If you ask what is the item you are least willing to check in the physical examination? Many people blurt out: digital anal examination, followed by stool examination. In fact, these two items are also the two items most easily discarded in the medical examination.
It is estimated that many people do not know that the humble digital anal examination is the primary screening for rectal cancer.
Misunderstanding: Confusing hemorrhoids and rectal cancer, delaying treatment
It is understood that there is no inevitable relationship between hemorrhoids and rectal cancer, but most people neglect to observe their own physical condition and confuse the early symptoms of hemorrhoids and rectal cancer, which leads to delayed treatment and delays in treatment.
During defecation, some people feel pain in the anus, difficulty in defecation, and blood in the stool. They think it is caused by hemorrhoids. After defecation, some people "sneer" and flush immediately without carefully observing their stool. Everyone knows that blood in the stool, abnormal stool characteristics (unformed, frequent), and frequent abdominal pain may all be signs of rectal cancer.
Usually digital anal examination is divided into two parts: extra-anal digital examination and intra-anal digital examination. The extra-anal digital examination is when the doctor puts on the gloves, touches the anus with the index finger for induration, swelling, tenderness, fluctuations, and checks for fistulas, cords and directions under the anal skin.
The digital anal examination is the digital anorectal examination. After the medical examiner wears gloves or finger cots, apply some lubricating oil to the index finger and anal area, and extend the index finger into the rectum for examination. In the stool examination, the physical examiner needs to take more samples before the doctor can find out whether there is "occult blood" and check whether it contains excessive red blood cells. Therefore, early digital anal examination and stool examination are very important.
What diseases can be detected by a simple digital anal examination?
Anal fistula, anal fissure, anal papilla hypertrophy, perianal abscess, perianal eczema and other perianal diseases;
Lower mass and intestinal mass; male prostate condition, check whether the prostate is enlarged or enlarged;
Patients with constipation can determine whether they are outlet obstructive constipation;
In the emergency department, patients with rupture and bleeding of ectopic pregnancy can feel the fluctuating sensation in the rectum and uterus through the digital anus examination, combined with clinical symptoms, quickly make judgments, thereby saving valuable time for correct treatment.
4 types of symptoms do anal digital examination in time
Changes in bowel habits are the earliest and most common symptoms of rectal cancer. Due to the irritation of the cancer, the patient may have an increase in the number of stools for no obvious reason or alternate constipation and diarrhea, or a feeling of incomplete defecation in a short time. As the disease progresses and the focus increases, cancer can block the rectal outlet, causing symptoms such as constipation, thinning of the stool, deformed stool, and abdominal distension.
Changes in stool characteristics may cause thinning of stool, blood and mucus in stool. 80% to 90% of rectal cancer may have blood in the stool, the blood is bright red or dark red, often mixed with mucus or pus. Therefore, when such problems arise, you must not ignore the digital anal examination.
Pain in the anus is common in anal fissures and perianal abscesses. Perianal abscess should be incised and drained as soon as possible. Frequent pain in the anal mouth and bleeding of pus and blood are mostly symptoms of anal fistula, and digital examination can confirm the diagnosis.
Hemorrhoids are the most common disease, mainly manifested by blood in the stool and prolapse of lumps. It is easy to be confused with rectal cancer clinically, but most of them can make a correct diagnosis through digital anal examination.
Doctors suggest: rectal cancer is younger, early diagnosis is very important
In recent years, the incidence of colorectal cancer in China has shown an upward trend. In the past, rectal cancer was more common in men over the age of 40, but now a high-fat, low-fiber diet, chronic ulcerative colitis, colorectal adenoma, colorectal polyps, etc. are all risk factors for colorectal cancer.
The doctor reminded that rectal cancer is showing a trend of getting younger. Children with a family history of colorectal cancer are more likely to get the disease than the general population, and sedentary office workers also need to pay special attention.
Digital anal examination is not unsuitable for the crowd, and there will be no adverse reactions. There is no strict age limit. Adolescents and elderly people can accept the examination. Doctors recommend that you reduce your intake of alcohol and fried foods, eat less barbecue, increase the proportion of fresh vegetables and fruits in your diet, and eat more crude fiber foods. Sedentary office workers need to exercise more.
Moreover, during the examination, the male and female doctors are separated. During the examination, the doctor will try to communicate with the examinee to relieve the examinee’s tension and relax. "Early diagnosis, early treatment", if the check is abnormal, the doctor will recommend further colonoscopy to determine whether you have rectal cancer.
