Recurrence or failure to heal?
New swelling after a genuinely healed interval differs from a wound that never stopped draining. Build a timeline rather than simply calling the operation unsuccessful.
What is reassessed?
The internal opening, branches, abscesses, continence and previous surgery are reviewed. MRI may help map altered anatomy. Bowel symptoms or recurrent inflammation may prompt evaluation for Crohn’s disease.
Should the same operation be repeated?
The next procedure should address the likely reason for persistence. Ask what the new plan changes and how healing is balanced against continence. Drainage may precede a closure attempt.
