Fistulotomy recovery: week by week

What this experience covers

A composite picture of what people commonly experience during the weeks of recovery after a fistulotomy — a procedure where the fistula tract is opened and left to heal from the inside out. This draws from multiple anonymized experiences and represents common patterns, not any single person’s story.

Common elements: the surgery itself, first week pain management, wound packing changes, the slow visible filling of the wound, key milestones, and the weeks-long timeline that is longer than most people expect.

The pattern

Surgery day

People describe fistulotomy as a relatively short procedure, often under general anaesthesia. Waking up, the area is numb or packed, and pain is initially managed with medication. Many people go home the same day. The most common surprise: learning that the wound will be left open, not stitched.

Common reactions:

  • Relief that the procedure is done after weeks or months of planning
  • Anxiety about caring for an open wound in a sensitive area
  • Feeling groggy and sore but not in acute pain yet

Week 1: managing the pain

Once the anaesthesia and initial pain medication wear off, the first week is commonly described as the hardest. Pain is most intense in the first 3 to 5 days, especially during and after bowel movements.

What people describe:

  • Pain that is sharp during bowel movements and aching between them
  • Stool softeners and fiber as essential, not optional
  • The first post-surgery bowel movement as a significant anxiety event
  • Dressing changes that are uncomfortable but manageable
  • Limited mobility and time off work for most people

Weeks 2 to 3: wound packing and settling in

By week two, the acute pain has typically reduced. People shift from pain management to wound management. District nurses, practice nurses, or self-care routines handle packing changes.

Common experiences:

  • Wound packing changes that become routine, though not pleasant
  • Gradually increasing activity — short walks, light tasks
  • Ongoing drainage that requires dressings and pads
  • Learning to read the wound’s progress and what healthy healing looks like

Weeks 4 to 6: visible progress

This is when most people describe seeing real change. The wound visibly fills in from the bottom, and the surface area shrinks. Milestones that people commonly note:

  • First comfortable shower without wincing
  • First normal bowel movement without significant pain
  • Sitting comfortably for longer periods
  • Returning to work or regular activities
  • Needing fewer or no dressings

Weeks 6 to 8 and beyond: the final stretch

Healing continues but slows. People describe this phase as requiring patience. The wound may look nearly closed but still needs time to fully mature. Some people heal in 6 weeks; others take 10 to 12.

The emotional arc at this stage is generally positive but tinged with impatience. People are ready to be done, and the last stretch of healing often feels the longest. Follow-up appointments confirm healing progress and provide reassurance.
