SURGICAL EMERGENCY
Perianal Abscess
A painful collection of pus near the anus caused by a blocked and infected anal gland. Perianal abscess treatment means same-day surgical drainage, do not delay.
ABOUT THIS CONDITION
What is Perianal Abscess?
A perianal abscess is an acute infection forming a pocket of pus near the anus. It typically arises from a blocked anal gland that becomes infected, a process known as cryptoglandular infection. The condition produces severe, throbbing pain and swelling, and is considered a surgical emergency. Prompt drainage prevents the infection from spreading and significantly reduces the 30-40% risk of fistula formation. Anal abscess treatment is available on a same-day emergency basis. Dr. Samhitha Reddy, a specialist for perianal abscess surgery, ensures thorough drainage, appropriate wound management, and close post-procedure surveillance for fistula development.

WHY IT HAPPENS
Causes & Risk Factors
- Blocked or infected anal gland, cryptoglandular origin (most common)
- Crohn's disease affecting the perianal region
- Sexually transmitted infections causing anal gland infection
- Trauma or injury to the anal region
- Diabetes mellitus, increased susceptibility to infection
- Immunosuppression, including HIV, chemotherapy, or steroid use
CLINICAL DETAILS
KeyFacts
Same-day or next-day surgical drainage is essential, do not wait
30-40% of inadequately treated perianal abscesses develop fistulas
Examination under anaesthesia allows full assessment and complete drainage
Antibiotics alone cannot treat an established abscess, drainage is mandatory
Most patients are significantly more comfortable within 24 hours of drainage
Close surveillance for 4-12 weeks post-drainage to detect any fistula formation
HOW WE TREAT IT
Treatment Approach
Urgent Drainage + Fistula Prevention
Prompt, complete drainage of a perianal abscess is the single most important step in preventing fistula formation. Dr. Samhitha provides same-day anal abscess surgery, incision and drainage (I&D) or EUA with drainage under appropriate anaesthesia, ensuring thorough evacuation of the abscess cavity. Post-procedure, close follow-up monitors for fistula development.
- 1
Emergency Assessment
Dr. Samhitha performs an urgent clinical examination to confirm the diagnosis, assess extent of the abscess, and determine whether local or general anaesthesia is needed for optimal drainage.
- 2
Incision and Drainage (I&D)
A carefully placed incision drains the pus completely. The wound is packed to allow healing from inside out. This is the essential, definitive treatment, antibiotics alone are ineffective.
- 3
EUA + Drainage
Examination under anaesthesia (EUA) is used when the abscess is deep, complex, or when full clinical assessment is not possible without anaesthesia. Allows complete drainage and early identification of any fistula tract.
- 4
Post-Procedure Care & Fistula Surveillance
Daily wound dressings and warm sitz baths promote healing. Dr. Samhitha monitors for fistula formation over 4-12 weeks post-drainage, the most common complication of perianal abscess.
