What is anal fissure?
Now it is ninety-nine cold winters. People have less outdoor activities. In order to get rid of the cold, some people like to eat spicy hot pot, barbecue and other foods. These factors virtually trigger and aggravate the occurrence of anorectal diseases, including anal fissures. In the clinic, we found that patients with anorectal disease in the hospital in winter are significantly more than in summer.
So, what is anal fissure?
In clinical practice, we often hear patients describe that they dare not defecate for a period of time, and the anus is like a crack when defecation, pain and discomfort, blood drips out of the stool, or blood on the paper, and the stool also becomes It's dry. The patient asked, what disease is this? Some patients asked if the anus was split?
Listening to the patient's description, we felt that these conditions were in line with the clinical manifestations of anal fissure. After checking the patient's part, we told the patient that the patient did have anal fissure.
Academically, an anal fissure is a non-specific radial longitudinal split or ulcer on the skin of the anal canal below the dentition line. It is generally fusiform or oval, about 0.5 to 1.0 cm long, and the position of the slit is not deep, just in the anus near the anal opening.
Anal fissure is a common anorectal disease with a relatively high incidence, which is only lower than that of hemorrhoids. The incidence ranks second in anorectal diseases, accounting for 15%-22% of anorectal diseases. The incidence is mainly young and middle-aged, with more women than men. It usually occurs in the anterior and posterior median of the anal canal. More than 75% of the anal fissures are in the posterior median of the anal canal, followed by the anterior median. Females often have the same disease in the anterior and posterior positions. Anal fissures on the left and right sides of the anal canal are rare. . Traditional Chinese medicine vividly refers to anal fissures as "split hemorrhoids" and "uncut hemorrhoids".
How do you know that you have anal fissure? What are the main symptoms of anal fissure?
1. Anal pain
Anal pain caused by a typical anal fissure is characterized by periodic pain. The specific manifestations are pain in the anus during defecation, with paroxysmal knife-cutting pain or burning pain, and the pain decreases or disappears within a few minutes to more than ten minutes after defecation, which is called the pain intermittent period. Later, the pain was severe due to persistent spasm of the sphincter, which usually lasted for several hours to relieve gradually. In severe cases, coughing and sneezing can cause pain and radiate to the pelvis and lower limbs. It will not be relieved until the anal sphincter gradually relaxes and the contraction is weak. It presents a cyclical vicious cycle of "pain-relief-severe pain-stop", which makes people painful.
2. Bleeding during stool
It is bloody and bright red, usually dripping blood, but the amount is small, or it is only attached to the surface of the stool, and sometimes it is just blood stained on toilet paper. It should be pointed out that the characteristics of anal fissure blood in the stool are: bleeding during stool, blood is bright red, accompanied by anal pain, this feature is different from internal hemorrhoid bleeding.
Many patients cannot tolerate the pain caused by anal fissures and tend to hold back their stools and urine habitually. Over time, the stools become dry and difficult to pass. The stools accumulate in the intestines for a long time and form constipation. Constipation will make the anal fissure more and more serious, and the pain will become more and more severe, making it difficult for the anal crack to heal on its own.
The above three points are the main symptoms of anal fissure. If you have these conditions, you should go to the hospital to ask a specialist to see if it is anal fissure. Because of the diagnosis of anal fissure, these symptoms alone are not enough. On the basis of these symptoms, a local examination is also necessary. This is very important. The local examination and symptoms are consistent with the anal fissure before the diagnosis of anal fissure can be made.
