Fistulotomy and fistulectomy: the highest-cure operation for simple, superficial fistula
Fistulotomy lays a superficial fistula tract open along its whole length so it heals from the base up; fistulectomy removes a mature, fibrosed tract instead. Both suit early or simple superficial tracts that involve little sphincter muscle, and both carry the highest published cure rate. Day-care; desk work in 3–7 days (results vary). Performed by Dr. Kundan Kharde at Sharvari Hospital, Pimple Nilakh, Pune — 5 min from Wakad.
Who is this operation for?
These are the first two rows of Dr. Kharde's framework. An early, simple, superficial tract is laid open (fistulotomy). A mature, fibrosed superficial tract is removed whole (fistulectomy), because a hardened tunnel that is only opened tends to recur. Neither is used beyond 30–50% of the external sphincter — that tract needs a sphincter-preserving operation. Almost every fistula at Sharvari Hospital is imaged before surgery — MRI fistulogram or trans-rectal ultrasound — and the tract on that scan decides the operation (how Dr. Kharde decides).
How is it done?
- Anaesthesia and probing. Spinal or short general anaesthesia; a probe confirms the path seen on imaging.
- Lay-open (fistulotomy). The tissue over the probe — skin and the few sphincter fibres the imaging has shown — is divided, opening the tract into a shallow groove.
- Or excision (fistulectomy). For a fibrosed tract, the whole tunnel is cut out as a strip.
- Curettage and marsupialisation. Granulation is scraped away and the wound edges stitched to the base so it heals faster.
- Dressing. The wound is left open to heal from below; the bulk of the external sphincter is untouched.
About 20–40 minutes · an open wound the length of the tract · the bulk of the external sphincter preserved.
What does recovery look like?
| Day | Discharge & follow-up | Dressing & bowel movement | Return to work |
|---|---|---|---|
| Day 1 | Same-day discharge after observation; walking and normal diet that evening. | Open wound, light dressing; dressing routine taught; first bowel movement next day with a stool softener. | Rest at home; antibiotics and painkillers as prescribed. |
| Day 7 | Free first review at the hospital. | Twice-daily sitz baths; dressing after each bowel movement; the wound is checked to be healing from the base. | Desk work from Day 3–7; avoid gym and cycling (results vary). |
| Day 30 | Healing review; fistulotomy wound usually closed, fistulectomy may need a few more weeks. | Wound shallow and dry; minor early change in gas control usually settled. | Resume gym, cycling and long sitting. |

What are the risks and the alternatives?
- •Bleeding: minor spotting is usual; heavy bleeding is uncommon and is an emergency (we are open 24×7).
- •Infection: fever, rising pain or new swelling needs review; antibiotics are prescribed routinely.
- •Non-healing or recurrence: published series report healing in roughly 90–95% of simple superficial tracts (literature range, not Sharvari data) — the highest of any technique. Failure is usually a missed branch or a bridged wound; results vary.
- •Continence change: low risk when the tract is truly superficial; some patients notice minor early changes in gas control. The risk rises steeply with the amount of sphincter divided — hence imaging first and the 30–50% threshold.
- • Alternatives: LIFT, FiLaC (laser), VAAFT, Seton (staged) — the imaging decides which.
Technique selection follows the ASCRS Clinical Practice Guideline for Anorectal Abscess, Fistula-in-Ano and Rectovaginal Fistula (2022).
How does Fistulotomy & fistulectomy compare?
Fistulotomy is the benchmark the sphincter-preserving operations are measured against: highest published healing, at the price of a little divided muscle.
| Technique | Best for | Sphincter cut? | Day-care? | Typical return to desk work | Published healing range* | Recurrence risk |
|---|---|---|---|---|---|---|
| Fistulotomy / fistulectomy (this page) | Simple, superficial tract, <30% sphincter | Yes, minimal | Yes | 3–7 days | ~90–95% | Low |
| LIFT | Trans-sphincteric tract; intact sphincter needed | No | Yes | 5–10 days | ~60–80% | Moderate |
| FiLaC (laser) | Trans-sphincteric tract; patient wants no cut | No | Yes | 2–5 days | ~60–70% | Moderate |
| VAAFT | Complex / branched tract, unclear internal opening | No | Yes | 3–7 days | ~70–80% | Moderate |
| Seton (staged) | Active sepsis; high / recurrent / horseshoe; Crohn's | No (drainage) | Yes (stage 1) | 2–5 days per stage | Bridge to definitive operation | n/a |

Frequently asked questions
Why does fistulotomy have the highest cure rate? +
Because it removes the problem rather than sealing it: the whole tunnel is opened or excised, so no lining is left to re-form. Published series report healing in about 90–95% of simple tracts (literature range, not Sharvari data). The trade-off is an open wound and a little divided muscle; results vary.
Will fistulotomy affect bowel control? +
It should not when the tract is genuinely superficial — which is why it is reserved for tracts involving less than about 30% of the external sphincter and never used beyond 50%, measured on the pre-operative MRI or ultrasound rather than guessed on the table. Minor, temporary changes in gas control can occur.
Fistulotomy or fistulectomy — what is the difference? +
Fistulotomy opens the tract and leaves a shallow groove that heals in; fistulectomy cuts the whole tract out as a strip. Fistulotomy heals faster and suits an early, soft tract. Fistulectomy suits a mature, hardened tract that would recur if only opened; its wound is larger.
How long is the wound open? +
A fistulotomy wound usually closes over 3–5 weeks, a fistulectomy wound over 4–6 weeks, healing from the base upwards. Twice-daily sitz baths and a dressing after each bowel movement stop the surface bridging over too early. Desk work is possible well before closure; healing time varies with tract length.
When is fistulotomy NOT recommended? +
When the tract crosses more than 30–50% of the external sphincter, sits high or anteriorly in a woman, is recurrent, branched or horseshoe, or is linked to Crohn's disease or weak control. Those tracts get LIFT, FiLaC, VAAFT or a staged seton plan.
