Diagnosis of anal fissure
(A) Clinical manifestations
1.Symptoms Anal fissures are usually found at 6 and 12 o’clock in the truncated position of the bladder; symptoms are mainly pain, bleeding and constipation, and are mutually causal.
(1) pain: it is cyclical, and the pain increases during defecation, with paroxysmal knife-like pain or burning pain, and the pain decreases or disappears within a few minutes to more than ten minutes after defecation, which is called intermittent pain period. Subsequently, the pain is severe due to persistent spasm of the sphincter muscle, which often lasts for several hours before it can be gradually relieved. In severe cases, coughing and sneezing can cause pain that radiates to the pelvis and lower extremities. The degree and length of pain varies greatly from person to person. Pain is also the main reason for most patients to visit the clinic.
(2) Bleeding: bleeding is seen during stool, usually blood stained by hand paper or dripping blood, bright red in color, but in small amounts or only adhering to the surface of the stool.
(3) Constipation: Patients often have habitual constipation, and dry stool often tears the skin of the anal canal and causes anal fissure, and they are reluctant to defecate regularly because of the fear of pain in the anus during stool, which leads to prolonged residence time of stool in the rectum and excessive absorption of water, aggravating constipation and forming a vicious circle.
2.Signs
(1) Fissure: early patients have fresh, superficial, red-colored trauma with soft texture and no fibrous tissue growth. The traumatic surface is grayish or grayish, hard, and can be touched with striated hard nodes
(2) Pathological changes in the anal canal: there are no pathological changes in the early stage, but six kinds of pathological changes such as “cylinder mouth” thickening, thickening of the pectineal zone, enlarged connective tissue external hemorrhoids, anal hypertrophic papillae, subcutaneous fistula and anal sinusitis are formed around the trauma, the anal canal and the dentate line over a long period of time.
(B) Other auxiliary examinations
1.Local visual examination The examination of anal fissure is mainly local visual examination, the patient usually takes the lateral lying position, riding position or knee-chest position, pay attention to the warmth and light, ask the patient to cooperate and relax the anus, the examiner gently separates the anus to both sides with both thumbs and index fingers, from outside to inside, check one by one, do not miss.
2. Other rectal examinations, anoscopy and speculum examination often cause severe pain and aggravate the patient’s suffering, so they are generally not used as routine examination items.
In short, the main points of diagnosis of anal fissure are as follows.
(1) Medical history: Most of them have a history of constipation.
(2) Clinical symptoms: periodic anal pain, blood in the stool, constipation, etc.
(3) Anal canal signs: longitudinal fissure trauma on the anal canal skin.
(4) Finger palpation or anoscopy: note that this type of examination should preferably be performed under anesthesia. Common complications of anal fissures, such as sinus tracts or fistulas, sentinel hemorrhoids, and anal papillary hypertrophy, can be detected.
(5) Clinical differentiation is needed from anal chancre, anal canal skin abrasion, anal canal tuberculous ulcer, Crohn’s disease anal canal ulcer, anal hard chancre ulcer, early anal canal cancer, and anal canal epithelial defect.
(C) Disease staging Generally divided into two stages, namely.
1.Early anal fissure There is a small poke-shaped ulcer on the skin of the anal canal with shallow trauma, bright red color, neat and elastic edges, no scar or hard node formation, with a short course and easy to cure.
2, old anal fissures history of repeated attacks of anal fissures, early anal fissures without timely and appropriate treatment, ulcer color light white, deep bottom, irregular trauma edge, “jar mouth” thickening, the bottom of the formation of flat and hard gray and white tissue (pectineal belt), poor elasticity, more difficult to heal.
IV. Treatment of anal fissure
The treatment principle of anal fissure is to open the stool and eliminate the fissure. Soften the stool, keep it open, stop the pain, release the spasm of the sphincter, interrupt the vicious cycle, and promote the healing of the wound.
There are many ways to treat anal fissures. If the lesion is early, it can be cured by actively treating constipation, keeping the stool open, protecting the ulcerated wound and preventing infection. If early anal fissures are not treated in time, recurrent attacks and local pathological changes are formed, conservative treatment is often ineffective and surgical treatment is required.

4, relieve mental tension Most anal fissure patients have a fear of defecation, when not defecating, first stool not defecate, after the emergence of a number of bowel movements, then have to defecate, resulting in dry stool, fecal diameter thickened, difficult to discharge, anal pain increased. In fact, in most cases, the stool of patients with anal fissures is only dry and hard at the front and normal at the back. Therefore, it is very important for the doctor to explain clearly to the patient the process of defecation in order to relieve the patient’s tension. The author found that many patients after anal fissure surgery still have this psychological barrier to defecation, which leads to patients feeling that the surgical result is not satisfactory.
