In addition, anal stretching can increase the rate of flatus incontinence. The incidence of incontinence is thought to be due to a lack of standardization and that proper technique results in little chance that it will occur.In the early 1990s, however, a repeatable method of anal dilation proved to be very effective and showed a very low incidence of side effects. Since then, at least one other controlled, randomized study has shown there to be little difference in healing rates and complications between controlled anal dilation and LIS, while another has again shown high success rates with anal dilation coupled with low incidence of side effects. Fissurectomy
Fissurectomy involves excision of the skin on and around the anal fissure and excision of the sentinel pile if one is present. The surgical wound can be left open. New skin tissue grows and it heals. Epidemiology
The incidence of anal fissures is around 1 in 350 adults. They occur equally common in men and women and most often occur in adults aged 15 to 40. See also
