What is an Anorectal Abscess?
An anorectal abscess is a collection of pus in the tissue surrounding the anus and rectum. It is caused by bacterial infection of small glands inside the anus. If untreated promptly, the infection can spread and lead to a fistula or systemic infection.
Types of Anorectal Abscesses
- Perianal abscess – Most common, just under the skin around the anus
- Ischiorectal abscess – Located in the space beside the rectum
- Intersphincteric abscess – Between the internal and external sphincter muscles
- Supralevator abscess – Above the levator ani muscle; rare and complex
- Horseshoe abscess – Extends around both sides of the anus
Symptoms
- Severe, constant throbbing pain around the anus
- Swelling, redness, and warmth near the anal area
- Discharge of pus or blood
- Fever and chills (indicating spread of infection)
- Difficulty sitting or walking
- Painful bowel movements
Our Treatment Approach
- Emergency incision and drainage – Immediate relief by releasing pus under local anaesthesia
- Wound packing and irrigation – Ensures complete drainage and prevents reformation
- Antibiotics – Used selectively when infection has spread beyond the abscess
- Fistula management – If a fistula has formed, we offer simultaneous or staged treatment
- Follow-up wound care – To monitor healing and prevent recurrence
- Elective procedures – For recurrent abscesses, the underlying gland may need treatment
When to Seek Immediate Help
- Severe anal pain that is rapidly worsening
- High fever accompanying anal swelling
- Inability to sit or walk comfortably
- Any sign of spreading redness around the anus
- If a previous abscess has recurred
