Removal of anal seton, other marker
CPT4 code
Name of the Procedure:
Removal of Anal Seton Other terms: Seton removal, Anal seton extraction
Summary
In layman's terms, the removal of an anal seton involves taking out a special suture (seton) that has been previously placed in the anal area to help with certain medical conditions.
Purpose
This procedure addresses conditions like anal fistulas or abscesses. The goal is to remove the seton once it has served its purpose, which is usually to keep a fistulous tract open to promote drainage and healing, or to prepare the area for further treatment.
Indications
- Presence of an anal fistula
- Resolving anal abscess
- The seton has fulfilled its purpose and needs to be removed for further healing
Preparation
- Patients may be asked to fast for a few hours prior to the procedure.
- A thorough medical history and physical examination will be conducted.
- Any medications should be discussed with the healthcare provider, particularly blood thinners.
Procedure Description
- Anesthesia: Local anesthesia is commonly used, though sedation may be necessary for patient comfort.
- Positioning: The patient is typically positioned in a way that allows easy access to the anal area, often lying on their side.
- Removal: The healthcare provider will carefully cut and remove the seton using surgical scissors or a scalpel. The area is inspected to ensure proper healing.
- Aftercare: The area may be cleaned, and a dressing may be applied if necessary.
Tools Used:
- Surgical scissors or scalpel
- Local anesthetic
- Gauze and antiseptics
Duration
The procedure typically takes about 15 to 30 minutes.
