Is anal digital examination useful as a physical examination item? Why?

Anal finger examination, also known as rectal finger examination, is an examination method for medical staff to put their fingers into the anus and lower rectum of patients after putting on gloves for disinfection in a very relaxed state to explore abnormal masses. Anal digital examination is still very useful as a routine physical examination.

First, anal finger examination is useful. The anus is the end of the digestive tract and the outlet of stool. If the cells attached to its surface turn into abnormal cells whose growth is out of control, it is called anal cancer. Anal cancer doesn't always have symptoms, but when there are symptoms, we must check them in time. These symptoms include anal bleeding, pain in or around anus, foreign body or lump sensation in anus, anal pruritus, etc. In addition to finger examination of anus, visual inspection of anus, anoscopy, and taking a small amount of tissue from anus for biopsy. Are common inspection methods. If there is no problem in one examination and the symptoms persist, regular follow-up is needed. Therefore, anal visual examination and rectal digital examination are the most commonly used, direct, simple and economical methods to diagnose anal abscess and anal fistula. If you are not sure, you can do magnetic resonance imaging and CT imaging to help diagnose.

Second, what is the disease of anus? Common anorectal diseases include hemorrhoids, anal fissure, perianal abscess, anal fistula, rectal prolapse, anal pruritus, anal eczema, anorectal cancer and so on. The common symptoms of anorectal diseases mainly include bloody stool, constipation, prolapse, pain, swelling, increased secretion and the anus damp. If the blood in the stool drips down or squirts out, it is bright red and painless, mostly internal hemorrhoids. If the stool is mixed with mucus and pus, the color is dim, and the anus has a feeling of falling, the possibility of anorectal cancer should be considered. Blood is bright red, accompanied by anal pain and difficulty in defecation, mostly anal fissure. Mucous bloody stools, dark red in color, accompanied by abdominal pain, loose stool, increased stool frequency, mostly chronic colitis.

The anus is an important part of the human body, so we must pay attention to hygiene, change clothes frequently and clean frequently, which can reduce the possibility of cold diseases. Usually eat less spicy food, don't drink, don't stay up late, which is very helpful to your health.
