Fistula disease can be treated through surgery, with several methods available. The LIFT technique is a highly effective approach for treating anal fistulas. This technique closes the connection between the anal canal and the skin without damaging the sphincter muscles, unlike other surgical methods that may require cutting the anal sphincter muscle, which can affect bowel control.

Normally, the body has two circular sphincter muscles around the anus, similar in shape to a donut. During LIFT surgery, the doctor makes an incision between the inner and outer sphincter muscles to separate the fistula tract. The surgeon then opens and scrapes the fistula tract to destroy it, followed by closing the separated fistula in the muscle layer without cutting the sphincter. This prevents stool from accumulating and causing further infections.

• Preservation of sphincter muscles: There is no impact on bowel control.
• Minimal scarring and pain
• No dressing changes required
• Hospital stay of just one night
• Over 80% chance of complete recovery
• Improved quality of life

LIFT surgery is a minor procedure, so the risks are low. However, potential risks include:

• Infection
• Recurrence of the fistula

Patients can recover at home for about 4–5 days without needing wound care. Normal bowel movements can resume, and light activities are allowed. It’s essential to follow up with the doctor as scheduled. About three months post-surgery, the doctor will evaluate whether the fistula is fully healed.

Doctors will select the most suitable technique for each patient. The LIFT technique, pioneered by teams at Chulalongkorn and Bumrungrad hospitals, provides a high level of expertise and experience in successfully performing this procedure and minimizing recurrence rates.
