Second-opinion centre for already-operated fistula
A complex anal fistula is one that involves a large part of the anal sphincter, has multiple or horseshoe tracts, sits high in the anal canal, or has already recurred after previous surgery. At Sharvari Hospital, Pimple Nilakh, Pune, these cases are planned on MRI fistulography and treated with sphincter-preserving techniques — draining seton, LIFT, laser (FiLaC), VAAFT or advancement flap — often in stages, to close the tract while protecting bowel control. The full programme — every technique, the cost table and the FAQs — is on our fistula treatment in Pune page.

You are not an unusual case, and it is not your fault.
Anal fistula recurs more often than most patients are told before their first surgery. Published surgical series put recurrence after fistula surgery anywhere between roughly 7% and 30%, and it climbs with each additional complexity factor — a high tract, more than one tract, a horseshoe extension, an anterior fistula in a woman, or underlying disease that was never looked for.
What changes the outcome the second time is not a newer laser. It is a correct map of the tract before the operation and a plan that matches the anatomy rather than the marketing.
At Sharvari Hospital, every re-operated fistula starts from zero: fresh MRI, fresh examination under anaesthesia, and an honest answer about what is actually achievable — including how many stages it may take.
Bring your old MRI and discharge summary. We will read them with you.
Surgeons classify fistula tracts using the Parks classification — intersphincteric, transsphincteric, suprasphincteric and extrasphincteric — based on how the tract runs relative to the anal sphincter muscles. A fistula is generally called complex when one or more of the following is present:
| Feature | Why it matters |
|---|---|
| High transsphincteric tract (crossing a large share of the external sphincter) | Simply laying it open risks bowel-control problems |
| Suprasphincteric or extrasphincteric tract | Runs above or outside the sphincter complex — never suitable for fistulotomy |
| Multiple tracts or a horseshoe extension | One opening treated, others left behind → recurrence |
| Recurrent fistula after previous surgery | Scarring distorts the anatomy and hides the original internal opening |
| Anterior fistula in a woman | Thin sphincter in front; higher continence risk |
| Existing incontinence or previous sphincter injury | Very little muscle reserve to spend |
| Underlying Crohn's disease, tuberculosis or malignancy | The tract will not heal until the disease is treated |
| Previous pelvic radiation | Impaired tissue healing |
A simple, low fistula can often be laid open in one sitting. A complex fistula cannot — and attempting it anyway is one of the commonest reasons patients arrive here with both a persistent fistula and a control problem.
Read the basics first → Types of anal fistula: simple vs complex · What is anal fistula?
The internal opening was never found. If the source in the anal canal is missed, the tract refills. This is the single most common cause of recurrence.
A secondary tract or horseshoe extension was left behind. The main tract healed; the branch did not.
The tract had epithelialised — lined itself with skin-like tissue that will not stick together and close.
The wound closed at the skin before it healed in the depth, trapping infection and rebuilding the tract from inside out.
Inadequate drainage of an associated abscess before the definitive procedure.
Underlying disease was never excluded — Crohn's disease, and in India, tubercular fistula-in-ano, which is genuinely under-diagnosed. No surgical technique cures a tubercular tract without medical treatment alongside.
The technique did not match the anatomy — a sphincter-preserving procedure chosen for the wrong tract, or a laser used where a flap was needed.
Every one of these seven is identifiable before the second operation. That is the entire point of a proper re-assessment.
What causes recurrent fistula · Fistula surgery success rate — what the data says
For any complex or recurrent fistula, MRI of the pelvis with fistula protocol is the reference-standard investigation. It shows the primary tract, secondary tracts, horseshoe extensions, undrained collections and — critically — the relationship of the tract to the sphincter muscles. We do not plan redo fistula surgery without it.
Four findings on the scan change the operation: how much sphincter muscle the tract crosses, whether there is an abscess that must be drained first, whether a secondary tract or horseshoe extension is present, and whether the tract climbs above the pelvic floor. The report's grade is a radiology shorthand — the plan is built from those findings and confirmed under anaesthesia. What each line of the report means is explained on our MRI fistula mapping page, and a fully mapped, probe-confirmed case is written up as a de-identified case study.
A man in his early thirties, operated for a fistula elsewhere about eight years earlier, came with eight days of pain, one small opening near the anus and no significant discharge. His MRI fistulogram showed a 6 cm horseshoe abscess in the posterior perirectal and intersphincteric space, a probable internal opening at 6 o’clock and a 6.5 cm tract crossing the right external sphincter — St James’s grade IV, with nothing on the surface to suggest any of it. Because the scan was done first, the abscess and internal opening were laid open and drained from inside, the part of the tract crossing the muscle was cored out rather than cut, and the tract was removed to the skin — with the external sphincter left intact. The full, de-identified write-up is the recurrent complex fistula case study.
The old operative note tells us what was found, what was divided and what was left. Bring it. If you do not have it, we will help you request it.
The definitive assessment. Scarring from previous surgery can hide the internal opening on clinic examination; under anaesthesia, with probes and dye, it can usually be identified.
Where the history suggests it — multiple recurrences, unusual tract behaviour, systemic symptoms — we investigate for Crohn's disease and tuberculosis before committing to a definitive procedure. Treating the disease is part of curing the fistula. How TB and Crohn's fistulas are diagnosed and treated.
If you already have any degree of urgency, soiling or reduced control, that changes the surgical plan entirely. We ask, we document it, and we protect what is left.
How is anal fistula diagnosed? MRI, ultrasound and tests explained
There is no single best operation for a complex fistula. There is a best operation for your tract.
| Procedure | Best suited to | Sphincter risk | Typical recovery | Notes |
|---|---|---|---|---|
| Draining seton | Almost every complex/recurrent case, as stage one | Very low | Return to work in days; seton stays weeks–months | Not a cure — it controls infection and lets the tract settle so the definitive procedure can work |
| LIFT (Ligation of Intersphincteric Fistula Tract) | Transsphincteric tracts with a well-formed tract | Low | 2–4 weeks | Published series report healing broadly in the 60–75% range |
| FiLaC / laser closure | Suitable tracts, including some recurrent cases | Low | Often daycare; 2–4 weeks | Sphincter-sparing; repeatable if it fails |
| VAAFT (video-assisted) | Complex and multi-tract fistulas — the scope sees the branches | Low | 2–4 weeks | Particularly useful where secondary tracts are suspected |
| Endorectal / anodermal advancement flap | High tracts, recurrent cases, anterior fistula in women | Low–moderate | 4–6 weeks | Healthy tissue is brought down to close the internal opening |
| Fistulotomy | Only genuinely low, simple tracts | High if misapplied | 3–6 weeks | Highest cure rate, but not appropriate for high or complex tracts |
| Staged / combination approach | Multiple failures, horseshoe tracts, heavy scarring | Low | Months, in planned steps | Often the honest answer for a third or fourth operation |
How we choose: tract level on MRI → sphincter involvement → number of tracts → your existing continence → what has already been tried and failed. In heavily re-operated cases we will usually recommend a staged plan and say so up front, rather than promise a single-sitting cure.
We will not offer you a guarantee. Anyone who guarantees a cure for a recurrent complex fistula is telling you what you want to hear.

