At a glance

Having a fistulectomy scheduled brings a mixture of relief and anxiety — relief that a plan exists, and anxiety about the surgery and recovery ahead. This guide covers what people commonly describe about the preparation phase, the procedure itself, and the early recovery.

Fistulectomy is one of the surgical options for treating an anal fistula. It involves removing the fistula tract entirely, leaving a wound that heals by secondary intention (from the inside out). It is typically performed as a day case under general anaesthesia.

The preparation period

People describe using the time between scheduling and surgery for practical preparation:

  • Stool management — starting fibre supplements and stool softeners days before surgery to ensure soft stools from the first post-operative bowel movement
  • Wound care supplies — gauze, pads, comfortable underwear, sitz bath basin
  • Home preparation — easy meals, comfortable seating, and a setup that minimises the need to move around unnecessarily in the first few days
  • Work arrangements — most people plan for one to three weeks off, depending on the physical demands of their job
  • Support — arranging for someone to help with the first day or two, particularly with wound care

The procedure

Fistulectomy is typically performed under general anaesthesia as a day case. People describe:

  • The procedure itself being shorter than expected — often thirty to sixty minutes
  • Waking up with soreness at the surgical site but relief that it is done
  • Going home the same day in most cases
  • Receiving wound care instructions and follow-up arrangements

The early recovery

The first week after fistulectomy is the most challenging:

  • Pain management — prescribed pain relief, sitz baths, and rest
  • Wound care — daily cleaning, dressing changes, and possibly packing changes
  • The first bowel movement — anxiously anticipated but manageable when stools are soft
  • Drainage — the wound produces discharge that gradually decreases
  • Activity — gentle walking is encouraged; prolonged sitting is avoided

The longer journey

After the first week, recovery becomes a routine of daily wound care and gradual return to normal activities. The wound heals slowly — visible progress is best measured week to week rather than day to day. Follow-up appointments with the surgical team allow for professional wound assessment and reassurance about the healing trajectory.

The complete healing journey takes weeks to months, but the daily burden eases progressively as the wound shrinks and drainage decreases.

Common questions

What is the difference between fistulotomy and fistulectomy?

Fistulotomy involves cutting open the fistula tract so it can heal as a flat wound from the bottom up. Fistulectomy involves removing the entire fistula tract as a piece of tissue. Fistulectomy creates a larger wound but removes the tract completely. Both are common procedures for anal fistula, and your surgeon will recommend the approach best suited to your specific fistula.

How do I prepare for fistulectomy?

Practical preparation includes starting stool softeners and fibre supplementation several days before surgery, arranging time off work (typically one to three weeks depending on the wound), stocking wound care supplies, and preparing meals in advance. Ask your surgical team about any specific pre-operative instructions such as fasting requirements.

How long is fistulectomy recovery?

Recovery involves wound healing by secondary intention, which typically takes four to twelve weeks depending on the size and depth of the wound. The first week or two are the most uncomfortable. Most people return to light activity within one to two weeks and to more demanding activity within three to six weeks.

Will I need wound packing after fistulectomy?

Many fistulectomy wounds are packed initially to promote healing from the base. Packing changes are done by a nurse or eventually by the patient themselves. The need for packing decreases as the wound heals. Not all wounds require packing — some surgeons prefer to manage with simple dressings.

See all the signs

For this topic, get medical advice if you notice:

  • Rectal bleeding — always worth getting checked
  • Unexplained weight loss
  • Persistent change in bowel habits
  • Severe or worsening pain

Recording how you feel is not the same as being checked. These are the signs that need a doctor’s attention.

Call 911 or go to the emergency room now if you have:

  • bleeding that will not stop, a lot of blood (the toilet water turns red, or you pass large clots), or any bleeding with feeling faint or dizzy
  • fainting, a racing heart or trouble breathing
  • confusion or slurred speech, extreme shivering, no urine in a day, or blotchy skin
  • sudden severe belly pain, or a swollen, hard belly with vomiting or not passing stool or gas
  • you cannot pass urine at all, or your bladder feels full and painful and you can’t empty it
  • redness, swelling or severe pain spreading quickly around your anus, genitals or groin, especially with a fever or feeling very ill
  • a fever with a painful swelling near your anus if you have diabetes or a weakened immune system (for example, from chemotherapy or transplant medicines)
  • black, tarry stools

Call your doctor or go to urgent care today (or the ER if you can’t be seen today) if you have:

  • a temperature of 100.4°F (38°C) or higher, chills, vomiting, or feeling generally unwell
  • pain that is getting worse over days, or severe pain that stops you sitting or sleeping
  • a hot, swollen or very tender lump near your anus or at the top of the crease between your buttocks, or foul-smelling discharge
  • trouble urinating
  • bleeding that is getting heavier or more frequent, or blood mixed into your stool
  • feeling much more tired than usual, looking pale, or getting out of breath more easily than you used to
  • not passing stool for several days, or new belly pain

Make an appointment with your doctor if:

  • you have never had these symptoms checked by a doctor or nurse — whatever your age
  • you have had rectal bleeding for more than 3 weeks
  • your bowel movements have been looser, thinner or more frequent than usual for 3 weeks or more, or you have lost weight without trying
  • symptoms have not settled after a week or so, or keep coming back
  • you notice a new lump near your anus, between your buttocks or in your belly, or an itch or discharge that does not clear
  • you have new leakage or trouble controlling your bowels
  • you are 45 or over, or have a family history of bowel cancer or inflammatory bowel disease, and any of these symptoms are new for you

If you are unsure, it is always reasonable to ask. If things feel overwhelming, call or text 988 (Suicide & Crisis Lifeline) or chat at 988lifeline.org, any time. If you don’t feel safe, call 911.
