Anal fissures in children
The above measures apply to children who have a fissure as much as to adults. In children, the pain often makes them 'hold on' to their faeces. This may lead to a vicious circle as then even larger and harder faeces form, which causes more pain when they are finally passed. Therefore, in addition to the above measures, a short course of laxatives may be prescribed for children with an anal fissure. The aim is to make sure their faeces are soft and loose whilst the fissure heals.
What if the anal fissure does not heal?
An anal fissure will heal within 1-2 weeks in most cases, but takes longer to heal in some cases. A fissure lasting more than six weeks is called a chronic (persistent) anal fissure. Treatment with an ointment containing glyceryl trinitrate (GTN) may be advised if you have a chronic anal fissure. This often works, but some people require a minor surgical operation to cure a chronic anal fissure.
Prevention of a further anal fissure
If you have had one anal fissure, after it has healed you have a higher than average chance of having another one at some time in the future. The best way to avoid a further fissure is not to become constipated by using the measures described above. That is, a high fibre diet, fluid, etc. Leaflets that list foods high in fibre are commonly available. Ask your practice nurse for one if you cannot obtain one.
