Perianal Abscess

What is a perianal abscess?

A perianal abscess also called anorectal abscess is a collection of pus in the tissue around the anus and rectum. It arises from an anal infection or blocked glands which leads to inflammation and abscess formation. This abscess causes extreme pain and discomfort for patients.

“If left untreated, a perianal abscess will develop a serious complication called a fistula” – says fistula treatment experts at Kalp Hospital. Anal fistula or fistula is a tunnel that makes an abnormal connection between the site of the abscess and the skin. In some cases, anal fistulas may cause persistent drainage that results in recurrent anal abscesses. This condition often requires more intensive surgery.

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 abscess is diagnosed?

Most anorectal or perirectal abscesses are usually diagnosed based on your medical history and a physical exam. If an abscess is located within the anal canal, your doctor may perform an endoscopy to look inside the anal canal and lower rectum.

Sometimes imaging tests such as computed tomography (CT) scan or magnetic resonance imaging (MRI) may be used especially if the abscess is deeper. During the physical exam, your doctor will want to make sure of whether the mass is an abscess or hemorrhoids.

Further tests may be recommended to ascertain that IBD or Crohn’s disease is not a contributing factor. In these cases, blood tests and colonoscopy, using a lighted and flexible scope to examine colon are required.

How perianal or perirectal abscess is treated?

Surgery is the standard treatment for anorectal abscess – says Dr. Naresh, the best colorectal surgeon.

Anorectal abscess rarely goes on their own with antibiotic therapy. Because these abscesses are an indication of timely incision and drainage. In most cases, incision and drainage are performed typically in an office setting that involves a local anesthetic.

However, if the anal abscess is large and deeper or situated high in the rectum, the procedure may require hospitalization and general anesthesiologist. This procedure generally takes around 30 mins. After the procedure, antibiotics are prescribed to help treat the infection and pain relief. Patients may also be advised to use a sitz bath, to soak and clean the anal area.

During recovery, stool softeners and medications may be needed to allow the drained abscess to heal better. After every bowel movement, wiping the area gently with toilet paper and rinsing with warm water helps decrease the patient’s discomfort.

When to see a doctor?

Once the perianal abscess surgery is done, the drainage of the abscess will provide almost immediate relief. Sometimes, pain and discomfort are usually mild and can be controlled by pain medications. However, if you experience excessive rectal bleeding, fever, chills, or vomiting after the abscess surgery consult the doctor immediately.
