Name of the Procedure:

Incision and drainage of ischiorectal or intramural abscess, with fistulectomy or fistulotomy, submuscular, with or without placement of seton.

Summary

This procedure involves making an incision to drain an abscess located in the ischiorectal or intramural region. It often includes removing or opening an abnormal passage (fistula) that may extend from the intestine to the skin. Sometimes, a seton (a piece of surgical thread) is placed to help the area heal.

Purpose

The procedure addresses abscesses and fistulas in the anorectal region, which can cause pain, swelling, infection, and drainage issues. The goal is to eliminate the infection, reduce discomfort, and promote proper healing of the affected area.

Indications

• Persistent pain and swelling in the anorectal region.
• Discharge of pus or blood from an opening near the anus.
• Diagnosis of an anorectal abscess or fistula via clinical assessment or imaging.
• Failure of conservative treatments such as antibiotics or sitz baths to resolve the issue.

Preparation

• Fasting for at least 6 hours before the procedure.
• Ceasing certain medications as advised by your doctor.
• Undergoing a pre-operative assessment including blood tests and possibly imaging studies like an MRI or ultrasound for precise diagnosis.

Procedure Description

1. The patient is positioned to provide optimal access to the anorectal area.
2. Anesthesia is administered, typically general or regional.
3. The surgeon makes an incision to drain the abscess.
4. If a fistula is present, a fistulectomy (removal of the fistula) or fistulotomy (opening the fistula) is performed.
5. A seton may be placed to ensure continuous drainage and facilitate healing.
6. The area is cleaned, and dressings are applied.

Duration

The procedure usually takes between 30 minutes to 1 hour, depending on complexity.

Setting

This procedure is performed in a hospital operating room or an outpatient surgical center.

Personnel

• Surgeon (usually a colorectal or general surgeon)
• Anesthesiologist
• Nursing staff

Risks and Complications

• Infection
• Bleeding
• Recurrence of abscess or fistula
• Incontinence (rare)
• Pain and discomfort post-procedure
• Reactions to anesthesia

Benefits

• Relief from pain and swelling.
• Elimination of infection.
• Prevention of further complications and recurrence.
• Improvement in quality of life.

Recovery

• Pain management with prescribed medications.
• Instructions on wound care and hygiene.
• Avoiding strenuous activities for a few weeks.
• Follow-up appointments for monitoring recovery.
• Complete recovery often takes 2-6 weeks, depending on individual circumstances.

Alternatives

• Conservative treatment with antibiotics and sitz baths.
• Needle aspiration (less invasive, higher recurrence risk).
• Endoscopic procedures (feasibility depends on fistula location).
• Each alternative has its own benefits and drawbacks and may be more suitable depending on the specific case.

Patient Experience
