People often ask whether anal fissures are serious and what the consequences might be if they are not treated. Although treating anal fissures is not particularly difficult clinically, many patients, due to a lack of treatment knowledge and awareness of the condition, often delay treatment, which can cause some harm to their health. If an anal fissure is not treated, in addition to the pain during bowel movements and bleeding that the fissure itself causes, over time, it could also lead to conditions such as anal fistula and hypertrophied anal papillae. At the end of the fissure, a sentinel pile may develop. Due to the repeated irritation by fecal matter in an inflamed fissure, a linear ulcer may form. The skin and subcutaneous tissue around the anus might undergo fibrosis, thickening, or. form a hard lump. If the fissure repeatedly becomes infected, it can lead to the development of an anal sinus, and after infection, it may cause subcutaneous fistulas or abscesses. Of course, if an anal fissure persists over time, due to long-term spasm and fibrosis of the internal sphincter, it can lead to consequences such as anal stenosis.