The fear behind every recurrent-fistula consultation is rarely spoken aloud: will I lose control of motion?
The honest position:
In complex and recurrent anal fistula, the surgical priority shifts from fastest cure to sphincter preservation, because continence lost cannot be surgically restored as reliably as a fistula can be re-treated.

| Consultation + assessment | As per current schedule |
| MRI fistulography | As per current radiology schedule |
| Complex / recurrent fistula surgery | ₹85,000 onwards |
| Staged procedures | Quoted per stage before you commit |
Final cost depends on the number of tracts, whether the procedure is staged, anaesthesia and stay. You get a written estimate before admission. Cashless treatment is available with 50+ insurers.

Yes, in most cases. Recurrence usually means the tract was incompletely mapped or an underlying cause was missed, not that the fistula is incurable. The starting point is a fresh MRI fistulography and an examination under anaesthesia, not another immediate operation.
No. Multiply-operated fistulas are treatable, but the plan changes: treatment is usually staged, with a draining seton placed first, and the priority shifts to protecting remaining sphincter function over achieving a single-sitting cure.
Yes. Recurrence after several operations usually means a missed internal opening or secondary tract. MRI fistulogram, examination under anaesthesia and a staged sphincter-preserving repair are how these are managed at Sharvari Hospital.
Sphincter-preserving techniques such as seton, LIFT, FiLaC laser closure, VAAFT and advancement flap are chosen specifically to avoid dividing the sphincter muscle. The risk is not zero and rises with each previous operation, which is why the technique must match the tract anatomy shown on MRI.
Yes. For complex or recurrent anal fistula, MRI fistulography is the reference-standard investigation. It identifies secondary tracts, horseshoe extensions and undrained collections that clinical examination alone will miss. How we read each line of the report — and a real mapped case — is on our MRI fistula mapping page.
Get the tract imaged before anyone operates again. Ask for a pelvic MRI with fistula protocol (MRI fistulogram) and bring it to the consultation together with your previous operation notes, discharge summary and any earlier scans — the old notes tell us what was found and done last time, and the new MRI shows where the internal opening is, how much sphincter the tract now crosses and whether there is an undrained abscess or a second tract. A recurrence with pain but very little discharge can still hide a large collection: in one recent recurrent case the MRI found a 6 cm horseshoe abscess behind one small skin opening. The operation is then planned from that map, not from the outside opening.
For a heavily recurrent or horseshoe fistula a staged approach is common — drainage or seton placement first, definitive closure later. The expected number of stages is explained before consent.
A seton is a soft thread passed along the fistula tract. It drains infection and lets inflamed tissue settle so that the definitive procedure has a healthy field to work in. It is a stage in treatment, not a failure — see seton and staged fistula surgery.
Yes. Tubercular fistula-in-ano is under-recognised in India and Crohn's disease is a well-known cause of non-healing perianal fistula. Where suspected, these are investigated before further surgery, because no surgical technique alone will close a tract driven by underlying disease.
Complex, high and recurrent fistulas commonly need 6 to 8 weeks for full healing after the definitive procedure, and longer when treatment is staged.
Yes. Fistula surgery is covered under most health insurance policies and Sharvari Hospital offers cashless treatment with over 50 insurers, with pre-authorisation handled by the hospital desk.
Yes. Sharvari Hospital routinely treats patients first operated elsewhere. Please bring your previous operative notes, discharge summary and any prior imaging.
