An anal fistula can cause repeated pain, swelling, pus discharge, bleeding, and abscess formation near the anus. Many patients delay treatment because they are worried about conventional open surgery, painful dressings, a long recovery period, or damage to the muscles responsible for bowel control.
For selected patients, fistula treatment without open surgery in Gurgaon may be possible using minimally invasive or sphincter-preserving procedures such as laser fistula closure, VAAFT, LIFT, or seton-based treatment.
However, “without open surgery” does not mean completely non-surgical, incision-free, or guaranteed painless. Most fistulas require a procedure to close, drain, or remove the infected tract. The objective of minimally invasive treatment is to avoid laying the entire fistula tract open when doing so could produce a large wound or damage the anal sphincter muscles.
Sarthi Care provides specialist evaluation and coordinates conventional and minimally invasive fistula-treatment options in Gurgaon.
What Is an Anal Fistula?
An anal fistula is an abnormal tunnel connecting the anal canal to the skin near the anus. It most commonly develops after an anal abscess or infected anal gland fails to heal completely.
The abscess may drain naturally or after treatment, but an infected tract can remain beneath the skin. This tract can repeatedly collect pus, discharge fluid, and cause another abscess.
Common symptoms include:
- A small opening near the anus
- Repeated pus or fluid discharge
- Pain around the anal opening
- Swelling that improves after discharge
- Blood mixed with the discharge
- Skin irritation or itching
- A foul smell from the affected area
- Recurrent boils or abscesses
- Fever during an active infection
- Pain while sitting or passing stool
An anal fistula rarely heals permanently with medicines alone. Treatment commonly involves surgery, although the type of surgery depends on the fistula’s location, shape, and relationship with the anal sphincter muscles.
What Does “Without Open Surgery” Actually Mean?
Traditional fistulotomy treats a fistula by cutting open the complete tract so that it can heal from its base. This can be an effective option for a simple, low fistula involving little sphincter muscle.
The problem arises when a fistula passes through a substantial portion of the sphincter. Opening the entire tract could divide too much muscle and increase the risk of difficulty controlling gas or stool.
Minimally invasive treatment attempts to close or treat the fistula internally while preserving as much sphincter muscle as possible. These procedures may create smaller wounds than conventional fistulotomy, but they are still operations performed under anesthesia.
Patients should therefore be cautious of advertisements claiming the following:
- Completely non-surgical fistula treatment
- Guaranteed treatment without any cut
- Permanent cure in one sitting
- Zero recurrence
- Completely painless surgery
- Laser treatment suitable for every fistula
No responsible surgeon can make these promises before examining and mapping the fistula.
Minimally Invasive Fistula-Treatment Options
Laser fistula treatment or FiLaC
FiLaC stands for fistula-tract laser closure. A thin laser fiber is introduced into the fistula tract. Controlled laser energy is delivered as the fiber is gradually withdrawn, aiming to destroy the tract lining and cause it to shrink and close.
The laser is applied from inside the tract rather than opening its full length. This can help protect the sphincter muscles and reduce the size of the external wound.
Laser treatment may be performed under regional or general anesthesia. It can also be combined with another technique to close the fistula’s internal opening.
Laser treatment is not guaranteed to cure every fistula. NICE states that there are no major safety concerns, but the evidence regarding the procedure’s effectiveness remains limited in quality and quantity. Patients should be clearly informed about this uncertainty before treatment.
VAAFT
VAAFT means video-assisted anal fistula treatment. During this procedure, the surgeon passes a narrow fistuloscope containing a camera into the fistula.
The camera allows the surgeon to inspect the tract from inside, identify branches, and locate the internal opening. The tract is then cleaned and treated using instruments passed through the fistuloscope.
VAAFT avoids opening the entire fistula externally. Its suitability depends on whether the tract can be entered and visualized properly. A very narrow, blocked, or severely scarred tract may not be appropriate for this approach.
LIFT procedure
LIFT stands for ligation of the intersphincteric fistula tract. It is often considered for fistulas that cross the anal sphincter muscles and would make a full fistulotomy risky.
The surgeon accesses the fistula through the space between the internal and external sphincter muscles. The tract is identified, divided, and sealed.
LIFT is described as a sphincter-preserving procedure, but it is not incision-free. A small surgical cut is required to reach the tract. It should therefore be described as an alternative to laying open the complete fistula rather than “surgery without cuts.”
Seton treatment
A seton is a surgical thread or similar material passed through the fistula tract. A loose seton maintains drainage and helps control repeated infection without dividing the sphincter muscle.
A draining seton may be used as the first stage of treatment for a complex or infected fistula. After the infection settles, the patient may undergo laser closure, LIFT, an advancement flap, or another definitive procedure.
A loose seton generally controls drainage but does not necessarily cure the fistula by itself. Some patients require more than one operation.
Advancement-flap procedure
An advancement flap may be recommended when the fistula passes through the sphincter and opening the tract would create a high risk of incontinence.
The internal opening is covered using healthy tissue taken from inside the rectum. Although this procedure avoids cutting through a large amount of sphincter muscle, it is still a surgical operation and may involve a larger intervention than laser treatment.
Fibrin glue
Fibrin glue is injected into the fistula to seal the tract. The NHS describes this as a non-surgical option, although it is usually administered under anesthesia.
