What to do for perianal abscess

There are several tests for perianal abscess. 1. Routine anorectal examination: Check the extent of redness and swelling, and check whether there is mucus flowing out of the tooth line to determine the location of the internal opening.

1. Touch: Digital examination is very important. Whether it is at a low or high position, digital examination is sometimes more accurate than B-ultrasound.

2. Routine blood test: The severity of the abscess can be determined by a routine blood test.

3. B-ultrasound examination: B-ultrasound has been widely used in the diagnosis of anal fistula and perianal abscess. Experienced examiners can accurately describe the direction of the abscess cavity and fistula, its relationship with the sphincter, and the location of the internal opening.

4. CT and MRI examinations are mainly used for high-position abscesses that cannot be seen or touched. Anal inspection Use your thumb to gently separate the patient's buttocks and observe whether there are any loose objects, external hemorrhoids, fistulas, abscesses, anal fissures, etc. in the anus and surrounding areas. Rectal digital examination is also called anal finger examination. There are many reasons for anorectal abscesses, but intestinal flora imbalance and decreased immunity are two fundamental reasons.

Preventing intestinal flora imbalance and improving immunity are the fundamental ways to prevent perianal abscesses. The examiner wears a glove on his right hand or a fingertip on his right index finger, applies lubricating oil, and places the front end of his right index finger at the anus. After the patient adapts, gently insert the finger into the anus. First test the tightness of the anal sphincter, then check the anal canal and rectum in turn, paying attention to whether there is tenderness, lumps, fluctuations, stenosis, etc. around the intestinal wall. On the anterior wall of the rectum, men can touch the prostate, and women can touch the cervix. When the finger is pulled out, observe whether there is blood and mucus on the glove. Anoscopy: Apply lubricating oil to the anoscope, slowly insert it into the anus, remove the core, and observe the color of the rectal mucosa, rectal valves, ulcers, polyps, tumors, foreign bodies, etc. from deep to shallow. Slowly withdraw the anoscopy to observe whether there are lesions near the rectum and dental floss, such as fistulas, hemorrhoids, etc. Be brave in the inspection, and it will be checked soon.
