Anal fistula and anal fissure
“Currently it’s painful around the anus and there is blood in my stool. What happened to me?” Since the presence of blood in stool and anal pain are signs of anal fistula and aneurysm, so it is suggested that the elderly should receive colonoscopy examination to rule out the possibilities of colon cancer and other intestinal diseases.
Causes of anal fistula
Anal fistula is a disease of the anus, commonly caused by inflammation that leads to a formation of cannel that linked the rectum to the outer anus.
Treatment of anal fistula
For patients with anal fistula, the best treatment is to have surgical resection of the fistula. After surgery patients can be discharged on the same day. Though anal fistula may recur, it is rare in Asians.
Anal fissure is caused by over-stretching of the anal sphincters, making it hard to defecate and over-straining during defecation, which eventually becomes anal fissure.
How to differentiate anal fissure and hemorrhoids?
Many patients would mistakenly consider that having blood in stool must be the signs of hemorrhoids. Therefore doctors have to understand the fecal bleeding condition besides routine clinical examination.
Although both anal fissure and hemorrhoids would lead to blood in stool, the former one causes extreme pain to patients. Most patients with hemorrhoids do not feel any pain during defecation except those having anal fissure. Therefore, based on the pain sensation and clinical examination, doctors would be able to differentiate anal fissure and hemorrhoids.
Treatment of anal fissure
Early stages of anal fissure can be treated by medications to soften the stool and making it easier to be defecated. Pain medications can also be prescribed to eliminate pain. For later stages of anal fissure, surgeries may be required to loosen the anal sphincter and enlarge the anus.