Its main limitation is effectiveness. Results may not last, and it is generally less effective than fistulotomy for simple fistulas. It may be considered when avoiding sphincter division is particularly important.
Who May Be Suitable for Treatment Without Open Fistulotomy?
Minimally invasive or sphincter-preserving treatment may be considered for patients with:
- A fistula passing through the anal sphincter
- A recurrent fistula after previous surgery
- A complex or branching tract
- More than one external opening
- A high transsphincteric fistula
- A horseshoe-shaped fistula
- Existing concerns about bowel control
- A fistula where conventional opening could create a large wound
- A preference for a smaller wound when clinically appropriate
The final decision depends on the fistula anatomy, not simply the patient’s preference for laser surgery.
Clinical guidance defines complex fistulas as those involving a significant portion of the external sphincter, high or branching tracts, horseshoe fistulas, and fistulas associated with conditions such as inflammatory bowel disease, radiation injury, or existing incontinence.
Is MRI Required Before Minimally Invasive Treatment?
MRI is not compulsory for every straightforward fistula. A simple, superficial tract may sometimes be identified through examination and assessment under anesthesia.
An MRI fistulogram may be recommended when the fistula is
- Recurrent
- High or complex
- Branching in different directions
- Associated with repeated abscesses
- Difficult to define during examination
- Previously operated on
- Suspected to have hidden extensions
MRI can help the surgeon locate the internal opening, identify secondary branches, and understand how much sphincter muscle is involved.
Skipping imaging in a complex case merely to reduce the initial cost can be a false economy. An unidentified secondary tract can contribute to continued discharge, abscess formation, or recurrence.
Benefits of Minimally Invasive Fistula Treatment
Potential advantages for appropriately selected patients include:
- Avoidance of a large open wound
- Better preservation of the anal sphincter
- Less cutting of healthy tissue
- Reduced postoperative wound care
- Less discomfort in some patients
- Daycare treatment in suitable cases
- Earlier return to light activities
- Lower risk of continence damage than inappropriate sphincter division
These are potential benefits, not guaranteed results. The most important outcome is successful fistula healing without damaging bowel-control muscles.
Clinical guidelines report that laser and endoscopic techniques can produce reasonable short-term healing, but their long-term healing and recurrence outcomes remain uncertain.
What Happens on the Day of Treatment?
The patient is admitted to the hospital or surgical center according to the scheduled time. The surgeon reviews the planned procedure, and the anesthesia team checks the patient’s medical fitness.
The treatment may involve:
- Examination under anaesthesia
- Identification of the internal and external fistula openings
- Cleaning and probing of the tract
- Laser closure, VAAFT, LIFT, seton placement or a combined procedure
- Treatment or drainage of any abscess
- Closure of the internal opening when required
- Postoperative observation
Many patients can leave the hospital on the day of surgery. A complex or branching fistula may require overnight observation. The discharge decision depends on the operation, pain control, bleeding, recovery from anesthesia, and the patient’s general condition.
Recovery After Minimally Invasive Fistula Treatment
Recovery varies according to the procedure and fistula complexity. A smaller external wound does not mean that the internal tract heals immediately.
Patients may experience:
- Mild or moderate pain
- Fluid or blood-stained discharge
- Temporary swelling
- Discomfort while passing stool
- The need for pads or dressings
- Fatigue after anaesthesia
Post-treatment instructions may include:
- Take prescribed medicines correctly.
- Use stool softeners when advised.
- Drink sufficient water.
- Eat fiber-rich food.
- Avoid straining during bowel movements.
- Take warm sitz baths.
- Keep the area clean and dry.
- Change dressings as instructed.
- Avoid heavy lifting.
- Attend every follow-up appointment.
Contact the treating team for fever, worsening pain, heavy bleeding, increasing swelling, inability to pass urine, persistent vomiting, or loss of bowel control.
Can a Complex Fistula Be Treated Without Open Surgery?
Some complex fistulas can be treated using sphincter-preserving techniques, but one procedure may not be enough.
The surgeon may first insert a draining seton to control infection. Laser treatment, LIFT, or another closure procedure may then be performed after the inflammation has settled.
In other cases, a combined operation provides a better chance of healing than laser alone. The correct treatment must balance two competing goals:
- Closing every important part of the fistula
- Protecting the muscles responsible for continence
Choosing laser simply because it sounds modern is poor decision-making if the tract anatomy makes another procedure more appropriate.

Frequently Asked Questions
Is fistula treatment possible without open surgery?
Yes, selected fistulas can be treated without opening the entire tract. Options may include laser closure, VAAFT, LIFT, a seton, or an advancement flap.
Is laser fistula treatment non-surgical?
No. Laser treatment is a minimally invasive surgical procedure performed under anesthesia. It treats the tract internally but is not a medicine-only treatment.
Is laser suitable for every fistula?
No. Suitability depends on the tract’s length, branches, internal opening, active infection, sphincter involvement, and previous operations.
Can fistula treatment be completed in one day?
Many procedures are performed as daycare surgery. Complex fistulas may require overnight observation or staged treatment over more than one procedure.
Is minimally invasive fistula surgery painless?
Anesthesia prevents pain during treatment. Some postoperative pain, pressure, or discharge can still occur.
Can an anal fistula return after laser treatment?
Yes. Recurrence is possible after laser and other fistula procedures. No technique can honestly guarantee permanent closure in every case.
