LIFT technique

Surgical technique for treating anal fistulas

The LIFT technique (Ligation of Intersphincteric Fistula Tract) is a surgical procedure used to treat anal fistulas. This technique is designed to close the fistula tract and preserve the anal sphincter muscles, thereby minimizing the risk of fecal incontinence.

Procedure

The LIFT technique involves several key steps, which are performed under anesthesia. The procedure is typically done on an outpatient basis.

Identification of the Fistula Tract

The first step in the LIFT procedure is to identify the fistula tract. This is done by probing the external opening of the fistula to locate the tract.

Identifying the internal opening of the fistula

Incision at the Intersphincteric Groove

Once the tract is identified, an incision is made at the intersphincteric groove. This allows access to the fistula tract between the internal and external sphincter muscles.

Dissection and Ligation of the Tract

The fistula tract is then carefully dissected and isolated. The tract is ligated at the level of the intersphincteric space to prevent the passage of fecal material through the tract.

Suturing the Tract

After ligation, the tract is sutured to ensure it is securely closed. This step is crucial to prevent recurrence of the fistula.

Curettage of the External Opening

The external opening of the fistula is curetted to remove any granulation tissue and to promote healing.

Closure of the External Sphincter

Finally, the external sphincter is closed, completing the procedure.

Advantages

The LIFT technique offers several advantages over traditional fistula surgery methods:

• Sphincter Preservation: By avoiding division of the sphincter muscles, the risk of incontinence is significantly reduced.
• High Success Rate: The procedure has a high success rate in terms of fistula healing and low recurrence rates.
• Minimal Postoperative Pain: Patients typically experience less pain compared to other surgical techniques.

Complications

While the LIFT technique is generally safe, potential complications include:

• Infection
• Recurrence of the fistula
• Bleeding
• Temporary incontinence
