation or systemic infection.
