What Is a Perianal Abscess?
A perianal abscess is a collection of pus that forms in the tissues around the anus. It develops when the small glands lining the anal canal become blocked and infected, leading to pain, swelling, and potential spread of infection if not treated promptly.
Common Causes and Risk Factors
Blocked or infected anal glands
Inflammatory bowel diseases such as Crohn's disease
Diabetes or any condition that weakens the immune system
Poor hygiene or repeated skin irritation
Smoking, obesity, or other factors that impair circulation
Signs and Symptoms
Sharp or throbbing pain near the anus
Redness, swelling, or a firm lump around the anal opening
Discomfort when sitting, walking, or during bowel movements
Fever, chills, or general malaise if the infection is severe
Drainage of pus or blood from the abscess site
How Dr. Nghia Nguyen Diagnoses a Perianal Abscess
Dr. Nguyen starts with a full review of your symptoms and health history. He performs a physical exam to check the area for swelling, tenderness, or discharge.
If the abscess is deep or unclear, he may use imaging tests like ultrasound or MRI to find the size and location.
For insurance purposes, the ICD-10 code for a perianal abscess is K61.0.

Frequently Asked Questions
How long does recovery take without surgery?
Smaller abscesses may heal with antibiotics and sitz baths in one to two weeks if no drainage is required.
Can I avoid surgery for a perianal abscess?
If caught early, some abscesses respond to medication and warm baths alone. Dr. Nguyen will advise if incision and drainage are needed.
How likely is it to return?
Up to one in three people may experience a recurrent abscess. Maintaining good hygiene and diet reduces the chance of recurrence.
How can I prevent another abscess?
Eat a high-fiber diet, stay well hydrated, practice proper anal hygiene, and address any irritation or infection early.
Is drainage painful?
Dr. Nguyen uses a local anesthetic to numb the area. Most patients feel only slight pressure, not pain, during the procedure.
Will my insurance cover the treatment?
Yes. We use ICD-10 code K61.0 for billing, and our staff can help verify your coverage before treatment.
When should I see a specialist?
Call our office if you have severe pain, swelling, fever, or pus. Early evaluation prevents complications and promotes faster relief.
