ABSTRACT Background: Anal fissure is a longitudinal defect in the skin of the anal canal, which is common, mostly benign, and may be acute or chronic. The tear is usually superficial in the skin distal to the dentate line. Anal fissure is classified as acute and chronic. Thy typical symptoms are anal spasm, pain, and/or bleeding with defecation. Aim: In this review, we will look into the epidemiology, etiology, and updated management of anal fissure. Conclusion: Anal fissures are typical presentations to the emergency room and the primary care provider. Even if they are benign, they can lead to severe pain and impair the quality of life. Anal fissures are better handled by the inter-professional team. The disease can be handled in several ways; but, when conventional therapy fails, it is important to refer the patient to a colorectal surgeon who has greater experience with this disorder than any other health care provider. Atypical anal fissures associated with Crohn's disease or HIV should be treated with caution. Key Words: anal fissure, management of anal fissure, updated management of anal fissure, fissure surgery eIJPPR 2020; 10(5):60-63 HOW TO CITE THIS ARTICLE: Atef Mohamed Ibrahem, Ali Khalid Al-Khaldi, Ayman Mukhtar Afit Alzaid (2020).

The most frequent location for males and cause anal pain like an abscess, pruritus ani, anal fistula, females is the posterior midline, with more than 75% condyloma, cancers, Crohn's disease, ulcerative colitis, occurring at this location. About 25% of fissures occur in tuberculosis, sexually transmitted diseases, HIV, leukemia, the anterior region and are more prevalent in women. Less and AIDS [20]. Patients with underlying disorders such as than 1% of fissures are found off the midline area and are Crohn may have anal fissures at the primary locations. known to be atypical fissures [11]. Updated Management: Etiology: There is not any clear guideline on the management of anal The precise cause of anal fissure is unclear, however, it is fissure. Management aims to break the anal sphincter spasm assumed to be caused by trauma to the anal canal. Etiology cycle and improve blood flow into the fissured area, leading of an atypical fissure includes leukemia, herpes, syphilis, to healing [21]. Most of the primary anal fissures can be HIV, tuberculosis, anal cancer, ulcerative colitis, and medically managed. Conservative measures including only Crohn's disease. Trauma to the anoderm during the passage warm bathing of the perineum (sitz baths) and increased of hard stool, irritation caused by anoreceptive intercourse, intake of fiber (e.g. psyllium) can improve about 50% of anorectal surgery, and diarrhea [12]. Patients typically cases with acute anal fissure with a recurrence rate of 18.6% experience increased pressure within the anal canal in [22-24]. Warm sitz baths can heal anal fissures by a response to anal fissure. Many studies reported that the somatoanal reflex, leading to the relaxation of the internal internal anal sphincter resting pressure in patients with anal sphincter [25]. fissures is higher than the normal ones [13]. NONOPERATIVE MANAGEMENT: The relative ischemia of the posterior anal canal is another potential cause. Postmortem angiographic tests have found Non-operational therapy targets are simple and consist of that there is reduced blood flow to the posterior anal canal, three elements. The first aspect is the elimination of the which may also justify the elevated incidence of posterior underlying pathology, which is responsible for fissure midline fissure [14].

  • What Is an Anal Fissure?
    What is an Anal Fissure? This is a fairly common condition (number one cause of anal pain and bleeding -- more common than hemorrhoids) in which the lining of the anal canal becomes torn. This generally produces pain or burning, especially with passage of a bowel movement. Bleeding may also occur. A fissure usually occurs with constipation or after forceful passage of a large, hard bowel movement. However, fissures also may occur without straining, since the tissue lining the anal canal is very delicate. How is a fissure diagnosed? When a fissure is present, a digital rectal exam is usually painful. The fissure can be usually be visualized by an external inspection of the anus, or an anoscope can be used to determine the extent of the tear. How is a fissure treated? • Warm tub or sitz baths several times a day in plain warm water for about 10 minutes. • Stool softeners or fiber to provide a regular soft, formed bowel movement. • Creams and/or suppositories (Preparation-H or Anusol or product with lidocaine added). • May add Nitroglycerin to anus to relieve spasm and pain thus allow healing. Most fissures will heal within several weeks, but surgery may be necessary if symptoms persist. Surgical treatment usually consists of cutting a portion of the muscle in the anal canal (sphincterotomy). This procedure reduces the tension produced by the fissure and allows it to heal. Of course, the best treatment is prevention, and ingestion of a high fiber diet to promote bowel regularity is of utmost importance. What do you do After. .?
