Perianal Abscess

Understanding Perianal Abscess & Its Risks

At Star Surat Piles & Colorectal Clinic, we often treat patients experiencing extreme pain and swelling due to perianal abscess—a condition also known as anorectal abscess. It occurs when an infection or blocked gland near the anus causes a buildup of pus, leading to inflammation and severe discomfort.

Our fistula treatment experts warn,

“If left untreated, a perianal abscess will develop a serious complication called a fistula” – Fistula treatment experts at Star Surat Piles & Colorectal Clinic

An anal fistula is an abnormal tunnel that connects the original abscess site to the skin. It can cause ongoing drainage and may result in repeated abscess formation. Treating fistulas often requires advanced surgical intervention.

We specialize in the comprehensive treatment of perianal abscess and fistula, offering minimally invasive and effective solutions for long-term relief.

What are the Causes of Perianal Abscess?

A perianal abscess can have many different causes that include blocked gland, sexually transmitted infections, and an untreated anal fistula. Some other risk factors for anal abscess include:

inflammatory bowel diseases such as chron’s disease or ulcerative colitis.

Diabetes

Diverticulitis

Pelvic inflammatory disease

Having anal sex

Use of medications that suppress the body’s immune system such as prednisone.

Undergoing chemotherapy for cancer

What are the Symptoms of Perianal Abscess?

Throbbing and constant pain when sitting down is probably one of the most common symptoms of a perianal or perirectal abscess. This pain is accompanied by swelling in the anal area or buttocks and severe pain during bowel movements.

Other symptoms of an anal abscess include:

Discharge of pus or bleeding near the anus.

Fever and chills

Fatigue

Constipation

A lump in the anal area

Tenderness or itching of the skin around the anus.

How Perianal or Perirectal Abscess is treated?

At Star Piles Surat, we emphasize early diagnosis and treatment of constipation to prevent serious complications. While occasional constipation is usually harmless, chronic constipation—when left untreated—can lead to several distressing conditions that may require medical or surgical intervention.

Medical Management

While antibiotics may be prescribed to manage infection and provide temporary relief, anorectal abscesses rarely resolve on their own with medication alone. Antibiotic therapy is usually considered supportive and not a definitive treatment.

Surgical Intervention (Standard Treatment)

Surgery is the primary and most effective treatment for perianal or perirectal abscesses.

Incision and drainage (I&D) is the most common procedure. It’s often performed in a clinical setting under local anesthesia.
For larger, deeper, or high rectal abscesses, hospitalization and general anesthesia may be required.
After the procedure:
- Antibiotics are prescribed to treat any remaining infection.
- Pain relief medication is given for comfort.
- Sitz baths are advised to promote hygiene and healing.
- Stool softeners may be used to prevent strain and support smooth recovery.
- Gentle cleaning with warm water after each bowel movement helps reduce discomfort.

Early intervention and proper care are key to preventing complications such as anal fistulas.

Possible Complications

In some cases, especially when the abscess is large or when a fistula with abscess is present, a patient may require staged surgery.

This approach is taken to fully eliminate infection, ensure complete healing, and reduce the risk of recurrence.

Staged Surgery May Be Needed If:

The abscess is deep or extensive

A complex anal fistula is also involved

There’s ongoing infection or drainage despite initial treatment

Staged surgery involves performing drainage first and planning a second procedure (like fistula repair) after the infection has settled.
