Operation
– Normal and abnormal symptoms
A chronic fissure is a non-healing wound in the anal canal that has been present for weeks or months.
During a fissurectomy, the wound edges and base of the wound are excised and scraped, so that the wound can granulate from the bottom up on a healthy wound base.
Botulinum toxin is injected into the anal sphincter under general anesthesia. Postoperative pain lasts for about 3 days.
A bottle of botulinum toxin costs 170€ in pharmacies and is not reimbursed by the medical aid (INAMI – RIZIV).
Botulinum toxin temporarily relaxes the anal sphincter, increasing the blood supply to the fissure so that it can heal and reduce spasms and pain. The effect of botulinum toxin disappears completely after 3 months.
